# Cosmo 项目开发文档
## 项目概述
Cosmo 是一个深空探索可视化平台，使用 Three.js 在浏览器中实时渲染太阳系、星座、星系和探测器的 3D 场景。
**技术栈**：
- **前端**：React + TypeScript + Three.js + Vite
- **后端**：FastAPI + Python 3.11
- **数据库**：PostgreSQL 15+ (SQLAlchemy 2.0 异步)
- **缓存**：Redis 7+ (三层缓存架构)
- **数据源**：NASA Horizons API
**版本**：v0.0.9
---
## 已完成工作 (v0.0.9)
### 一、数据库架构升级 ✅
#### 1.1 数据库设计与实现
从静态文件驱动的架构升级为数据库驱动：
**数据库表结构**：
- `celestial_bodies` - 天体基本信息 (行星、卫星、探测器等)
- `positions` - 位置历史表 (时间序列数据)
- `resources` - 资源文件管理 (纹理、3D模型)
- `static_data` - 静态天文数据 (星座、星系、恒星)
- `nasa_cache` - NASA API 持久化缓存
**文件位置**：
- 数据库模型：`backend/app/models/db/`
- `celestial_body.py` - 天体模型
- `position.py` - 位置模型
- `resource.py` - 资源模型
- `static_data.py` - 静态数据模型
- `nasa_cache.py` - NASA 缓存模型
- Schema 文档：`backend/DATABASE_SCHEMA.md`
#### 1.2 数据库服务层
实现了异步数据库操作服务：
**核心服务** (`backend/app/services/db_service.py`):
- `get_celestial_body(body_id)` - 查询天体信息
- `get_celestial_bodies(type)` - 批量查询天体
- `get_latest_position(body_id)` - 查询最新位置
- `get_positions(body_id, start, end)` - 查询位置历史
- `save_position(body_id, time, position)` - 保存位置数据
- `get_static_data(category)` - 查询静态数据
- `get_resource(body_id, type)` - 查询资源文件
#### 1.3 三层缓存架构
实现了高效的缓存策略：
```
请求 → L1 (内存) → L2 (Redis) → L3 (数据库) → L4 (NASA API)
```
**L1 - 内存缓存** (已有):
- TTL: 10分钟
- 用途：当前时间的天体位置 (最热数据)
**L2 - Redis 缓存** (新增 `backend/app/services/redis_cache.py`):
- TTL: 当前数据 1小时，历史数据 7天
- 用途：NASA API 响应、会话数据、预计算结果
- 特点：进程间共享、持久化、分布式支持
**L3 - 数据库** (新增):
- 持久化存储
- 历史数据查询
- 复杂查询和统计
**L4 - NASA API**:
- 最终数据源
- 只在所有缓存未命中时调用
### 二、后端改进 ✅
#### 2.1 配置管理系统
实现了基于 Pydantic Settings 的配置管理：
**配置文件**：
- `backend/.env` - 实际配置 (不提交到 Git)
- `backend/.env.example` - 配置模板
- `backend/app/config.py` - 配置管理类
**配置项**：
- PostgreSQL 连接配置 (host, port, user, password, pool_size)
- Redis 连接配置 (host, port, db, password)
- 应用配置 (CORS, cache TTL, upload 设置)
**文档**：`backend/CONFIG.md`
#### 2.2 API 扩展
扩展了后端 API 端点 (`backend/app/api/routes.py`):
**新增端点**：
- `GET /api/celestial-bodies` - 获取所有天体
- `GET /api/celestial-bodies/{body_id}` - 获取单个天体
- `GET /api/static/constellations` - 获取星座数据
- `GET /api/static/galaxies` - 获取星系数据
- `GET /api/static/stars` - 获取恒星数据
- `GET /api/static/textures/{path}` - 提供纹理文件
- `GET /api/static/models/{path}` - 提供 3D 模型文件
**改进的端点**：
- `GET /api/probes` - 从数据库读取探测器信息
- `POST /api/probe-positions` - 优化缓存策略
- `GET /health` - 新增 Redis 和数据库健康检查
#### 2.3 数据迁移脚本
创建了完整的初始化和迁移脚本 (`backend/scripts/`):
**初始化脚本**：
- `create_db.py` - 创建数据库
- `init_db.py` - 初始化表结构
- `check_config.py` - 验证配置
**数据迁移**：
- `migrate_data.py` - 迁移天体基础数据
- `update_static_data.py` - 迁移静态数据 (星座、星系)
- `populate_resources.py` - 迁移资源文件记录
**辅助脚本**：
- `fetch_and_cache.py` - 预取并缓存 NASA 数据
- `list_celestial_bodies.py` - 列出所有天体
- `add_pluto.py` - 添加冥王星数据示例
#### 2.4 依赖管理
更新了后端依赖 (`backend/requirements.txt`):
**新增依赖**：
```
sqlalchemy>=2.0.0 # ORM 框架 (异步支持)
asyncpg>=0.29.0 # PostgreSQL 异步驱动
alembic>=1.12.0 # 数据库迁移工具
redis>=5.0.0 # Redis 客户端
aiofiles>=23.0.0 # 异步文件操作
pydantic-settings>=2.0.0 # 配置管理
```
### 三、前端改进 ✅
#### 3.1 从静态文件迁移到 API
**移除的静态文件**：
- `frontend/public/data/*.json` (所有 JSON 数据文件)
- `frontend/public/textures/*.jpg` (所有纹理文件)
- `frontend/public/models/*.glb` (所有 3D 模型)
**改为从后端 API 获取**：
- 天体数据：`/api/celestial-bodies`
- 静态数据：`/api/static/*`
- 纹理文件：`/api/static/textures/*`
- 3D 模型：`/api/static/models/*`
#### 3.2 组件更新
更新了前端组件以适应新的数据获取方式：
**修改的组件**：
- `src/components/CelestialBody.tsx` - 使用 API 获取天体和纹理
- `src/components/Probe.tsx` - 简化探测器渲染逻辑
- `src/components/Constellations.tsx` - 从 API 获取星座数据
- `src/components/Galaxies.tsx` - 从 API 获取星系数据
- `src/components/ProbeList.tsx` - 使用新的探测器数据结构
- `src/utils/api.ts` - 新增 API 调用函数
#### 3.3 API 工具函数
新增了 API 调用函数 (`frontend/src/utils/api.ts`):
```typescript
// 天体相关
export const getCelestialBodies = async ()
export const getCelestialBody = async (bodyId: string)
// 静态数据
export const getConstellations = async ()
export const getGalaxies = async ()
export const getNearbyStars = async ()
// 探测器
export const getProbes = async ()
export const getProbePositions = async (probeIds: string[])
```

# Cosmo 平台架构升级规划
## 一、现状分析
### 当前架构
- **前端数据**：静态JSON文件（galaxies, constellations, stars, probe-models）
- **后端数据**：NASA Horizons API实时查询 + 简单内存缓存
- **资源存储**：纹理和3D模型在前端 `public/` 目录
- **缓存策略**：内存缓存（进程级别，重启失效）
### 痛点
1. **数据管理分散**：前端JSON + 后端代码硬编码
2. **缓存不持久**：服务重启后需要重新查询NASA API
3. **资源管理混乱**：纹理、模型路径分散在前后端
4. **扩展困难**：添加新天体类型需要修改多处代码
5. **无历史数据**：无法查询天体历史轨迹
6. **性能问题**：NASA API查询慢（每个天体1-2秒）
### 未来需求
- 支持更多天体类型（彗星、小行星、系外行星等）
- 用户自定义天体
- 历史轨迹查询和时间旅行
- 性能优化（减少NASA API调用）
- 统一的资源管理
- 可能的多用户支持
---
## 二、技术方案
### 2.1 数据库方案
#### 推荐：PostgreSQL + SQLAlchemy
**选择理由**：
1. **功能强大**：支持复杂查询、全文搜索、JSON字段
2. **PostGIS扩展**：专门处理空间数据（未来可能需要）
3. **时间序列优化**：通过TimescaleDB扩展支持高效时间序列查询
4. **成熟生态**：Python生态支持好（asyncpg, SQLAlchemy 2.0异步支持）
5. **扩展性**：支持大规模数据和并发
**备选方案**：
- **SQLite**：适合单机部署，但功能和性能有限
- **MongoDB**：文档型数据库，但对关系查询支持不如PostgreSQL
#### 数据库设计
```sql
-- 天体类型枚举
CREATE TYPE celestial_type AS ENUM ('star', 'planet', 'moon', 'probe', 'comet', 'asteroid', 'galaxy', 'constellation');
-- 天体基本信息表
CREATE TABLE celestial_bodies (
id VARCHAR(50) PRIMARY KEY, -- JPL Horizons ID 或自定义ID
name VARCHAR(200) NOT NULL,
name_zh VARCHAR(200),
type celestial_type NOT NULL,
description TEXT,
metadata JSONB, -- 灵活存储各种元数据（launch_date, status等）
created_at TIMESTAMP DEFAULT NOW(),
updated_at TIMESTAMP DEFAULT NOW()
);
-- 位置历史表（时间序列数据）
CREATE TABLE positions (
id BIGSERIAL PRIMARY KEY,
body_id VARCHAR(50) REFERENCES celestial_bodies(id),
time TIMESTAMP NOT NULL,
x DOUBLE PRECISION NOT NULL, -- AU
y DOUBLE PRECISION NOT NULL,
z DOUBLE PRECISION NOT NULL,
source VARCHAR(50), -- 'nasa_horizons', 'calculated', 'user_defined'
created_at TIMESTAMP DEFAULT NOW()
);
CREATE INDEX idx_positions_body_time ON positions(body_id, time DESC);
-- 资源管理表（纹理、模型等）
CREATE TABLE resources (
id SERIAL PRIMARY KEY,
body_id VARCHAR(50) REFERENCES celestial_bodies(id),
type VARCHAR(50) NOT NULL, -- 'texture', 'model', 'icon'
file_path VARCHAR(500) NOT NULL, -- 相对于upload目录的路径
file_size INTEGER,
mime_type VARCHAR(100),
metadata JSONB, -- 分辨率、格式等信息
created_at TIMESTAMP DEFAULT NOW()
);
-- 静态数据表（星座、星系等不变数据）
CREATE TABLE static_data (
id SERIAL PRIMARY KEY,
category VARCHAR(50) NOT NULL, -- 'constellation', 'galaxy', 'star'
name VARCHAR(200) NOT NULL,
name_zh VARCHAR(200),
data JSONB NOT NULL, -- 完整的静态数据
created_at TIMESTAMP DEFAULT NOW(),
updated_at TIMESTAMP DEFAULT NOW()
);
-- NASA API缓存表（持久化缓存）
CREATE TABLE nasa_cache (
cache_key VARCHAR(500) PRIMARY KEY,
body_id VARCHAR(50),
start_time TIMESTAMP,
end_time TIMESTAMP,
step VARCHAR(10),
data JSONB NOT NULL,
expires_at TIMESTAMP NOT NULL,
created_at TIMESTAMP DEFAULT NOW()
);
CREATE INDEX idx_nasa_cache_expires ON nasa_cache(expires_at);
```
### 2.2 缓存策略
#### 三层缓存架构
```
请求 → L1 (内存) → L2 (Redis) → L3 (数据库) → L4 (NASA API)
```
**L1: 进程内存缓存**（已有）
- TTL: 10分钟
- 用途：当前时间的天体位置（最热数据）
- 实现：Python dict + TTL（已有cache.py）
**L2: Redis缓存**（新增）
- TTL:
- 当前时间数据：1小时
- 历史数据：7天
- 静态数据：永久（手动失效）
- 用途：
- NASA API响应缓存
- 会话数据
- 预计算结果
- 好处：
- 进程间共享
- 持久化（重启不丢失）
- 分布式支持
**L3: PostgreSQL数据库**
- 持久化存储
- 历史数据查询
- 复杂查询和统计
**L4: NASA Horizons API**
- 最终数据源
- 只在缓存未命中时调用
#### 缓存键设计
```python
# L1/L2 缓存键格式
"positions:{body_id}:{start}:{end}:{step}"
"static:{category}:{name}"
"texture:{body_id}:{type}"
# 示例
"positions:-31:2025-11-27:2025-11-27:1d"
"static:constellation:orion"
```
### 2.3 文件存储方案
#### 目录结构
```
cosmo/
├── backend/
│ ├── upload/ # 统一上传目录
│ │ ├── textures/
│ │ │ ├── planets/ # 行星纹理
│ │ │ ├── stars/ # 恒星纹理
│ │ │ └── probes/ # 探测器图标
│ │ ├── models/
│ │ │ ├── probes/ # 探测器3D模型
│ │ │ └── spacecraft/
│ │ └── data/ # 数据文件备份
│ └── app/
│ └── api/
│ └── static.py # 静态文件服务API
```
#### 文件访问
```python
# 后端提供统一的静态文件API
GET /api/static/textures/planets/earth.jpg
GET /api/static/models/probes/voyager1.glb
# 数据库记录
{
"body_id": "399",
"type": "texture",
"file_path": "textures/planets/2k_earth_daymap.jpg",
"url": "/api/static/textures/planets/2k_earth_daymap.jpg"
}
```
### 2.4 数据迁移路径
#### 阶段1：数据库基础设施（1-2天）
1. 安装PostgreSQL和Redis
2. 设置SQLAlchemy ORM
3. 创建数据库表结构
4. 数据迁移脚本：
- `CELESTIAL_BODIES` dict → `celestial_bodies` 表
- 前端JSON文件 → `static_data` 表
#### 阶段2：缓存层升级（1天）
1. 集成Redis客户端
2. 实现三层缓存逻辑
3. NASA API结果持久化到数据库
#### 阶段3：资源管理迁移（1天）
1. 迁移纹理文件到 `backend/upload/textures/`
2. 迁移3D模型到 `backend/upload/models/`
3. 建立资源表记录
4. 实现静态文件服务API
#### 阶段4：API重构（1-2天）
1. 新增数据库查询API
2. 前端调整为从后端API获取所有数据
3. 移除前端静态JSON文件依赖
#### 阶段5：优化和测试（1天）
1. 性能测试
2. 缓存命中率监控
3. 数据一致性验证

## 六、风险和备选方案
### 风险
1. **PostgreSQL依赖**：需要额外安装和维护
- 备选：先用SQLite，后续迁移
2. **数据迁移复杂度**：现有数据分散
- 缓解：编写完善的迁移脚本和回滚方案
3. **Redis单点故障**：Redis挂了影响性能
- 缓解：Redis只是缓存，挂了仍可从数据库读取
### 回滚方案
- 保留现有代码分支
- 数据库和缓存作为可选功能
- 降级到内存缓存 + NASA API直连
---
## 七、实施建议
### 推荐方案：**完整实施**
理由：
1. 项目正处于扩展期，早期投入架构收益大
2. PostgreSQL+Redis是成熟方案，风险可控
3. 支持未来功能扩展（用户系统、自定义天体等）
4. 性能提升明显（缓存命中后响应 <50ms）
### 简化方案（如果资源有限）
1. **只用PostgreSQL，不用Redis**
- 降级为两层：内存 → 数据库 → NASA API
- 仍可实现持久化和历史查询
- 性能略低但可接受
2. **只用Redis，不用PostgreSQL**
- 只做缓存，不做持久化
- 适合小规模、不需要历史数据的场景
- 不推荐（失去了数据管理能力）
---
## 八、下一步
确认方案后，我将：
1. **准备安装脚本**：自动化安装PostgreSQL和Redis
2. **生成数据库Schema**：完整的SQL DDL
3. **编写迁移脚本**：将现有数据导入数据库
4. **实现缓存层**：三层缓存逻辑
5. **重构API**：支持数据库查询
6. **迁移静态资源**：统一到后端管理
---

# 缓存预热功能使用说明
## 概述
为了优化首页和时间轴的加载性能，我们实现了**自动缓存预热**功能。
### 功能特性
✅ **启动时自动预热** - 后端启动时自动从数据库加载数据到 Redis
✅ **首页优化** - 预热最近 24 小时的当前位置数据
✅ **时间轴优化** - 预热过去 3 天的历史位置数据
✅ **手动触发** - 提供 API 端点供管理后台调用
---
## 改进内容
### 1. 前端优化
#### 时间轴范围调整
- **调整前**: 90 天（加载慢，容易卡顿）
- **调整后**: 3 天（快速流畅）
**文件**: `frontend/src/App.tsx`
```tsx
// 时间轴范围从 90 天改为 3 天
minDate={new Date(Date.now() - 3 * 24 * 60 * 60 * 1000)} // 3 days ago
// 默认起始日期从 30 天前改为 1 天前
const oneDayAgo = new Date();
oneDayAgo.setDate(oneDayAgo.getDate() - 1);
```
### 2. 后端优化
#### 新增缓存预热服务
**文件**: `backend/app/services/cache_preheat.py`
提供三个核心函数：
1. **`preheat_current_positions()`** - 预热当前位置
- 从数据库加载最近 24 小时的位置数据
- 写入 Redis，TTL 1 小时
- 优化首页首次加载
2. **`preheat_historical_positions(days=3)`** - 预热历史位置
- 从数据库加载过去 N 天的历史数据
- 每天单独缓存，提高缓存命中率
- 写入 Redis，TTL 7 天
- 优化时间轴加载
3. **`preheat_all_caches()`** - 预热所有缓存
- 按优先级执行：当前位置 → 历史位置
- 启动时自动调用
#### 启动时自动预热
**文件**: `backend/app/main.py`
```python
@asynccontextmanager
async def lifespan(app: FastAPI):
# Startup
await redis_cache.connect()
await preheat_all_caches() # 🔥 自动预热
yield
# Shutdown
await redis_cache.disconnect()
```
#### 新增 API 端点
**文件**: `backend/app/api/routes.py`
```python
POST /api/celestial/cache/preheat
```
---
## 使用方法
### 自动预热（推荐）
启动后端服务时会自动执行预热：
```bash
cd backend
python3 app/main.py
```
**预热过程日志**:
```

```
---
### 手动预热（管理后台）
#### 1. 预热所有缓存（当前 + 3天历史）
```bash
curl -X POST "http://localhost:8000/api/celestial/cache/preheat?mode=all"
```
**响应**:
```json
{
"message": "Successfully preheated all caches (current + 3 days historical)"
}
```
---
#### 2. 仅预热当前位置
```bash
curl -X POST "http://localhost:8000/api/celestial/cache/preheat?mode=current"
```
**响应**:
```json
{
"message": "Successfully preheated current positions"
}
```
---
#### 3. 预热历史数据（自定义天数）
预热 7 天历史数据：
```bash
curl -X POST "http://localhost:8000/api/celestial/cache/preheat?mode=historical&days=7"
```
**响应**:
```json
{
"message": "Successfully preheated 7 days of historical positions"
}
```
**参数说明**:
- `mode`: 预热模式
- `all` - 全部（当前 + 历史）
- `current` - 仅当前位置
- `historical` - 仅历史数据
- `days`: 历史数据天数（1-30，默认 3）

| 播放动画 | 450秒（90天 × 5秒） | **0.015秒**（3天 × 5ms） | **30000x** ⚡ |
---
## 验证方法
### 1. 检查 Redis 缓存
启动后端后，检查 Redis 中的缓存键：
```bash
redis-cli keys "positions:*"
```
**预期输出**（4个键）:
```
1) "positions:now:now:1d" # 当前位置
2) "positions:2025-11-26T00:00:00...:2025-11-27T00:00:00...:1d" # 历史：前天
3) "positions:2025-11-27T00:00:00...:2025-11-28T00:00:00...:1d" # 历史：昨天
4) "positions:2025-11-28T00:00:00...:2025-11-29T00:00:00...:1d" # 历史：今天
```
---
### 2. 查看缓存内容
```bash
redis-cli get "positions:now:now:1d"
```
**预期输出**（JSON 格式）:
```json
[
{
"id": "10",
"name": "Sun",
"name_zh": "太阳",
"type": "star",
"description": "太阳，太阳系的中心",
"positions": [
{
"time": "2025-11-29T12:00:00",
"x": 0.0,
"y": 0.0,
"z": 0.0
}
]
},
...
]
```
---
### 3. 检查缓存命中率
打开浏览器控制台，观察 API 请求：
**首次访问（预热后）**:
```
[API Request] GET /api/celestial/positions?step=1d
[API Response] /api/celestial/positions 200 (5ms) ✅ 超快！
```
**后端日志**:
```
INFO: Cache hit (Redis) for recent positions
```
---
### 4. 测试时间轴
1. 打开前端首页
2. 点击"时间轴"按钮
3. 拖动滑块到 1 天前
4. 观察控制台请求时间
**预期**:
- 第一次请求：5ms（Redis 命中）
- 后续请求：<1ms（浏览器缓存）
---
## 故障排查
### 问题 1: 启动时提示 "No recent position"
**原因**: 数据库中没有最近 24 小时的数据
**解决方案**:
1. 手动访问首页触发数据获取
2. 或调用 API 主动获取：
```bash
curl "http://localhost:8000/api/celestial/positions?step=1d"
```
---
### 问题 2: Redis 中没有缓存
**检查步骤**:
1. 确认 Redis 正在运行：
```bash
redis-cli ping
# 应返回: PONG
```
2. 检查后端日志是否有错误：
```bash
grep -i "cache preheat" backend.log
```
3. 手动触发预热：
```bash
curl -X POST "http://localhost:8000/api/celestial/cache/preheat?mode=all"
```
---
### 问题 3: 时间轴仍然很慢
**检查**:
1. 确认时间范围已改为 3 天：
```tsx
minDate={new Date(Date.now() - 3 * 24 * 60 * 60 * 1000)}
```
2. 检查数据库是否有历史数据：
```sql
SELECT COUNT(*) FROM positions
WHERE time >= NOW() - INTERVAL '3 days';
```
3. 重新预热历史数据：
```bash
curl -X POST "http://localhost:8000/api/celestial/cache/preheat?mode=historical&days=3"
```
---
## 数据库依赖
### 预热成功的前提条件
预热功能依赖于数据库中已有的位置数据：
1. **当前位置预热** - 需要 `positions` 表中有最近 24 小时的数据
2. **历史位置预热** - 需要 `positions` 表中有过去 3 天的数据
### 如何初始化数据
#### 方式 1: 自动获取（首次访问）
访问前端首页，会自动查询 NASA API 并保存到数据库。
#### 方式 2: 手动预加载（推荐）
在管理后台实现定时任务，每小时更新一次：
```python
# 伪代码（在管理后台实现）
@scheduler.scheduled_job('interval', hours=1)
async def update_positions():
"""每小时更新一次所有天体的当前位置"""
for body in all_bodies:
positions = horizons_service.get_body_positions(
body.id,
datetime.utcnow(),
datetime.utcnow(),
"1d"
)
position_service.save_positions(body.id, positions, "nasa_horizons")
```
---
## 管理后台集成建议
### 建议功能
1. **缓存状态监控**
- 显示 Redis 中的缓存键数量
- 显示最后预热时间
- 显示缓存命中率
2. **手动预热按钮**
```
[预热当前位置] [预热历史数据(3天)] [预热所有]
```
3. **定时任务配置**
- 每小时更新当前位置
- 每天凌晨预热历史数据
- 每周清理过期缓存
4. **数据完整性检查**
- 检查哪些天体缺少数据
- 检查哪些时间段没有数据
- 自动补全缺失数据
---
## API 文档
### POST /api/celestial/cache/preheat
手动触发缓存预热
**请求参数**:
| 参数 | 类型 | 必填 | 默认值 | 说明 |
|------|------|------|--------|------|
| mode | string | 否 | all | 预热模式：`all`, `current`, `historical` |
| days | integer | 否 | 3 | 历史数据天数（1-30） |
**响应示例**:
```json
{
"message": "Successfully preheated all caches (current + 3 days historical)"
}
```
**错误响应**:
```json
{
"detail": "Invalid mode: xyz. Use 'all', 'current', or 'historical'"
}
```
**使用示例**:
```bash
# 预热所有（默认）
curl -X POST "http://localhost:8000/api/celestial/cache/preheat"
# 仅预热当前位置
curl -X POST "http://localhost:8000/api/celestial/cache/preheat?mode=current"
# 预热 7 天历史数据
curl -X POST "http://localhost:8000/api/celestial/cache/preheat?mode=historical&days=7"
```
---
## 总结
### ✅ 已实现
1. **前端优化**
- 时间轴范围从 90 天改为 3 天
- 默认起始日期从 30 天前改为 1 天前
2. **后端优化**
- 启动时自动预热缓存
- 预热当前位置（最近 24 小时）
- 预热历史位置（过去 3 天）

# 彗星类型实现总结
## 概述
成功为 Cosmo 系统添加了彗星 (comet) 天体类型的完整支持。
## 修改文件清单
### 1. 数据库相关
- ✅ `backend/app/models/db/celestial_body.py` - 数据库模型已支持 'comet' 类型(CheckConstraint)
- 📄 `add_comet_type.sql` - SQL 迁移脚本(如需更新现有数据库约束)
### 2. 后端 API (Backend)
- ✅ `backend/app/models/celestial.py`
- Line 24: 添加 'comet' 到 CelestialBody 的 type Literal
- Line 46: 添加 'comet' 到 BodyInfo 的 type Literal
### 3. 管理平台 (Admin Frontend)
- ✅ `frontend/src/pages/admin/CelestialBodies.tsx`
- Line 264: 添加彗星筛选器选项
- Line 274: 添加类型映射 `comet: '彗星'`
- Line 393: 添加表单中的彗星选项
### 4. 前端可视化 (Frontend)
- ✅ `frontend/src/types/index.ts`
- Line 5: 添加 'comet' 到 CelestialBodyType 类型定义
- ✅ `frontend/src/config/celestialSizes.ts`
- Line 45-50: 添加 COMET_SIZES 配置对象
- Line 65: 在 getCelestialSize 函数中添加 comet 分支
- ✅ `frontend/src/components/ProbeList.tsx`
- Line 2: 导入 Sparkles 图标
- Line 45: 添加 cometList 过滤
- Line 152-163: 添加彗星分组显示
- ✅ `frontend/src/App.tsx`
- Line 99: 在 planets 过滤器中包含 'comet' 类型
## 功能特性
### 1. 数据库层
- 支持 'comet' 作为有效的天体类型
- 自动验证类型约束
### 2. 管理界面
- 可以创建、编辑、删除彗星天体
- 支持彗星类型筛选
- 显示中文名称"彗星"
- 支持上传彗星纹理和资源
### 3. 前端显示
- 彗星在左侧导航栏独立分组显示(带 ✨ Sparkles 图标)
- 彗星使用 CelestialBody 组件渲染
- 默认渲染大小: 0.12 单位(与卫星类似大小)
- 支持为特定彗星配置自定义大小(如 Halley: 0.15)
## 使用指南
### 1. 数据库迁移(如需要)
```bash
psql -h localhost -U postgres -d cosmo -f add_comet_type.sql
```
### 2. 重启服务
确保后端服务重新加载以应用 Pydantic 模型更改:
```bash
# 重启后端服务
```
### 3. 添加彗星示例
在管理平台中:
1. 进入"天体数据管理"
2. 点击"新增"
3. 选择类型:"彗星"
4. 填写信息:
- ID: 例如 "90000034" (哈雷彗星的 JPL ID)
- 英文名: Halley
- 中文名: 哈雷彗星
- 描述: 最著名的周期彗星,约76年回归一次
### 4. 在前端查看
- 彗星会出现在左侧天体导航的"彗星"分组中
- 点击即可聚焦查看
- 在 3D 场景中渲染为小型天体
## 默认配置
### 彗星渲染大小
```typescript
export const COMET_SIZES: Record<string, number> = {
Halley: 0.15, // 哈雷彗星
default: 0.12, // 默认彗星大小
};
```
### 支持的彗星类型特征
- 自动归类到非探测器天体(celestialBodies)
- 使用 CelestialBody 组件渲染(支持纹理贴图)
- 支持轨道显示(如果配置了轨道数据)
- 支持历史位置查询
## 技术细节
### 类型验证链
1. **数据库层**: PostgreSQL CheckConstraint 验证
2. **ORM 层**: SQLAlchemy 模型定义
3. **API 层**: Pydantic Literal 类型验证
4. **前端层**: TypeScript 联合类型
### 数据流
```
管理平台创建彗星
→ API 验证 (Pydantic)
→ 数据库存储 (PostgreSQL)
→ API 返回数据
→ 前端过滤分组
→ 3D 场景渲染
```
## 已解决的问题
### 问题 1: TypeScript 编译错误
**错误**: `This comparison appears to be unintentional because the types 'CelestialBodyType' and '"comet"' have no overlap`
**原因**: `frontend/src/types/index.ts` 中的 CelestialBodyType 缺少 'comet'
**解决**: 添加 'comet' 到类型定义
### 问题 2: 后端 400 Bad Request
**错误**: API 返回 400 Bad Request
**原因**: Pydantic 模型的 Literal 类型不包含 'comet',导致验证失败
**解决**: 在 `backend/app/models/celestial.py` 的两处 Literal 中添加 'comet'
### 问题 3: 前端天体列表缺少彗星
**原因**: `App.tsx` 中的 planets 过滤器未包含 'comet' 类型
**解决**: 在过滤条件中添加 `|| b.type === 'comet'`
## 测试建议
1. **创建测试**:
- 在管理平台创建一个彗星天体
- 验证保存成功
2. **显示测试**:
- 刷新前端页面
- 检查左侧导航是否有"彗星"分组
- 点击彗星,验证能否正常聚焦
3. **API 测试**:
```bash
curl http://localhost:8000/api/celestial/list?body_type=comet
```
## 后续可能的增强
1. **彗星尾巴效果**: 添加粒子系统模拟彗星尾巴
2. **轨道预计算**: 为著名彗星添加轨道数据
3. **周期性管理**: 记录彗星的回归周期
4. **近日点提醒**: 当彗星接近近日点时显示特殊效果
## 完成时间
2025-11-30
## 修改文件数量
- 后端: 2 个文件
- 前端: 5 个文件
- 文档: 2 个文件(SQL + 本总结)

# 数据请求策略优化总结
## 📋 问题发现
### 原始问题
根据最初的规划，为了减少数据量：
1. **时间轴**: 只显示每天 **00:00:00** 的位置数据
2. **首页**: 只显示用户打开时**当前小时**的位置数据
但实际实现中存在以下问题：
- ❌ 时间轴请求了**范围数据**（从 day_start 到 day_end），导致返回多个时间点
- ❌ 首页请求了**最近 24 小时**的所有数据，而不是单个时间点
- ❌ positions 表中存储了大量冗余数据（每天多个时间点）
---
## ✅ 解决方案
### 核心策略
**所有请求都改为单个时间点查询**：`start_time = end_time`
这样 NASA Horizons API 只返回单个时间点的数据，而不是时间范围内的多个点。
---
## 🔧 具体修改
### 1. 前端修改
#### 1.1 首页数据请求 (`frontend/src/hooks/useSpaceData.ts`)
**修改前**:
```tsx
// 无参数请求，后端返回最近 24 小时的数据
const data = await fetchCelestialPositions();
```
**修改后**:
```tsx
// 请求当前小时的单个时间点
const now = new Date();
now.setMinutes(0, 0, 0); // 圆整到小时
const data = await fetchCelestialPositions(
now.toISOString(),
now.toISOString(), // start = end，单个时间点
'1h'
);
```
**API 请求示例**:
```http
GET /api/celestial/positions?start_time=2025-11-29T12:00:00Z&end_time=2025-11-29T12:00:00Z&step=1h
```
**返回数据**: 每个天体 1 个位置点（当前小时）
---
#### 1.2 时间轴数据请求 (`frontend/src/hooks/useHistoricalData.ts`)
**修改前**:
```tsx
const startDate = new Date(date);
const endDate = new Date(date);
endDate.setDate(endDate.getDate() + 1); // +1 天
const data = await fetchCelestialPositions(
startDate.toISOString(), // 2025-01-15T00:00:00Z
endDate.toISOString(), // 2025-01-16T00:00:00Z ❌ 多了1天
'1d'
);
```
**修改后**:
```tsx
// 圆整到 UTC 午夜
const targetDate = new Date(date);
targetDate.setUTCHours(0, 0, 0, 0);
// start = end，只请求午夜这个时间点
const data = await fetchCelestialPositions(
targetDate.toISOString(), // 2025-01-15T00:00:00Z
targetDate.toISOString(), // 2025-01-15T00:00:00Z ✅ 单个时间点
'1d'
);
```
**API 请求示例**:
```http
GET /api/celestial/positions?start_time=2025-01-15T00:00:00Z&end_time=2025-01-15T00:00:00Z&step=1d
```
**返回数据**: 每个天体 1 个位置点（2025-01-15 00:00:00）
---
### 2. 后端缓存预热修改
#### 2.1 当前位置预热 (`backend/app/services/cache_preheat.py`)
**策略变更**:
- **修改前**: 加载最近 24 小时的所有数据
- **修改后**: 只加载当前小时最接近的单个时间点
**实现逻辑**:
```python
# 当前小时
now = datetime.utcnow()
current_hour = now.replace(minute=0, second=0, microsecond=0)
# 搜索窗口: 当前小时 ± 1 小时
start_window = current_hour - timedelta(hours=1)
end_window = current_hour + timedelta(hours=1)
# 找到最接近当前小时的位置
closest_pos = min(
recent_positions,
key=lambda p: abs((p.time - current_hour).total_seconds())
)
```
**Redis Key**:
```
positions:2025-11-29T12:00:00+00:00:2025-11-29T12:00:00+00:00:1h
```
---
#### 2.2 历史位置预热
**策略变更**:
- **修改前**: 每天加载所有时间点的数据
- **修改后**: 每天只加载 00:00:00 这个时间点
**实现逻辑**:
```python
# 目标时间: 当天的午夜 (00:00:00)
target_midnight = target_day.replace(hour=0, minute=0, second=0, microsecond=0)
# 搜索窗口: 午夜 ± 30 分钟
search_start = target_midnight - timedelta(minutes=30)
search_end = target_midnight + timedelta(minutes=30)
# 找到最接近午夜的位置
closest_pos = min(
positions,
key=lambda p: abs((p.time - target_midnight).total_seconds())
)
```
**Redis Key**:
```
positions:2025-11-26T00:00:00+00:00:2025-11-26T00:00:00+00:00:1d
positions:2025-11-27T00:00:00+00:00:2025-11-27T00:00:00+00:00:1d
positions:2025-11-28T00:00:00+00:00:2025-11-28T00:00:00+00:00:1d
```

## 🎯 建议的数据管理策略
### 策略 1: 清空并重建 positions 表（推荐）
**原因**:
- 当前表中可能有大量冗余数据
- 重新开始可以确保数据质量
**步骤**:
```sql
-- 1. 清空 positions 表
TRUNCATE TABLE positions;
-- 2. 清空 nasa_cache 表（可选）
TRUNCATE TABLE nasa_cache;
```
**重新获取数据**:
```bash
# 1. 清空 Redis 缓存
curl -X POST "http://localhost:8000/api/celestial/cache/clear"
# 2. 访问首页触发数据获取（当前小时）
# 打开 http://localhost:5173
# 3. 访问时间轴触发数据获取（过去 3 天的午夜数据）
# 点击"时间轴"按钮
```
---
### 策略 2: 定期更新数据（管理后台实现）
#### 2.1 每小时更新当前位置
```python
@scheduler.scheduled_job('cron', minute=0) # 每小时整点
async def update_current_positions():
"""每小时更新一次所有天体的位置"""
now = datetime.utcnow()
current_hour = now.replace(minute=0, second=0, microsecond=0)
for body in all_bodies:
# 查询 NASA API（单个时间点）
positions = horizons_service.get_body_positions(
body.id,
current_hour,
current_hour, # start = end
"1h"
)
# 保存到数据库
await position_service.save_positions(
body.id, positions, "nasa_horizons", db
)
# 预热缓存
await preheat_current_positions()
```
**数据量**: 20 天体 × 1 条/小时 × 24 小时 = **480 条/天**
---
#### 2.2 每天凌晨更新历史数据（时间轴）
```python
@scheduler.scheduled_job('cron', hour=0, minute=0) # 每天凌晨
async def update_midnight_positions():
"""每天凌晨更新所有天体的午夜位置"""
now = datetime.utcnow()
midnight = now.replace(hour=0, minute=0, second=0, microsecond=0)
for body in all_bodies:
# 查询 NASA API（单个时间点）
positions = horizons_service.get_body_positions(
body.id,
midnight,
midnight, # start = end
"1d"
)
# 保存到数据库
await position_service.save_positions(
body.id, positions, "nasa_horizons", db
)
# 预热历史缓存（3天）
await preheat_historical_positions(days=3)
```
**数据量**: 20 天体 × 1 条/天 = **20 条/天**
---
### 策略 3: 数据清理（可选）
定期清理旧数据以节省存储空间：
```python
@scheduler.scheduled_job('cron', hour=3, minute=0) # 每天凌晨 3 点
async def cleanup_old_positions():
"""清理 30 天前的位置数据"""
cutoff_date = datetime.utcnow() - timedelta(days=30)
# 删除旧数据
await db.execute(
"DELETE FROM positions WHERE time < :cutoff",
{"cutoff": cutoff_date}
)
logger.info(f"Cleaned up positions older than {cutoff_date.date()}")
```
---
## 📈 性能优化效果
### 数据传输量
| 场景 | 修改前 | 修改后 | 优化 |
|------|--------|--------|------|
| 首页加载（20 天体） | ~5-50KB | ~2KB | **75-95%** ⬇️ |
| 时间轴加载（3 天，20 天体） | ~10KB | ~6KB | **40%** ⬇️ |
### 数据库存储
| 周期 | 修改前 | 修改后 | 减少 |
|------|--------|--------|------|
| 每天新增记录 | 不确定（混乱） | 500 条（首页 480 + 时间轴 20） | - |
| 每年总记录数 | 不确定 | ~18万 | - |
---
## ✅ 总结
### 关键改进
1. ✅ **单点查询策略**: 所有请求都改为 `start_time = end_time`
2. ✅ **首页优化**: 只请求当前小时的单个时间点
3. ✅ **时间轴优化**: 只请求每天 00:00:00 的单个时间点
4. ✅ **缓存预热优化**: 预热逻辑匹配单点查询策略
5. ✅ **数据量减少**: 减少 50-96% 的数据传输和存储
### 数据规范
| 场景 | 时间点 | 频率 | 用途 |
|------|--------|------|------|
| **首页** | 每小时整点（XX:00:00） | 每小时更新 1 次 | 显示当前位置 |
| **时间轴** | 每天午夜（00:00:00） | 每天更新 1 次 | 显示历史轨迹 |
### 下一步操作
1. ⚠️ **重启前端和后端**，应用新的请求逻辑
2. ⚠️ **清空 positions 表**（可选但推荐），确保数据干净
3. ✅ **测试首页和时间轴**，验证数据正确性
4. ✅ **在管理后台实现定时任务**，每小时/每天更新数据

# 数据库重复数据问题修复
## 问题描述
在测试过程中发现两个数据库表存在重复数据问题：
### 1. positions 表重复数据
```
120192 399 2025-11-29 05:00:00 0.387... 0.907... -5.638e-05 nasa_horizons 2025-11-29 05:24:23.173
120193 399 2025-11-29 05:00:00 0.387... 0.907... -5.638e-05 nasa_horizons 2025-11-29 05:24:23.175
```
**原因**: 同一个天体在同一时刻有多条位置记录。
### 2. nasa_cache 表重复键错误
```
duplicate key value violates unique constraint "nasa_cache_pkey"
Key (cache_key)=(136199:2025-11-29T05:00:00+00:00:2025-11-29T05:00:00+00:00:1h) already exists.
```
**原因**: 尝试插入已存在的缓存键。
---
## 根本原因
### 并发竞态条件
当多个请求同时查询相同的时间点时：
```
时间线：
T1: 请求 A 查询 body_id=399, time=2025-11-29 05:00:00
T2: 请求 B 查询 body_id=399, time=2025-11-29 05:00:00
T3: 请求 A 检查数据库 -> 未找到 -> 准备插入
T4: 请求 B 检查数据库 -> 未找到 -> 准备插入
T5: 请求 A 插入记录（成功）
T6: 请求 B 插入记录（冲突！）❌
```
### 原始代码问题
#### save_positions (旧版本)
```python
# ❌ 问题：直接添加，不检查是否存在
for pos_data in positions:
position = Position(...)
s.add(position) # 可能重复
await s.commit()
```
#### save_response (旧版本)
```python
# ❌ 问题：SELECT + INSERT 不是原子操作
cache = await s.execute(select(...)).scalar_one_or_none()
if not cache:
cache = NasaCache(...)
s.add(cache) # 可能在 SELECT 和 INSERT 之间被插入
await s.commit()
```
---
## 解决方案
使用 PostgreSQL 的 **UPSERT** 操作（`INSERT ... ON CONFLICT`），将检查和插入变为原子操作。
### 1. 修复 save_positions
**文件**: `backend/app/services/db_service.py`
```python
async def save_positions(...):
from sqlalchemy.dialects.postgresql import insert
for pos_data in positions:
# 使用 UPSERT
stmt = insert(Position).values(
body_id=body_id,
time=pos_data["time"],
x=pos_data["x"],
y=pos_data["y"],
z=pos_data["z"],
...
)
# 遇到冲突时更新
stmt = stmt.on_conflict_do_update(
index_elements=['body_id', 'time'], # 唯一约束
set_={
'x': pos_data["x"],
'y': pos_data["y"],
'z': pos_data["z"],
...
}
)
await s.execute(stmt)
```
**关键点**:
- ✅ `on_conflict_do_update` 原子操作
- ✅ 基于 `(body_id, time)` 唯一约束
- ✅ 冲突时更新而不是报错
---
### 2. 修复 save_response
**文件**: `backend/app/services/db_service.py`
```python
async def save_response(...):
from sqlalchemy.dialects.postgresql import insert
# 使用 UPSERT
stmt = insert(NasaCache).values(
cache_key=cache_key,
body_id=body_id,
start_time=start_naive,
end_time=end_naive,
step=step,
data=response_data,
expires_at=now_naive + timedelta(days=ttl_days)
)
# 遇到冲突时更新
stmt = stmt.on_conflict_do_update(
index_elements=['cache_key'], # 主键
set_={
'data': response_data,
'created_at': now_naive,
'expires_at': now_naive + timedelta(days=ttl_days)
}
).returning(NasaCache)
result = await s.execute(stmt)
cache = result.scalar_one()
```
**关键点**:
- ✅ `on_conflict_do_update` 原子操作
- ✅ 基于 `cache_key` 主键
- ✅ 冲突时更新数据和过期时间
---
## 数据库唯一约束验证
确保数据库表有正确的唯一约束：
### positions 表
```sql
-- 检查唯一约束
SELECT constraint_name, constraint_type
FROM information_schema.table_constraints
WHERE table_name = 'positions'
AND constraint_type = 'UNIQUE';
-- 如果没有，创建唯一约束
ALTER TABLE positions
ADD CONSTRAINT positions_body_time_unique
UNIQUE (body_id, time);
```
### nasa_cache 表
```sql
-- 检查主键
SELECT constraint_name, constraint_type
FROM information_schema.table_constraints
WHERE table_name = 'nasa_cache'
AND constraint_type = 'PRIMARY KEY';
-- cache_key 应该是主键，已有唯一约束
```
---
## 清理现有重复数据
执行 SQL 脚本清理重复数据：
```bash
psql -U postgres -d cosmo -f backend/scripts/cleanup_duplicates.sql
```
**脚本功能**:
1. 删除 positions 表中的重复记录（保留最新的）
2. 删除 nasa_cache 表中的重复记录（保留最新的）
3. 验证清理结果
---
## 验证修复效果
### 1. 重启后端服务
```bash
cd backend
python3 app/main.py
```
### 2. 测试并发请求
在两个终端同时执行相同的请求：
```bash
# 终端 1
curl "http://localhost:8000/api/celestial/positions?start_time=2025-11-29T12:00:00Z&end_time=2025-11-29T12:00:00Z&step=1h"
# 终端 2（同时执行）
curl "http://localhost:8000/api/celestial/positions?start_time=2025-11-29T12:00:00Z&end_time=2025-11-29T12:00:00Z&step=1h"
```
**预期结果**:
- ✅ 两个请求都成功返回
- ✅ 没有重复数据错误
- ✅ 数据库中只有一条记录
### 3. 验证数据库
```sql
-- 检查是否还有重复
SELECT body_id, time, COUNT(*)
FROM positions
GROUP BY body_id, time
HAVING COUNT(*) > 1;
-- 应返回 0 行
SELECT cache_key, COUNT(*)
FROM nasa_cache
GROUP BY cache_key
HAVING COUNT(*) > 1;
-- 应返回 0 行
```
---
## 性能优势
### UPSERT vs SELECT + INSERT
| 操作 | SELECT + INSERT | UPSERT |
|------|----------------|--------|
| 数据库往返次数 | 2 次（SELECT + INSERT） | 1 次 |
| 锁定时间 | 长（两个操作） | 短（单个操作） |
| 并发安全 | ❌ 不安全 | ✅ 安全 |
| 性能 | 慢 | 快 |
### 示例
假设 10 个并发请求：
**旧方法**:
- 10 个 SELECT（可能都返回 NULL）
- 10 个 INSERT 尝试（9 个失败）
- 总数据库操作：20 次
**新方法**:
- 10 个 UPSERT（1 个 INSERT，9 个 UPDATE）
- 总数据库操作：10 次
- 性能提升：**50%** ⚡
---
## 总结
### ✅ 已修复
1. **positions 表**: 使用 UPSERT 避免重复插入
2. **nasa_cache 表**: 使用 UPSERT 避免重复插入
3. **并发安全**: 原子操作避免竞态条件
4. **性能提升**: 减少数据库往返次数
### 🎯 后续建议
1. **定期清理**: 每天检查并清理潜在的重复数据
2. **监控告警**: 监控唯一约束冲突次数
3. **压力测试**: 测试高并发场景下的数据一致性

# 轨道系统优化完成指南
## ✅ 已完成的工作
### 1. **数据库层**
- ✅ 创建了 `orbits` 表（已执行SQL）
- ✅ 创建了 `Orbit` ORM 模型 (`backend/app/models/db/orbit.py`)
### 2. **后端服务层**
- ✅ 创建了 `OrbitService` (`backend/app/services/orbit_service.py`)
- 轨道数据的增删改查
- 自动从 NASA Horizons 生成轨道数据
- 智能采样点计算（短周期=每天，长周期=每月）
### 3. **API 端点**
- ✅ `GET /api/celestial/orbits` - 获取所有轨道数据
- ✅ `POST /api/celestial/admin/orbits/generate` - 生成轨道数据
- ✅ `DELETE /api/celestial/admin/orbits/{body_id}` - 删除轨道
### 4. **前端组件**
- ✅ 创建了统一的 `OrbitRenderer` 组件 (`frontend/src/components/OrbitRenderer.tsx`)
- ✅ 修改了 `Scene.tsx`，使用新的轨道渲染组件
- ✅ 移除了旧的 `Orbit.tsx` 和 `DwarfPlanetOrbits.tsx` 的使用
---
## 🚀 使用方法
### 步骤 1: 生成轨道数据
**方式 A: 生成所有天体的轨道（推荐）**
```bash
curl -X POST "http://localhost:8000/api/celestial/admin/orbits/generate"
```
这会为所有行星和矮行星生成轨道数据（约需要 2-5 分钟，取决于网络和 NASA API 速度）。
**方式 B: 只生成特定天体的轨道**
```bash
# 只生成地球和冥王星的轨道
curl -X POST "http://localhost:8000/api/celestial/admin/orbits/generate?body_ids=399,999"
```
**进度监控**：
查看后端日志，你会看到类似输出：
```
🌌 Generating orbit for 地球 (period: 365.3 days)
📊 Sampling 120 points (every 3 days)
✅ Retrieved 120 orbital points
💾 Saved orbit for 地球
```
---
### 步骤 2: 验证数据
**检查生成的轨道数据**：
```bash
curl "http://localhost:8000/api/celestial/orbits"
```
**预期响应**：
```json
{
"orbits": [
{
"body_id": "399",
"body_name": "Earth",
"body_name_zh": "地球",
"points": [
{"x": 1.0, "y": 0.0, "z": 0.0},
{"x": 0.99, "y": 0.05, "z": 0.01},
...
],
"num_points": 120,
"period_days": 365.25,
"color": "#4A90E2",
"updated_at": "2025-11-29T12:00:00"
},
...
]
}
```
---
### 步骤 3: 前端查看
1. **启动前端** (如果还没启动):
```bash
cd frontend
yarn dev
```
2. **打开浏览器**: http://localhost:5173
3. **预期效果**:
- ✅ 所有行星轨道显示为真实椭圆轨道（不再是圆形）
- ✅ 矮行星轨道完整显示（冥王星、阋神星等）
- ✅ 轨道显示不同颜色
- ✅ 加载速度快（<1秒）
---
## 📊 轨道数据详情
### 采样策略
| 天体类型 | 轨道周期 | 采样间隔 | 点数 |
|---------|---------|---------|------|
| 水星 | 88天 | 每天 | 88 |
| 地球 | 365天 | 每3天 | 120 |
| 木星 | 11.86年 | 每18天 | 240 |
| 土星 | 29.46年 | 每36天 | 300 |
| 冥王星 | 248年 | 每248天 | 365 |
| 阋神星 | 557年 | 每557天 | 365 |
### 数据量
- **单个行星**: ~3-10 KB
- **所有行星+矮行星**: ~100-200 KB
- **首次加载**: 需要2-5分钟生成
- **后续加载**: <1秒（从数据库读取）
---
## 🔧 后续维护
### 更新轨道数据
轨道数据会随着时间推移略有变化（行星摄动），建议每月更新一次：
```bash
# 重新生成所有轨道
curl -X POST "http://localhost:8000/api/celestial/admin/orbits/generate"
```
### 删除轨道数据
```bash
# 删除特定天体的轨道
curl -X DELETE "http://localhost:8000/api/celestial/admin/orbits/399"
```
### 添加新天体
如果在 `celestial_bodies` 表中添加了新天体：
1. 在 `routes.py` 的 `ORBITAL_PERIODS` 字典中添加轨道周期
2. 在 `DEFAULT_COLORS` 字典中添加颜色
3. 运行生成命令
---
## 🎯 优势对比
### 之前（旧实现）
- ❌ 行星：数学模拟的圆形轨道（不准确）
- ❌ 矮行星：每次加载请求10年数据（慢）
- ❌ 数据量大：每次请求 ~400 KB
- ❌ 加载时间：5-10秒
- ❌ 轨道不完整：只显示部分周期
### 现在（新实现）
- ✅ 所有天体：真实NASA数据
- ✅ 预计算存储：快速加载
- ✅ 数据量优化：~100-200 KB总量
- ✅ 加载时间：<1秒
- ✅ 完整轨道：显示整个周期
---
## 🐛 故障排查
### 问题 1: 轨道不显示
**检查**：
```bash
curl "http://localhost:8000/api/celestial/orbits"
```
**如果返回空数组**：
```bash
# 生成轨道数据
curl -X POST "http://localhost:8000/api/celestial/admin/orbits/generate"
```
### 问题 2: 后端报错 "No orbital period defined"
**原因**: 天体ID不在 `ORBITAL_PERIODS` 字典中
**解决**: 在 `routes.py` 中添加该天体的轨道周期
### 问题 3: 生成失败 "Failed to fetch from NASA"
**原因**: NASA Horizons API 响应慢或超时
**解决**:
1. 等待几分钟后重试
2. 或单独生成每个天体：
```bash
curl -X POST "http://localhost:8000/api/celestial/admin/orbits/generate?body_ids=399"
```

# Redis 键结构概览
## Redis 中主要存在以下几类键（Key Prefix）：
* user:tokens:* (对应您提到的 token 和 user 相关的)
* positions:* (对应 positions)
* cosmo:danmaku:stream (留言板)
## Positions (位置数据) 的机制
在 backend/app/services/db_service.py 和 redis_cache.py 中体现了位置数据的缓存策略。
`positions:{start_time}:{end_time}:{step}` (String/JSON 类型)
* 目的：缓存前端请求的“天体位置列表”数据。
* 机制 (多级缓存 L1/L2/L3)：
1. 请求到来：当 API 收到 /celestial/positions 请求时，它会根据查询参数（开始时间、结束时间、步长）生成一个唯一的 Cache Key。
2. L2 (Redis)：首先检查 Redis 中是否有这个 Key。
* 命中：直接返回 Redis 中的 JSON 数据。这是最快的，通常在毫秒级。
* 未命中：继续向下查询。
3. L3 (Database/Horizons)：如果 Redis 没有，系统会去 PostgreSQL 数据库查询（预取的数据），或者调用 NASA Horizons API 获取实时数据。
4. 回写：获取到数据后，系统会将结果序列化为 JSON，写入 Redis，并设置过期时间（TTL，例如 1 小时或 7 天）。
* 特点：
* 查询驱动：只有被请求过的数据才会被缓存。
* 预热 (Preheat)：系统有 preheat 机制，会在启动时自动计算未来一段时间（如 30 天）的位置数据并写入 Redis，确保用户访问时是秒开的。
## Cosmo / danmaku (留言板)
* `cosmo:danmaku:stream` (Sorted Set 类型):
* 这是我们刚刚实现的留言板/弹幕功能。
* 使用 Sorted Set，以时间戳（Timestamp）作为 Score。
* 这允许我们高效地执行“获取最近 5 分钟的消息” (ZRANGEBYSCORE) 和“清理 24 小时前的消息” (ZREMRANGEBYSCORE) 操作。
## 总结架构图
| 键前缀 (Key Prefix) | 类型 (Type) | 用途 (Purpose) | 有效期 (TTL) |
|------|--------------|-------------|------|
| user:tokens:{uid} | Set | 存该用户所有活动的 JWT Token，用于多端登录和注销。 | 随 Token 过期 |
| positions:{args} | String (JSON) | API 响应缓存。存前端需要的天体坐标数组。 | 1小时 (实时) / 7天 (历史) |
| cosmo:danmaku:stream | ZSet | 留言板消息流。按时间排序，自动过期。 | 24 小时 (可配) |

# 可视化问题分析与解决方案
## 问题 1: 探测器/月球的视觉偏移导致距离失真
### 🚨 问题描述
当前实现中，为了避免探测器和月球与行星重合，使用了 `renderPosition.ts` 中的智能偏移逻辑：
```typescript
// renderPosition.ts:116-127
if (realDistance < 0.01) {
// 月球或表面探测器 - 固定偏移
visualOffset = planetVisualRadius + 2.0; // 距离表面 2 个单位
} else if (realDistance < 0.05) {
visualOffset = planetVisualRadius + 3.0;
} else {
visualOffset = planetVisualRadius + 4.0;
}
```
**问题**：
- ❌ 月球真实距离地球 0.0026 AU（38万公里）
- ❌ 但在视觉上被推到距离地球表面 2 个缩放单位
- ❌ 用户无法判断月球与太阳的真实距离关系
- ❌ 探测器的真实轨道距离完全失真
**影响范围**：
- 月球（Earth's Moon）
- 火星探测器（Perseverance, Curiosity）
- 木星探测器（Juno）
- 土星探测器（Cassini）
---
## 问题 2: 矮行星轨道数据加载量过大
### 🚨 问题描述
当前 `DwarfPlanetOrbits.tsx` 的实现：
```typescript
// DwarfPlanetOrbits.tsx:61-72
const startDate = new Date('2020-01-01');
const endDate = new Date('2030-01-01');
const response = await fetch(
`http://localhost:8000/api/celestial/positions?` +
`body_ids=${bodyIds}&` +
`start_time=${startDate.toISOString()}&` +
`end_time=${endDate.toISOString()}&` +
`step=30d` // 10 年 = 120 个点/天体
);
```
**问题**：
- ❌ 矮行星公转周期：冥王星 248 年，阋神星 557 年
- ❌ 10 年数据只能显示公转轨道的 4-18%
- ❌ 需要请求完整轨道周期数据（248-557 年）
- ❌ 数据量巨大：冥王星完整轨道 = 248 年 × 12 月 = 2976 个点
- ❌ 首次加载会触发大量 NASA API 调用
**矮行星轨道周期**：
| 天体 | 公转周期 | 完整轨道点数（30天/点） | 数据量 |
|------|----------|----------------------|--------|
| 冥王星 | 248 年 | 2,976 点 | 71 KB |
| 阋神星 | 557 年 | 6,684 点 | 160 KB |
| 妊神星 | 285 年 | 3,420 点 | 82 KB |
| 鸟神星 | 309 年 | 3,708 点 | 89 KB |
| 谷神星 | 4.6 年 | 55 点 | 1.3 KB |
**总数据量**：~403 KB（单次请求）

## 解决方案对比
### 方案 1: 视觉偏移 + 真实距离提示 ⭐⭐⭐
**策略**：保持当前视觉偏移，但在 UI 上明确标注真实距离。
**实现**：
1. **在天体详情卡片中显示真实距离**：
```typescript
// ProbeList.tsx 或 CelestialBody 详情
{hasOffset && (
<div className="text-yellow-400 text-xs">
<span>⚠️ 视觉位置已调整便于观察</span>
<span>真实距离: {realDistance.toFixed(4)} AU</span>
<span>约 {(realDistance * 149597870.7).toFixed(0)} 千米</span>
</div>
)}
```
2. **添加真实轨道线（虚线）**：
```typescript
// 在 Probe.tsx 中添加真实轨道路径
{hasOffset && (
<Line
points={[
new Vector3(realPos.x, realPos.y, realPos.z), // 真实位置
new Vector3(visualPos.x, visualPos.y, visualPos.z) // 视觉位置
]}
color="yellow"
lineWidth={1}
dashed
dashSize={0.1}
gapSize={0.05}
/>
)}
```
**优点**：
- ✅ 保持当前的视觉清晰度
- ✅ 通过文字和虚线提示真实位置
- ✅ 实现简单，改动小
**缺点**：
- ⚠️ 用户仍然无法直观看到真实距离
- ⚠️ 需要额外的 UI 提示
---
### 方案 2: 移除视觉偏移，优化缩放算法 ⭐⭐⭐⭐⭐（推荐）
**策略**：改进距离缩放算法，让近距离天体也能清晰显示，无需偏移。
**核心思路**：
- 在 **极近距离**（< 0.01 AU）使用**对数缩放**
- 让月球和探测器保持真实方向，但有足够的视觉间隔
**实现**：
```typescript
// scaleDistance.ts - 新增超近距离缩放
export function scaleDistance(distanceInAU: number): number {
// Ultra-close region (< 0.001 AU): extreme expansion for moons/probes
if (distanceInAU < 0.001) {
// 对数缩放：0.0001 AU → 0.1, 0.001 AU → 0.5
return 0.1 + Math.log10(distanceInAU + 0.0001) * 0.4;
}
// Very close region (0.001-0.01 AU): strong expansion
if (distanceInAU < 0.01) {
// 0.001 AU → 0.5, 0.01 AU → 1.5
return 0.5 + (distanceInAU - 0.001) * 100;
}
// Close region (0.01-0.1 AU): moderate expansion
if (distanceInAU < 0.1) {
return 1.5 + (distanceInAU - 0.01) * 20;
}
// Inner solar system (0.1-2 AU): expand by 3x
if (distanceInAU < 2) {
return 3.3 + (distanceInAU - 0.1) * 3;
}
// Middle region (2-10 AU): normal scale
if (distanceInAU < 10) {
return 9 + (distanceInAU - 2) * 1.5;
}
// Outer solar system (10-50 AU): compressed
if (distanceInAU < 50) {
return 21 + (distanceInAU - 10) * 0.5;
}
// Very far (> 50 AU): heavily compressed
return 41 + (distanceInAU - 50) * 0.2;
}
```
**修改 renderPosition.ts**：
```typescript
// 移除视觉偏移逻辑，直接使用缩放位置
export function calculateRenderPosition(
body: CelestialBody,
allBodies: CelestialBody[]
): { x: number; y: number; z: number } {
const pos = body.positions[0];
if (!pos) {
return { x: 0, y: 0, z: 0 };
}
// 直接使用改进的缩放算法，无需偏移
const scaled = scalePosition(pos.x, pos.y, pos.z);
return { x: scaled.x, y: scaled.y, z: scaled.z };
}
```
**效果对比**：
| 天体 | 真实距离 | 旧缩放 | 新缩放 | 改进 |
|------|----------|--------|--------|------|
| 月球 | 0.0026 AU | 0.0078 | 0.76 | **98倍** |
| 火星探测器 | ~1.5 AU | 4.5 | 7.5 | 更清晰 |
| 地球 | 1.0 AU | 3.0 | 5.7 | 更合理 |
**优点**：
- ✅ 保持真实的空间关系
- ✅ 月球和探测器仍然可见（足够大）
- ✅ 用户可以直观理解距离
- ✅ 无需 UI 提示
**缺点**：
- ⚠️ 需要调整缩放参数，可能需要多次调试
---
### 方案 3: 双模式切换（真实模式 vs 演示模式）⭐⭐⭐⭐
**策略**：提供两种显示模式，用户可以切换。
**实现**：
```typescript
// App.tsx
const [visualMode, setVisualMode] = useState<'realistic' | 'demo'>('demo');
// Header.tsx 添加切换按钮
<button onClick={() => setVisualMode(mode === 'realistic' ? 'demo' : 'realistic')}>
{visualMode === 'realistic' ? '真实距离' : '演示模式'}
</button>
// renderPosition.ts
export function calculateRenderPosition(
body: CelestialBody,
allBodies: CelestialBody[],
mode: 'realistic' | 'demo'
): Position {
if (mode === 'realistic') {
// 使用改进的缩放，无偏移
return scalePosition(pos.x, pos.y, pos.z);
} else {
// 使用视觉偏移
return calculateDemoPosition(body, allBodies);
}
}
```
**优点**：
- ✅ 灵活性最高
- ✅ 满足不同用户需求
- ✅ 教育价值高
**缺点**：
- ⚠️ 实现复杂度较高
- ⚠️ 需要维护两套逻辑
---
## 矮行星轨道问题解决方案
### 方案 A: 预计算并存储完整轨道数据 ⭐⭐⭐⭐⭐（推荐）
**策略**：按照 `ORBIT_OPTIMIZATION.md` 的方案 1A 实现。
**实施步骤**：
1. **创建 orbits 表**（已在 ORBIT_OPTIMIZATION.md 中定义）
2. **后端管理接口生成轨道**：
```python
# app/api/routes.py
@router.post("/admin/orbits/generate")
async def generate_dwarf_planet_orbits(db: AsyncSession = Depends(get_db)):
"""为矮行星生成完整轨道数据"""
dwarf_planets = await celestial_body_service.get_bodies_by_type(db, "dwarf_planet")
orbital_periods = {
"999": 248, # 冥王星
"136199": 557, # 阋神星
"136108": 285, # 妊神星
"136472": 309, # 鸟神星
"1": 4.6, # 谷神星
}
for planet in dwarf_planets:
period_years = orbital_periods.get(planet.id, 250)
# 计算采样点数：完整周期，每 30 天一个点
num_points = min(int(period_years * 365 / 30), 1000) # 最多 1000 点
# 查询 NASA Horizons
start = datetime.utcnow()
end = start + timedelta(days=period_years * 365)
step_days = int(period_years * 365 / num_points)
positions = await horizons_service.get_body_positions(
planet.id,
start,
end,
f"{step_days}d"
)
# 保存到 orbits 表
await orbit_service.save_orbit(
planet.id,
[{"x": p.x, "y": p.y, "z": p.z} for p in positions],
num_points,
period_years * 365
)
return {"message": f"Generated {len(dwarf_planets)} orbits"}
```
3. **前端从 API 读取**：
```typescript
// DwarfPlanetOrbits.tsx - 简化版
useEffect(() => {
const fetchOrbits = async () => {
// 直接从后端读取预存的轨道数据
const response = await fetch('http://localhost:8000/api/celestial/orbits?body_type=dwarf_planet');
const data = await response.json();
const orbitData = data.orbits.map((orbit: any) => ({
bodyId: orbit.body_id,
points: orbit.points.map((p: any) => {
const scaled = scalePosition(p.x, p.y, p.z);
return new THREE.Vector3(scaled.x, scaled.z, scaled.y);
}),
color: orbit.color || getDefaultColor(orbit.body_name)
}));
setOrbits(orbitData);
};
fetchOrbits();
}, []);
```
**优点**：
- ✅ 完整准确的轨道
- ✅ 前端加载快（<1秒）
- ✅ 无需实时 NASA API 调用
- ✅ 数据量可接受（总共 ~400 KB）
**缺点**：
- ⚠️ 需要数据库迁移
- ⚠️ 首次生成需要时间（一次性）
---
### 方案 B: 使用数学模拟轨道 ⭐⭐⭐⭐
**策略**：基于轨道六要素（orbital elements）数学计算。
**实现**：
```typescript
// EllipticalOrbit.tsx
interface OrbitalElements {
a: number; // 半长轴 (AU)
e: number; // 离心率
i: number; // 轨道倾角 (度)
omega: number; // 升交点黄经 (度)
w: number; // 近日点幅角 (度)
M0: number; // 平近点角 (度)
period: number; // 轨道周期 (天)
}
// 冥王星轨道要素（来自 NASA JPL）
const PLUTO_ELEMENTS: OrbitalElements = {
a: 39.48,
e: 0.2488,
i: 17.16,
omega: 110.30,
w: 113.77,
M0: 14.53,
period: 90560
};
function generateOrbitPoints(elements: OrbitalElements, numPoints = 360): Vector3[] {
const points: Vector3[] = [];
for (let i = 0; i <= numPoints; i++) {
const M = (i / numPoints) * 2 * Math.PI; // 平近点角
// 求解开普勒方程得到偏近点角 E
let E = M;
for (let j = 0; j < 10; j++) {
E = M + elements.e * Math.sin(E);
}
// 计算真近点角
const v = 2 * Math.atan(
Math.sqrt((1 + elements.e) / (1 - elements.e)) * Math.tan(E / 2)
);
// 计算轨道平面坐标
const r = elements.a * (1 - elements.e * Math.cos(E));
const x_orb = r * Math.cos(v);
const y_orb = r * Math.sin(v);
// 旋转到黄道坐标系
const point = rotateToEcliptic(x_orb, y_orb, 0, elements);
const scaled = scalePosition(point.x, point.y, point.z);
points.push(new Vector3(scaled.x, scaled.z, scaled.y));
}
return points;
}
```
**轨道要素来源**：
- NASA JPL Small-Body Database: https://ssd.jpl.nasa.gov/sbdb.cgi
- 可以从后端 `celestial_bodies` 表的 `orbital_elements` 字段读取
**优点**：
- ✅ 不需要网络请求
- ✅ 瞬时生成
- ✅ 数学上准确
- ✅ 可以显示任意时间的轨道
**缺点**：
- ⚠️ 实现复杂（轨道力学）
- ⚠️ 不考虑摄动（其他行星引力影响）
- ⚠️ 需要获取和验证轨道要素
---
### 方案 C: 混合方案 - 谷神星用真实数据，其他用模拟 ⭐⭐⭐
**策略**：
- **谷神星**（4.6 年周期）：使用真实数据（55 点，1.3 KB）
- **冥王星、阋神星等**（>200 年周期）：使用数学模拟
**理由**：
- 谷神星周期短，数据量小
- 长周期矮行星用数学模拟足够准确
**实现**：
```typescript
// DwarfPlanetOrbits.tsx
const fetchOrbits = async () => {
// 只请求谷神星（Ceres）的真实数据
const ceresOrbit = await fetchRealOrbit('1', 5); // 5 年数据
// 其他矮行星用数学模拟
const plutoOrbit = generateOrbitPoints(PLUTO_ELEMENTS);
const erisOrbit = generateOrbitPoints(ERIS_ELEMENTS);
// ...
};
```
**优点**：
- ✅ 平衡准确性和性能
- ✅ 减少数据加载
- ✅ 关键天体（谷神星）使用真实数据
**缺点**：
- ⚠️ 需要维护两套逻辑
---
## 推荐实施方案
### 问题 1（探测器偏移）：**方案 2 - 优化缩放算法**
- 实施优先级：**高**
- 预计工时：2-3 小时
- 风险：低（可以逐步调整参数）
### 问题 2（矮行星轨道）：**方案 A - 预计算轨道数据**
- 实施优先级：**中**
- 预计工时：4-6 小时（包括数据库迁移）
- 风险：低（数据生成是一次性的）
**备选方案**：如果时间紧张，可以先用 **方案 B（数学模拟）** 作为临时解决方案。
---
## 实施步骤（建议顺序）
### 第一阶段：修复探测器偏移问题
1. 修改 `scaleDistance.ts`，添加超近距离缩放
2. 简化 `renderPosition.ts`，移除偏移逻辑
3. 测试月球、火星探测器等的显示效果
4. 微调缩放参数
### 第二阶段：优化矮行星轨道
1. 创建 `orbits` 表（数据库迁移）
2. 实现后端轨道生成 API
3. 在管理后台添加"生成轨道"按钮
4. 修改 `DwarfPlanetOrbits.tsx` 从 API 读取
5. 首次生成所有矮行星轨道数据
---
## 后续优化建议
1. **添加缩放级别指示器**：
- 显示当前视图的缩放比例
- "内太阳系视图（0-2 AU，放大 3x）"
2. **添加距离标尺**：
- 在场景中显示距离参考线
- "1 AU = X 屏幕单位"
3. **轨道数据自动更新**：
- 定期（每月）重新生成轨道数据
- 保持数据时效性

-- SQL Migration: Add 'comet' type support to celestial_bodies table
--
-- Purpose: Enable comet celestial body type in the database
--
-- Note: The CheckConstraint in the ORM model (celestial_body.py line 37) already includes 'comet',
-- but if the database was created before this was added, we need to update the constraint.

-- Instructions:
-- 1. Check if the constraint already includes 'comet':
-- SELECT conname, pg_get_constraintdef(oid)
-- FROM pg_constraint
-- WHERE conrelid = 'celestial_bodies'::regclass AND conname = 'chk_type';
--
-- 2. If 'comet' is NOT in the constraint, run the following migration:
-- Step 1: Drop the existing constraint
ALTER TABLE celestial_bodies DROP CONSTRAINT IF EXISTS chk_type;
-- Step 2: Recreate the constraint with 'comet' included
ALTER TABLE celestial_bodies
ADD CONSTRAINT chk_type
CHECK (type IN ('star', 'planet', 'moon', 'probe', 'comet', 'asteroid', 'dwarf_planet', 'satellite'));
-- Step 3: Verify the constraint was updated successfully
SELECT conname, pg_get_constraintdef(oid)
FROM pg_constraint
WHERE conrelid = 'celestial_bodies'::regclass AND conname = 'chk_type';
