feat: Initial CBPOA commit — 武汉儿童呼吸疾病风险评估系统
Context: Build a spatial risk assessment system correlating air quality data with children's respiratory disease incidence across Wuhan. Approach: FastAPI backend serving PostGIS spatial queries, React frontend with Deck.gl maps, and a PyTorch SpatialTemporalGCN pipeline for multi-day (1d/3d/7d) risk prediction. Changes: - backend/ — FastAPI API with auth (JWT), alerts, risk analysis, geocoded case data, grid statistics, and report endpoints - frontend/ — React dashboard with interactive risk maps, alert monitoring, district comparison charts, and timeline player - models/ — SpatialTemporalGCN model with trained weights and ONNX export for inference - scripts/ — ETL pipeline for weather + medical data, grid generation, feature engineering, training, and daily inference - deploy/ — Docker Compose configs for backend, frontend, and MLflow - docs/ — API docs, deployment guide, user guide, and code review Impact: Enables spatial risk visualization, alert monitoring, and ML-driven health risk forecasting for environmental health teams.

### 4. Security Review
|
||||
|
||||
| Check | Status | Notes |
|
||||
|-------|--------|-------|
|
||||
| No hardcoded secrets | ✅ PASS | Using `.env` file |
|
||||
| SQL injection prevention | ✅ PASS | Using SQLAlchemy ORM |
|
||||

|
||||
| CORS configured | ✅ PASS | Limited to localhost in dev |
|
||||
| Non-root Docker user | ✅ PASS | Backend uses `appuser` |
|
||||
|
||||
### 5. Performance Review
|
||||
|
||||
| Optimization | Status | Impact |
|
||||
|--------------|--------|--------|
|
||||
| Feature caching (LRU) | ✅ Implemented | Reduces redundant computation |
|
||||
| Batch processing | ✅ Implemented | Handles 10K grids/batch |
|
||||
| API response caching | ✅ Implemented | 30s TTL |
|
||||
| Lazy loading | ⚠️ Partial | Grid data loaded on-demand |
|
||||
|
||||
### 6. Documentation Review
|
||||
|
||||
| Document | Completeness | Quality |
|
||||
|----------|-------------|---------|

|
||||
| Deployment Guide | ✅ 100% | Step-by-step instructions |
|
||||
| User Manual | ✅ 100% | Detailed with screenshots |
|
||||
| Code Comments | ⚠️ 70% | Some files lack docstrings |
|
||||
|
||||
### 7. Test Coverage
|
||||
|
||||
| Test Type | Status | Coverage |
|
||||
|-----------|--------|----------|
|
||||
| Unit Tests | ❌ NOT IMPLEMENTED | 0% |
|
||||
| Integration Tests | ❌ NOT IMPLEMENTED | 0% |
|
||||
| E2E Tests | ✅ IMPLEMENTED | API + Frontend flows |
|
||||
|
||||
### 8. Recommendations
|
||||
|
||||
#### High Priority
|
||||
1. **Add unit tests** for critical backend logic (feature generation, predictions)
|
||||
2. **Add integration tests** for API endpoints
|
||||
3. **Implement CI/CD pipeline** for automated testing
|
||||
|
||||
#### Medium Priority
|
||||
4. Add docstrings to all public functions
|
||||
5. Implement comprehensive error handling
|
||||
6. Add request validation middleware
|
||||
|
||||
#### Low Priority
|
||||
7. Add TypeScript strict mode
|
||||
8. Add Python type hints to all functions
|
||||
9. Implement logging framework
|
||||
|
||||
### 9. Final Verdict
|
||||
|
||||
**Overall Status**: ✅ READY FOR DEPLOYMENT (with caveats)
|
||||
|
||||
**Strengths**:
|
||||
- Clean, modular code structure
|
||||
- Comprehensive documentation
|
||||
- Docker-based deployment ready
|
||||
- Performance optimizations in place
|
||||
|
||||
**Weaknesses**:
|
||||
- Limited test coverage (E2E only)
|
||||
- Some TypeScript strictness issues
|
||||
- Missing CI/CD pipeline
|
||||
|
||||
**Deployment Recommendation**:
|
||||
- ✅ **APPROVE** for staging/development deployment
|
||||
- ⚠️ **CONDITIONAL** for production (requires unit tests)

### 数据持久化
|
||||
|
||||
PostgreSQL 数据存储在 Docker volume `postgres_data` 中:
|
||||
|
||||
```bash
|
||||
# 查看 volume
|
||||
docker volume ls | grep postgres
|
||||
|
||||
# 备份数据
|
||||
docker run --rm -v ca_deploy_postgres_data:/data -v $(pwd):/backup alpine tar czf /backup/postgres-backup.tar.gz -C /data .
|
||||
|
||||
# 恢复数据
|
||||
docker run --rm -v ca_deploy_postgres_data:/data -v $(pwd):/backup alpine tar xzf /backup/postgres-backup.tar.gz -C /data
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 初始化数据库
|
||||
|
||||
### 1. 创建 grids 表
|
||||
|
||||
```bash
|
||||
docker compose exec postgres psql -U wuhan_user -d wuhan_disease -f /docker-entrypoint-initdb.d/init.sql
|
||||
```
|
||||
|
||||
或手动执行:
|
||||
|
||||
```sql
|
||||
CREATE EXTENSION IF NOT EXISTS postgis;
|
||||
|
||||
CREATE TABLE IF NOT EXISTS grids (
|
||||
grid_id VARCHAR(20) PRIMARY KEY,
|
||||
geometry GEOMETRY(POLYGON, 4326) NOT NULL,
|
||||
center_lat DOUBLE PRECISION NOT NULL,
|
||||
center_lon DOUBLE PRECISION NOT NULL,
|
||||
district VARCHAR(50),
|
||||
dem DOUBLE PRECISION,
|
||||
population_density DOUBLE PRECISION,
|
||||
created_at TIMESTAMP DEFAULT NOW()
|
||||
);
|
||||
|
||||
CREATE INDEX idx_grids_geometry ON grids USING GIST (geometry);
|
||||
CREATE INDEX idx_grids_district ON grids (district);
|
||||
```
|
||||
|
||||
### 2. 导入网格数据
|
||||
|
||||
```bash
|
||||
# 从容器外复制数据到容器
|
||||
docker cp processed/grid_100m_index.parquet $(docker compose ps -q postgres):/tmp/grid_data.parquet
|
||||
|
||||
# 在容器内导入
|
||||
docker compose exec postgres python3 << 'EOF'
|
||||
import pandas as pd
|
||||
import geopandas as gpd
|
||||
from sqlalchemy import create_engine
|
||||
|
||||
df = pd.read_parquet('/tmp/grid_data.parquet')
|
||||
gdf = gpd.GeoDataFrame(
|
||||
df,
|
||||
geometry=gpd.points_from_xy(df['center_lon'], df['center_lat']),
|
||||
crs='EPSG:4326'
|
||||
)
|
||||
|
||||
engine = create_engine('postgresql://wuhan_user:wuhan_password@localhost:5432/wuhan_disease')
|
||||
gdf.to_postgis('grids', engine, if_exists='replace', index=False)
|
||||
EOF
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 开发环境部署
|
||||
|
||||
### 1. 后端开发环境
|
||||
|
||||
```bash
|
||||
cd backend
|
||||
python3 -m venv venv
|
||||
source venv/bin/activate
|
||||
pip install -r requirements.txt
|
||||
uvicorn main:app --reload --host 0.0.0.0 --port 8000
|
||||
```
|
||||
|
||||
### 2. 前端开发环境
|
||||
|
||||
```bash
|
||||
cd frontend
|
||||
npm install
|
||||
npm run dev
|
||||
```
|
||||
|
||||
### 3. 运行测试
|
||||
|
||||
```bash
|
||||
# 后端测试
|
||||
cd backend
|
||||
pytest
|
||||
|
||||
# 前端测试
|
||||
cd frontend
|
||||
npm test
|
||||
|
||||
# E2E 测试
|
||||
cd frontend
|
||||
npx playwright test
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 生产环境部署
|
||||
|
||||
### 1. 安全配置
|
||||
|
||||
```bash
|
||||
# .env 文件
|
||||
POSTGRES_PASSWORD=<强密码>
|
||||
DATABASE_URL=postgresql://wuhan_user:<强密码>@postgres:5432/wuhan_disease
|
||||
|
||||
# 启用 HTTPS (通过反向代理)
|
||||
# 配置 Nginx SSL 证书
|
||||
```
|
||||
|
||||
### 2. 性能优化
|
||||
|
||||
```bash
|
||||
# 增加 PostgreSQL 连接池
|
||||
# 编辑 postgresql.conf
|
||||
max_connections = 200
|
||||
shared_buffers = 2GB
|
||||
|
||||
# 启用后端缓存
|
||||
# 编辑 backend/app/performance.py
|
||||
FEATURE_CACHE_TTL=7200 # 2 小时
|
||||
```
|
||||
|
||||
### 3. 日志管理
|
||||
|
||||
```bash
|
||||
# 查看实时日志
|
||||
docker compose logs -f backend
|
||||
docker compose logs -f frontend
|
||||
docker compose logs -f postgres
|
||||
|
||||
# 导出日志
|
||||
docker compose logs > all-logs.txt

||||
|
||||
## 故障排查
|
||||
|
||||
### 常见问题
|
||||
|
||||
#### 1. 后端无法连接数据库
|
||||
|
||||
```bash
|
||||
# 检查数据库服务
|
||||
docker compose ps postgres
|
||||
|
||||
# 查看数据库日志
|
||||
docker compose logs postgres
|
||||
|
||||
# 测试连接
|
||||
docker compose exec backend python -c "import asyncpg; asyncio.run(asyncpg.connect('postgresql://...'))"
|
||||
```
|
||||
|
||||
#### 2. 前端无法连接后端

||||
docker compose exec frontend curl http://backend:8000/health
|
||||
```
|
||||
|
||||
#### 3. 内存不足
|
||||
|
||||
```bash
|
||||
# 限制容器内存
|
||||
# 编辑 docker-compose.yml
|
||||
services:
|
||||
backend:
|
||||
deploy:
|
||||
resources:
|
||||
limits:
|
||||
memory: 2G

||||
**解决方案**:
|
||||
1. 缩小地图范围
|
||||
2. 使用区县筛选功能
|
||||
3. 等待数据缓存完成
|
||||
|
||||
### Q2: 时间轴播放卡顿
|
||||
|
||||
**原因**: 浏览器性能限制
|
||||
|
||||
**解决方案**:
|
||||
1. 降低播放速度
|
||||
