问题：
- 硬编码字段映射（gbName、name、app）
- 逻辑重复散落多处
- 格式写死无法配置
- 未基于数据库实际表结构
- 可扩展性差
重构方案：
1. 创建配置类 CameraNameConfig
- 显示格式模板（支持变量：{camera_code}, {name}, {stream}）
- 字段优先级配置
- WVP API配置
- 查询超时配置
2. 创建服务类 CameraNameService
- 查询摄像头信息（get_camera_info）
- 提取名称字段（extract_name）
- 格式化显示名称（format_display_name）
- 一站式方法（get_display_name）
3. 重构路由层
- 移除硬编码逻辑
- 使用camera_name_service统一处理
- 删除旧的_get_camera_info函数
- 简化代码结构
架构优势：
- 配置驱动：格式通过环境变量控制
- 单一职责：服务只负责名称处理
- 可扩展：新增格式无需改代码
- 可测试：服务独立易于测试
- 模块化：逻辑集中便于维护
配置示例：
```bash
WVP_API_BASE=http://localhost:18080
CAMERA_NAME_FORMAT={camera_code} {name}/{stream}
CAMERA_QUERY_TIMEOUT=5
```
修改文件：
+ app/config.py - 添加CameraNameConfig配置
+ app/services/camera_name_service.py - 新建服务
+ docs/camera_name_config.md - 配置文档
~ app/routers/yudao_aiot_alarm.py - 使用新服务
测试结果：
- 告警列表: cam_1f0e3dad9990 → cam_1f0e3dad9990 大堂吧台3/012 ✓
- 设备汇总: cam_c51ce410c124 → cam_c51ce410c124 大堂吧台1/008 ✓
