第三阶段：核心业务服务实现完成

Browse Source 
实现的核心服务：
- PingService: 设备Ping检测 (System.Net.NetworkInformation.Ping)
- DataParserService: 发那科JSON解析 (tags数组/字段映射/数值处理)
- DeviceCollectionService: 设备采集服务 (Ping检测+HTTP采集+重试)
- ProductionCalculator: 产量差分计算 (同一程序/程序切换/跨天处理/异常值保护)
- DataStorageService: 数据存储服务

其他服务保持桩实现：
- AuthService, UserService, PermissionService
- LoggingService, AlarmService, TemplateService 等
