## 主要改进 - 实现 /api/status/model 接口，返回真实PDMS模型状态信息 - 使用MDB.CurrentMDB、Project.CurrentProject等AVEVA API获取真实数据 - 移除硬编码的CurrentSession、PositionInfo、PdmsSpecific等复杂结构 - 简化数据模型，只保留核心的真实数据字段 ## 技术实现 - 通过DbSession获取真实的用户名、会话开始时间和持续时间 - 通过WorldMembers()获取真实的模型元素统计 - 修复DateTime类型的null合并运算符编译错误 - 清理不使用的方法和类定义 ## API返回数据 现在返回的数据主要包含真实的PDMS信息： - ModelLoaded: MDB连接状态检查 - ProjectName: 真实的设计数据库名称 - MdsName: 真实的MDB名称 - UserName: 真实的数据库会话用户 - StartTime: 真实的会话创建时间 - TotalElements: 真实的模型元素数量统计 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
