    /// 昂坤Viper-RTC测温数据交互流程简介
    /// 1：上位机连接昂坤软件启动的服务器，昂坤服务器启用  工控机的IP + 53888固定端口，上位机连接服务器获取温度数据
    /// 2：昂坤软件通过USB线连接主机盒子获取温度，上位机不用干预
    /// 3：昂坤通讯特性，上位机发送一条指令后，服务器会一直安装设定频率，一直发送数据，上位机只接受就可以了
    /// 4：上位机读取数据，通过昂坤提供的库，调用连接和数据获取方法
    /// 5：断联分为昂坤软件服务器、USB两种断联和重连判断，例如：昂坤软件未打开或UBS线松动
    /// 6：继承ITempData接口，上层使用接口获取数据，方便以后扩展测温硬件
