In the newly presented model, the application layer uses modbus protocol, the transmission layer uses TCP and the Media Access Control protocol uses IEEE802.3 standard. The monitoring computer collects measuring data by polling method.

• 在该模型中，应用层协议采用Modbus协议，传输层协议采用TCP协议，介质访问控制协议采用IEEE802.；3标准，上位机通过轮询的方式对测量数据进行采集。
