MODBUS RTU通信协议在变压器气体在线监测系统中的应用

Application of MODBUS RTU Protocol in the Online Monitoring System for Gas Dissolved in the Transformer Oil

MODBUS协议是应用于电子控制器的一种通用协议,将MODBUS RTU串行通信协议应用于变压器气体在线监测系统。通过利用MODBUS RTU协议功能代码,实现了主机和现场检测仪表间的包括实时数据查询、历史数据查询、参数修改、时钟同步等功能。

MODBUS protocol is a kind of general protocol applied into electron controller. Applying MODBUS RTU protocol in the online monitoring system for gas dissolved in the transformer oil. It realized the real-time data query, historical data query, parameters modification and system clock synchronization between host and field instruments by using the function codes MODBUS RTU protocol.
