摘　　要：设计了一种基于Modbus协议的电气开关柜智能监测系统。该装置由探测器、现场监控器、嵌入式监控主机组成。现场监控器能实时采集配电箱里面的电流、电压、温度、漏电流、浪涌保护的失效状态等信息,并作出预警、报警、输出脱扣动作;同时基于Modbus协议,经RS-485总线将数据传输回到嵌入式监控主机上进行储存、查询、输出打印等处理。An intelligent monitoring system used in electrical cabinet was designed based on modbus protocol.The device consisted of detector,on-line monitor,embedded monitoring host.The on-line monitor can acquire current,voltage,temperature,leakage current,surge protection failure status information of the distribution box in real-time,and then make early warning,alarm,output tripping action.And based on modbus protocol of RS-485 data bus,it can communicate with the embedded monitoring host which can be responsible for the job of store,query and print.
