摘要
设计一套基于PLC控制的数据监控系统,采用西门子S7-200 SMART PLC并通过Modbus RTU通信实时读取多台智能电力仪表的各种参数,再使用西门子触摸屏对参数进行汇总、监控及查询。该系统配备报警功能,可在运行设备电压过高或电流过高的情况下及时通知用户,用户根据通知能够及时做出处理,防止发生安全生产事故。
This paper designs a set of data monitoring system based on PLC control,the system adopts Siemens S7-200 SMART PLC and reads various parameters of multiple intelligent power meters in time through Modbus RTU communication,and then collects,monitors and queries the parameters using Siemens touch screen.The system is equipped with alarm function,which can timely notify users in case of excessive voltage and current of the operating equipment,users can deal with it in time,so as to prevent the occurrence of safety production accidents.
