Abstract

The existing single-chip microcomputer control system and control system have the disadvantage of high failure rate. Modbus protocol is recommended based on the use of PLC (programmable controller) and camera DCS (distributed control system). The implementation indicates that the established DCS system is stable, reliable and has low failure rate. Therefore, the communication between the online PLC and the advanced computer can be carried out. It also has the functions of remote flow monitoring, remote intelligent meter reading, remote switch control, etc.
