Multi-channel communication control system and channel control method

The embodiment of the invention discloses a multi-channel communication control system and a channel control method. The system comprises a communication controller, a PC, a field device group based on the MODBUS protocol and a control center. By adopting a multi-channel RS485 interface, different types of field devices based on the MODBUS protocol can be accessed to different networks such as the Ethernet, WIFI and 5G. If one conversion interface network is abnormal or fails, other conversion interface networks can be immediately switched to be accessed, so that the communication reliability of the control system is improved, an efficient enterprise industrial internet system can be established for an enterprise, original equipment does not need to be eliminated too early, the utilization rate of the equipment is increased, the investment and operation cost of enterprises are reduced, and the application level of the industrial Internet of the enterprises can be promoted. 本发明实施例公开了一种多通道通信控制系统及通道控制方法。系统包括通信控制
