Abstract

The invention discloses a remote automatic control system, and the system comprises a PLC control device, industrial control middleware, an Internet of Things industrial gateway and an Internet of Things cloud platform. The PLC control device is connected with the industrial control middleware, and the industrial control middleware is in communication connection with the Internet of Things cloud platform through the Internet of Things industrial gateway; the industrial control middleware comprises a data read-write module which sends a data read request / data write request to the PLC control device so as to carry out data read-write operation on a PLC register of the PLC control device; a first format conversion module converts the format of the output data of the PLC control device into aformat required by a Modbus protocol; and a second format conversion module converts the format of the output data of the Internet of Things cloud platform forwarded by the Internet of Things industrial gateway into a format required by the MQTT protocol. According to the invention, through the adding of the industrial Internet of Things gateway and the development of the middleware software, thePLC and Internet of Things communication is broken through, and the remote control system has the advantages of being high in industrial control function, good in man-machine interaction, stable, easyto maintain and capable of being perfectly fused with Internet of Things 4G communication.

Description

technical field

[0001] The invention relates to the technical field of industrial control, in particular to a remote automatic control system and an integrated remote automatic control system for rural domestic sewage. Background technique

[0002] At present, the integrated control system of rural domestic sewage is mainly divided into on-site control part and remote monitoring part. The on-site monitoring part adopts the traditional industrial control component PLC, which has the advantages of high stability, powerful functions in terms of control functions, and can be equipped with a man-machine interface with good performance. The operation experience is good and it is suitable for electrical maintenance personnel to maintain. Due to the closed bus technology used by PLC, it is difficult to perfectly integrate with the rapid iteration of today's IT technology, so the on-site monitoring part is limited to stand-alone operation or simple networking functions. The remote m...
