Abstract

The invention discloses a PLC wireless communication fault detection system and method, and relates to the technical field of wireless communication. The PLC wireless communication fault detection system comprises a monitoring terminal and a PLC, wherein the PLC comprises a PLC control unit, two wireless communication modules and a state monitoring unit; the state monitoring unit is used for respectively monitoring state information of the two wireless communication modules and transmitting the state information to the PLC control unit; the PLC control unit is used for controlling switching toselect the wireless communication modules according to the state information of the two wireless communication modules; and the monitoring terminal comprises a communication analysis unit, a log recording unit and a storage unit. The two wireless communication modules are integrated on the PLC control unit, and the state information of the currently used wireless communication module is monitoredby means of the state monitoring unit; when the state information of the wireless communication is an abnormal state, the PLC control unit switches to use another wireless communication module to carry out wireless communication with the monitoring terminal; and thus the abnormal communication of the PLC caused by the abnormality of the wireless communication module is avoided, and the loss is reduced.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to a PLC controller wireless communication fault detection system and method. Background technique [0002] At present, with the vigorous development of the Internet of Things technology, the wired networking form of uploading equipment data and status parameters is being replaced by the wireless networking technology based on the Internet of Things technology. The wireless networking will provide scalability and convenience for the data center computer room monitoring system. It brings innovation, greatly reducing the construction difficulty and wiring cost of data center computer room monitoring. However, when the wireless communication module in the current industry fails, the connected equipment will also experience a corresponding communication interruption. The interruption and loss of data will cause the remote signaling, remote sensing, and telemetry functions...
