AI Technical Summary

Technical Problem

In the prior art, the communication connection between the controller and the second device may be unstable, especially when the signal connection is interfered with, malfunctioned or interrupted, making it impossible to effectively transmit control commands and monitoring information.

Method used

A communication module is provided, including first and second communication interfaces and a processing unit. After detecting that the idle time exceeds a predefined pause time, the module controls the second communication interface to transmit command messages, thereby achieving bridging between different communication protocols and ensuring the reliability of information transmission.

Benefits of technology

When the signal connection is unstable, different communication protocols can be bridged to ensure the safe operation of the second device and the reliability of information transmission, thereby improving the stability and security of the system.

Abstract

The present disclosure relates to a communication module comprising a first communication interface, a second communication interface and a processing unit, wherein the first communication interface is configured to receive an instruction message according to a first communication protocol, wherein the instruction message represents a predefined reference instruction, wherein the communication module is configured to detect an uninterrupted idle time during which the communication module does not receive a message via the first communication interface, and wherein the processing unit is configured to control the second communication interface such that the second communication interface transmits a command message according to a second communication protocol in response to the idle time exceeding a predefined stall time, wherein the command message represents the reference instruction. The present disclosure further relates to a communication system comprising the communication module and a method for the communication module.
