The invention discloses a communication method between a control module and a display module, and belongs to a communication failure removal method. The communication method comprises a control module, a display module and a displayer, wherein the control module is connected with the display module through a communication interface; the display module is connected with the displayer; the control module comprises a monitoring component; the monitoring component monitors times of interruption at the communication interface; the preset value of times of interruption in a unit time is prestored in the control module; the monitoring component compares the times of interruption in the unit time at the communication interface with the preset value of times of interruption; the abnormal situation is judged if the times of interruption at the communication interface is smaller than the preset value of the times of interruption; and then the control module restarts self or the communication interface or the display module to eliminate the abnormal situation. According to the technical scheme, the communication method and the industrial control display device have the benefits that the detection to the reliability of communication connection between the control module and the display module is ensured; and the communication abnormity can be automatically recovered to the largest extent.
Description
technical field [0001] The invention relates to a communication troubleshooting method, in particular to a communication method between a control module and a display module and an industrial control display device. Background technique [0002] The driving part of the industrial control display device is generally a display module, which communicates and integrates with the original system through a serial port or other communication methods to realize the expansion of the display function of the original system. However, when the display module communicates with the control module of the original system, in some industrial environments where the environment is relatively harsh, the communication between the two is susceptible to interference, or the quality of the display module itself is unstable, resulting in blurred screens, black screens, and data on the terminal display device. Phenomena such as not updating. Contents of the invention [0003] In view of the above-...
