Abstract

The invention provides a display panel control method, device, system, display board and equipment unit which relates to the field of air conditioning. The method comprises: saving parameters during normal operation of an application program in the display panel; obtaining an abnormal exit restart frequency of an application program under the condition that an application program restarts; write the parameter to the application with the application exception exit restart times greater than zero. The display panel is able to maintain a pre-restart operation state after the abnormal exit of thepanel application is restarted. In addition, by using the restart application program of the operating system, the display panel application program is not required to be manually restarted by the user, and the user experience is improved.

Description

technical field [0001] The present disclosure relates to the field of air conditioning, and in particular to a display panel control method, device, system, display panel and equipment unit. Background technique [0002] For a touch screen with a file system, when an exception occurs in the application. For example, if the data exceeds the bounds, the infinite loop cannot be jumped out, etc., the application program will send an error signal, the underlying system will automatically close the application program, and the user will see a black screen on the touch screen. Since the application program has been exited, the main board of the unit detects that the communication with the display is abnormal, and it will shut down in an emergency, requiring the user to manually restart the touch screen, and the non-memory parameters will be lost. Contents of the invention [0003] A technical problem to be solved in the present disclosure is to provide a display board control me...
