The invention discloses an LED module fault detection method, and relates to the technical field of LED module fault detection, and the method comprises the following steps: 1, an LED control card is connected with an LED module through a flat cable, and the outlet flat cable of the LED module is connected with an LED fault detection card; 2, the LED control card is connected with the LED fault detection card through an independent serial port line for transmitting verification data, and the verification data is compared with module outlet data; and 3, the LED fault detection card is connected with the GPRS network card through a serial port RS485, and a real-time state is submitted to the cloud server platform at fixed time intervals. According to the invention, automatic detection of LED dead pixel faults is realized, the inspection labor cost is reduced, the time from fault discovery to emergency repair is shortened, the complaint rate is reduced, temporary emergency repair is changed into planned maintenance, and the image and public praise of municipal road administration public facilities are improved.
Description
technical field [0001] The invention relates to the technical field of LED module fault detection, in particular to a method for LED module fault detection. Background technique [0002] The LED module self-inspection system includes process functions such as detection of each point of the traffic signal LED screen, self-inspection of bad point failures, reporting to the cloud platform, viewing on the browser or mobile phone, push notification alarms, etc. However, the existing detection methods require It costs a lot, and it takes a long time from fault discovery to emergency repair, which greatly reduces the efficiency. For this reason, it needs to be improved. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a method for LED module fault detection, which solves the problems mentioned in the background art. [0004] In order to achieve the above purpose, the present invention is achieved through the following...
