Problems solved by technology
However, at present, if a fault occurs during the use of the large-screen splicing display system, it cannot automatically detect the fault itself, and usually needs to be detected by manual methods or by visually observing whether there is a display fault
Not only is it time-consuming and labor-intensive, but also causes the failure to be discovered in the first time, which affects the use effect of the large-screen display system
[0003] In the prior art, the large-screen splicing display system is composed of multiple display cabinets, each display cabinet includes at least one display module, and the display screen is composed of the display modules, and the fault detection of the display modules in the display screen is performed. At this time, it can only detect whether the display box where the faulty display module is located is faulty, and the faulty display module cannot be detected through the existing technology, which is not convenient for maintenance personnel to quickly find the faulty display module, which has a certain impact on the maintenance process

This application relates to a display module fault troubleshooting method. The console sends a fault detection command to the control card, so that the control card detects the fault of the display module by detecting the change in the electrical signal of the display module, and reports the fault of the display module. The information is uploaded to the console, and the control card finds the location of the specific display module sending the fault according to the troubleshooting instruction sent by the console. The above method detects the fault of the display module through the mutual communication between the console and the control card, can find the fault in time, and troubleshoots and locates the fault display module through the troubleshooting command, which is convenient for maintenance personnel to quickly locate the fault display module and Repair the fault display module. The method can quickly detect and locate the faulty display module and its specific location, greatly improving the efficiency of maintenance personnel in overhauling the faulty display module, and reducing the manpower and material resources consumed in the display screen maintenance process.
Description
technical field [0001] The present application relates to the field of LED display, in particular, to a method and device for troubleshooting a display module. Background technique [0002] With the continuous development of science and technology, the application of large-screen splicing display systems in daily life has also increased, and most of them are installed on outdoor high-rise buildings as billboards. However, at present, if a fault occurs during the use of the large-screen splicing display system, it cannot automatically detect the fault by itself, and usually needs to be detected manually or by visual inspection to see if there is a display fault. It is not only time-consuming and labor-intensive, but also causes failures not to be discovered in the first time, affecting the use effect of the large-screen display system. [0003] In the prior art, the large-screen splicing display system is composed of multiple display cabinets, each display cabinet includes a...
