Each link of the system control has a hot backup function, including video sending and receiving equipment, signal transmission cables, etc. It can ensure that when an unexpected situation occurs in a certain link of the system, the system can automatically diagnose and switch to the backup equipment at a very fast speed, and the entire switching process will not affect the display effect on the scene. For example: to meet the needs of the stage scene, the transparent display screen needs to be moved and spliced at the live broadcast site. If the signal input line of a display screen in the middle of the large screen is loose due to negligence of the staff or other reasons, in the conventional control solution, from the loose box to the end of the signal cascade, all displays will have no signal. If a hot backup solution is added to the control system, the hot backup function is activated at the moment the signal line is loose, and the display screen can still work normally without any impact on the live broadcast site.

2. Material selection

The key materials that determine the working stability of the transparent LED screen are LED lights, driver ICs, power supplies, power signal connectors and excellent structural design. Our requirements for material selection are: internationally renowned brands, relevant tests that are higher than industry standards, and various protection function requirements. For example, the requirements for the selection of switching power supplies are: overheat protection, AC input must support wide voltage and surge resistance. DC output must have overvoltage and overcurrent protection. The structural design ensures that the cabinet is beautiful and stylish while also ensuring good heat dissipation and fast splicing. 3. Transparent LED screen working status monitoring Computer real-time monitoring, including temperature, humidity, voltage, smoke, working status of cooling fans, etc. It can automatically adjust and handle various conditions that occur, and provide locations and alarms for abnormalities. For example: when the temperature inside a cabinet is relatively high due to the environment or other factors, the power supply inside the cabinet will be overheated at any time if it is not handled in time. If the working status of the display screen is monitored in this case, the system will reduce its internal temperature by intelligently adjusting the working status of the transparent display screen. When the intelligent adjustment cannot reduce the temperature to the set target, the system will alarm through the staff setting method, provide the location of the abnormal cabinet, and notify the staff to handle it in time. Ensure the normal working state of the display screen.
