The key materials to determine the working stability of the display are LED lights, drive ICS, power supplies, power supply signal connectors and excellent structural design. Our material selection requirements are: International well-known brands, in order to exceed the requirements of industry standards related testing, as well as the requirements of various protection functions. For example, switching power supply selection requirements: There is overheating protection, AC input to support the wide voltage, surge resistance. DC output to have over voltage, over-current protection. Structural design in the guarantee box beautiful fashion at the same time, but also to ensure a good heat dissipation mode and fast splicing method.
Every aspect of the system control scheme has the function of hot backup, including video sending, receiving equipment, signal transmission cable, and so on, it can ensure that in a part of the system in the event of an unexpected condition, the system can automatically diagnose and switch to the standby equipment at a very fast speed, the entire switching process will not affect the display effect. For example: In order to meet the needs of stage scenes, the display needs to be in the live scene to move mosaic modeling. If due to staff negligence or other reasons, a large screen in the middle of a display signal input line has been loose, in the conventional control scheme, from the loose box start, to the end of the signal cascade, all the display will have no signal. If a hot backup scheme is added to the control system, the hot backup function starts at the moment when the signal line is loose, the display screen can still work normally and will not bring any effect to the live scene.
LED Full-color display working status can be used in real-time computer monitoring, including temperature, humidity, voltage, smoke, cooling fan working status and so on. Can be automatically adjusted to the occurrence of various conditions, the exception to provide location and alarm. For example: When a box because of environmental or other factors caused by the internal temperature of the box is relatively high, then in the case of no timely treatment, the internal power supply at any time will occur over-temperature protection. If the display is monitored in this case, the system will reduce the internal temperature of the display by intelligently adjusting the working state of the display. When the intelligent adjustment can not reduce the temperature to set the target, the system will be through the staff set the alarm, and provide abnormal box location, notify staff timely processing. Ensure the display is in normal working condition.
