1. Inspection of the power supply system of the screen body: First, check whether the line connection in the distribution box is rusty or loose. For safety, the grounding of the electric box must be normal. Regularly check the power line to avoid line damage.
Reinforcement inspection of internal components and steel frame structure: When receiving the warning of natural disasters such as bad weather, it is necessary to check the stability and safety of the various components of the screen, especially the small parts of the steel structure. If there is a problem, Deal with it in time.
2. In addition, LED advertising screens are high-power-consuming equipment. After a long period of operation, due to multiple start-stops and operations, the wiring terminals of the power supply part will become loose due to cold and heat, and the contact will be weak, forming a virtual connection. It will heat up and even ignite the plastic components next to it. The signal wiring terminals will also become loose due to changes in the ambient temperature, and moisture corrosion will lead to poor contact, which will lead to equipment failure. Therefore, the LED advertising screen must be tightened regularly. When adjusting the fasteners, the force should be even and appropriate to ensure firmness and effectiveness.
3. Inspection of lightning protection facilities: Regular inspections of lightning rods and grounding lines. The facilities should be tested after thunderstorms, and if damaged, they must be replaced in time.
4. Inspection of the control system of the LED advertising screen: Regularly check the reliability of the system to ensure its normal operation; all lines and equipment of the large screen should also be checked regularly to avoid accidents.
