For outdoor LED displays, because they are used outdoors. Therefore, it must be treated differently from ordinary indoor LED displays. Outdoor LED display installation requirements are also different from ordinary indoor LEDs. The installation must be done in detail. Otherwise it is very likely to cause trouble. Six ideas for outdoor LED display installation 1. Install lightning protection devices on the display and buildings. The main body of the display screen and the shell are well grounded, and the ground resistance is less than 3 ohms, so that the large current caused by lightning can be discharged in time; the display screen may be attacked by strong electricity and strong magnetism caused by lightning. 2. The waterproof measures of the LED display screen itself. The joint between the screen body and the building must be strictly waterproof and leak-proof; the screen body must have good drainage measures, once accumulated water occurs, it can be discharged smoothly; pay attention to waterproof and moisture-proof. The display screen is installed outdoors, often exposed to the sun and rain, wind and dust cover, and the working environment is harsh. Electronic equipment getting wet or severely damp can cause short circuit or even fire, cause failure or even fire, and cause loss; 3. Select industrial-grade integrated circuit chips with operating temperature between -40°C and 80°C to prevent overheating in winter Low prevents the display from starting. 4. Install ventilation equipment to cool down so that the internal temperature of the screen is between -10℃~40℃. An axial fan is installed on the top of the back of the screen to dissipate heat; the display itself will generate a certain amount of heat when it is working. If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit may not work properly or even be burned, making the display system unable to function properly. Work; 5. Ultra-high-brightness light-emitting diodes must be used. In order to ensure long-distance visibility under strong ambient light, ultra-high-brightness light-emitting diodes must be selected; increase contrast. Wide audience coverage, long viewing distance requirements, and wide field of view requirements; environment The light changes greatly, especially if it is exposed to direct sunlight. 6. The display medium adopts a new wide viewing angle tube with wide viewing angle, pure color, consistent and coordinated, and a life span of more than 100,000 hours. The outer package of the display medium is currently the most popular rectangular tube with a cover, silicone seal, and no metalization assembly; The model is exquisite and beautiful, sturdy and durable, and has the characteristics of anti-sunlight, dust-proof, waterproof, high-temperature resistance, and anti-circuit short circuit. The installation precautions of outdoor LED electronic display screens involve the future use and safety of the product, and must be treated strictly and seriously. How to debug the led display 01. What are the possible reasons for the failure to load? The loading failure may be caused by the following reasons, please compare with your operation according to the listed items: A. Ensure that the control system hardware has been correctly powered on. (+5V) B. Check and confirm that it is used for connection control The serial cable of the monitor is a straight-through cable, not a crossover cable. C. Check and confirm that the serial cable is intact and there is no loose or falling off at both ends. D. Check the LED display control software and the control card you choose to choose the correct one. The product model, the correct transmission method, the correct serial port number, the correct baud rate and the correct setting of the address bit and baud rate on the control system hardware according to the DIP switch diagram provided in the software. E. Check the jumper cap Whether the jumper cap is loose or off; if the jumper cap is not loose, please make sure that the direction of the jumper cap is correct. F. If the load still fails after the above inspection and correction, please use a multimeter to measure whether the connected computer or control The serial port of the system hardware is damaged. To confirm whether it should be returned to the computer manufacturer or the control system hardware for testing. 02. What may be the cause of the communication failure? The reasons for the communication failure and the loading failure are roughly the same. It may be caused by the following reasons. Please compare with your operation according to the listed items: A. Make sure that the control system hardware is correctly powered on. (+5V) B. Check and confirm that the serial port cable used to connect to the controller is a straight-through line, not a crossover cable. C. Check and confirm that the serial port cable is intact and there is no looseness or fall off at both ends. D. Compare with the LED display control software Choose the correct product model, correct transmission method, correct serial port number, and correct baud rate with the control card you choose, and correctly set the address bits and waves on the control system hardware according to the DIP switch diagram provided in the software. E. Check whether the jumper cap is loose or falling off; if the jumper cap is not loose, please make sure that the direction of the jumper cap is correct. F. If the load still fails after the above inspection and correction, please use a multimeter to measure Check whether the serial port of the connected computer or control system hardware is damaged. To confirm whether it should be returned to the computer manufacturer or the control system hardware for testing.
