Which is good LED display (02985453602), preferred Shaanxi Hi-Tech Optoelectronic Technology Co., Ltd. Our company supplies school dedicated LED display 2.1 LED screen protection measures in terms of screen guard designed display systems have been leveled waterproof, dustproof, anti-burning, anti-corrosion treatment, salt spray test, the test results show that even under maritime conditions, the screen can also be long-term normal use. The products meet national industry standards, complex salt spray test requirements. Three precautions: All boards in the production of electronic testing has been completed using a dedicated three anti-paint treatment, ten effective and apply flame retardant material, it has dust, moisture, corrosion, fire-retardant properties. Between the pixels and modules with insulating rubber ring pressure seal to prevent moisture penetration. In vitro decorative screen can be very good flame-retardant material made from high-quality aluminum plate corrosion, tight seam between filling high weathering plastic sheet. Decorative seams filled with foam to help strip between modules and high-quality weather rubber padding to prevent moisture penetration. Screen internal mounting smoke, temperature sense probe pin is connected to the PLC control system monitoring screen in the state. Under special circumstances PLC system can automatically cut off the power and screen body alarm signal. Measures 2.2 Electrical safety assurance measures taken to ensure the electrical safety performance of chamber configuration PLC controller. By a PLC control cabinet panel, several steps will display the boot opening hours, in order to curb the impact of current switching power supply startup. PLC received machine instruction generation system operation logic, and the logic state of the contacts and fault information back to the system. Network system to control and monitor the implementation of the power supply circuit. Protection measures, including distribution cabinet overcurrent, short circuit, overvoltage, undervoltage, temperature, smoke sensors, etc., and with fault indication, abnormal timely warning. Network equipment UPS power protection of power supply for at least ten minutes, so that when a power failure occurs, the sufficient time for the system operator perform the correct processing operation. 2.3 anti-electromagnetic interference assurance measures applied to all boards through electromagnetic shielding material to prevent electromagnetic interference signal to the control circuit. Our products in terms of performance electromagnetic protection authority has been recognized by most.
