Research on Electromagnetic Compatibility of LED Display of Mine Safety Monitoring System

Based on the introduction of the constitution and working principle of LED in mine monitoring system display screen, based on switching power supply, the panel itself, from the oscillator, signals line layout analysis of three aspects of the monitoring system of LED display by electromagnetic interference, combined with the specific test case, separately from the suppression of the radiated and transmitted to harass two to carry out rectification, finally through the signal line, power line and ground wire layout solve the antenna vertical polarization direction on radiation the unqualified.
