Research on anti-interference of electromagnetic radiation of elevator’s door control system in anechoic chamber

The elevator experimental platform and simulated EMI signal system were built to test anti-interference of radiation in anechoic chamber. The destination was to find the frequency ranges and electric field intension which made the elevator lose its functions. The influence of shielding and ground connection would be researched as well. All the malfunctions would be summarized during the whole experiment. And the reasons of those malfunctions should be found. Some measures were taken to avoid the malfunctions under the electromagnetic interference signals. All the whole experiment provides new ways to keep the safe motion of the elevator equipment in public occasions.
