Revision core: first, tightened emission limit, electromagnetic radiation limit of elevator control cabinet, frequency converter, wireless module reduced from 40dBμV/m to 30dBμV/m, conducted interference reduced by 30%, avoiding interference with building security and communication systems; second, immunity upgrade, passing 4 tests: electrostatic discharge, radio frequency electromagnetic field, electrical fast transient, surge, stable operation under ±25% voltage fluctuation, strong electromagnetic environment, anti-interference level upgraded to level 3; third, smart system special, adding EMC requirements for IoT module, 5G communication, AI controller, wireless signal shielding attenuation ≥60dB, preventing data transmission interference and packet loss; fourth, unified test method, global unified test environment, equipment, process, judgment standard, eliminating international trade technical barriers; fifth, safety redundancy, automatically switch to safe mode when EMC fails, brake and door system operate independently, ensuring safety. After implementation, elevator electromagnetic interference faults decreased by 70%, global adaptability of smart elevators improved.
