Emergency Power Evacuation Engineering

The ARD (Automatic Rescue Device) is a critical safety system engineered to prevent passengers from being trapped inside an elevator during a building power failure. Technically, the ARD is an intelligent battery-backed inverter system that monitors the incoming three-phase power. Upon detecting a power loss, the ARD engages within seconds, utilizing its stored energy to release the motor brake and move the cabin to the nearest floor at a reduced speed. It determines the "light-load direction" (either up or down) by analyzing the current required to move the motor, ensuring the rescue is performed with minimum energy consumption. Once the cabin reaches the landing, the ARD provides power to the door operator to open the doors and release the passengers before safely shutting down.
