Design of Emergency Response Control System for Elevator Blackout

摘要

The emergency system will cooperate with an integrated controller with low-speed self-rescue function. When the elevator is powered off, the inverter power supply will supply power to the elevator controller. The controller will drive the traction machine to slowly stop the car to the nearest level position to open the door. During the normal operation of the elevator, the SCM should monitor the power supply situation at all times and control the system circuit to charge the battery. After the power failure of the elevator, the single chip should be able to respond in time, control the inverter power supply to supply power to the elevator controller and output emergency operation signals and phase sequence short circuit signals to the controller. After the emergency operation is finished, the single chip also needs to receive the stop signal output by the controller and then control the system to enter a standby state. The emergency system is one of the defense lines to ensure the safety of elevators. The elevators using the emergency system can effectively reduce the occurrence of trapped accidents and make the emergency rescue process more convenient.
