Elevator trouble and stranded people incident take place occasionally, and the passenger can cause the panic after being stranded in the elevator, often can not get timely rescue in addition, and some elevators have installed emergency power source at present, can start reserve power supply and supply with the elevator and let the elevator emergency operation to the door district and open the door and release stranded passenger when power failure takes place for the elevator.
The elevator emergency device is divided into a power supply mode, a control right mode for taking over an elevator motor and a brake release mode, wherein the power supply mode is that the elevator automatic rescue device provides an inverter power supply for the elevator after detecting the power failure of the elevator and outputs a relay to trigger the elevator to enter an emergency operation mode. One is a mode of taking over the control right of the elevator motor, which is also called as an overhaul operation mode, and needs an emergency device to drive the elevator motor, and an output variable frequency power supply controls the motor to slowly operate to reach a door opening area and drives a door opening machine to open the door to release trapped passengers. The emergency system and the electric circuit of the motor driving part of the elevator system are mixed together in the mode, so that potential safety hazards are easily brought to the elevator, the installation is very complicated, and the cost is high. The other mode is a brake release operation mode, and particularly, by opening a brake device of an elevator main machine, an elevator car automatically slides to a door area through gravity traction based on the unbalance of the car and a counterweight and drives a door opening machine to open a door. The emergency device in the power supply mode cannot perform emergency rescue when the elevator has other faults except the power failure, and the method for recognizing the elevator fault by taking over the emergency device in the elevator motor control right mode and the brake release mode and the accuracy for judging the fault are not ideal, so that the elevator safety hazard which needs to be solved at present is that how to enable the elevator emergency device to perform automatic emergency rescue in time when the elevator has other faults except the power failure.
