An in-line detection and automatic rescue method for elevator failure is able to isolate main power supply and start emergency power supply to power the drawing motor, electromagnetic band brake and the door motor to open the door when the elevator fails. It features a detection circuit which can examine at any time if the safety citcuit of elevator is in normal state and the failure signal collector can be used for in-line detection of elevator to determine if it is electrically powered and levelled with floor, or if the band brake is opened, or if it is in maintenance state. Its advantages are simplified failure detection, high safety and high automation level.
