The invention provides a universal method for detecting accidental movement of an elevator car. The method comprises the following steps that S1, the distance L1 between a leveling photoelectric sensor and door area photoelectric sensors, the distance L2 between the two door area photoelectric sensors and the value of a shading plate L3 in a shaft are measured before inspection; s2, a laser ranging device is fixed to the top of the elevator car through a fixing base; s3, inputting the initial measurement values L1, L2 and L3 at the management end, detecting the response time t1 of a laser ranging device, the distance A1 of the lift car leaving a landing when accidental movement is detected, the response time t2 in a system in a braking subsystem, the expected maximum speed Vmax before the lift car decelerates, and the allowable movement distance A2 corresponding to the test speed; s4, carrying out a car accidental movement protection device test method operation test on the elevator car; and S5, related data of the accidental movement process of the lift car is obtained and processed, and the accidental movement of the lift car is detected.
