The invention provides a detection system and a detection method of friction elevator rope groove wear loss, and belongs to the detection system and the detection method of the elevator rope groove wear loss. The system comprises an upper computer, a laser displacement sensor, a collector, a direct-current power source module and a sensor support. The laser displacement sensor is installed on the sensor support, and the output end of the laser displacement sensor is connected with the collector. An encoder is installed on a roller of an elevator, the output end of the encoder is connected with an Ethernet, and the output end of the collector is connected with the input end of the upper computer through an interface of the Ethernet. The upper computer achieves real-time analysis of the on-line detection of the friction elevator rope groove wear loss and determines the wear loss conditions of different positions according the encoder. The detection system and the detection method have the advantages that the real-time quick on-line detection of the wear loss of a friction liner can be achieved, the friction liner needing to be replaced can be positioned precisely in real time, the working intensity of workers is reduced, the service life of a steel wire rope is prolonged, and the problem that real-time monitoring of the wear loss of the friction line cannot be achieved in a project is solved.
