Control system for pipeline crawling robot detection

The utility model provides a control system for pipeline crawling robot detection. The pipeline crawling robot comprises a robot body and a plurality of pulleys connected with the robot body. The control system comprises a proximity switch, a photoelectric sensor, a PLC and at least two induction pieces. The PLC is arranged on the machine body, and the proximity switch and the photoelectric sensorare electrically connected with the PLC. The photoelectric sensor is arranged at one end, facing the advancing direction, of the machine body; wherein the at least two sensing pieces are respectivelyarranged on the side surfaces of the pulley and are sequentially arranged around the central axis of the pulley, the proximity switch is arranged on the machine body, and the motion trails of the sensing pieces are intersected with the sensing range of the proximity switch. The control system can detect the walking speed, the walking distance and obstacles encountered in the crawling process of the pipeline crawling robot
