PIPELINE ROBOT, PIPELINE VIDEO-SIGNAL ACQUISITION AND TRANSMISSION DEVICE AND PIPELINE DETECTION SYSTEM AND METHOD

摘要

A pipeline robot, a pipeline video-signal acquisition and transmission device, and a system and method for use in pipeline detection; the pipeline robot comprises: a camera module (1) and a crawler (3); the camera module (1) comprises a front-view digital camera, a first microprocessor and a rotary motor; the crawler comprises a frame (31), wheels (32) on both sides of the frame, a drive motor, a group of sensors, a second microprocessor, a network transmission module, and a first power carrier module; a cable tray comprises a power line, a second power carrier module, a fourth microprocessor and a network communication module; an acquisition control terminal is a mobile terminal equipped with a detection module. Synchronized transmission of power supply, video signals and control signals on a same line may be achieved by means of only two-core wires, thus reducing the number of cables needed, reducing weight, and achieving long-distance transmission by means of said method; moreover, remote operation may be achieved by means of merely installing a detection module software on the mobile terminal without needing a conventional large-scale detection case.
