Title:
SYSTEM AND METHOD FOR CONTROLLING RETRIEVAL OF CABLE
Document Type and Number:
WIPO Patent Application WO/2018/214679
Kind Code:
A1
Abstract:
Provided are a system and method for controlling retrieval of a cable. The control system comprises: an alternating current generation device (10) provided at a cable (30) and generating an alternating current by means of movement of the cable (30); a drawing motor M, wherein retrieval of the cable stops when the drawing motor M stops; and a motor switch module (20) connected to the alternating current generation device (10) and the drawing motor M, the motor switch module (20) controlling the drawing motor M to halt after generation of an alternating current. The control method comprises: generating an alternating current by means of movement of a cable being retrieved; and in response to generation of the alternating current, controlling a drawing motor to stop so as to stop retrieving the cable. The system and method realize automatic control on retrieval of a cable, thereby increasing control accuracy with respect to retrieval of a cable.
