The invention relates to a PLC-based cable laying ship hoisting and dragging control method. The PLC-based cable laying ship hoisting and dragging control method comprises the following steps of setting control parameters and controlling a towing winch and a storage winch according to a constant tension mode, a dragging mode and a butt joint mode, wherein the constant tension mode includes controlling the towing winch and the storage winch to enable the tension of cables between the storage winch and the towing winch as well as between a pulley device and a cable burying machine; the dragging mode includes controlling the towing winch and maintaining the tension of the cables between the pulley device and the cable burying machine within a threshold range; the butt joint mode includes controlling the storage winch and the towing winch, and during a cable collecting process, maintaining the tension of the cables between the pulley device and the cable burying machine within the threshold range. The PLC-based cable laying ship hoisting and dragging control method achieves automatic control over the major control functions of a system, thereby saving repeated manual adjustment of the system; when entering a working mode, the system can automatically achieve intended targets according to set requirements.
