The moving circle of rotary encoder revolution, send an impulse singla to PLC, owing to be wound with the multilayer hawser on the reel, reel whenever rotates a circle, the cable length of receiving/releasing is different, and the girth of the Zhou Changda of outer hawser, nexine hawser is little, and PLC can only get an aviation value, estimate the rotate a circle cable length of receiving/releasing of current reel, and the total length of accumulative total hawser receiving/releasing is to obtain the submarine site of load.Simultaneously, also be that the cable length of receiving/releasing there are differences, even reel rotates with a certain constant rotational speed because reel whenever rotates a circle, the receiving/releasing speed of nexine hawser and outer hawser also is inconsistent, therefore load under water can not with on the steady state value/descending.

Traditional hydrographic winch receiving/releasing cable control system accurately sensing lead submarine site, lack effective monitoring to the load lowering velocity, along with the degree of depth of load dive is deepened, for example, there is a kind of research vehicle to need the hydrologic equipment dive to arrive 6000 meters even darker local work under water at present, difference between computing value and the hydrologic equipment actual position can become very big at this moment, the data that hydrologic equipment is passed back can not reflect truth strictly according to the facts, lowering velocity can't be monitored simultaneously, also has certain potential safety hazard.

Simultaneously, because PLC is as the control core, the current signal of its control loop is far smaller than the working current semaphore of electromagnetic valve and apportioning valve in the hydraulic efficiency pressure system, therefore can only be by behind control intermediate relay and the proportional amplifier amplifying signal, drive electromagnetic valve and apportioning valve in the hydraulic efficiency pressure system again, when electrohydraulic control system is comparatively complicated, often need to control more valve group, intermediate loop is that intermediate relay and proportional amplifier are just many like this, the control path of electrohydraulic system is very complicated, and the reliability of system reduces.
