The invention discloses a semi-physical simulation test platform for a trawler warp winch, which comprises a host, a target machine, a data acquisition card, an angle-position encoder, a torque sensor, a hydraulic winch, a hydraulic motor, a safety valve, a one-way valve, a servo ratio valve, a cable, a hydraulic source and an oil tank, wherein the host establishes a discrete mathematical model of a trawl warp and a netting gear and a mathematical model of a hydraulic system controller, the models are compiled into C language codes, and then, the codes are downloaded into the memory of the target machine; the target machine resolves the winch torque and the angle displacement signal which are acquired by the data acquisition card to obtain the information of the tension of the trawl warp, the net position and the like; and the target machine realizes the simulation of the trawl resistance of the warp winch by controlling the rope tension of the hydraulic winch. The invention realizes the simulation of the trawl resistance and the net position in the trawling process by carrying out semi-physical simulation for a trawler towing system, can be used for experimental research of the hydraulic system and the controller of the warp winch, and creates a new way for the test of the trawler warp winch on land.
Description
technical field [0001] The invention relates to a fishing winch test device for an ocean-going trawler, in particular to a half-physical simulation test platform for a trawler winch. Background technique [0002] When large-scale ocean-going trawlers carry out trawling operations, the control of the trawl is very critical, and its control level directly affects the fishing effect. The control difficulty of the trawl net is greatly improved, and the heave of the wave will directly lead to the change of the tension of the trawl mesh opening and the trawl net. It leads to the deformation of the trawl gear. Therefore, improper control of the trawl wire winch will not only lead to a decrease in catch, but even cause the wire breakage and damage to fishing equipment in severe cases. It can be seen that the trawl wire winch must be adjusted according to the characteristics of the working conditions. And the operation requires real-time adjustment of the pulling and releasing speed...
