The invention discloses a semi-physical simulation test platform for a trawl fishing boat dragging winch. It includes host machine, target machine, data acquisition card, rotary encoder, torque sensor, hydraulic winch, hydraulic motor, safety valve, check valve, servo proportional valve, cable, hydraulic source and oil tank. The host computer establishes the discrete mathematical model of the trawl net and net gear and the mathematical model of the hydraulic system controller, compiles it into C code and downloads it to the memory of the target computer. After solving the calculation, information such as the tension of the trawl net and the net position are obtained, and the target machine realizes the simulation of the trawl resistance of the trawl net by controlling the cable tension of the hydraulic winch. The present invention realizes the simulation of the trawl resistance and the net position during the trawling operation process through the semi-physical simulation of the trawler towing system. Experimentation opens the way.
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...
