Description

The invention relates to industrial fishing, in particular to control systems for fishing gear in depth.

According to the main author. St. No. 644432, a control system for a fishing gear, such as a trawl, at a depth, comprising a vessel-waiter trawl complex, a trawl winch drive, trawl depth sensors and fish schools, contours for controlling the depth of the trawl by changing the speed of the vessel and by changing the length of the warriors, overload measurement units is known trawl winch and main power plant, power sensor of the main ship plant [lj.

The known system is characterized by insufficient efficiency due to the presence of spikes.

The purpose of the invention is to increase the efficiency of fish production by eliminating spans.

This goal is achieved by the fact that the control system of the fishing gear is additionally equipped with a preliminary assessment unit for the possibility of transferring the trawl to the horizon of the school of fish, the inputs of which are connected to the outputs of the sensors for the depth of the school of fish, the working length of the etched warriors and the depth of the trawl, and two switching devices, when this, the first input of the first switching device is connected to the output of the unit for determining the estimated length of the warriors, the second input of the first switching device and the first input of the second switching device VA connected to the output of the preliminary assessment of the possibility of transferring the trawl to the horizon of the school of fish, the second input of the second switching device is connected to the output of the summing unit, and the outputs of the switching devices are connected respectively to the second and third inputs of the logical switch.

The drawing shows a functional diagram of the proposed system.

The fishing gear control system contains a complex 1 vessel-trawl vessel, a logical switch 2, a fish school depth sensor (hp), a main power unit 4 of a vessel, a vessel speed controller 5, a summing unit 6, a trawl depth sensor (hr) 7, a drive 8 winch trawls, 9 waverb length regulator, trawl winch overload unit 1G, unit ί 1 for determining the estimated length of the yoke, force gauge 12 (T) in the yards, sensor 13 of the working length of the etched warriors (U), unit 14 for measuring the overload of the main power plant sensor 15 power (P) of the main power installation, block 16 preliminary assessment of the possibility of transferring the trawl to the horizon of the school of fish, the first 17 and second 18 switching devices.

Block 16 has three inputs connected to sensors 3, 13 and 7 of the depth of the school of fish, the working length of the etched warriors and the depth of the trawl ^5, respectively, and one output. The first input of the switching device 17 is connected to the output of the unit ί 1 determining the estimated length of the cords, and the second and first inputs of the switching device 10 18 to the output of the preliminary evaluation unit 16, the possibility of transferring the trawl to the school of fish. The second input of the switching device 18 is connected to the output of the summing unit 6. Outputs commuting ₁₅ ing devices 17 and 18 are connected respectively to the second and third inputs of the logic switch 2.

The system operates as follows.

Simultaneously with the input of the ios value of the depth of the school of fish hp to the fishing gear control system, the initial values of the working length of the etched warriors L »are introduced!! ·; trawl depth h _y to block 16 of the preliminary assessment La on the horizon school of fish. last cart _{2 <;} acts on switching devices 17 and 18, allows the operation of the entire fishing gear control system only if the grandfather has a greater distance from the trance to the school of fish than the calculated path that the trawl passes and translates it to a depth of 3δ of the fish school.

At the same time, block 16 is a counting-resolving device that performs the function of calculating the horizontal projection of the distance 3 between the trawl and the school of fish by the input of the trawl (tra-S bobbing length of the etched aerov ^t - ₃ and the depth of the trawl by; and ..... - fish: - (distance to the jamb and elevation angle) to determine the horizontal projection of the rh.slgt: south of the path Sp, with the lroyde-inogral of the thai and its height 40 to the depth of the jamb? Of fish, by solving a system of differential and logical equations describing dthozics. > m: t. usrayalenich instrument loas minutes, and comparing the horizontal tatohe prookgschy calculated ;, about ⁴⁵ Tsuchi distance from beds I to L the fish school with allocation difference signal - & S - S .....

In the case, the electronic signal of the difference DZ is positive, the block 16 gives out a signal that is torn out once more than the device 17 and B.

In such a sawn-off shotgun?., Pr - '. I am settling. Yessgema Upranlesin is a more effective instrument of communication with that. that breaks are excluded.
