Description

one

The invention relates to industrial fishing, in particular, to the speci fi ed devices for controlling the operation of the trawl. A device for measuring the trawl fishing force, containing a depth sensor, an analog-to-pulse code converter, a tape recorder, a decoder, and a decoder is known.

However, the known device is characterized by insufficient efficiency and the meters measured by it indirectly characterize the degree of shredding of the fishing trawl.

A device for measuring technical power is known, which contains sensors of speed, horizontal and vertical opening, connecting to the corresponding ;; polish receiver C /. one.

However, such a device does not provide the necessary accuracy due to the asynchronous operation of the receiver-recorders, the consequence of which is the necessity of comparing the peach parameters recorded in the receiver-recorders of this device. In this case, an error in the trawling process accumulates, which leads to an unreliable control.

The purpose of the invention is to improve the accuracy of measuring the opening degree of a fishing trawl.

The goal is achieved by the fact that the device containing speed sensors, horizontal and vertical expansion, connected to corresponding receiver recorders, is equipped with a timer, a synchronization unit connected in series by an electronic switchboard, an input unit, a secondary information processing unit, and a digital indlator and three similar chains with successively connected analog-to-digital converters 3anoMHHaioiipiMH epementa - and electronic keys, the outputs of the latter are connected to the input elec throne switch, the second output information input unit connected to the clock synchronization unit, and starting the inputs of the last second inputs of memory elements connected to the timer, which is connected to the input horizontal priemoregistrator disclosure, and the outputs of the latter and priem2361

A horizontal opening sensor 1, the output of which is connected to transceivers, is used to measure the horizontal opening of a trawl registered with the B receiver 4. Speed sensor 2, the WHITE INPUT which is connected to the transceiver 5, is used to measure the speed of the trawl recorded at the transceiver 5.

Analogue-1f o F F o r o sconce 3 about a 8-10, in the moves of which are connected to the outputs of the corresponding transceivers 4-6, and the outputs - to The information inputs of the storage elements 12-14 are entered to convert the primary parameters from analog to binary form.Synchronization unit 11, one input (starting) of which is connected to the output of timer 7, and the other (synchronous input) to the clock output of input information block 19 serves to synchronize on the input and control of the electronic key from 15-17. The storage elements 12-14, the information inputs of which are connected to the outputs of the analog -; - And (| Transducers 8-10, control inputs to timer output 7, and outputs connected to the inputs of electronic switches 15-17, are used to record and store the current values of the primary parameters. The electronic keys 15-17, the control inputs of which are connected to the outputs of the synchronization unit t1, the information inputs to the outputs of the storage elements 12-14, and the outputs to the input of the electronic switch 18, are intended for reading information from the storage elements 12-14, the electronic switch 18, the input which is connected to the outputs of electronic keys, and the output. - to the input unit 19, for transmitting information from electronic keys 15-17 to the input unit 19. The secondary processing unit 20 connected to the output of the unit 19, as well as the digital indicator 21 connected to the output of the secondary information processing unit 20, are used to register measurements technical capacity. The device works as follows. In the process of trawling, information from sensor 1 of horizontal opening of sensor 2 of speed, sensor 3 of vertical opening opens to the inputs of corresponding receiver recorders 4-6 and is recorded in them. Timer 7, which sets the device polling cycle, is triggered by pulses coming from the output of the receiver. 4, horizontal disclosure, at the same time, the primary parameters in analog form are input to the corresponding analog-to-digital converters 8-10. The transformed information is fed to the inputs of the memorized elements 12-14 and is recorded in them for the duration of the 1-pulse write, arriving at the 11 inputs of the control of the storage elements 12-14 from the output of the timer 7. At the same time, the same recording pulse goes to the start input of the synchronization unit 11, whereby the inhibit and enable pulses for the control inputs of the electronic switches 15-17 are activated. From the output of the public electronic keys 15-17, information is transmitted by the electronic keyboard rytapy 18c to the input unit 19. In this case, the input unit 19 inputs information into the secondary processing unit 20 and, after the input of the lower digit of the binary code, generates an input end clock input to the synchronous input of the synchronization unit 11, in which the rescale and inhibit pulses are generated for the following electronic keys 15-17 . In block 11, the synchronization is carried out by counting the clock pulses received from the input block 19, and after that. three pulses, corresponding to the number of polled 4-6 receivers polled, the synchronization unit 11 returns to its original state. When the next write pulse is received from the output of timer 7 to the start input of the synchronization unit, the device operation cycle repeats. During the period of the impulse, all receivers are surveyed. The current value of the technical engine is calculated in the secondary processing unit 20 and is recorded on the digital indicator 21. The introduction of the proposed device makes it possible to increase the accuracy of measuring the technical power of the trawl by 30-35%, which in 1 year only in one of the regions represents a saving of about 161.5 thousand rubles.
