(54) DEVICE FOR AUTOMATIC MEASUREMENT OF PARAMETERS OF MARINE FLOWS 34

on the direction sensor of the current vane, the house of operation of the reset unit 26 zero, voavra20, mounted on the case 21 of the sensor trigger 24 to the position 0.

the speed and direction of the flow of the circle surround- At each reset, the zero is sent

radius of their rotation. Each para pulse in the unit count

magnetically sensitive elements combining 5 counts 27. Next (at the time of complete, there is one magnetically sensitive element g filling the counter of single counts27) on the speed sensor 18 and one on the sensor to the rotation angle values 25, in the direction of the flow direction 2 O. Each one which by this time the pair has been connected to the inputs of block 22, in I (2O48 11) pulses, where tl is the number of each of which includes an element of delay-LO | pulses, proportional to the sum of all the ki - the waiting multivibrator 23 and the instantaneous flow rates included; the trigger 24 connected in series with it; a pulse generator is connected to the output of each of the blocks 22 is connected, 28, and to the output of the Tr rGa-breaker with the input of the previous block 22 and with the account of the Batel of the signal ZO of the radio transmitter 29. tick of the values of the angles of rotation 25, executed - “triggered at the moment of switching with triple binary trigger cells 31. Thus, until full, the recalculation coefficient m 2O48. Angle Angle Counter 25

; The triggers 24 are connected to the reset unit. The PDA is triggered p times and in ja 26, connected to the count “number”, there are consecutive matching samples 27, which execute “: the number of which is proportional to the environment in the form of binary trigger cells;

The signal converter 3O is connected to a trigger. Average instantaneous direction of flow.

25.j PROPOSITION AND 3 ABOUT AND |

The device works as follows. Device for automatic measurement When the device is lowered into the investigated 30 ° and parameters of sea currents, the medium (all triggers 24 are located in the flowing sensors of the speed and direction of flow O) is magnet 17, mounted on the ice, transducer, reset unit uyiia, jerked decelerated Savonius 18 rotor connected to the converter and the source (or on the vane 20) affects the number of single samples, one of the pairs (for example, pair 5) magnetically connected to the impulse generator of the sensitive elements and closes it. eni connected to a value counter

When pair 5 is locked, a pulse of rotation angles is sent connected to input 5 of block 22. The resultant signal is a radio transmitter signal, and the trigger of this block goes into a running order. what. for the purpose of raising the 1st, a pulse is sent, and a counter "of the reliability of automatic measurements of the angles of rotation 25 and at the entrance 4 of the average characteristics of the currents, as well as

block 22. At the same time, the trigger 24 of the block 22 determines their instantaneous values in qi (b

through the delay time of the waiting multivib view, the speed sensor is made in the virator 23 also changes to the position of the braked Savonius rotor, and

 and sends a pulse to the counter of values 45 of the transducer - in the form of magnetically sensitive angles of rotation 25 and to the input 3 of the block 22. of the elements included in pairs

This process continues until each other, and between the blocks, each pulse is not sent a pulse to the input one and a delay element of the signal and

block 22. As a result of this, in the counter trigger, .configured sequentially between

the values of the angles of rotation 25 will be sent so &. at the same time, the input of each of these blocks of pulses, proportional to instant-0, is connected with the corresponding value of the flow rate to the corresponding pair. The inter-sensitive elements, and the output shaft between single readings is instantaneous: the period is determined as the input of the previous block of transformed flow rates.
