P. Proposal relates to computing and hydraulic technology: Mr.

It is known to count the number of sea gravitational waves, which contains a series half-adder, one of which is connected to the delay line, and the other is connected to the input bus. This device becomes more complex with the increase in the number of waves, and also needs a binary to decimal converter.

The proposed device is characterized in that o contains a correction circuit on two series-connected triggers, one of which is connected to the output of the sum of a half-adder sum, a transfer output connected to the trigger input and a delay line input connected to the second input of the second trigger This allows the registration result to be obtained in decimal code and simplify the device.

The proposed device uses a magnetostriction delay line. As a result of the magnetostrictive effect, electrical signals are converted into ultrasound and back after transmitting them through the acoustic conductor with a definite time delay.

The magnetostrictive delay line includes a Former 8, the outputs of which are connected to the coil of the transmitting transducer U located in the field of the constant magnet 10; duct P for transmitting ultrasonic vibrations; silencers 12, which prevent reflection of vibrations from the end of the duct; the coil of the receiving transducer 13 and the amplifier output signal 14.

and sequential binary half-adder is assembled on logical circuits "And 15-1b," I. / | And 1 and 20j inverters "NOT 21-22 and trigger 23.

The correction circuit is composed of two triggers 24 and 26, two circuits “And 26, 2 / and three circuits“ OR 28-30.

But tires 31-34 receive synchronized, impulses (SI).

In the gravitational sea wave counting unit, the sequential principle of information processing is applied, according to which the codes are processed sequentially in time, starting with the least significant bits. For the convenience of displaying information on the display and digital printing, a binary-decimal code is used in which every four binary digits (tetrads) are coded with one digit of a decimal number.

In the system of calculating the number of gravitational sea waves, the dynamic principle X | wound information is applied. The complete cycle of recycling TI information is determined by formula (1).

During one cycle, the information from the delay line I and the input circuit 5 (Fig. 1) is processed. The information converter is a serial binary half-adder 2 and a two-trigger correction circuit; pax 3 and 4. The conversion occurs sequentially in time, starting with the lower order bits.

To prepare the device, it is necessary to set it to its original state. To do this, for one cycle of TI, a bus signal is applied to bus 34 (FIG. 2). This signal closes the AND 27 circuit and thus breaks the information recirculation circuit. All codes "1 resulting from the previous operation of the device are erased. Then, via circuit 32, a signal is sent to the “Initial state, which, through the“ OR 28 ”circuit, gives the resolution to the“ AND 25 ”circuit. The clock signal CHi, which is active during the most significant fourth bit of all tetrads, passes through the“ AND 2B and four ”schemes. OR 2i, 30 writes to the delay line the initial binary code IT. IT. IT. IT. IT. IT. IT. ITO, (4) corresponding to the de facto number of OOOOOOOO. The initial binary code (4J recirculates the circuit; the output of the delay line 1 (Fig. 1) - the first input of the serial binary lolusummator 2 - the output 6 of the sum signal -

tshtery c), 4 - input of the delay line 1.

As soon as the signal about the effect of the sea wave arrives at the input of the device through the circuit, it opens the circuit “AND 18 (Fig. 2, and the clock signal CHi on the bus 31

gets to the second input of the binary half adder 2 (fig. 1) at the moment of arrival from the delay line 1 low-order initial code (4). The binary half-adder performs addition, and the resulting code is written through triggers 3 h 4 into delay line 1.

The result of the registration is recycled to

circuits: delay line 1 - half adder 2 -

triggers; (and 4 without change until 1

input 5 will not receive the next signal.

In this case, the binary half-adder .2 performs the addition and outputs the correct result to the delay line 1. This continues until the arrival on the 5th decade of the order of the input signal. When it happens

in the four lower-order bits of the code outputted by the half-adder 2 via circuit 6, the code "0000" is generated, and along circuit 7 a transfer signal is output to the next tetrad, i.e., to the next four binary bits. Signal

the transfer to the second tetrad, passing along chain 7 of the circuit “OR 28 (FIG. 2), issues a permit for the circuit“ AND 26, to the second input of which via the bus 33 at this time receives the signal CHj. The signal from the output of the circuit "And 26 writes

through the schemes "OR 29, 30 code" 1 at the place of the third and second bits of the first tetrad. Consequently, instead of the code "0000, the code" IT is written to the delay line in the first tetrad. In addition, the transfer signal from the output of the AND circuit 17 is delayed by the processing time of a single binary bit in the trigger 23. This ensures that the transfer signal through the OR 19 circuit is received at the upstream input of the binary half-adder 2 at the moment of arrival from the delay / low line second tetrad. The conversion of information by binary half-adder 2 during the passage of the bits of the second tetrad is carried out in the same way as the processing

bits of the first tetrad.

The device works in a similar way when a transfer signal appears from the second tetrad to the third and so on. In this way, the correction circuit is activated only at those moments when the transfer occurs on chain 7 of the fourth most significant bit of one tetrad to the first lower order next. In order to receive transfer signals from one tetrad to another after every ten impacts of sea waves, it is necessary to start counting in each tetrad not from zero, but from the code “IT. The code “IT in the process of work happens automatically, with help, correction schemes.

The advantage of the proposed device for counting the number of gravitational ATOR waves is the invariance of the equipment. So, for example, in order to get an astronomically large maximum possible number of registrations, it is necessary, according to formula (1), to either be doubled (the TI delay is doubled, which for the magnetostrictive delay line is achieved by extending the zvukoprovod, or at the same delay, twice clock signals khz. Pre-met invention
