.K 15, Simultaneously from the converter 9, clock pulses are received at the input of the frequency divider 10, the frequencies of which are divided to the necessary to switch the second binary counter 11, decoders (D) 13 and 14, Control D 13 and 14 to switch K 4 digital K 15 and 16 registers 17 and 18, Counter 11 is organized to six, the output code of which is fed to the input of the D 13 and 14 series-connected. A series of commands defined by the D 14 circuit is organized at the output of the D 14. Six three-digit commands control the circuit inclinometer, 3 Il.

The output of the second binary counter 11 through the binary decoder 13 is connected to the input of the matrix diode decoder 14, the output bus of which is connected to the address inputs of the analog switch 4, digital. switches 15 and 16 and serial registers 17 and 18, and the output of the first binary counter 12 is connected to the information input of the first digital switch 15, the outputs of which are connected to the information inputs of the serial registers 17 and 18, and their outputs are connected to

 5 information inputs of the second digital switch 16, the output of which is connected to the cable 19.

The device works as follows

20 . Signals from 11P 1 - 3, proportional to the desired angular parameters, are fed to the inputs of analog switch 4, to a control input from the output of the matrix diode decoder 14, six control codes are received in series, through which analog switch 4 provides a serial transmission to the OUT of three input signals

clock pulses with GUI 9. At the same time, from the output of logical element 8 to the input of the first binary counter 12, bursts of clock pulses proportional to the input signals are received, the number of which is read by the first binary counter 12, and converted into a binary code, sent to the input of the first digital switch 15; Simultaneously from GUI 9, clock pulses arrive at the input of frequency 10, the frequencies of which are divided to the frequency required for switching the second binary counter 11, decoders 13 and 14, which control the switching The digital switch 4, digital switches 15 and 16, registers 17 and 18. Binary counter 11 is organized to six (FIG, 3A), the output code of which arrives at the input of a series-connected binary decoder 13 and matrix diode decoder 14. At the output the latter is organized by a series of commands (Fig. 3b), determined by the circuit of the diode decoder 14 (Fig. 2). Six three-bit commands (Fig. 3b) control the inclinometer circuit as follows.

The two lower bits (a, a, j) control the operation of switch 4, and the most significant (a) switches switches 15 and 16 and registers 17 and 18. At the same time, analog switch 4 switches on the first 000 and fourth 100 commands 1, on the second 001 and on the fifth 101 commands of the PP 2, on the third 010 and the sixth 110 commands — PP 3. At the command of the higher order, the a, O, i.e. Com- munication TgiTOp 16 to register 18, in turn, register 17 switches to receive information, and register 18 to issue information, and 1 (the last three commands) switch Ator 15 is connected to register 18, and switch 16 to register 17, register 17 switches to the information output state, and register 18 to receive information.

Thus, according to the first command 000, information PP 1 through commutator 4, detector 5, LPF 6, PNVI 7, logical element AND 8 ,, counters 14, switch 15 enters register 17. At the same time, from register 18 through switch 16 cable 19 on po614

the surface of the earth is transmitted from the previous measurement cycle. Information from PP 2 and 3 is transmitted in the same way on commands 001 and 010. On the following commands 100,101 and 110 information from PP I - 3 through switch 4, detector 5, low pass filter 6, PNV 7, logical gate 8, counter 14 and switch 15 are recorded information is transmitted to the surface of the earth through the switch 16, the cable 19 to the surface of the earth, etc. The circuit runs continuously.
