The device works as follows.

The recorded information in the form of a Ν-bit binary code is read by the reader 17 from the magnetic media. Each read code is accompanied by a pulse of the first control output of the block 17 readout. Information on magnetic media is represented in the form of a multi-channel frame, where the recorded frame consists of sequentially recorded digital codes of analog information from individual information sources, and the last recorded code is a service code. A depth code corresponding to the moment of writing the marker signal is recorded in it sequentially, over several frames. · The overhead code is accompanied by pulses from the first and second control outputs of the magnetic information reading unit 17.

I

In the mode of registration of incoming information, digital codes corresponding to analog recording are received in the first 1 register by synchronizing pulses from the first output of reading block 17. The digital code from the first 1 register is decrypted by the decoder 8, and the pulse C. of one of its outputs is fed to the imaging unit 23. In addition, the pulses of the first control output of the readout unit 17 are counted by the first 5 counters and decoded by the second 9 decoder. Therefore, the signal will be only on the order of magnitude

the decoder 9, in the moment ”of which the unit 17 reads the corresponding ordinal code 'from a frame in which there is information about the registered analog signal. The switch 13 is made multichannel, and the control inputs through the switching elements 14 are brought into the zero potential bus.

If the key is open, the signal from the corresponding input passes. to the appropriate output, otherwise not. The pulses from the outputs of the switch 13 are combined to the element OR 15 and fed to the control input of the driver 23. If all the switching elements 14 are open, then each synchronizing pulse of the first output of the reading block 17 by means of the mentioned transformations goes to the control input of the driver 23, which adds up the write pulses to block 16 of the record / In the latter, the information is recorded on the electrochemical carrier 33 by permanently transporting it with a tape-moving mechanism 32. After switching 14 is closed, the corresponding ordinal pulse does not pass to its output, and consequently, the recording pulse by shaper 23 will not be generated. Thus, to eliminate redundancy by closing or opening the keys of switching elements 14, you can select information channels that need to be registered.

To digitize the information received, a pulse from the last output of the second 9 decoder arrives at a delay element 27, at the three outputs of which three detainees are formed relative to each other — ^ 5 pulses. According to the first pulse from the first output it .s information reading unit 17 corresponding to the last code of a frame is received in the second register 2 and immediately deshifri- ⁵⁰ ruetsya third decoder 10. When a code corresponding to the marker appears, the signal appears at the last output of the third 10 decoder, which passes through the open third 21 elements AND to the setup input of the first 28 trigger.

On its back edge trigger 28

installed in one state, opening the second 26 block of keys. Before the next marker code is received, the memory block 24 5 is filled as follows. The first service code from the following, after the marker frame, which carries information about the value of the number in the first digit, is entered through the third 10 πει шиф O encoder to the third 3 register by impulse received from the third output of the second 26 key block to the sync input of the third 3 register. By the following service code,

15 which contains the digit number of the received digit, information only from one of the second outputs of the third 10 decoder enters the fourth 4 register, by synchronizing its 20 pulse from the first output of the second 26 key block. By the impulse from its second output, the first 25 block of keys opens, forming an impulse, under the influence of which 25 are recorded in memory block 24 in a separate cell. On the next pulse from the third, the output of the second 26 key block, the third 3 register is cleared. Similarly, all numbers and digits are written into the corresponding cells of memory block 24. After filling in the memory block 24, the next marker code is again converted into a pulse at the last output of the third 10 decoder. This pulse through the open second element And 20 sets the second trigger 29 in one state. This closes the third 21 and opens the first 19 elements I. At the same time. to the leading edge from the first output of the second 29 trigger the first 28 trigger is reset to zero. After opening the first 19 elements And the pulses from the recording block 16, generated every 0.6 to 0.7 mm of the movement of the electrochemical paper 33, arrive at the installation input of the third 30 trigger and at the installation input of the second 6 counter, the state of which is decrypted by the fourth 11 decoder . A positive signal will be on the corresponding number of the registered output line. The same impulse is set in the third 30 trigger state, which opens the fourth 22 element I.

With this, the impulses from the generator 31. Impulses are rather high often.1183998 6

You arrive at the third 7 counter. Its condition is decrypted by the fifth 12 decoder, the signals from the output of which interrogate memory block 24. The signals from the memory block 24 are fed to the second inputs of the character generator 18, the first inputs of which receive the number of the digit being recorded. The generator 18 generates at its five outputs the pulses required to write each digit in separate lines according to the signals at its first and second inputs. The output signals for the individual lines of each digit are determined by the graphical representation of this digit in FIG. 2. When the first line of writing all digits is recorded, the transfer pulse from the third 7 counter returns the third 30 flip-flop to its original state, preparing it for recording the second line, which is performed in the same way by the second pulse from block 16 of the record. When recording all lines, a similar pulse from the second 6 counter resets the second 29 flip-flop again to zero. This completes the recording of digital information and prepares the third 21 elements AND for receiving the next marker pulse. In addition, a cleansing, block £ 4 of memory.

The proposed device, in comparison with the known, allows reliably and accurately register in the digital logging stations code information about the depth of the recorded logging signals.

20 depth goes through a separate service channel and its recording does not cause distortion of useful information.
