FIG. 1 1P | edited The structure of the device for information about telemetry information; Fig. 2 and 3 are time diagrams of the device operation in the mode of outputting information for registration.

The telemetric information processing device comprises a readout unit 1, a linear unit 2, a buffer rearHipTip 3, a starch decoder 4, an encoder 5, an ul-indicator 6, a first memory block 7, a ban 8 block, nopiBbm 9 and a second 10 matching blocks. the first repistr 11 of the record, t | rigger 12 of launching the microchromic node 13, which includes wait generator 14, register 15, progr-amm field 16, first read register 17, block 18 constant coefficients, third bloch 19 matching, computing control unit 20, computing unit 21, nomaid generation unit 22 , the fourth matching unit 23, the second recording register 24, the second memory block 25, the address register 26, the one-shot 27, the waiting gene | p, ator 28, the second register 29 of the reader, the second decoder 30, the recording block 31, and the first. element, the element OR-NOT 32, the element AND 33 and the form factor of 34 clock pulses.

The device works as follows.

Information from a punched tape through block 1 is read, or directly through it (block 2 enters buffer register 3 | And is stored at the first level of triggers (| not shown in the drawing)) of this rep. When the reader reads | implant ultrasound, information is overwritten from ne (the trigger stages of the buffer penKCTipa 3 to the second step, and from the outputs of the second step TipHirreipoB para1raf. The code goes to the first decoder 4. After

of this, all triggers of the buffer register are reset to their initial state. The pulses of control of the buffer register 3 ("Write," Read, "Reset) are formed in read block 1 or line block 2. In decoder 4, the code is converted to decimal code. From the outputs of the decoder 4, the digital information signals are assigned to the corresponding inputs of the cipher | Shtor 5. The digits, except for “O,” go directly to the inputs of the encoder 5, and the digit “O after analysis” to the encoder 5 through the null indicator 6.

The encoder 5 provides the P | Reconversion of the decimal positional code from the output of the decoder 4 to the four-digit D1VOICH1NO-D60YAT11 code “8-4-2-1, and the null indicator 6-blocking the recording in the first block 7 steps; zeros from the buffer | reg register 3. The device is intended for processing numbers of fixed length. If the number is smaller than the set number, then zero is written in the absence of bits. 25 For example, the number 39 with a fixed length of four bits is recorded as "0039. Zero-I (ND | Ikator 6, in this case, is known to pass the digit O to the encoder 5.

3.0 Digit O enters encoder 5 only after recording any other digit. So in the number 0039, two zeros are excluded and the number 39 is sent to the encoder 5. The processed Il1Nformation contains the address code .35 of the object from which the measurement information came. There is a need to output address information directly to print without recording 8 block 7 of memory 7. Therefore, with 31 information | 40 ne | p |, the initial signal comes from neipBoro defyhratora 4 to block 8 zapra | matching units, which prohibits the passage of address information 5i into memory unit 7.

After reading the address information taking into account the address width, the prohibition block 8 changes the polarity of the signal to blocks 9 and 10, which ensures resolution 0 of the measuring information (Mats to memory block 7). Writing information to the memory block is synchronized by pulses from the first register 11 records, to the input of which synchronization pulses are received from block 1 of reading.

After the end of the recording of information, the impulse from repistra 11 is fed to the reading unit 1 and stops it. The next, last, pulse is from register 11 to 0: steps into the input of the trigling | 12 run of program node 13. Trigger 12 starts the standby generator 14, and | m pulses (t 0.3 s) enter register input 15. Position pulses with the output of the repistor 15 fall on the software field 16, with

the output of which control commands agree on typing nporpaiMMe to the co-ordinate nodes of the device. One of the im- pulses, corresponding to the command “input of a number,” starts the first register 17, counting, which sews to read the information from block 18 of permanently different coefficients and the first block of memory. The information from blocks 7 and 18 goes to the third block 19 and then goes through the control block 20 to calculating block 21. The block 19 matches, also receives the signals of the commands themselves and the signs of the commands from block 22 form, on the signal from The field is 16. The calculated block 21. performs calculations using a predetermined algorithm.

After the end of the computation, the information and the information accompanying the information from the computing unit 21 are transferred to the fourth matching unit 23. From the popram field, an impulse passes to matching unit 23, which starts the second register 24 of the record, and the results of the calculations are overwritten from the calculating unit 21 through the matching unit 23 to the second 25 memory. In block 25, the address information is preliminarily recorded from block 9 of matching with the aid of register 26 of the register address for which the clock pulses are received from block 1 of reading in the presence of an enabling signal from block 8 of the prohibition.

One-shot 27 with a delay time (m 0.5 s) is triggered oddly with the supply of a permissive signal for recording information into memory 25. A delayed impulse triggers a waiting 28. A series of pulses from the waiting generator 28 fills the second read register 29, which is read by information from the memory block 25. The first pulse of read register 29 is fed to block 25, and reading is made: Information from one of the bits in the memory cell of block 25. The second pulse simultaneously goes to memory block 25 and the input of the OR-PE element 32. This reads information (“O or“ 1) from one of the SINGLE-NIGHT Triggers of the Memory Block.

At the same time, at the output of the OR-NOT 32 element, the signal "O" appears, which is fed to one of the inputs of MCIHTA AND 33. At the same time, it is present at the zero output of the second control. 30, the signal “1 through the element AND 33 does not arrive at the input of the block 31 of the refining and indication.

Thereby, the registration of information (digits "O) by block 31 in the absence of information" 1. On the requested trigger of memory block 25 "is prohibited. The friction of the pulse; the penHCTipa 29 readout pulse is fed directly to the 25 byte block; information from the next bit of memory cells is compiled. The fourth pulse is simultaneously sent to the memory block 25 and the input element OR-NOT 32. Information is read from another trigger, and so on.

The information (except for the digit "O) from the memory block 25, in the form of the parallel code" 8-4-2-1, goes to the decoder 30, is decrypted and passes to the block 31 of the registration and display. If, when reading information from the memory block 25, it was polled once, the memory cells recorded information “O”, then nothing came from the output of block 25 to the decoder 30, and the digit “O is formed directly by the decoder 30 and using the elements OR-NOT 32, and 33. In this case, when a clock pulse arrives from the high end of the water: the gate 34 to the decoder 30 at its zero output appears the signal "1, which is fed to one of the inputs of the element And 33; Another input passes the signal "1 from the output of the OR-NOT 32 element. The signal" 1, which appeared at the output of the AND 33 element, is directly fed to the recording and display unit 31 and is registered as the digit "O.

In the general case, the output of the .and; information to the registration by the block 31 is made only when the clock pulses come from the waiting generator 28 through the shaper 34 of the clock pulses to the decoder 30.

The time diagrams of the device operation in the mode of outputting information for registration are presented in FIG. 2. Here is the time, and 28, 29, 25, 34, 32, 30 and 33 are the outputs of the corresponding elements according to FIG. 1 For example, the case is considered when the number 10, 101 is recorded in memory block 25 (here “1 is the code of digits from 1 to 9, and“ O is the lack of information in the polled memory block of block 25). As can be seen from FIG. 2, the duration of the clock im: the pulses at the output of the imaging unit 34 are less than the duration of the clock pulses of the waiting generator 28. The front and rear edges of the clock pulses of the imaging instrument 34 are shifted by time t relative to the input pulses. This makes it possible to eliminate the effect of the delay of siphnals on the logical elements (when turned on; or disconnecting them), for, depending on how they are physically implemented, and on the way of incorporating them into the scheme.

FIG. 3 shows the time diagrams of the device operation in the mode of outputting information to the register: this is when the waiting pulses of the direct generator 28 are used as clock pulses. In this case, due to the effect of delaying ohms on the logical elements of the device, 1 false pulses are received M: Scarlet for the input of the block 31 of the registation and indication and a record is made of additional numbers or distortion of them.

According to the introduction of false impulses is of a casual nature, however, this reduces the reliability and reliability of the processing results. After the end and repistition, unit 31 generates an optual that triggers unit 1. The entire cycle of reading, converting, processing, and reproducing the information is generated and burned.

In the standby mode of the device, when the information is received directly from the channel, the nature of the information processing is not mixed. Only the storage of the processing of information (the storage unit provides a block of 2). The frequency of arrival of information should not be higher than the frequency of processing.

And the use of new elements and devices is advantageously distinguished by the proposed device for processing telemetric information from the specified prototype, so KaiK excludes the possibility of generating false simuli (noise) that can distort the information when it is processed and registered. This increases the reliability and reliability of the processing results.
