Description

Telemetric systems are known that use conversion at the transmitting point of information signals to binary code.

The proposed telemetering system differs from the known ones in order to simplify the equipment at the receiving points and to ensure the possibility of maintaining reception on the standard digital printing apparatus, cells are installed at the transmitting point for storing the binary code and a device for converting the binary code into the decimal one.

The functional diagram of the described telemetering system is shown in the drawing.

At the initial moment of the system, the devices of the system are in the following states. Encoder / prepared to convert binary output signals from sensors. The recording device 2, which is a valve, is in the first position and prepares the first cell of the storage device 3 for writing. The reader 4 is in the first position and prepares the first memory cell for reading. The decimal register 5, to which, by a signal from the reading device, the contents of the corresponding memory cell is being overwritten, is in the zero state. The decimal binary counter 6 and the three-digit decimal counter 7 are also in the zero state. In this case, a ten-bit comparison circuit 8 outputs a comparison signal to differentiating circuit 9, but since this signal is a constant level, there is no signal at the output of circuit 9.

The six-position ring distributor 10 is at position "6, and the four-position valve // at position" 1. Triggers 12 and 13 are in state "1, and trigger 14 is in state" O. Pulsed generators 15 and 16 give the corresponding pulse series. When the start signal (input a) arrives, the encoder 1 performs information encoding, completing

No. 141679- 2 each coding cycle by issuing a signal "recording resolution to the recording device 2 and to the delay circuit 17. According to this signal, the information from the device coding is rewritten using the recording device. To the corresponding cell of the storage device i, after which the recording device switches to the next position, preparing the next storage device for recording. At the same time, the recording resolution signal passed through the valve / o n, delayed by the delay circuit 17, arrives at the encoder as a resolution signal of the next encoding cycle. The recording device in the last position, corresponding to filling the memory space of the memory device, switches to the first position, sends a signal to the trigger 14 via the differentiating circuit 19. The trigger 14, switches to the state "1, locks the valve 18 and stops coding." At the same time, the key 20 and the pulse series of the generator 15 are opened, the passage through the open counting valve 21 fills the binary counter 6 and the decimal counter 7. The results of the binary and decimal recalculation on the counters will be numerically equivalent, i.e. the result of the counter 7 will be is the decimal equivalent of the binary code of counter 6.

The reader 4 at each position issues the code of the corresponding cells of the memory device to register 5. Therefore, before the moment of recalculation of the pulse generator generator 15, the first cell code (respectively, the first position of the reader 4) was selected by counters 6 and 7 on register 5 and when recalculated, comparison circuit 8 will compare the result of the counting in the counter 6 with the binary code of the first number fixed in register 5, issuing a pulse to the trigger 12 of the counting when comparing via the differentiating circuit 9. The latter, switching to the "O" state, closes the counting valve 21 and thereby turns off the generator 15. Simultaneously, the trigger 12 opens the valve 22 and the pulse series of the generator 16 passes to the ring distributor 10 (through the open valve 23 and the key 24, which controls the ring distributor //. The last one in the first position prepares the input bus "gap (0) of the combinatorial grid 25 generating telegraph codes. In the second position (c), the distributor // opens ten clauses 26 of the output of hundreds of ten counters 7, while Nathorn grid 25 is given a value of hundreds of discharge counter 7. In the third position the valves 27 are opened bits tens counter 7.

In the fourth - valves of 28 bits of units. Thus, codes "space and values of bits of hundreds, tens and units of the number recorded on the counter 7" are alternately transmitted to the transmitting devices through the valve 29.

At the end of the transmission cycle (when the distributor is switched from the fourth to the first position), an impulse is issued, bringing counters 6 and 7 and register 5 to the zero state. In this case, the trigger 13 (metering) is transferred to the "O" state and locks the key 24. The reader 4, when received on its input of this reset pulse delayed by the delay circuit 30, switches and issues the next memory cell code to the register 5. With the same delayed reset pulse, the one-shot 31 is excited and sends to the collecting circuit 32 "OR the pulse, with the falling edge of which trigger 12 is transferred to the state" 1, and the delayed (delay circuit 33) falling edge of the pulse to the state "1 trigger 13. Delay in the switching of the trigger 13 to the state "1" eliminates the possibility of the pulse 16 of the generator 16 slipping through the valve 22 and the key 24 at this moment.

When the trigger 12 is set to the state "1, the valve 21 opens and the generator / 5 pulse series fills counters 6 and 7. The process
