The device (Fig. O on the transmitting side contains groups 1 and 2 of the elements AND, element 3 AND, element 4 NOT, de encoder 5, generator 6 pulses, generators 7 single pulses, block 8 of issuing information, shift register 9 containing the bit 10 markers Bit 11 of the strobe signal, group of bits 12 of the tracking signal, group of information bits 13, bit 14 and 15 of the potential signal, device input 16 — gate signal input, tracking signal input 17, information input 18, input 19 the potential signal of the tracking. Transmitting and receiving The sides are connected by a communication channel 20. At the receiving side, the device contains an information receiving unit 21, a shift register 22 containing the same bits as the register 9 on the transmitting side, a control trigger 23, a counter 24, a decoder 25, groups 26 and 27 elements I. control trigger 28, pulse generator 29, device decoder 30, 31 — output potential tracking signal, information output 32, tracking output 33, gating output 34. Information block 8 (figure 2) consists of a decoder 35, elements 36 and 37 NOT, elements 38-40 And, counter 41. Block 21 receiving information (fig.Z) consists of elements 42, 43 And, element 44IL, the trigger 45. The device operates as follows. The Discharge Discharge (CP) signal is a strobe signal, is fed to input 16 and is removed from the output 34 of the device. The Beginning of Array (HM) and End of Array (KM) signals are tracking signals, are fed to input 17, and are removed from the output 33 of the device. The information is given to input 18 and removed from output 32 of the organization. In this case, the device input 19 is not used, and the generators 7, 7 should be blocked (by switching, communication, not shown) before starting work. When implementing the timing diagram (Fig. 4), the device operates as follows. The HM signal, by the CP signal, and the CP signal itself are recorded in bits 12 and 11 of register 9, respectively. With a nonzero state of register 9, a level 1 appears at the output of decoder 5, according to which generator / J generates a pulse, which sets bit 1 to 10 of the marker, writes the number of shifts code (corresponding to register bit 9) to counter 41 and starts the counter 41. When the content of the counter 41 is not equal to f About the decoder 35 blocks group I and element 3 And through element 36 does NOT unlock element 40 I. As a result, pulses from generator 6 through element 40 begin to flow into counter 41, to the input of register shift 9 and the inputs of elements 38 and 39, with in the outputs of which are transmitted to channel 20 of the communication of the contents of register 9 in a serial paraphase code. At 1, in discharge 10, register 9 impulses is output from element 38, and in discharge 10, from output 39, after the contents of counter 41 overflow (i.e., the contents of all the register 9) by null with the counter 41, decoder 35 locks element 40 (through element 36) and unlocks group 1. Thereafter, the information on input 18 in the presence of a CP signal is locked into bit 13 of register 9, and the CP signal into bit 11. Then the decoder 5 will work again and the contents of register 9 will be transmitted to channel 20. Similarly th channel manner in the register 9 is transferred to the contents after recording it in the CM signal. On the receiving side, in this case, the consecutive paraphase code z of channel 20 of communication with 1 in the bits corresponding to the signals of the CP and HM, and the discharge of the marker goes to the elements 42 and 43, while the pulses corresponding to 1 in the transmitted bit go to element 42, the potential 1 or O is removed from the unit byte of the trigger 45 in accordance with the content of the transmitted bit, and from the output of element 4A is the write-shift pulse.

The contents of register 9 are rewritten into register 22. After 1 bit of the marker is wits to bit 10 of register 22 (i.e. the contents of register 9 will be completely transferred to register 22) by level 1, the groups 26 are unlocked from the output of this bit. and 27 and installation in the coil: the trigger 23, which blocks the block 21, sets in the counter 24 a code corresponding to the required duration of the signals that are removed from the device outputs, and starts the counter 24. When the certain number of pulses from the generator 29 arrives at the counter 24 contain nd it becomes equal to the code I ... 10. This code would work decoder 30 and its output signal will set the state .in O register 22 resulting from the outputs 34 and 33 snimuts signals CP and TM. After the next pulse from the generator 29, the counter 24 will set the code III .., This will trigger the decoder 25 and the trigger 23 will be set to O, which will unlock the block 21. The next pulse will overflow the counter 24, as a result of which O. After that, the receiving side is ready to receive the contents of the register 9. In a similar way, the receiving side also works when receiving the contents of the JP 9. Reader 9. with the information and the CM signal.

Thus, the signals and information supplied to the device inputs on the transmitting side are transmitted in a sequential code to the receiving side, where signals and information are taken from the device outputs in the same sequence that is fed to the device inputs.

In order to transfer information from an external subscriber to the ACS, in accordance with the considered time diagram, one transmitting and one receiving semi-sets on the receiving side are required on the transmitting side. When an external subscriber operates with an automated control system, information is transmitted in a parallel form.

The Ready-to-GCH signal is transmitted from the external subscriber to the ACS and is a potential tracking signal, is fed to the input 19, and is removed from the output 31 of the device. Cig Willingness-2 (D) is similar

signal C

.. but transmitted from the ACS to the external subscriber. The Pickup Signal is Allowed (CP) and the information is similar to the corresponding ones in the time diagram considered. ; .

In order to transfer information between an external subscriber and an ACS, it is necessary to have two semi-sets in the external subscriber and the ACS (transmitting and receiving), and the transmitting semi-complement as part of the ACS and the receiving semi-complement as part of the external subscriber are intended to transmit the Gu signal.

In the absence of a signal P at the input of element 4, the low level, and at the output, a high level at which reHepatop 72 produces a signal, 1, which is set to state I, bit 5 of register 9, which causes the decoder 5 to trigger, and the contents Register 9 (with installed in the G-section.

5 row marker) is transmitted to register 22. Level I from the output of bit 10 of register 22 opens group 26, with the result that trigger 28 is set to state O (if it was in state I before) or confirmed its zero state. Output 31 will be level O (no signal 1).

When a signal P appears on the transmitting side, generator 79 will operate and set bit state 14 to register 9. After that, the contents of register 9 are transferred to receiver side register 22, where the signal from the output of bit 14 sets up a trigger through open group 26 28 to state 1. At the output (31 is level I. The trigger 28 is at state I until level O is not reached at input 19.

To transfer information from the subscriber to the ACS (Fig. 7), a one-half semi-complement is required as part of the subscriber and one receiving semi-complement as part of the ACS. The Start of Array (NM), Start of Word, (HC), End of Word (CS) and End of Array signal are required. (KM) are fed to input 17 (and recorded in the corresponding bits of the group of bits 12), and removed from output 33. The Pickup Enabled signal is fed to input 16, and the information is fed to input 18. Device input 19 is not used .

To transfer information from abo nent to the automated control system in accordance with the time diagram shown in fig. 6, in the subscriber and in the ACS, it is necessary to have two half sets (transmitting and “receiving) for transmitting the Request and Dunning signals from the ACS to the subscriber, and information from the subscriber to the ACS.

Since the Request, Pickup and Information signals are not gated, the inputs on the transmitting side are not used and they are given a constant level 1 to these inputs in order to unlock Group 2.

Signals Request and Signal removed produced at input I7 and removed from output 33 of the device, with each signal Request and Signal removed produced are recorded in the corresponding groups of bits 12.

Thus, the proposed device has a wider scope, since it allows the exchange of information from the ACS with external subscribers in different time diagrams of operation of subscribers (both for the considered time diagrams and similar ones).

In addition, the device makes it possible to significantly reduce the number of communication channels, as the tracking information for transmission over the communication channel is converted from parallel and serial. The transmission can be made both by a consecutive paraphasic code, and by a sequential single-phase code (one core each), with a corresponding change in the issuing and receiving units.
