The trigger trigger 26 generates a start-stop signal device.

Comparison element 27 compares the group number from the polling unit 1 with the group number to which a particular subscriber belongs.

Element And 28 controls the reset of the request stored in readiness trigger 29.

One-vibrators 31, 32 generate signals indicating the subscriber’s readiness for exchange and belonging to the group being surveyed, respectively.

The buses 4-7, to which the control system is connected, load and start the device.

Subscriber units are connected to each analysis unit 3 via buses 15, 14, such as processors of a multiprocessor system, input-output devices, information-measuring system modules, and so on.

In the Operation process, subscribers, in accordance with the task algorithm, are grouped into groups that require synchronous group control. Group subscribers are labeled with a single group number. The number of possible groups p «Ј N (N - the number of subscribers). Groups are formed and broken up at random times. The one-vibration 31, 32 blocks 3 are connected in parallel to the buses 13, 12, respectively, that implement the logic function. INSTALLATION AND

The device works as follows.

Before the polling begins, the counting coefficient is loaded into the register 18 from the bus 4 by the signal from the bus 5.

The Start signal coming from input 7, the start trigger 26 scrolls 26 and the clock pulse from the generator 22 clock pulses passing through the AND 25 and OR 19 elements writes the zero code to the counter 20. The comparison element 21 compares the contents of the counter 20 with the counting factor coming from register 18, and, since there is no coincidence, connects the clock series to the counting input of the counter 20. A consecutive polling of groups of subscribers begins. The group number from the output of the counter 20 via the bus 11 is fed to the inputs of the comparison elements 27

in all blocks of 3 analysis. Comparison element 27 compares the group number code from bus 11 with the group number to which the subscriber belongs, arriving via bus 14. In those analysis blocks 3 where the codes (the subscriber does not belong to this group) did not occur, the output of the element 27 the comparison is zero, and at the output of one-shot 31, 32 - a single potential. In those blocks 3, where the group number codes have coincided, an analysis of the readiness of subscriber 1 for exchange is carried out. If the subscriber is ready, then the bus 15 is set to 1 readiness trigger 29. With the subscriber belonging to this group and its availability, a zero signal appears at the output of element II 30 and a one-shot 31 delivers a unit potential to bus 13, and a one-potential one switch 32 to a bus 12 - zero potential. If the subscriber belongs to the group being surveyed, but is not ready for exchange, the One-Vibrators 31, 32 give zero potential for buses 13, 12. Three situations are possible:

a) all subscribers belonging to the Group being surveyed are ready;

b) at least one subscriber belonging to the group being surveyed is not ready;

c) all subscribers do not belong to the group being surveyed.

If all subscribers belonging to the polled group are ready to exchange, then the group readiness signal is sent via bus 13 to block 2. On bus 12 to block 2, a zero signal is issued, indicating that this group is functioning on the field. Element AND 24 generates a single signal that resets the start trigger 26, stops the operation of the device, and informs the control system via bus 8 that the group whose number is on bus 11 is ready to be exchanged. The control system registers the number of the group ready for exchange, and a single signal at input 6 resets the requests to the subscribers belonging to this group, the same trigger signal triggers the start trigger 26, and the polling cycle continues.

If at least one subscriber belonging to the group being surveyed is not ready, then a single signal on the bus

13 is not issued and polling unit 1 proceeds to polling the next group.

If no subscriber belongs to the group being polled, then bus 13 is given a single potential, which is fed to the second input of element II 24. To the first input of element II 24, a single signal is received via bus 12, which blocks the output of the group readiness indication signal to bus 8 (into the control system). The device proceeds to poll the next group. When the group number from the counter 20 coincides with the group number recorded in the register 18, the comparison element 21 outputs a single signal to the second inputs of the AND elements 16, 17, closing the AND element 17 and opening the AND element 16. Another pulse from the generator 22 clock pulses through elements II 16, OR 19, writes a counter into zero code 20. After this, a new polling cycle begins.
