On the third side, from the third output of the first distributor 23, a signal is outputted once per p steps, which is fed to the input of the counter 18 and changes (increases) the counting result by one. The signal at each of the N first outputs of the counter 18, for example, the i-th, appears during and at the time of polling and receiving information about the status of all sensors of the i-th group of each of the transmitting sides. After receiving each N-ro control signal, t, e, once per nN cycles, the counter 18 from the second output supplies a signal to the input of the second distributor 22, which alternately sends signals of duration n-N cycles from each of its outputs on the second entrance

On time diagrams (FIG. 5), the following sequences are presented: (N groups of n clock pulses sent to lines going to M controlled objects (a), signals at the outputs (first and NM) of counter 18 (b), signals at the outputs ( the first and M-m) of the second distributor 22 (c) and the signals at the outputs of the first distributor 23 (g).

side 1 of the device operate synchronously and in phase with the first distribution

is divided into 23 and the counter 18 of the receiving side,

During the first cycle of operation of the distributor 8, the signal from the first output of the counter 7 allows the output through the group of elements 12 and elements 10 OR to the second inputs of the elements 3 and 3 information (signals) on the state 3 12821 scientific research institutes of the first group of sensors 4, and the signals from the outputs the distributor 8 provides alternate transmission of information about the state of the sensors through the elements AND 3 and further through the element OR 5 5 and the transmitter 6 into the channel going from this transmitting side to the receiving side.

At the end of the first transmission cycle

the signal from the output of the distributor

8, the counter 7 changes its state and, using a signal from its respective first output during the second cycle of operation, the distributor 8 permits the transmission to the channel of signals about the state of the second group of 4 sensors of this transmitting part. During the last N-ro cycle, the signal from the output of the counter 7 allows the state of each of the sensors of this group to be output via the AND 121 group of elements, which through the OR 10 elements and alternately through the 3 And elements and then through the 5 OR element and the transmitter 6 into the channel, after which the distributor 8 and the counter 7 are reset. The transmission of signals from this transmitting side is stopped until the next sequence of N groups of n clock pulses arrives at receiver 2. at the time of the survey of the state of the sensors of individual controller objects.

Thus, in the period of one (for example, the first) cycle of operation of the tap 18 (or, equivalently, during the first N cycles of operation of the first distributor 23), a sequence of N groups of n clock pulses and receiving from it information about the state of the sensors of this object, arriving at the receiving point via the channel, and from the channel via receiver 17, to one of the inputs of the OR 16 element. At the same time, during the first cycle of operation of the first distributor 23, when the counter 18 and the second distributor 22 issue The signals in control unit 19 from their first outputs, receiving the first line of the state information, sensors of the first group 4 of the first transmitting side, and among them the first sensor, are a signal of a generalized signal.

If the first sensor of the first group of 4 sensors of the first object is in the state O (On), the first sensor is sent to the dispatch point corresponding to a logical zero. This signal, arriving through the element OR 16 and the element NOT 28 at the input of the element AND 26, together with the signals arriving at the inputs of the same element AND 26 from the first output of the paired group of outputs of the control block 19 and the first output of the distributor 23, evoke the output element 26 of the signal, which sets the trigger 32 in the indicator 15 parameters to the state O, which corresponds to the quenching of the Avariya indicator (or 1 and the inclusion of the indicator OK).

In the event of a malfunction, for example, the N-ro set of equipment in the first object at the first position in the NM cycle of a sequence of characters transmitted from this object is transmitted logical 1, which, acting together with signals from the corresponding output of control unit 19 and from the second output of the first distributor 23 to the inputs of the element I 25, causes the appearance at its output of a signal setting the trigger 27 to state 1 and the ignition of the Avariy indicator for the N set of equipment of the first transmission side.

If it becomes necessary to check the status of all sensors of the N-ro set of equipment to this transmitting side (for example, when identifying the causes of the Avar signal), then using a switch

29, the first output of the control unit 19, connected to the third input of the sensor state indicator 14, is connected to the output of the corresponding (N-ro) element 31. The output signal of this element 31 appears during and for the time during which the input of the sensor status indicator 14 from the output of the element OR 16 receives signals corresponding to the state of the sensors of the N-ro set of equipment on this (first) transmission side, resulting in signals from the second outputs of the first distributor in the NM cycle trigger 27 in the indicator 14 not d tchikov

the signals from the first redacted set of equipment were recorded.

The time diagram (Fig. 3D) shows a sequence of signals from the output of the element OR 16 to the input of the indicator 15 parameters and the input of the sensor status indicator 14 and the corresponding information about the state of (first, second, (nl) -ro and n-th sensors of the first and N-ro sets of ar {paratura on the first transmitting side and the same sensors of the first and N-ro set of equipment on the M-th transmission side.

The diagram (Fig. Ze) shows the signals arriving at the RS input of the flip-flops 27 (memory elements) in the indicator 15 parameters from the outputs of the AND elements 25, which separate the signals 1 (Avari) coming from the first and N-ro sets of equipment of the first object and the first and N-ro sets of equipment of the M-th transmitting side.
