The invention relates to telemechanics and can be used in telemechanical systems for collecting and transmitting data on the state of communication equipment, for example, at radio centers of field and stationary communication nodes.

The purpose of the invention is to increase the speed of the device.

FIG. I shows the functional diagram of the transmitting part of the device; in fig. 2 is a functional diagram of the receiving part of the device; in fig. 3 is a diagram of a control unit and a sensor status indicator; in fig. 4 is a diagram of a sensor status indication element; in fig. 5 - the functional scheme of the decoder.

The device on the transmission part 1 contains a receiver 2, a distributor 3, a group of elements AND 4, an element OR 5, sensors 6-1, ..., 6-L, a group of elements AND 7, elements OR 8 and 9, a transmitter 10, a counter 11 , switch 12, coincidence block 13, AND 14 and register 15.

Block 13 of the match consists of the elements OR 16-1, ..., 16-p, the group of elements AND 17-1, ..., 17-l, ..., 17-yV -1, 17-L -2, ..., -P.

At the receiving part 18, the device contains receivers 19, the element OR 20, the sensor status indicator 21, the parameter indicator 22, the clock pulse generator 23, the distributor 24, the AND elements 25, the transmitters 26, the counter 27, the distributor 28, the OR element 29, the decoder 30 and control unit 31.

The control unit 31 (FIG. 3) contains M groups of L elements And 32 and a switch 33.

The sensor state indicator 21 (FIG. 3) contains an HE element 34, an M-N flip-flop 35, outputs to 1 or more connected to sensor status indication elements 36, and And elements 37 and 38.

The display element 36 contains the elements And 39, 40 and 41, the pulse shaper 42, the triggers 43 and the elements OR 44.

The decoder 30 (Fig. 5) contains a memory element (register) 45 in which the code pattern "End of the interrogation, comparison block 46, buffer register 47 and distributor 48 are permanently recorded. The incoming information is written to the buffer register 47 and then compared with the code pattern recorded in register 45. If the combinations are the same, a signal appears at the output of the comparison block 46 and the entire decoder 30.

The parameter indicator 22 is configured similarly to the sensor state indicator 21.

The device works as follows.

From the output of the generator 23 in the receiving part of the device, the clock signals arrive at the second inputs of Eicex elements And 25 and the input of the distributor 24. At each of

the outputs, for example, on the i-th, first distributor 24, the signal appears at the time of polling the state and receiving information about the state of the y-th sensor in each group of sensors of each monitored point. From the third output of the first distributor 24, a signal is output once per n cycles, which is fed to the input of the counter 27 and changes (increases) the counting result by one. Signal on each of the first n

 the outputs of the counter 27, for example on rm, appear at the time and at the time of the survey and obtain information on the status of all sensors (-th group of each of the monitored items. After receiving each N-ro

g of the control signal, i.e., once per l-L clock, the counter 27 from the second output outputs the signal to the input of the second distributor 28 through the OR element 29. The distributor 28 outputs alternately from each of its M outputs signals of duration

0 M-N cycles that arrive at the first inputs of the elements And 25 and allow sequential issuance in each of the lines of sequences from L groups of n clock pulses (signals) in the group.

 A sequence of L-L clock pulses, sent along the line towards the controlled point, arrives at the receiver 2 of the transmitting part 1. The signals from its output during / V cycles ensure that the l-bit distribute Q l 3. The signals from the second output of the distributor 3 at the end of each cycle of its operation (after receiving each lth clock pulse), the input of the counter 11 is received and its indication (state) is changed by one.

5 The distributor 3 and the counter 11 of the transmitting part of the device 1 work synchronously and in phase with the first distributor 24 and the counter 27 of the receiving part 18. During the first cycle of operation of the distributor 3, the signal from the first output of the counter 11, passing through the switch 12, allows delivery through a group of elements And 17-1 and elements OR 16 to the second inputs of elements AND 4 information (signals) on the state of the first group of sensors 6-1

5 of the object being monitored, and the signals from the outputs of the distributor 3 provide alternate transmission of information on the state of the sensors through the elements AND 4 and further through the elements OR 5 and 9 and the transmitter 10 to the line coming from this controlled

0 points to the control room.

At the end of the first cycle of transmission according to the signal from the output of the distributor 3, the counter 11 changes its state and by a signal from its second output during the second cycle of operation of the distributor 3 allows the line status signals of the second group of sensors 6-2 of this monitored object to be transmitted .

If all the monitored objects are used (involved) and all sensor groups are working, then the switch 12 establishes the connections shown in FIG. 1 solid line.

In this case, each transmitting part operates all N cycles and during the last / V-ro cycle transmits to the line information on the status of each of the L / th group sensors (6-L /), after which the distributor 3 and the counter 11 are installed in initial state.

Signal transmission from this monitored object is terminated before the next pulse sequence arrives at the input device 2 (i.e., at the time of polling the sensor states of the other monitored objects).

Thus, in the period of one (for example, the first) cycle of operation of the counter 27 (or during the first N cycles of operation of the first distribution 24), the sequence is transmitted to the first controlled point of the sequence from / V groups according to n clock pulses and receiving information about it from the state of the sensors of this object, arriving at the control room on the first line, and from the line through the receiver 19-I to one of the inputs of the OR 20 element. At the same time, during the first cycle of the first distributor 24, when the counter 27 and the second distributor 28 are output The signals to the control and distribution information 31 from their second outputs are received, along the first line, information on the status of the sensors of the first group 6-1 of the first monitored object, and among them the first sensor, which is the sensor of the generalized signal.

If the first set of equipment of this (first) object is intact, then the first sensor of the first 6-1 group of sensors of the first object will be in the zero state (turned off) and a parcel corresponding to a logical zero will be transmitted along the line in the first temporary position to the control room. This signal, coming through the element OR 20 and the element NOT 34 at the input of the element And 37 (Fig. 3), together with the signals at the inputs of the same element And 37 from the first output of the first group of outputs of the block 31 and the first output of the distributor 24, cause the appearance of the output element And 37 signal. The signal from the output of the element And 37 sets the trigger 35 in the indicator 21 to the zero state, which will correspond to the lamp attenuation of the “Avariya in the element 36.

In the event of a malfunction, for example, the yV-ro set of equipment in the first object at the first position in the / Vth cycle of the sequence transmitted from this object, a logical unit will be transmitted, which, along with the signals from

.V-ro output of control unit 31, -1en and the distribution of information from the first output of the first distributor to the inputs; V-ro device AND 38, causes the appearance at eix) of the output signal setting trigger 35 to one state, and ignition of the “Avariya” lamp for the Lth component of the device of the first controlled object.

If it is necessary to check the status of all sensors. The V-ro set of equipment in this controlled object (for example, to determine the causes of the signal "Avariya), by means of the switching element 33, the output of the block 31 connected to the input of the indicator of 22 parameters, is connected to the output of the corresponding element AND 32. The signal at the output of this element AND 32 appears at the time and during which the signals corresponding to the state of the sensors arrive at the input of the sensor status indicator 21 from the output of the element OR 20. of the first set of hardware on this (first) controlled object, the results of the second outputs of the first distributor 24 in; VM cycle triggers 35 (triggers) in the indicator of 22 parameters will be recorded signals associated with the / V-ro set equipment of the first controlled object.

If at any controlled point not all controlled objects are involved, then they are connected to the sensors starting from the first, and the remaining unused sensors are turned off on the switch 12.

For example, if only one object is currently involved in a controlled item calculated for L objects, it is connected to sensor 6-1, and the remaining sensors are turned off (from Fig. 1, switch 12, dashed lines).

In this case, after the end of the polling cycle of the last connected sensor (generally the / th, and in this case, the first) and after the counter 11 is switched to the next state, the signal from its output is notarized through switch 12 to the inputs of the And 7 elements, allowing reading in a line during the next cycle of a code combination, which is written permanently in register 15.

This code combination is a sign of early termination of the survey of the item being monitored (End of Onros).

At the end of the / - -1st polling cycle (in this example, two cycles, one of which is the transmission cycle of the "Polling End") message, the signal from the distributor 3 that passed through And 14, the counter 11 is reset. Signal transmission from this monitored object is stopped when the next sequence of pulses arrives on the receiver 2.

If during reception the information part 18 from the rd (for example, the first) controlled item is decoded by the decoder 30, the code pattern End Poll will be allocated, the signal from the output of this block will go to counter 27, resetting it to its original state, and through the OR element 29 - to the second distributor 28, switching it to the next r + 1st state. The distributor 28 will begin to issue a signal to the / + 1 st element and 25 and the device will proceed to the survey of the next / + 1 controlled point (in this case, the second).

After analyzing the first position in each cycle of the sequence of n pulses, a trigger 35 with signals from one of its outputs ensures the ignition of the corresponding indicator. In this case, the trigger 43 in the element 36 is set at the beginning of each cycle to the initial state by a signal arriving from the output of the block 31 through the driver 42.

When a signal appears at the end of the polling cycle at the output of the decoder 30 (“End of the poll”), it also enters the inputs of the elements 36 of the indicator 21 (FIGS. 3 and 4). At this point in time there will be a signal at the g-m output of block 31 (for example, at the end of the second polling cycle of the first controlled object, the signal will be output 1-2 of block 31), and the signal from the decoder 30 will go through AND 41, elements OR 44 on flip-flops 43-1-2, ..., 43-1- / V, which flip the vehicle into one state and remove the signal from the inputs of the And 39--2, 40-239 elements - L,. Lamps

"The alarm and the" is properly shut down, and the lamp is turned on "Not activated by the signal from the second output of the riggers 43-1-2 43 - 1- / V.

The signal from the output of the decoder 30 will also go to the indicator 22 of parameters, which will ensure the lamps “OK and“ Avari and lamp ignition ”will not be activated if the parameters of this direction of communication are monitored.
