The drawing shows a structural electrical circuit of the proposed system.

The system contains a PB PBX consisting of matching blocks 1, counters 2, a generator of 3 signal groups, a connection block 4, a block of 5 sensors of reference values, an analog-code converter 6, a compensation block 7, a load threshold control block 8, a read block 9 , decoder 10, transmitter 11,

25 pulses as well as junction station 26 and CA 27.

The device works as follows.

At the CA 27, a sync signal section, pre-. which is a sinusoidal voltage frequency from 100 to 200 Hz. From the first half-wave of this segment

0 sync signal on MS 26 a pulse is formed, under the action of which CSS

26 connects the CA 27 to one of the PB PBX, which begins to receive the specified segment of the clock signal from the second

5 half waves of which block 15 SB ATS forms and pulses, installs block 16 to its original state 1 of. At the same time, block 15 turns on block 14, which of the denials: x half-wave

0 the following periods of the clock generates clock pulses received at the input of block 16.

Block 16 generates a sequence of pulses, the first of which

5 enters the decoder 10 to convert the code, the second to block 9 and TptTbH controls the operation of blocks 4 and blocks 5, which in turn connects 6 to the converter in turn

0 circuit of registration of loads to the block 8 sensors of reference velgchin. The information inputs of counters 2, block 22, block 8, converter 6, and sensor 13 are interrogated so that when reading information from them, eight elements of code combinations are formed, where the eighth character is a parity check generated by block 23. As a result, the read results

0 when receiving a CA 27 image, that information packet, where the first byte is the beginning of the packet, the second is the PBX number, the third is the operating mode of the PB PBX, the fourth and all others are informational. The number of each byte, counted from the beginning of the packet, determines the type of information. CA 27 contains a similar block 15 and block 16, working synchronously and in phase. The accepted first three combinations are alternately compared to the reference ones, while the rest are checked for parity or sludge can be checked for various other signs (for elevation, compliance). When a failure is detected, the CA stops sending the clock signal and, depending on the program, switches to the next PB of the PBX or re-polling this one, by means of CM 26, by sending short segments of the clock to the block 15, running without receiving and polling other PB PBXs in which In this case, the pulse of the end of the cycle into the shortened segment of the clock signal is not formed and the blocks continue to measure and accumulate information until the next full read cycle is completed. The system is designed to operate in two modes, Control and Measurement. In the Monitoring mode on the CA 27, only emergency, real time information and cases of exceeding the threshold values of monitored values are given. In the Measurement mode, at the CA 27 during the polling period of this PB PBX, the current values of all measured values and the state of all monitored points are sequentially transmitted. To transfer the PB PBX to the desired mode using the block 17 and to control the technological equipment of the PBX using the former 19 Controllers 27 generate and transmit control signals and strictly determined moments of the SAT PBX polling cycle, which is ensured by the common-mode operation of the control units in the SSS 27 and SAT PBX. System operation in the Control mode. During the period between calls to this PB PBX from the CA 27 from the generator 25 through block 17, block 16 operates, controlling the operation of blocks 4 and block 5, converter 6 and block 20. At the inputs of matching blocks 1, block 22 and blocks 4 receive discrete, digital and analog signals, respectively, which are accumulated in counters 2, converted in block 22, measured and compared with threshold values in block 8. In the absence of signals at the output of these blocks, block 20 constantly circulates these outputs, disables the code pattern corresponding to the number at the PBX in the sensor 13. The CA 27, referring to this PB of the PBX, transmits to it a clock signal, through which the block 16 through block 9 connects to the decoder 10 a code combination of the start of the packet in the sensor 13 of the service combinations. After sending and receiving to the CA 27 of the beginning of the packet, the CA continues to poll this PB PBX in order to determine the PBX number. But since block 20 continues to search for information, keeping the combination of the PBX number in the on state, the CA 27, not detecting this combination, stops sending the clock signal and after 40 m / s sends the next segment of the clock signal to the DC 26. The beginning of this clock segment is sensed by the CSS 26 as a command to move to the next SB PBX. If there is no information to be transmitted on all the station blocks connected to the MS 26, having received only the package start combinations that indicate the functionality of the PBX, the node block will return, for example, to the first station block. Suppose that by the time of the survey of this block, its blocks 8 and the counters 2 were recorded in a number of inputs. Block 20, having detected this fact, stopped at the output of counter 2, from which the signal of the first one arrived, prepared for transmitting the code combination of the PBX number in the sensor 13 and through the driver 3 connected to block 9 a group of outputs, to which the outputs with information about transcend. When a sync signal arrives on this PB PBX, the code combination of the beginning of the information packet is polled and transmitted, then the PBX number and, finally, the status of the connected output group is read. The total number of groups is sixteen, the number of outputs in each is twenty eight, groups are formed by shaper 3, and the result of polling groups with regard to the address takes seven bytes. The end of the polling of this group of outputs of the CA 27 proceeds to polling other PB PBXs, and block 20, by the signal of the end of the read cycle, corresponding to the meager beginning of the pause in the transmission of the clock voltage, finds the next group of outputs containing information about the transfer, etc. in the Measurement mode by a signal from block 17, a command is issued to shut down block 20, generator 3 and block 8. At the same time, generator 25 is turned off, which is used in Control mode to operate the measuring and control blocks, and the output of converter 6 is connected to block 9. At the moment The call of the CA 27 to this PB PBX in the Measurement mode is alternately but all the outputs of blocks 2, 22 and 6 are polled, and the information packet is 128 bytes. Discrete signals from the equipment of the PBX and from the sensors of the special alarm system are fed to the inputs of the matching unit 1, where they are normalized and transmitted to the counters 2, the outputs of which are connected via the driver 3 to the PBX, containing digital information, and its control These inputs are connected to block 22, where this information is converted and fed through shaper 3 to block 9. Finally, load detection circuits and various sources of analog information are connected through blocks 4 to converters. For the initiator 6, the outputs in the Measurement mode through the shaper 3 are connected to block 9, and in the Control mode they are connected to block 8 i where they are compared with the reference values generated by block 5. The read results in both Rusins from the output of read block 9 are received to the input of the detector 10, to the transmitter 1 and further through the signal output unit to the line When transmitting commands to control the mode of the SB PBX unit and the technological equipment of the PBX, the principle of time division is used. The control signals are received by the receiver 18, converted into pulses of a direct current and are fed to the input of the former 19, controlled by block 1. Thus, the speed of the proposed system is improved. 1.
