FIG. 1 shows a functional control circuit (PU) of a complex telemechanical device; see 2 - the half set of a corovable item; in fig. 3 that block - control of the teleinformation (TI); in fig. k - the same, the control unit of the code receipt. The half-set PU includes a linear block 1j switch 2 linear pulses, block 3 linear voltages indicator 4, block 5 for setting and executing commands, block 6 for entering numbers. data, TI information control unit 7), indicator 8, indicator 9, distributor 10, control unit 11, code receipt, decoder 12, indicator 13, AND clock pulses, linear pulse shaper 15, conjugation block 16. 8 KP half-set includes call block 17, mode selection block 18, pulse distributor 19, alarm 20, first telecontrol unit 21, second telecontrol unit 21, first sensor 22 second sensor 222. Block 7 contains elements of comparison 23-25 for a forbidden combination; elements 2b and 27 of comparison for single failure and elements 28 and 29 of comparison to the switching zones. Moreover, schemes 23 and 2b constitute the chain of comparison of the decade of units, elements 2, 27, and 29 constitute the chain of comparison of the decade of tens, and elements 25 and 28 constitute the chain of comparison of the decade of hundreds. Block 11 of the code receipt control box contains elements of comparison 30 33, respectively, on the overlay, on failure, on the absence of connection of the object, on a short circuit in the communication line and on the comparison circuit 3. The device works as follows. The device is controlled by block 5 of the task execution task. The linear voltage unit 3 produces linear DC voltages, which are sent after a pulse switch in the switch 2 linear pulses to the communication line. Using the digital input blocks 6, the number of the called object is dialed. The object number consists of four digits of the decimal system. The first three digits carry the KP address information, the last fourth digit identifies an object located on the KP. Each control unit can have two objects of control and management, therefore the last quarter figure can be either 1 or 2. Information about the number of the called object is supplied to the indicator k and the pulse shaper 15. After a complete set of the address of the object, in block 5 of the task and execution of commands, a signal is given that the address is typed. From block 5, the task and execution of commands in the functional blocks of the device are entered into the mode indicator. The block 1 of clock pulses produces a set of clock pulses necessary for the operation of the functional blocks of the device. The pulse former 15 generates the duration and polarity indications of the pulses sent to the communication line through the commutator 2 pulses. The switch 2 pulses in accordance with the entered features. clocked switching of power sources via block 1 to the communication line. After passing the ringing impulses to receive confirmation of the call's correctness, a sequence of read pulses of the code call of the called object is sent to the communication line. In the case of a closed current circuit in the half-set of the controlled point, at the given reading cycle, block 1 fixes the signal 1 and, accordingly, in the case of opening of the current circuit. Thus, the response to the PU is obtained simultaneously with the request. The current information received from the called object is allocated by block 1 and fed to the distributor 10. From the output of the distributor 10, the code information is fed to block 3 by block 1 by selecting the received signals by energy, as well as by reading. short sync pulse after completion of transient processes in the system, which increases noise immunity. From the output of the distributor 10, the code of address information enters block 11. A code receipt is generated in the correlation code, where an inverse check bit is added to each information bit. For example, the receipt code presented in binary form as the number 1010 (which corresponds to the number 10, the correlation code will be 10 01 10 01. In the mode of analyzing the reliability of the code receipt, the information and check bits of the code receipt are sequentially recorded in the cells of the distributor 10. From the information output of the distributor 10 (FIG), the information input of the code receipt enters the information input of the block 11. From the control output of block 10 to the control input of block 11, the check bit of the code receipt is received. Both bits are fed in parallel to the inputs of the first 30, is Top 31, third 32 and fourth 33 comparison elements. The information bit of the code also arrives at the information input of the comparison element, the control input of which receives a signal from the output of block 5 for setting and executing commands. In the first 30, second 31i, third 32 and fourth 33 comparison elements, a differential analysis of the code information received from the object is performed. Namely, in the first element 30, a comparison is made for the presence in the information and test code of the code receipt of type 11 combinations. In the presence of such combinations, the signal from the output of the first analysis circuit is fed to the input of block 5 and to the input of indicator 13 and is identified as a superposition of code receipts, which means that several objects are triggered. In the second element 31, a comparison is made for the presence in the information and check bit of a code receipt of combinations of type 00. When such combinations are present, the signal from the output of the second comparison element is fed to the input of block 5 and to the input of indicator 13 and is identified as a code receipt failure, which means a code receipt distortion caused by interference on the communication line or a malfunction of the receiving equipment. The third element 32 is triggered if all the combinations of type 11 are in the information and check bits of the code receipt. The output signal from this circuit is identified in indicator 13 of the reasons for the code receipt failure and in block 5 as a short circuit in the communication line. The fourth element 33 is triggered if the 8 information and check bits of the code receipt all combinations are represented as 00. The output signal with this element is identified in the indicator 13 for the reasons for the failure of the QC and in block 5 as failure to connect the called object to the communication line, or break in the communication line. In the comparison element, the code information about the address of the called object is compared with the number of the called object entered in the digital data input unit 6. If the address information code of the called object received from the object absolutely coincides with the object number code dialed in the digital data input block 6, the Call Confirmation command is generated in the comparison element 36. From the output of the comparison item, the generated command goes through block 5 to the indicator k. If the code information of the address received from the object does not match the number of the called object entered in block 6 of the input of digital data, then in the comparison item 3 the Not Acknowledgment command is received, the incoming also on indicator 4. If the code receipt is distorted and the reason for the failure on the indicator 13 is displayed and if the object’s call is not acknowledged from the output of block 11, the input of block 5 receives a signal stopping the device until the operator makes a decision. If there is no distortion of the received information and the Confirm Call command is generated, the device continues to work normally with the called object. The interface unit 16 transmits an address code and a sign of the vehicle caused by the object through the interface channel for processing and display. In TI mode, the pulse shaper 15 forms a sequence of polling pulses in the communication channel on each. raz de TI. In this case, similarly to the code receipt mode, block 1, on the basis of a clock pulse, extracts current information in the channel corresponding to a logical 1 or O for a given bit. The read information is sequentially recorded in the distributor 10, broken into it, for example, into three decades of units, tens and hundreds (for example, five digits per decade and, in the form of a parallel code, is fed to a reliability analysis in block 7. In elements 23-25, comparisons of decadal units, tens and hundreds, respectively, are analyzed for the presence of forbidden combinations in the code. In the absence of forbidden combinations, decades of units and tens are analyzed for a single failure in elements 26 and 27. The CL of this code combinations of a decade of units and tens from the output of elements 23 and 2k to forbidden combinations are fed to the inputs of elements 2b and 27, respectively. If the structure of the received code is such that the code combinations corresponding to the same numbers in even and odd decades are different, then in order to increase the reliability of the received teleinformation, it is necessary to reveal the correspondence between the lower decade digit and the parity of the higher decade. To do this, the second information inputs of the elements of comparison 26 and 27 are given the parity signal of the high decade from the output of elements 2 and 25 to the forbidden combinations of the high decades. If in any of the decades a prohibited combination or a single code failure occurs, then each comparison element that has detected a failure gives the TI code failure characteristic indicator 8, the characteristic for it, the signal and the TI code failure type — Disallowed combination, or Single failure. . If in the Even and odd decades of the TI code there are matching code combinations, such single distortions in the above elements will not be detected. Such single distortions are detected when compared to switch zones. Thus, for example, changes in the highest decade of the code are possible with the code values of the lower decade O and 9. A change in the higher decade of the code for other values of the lower decade of the code is considered a failure. To detect such faults, block 7 introduces elements 28 and 29 into the switch zones in the older decades. The first information inputs of these elements are the code of the decade of tens and the code of the decade of hundreds from the elements of the previous analysis. To the input element 28 from the output element 25. To the input elements 29 from the output element 27. The second information inputs of elements 28 and 29 receive signals from the outputs of elements 27 and 28 about the presence in the lower decade O or 9 of the zone of possible code change in the erased decade. Elements 28 and 29 on the switch zones capture the code changes in the senior decades, and if changes in the code of the senior decade occur outside the zone of a possible code change, this change is considered a failure. The signal is fed to the indicator 8, where the character of the failure is highlighted in the indicator of the corresponding decade. Moreover, based on the fact that xa, the pattern is checked in the TI mode, the reasons for TI failure are identified. For example, a continuously repeating single failure of the TI code in one of the decades is identified as a malfunction of the sensor of this decade on the control panel and is displayed on the indicator 8. Non-repeated single faults are identified as interference. pm. and is displayed on the indicator 8. To selectively call an object, a call block is used in each half-set of the controlled item. containing four selective call impulses. After selecting the desired CP, start up with a pulse distributor that has twelve states, and one of two objects of the controlled point is selected with simultaneous activation of the code receipt mode. The shift of the pulse distributor is made by changing the polarity of the voltage of the remote power supply, whereby a current is generated in the communication channel for each code receipt. ; After the code receipt mode, the telegram from the control panel switches on the tele-measurement mode of the previously selected object. At each step of the distributor, the current information of the TI bits is formed in the communication channel, similarly to the code of the receipt. At the appropriate clock of the distributor, according to the commands from the control panel, the DUT mode is activated. An active alarm signal is generated in the emergency mode. After receiving the signal of Avari on the PU, signals are formed in the communication channel, similar to those of the code receipt mode signals. The address of the emergency facility is determined by the receipt code received on the PU. . The emergency state of the object is remembered and is further confirmed only when the object is individually called. In the proposed device, the reliability of the call and the accuracy of the TI code is realized by the hardware of the control panel without installing devices to increase the reliability on the control panel. This is when a large number of KP in the system, significantly reduces the number of equipment and,. therefore, reduces power consumption and improves device performance. These indicators are particularly significant for energy-unavailable and maintenance-free KPs dispersed over long distances. Differential analysis of the TI code and the code receipt for reliability and the inclusion of fail indicators allows you to display the previously processed data (telemetry parameters and remove the cause of the error. This increases the accuracy of the displayed information. The results of preliminary tests showed the following parameters of the reliability of information transmission, the probability of transformation of the television signal10, the probability of not detecting an error in TI - 10 These parameters of reception reliability Satisfy the requirements of GOST 16521-7. In addition, the analysis of the received information to determine the cause of the error and the indication of the cause of its occurrence allows you to quickly eliminate the fault, which significantly reduces the maintenance time of the telemechanical system.
