The invention relates to automated control systems, in particular, to control systems for digital-analogue analog-digital, digital analogue electronic equipment nodes (REA). The invention can be used to control integrated circuits and functional units based on them (modules, cells, blocks), as well as to adjust them. A software-controlled automated control system of functional units of electronic equipment is known, comprising a program input unit, a control unit, a test set generation unit, a switch unit, a measurement unit, an operation unit, a synchronization unit, a registration unit, a program control unit, a coincidence unit. The system is designed to control the parameters of analog, digital, difroanalog and analog-digital units of REA 1.. The disadvantage of this system is the inability to repeat (looping) any part of the control program, which makes it difficult to use for setting up work, as well as not sufficiently effective self-control of the system, which only allows to control oddness, circulating information in the system without checking health of the nodes included in the system. The closest in technical essence and the achieved result to the proposed is a system for automatic control of parameters containing a control computer connected to a generator of control signals, input and output registers of address, input and output registers of code combinations, a switch connected to analog signal generator, analog signal meter and input code combination register 2. The disadvantages of the known control system are the lack of self-control, which reduces the reliability s control, the inability to stop at a predetermined set prograg 4We and wrap-around any portion of a program that does not allow the use of CEA DLYanastroyki system and novozmozhnost the system with several measuring priboramiodnovremenn but that its use reduces effektivGost. The purpose of the invention is to expand the functionality of the control system and increase the efficiency of its use by introducing new operating modes and increasing the reliability of the control by introducing self-control of the hardware of the system. The goal is achieved by the fact that in an automated system for monitoring electronic circuit parameters, there is an operator’s console that controls a computer, the first outputs of which are connected to the first inputs of the address register block, to the first inputs of the input information block, to the outputs of the output register register , the second inputs and outputs of the controlling computer are associated with the second outputs and inputs of the block of address registers and with the first outputs and inputs of the synchronization block; The outputs of which are connected to the second inputs of the input information registers, to the first inputs of the stimulating signals block, the measuring meters block and the output information registers block, the second inputs of which are connected to the first outputs of the measuring block, second 1 1 and inputs connected to the outputs of the input information registers, with the first inputs of the first switch and the second inputs of the block of stimulating signals, the outputs of which are connected to the second inputs of the first switch, the first outputs of which are connected to the digital-BHjvi outputs systems, second outputs to analog outputs of the system, third inputs to digital inputs of the system, fourth inputs to analog inputs of the system, and third outputs connected to the third inputs of the meter block, mode control block, second switch, reference signal block whose outputs connected to the fifth inputs of the first switch, connected by sixth inputs to the outputs of the input information register unit, to the inputs of the reference signals and to the first inputs of the second switch, the outputs of which are connected to the first the inputs of the control computer, the second inputs are with the outputs of the address register block and with the second inputs of the synchronization block, the outputs of which are connected to the third inputs of the second switch and to the first inputs of the control unit of the relay, the second inputs of which are connected to the second outputs of the block meters, the fourth input connected to the first output of the mode control unit, the third inputs of which are connected to the outputs of the operator’s console, the fourth inputs and the second output to the third outputs and the inputs of the control unit the third output is connected to the first inputs of the controlling computer, and the third inputs of the output information register are connected to the fourth output of the first switch.

Introduction of the above-mentioned blocks and connections allows for effective self-control of the system, covering almost all of its hardware, as well as getting new modes of operation that are absent in the prototype and analogues (shutting down any part of the program, stopping at any given program step, automatic program adjustment) that allows you to use the system not only to control the functional units of electronic equipment, but also to configure them.

Block 1 consists of n identical shapers 15 control cjarHals. The number of drivers depends on the number of standard measuring devices used in the system, included in blocks 7 and 8, as well as the registers in blocks 3 | 1 4, and the information bus width of the control computer. If, for example, the NEC-OZD microcomputer with the information bus width equal to 1b bits is used as the UBM, then one 128-bit register can be controlled with one shaper. Each of the drivers 15 consists of a decoder 16, an element OR 17, and a generator 18 of the confirmation signal (MFR). The block diagram of block 1 is shown in FIG. 2

Block 3 contains n identical 16 bit registers, each of which consists of four 4-bit static registers 19, for example, 133TM5. At the outputs of registers 19, matching blocks 20 are turned on. The type of matching blocks 20 depends on the purpose of register 19. If register 19

is designed to issue digital information to the control object, then the matching unit 20 consists of trunk amplifiers 109LI1. If the register 19 is designed to control the relay inputs of devices included in blocks 7 and B, the matching unit 20 consists of 146KTZ keys. The block diagram of block 3 is shown in FIG.

Block 4 has a similar structure. It differs from block 3 in that the matching blocks 20 consist of open-collector circuits 133La8, the corresponding outputs of which are combined into mounting OR (load resistors are located in the DCU). The block diagram of block 4 is shown in p. four.

The purpose and operation of the blocks included in the automated system

, control, the following.

Unit 1 is designed to generate control signals (Ex. 11. Ex. 8), necessary for recording information in Blocks 3 and 4 for reading control codes from Units 3-5 for controlling the interrupt vector interrupts for Lok 10, for organizing interrupts to start devices entering b blocks 7 and 8. Decoder 16 decrypts the lower bits of the addresses coming from block 5 and bbtuaipt control signals (control 11 ... control 8 p) on blocks 3, 4, 7, 8, 10, and the second switch 11. The leading address bits are decrypted in a buffer block (not shown) and serve to select the number shaper 16. Signals for tracking information (SPRO and type of exchange (TS)) come from UBM 2. A DSS signal indicates the reliability of the information being provided, and the TO signal determines what information is currently on the highway (address or data). In response to The DSS signal, the shaper 18 generates and outputs to the UVM 2 an MFR signal, which notifies the UVM 2 and that the corresponding control signals are generated. The MFR signal is delayed relative to the DSS signal by the time determined by the QS circuit elements (0.5 - 1 μs). At the outlet, the former 18 included elements with an open collector, forming an assembly OR. UVM 2 is designed to control the operation of the system. Unit 3 is designed to record and store current codes of digital signals applied to the control object as well as digital codes controlling the operation of the first switch 6 and blocks 7, 8, 12. The information is recorded in unit 3 from the address information bus UVM (0 ... 15 p SAD) via buffer amplifiers (not shown) under the action of control signals Ex. 11 ... Controls, received from the unified emergency control unit of block 1. Block 4 is designed to receive and output to the CCTV OUTPUT1X digital codes of the control object, as well as digital codes corresponding to the parameters of the control object measured by block 8. Control signals Upr.31. .. Upr, 5 are received from the corresponding outputs of the shapers of block 1.1. . .m switch bits come from the corresponding outputs of the first switch 6 (in Fig. 1c the fourth outputs of the first switch), 1..N bits of the meas. arrive from the corresponding outputs of block 8 (in Fig. 1c the first outputs, block 8). Unit 5 is designed to store address codes if the address bus. The UMB 2 is aligned with the data bus, such as, for example, the microcomputer Electronics NTs-OZD. The information is recorded in the address register by signals from the PRL and TO, coming from the ACU 2. The imager 18, which is part of block 5, delays the AC signal for a time of 0.5–1 µs and sends it back to the CCM 2 as a signal The MTR, which informs the UBM 2 that the transmitted information (address) has been received. The first switch 6 is designed to switch the inputs / outputs of the control object to the corresponding outputs of block 3, to the corresponding outputs 1 of block 7, to the corresponding inputs of blocks 4 and 8, and also to switch the sixth inputs of the switch to its fourth outputs and its fifth inputs to its third devices for self-monitoring of the system. The relays included in switch b are controlled from the switch register, which is located in block 3.- With the help of petoe group 26, the digital inputs of control object 9 (OK) are separated from all other circuits. If the contacts of the relay 26 are in the upper position, then the data of the circuit OK are digital inputs and the digital information from the corresponding register of the block 3 is fed to the corresponding contacts of the OK. If the relay contacts are in the lower position, then the corresponding OK circuits can be either analog inputs and outputs, or digital outputs. Moreover, if these are digital outputs, then the contacts of the relay group 27 are in the upper position, and the contacts of the relay group 28 are in the lower position. In this case, information from the digital, OK outputs goes to the corresponding register of block 4. If these OK networks are analog inputs or outputs, the contacts of the relay group 27 are in the lower position and these OK networks are connected to connectors 25 and further to the relay group 23. Using relay groups 22 and 23, as well as connector 25, you can connect any device in block 8 to any analog output OK. You can also connect any device entering block 7 to any analog input OK. Relay group 28 is intended for switching information and block 3 to block 4 in self-monitoring mode. With the help of the relay group 25, the outputs of the stimulating devices included in block 7 are connected to the inputs of the measuring instruments included in block 8 in the self-monitoring mode of the system. Block 7 is designed to send stimulating signals to the control object, and block 8 to measure the output signals of the control object. Measuring inputs (Vm.iz.) Using the switch 6 are connected to the desired outputs OK. According to the Start signal supplied from block 1, when 6op measures the signal received at its input. At the end of the measurement, it acquires a signal (Cont.), Necessary for the transition of UVM 2 to the processing of measurement results. The measurement result is output in a binary-decimal code to the special outputs and, through block 4, enters the ACU 2 for processing. To synchronize the oscilloscope 32 by block 10, a special sync signal is generated. , the formation principle of which is shown in fig. 9. Block 10 is designed to transfer the operation of the ACU 2 to the mode processing program dialed on the console 14 to exit the CCTV 2 on the self-control program during the measurement of parameters by block 8, to form an oscilloscope synchronization clock in the looping mode of the control program. Consider the operation of block 10. Example. Let an external request for an interruption of the PDL-1 HNSH corresponding to some mode of operation of the system be received from the console 14. This signal, having passed through all the formers 33, will go to UVM 2 in the form of an SZP1 signal. In response to this signal, the UVM 2 outputs the RZR1 signal (resolution), passing through the sequentially connected shapers 33 will reach the shaper to which the external request signal arrived. Further propagation of this signal is blocked by a request signal coming from the output of element 38 OR of this shaper 33 to prohibit entry of element 35 prohibition. These signals (request and resolution) through element 36 AND activate shaper 37 interrupt vectors, provided that the line is free signal Zan This is absent), generates an Interrupt signal and an interrupt vector in UBM. The interrupt vector is the address of the memory location in the memory of the ACU with the start of the program corresponding to the mode set on the remote control 14. The encoders of all the formers 37 are hardwired with two interrupt vectors (to organize the modification of the modes). The number of the vector is selected using a control signal from block 1. Interface signals, for example, Zan, are supplied according to a standard organization scheme, the exchange between CCL 2 and external. devices. After receiving the interrupt vector, the UBM 2 proceeds with the execution of the program corresponding to the specified mode. As soon as all the preparatory operations on the control signal from block 1 are completed, one of the measuring devices will start measuring the corresponding parameter; OK The measurement time is from 10 ms to 1 s, which is many times longer than the information processing time in UVM 2. Measurement of UVM 2 is required for other tasks, such as managing the self-control of the system or preparing new measurements. For this, the control signal for starting the meter from block 1 is also applied to the corresponding driver 33 and generates an interrupt request. Upon receipt of the resolution from UVM 2, an interrupt vector is generated and the UVM 2 proceeds to control the process of self-monitoring or the preparation of subsequent measurements. As soon as the measuring instrument finishes measurement, it generates a signal about the measurement, which enters the external query circuit of the corresponding driver 33. The drivers connected to block 8 of the meters have a higher priority than the drivers connected to the console 14. Therefore upon completion of the elementary exchange act, the UVM 2 returns to the execution of the main program, i.e. it receives information from the measuring device, processes it, enters the result if necessary, proceeds to the next set programs for organizing Stop modes on a given set, Looping a program section, as well as synchronizing an oscilloscope with any program set in Looping mode, block 10 includes a binary-decimal counter 39 sets, comparison blocks 40 and 41, and synchronization pulse generator 42, consisting of elements 51 and resistor 52 and a capacitor 53. At block 41, the switch 14 of the console is given the binary-decimal code of the dialing number from which it is necessary to return to the desired set of programs. As soon as the current dialing number in the counter 39 coincides with the number dialed on the operator’s console 14, the block 41 issues a request signal arriving at the DPR1 line of the driver 33 (FIG. 8). Further, the standard procedure for generating an interrupt is performed, and the WLM 2 proceeds to processing the looping mode. At the same time, the number of the set from which it is necessary to begin the repetition of the progilm is recorded in the counter 39 by the control signal supplied to the input C2 from block 1. Next, the counter 39 performs the binary-decimal counting on the signal supplied from block 1 to the input C1, and counts it again to the same set, etc. At the same time, as soon as the current dialing number in the counter 39 coincides with the number dialed on the remote control 14, the block 40 and the shaper 42 produce a sync pulse that can be synchronized by the oscillograph 32 included in the block 8. Thus, on the oscilloscope screen you can watch steady picture, you do any place of the program. Similarly, the Stop mode on a given set is implemented. It also proceeds to a subroutine, the result of which M is stopping. Unit 12 is designed to organize self-monitoring system. A power source 46 with a controlled voltage divider 47 is designed to test a DC voltmeter 30. Other sensors may be included in the unit depending on the component of the unit 8. During operation of the system, unit 12 is periodically checked. The device works as follows. The information stored in the storage device. The CMU 2, in accordance with the monitoring program stored there, is transmitted to the information inputs of the block b, where it is recorded by the control signals from the ACU arriving at the control inputs of the block 5. Information from the output of the block 5 post PA NA. the second inputs of block 1, where Dv is encrypted. On control signals from the outputs of block 1, information is recorded in block 3, designed to emit digital signals through the first switch 6 to the object 9 of the counter (L, to set the operating modes of block 7, to select the limits and the nature of: -8 block measurements, for controlling the first switch b to select the operating mode of the block 12. Digital data from the output of the control object 9 through the first switch b are fed to the third inputs of the block 4. From the outputs of which they enter the ACU 2 for processing in accordance with the control program Block 7 through the first The switch 6 outputs the necessary analog signals to the analog inputs of the object 9 of the monitor. The response signals from the analog outputs of the object 8 of the control through the first switch 6 are received from the 3 (third) inputs of block 8, where they are measured and in accordance with the control program. are converted into digital form and from its first outputs are fed to the second inputs of block 4, from the outputs of which are transmitted to the ACU 2 for processing. Unit 1 generates, in accordance with the control program, the signals intended for the synchronous operation of all units of the system. Block 10 is designed to organize the following operating modes of the system: 1) automatic one-time check with fixation of the result) checks on the output device (for example, display or konsul) without osTanov in the presence of failures in the control object; 2) the same, with osanovom after each failure; 3) step-by-step operation with shutdown after each elementary measurement cycle; 4) automatic one-time check with a stop on any given set of control program; 5) automatic reusable verification by looping any portion of the control program; b) program adjustment mode; 7) system self-monitoring mode. According to the signals from the console 14 and block 1, the block 10 generates and sends an interrupt request signal to the control inputs of the high power input control module 2, and when it receives the permission from the high power input terminal 2, it interrupts it. The interrupt vector is the address of the memory cell in the PSU 2 with the beginning of the program corresponding to the specified mode, and is issued only to the cell to which the request from an external subscriber has arrived. If requests are received from several subscribers, the request from the subscriber with a higher priority is processed. The block has several backup cells for the formation of interrupt vectors, which allows the introduction of new modes of operation or new gauges. The comparing circuit with the driver that forms part of the mode control unit generates a sync pulse as soon as the current program number becomes the same number as -. given by the operator from the console. The second comparison circuit generates the End Dial signal (as soon as the current dial number becomes equal to the number specified by the operator). When the program area is cycled by a signal. The final set is the transition of the system to the development of this mode. The new value of the number set is written to the set counter, from which the loop program will start. Thus, the program will repeatedly repeat from the set recorded in the interrupt set counter to the final set specified on the operator’s console. The second switch I is designed to implement the system self-monitoring during the execution of the main control program of the object. This mode is possible because the measurement time of the parameters of the signals by the block 8 is large compared to the computer cycle of the cumulative control module (more than 1000 times longer). Therefore, during the measurement of the output signal, the block 8 of the cc system 2 performs a control program their connections. According to the signal from block 1 at the beginning of the measurement, block 10 forms a request for interruption and, upon receiving permission from the control panel 2, enters the vector into the control block 2, thereby causing the execution of one of the subroutines self-monitoring. UVM 2 issues control codes for the corresponding blocks of the system- (blocks 5 and 3). From the outputs of these blocks, the control codes arrive at the corresponding inputs of the second switch 11, from the output of which are entered in a certain sequence in the ACU 2 for processing. If the UVM 2 detects a mismatch of any code received from the output of the switch 11 with the reference stored in the UVM 2 memory, the system stops working and the information about the failed unit is displayed on the display device. After the measurement is completed, block 8 generates a special signal, which arrives at the second inputs of block 10. With this signal, block 10 generates the necessary signals to return the ACU to the execution of the main program. The unit 12 of reference signals is designed to complete a system test in the self-monitoring mode. It generates a series of reference constant, variable and impulse voltages, which, in accordance with the program, through the first switch 6 arrive at the corresponding measurement inputs of block 8. The measured parameters of the reference signals are transmitted through block 4. to UVM 2, where they are compared with the reference value these parameters. To check the operability of unit 7, its outputs through switch 6 are connected to the measuring inputs of unit 8. The monitoring process is similar to that described above. In order to fully control switch b, jumpers must be bridged with the corresponding inputs and outputs of the switch (2nd outputs with third inputs and second outputs with fourth inputs). Thus, the control covers the entire hardware part of the system, which significantly increases the reliability of the measurements taken by it. The nporpaMNOJ is monitored using the PSU 2 by checking the checksum of the data. Such control is part of the mathematical system provided by any WLM and does not require an explanation. I / O device is intended for inserting a prog shaft into the memory. . UVM, as well as to display the results of control on the terminal device of the gathering. The use of the invention will significantly expand the functionality of the system. For example, the application of the looping mode of the program allows one to observe the processes in the control object in dynamics with the help of an oscilloscope, which allows one to use the proposed System not only for control, but also for adjusting the REA. The introduction of an adjustment mode greatly simplifies the process of debugging control programs. The system allows you to control simultaneously a large number of measuring and stimulating devices, which significantly reduces the measurement time and improves its performance and efficiency of use. Coverage of the system with complete self-control increases the reliability of control results.
