Abstract

This invention relates to automation and computing. The purpose of the invention is to reduce the amount of equipment. The control test of the device consists of fragments, each of which is displayed on the screen depending on the state of the corresponding nodes of the device. The goal is achieved by the fact that fragments of the control test are sequentially displayed first on the screen of one of the on-screen consoles (EP), and then on the screen of the other, etc. At the same time, on the screens of other EPs the same basic fragment is displayed, which is formed by one simple display mode. This mode can be simultaneously executed on several EA. Thus, the check of the EA is performed alternately by visual analysis of the execution of all fragments of the control test. The end of checking one transponder and the transition to checking the next is determined by the signal that forms at the moment of the completion of the last fragment in the test. This makes it possible to reduce the individual equipment for testing the ES and the tested ES with the help of the equipment common to all ES. To reduce the amount of equipment when checking the operating modes of the light pen, a stop sign detection register is entered, in which each bit is set by a detection signal from the light pen of the corresponding EP. When the bit is set to "1", the operation of this EA is stopped, which makes it possible to identify the detected image element relatively simply and to make the transition to the specified test test area. The display consists of an image processor, a state register, a group of screen consoles, blocks of buffer registers and variable information registers, a fragment ROM and a characteristic ROM, a pulse distributor, a control information control unit. The control information control circuit diagram has been simplified and the stop sign detection register and switch unit have been entered. 3 il.

The display works as follows.

In the operating mode, a working image is displayed on the screen, which the operator can change with the help of the input device, the PC, which is part of the on-screen remote, and to have a dialogue with the computer. In the monitoring mode, automatic diagnostics of the main components is provided with the display of the diagnostic results on the indicator screen. In the control mode, the automatic control system (NAC) starts up, which is made up of the control information output control unit 19, the stop sign register 17, the switch block 18, the fragment ROM 14, the variable information register block 16, the sign ROM 15 and the control test program recorded in ROM of 14 fragments and ROM of 15 signs.

The NAC allows you to test the functionality of a graphic display in almost all modes of operation, except for communication with a computer channel.

The control mode is turned on automatically if the following conditions are met, determined by the information in the register 2 of the console state: there is no indication of image regeneration for the given EC, which is activated by a signal from the computer; there is no test recording signal from ЗП12 (signal - REC.); no signal RAB-A - i.e. the display is not in computer mode. This mode always occurs after power up. The operator at any time can turn off the regeneration and thereby turn on the control mode. In order for the monitoring mode not to be turned on during the change of commands coming from the computer (at this time the RAB-A signal is removed), it is necessary to turn off the RAB-A signal for about 30 ms using a single vibrator 41 and the element OR 37 (fig.Z). To debug programs and troubleshoot the display, it is possible to read information from the memory (from memory 10 or from ROM 14 and 15) in a one-time mode, which is activated by pressing the switch on the EA keyboard 12. When turned on.

This switch is given a ONE signal to the input of the AND 34 element. Since. in the one-time image generation mode is turned off, then for a single readout of data from the memory unit 10, the monitoring mode is removed by the indicated ONE signal. A single reading from the ROM 14 is performed if the Control signal arrives once (with the switch of the same name turned on) to the input of the AND 40 element (FIG. 3). All of these signals are received on line 51 from register 2 coc. either the remote.

A test program (a program of reference images and their transformations) is recorded in the ROM of 14 fragments and a ROM of 15 features. In the fragment ROM, a program is written, similar to a normal internal program, taking into account the composition of the internal commands of this type of display. In the feature ROM 15, control codes are written, with which the NAM operation modes are switched and the register (word) address in block 16 of the variable information registers is determined.

The codes in the ROM of 15 features determine the following main modes: enabling the operation of the block of 16 variable information registers and prohibiting the operation of the ROM of 14 fragments; turning off the ROM 14 and unit 16 and enabling the operation of the memory 10 for the duration of the action of the microcommand obtained from the ROM of 5 microcommands; turning off the ROM 14 and unit 16 and enabling the operation of the memory 10 for a while until the end of the next firmware; permission to write to memory 10 in a read cycle of 14 fragments from the ROM; end of test program.

The modes of operation of the memory blocks (memory 10, ROM 14) are determined by the operation of the trigger

writing the coordinates of the beam, recording constants, tracking, etc.), then to ensure the operation of the fragments of the test program in which such commands are available, a limited-capacity memory is connected in parallel to the fragment ROM 14, into which information can be written and read. As such a memory, a block of 16 variable information registers (FIR) is used.

Thus, in the device, two memory systems 5 are working in parallel, working on the memory unit 10 and the control consisting of the ROM of 14 fragments, the ROM of 15 features and the FIR unit 16. In the control mode, if the triggers 43 and 44 are turned on in block 19, the output to the digital bus 68 of the memory device 10 is closed and the receipt of information to the digital bus from the ROM of the 14 fragments and from the FIR block 16 is allowed. If, in the monitoring mode, the recording mode is turned on, information from the number bus 68 is recorded in the FIR at the address read from the 15-character ROM. It is possible to record and read information in the control mode of the memory 10. This is provided by signals; 1 is when you turn on the flip-flops 43 and 44 in block 19. This allows you to switch from the control program recorded in the ROM 14 to the addresses of the specified portion of the memory 10, in which information that supplements the reference image on the screen can be recorded and read. In particular, in this mode, you can check the input from the tablet. In this, the controlling part of the program for working with the tablet is recorded in the ROM 14, and the information entered from the tablet is recorded in the selected zone of the memory 10.

 ditch 43 and 44 in block 19 (Fig. 3), which displays information in the frame, which are included by the signals from the ROM output read from this zone, and from 10

ROM 14 fragments.

The test of control consists of fragments, in each of which a sequence of internal commands forms an image characterizing the performance of one or several device nodes.

Move from one fragment to. Due to the fact that writing to the ROM is impossible, and as part of the internal commands of the graphic display there are commands

The operation of the memory 10 is controlled in the same way as in the known device by means of a signal on the line 59 through the control unit 3.

software module recorded in ROM 14 and 15 The program is constructed so that the fragments are changed automatically after a programmed period of time or when the transition conditions in the program are fulfilled as a result of the operator’s influence on the input devices of the on-screen console 12, for example, when pressing the Light switch button ). After the first pressing of the SRP button, the automatic change of fragments is turned off and restored after a special element of the image formed by the program in each fragment image is detected by the light pen.

If the image on the screen differs from the specified IP, the system does not respond responsively to the control actions of the operator, then this indicates a malfunction of a certain block or node of the display. The localization of the malfunction is performed by analyzing the image on the screen and, if necessary, the program of the corresponding fragment.

The test control program recorded in ROM 14 and 15, one dp of all RFP, should ensure the formation of the image on the screens of all screen consoles 12 of the device. Since in the test program there are internal commands (Jump with return, Jump by code in the iteration register, etc.), the information for which changes during the test, the test for each EA should be divided in time. so that the variable information is remembered in block 16 of the FIR, it is possible to divide these registers among all EPs. However, if the volume of the variable data used in the program increases, the increase in the volume of the equipment of the FIR unit 16 becomes unacceptable.

Experimental verification has established that with automatic fragment replacement, the optimal display time for one fragment is 2-3 seconds. Consequently, the passage of all the fragments on one ES takes about a few tens of seconds. Therefore, it is possible to alternately test all ES on control fragments of the test. As long as an automatic scheme of control fragments is being executed at one of the EAs, the same initial fragment of the test is displayed on the remaining EAs.

commands with variable information are used. Such a program can be simultaneously executed on several EAs.

The end of the test program execution is determined by the code in the ROM 15 with nak. This code generates a signal in the decoder 49 of block 19 (FIG. 3), which through the OR 50 element via line 60 enters the Monitoring input of the switch block 18 (FIG. 2). In block 18, this signal passes through the element OR 29 to the C input of the shift register 30, the number of bits of which corresponds to the number of EP 12 (in particular, the diagram shows a four-bit register 30). The output signals of the shift register 30 are fed to the inputs of the element 31. The signals to the second inputs of the latter through line 57 receive the number of the electronic signature, the duration of each of which corresponds to the connection time of the corresponding electronic signature to the general display equipment. On the EA, dp of which the signal of the ES number coincides with the signal at the output of the shift register 30, all fragments of the test are displayed. During the connection of the remaining EPs, the coincidence on the I-IPAIN element 31 has and a signal appears at the output of this element, which through the element 32 (only in the control mode) enters the register 2 of the console state via line 65 through the input pad 67 This signal creates the conditions for executing a conditional jump command in image processor 1 (in particular, the Go to non-detecting command). Therefore, the program of the original fragment, which ends with the conditional jump to the beginning of the fragment, repeats up to. as long as there is a signal at the output of the AND-OR-31 element.

After completion of the test at one of the EPs, the signal shifts in the shift register 30 and the signal at the output of the AND-OR-NOT 31 element is absent when the EA operates, the address of which is 1 greater than the address of the EP displaying the control fragments. However, if at the output of the shift register 30 a signal appears on the bit corresponding to the number of the electronic transducer, which is not turned on or faulty, then the input of the test 60

In this case, in order to prevent the circuit from stalling, a forced shift register circuit 30 is introduced. For this, trigger 24 is inserted (FIG. 2), which is switched on by a falling edge of the signal (-SLK) having a period of 20 ms, i.e. equal to the duration of one frame of image regeneration. In each fragment, except for the base, for this

The unconditional transition command, which trigger 24 sets to its initial state, must appear. If at EP 12 the program is not executed for some reason, i.e. there is no command of the Unconditional Jump command, then the trigger 24 is turned on when the leading edge of the SINC signal arrives on line 51 from register 2. This signal, after inverting the NOT 27 element, passes through the AND 28 element and through the OR 29 element goes to the shift input register 30. The signal through the element And 28 enters through every 20 ms to the shift of register 30 until the display of control fragments on one of the EP 12 begins.

The trigger 25 and the element 26 ensures the cyclic operation of the shift register 30.

Register 17 serves to stop the display on the EA, on which the detection of the image element of the SP, which is part of the EP controls, was made. Stopping the display is also necessary in order to be able to record the address of the data in the memory 10 defining the detected element. After detecting the stop sign (SP), the image regeneration is turned off, and the address of the detected element is read into the computer. In register 17, a signal is generated that prohibits the display of control information after the signal has been removed. A sign of regeneration on line 54. For this signal Detection of SP from register 2 of the state of EP, one of the triggers 22 is turned on (figure 2), corresponding to the number of EP that is running at a given time (determined by the signal number of the EM at the D-input of the flip-flops 22). While trigger 22 is on,

the duration of the operation of the corresponding EA appears as a signal at the output of the AND-OR-NOT 23 element. This signal is on line 58 through AND 36 in block 19

control information control prohibits accessing memory 10- and ROM 14 via line 59. Triggers 22 are canceled by Sbrs signals or by the Sign of regeneration activation via a line from control unit 3.

The control test program recorded in ROM 14 and 15 is recorded in the codes of the internal commands of the orders of the graphic display in which the automatic control system is installed, in particular the EC7905 EC7980 displays. The program consists of modules providing the display of basic and control image fragments on the graphic display screens, as well as modules controlling the automatic or manual change of fragments.
