Description

one

The invention relates to automation and computing and can be used in automated systems for monitoring parameters of electronic equipment.

A device for software control of computing systems is known that does not have a diversified application area, since its action is based on the invancy of the control mode, otherwise it is necessary to change the structure of the device l.

Closest to the proposed invention, the technical solution is a device for software control of equipment control systems. containing a pulse generator connected to one input of the element I, a command counter, a decoder and a PSI MINT 2 unit.

However, this device does not allow to change the control mode, since it only has different time intervals between microcommands following each other from the beginning to the end of the program, and working out a selected group of microcommands from a given program is possible only when the structure of the device is changed. In addition, the device does not allow controlling the control systems of various radio-electronic devices, since the control program also changes the entire structure of the device, which significantly reduces equipment utilization.

The purpose of the invention is to expand the scope of application of the device by increasing the number of control modes and simplifying the restructuring of the device when the control program is changed.

The goal is achieved by the fact that in a device for software control of equipment control systems, containing a pulse generator connected to one input

0 And elements, command counter, descrambler and memory block. A delay block connected by the input to the output of the AND element and one device output are entered, a comparator, KoiviMyTaTOp

5 commands connected by the outputs to the first inputs of the comparator and the command counter, and the synchronization unit, the outputs of which are connected to another input of the AND element and one input of the decoder, and the inputs to one input

I will give a device connected by other inputs to the command switch inputs, a comparator output, an input and one output of a delay block connected by an input to an output of an AND element and another output to a second input of a command counter, the output of which is connected to another decoder input and a second comparator input The other outputs of the device are connected to the outputs of the memory block, the element I, and the decoder connected by the output to the input of the memory block.

The drawing shows the functional diagram of the device.

The device contains a generator 1 pulse. (clock), element 2 AND (key), block 3 delays, counter 4 commands, decoder 5, block 6 of memory, switch 7 of commands (information input block), comparator 8 codes, block 9 of synchronization. The switch 10 shown in the drawing, the unit of measurement and control 11 and the unit 12 of primary processing of information relate to the device-controlled equipment control system, the object 13 of control. The input buses 14-17 of the communication bus device of the system 18 and 19 with the control object, the output bus 20-24 of the device (system inputs).

The device works as follows.

In monitoring the radio-electronic object 13, unified parameters are measured and monitored, which are directly measured (e.g., constant voltage) and parameters that require prior conversion, i.e., reduced to a uniform type (e.g., receiver sensitivity, bandwidth, etc.). converted to the corresponding constant value, voltage).

So, y, the device memory block controls, depending on a given program, the automatic switch 10 when monitoring a unified parameter (constant voltage measurement) or block 12 preprocessing information when monitoring a parameter requiring preliminary conversion to a uniform type, for example constant voltage. to life. If for a given microcommand according to the program it is necessary to measure a unified parameter, then the output of the control object 13 is switched to the input of the measurement and control unit 11 via the switch 10. If for this microcommand according to the program it is necessary to measure the parameter that requires preliminary conversion, the memory 6 issues a command to convert it para.ztra block 12 primary processing of information. Block 12 has forward 18 and reverse 19 links to object / 13 control.

which are used to control the monitoring object 13 and obtain the necessary information from it in the process of converting the measured parameter to a unified form. c. After finishing the operation of block 12 of primary information processing from its output, the input of block 11 of measurement and control is informed of the value of the monitored parameter.

o Control of the automatic control system through the memory block unifies the control process. The change of the electronic control object 13 requires only a change of the control program incorporated in the memory block 6. The structural construction of the control unit allows the control modes of the automatic control system to be varied. Device

0 control ensures the execution of one arbitrary microcommand of the control program, the sequential execution of the entire set of microcommands under the control program, and the sequential execution of the selected group of microcommands under the control program.

When executing one arbitrary microcommand with a special command, the synchronization block 9 and the counter 4

0 commands are reset. At the same time, the blocks of the automatic control system are reset to the initial state via the circuit 20. An arbitrary microinstruction is recorded in the instruction counter 4 via circuit 14 in the dial field of the information input unit 7. When applying the trigger signal on the chain 17, the synchronization unit 9 generates

Q permitting potential arriving at the second input of the decoder 5, allowing the conversion of the command code coming from the output of the counter 4. At the output of the decoder 5, a signal appears that arrives in parallel along

5, circuit 21 and the input of the automatic control system, where the microcommand number is recorded, and to the input of the memory block b. The incoming signal samples the corresponding

0 memory elements of memory block b. From its first output, the information on the value of the tolerance field along the chain 22 enters the input of the automatic control system. From the outputs of block 6

5 memory control signals are received respectively via chains 23 to 24 to the inputs of the automatic control system,

After completion of the measurement, the automatic control system generates a pulse, which through the circuit 16 is fed to the input of the synchronization unit 9 and sets the initial state of the unit 9 and through the circuit 20 - the automatic control system units. If it is necessary to re-execute this micro-command, the triggering signal is supplied to the synchronization unit 9 via the circuit 17, and the operation algorithm is repeated. When sequentially performing the entire set of microcommands, the control is carried out as follows. By a special command, the synchronization unit 9, the counter of 4 instructions and, through the circuit 20, the blocks of the automatic monitoring system are reset. When an ea-g signal is applied through circuit 17, the synchronization unit opens key 2, allowing the pulse from generator 1 clock pulses to pass through key 2 in parallel to the first inputs of synchronization unit 9, block.3 delays and circuit 24 to units of the automatic control system . The incoming impulse sets the synchronization unit E and the automatic system control units to their initial state. The synchronization unit 9 closes key 2 and stops supplying the clock pulses from generator 1. The delay block 3 produces two successive pulses, with the first pulse separated in time from the triggering pulse and from the second pulse by a predetermined value. The first pulse is recorded in the counter 4, the second pulse acts on the synchronization unit 9. The synchronization unit 9 generates the resolving potential, which arrives at the second input of the decoder 5, allowing the conversion of the command code from the output of the counter 4. At the output of the decoder 5, a signal appears that arrives in parallel along the circuit 25 to the input of the automatic control system, where it registers: 2 the number of the microcommand and the input of the P1mTi block, which controls the automatic control system according to a given program. After the measurement is completed, the automatic control system generates a pulse, which is fed through the circuit 20 to the fourth input of the synchronization unit 9. The synchronization unit 9 opens the key 2. The micro-command is changed and the control algorithm is repeated. After the last execution of the g / tg command from the entire set of microcommands, the control unit is reset. When the selected group of microinstructions are executed in sequence, the control is carried out in the following way. By a special command, the synchronization unit 9, the counter 4, and along the chain 24, the blocks of the automatic control system are reset. The first microcommand from the selected group is recorded in counter 4 through circuit 18 in the dial pad of information input unit 7. The last microcommand from the selected group is installed on the dial field in the information input block through circuit 19. When the trigger signal is applied through circuit 21, the synchronization unit 9 generates a resolving potential that arrives at the second input of the decoder 5, allowing the conversion of the counter 4 output. teams. At the output of the decoder 5, a control potential appears in parallel to the input of the automatic control system, where the micro-command number is recorded, and to the input of the memory block 6, which controls the automatic control system according to a given program. After completion of the measurement, the automatic control system generates a pulse, which through the circuit 16 is fed to the input of the synchronization unit 9. The synchronization unit 9 opens the key 2, allowing the pulse from the clock pulse generator 1 to pass through the key in parallel to the first inputs of the synchronization unit 9, the delay unit 3 and, through circuit 20, on-byki of the automatic control system, to the initial state. Block 9 synchronization closes the key 2 and stops the flow of the clock; impulses from the generator 1. Unit 3 produces two consecutive pulses underwater, with the first impulse being separated from the triggering impulse and the second impulse by a predetermined amount. The first pulse is recorded in the command counter 4, the second pulse acts on the synchronization unit 9. The synchronization unit 9 generates a permit potential and the control algorithm is repeated. When the last of the selected micro-command group is executed, the code of this micro-command from the output of the counter of 4 commands goes in parallel to the input of the decoder 5 and to the first input of the comparator 8 codes. Simultaneously with the execution of the last of the selected microcommand groups, the control algorithm compares the codes with the comparator 8 codes arriving at the first input from the output of the counter of 4 commands, and to the second input from the output of the information input unit 7. When the code of the executed microcommand coincides with the code of the command set on the dial field of the information input block 7, a 8 code comparator is triggered, and the inhibitory potential arrives from the output of the 8 code comparator. Therefore, at the end of the measurement on the last of the selected micro-command group, the micro-command is not changed. And the impulse produced by the automatic control system after the end of the measurement.
