None of the exchange mode, line 9 — for transmitting the readiness signal for operation of transmitter 11 or information receiver 12, line 10 — for transmitting interrupt signals from the device blocks to the computer 1,

In addition, the device has (figo2) decoder 18, first element I 19, trigger 20, register 21, output 22 of the address indication computer, information output 23 of the computer, synchronous output 24 of the computer, synchronous input 25 of the computer, interrupt line 26 of the computer, encoder 27, demulti - plexer 28, register 29, multiplexer 30., element OR 31, timer 32.33, fourth 34, third 35 AND elements, decoder 36, first AND element 37, trigger 38, second And 39 element, encoder 40, decoder 41, the first element And 42, the first 43 and second 44 triggers, the second element And 45,

Computer 1, according to the control program, via the interface 2, establishes the necessary mode of information exchange (synchronous or asynchronous, enabling or disabling interrupt service, program polling) with meter 13 or other blocks 14, 15, 17,

The choice of mode is determined by the exchange of information, speed and other technical characteristics of each of the gauges and other controllable units of the device 14, 15, 17, and also the object

16 controls

The principle of operation of the transmitter unit i interface 11 and the group information receiver 12 is as follows.

The encoder of the transmitter 11 and each receiver 12 of the information of the group has a separate, not coincident

with others in the system, the address code “Structurally, the encoder can be executed in the form of switches or a removable device,

Computer 1 in accordance with the control program when transmitting information us-; It sets the corresponding address of the transmitter 11 of the group information, which is set once for the entire time of transmitting information at this address, receives confirmation of the receipt of the address and the readiness of the transmitter for operation. Then the computer 1 outputs, via the selected transmitter 11, the necessary Information to the device for which the information is intended (a generator of stimulating signals for setting the mode of the control object 16, a meter 13 for setting the required measurement mode, a switch 14 for connecting the corresponding output of the control object 16 and the meter 13 input, block 17 reference signals and the switch 14 when the device is self-controlled), similarly, but through the corresponding receivers 12, information in accordance with the control program of the computer 1 receives deformations of 13 meters from the digital outputs of the object 16 and other control devices controlled by the blocks 14, 15, 17 "

Organizing the looping modes of P13ogram, stopping the program at any given step, issuing messages about detected program errors with its subsequent scrapping, error messages about individual devices of the system in the process of self-control, monitoring the program by checksum and other operations are easily performed by software included in part of the computer software, and no explanation is required.

The conjugate block 2 operates as follows.

Computer 1 on information output 23 transmits the address code of block 2 for decoder 18 and the indication of address for output 22 to the second input of the first element And 19 If the address code at information output 23 coincides with the code for interface 2 and if there is an indication of address on the output 22, the trigger 20 permits the passage of the output clock of the computer 1 along the line from 1 input 24 through

the second element And 33 on the line synchronization input 25 of the computer,

The input line 25 is connected to the line of the group 8 of the common band 3, through which the transmitters 11 and the receivers 12 of the information group in the asynchronous exchange mode receive clock pulses from the blocks of the device operating in this mode.

The synchronizing pulse from the output of the element 33 confirms that the address code has been received by the interface 2 and provides a synchronous mode for transmitting information from the computer 1 to the register 21. Information from the computer 1 enters via the bus 23 and is written to the register 21 by the synchronizing pulses themselves from the second output of the second element II 33. The information in the register 21 is designed to enable or disable the interrupt signals of the computer 1, coming through the corresponding receivers 12 of information from the device blocks along the group of lines 10 of the common bus 3 through the third element 36 on line 26 of computer 1 interrupt; Register 21 also records information about synchronous or asynchronous exchange of computer information with device blocks

In synchronous exchange, the output synchronizing pulses of the computer 1 through line 24 through the fourth element And 34 are sent to line 25 and further to computer 1 if there is a enable signal from register 21 and an ready to exchange signal on line 9 of common bus 3, the Ready to Exchange signal sets the corresponding transmitter 11 or receiver 12 information.

During asynchronous exchange, the signal from the register 21 prohibits synchronous exchange and synchronizing pulses from the device blocks through the respective transmitters 11 or information receivers 12 and the common bus line 8 is fed to the synchronous input line 25 of the computer 1.

The information bus 23 of the computer 1 in the block 2 of the interface is connected to group 4 of the common bus 3, line 22, the indication of the address — to the line 6 of the common bus 3, line 24 of the synchronous output of the computer I - to the line 5 of the common bus

The information transmitter 11 operates as follows.

The computer 1, in accordance with the control program, transmits the address code to the decoder 18 via a group of lines 4 of the common bus 3, the indication of the address along the line b of the common bus 3 to the first input of the first element I 37 and the clock pulse through the line 5 to the second input of the first element I 37.

When the address code on a group of lines 4 coincides with the code of the encoder 27 from the output of the first element I 37, a synchronizing pulse arrives on the line of group 8, confirming receipt of the address code. Then the trigger 38 on line 9 of the group establishes the sign of readiness of the information transmitter 11, From the second output, the trigger signal 38 enables the operation of the dem

tillexer 28 and passing synchronously programmed by transmitting pulses from the device blocks in the asynchronous mode of exchange through the second element AND 39 to the line 8 of the common bus 3,

The amount of information transmitted, 25 i.e., the number of information words, is determined by the dimension of the control word of the device to which the information is transmitted. The demultiplex information from the computer 1 on the group of lines 4 of the common bus 3, the timer Time is selected from various considerations related to the capabilities of the meters 13, the control object 16 and other controllable units of the device with availability of readiness, speed and frequency. For example, if you use the meter 13 which does not have

a sor 28 specified by the program number of ready signals, but it is known

in information words, successively coming from computer 1 over a group of lines 4, using synchronizing pulses along a line of group 5, writes to register 29 o. As a result, at the output of register 29, an information word is formed with a given dimension (number of bits) which is supplied; Corresponding device block This unit also receives synchronized pulses from the group 5 line in the asynchronous exchange mode.

The receiver 12 of the information works as follows

The purpose and principle of operation of the decoder 41, the encoder 40, the first element 42 and the first trigger 43 of the reception 12 and the transmitter 11 of the information group are similar. The first trigger 43 gives the enable signal to the multiplexer 30 to receive information coming from the corresponding device block. . In addition, multiplexer 30 receives the resolution signal via the SHS 31 element from the second trigger 44 or from the timer 32. The second trigger 44 stores the device readiness signal (for example, the meter

P.

13 or object 16 control) and feeds it to the element OR 31, to the line 10 of the common bus 3 and through the unit 2 matched /

no further on the interrupt line of the computer 1, Timer 32 receives the enable signal from the first trigger 43,

The information coming from the system devices in the form of an information word of various dimensions, multiplexer 30 transmits over a group of lines 7 of the common bus 3 to the input of the computer 1 in the form of a corresponding number of consecutive information words with

information bus dimension - computer 1,

Timer 32 sets the time after which the reception of information is permitted. Time of the timer is pre-programmed by transmitting

Information from the computer 1 through the group of lines 4 of the common bus 3; The timer time is selected from various considerations related to the capabilities of the meters 13, the control object 16 and other controllable units of the availability signal, speed and heartbeat. For example, if a meter 13 is used which does not have

speed, reception of information from: the timer delays for an appropriate time after issuing the control word (measurement commands); In addition, timer 32 allows you to eliminate such a disadvantage of the known ones-i, like underwriting of the computer 1, which is possible without the signal whose parameter parameters are measured, since the meter 13 (for example, the frequency meter 43-54) in this case does not give a ready signal.

Receiving information from multiplexing 30 of the computer 1 can be performed at any time convenient for the monitoring program, as well as upon request, arriving as a readiness signal on the interrupt line of the computer 1,

n 55

Thus, the device provides the exchange of information with various devices in synchronous or asynchronous mode, with software polling or with a request for non-interrupt service, which allows the use of devices with different information exchange capabilities and ensures the flexibility of programming the CEA control process

To perform the device, various control computers can be used, for example, Electronics DZ-28, Electronics NTs-OZD, and others, as well as any measuring instruments with 1 WDF remote control (for example, frequency meter 43-54, voltmeter B7-23, voltage converter stroboscopic V9-5, pulse voltmeter V4-20, and others). As a switch in the system, switches can be used, for example, F-779/2, F-7078/03, F-7078/05, and others.

Using the proposed device in comparison with the known one will allow to obtain a technical and economic effect by simplifying the device and expanding its functionality, increasing reliability and speed, providing the flexibility of system rebuilding and building up other devices (for example, gauges, generators, and TD) with different possibilities. information exchange, with wider possibilities for programming the CEA control process,
