Description

mode of information output on a magnetic contribution.

The proposed device in the first mode works as follows.

Sync pulses with a 1-second tracing period are received from synchronization unit 1 to generator 2 of telegraph code 4; sync pulses with a repetition period of 1 s come from the synchronization unit 1 to the electronic clock unit 3. From the electronic clock, the impulses with a new period of 1, 2 and 5 min go to the control unit 4, where the switch selects the sensor polling frequency.

The polling unit 5 together with the telegraph code generator 2 is a three-stage start-stop counter, which is in the initial state before the arrival of the selected pulse. With the arrival of the selected pulse, the first stage of the counter of the polling unit 5 switches from the initial state to the first state, as a result of which the generator 2 obtains the permission for counting pulses with a repetition period of 1 ms.

The generator 2 generates telegraphic packages, which are counted by the first and second counters of the polling unit 5.

The formation and counting of telegraph packages takes place until all three stages of the meter have been reset to their original state.

The polling unit 5 is designed to form a frame of information. At the beginning of the frame there is service information, which is: symbols indicating the beginning of the frame and the algorithm for receiving information; data on the current time (year, month, day, hour, and minute) and constant details (for example, workshop number, device number, number of connected subcommutators).

Then comes the primary information in packets of 31 characters, corresponding to information from 31 sensors.

The end of the frame is represented by the service information.

Selection unit 6 determines the number of service information characters at the beginning and at the end of a frame, depending on the operation of various computers and the number of polled subcommutator blocks 8, and their number is determined by a switch on selection unit 6, which makes it possible to rationally poll the connected equipment. In this case, the state of the first stage of the counter of the polling unit 5 determines the sensor number within the sub-switch unit 8, and the state of the second stage of the counter - the number of the polled sub-switch unit.

Selection block 6 consists of three toggle registers Rz, Rs, defining: register RI - overhead information in

frame start

register - the number of connected subcommutation blocks.

Register - the amount of service information at the end of the frame.

The second cascade of the polling unit counter 5 counts but the module L, where L is the number recorded in register 2, the first and the last state of this counter are allocated to the beginning formation and the overhead information, and the rest (N - 2) states are polled (/ V - 2) blocks of subcommutators 8.

The first stage of the block counter of onros 5 is programmed by the registers Ri and Rs, and in the initial state of the second stage of the counter, the capacity of the first stage of the counter is determined by the register Ri, and in the latter by the register Rs.

In the remaining states of the second counter cascade, the capacity of the first counter cascade

maximum.

The addresses of the interrogated sensors from the interface unit 7 are transmitted to the corresponding blocks of the subcommutators 8, which interrogate the sensors 9.

Information from the scanned sensors is fed to the interface block 7.

The frame information service including the current time information is received from the electronic clock unit 3 to the interface unit. Information about the necessary details of the frame enters the interface unit 7 from the memory unit 10.

The selected information from the interface unit is fed to the binary code converter 11 to the MTK-2 code. The parallel code MTK-2 is developed by the generator 2 of the telegraph code into a serial code and through the amplifier 12 is entered into the computer via the telegraph channel.

In the second mode of operation of the proposed device, the signal from the computer through the amplifier 12 is fed to the generator 2 and the comparison unit 13. The generator generates a symbol whose beginning coincides with the beginning of the signal

from the computer.

The content of the symbol to be generated is determined by the initial state of the polling block 5 and is equivalent to the expected polling trigger symbol from the computer.

In the comparison block 13, the generated symbol and the received signal are compared, and if they are identical, the comparison block generates a trigger pulse of the polling unit 5. Next, the device operates as in the first mode.

In the third mode, the proposed device operates as follows.

From the electronic clock unit 3, a start pulse with a repetition period of 1, 2 and 5 minutes goes to the control unit 4, in which the required polling interval is selected using a switch. The selected pulse alternately. Includes perforators 14. Sync pulses from the rotator through the control unit 4 are received

PA block survey 5.

Further, the device works in the same way as in the first mode, for 11 seconds: And m south, that the frame of information in the parallel code from the output of the converter 11 is transmitted through the control unit 4 to the perforators 14.

In the fourth mode, the proposed device operates in the same way as in the first mode, except that the frame of information from the generator 2 output of the telegraph code in the serial code through the control unit 4 is not recorded on the tape recorder.

In addition to the basic function of collecting neural information, the proposed device allows obtaining the following operational information, for example: the number of sensors that the operator is interested in (one of ten); the state of the sensor of interest at the current time; a summary of the state of all sensors for each state.

At the request of the operator, during the subsequent frame of information from the polling unit 5, the address of the equipment to be returned to the display unit 16.

The condition of the polled equipment comes from the interface unit 7.

Operational information in block 16 is displayed on a board and printed as a table.
