Description

one

The invention relates to a thalem hansche and can be used in information transmission devices used in the oil, gas and other industries.

It is known device auth. St. 327620 for transmitting discrete information in a start-stop manner, comprising a clock pulse generator, a keyboard with contacts and memory cells, encoding a keyboard interlock node, a start-stop distributor, and a trigger. The outputs of the keypad memory cells through the OR circuit are input to the first cell of the typesetting node, the remaining cells of which are connected to the output of the coding node, and the reading inputs of the typesetting cells are connected to the outputs of the start-stop distributor, the number of bits of which is one bit greater

the number of information elements in the start-stop cycle. At the same time, the outputs of the cells of the dial-up node are connected via the second cxewiy OR to the counting7 input of the trigger, and the outputs of the keyboard memory cells are connected to the input of the coding node directly.

The purpose of the invention is to eliminate phase distortions in the operation of the start-stop register when shifting clock pulses.

This is achieved by the fact that the output of the first OR circuit is connected to the input of the trigger pulse former.

The drawing shows a functional diagram of the device.

The device consists of a distributor 1 interrogation connected to (2 memories, control unit 3, encoder 4, first circuit OR 5, driver 6 starting pulse, register 7, generator 8 clock pulses, neck circuit AND 9, second switch OR 10, circuit NOT II, modulator 12, signal frequency generator 13, and amplifier 14, which is connected by a communication channel through demodulator 15 to the teletype machine 16 of the control room 16. The survey distributor begins polling memory blocks 2 at the command of control unit 3, which starts sporadically or cyclically in head Characteristics from the data collection system.The memory blocks 2. register technology parameters in decimal or binary code. Through the I poll allocator, the sequential memory blocks are connected to the encoder 4, which converts the decimal or binary code into a parallel five-element second international code. For any combination of signals G and O at the output of the encoder 4, the first OR 5 circuit supplies a signal to the driver 6 of the trigger pulse. The triggering impulse from the forlier 6 starts the register 7 into operation. Register 7 begins to shift the pulses from the generator 8 clock pulses, which leads to the appearance of the signal 7 of signal I at each of the six outputs of register 7 at the output of the AND 9 and second OR 10 circuits, the combination of O and I of the second international code appears in sequence. In this case, with the first circuit AND, the signal I is always supplied, which corresponds to the supply of the starting signal to the communication channel for receiver synchronization. Thus, a parallel second international code is converted into a serial one. 4 Depending on the input signal from the output of the HE II circuit to the output of the modulator 12, a signal frequency is supplied from the generator 13 to the input of the amplifier 14. With a signal I at the input of the HE II circuit, a pulse with a duration, is sent to the communication channel. filled with signal frequency. Moreover, the duration T, is determined by the frequency of the generator of clock pulses. All signals from the output of the encoder 4 are successively transmitted through AND 9 circuits. Terminally transmitting the signal from the last AND 9 circuit is equivalent to applying a stop signal, which is fixed at the control room. Register 7 operates in the start-stop mode and is only triggered by a pulse from the trigger pulse generator, which is triggered every time when the next bit of memory block 2 is polled. This sequentially polls all the memory blocks, converts the codes, and transfers information to the control room. At the control room, the demodulator 15 starts the teletype 16 with the first pulse after the response of the imaging unit 6 during the transmission of each bit of information. The proposed device is part of the remote control device for distributed objects, the SUBJECT OF THE INVENTION A device for transmitting remote control information on the author. St. No. 327620, characterized in that, in order to exclude phase distortions in the operation of the start-stop register when shifting clock pulses, the output of the first OR circuit is connected to the input of the starting pulse generator.
