Abstract

This invention relates to the field of telemechanics. The purpose of the invention is to increase informational flexibility by separating the input of information and its transmission. After the control signal has been input to the device, the incoming information is converted into a serial code and written bit by bit into the drive. After the end of the recording, the pore begins to transmit the information recorded in the storage device through the communication channel to the receiving side. At the receiving side, the received signal bit is recorded into its drive and transmitted via the reverse link to the transmitted side, on which it is compared with the previously transmitted bit. If they match, the comparison unit gives the command to transmit the next bit recorded in the n & kopitel etc. In case of distortion of the transmitted signal on the transmitting side, a reset signal is generated, which erases the previously transmitted information from the accumulator on the receiving side. After receiving the reset response signal, the transmitting side resumes the transmission of information from the start, starting from the first digit. 2 Il.

Description

The invention relates to telemechanics and can be used to transmit information from a moving object to a computer.

The purpose of the invention is to increase informational flexibility by separating the input of information and its transmission.

Figure 1 shows the functional diagram of the transmitting part of the device; Fig, 2 is a functional diagram of the receiving part of the device.

The device contains on the transmitting side an input block 1, a counter 2, a multiplexer 3, a counter 4 ,, multiplexer 5, a shaper 6 of address and write signals, a drive 7, a key 8, a clock generator 9, a comparison block 10, a receiving block 11, a block 12 transmission, address setting device 13 and trigger 14, and at the receiving side - receiving unit 15, comparison unit 16, shaper 17 of the address and recording signals, storage device 18, clock generator 19, switch 20, transfer unit 21, counters 22 and 23, switches 24 and 25 and 26 input.

The transmitting and receiving sides are connected by communication channel 27.

The receiving unit 11 consists of a filter unit 28 and a pulse generator unit 29.

Transmission unit 12 consists of generator units 30 and 31, switches 32 and 33, and amplifier 34.

The receiving unit 15 consists of filter units 35 and 36, a key 37, blocks 38 and 39 of pulse formers.

The transmission unit 21 consists of a switch 40, a generator unit 41 and an amplifier 42.

The device works as follows.

In the absence of information and a control signal at the first inputs of the device, counters 2 and 4, multiplexers 3 and 5, trigger 14 and shaper 6 are in the initial state, key 8 is closed and there is no signal at the output of the control unit 12. From the receiving side of the response signal to the input of the receiving unit 11 not post10

At the receiving side, in the absence of transmission, the driver outputs are set to zero, the keys 37 and 20 are closed, the receipt signal to the input of the communication channel 27 is not received, the counters 22 and 23, the switches 24 and 25 are in the initial state and the outputs of the output information block 26 are not received vuit.

After entering the control signal into block 1, information is recorded into the drive 7.

The incoming information is divided into bytes with the help of counter 2 and multiplexer 3, and then from the output of multiplexer 5, the bitwise information is fed to accumulator 7. Former 6 generates control signals to perform the playback and playback. The key 8 receives, stores the signal of an anchoring and remains open until the damping pulse arrives at the third input, which 25 also enters the trigger 1 input. From this moment on, the input of information stops and the transmission begins. The transmission to the communication channel 27 of the address is carried out without direct cavitating by switching tones.

frequencies from the generator unit 31, with the power of the reception unit 15, the signal address is received and input to the comparison unit 16.

If the code with the codes of the receiver of information coincides, open the key 37.

After a specified time after the transmission of the address, the imaging unit 6 sends a control signal for transmitting a bit with zero addresses, i.e. The first bit of information is transmitted from the output of the communication channel 27 through the public key 37 to the input of the generator 17, the input of the accumulator 18 and the input of the transmission unit 21. The imaging unit 17 supplies the drive 18 with the write bits of the incoming bit to the accumulator 18. The received signal via the transmission unit 21, the communication channel 27 and the reception unit 11 is fed to the second input of the comparison unit 10, where it is compared with the transmitted signal. If they match

is drinking In view of the fact that both inputs of the 5S block, the block 10 supplies the control signal

the comparisons are zeroed, the output signal from the block is absent and the state of the driver 6 does not change.

at the end of the transmission of this bit and the reading of information from the next address of drive 7 and others.

At the receiving side, when there is no transmission, the driver 17 outputs are cleared, the keys 37 and 20 are closed, the receipt signal to the channel 27 of the communication is not received, the counters 22 and 23, the switches 24 and 25 are in the initial state and at the outputs of the information output block 26 missing .

After entering the control signal into block 1, information is recorded into the drive 7.

The incoming information is divided into bytes with the help of counter 2 and multiplexer 3, and then from the output of multiplexer 5 the information is fed bit-by-bit into accumulator 7. Shaper 6 generates control signals for cell dresser and the algorithm of operation in recording-reproduction modes. The key 8 receives, stores the signal of the anchoring and remains open until the damping pulse arrives at the third input, which also goes to the input of the trigger 14. From this moment the information entry stops and the transmission begins. The transfer to the communication channel 27 of the address is carried out without continuous cavitating by switching tones.

frequencies from generator block 31, with the help of reception block 15, an address signal is received and fed to the input of comparison block 16.

If the address code coincides with the information receiver codes, the key 37 is opened.

After a predetermined time after the end of the address transmission, the driver 6 sends a control signal to transmit a bit with zero addresses, i.e. the first bit of information is transmitted from the output of the communication channel 27 through the public key 37 to the input of the imaging unit 17, the input of the accumulator 18 and the input of the transmission unit 21. The imaging unit 17 supplies the drive 18 with the recording of the incoming bit to the drive 18. The received signal via the transmission unit 21, the communication channel 27 and the reception unit 11 is fed to the second input of the comparison unit 10, where it is compared with the transmitted signal. If they match

block 10 delivers a control signal

at the end of the transmission of this bit and the reading of information from the next address of drive 7 and others.

in the case when the transmitted signal is distorted, i.e. If the transmitted bit does not match the received signal, block 10 will generate a reset signal that will reset shaper 6 to the zero address and simultaneously through drive 7 it will be fed to the input of switch 32, which will connect the generator of resetting generator block 30 to the input of amplifier 34. Through communication channel 27 and receiving unit 15, a reset signal will be fed to the input of the driver 17, to the input of the accumulator 18 and to the input of the transmission unit. As a result, the driver 17 will be reset to zero address, and through the key 20, the counters 22 and 23 will also be reset to zero. Through the switch 40, the reset frequency generator unit 41 will be connected to the input of the amplifier 42, and a reset frequency signal will be sent to the communication channel 27. This signal will be received by reception unit 15 and fed to the second input of comparison unit 10. As there will be a reset signal at the other input of the comparator unit 10, the transmission of the reset signal from the transmitting side will be prohibited and the transmission of information stored in the accumulator 7 will be resumed, starting from zero address.
