Description

The invention relates to telemechanics, in particular, to code pulse systems of telecontrol and remote signaling, designed to control automated radio transmitters.

The purpose of the invention is to increase the reliability of the device by reducing the number of channel control units.

Figure 1 shows the structural electrical circuit of the device.

The device contains the first mutator 1, remote control unit 2 (TU), remote signaling unit 3 (TS), second switch 4, automated radio transmitters 5, third switch 6, control unit 7, driver 8 commands. Main and backup information channels 9 (by the number of transmitters), remote control channel 10 and remote signaling channel 11 are connected to the device.

Figure 1 shows the structural electrical circuits of one of the possible variants of the technical realization of the first switch 1, the connection unit 6 and the driver 8 commands.

Switch 1 contains P switching nodes, each of which consists of a control trigger 12, a first 13 and a second 14 keys. The inputs of the keys 13 and 14 are the inputs of the switch 1 and are connected respectively to the main and backup information channels. The keys 13 and 14 are opened with signals from the outputs of the trigger 12, which is controlled by commands from block 2 Enable main channel - Enable backup channel. At the same time, the signals from the trigger outputs are sent to the command generator 8, signaling which of the channels is turned on - main or backup.

The third switch 6 contains a generator of 15 clock pulses, the period of which corresponds to the time of analyzing the quality of the channel by the control unit 7, the ring shift register 16 and the elements OR 17 The pulses from the generator 15 arriving at the clock input of the register 16 provide a consistent appearance of the signal at its outputs which are connected to the inputs of the corresponding elements OR 17. This provides

sequential connection of the control unit 7 to the manipulation lines of the transmitters 5 for the time required for the dp channel quality analysis. Single

temporarily from the outputs of register 16 to the driver of 8 commands, signals are output corresponding to the numbers of the transmitters, to the inputs of which the block 7 of the controller is connected at the given moment

roll

The shaper 8 commands contains n the first 18 and second 19 elements OR. In the shaper 8 commands based on the signals connected to the main

channel or connected backup

channel, outputted from the first switch 1, of signals characterizing the number of the transmitter, outputted from the outputs of the register 16 of the third

mutator 6, and the signal. The channel is faulty, outputted from control unit 7; signals are generated; at the output of the first elements OR 18 - The main control channel of the jth transition

sensor is faulty, and at the output of the second elements OR 19 - the Backup control channel of the j-th transmitter is faulty ..

The device works as follows.

In the initial state, the main information channels are connected via the first switch 1 to the manipulation inputs of the transmitters 5. The control text is transmitted from the control room along the main information channels 9. The third switch 6 provides alternate connection of the control unit 7 to the first outputs of the first switch 1. If the quality of any main channel, for example j-ro, is worse than a given rate, from the control unit 7, the Bad channel signal comes from the control driver 8, and from the driver 8 commands - the signal corresponding to the number of the transmitter to which the block 7 control is currently connected. In the command generator 8, a signal is generated. The main control channel of the transmitter is faulty, which, enrolling and the TC unit 3, is encrypted there in a codeword and transmitted over the vehicle channel 11 to the control room. At the control station, after receiving the vehicle, they form a command Connect a backup channel to the transmitter, which is received by block 2 TU via channel 10 TUU

decrypted and issued at first. utator 1 where executed. From the first switching unit 1, the driver of command 8 begins to emit a signal about the connection of a reserve channel to the j-th transmitter.

To control the 5-i transmitter, a command is sent from the control tower to control the i-th transmitter, which is received by the unit

2TU. From it, a signal is output to switch 4, which ensures the connection of the control circuit of the i-th transmitter

to the corresponding circuit of the third switch 6 TU, and the signaling circuit to the corresponding circuit of the unit

3 tv alarm. When the control unit receives 2 TU control commands (frequency tuning, mode setting, high switching, etc.), they from the TU unit 2 arrive at the transmitter 5-i. ITC about their execution through the switch 4 and the TAC unit 3 via the channel 1) TS on the control room. at the control room, getting

С about switching on the transmitter 5-i, disconnecting the test control sensor from the i-th main channel and connecting the terminal equipment, after which they begin exchanging information with the sponsor.

The information from the i-th main information channel 9 goes through the first switch 1 to the manipulative input of the transmitter 5 i, and at the instants of time determined by the cyclical nature of the control, to the control unit 7, where the channel quality is assessed.

If during the operation of the i-th transmitter by the control unit 7 it is determined that the quality of the main i-ro information channel has become worse than normal, then in the shaper 8 commands (similarly to the one specified for the j-ro channel), a command is generated. The i-primary information channel is faulty. which is encrypted by TS block 3 and transmitted over the P channel to the control station. At the control room, the command Connect i is formed and the transmitter to the backup channel, which enters the TU 2, is decrypted and executed by the first switch 1, from which output to the command generator 8 a signal is received that a backup is connected to the i-th transmitter

channel. If the next cycle of monitoring the manipulation line of the i-th transmitter turns out that the quality of the backup i-ro channel is also worse than the norm, the signal is received from the control unit 7 to the driver 8. The channel is bad. Shaper 8

commands based on signals from the third switch 6, the control unit 7 and the first switch 1, similarly to the indicated type, generates a signal. The backup information channel is faulty, which is encrypted in the vehicle block 3 and transmitted through the P TC channel. When the i-ro main and backup channels receive the i-and the transmitter at the control center of the vehicle, the i-transmitter is turned off and if there is a backup transmitter 5 it is used to transmit information, and the i-th information channels are regulated. Switching on the transmitter is performed by sending a command from the control room of the i-th transmitter, which enters unit 2 and connects the control circuits and the vehicle through the second switch 4 to the units TU 2 and TC 3, respectively, and then sends the command to turn off the transmitter, which goes directly to I s transmitter
