Description

The invention relates to telemechanics and can be used, in particular, to control automated radio transmitters.

The purpose of the invention is to increase the reliability of the device.

The drawing shows a structural electrical circuit of the device.

The device contains the first commutator 1, the remote control unit 2, the remote signaling unit 3, the second switch 4, the controlled transmitters 5, the radiation monitoring units 6, the comparison units 7, the signal generation units 8, 5 prohibition keys, the keys 9. The device is connected information channels 10, channel 11 telecontrol (TU) and channel 12 tele-alarm (TC).

Switch 1 provides the connection of information channels 10 to the modulation inputs of transmitters 5 th corresponding blocks 7 comparison,

The telecontrol unit 2 provides for receiving and deciphering command-control-25 of the transmitter 5 and switches 1 and 4,

The television signaling unit 3 provides for the transmission of 12 code combinations to the channel, corresponding to the data 30 on the states of monitored parameters and controls.

The switch 4 provides the connection of the outputs (inputs) of the telecontrol unit 2 (3 tele-alarm systems) to the corresponding transmitters 5.

Blocks 8 provide for the formation of a prohibition signal that arrives at the control input of the corresponding key 9, which closes this key and, of course, disconnects the outputs of the comparison units 7 from the vehicle unit 3 in all modes except AT. The technical implementation of blocks 8 is determined by the principle of issuing television signals from the transmitter 45.

In cases where information about sos. The controls (parameters) are transmitted as signals along separate circuits (i.e., according to the principle 59 drive-command), block 8 can be implemented as a trigger, to one of the inputs of which the AT mode television signal line is connected, and the other is "High voltage off-55". ^!

If the transmitter status information is issued in the form of code com2

Binations, then the specified trigger inputs are connected to the remote signaling circuits, respectively, via AT mode and High voltage off tele-signal decoders. Decoders provide the conversion of code combinations of data of television signals into signals of a logical unit.

Thus, when the transmitter is turned on in the AT mode with a television signal from its output, the trigger is transferred to one state and the key 9 is opened from its first output. When changing the transmitter's operating mode, the trigger will be "transferred" to the zero state by the "High voltage off" signal that precedes any remote control session and the output of block 8 will generate a prohibition signal, which will close the key 9,

Device - works as follows.

In the initial state, the transmitters 5 are turned off, signaling about this from them through the second switch 4, block 3 is fed to the channel 12 of the vehicle and then to the control center.

When the "Decentralized control" command is received and the unit 2 decrypts it, a signal is issued to the first switchboard that connects the first (modulation) inputs of the transmitters 5 to the corresponding channels 10.

When the “Control) transmitter” command is received and block 2 decrypts it, a signal is issued to the second switch .4, which connects the second input and the second output of the transmitter 5 ~ 3 to blocks 2 and 3, respectively. When receiving control commands (setting mode, frequency, high and

etc.) they go through block 2 and switch 4 directly to the transmitter 5-h.

The television alarm about the status of the transmitter 5 ~ 3 is given from its output through the switch 4 and block 3 to the channel 12 of the vehicle. If the transmitter is included in the AT mode, the television signal "AT Mode", acting on block 8, generates a signal at its output that opens the key 9 ~ 3.

The signals from the sensor test test connected to the information channel 10 at the control station, are fed to the input of the transmitter

5 ~ s and block 7-3 comparison. The radiation control unit 6-3 estimates the level of power emitted by the transmitter 5-3 on the air, and, if it corresponds to the preset one, sends to the block 3 a telegram of the “Emission of a given power”, which is transmitted via channel 12 to the dispatch center. Simultaneously from block 6-3, the signals, in time with the radiation signals, arrive at the input of the block 10 7 ~ 3, where they are compared with the signals coming through the information channel 10. With the same polarity of the signals, the block 7 ~ 3 generates the "Radiation is correct" tele-signals, which It is transmitted through the public key 9-d and block 3 to the control room, where the sensor of the control test is disconnected and the terminal equipment is connected.

If the polarity of the signals is different, 20 then block 7 ~ 3 generates the signal "Reverse polarity". On this signal, either the polarity of the signals at the control point is changed, the libre is connected to another transmitter. 25

If it is necessary to change the transmitter's tuning frequency or operating mode, transmit the command “Control by the 3rd transmitter”, turn on the high voltage, and then send the necessary control commands.

At the same time, after turning off the transmitter 5 ~ with the TV signal "High off", arriving at block 8-3, the signal of pret ₅ pret is formed at its output, closing the key 9 ~ 3. If after turning on the transmitter it will work in any mode other than AT,

the key 9-3 will remain closed and the television signaling about polarity violation in block 3 is not issued. If the operating mode remains the same (AT mode), then this signal coming from the second transmitter output will generate a signal at the output of block 8-3, which will open the key 9-3.

After finishing the work and turning off the transmitter 5 ~ s, the device returns to its original state.

When the "Centralized control" command arrives and it is decrypted by block 2, a signal is sent to the first switch 1, which provides connection to the first information channel of the first 10 inputs of all transmitters 5. Each transmitter is controlled in the same way as in the "decentralized control" mode. After setting the high-voltage switch-on, a test test sensor is connected to channel 10. The operation of blocks 6, 7, 8 and 9 is similar to that described for a single transmitter. Connecting the terminal equipment to the information channel 10 is made after receiving the television signal "Radiation is correct" from all transmitters. If any of the transmitters 5 emits reverse manipulation, then if there is a backup (for example, when used for transmission to transmitters of η available, and k4p), the faulty transmitter is turned off, and the backup one is turned on, If there is no backup transmitter, then the faulty transmitter turn off.
