Description

The invention relates to automation, in particular to control systems for radio transmitters,

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

The drawing shows a structural diagram of a device.

The device comprises a first distributor 1, an encoder 2 position numbers, an encoder 3 operations, elements And 4 of the first group, a second distributor 5, a first trigger 6, a command transmission control unit 7, consisting of control keys 8 and a third distributor 9, the first element OR 10 , second trigger 11. And element 12, second OR element 13, third trigger 14, And elements of the second group 15, key group 16, key 17, trigger 18, counter 19, AND-NOT element 20 and inverter 21.

The transmitting distributor 1 forms a sequence of control pulses for the operation of the entire device, including for the encoders 2 and 3. The encoder 3 forms the part of the code combination that determines the position of the selected machine. Elements And 4 allow encryption of only those circuits in which mismatch signals occur between the dialed command and the state of the tele-alarm elements; they control the operation of trigger 11 through element OR 10. The distributor 5 is controlled by distributor 5 (acyclic), for which trigger 6 is generated by control pulses. Acyclic distributor 5 alternately connects to encrypt the circuit, which are prepared by multi-position keys 8.

With the beginning of a new cycle of advancement of the transmitting distributor 1, the “Start” pulse through the And 12 element triggers the trigger 6, which switches the distributor 5 to the next position. At the same time, the Start pulse from the distributor triggers the trigger 11, which generates the pulses of advancement of the distributor 9 (acyclic), from the outputs of this distributor the signals go to the inputs of the elements And 4, the other inputs of which receive signals from the outputs of the encoder 3 through the corresponding keys 8.

Since several positions can be included in one operation, the signals from the output of the encoder 3 operations through closed keys 8 can simultaneously arrive at the inputs of several elements AND

4.

The distributor 9 moves from one position to another, while from its outputs to the inputs of the elements 14 4 are fed alternately signals. When installing the distributor 9 in a position in which at the other input of one of the elements 14 4 there is a signal from the output of one of the keys 8, a signal is generated at the output of the specified element And 4. The latter enters through the element OR 10 to the input of the trigger 11, stopping it. Further promotion of the distributor 9 is prohibited. From the corresponding output of the distributor 9, the signal is fed to the control input of the encoder 2, allowing encryption of the positional part of the code combination. In this case, the stop signal is received from the output of the encoder 2 to the input of the trigger 6, prohibiting further movement of the distributor 5.

With the beginning of a new cycle of promotion of the distributor 1, the Start pulse from its output starts the trigger 11, which generates clock pulses to advance the distributor 9 to the next position. If there is a signal from the output of one of the keys 8 at the input of the corresponding element And 4, the distributor 9 stops and the positional part of the code combination is encrypted.

The stopping process of the distributor 9 is similar to the above.

In the next cycle of promotion of the distributor 1, the Start pulse from its output starts the trigger 11, which generates clock pulses for further promotion of the distributor 9.

If there are signals from the outputs of the closed keys 8 at the inputs of other elements 14 4, the operation of the device occurs similarly to that described above.

In the absence of signals at the inputs of the And 4 elements, the distributor 9 reaches its initial position, and the signal from its output enters through the OR 10 element to stop the trigger 11 and simultaneously to the input of the And 12 element.

With the beginning of a new cycle of promotion of the distributor 1, the Start pulse from its output enters through the And 12 element to the input of the trigger 6, which switches the distributor 5 to the next position. At the same time, the Start pulse ”from the output of the distributor 1 starts the trigger 11, which generates clock pulses to advance the distributor 9.

In the presence of signals from the outputs of the closed keys 8 at the inputs of the elements And 4 the operation of the device is similar. Upon receipt of confirmations about the execution of commands by the transmitter, the mismatch between the dialed commands and the telealarm signals disappears from the input of AND 4 elements and the encryption chains are opened. When the last encryption circuit is opened, the operation of the device automatically stops. When using a device for transmitting tele-signaling from radio transmitters, the multi-position Sensors for signaling the status of controlled objects are used as keys 8. In this case, enable signals are constantly sent to the telealarm inputs.

When an alarm occurs at the output of one of the signal elements AND 4, the signal goes to the input of the OR element 13 and then through the AND-NOT element 20 and the inverter 21 to the input of the trigger 14. The trigger 14 is triggered and gives a permission signal for one of the inputs of the corresponding element And 15 , the second input of which receives a signal from the output of the corresponding element And 4. From the output of the element And 15 receives a signal to the control input of the key 16. The key 16 is opened, connects for encryption corresponding to the transmitter address (by the number of the signal element And 4) . Simultaneously with the formation of the address command from trigger 14, a signal is sent to key 17, which opens and closes the corresponding circuit of another operation • to form the Dispatch request command. If an alarm occurs on one of the AND 4 elements, the signal through the OR 10 element is sent to the trigger 11, which generates clock pulses to advance the distributor 9, stops it at the corresponding positions of the closed keys 16 and 17, and the transmitter Address and Dispatch request commands are encrypted.

The signal from the output of the electronic key 17. arrives at the input of trigger 18. which triggers and sends a signal to the enable input of counter 19. During the dispatch request, the status of the groups (from the first to the last) is interrogated twice, during the polling of the last group of 10 dispenser 1, an impulse arrives at the counting input of counter 19 . When the second pulse arrives, the signal from the output of the counter 19 trigger 18.

During a dispatch request, the signal from the output of the trigger 18 locks the key collected on the NAND 20 element and the inverter 21 so that the alarms from the OR 13 element do not pass to the trigger 14. This eliminates the looping of the device.
