The invention relates to radio engineering and communication and can be used in control systems for objects of various purposes via communication channels, for example, telephone.

An object of the invention is to enable the reconfiguration of a device for receiving various control signals.

The structure of the device is shown in the drawing and contains a receiving and transmitting unit 1, made in the form of a subscriber telephone set, a filter 2, a pulse shaper 3, a single vibrator 4, a trigger 5, an element 6 AND, a delay unit 7, a counter 8, a switch 9, a register 10. a decoder 11, a switch 12, an output 13, an inverter 14, an AND element 15, a delay unit 16, a counter 17 and a communication line 18 with the circuit connections described above and in the formula.

The device operates as follows.

After power is turned on, trigger 5, counters 8.17, and register 10 are set to zero.

In order to receive signals at output 13, it is necessary in register 10 to accumulate information in various groups of bits (tatrades, triads) in several registers of signals in accordance with the output of the decoder connected via the pre-switched, well-defined contact of switch 12 to output 13. The signal to output 13, according to a predetermined condition, the control object may, for example, turn on or off. For example, it is necessary to turn off the remaining electric furnace for forgetfulness. For this, it is necessary by telephone to connect to the device 1 located in this room, and then dial the cipher of this object to act on it.

. The cipher signals are generated, for example, by tapping a finger on the handset on the transmitting side with a certain clock frequency, for example, 1 Hz. Tapping signals pass through the answering machine circuit 1, filter 2 and driver 3 (rectangular pulses) to counter 8 for counting them, and then through one-shot 4, trigger 5 and elements 14, b to determine the pause between a series of pulses (taps ) determining the end of the transmission cycle of one cipher symbol. The presence of a pulse at the output of the driver 3 maintains the trigger 5 in the O state, while the end of this pulse is a single-shot 4, which generates a pulse, for example, for a duration of 2 seconds. If the duration of the pause by the pulses of the shaper 3 is longer than the pulse duration of the one-shot 4, then at the end of the last element b fixes the coincidence of the signals of trigger 5 and inverter 14. When

In this case, the code of the cipher symbol from counter 8 through the switch 9 is rewritten into a group of bits of the register 10 corresponding to the address in counter 17. After this, the counter 8 is reset by element 7, and the counter 17 increases its contents by 1, preparing the switch 9 for recording information of the counter 8 to the next group of bits (triad, tetrad) of register 10. The series of a series of pulses with pauses between series is recorded in

5, register 10, the entire cipher, consisting of several characters. When the cipher is fixed on the transmitting side, an end signal is issued, for example, by returning the telephone handset to its place - the last one. In this case, the apparatus 1 generates a hang signal, along which the element 15 is reset, thereby ensuring the transmission of the code from; register 10 to the decoder 11, and after that the object control signal is transmitted

5 to output 13. After a time determined by block 16, register 10 and counter 17 are set to O.
