The invention relates to telemechanics and computing and can be used in multilevel automated control systems when building objects adapted to external conditions.

The purpose of the invention is to increase the reliability of the execution of a given command by issuing a signal for its execution adapted to external conditions.

The drawing shows a structural diagram of the proposed device.

 The proposed device contains a pulse generator 1, a group of registers 2, delay elements 3, first and second groups of decoders 4 and 5, element 6, time delay block 7, first 8, second 9 and third

The vital input, for example, register 2, is recorded as in a conventional shift register under the influence of generator pulses 1, which are fed to the synchronization inputs of registers 2. After the entire waveform has been recorded, the single pulse-marker is written to the zero bit of the register 2,. to the input element 3 delay and the gate input of the decoder 5 ,. If in the second group of register bits 2 a given command is written, then from the first output of the decoder 5 the signal is sent to the strobe decoder 4, which, correspondingly to the incoming code of the address of the sending point, gives the codogram to the corresponding

register 12, the first 13 and second 14 triggers, a group of elements AND 15, the first and second groups of elements OR 16 and 17, respectively, a group of information inputs 18 of the device, the signal input 19 of the device.

In the initial static state, registers 2 and 12 and triggers 13 and 14 are cleared, block 7 enters the selected T T-time, information inputs of registers 2 are connected to the outputs of communication channels, and the zero input of the OR element 9 to the output of the signal sensor on the occurrence of special conditions (fire, explosion, etc.) on the object, the register width 2 (series-parallel M-bit) corresponds to the size of the codograms received on the object in the form of an M-pozigacii serial binary code, the zero position of which takes impulse mar er, the following m bits of the first group takes the address of the sender, the item overheads, and the next, the second group of bits of text or ganimaet team of Li- bo warning signal. The number g of outputs of the decoder 5 is equal to the number of warning signals plus a unit corresponding to a given command, and when a command is received, the decoder 5 delivers a signal at the first output.

The device has two modes. In the first mode, the device operates as follows.

When a codogram arrives from any control point to this object, it from the output of the corresponding communication channel is fed to the informing element OR 16 is exposed to the information input of one of the bits of the register 12. The pulse from the first output of the decoder 5 goes through the OR element 8 to the input write register 12, which writes the unit to the corresponding jy j and to the unit input of the trigger 13, which is transferred to state 1 (from its output, the unit potential is set to the first input of the element 6 and also goes to od unit 7, which begins counting time T.

If, before the expiration of time T, the codogram with the command from any other control point did not arrive, then after the time T has expired, unit 7 outputs a signal which arrives at the setup inputs of the register 12 and trigger 13, and wrapped them. At the input of block 7, potential O is again applied, and block 7 returns to the initial state. The pulse from the output of element 3, the delay register 2, is zeroed and is ready to receive a new codogram.

If, before the expiration of time T, the codogram with a given command came from any other control point, then with a single state of trigger 13 and saving 1 in one of the bits of register 12 in the same way, 1 is recorded in another register bit 12. A node consisting of elements 10 ,, 15 and 17 ensures the appearance of 1 at the output of the element OR 10 (with trigger 14 post O) only in the case of recording 1

in two or more bits of register 12. Therefore, 1 from the output of the element OR 10

The OR element 16 is exposed to the information input of one of the bits of the register 12. An impulse from the first output of the decoder 5 through the OR element 8 passes to the input of the register 12, which records the unit to the corresponding bit j and the single input of the trigger 13, which is transferred to state 1 (from its output, a single potential is exposed to the first input of element 6 and also enters the input of block 7, which starts counting time T.

If, before the expiration of time T, the codogram with the command from any other control point did not arrive, then after the time T has expired, unit 7 outputs a signal which arrives at the setup inputs of the register 12 and trigger 13, and wrapped them. At the input of block 7, potential O is again applied, and block 7 returns to the initial state. The pulse from the output of element 3, the delay register 2, is zeroed and is ready to receive a new codogram.

If, before the expiration of time T, the codogram with a given command came from any other control point, then with a single state of trigger 13 and saving 1 in one of the bits of register 12 in the same way, 1 is recorded in another register bit 12. A node consisting of elements 10 ,, 15 and 17 ensures the appearance of 1 at the output of the element OR 10 (with trigger 14 post O) only in the case of recording 1

in two or more bits of register 12. Therefore, 1 from the output of the element OR 10

passes through the element And 6, open potential 1 from the output of the trigger 13 to the output 11 of the device as a signal to perform a given command.

In the second mode, the device operates as follows.

When a codogram arrives with an alert signal, one of the jx outputs, for example, decoder 5, receives a signal that passes through the OR element 9 to the single input of trigger 14 and transfers it to state 1. The same happens when the signal arrives at input 19 from the sensor of the occurrence of special conditions on the object.

In such a case, the unit potential from the output of the trigger 14 through the element OR 10 is fed to the second input of the element AND 6, and in the case of the arrival of a codogram with the specified command, the trigger 13 is transferred to the single state. The signal from its output passes through the element And 6 to output 11 as a signal to execute a given command.

The positive effect from the use of the proposed device consists in a fundamentally new solution to the problem of increasing the accuracy of the execution of a given command on such objects. multi-level ACS, where there are no people and where there is a need for the highest accuracy in the execution of a given command (for example, to turn on the fire extinguishing system, to commission the object, etc.). At the same time, during the long-term operation of the object, it is required to minimize the possibility of performing a given team due to randomness of the appearance of a false codogram with a given command due to erroneous actions of operators, etc. If, on the other hand, special conditions are detected either by the sensor on the object itself or by control points that send the corresponding warning signals to the object, the main thing is to ensure high speed of execution of the specified command. It is optimal to resolve these contradictions of both modes and allows the proposed device. F o rmula of the invention; A device for receiving remote control commands, containing a generator im0
