DEVICE FOR SIMULATION OF PROTECTION OF GROUP OF CONTROLLED OBJECTS BASED ON LOGIC XOR Russian patent published in 2014 - IPC G08B25/00 

FIELD: fire safety.

SUBSTANCE: device of simulation of protection of group of controlled objects consists of a control unit comprising a management unit, a unit of generating of codegram of the next step, the generator of first pseudo-random sequence (generator of PRS-1), the modulator unit, the generator of second pseudo-random sequence (generator of PRS-2), the switchboard comprising a switching unit with N lines of communication, N units of comparison on the number of the controlled objects, each of which consists of a memory element of the value of the generator PRS-2 of the control unit (ME of the value of the generator PRS-2 of the control unit), the unit of logical operations XOR (logical operation "exclusive OR") consisting of n units XOR, on the number of bits in the binary representation of the codegrams of the first and second pseudo-random sequences, the memory element of the value of the generator PRS-2 of the controlled objects (ME of the value of the generator PRS-2 of the controlled objects), control unit of serviceability of the object and the controlled object, consisting of a unit of memory of the next step, the comparison unit, the demodulator, the memory unit, the matching device, the modulator, the generator PRS-2.

EFFECT: providing simultaneous protection of group of controlled objects connected independently from each other on the star topology, simplification of the technical implementation and improvement of the data processing rate.
