SYSTEM FOR RECEIVING-TRANSMITTING, CONTROLLING AND PROCESSING DATA Russian patent published in 2013 - IPC G08B25/10 H04L29/06 H04W92/00 

FIELD: information technology.

SUBSTANCE: system has a receiving-control device having a subsystem for expanding wireless zones with a module for expanding wireless zones to provide two-way radio communication for constant control of the communication channel of wireless sensors and the receiving-control device on an internal communication bus; the sensors are configured form a data packet of control-diagnostic messages consisting of a pseudorandom encryption byte, a unique sensor number and packet index number, the message itself, the signal level of the previous received response from the corresponding module for expanding wireless zones and noise level in the sensor zone, and fitted with a transceiver for transmitting the data packet to the corresponding module for expanding wireless zones of the receiving-control device.

EFFECT: high reliability of the system and cryptographic protection of data transmission channels in order to reduce the probability of a security and fire alarm system being bypassed by intruders, interfacing a central monitoring system with digital communication channels.
