SYSTEM FOR REMOTE READING OF SENSOR INDICATIONS Russian patent published in 2017 - IPC G08C17/02 

FIELD: measuring equipment.

SUBSTANCE: system for remote sensing of sensors consists of a network of data transmission devices, each of which consists of a series-connected sensor, a processor and a first radio module, a data receiving device consisting of a second radio module, a second processor and a computer connected in series. The data transmission devices are divided into m groups of n data transmission devices, the first radio module comprises a spread spectrum receiver and a narrow-band transmitter, the second radio module comprises a noise spreading signal transmitter and a first narrowband receiver, n-1 or more are input to the second radio module Narrow-band receivers whose inputs are connected to the input of the first narrow-band receiver, and the outputs to the second processor, the spreading factor of the transmitter with noise-like signals is selected greater than 10, and the data rate of the narrowband transmitter is less than 480 bps.

EFFECT: increasing the range of radio communication due to the possibility of a significant increase in the sensitivity of the receiving path while maintaining the total information rate of the sensors interrogation.
