METHOD TO DETECT ENVIRONMENT POLLUTION AND DEVICE FOR ITS REALISATION Russian patent published in 2011 - IPC G08B25/00 

FIELD: ecology.

SUBSTANCE: values of environment pollution parameters measured by sensors built into mobile phones are compared to rated values, if a rated value is exceeded, alarm signals are generated, which are sent via a telephone communication operator directly to a centralised device of alarm signals reception, where, with the help of a telephone operator, location of alarm signals sources is detected, at the same time for two or more registered alarm signals coordinates of their sources are compared, and the minimum distance L_ik is identified between the compared i and k sources, and also a period of time Δt_ik min between origins of signals, and if values L_jk and Δt_{ik min} are less than the rated permissible values, an emergency signal is generated.

EFFECT: improved efficiency of system operation by reduced quantity of false alarm signals.
