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 Lik is identified between the compared i and k sources, and also a period of time ötik min between origins of signals, and if values Ljk and ötik 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. ^ 8 cl, 2 dwg |
