摘要

An environment measurement system that measures environmental conditions of a measurement object space, comprising:a fixed sensor terminal fixedly installed in said measurement object space;a mobile sensor terminal that moves in said measurement object space; andmeasurement means that measures the position of said mobile sensor terminal whereinsaid fixed sensor terminal measures environmental conditions neighboring an installation location of a self-terminal,said fixed sensor terminal and said mobile sensor terminal transmit or receive signals that perform positioning of the position of said mobile sensor terminal by wireless communication,said positioning means performs positioning of the position of said mobile sensor terminal using the signals, andsaid mobile sensor terminal measures environmental conditions neighboring the self-terminal while grasping the position of the self-terminal in said measurement object space using the positioning results.
