<P>PROBLEM TO BE SOLVED: To provide a radio sensor system which can obtain high accuracy environmental information by transmitting the measured values of sensor devices to a base station, calibrating the measured values, and correcting the converted physical quantities. <P>SOLUTION: The radio sensor system comprises radio sensors which are provided at a plurality of points and acquire and transmit measured values, corresponding to ambient environmental information by sensor devices and a data collection terminal which is provided in the base station and receives measured values from radio sensors and calculates and collects environmental information. Each radio sensor has a sensor for measuring environmental information based on the physical characteristics of the sensor device and a radio transmitting/receiving part for transmitting the measured values by radio, and the data collection terminal has a conversion information storage part wherein physical characteristics of sensor devices of registered radio sensors and conversion information for conversion from measurement values to environmental information are stored for each radio sensor and a conversion part for performing arithmetics, to convert measured values to environmental information by physical characteristics and conversion information corresponding to the radio sensors. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
