SENSOR DEVICE, SENSOR MANAGEMENT SYSTEM, METHOD FOR CONTROLLING SENSOR DEVICE, PROGRAM, AND COMPUTER-READABLE RECORDING MEIUUM

摘要

This sensor device (1) is provided with: a difference calculation unit (1311) that calculates the difference between a predetermined threshold and a current measured value measured by a sensor unit (12) that measures a measurement subject; an operation-setting-parameter recording unit (16) that records the maximum amount of change of the measured value with respect to elapsed time on the basis of a plurality of measured value history records; a minimum time calculation unit (1312) that calculates the minimum arrival time that is the minimum time for the measurement subject to arrive at the predetermined threshold from the current measured value on the basis of the calculated difference and the maximum amount of change; a measurement time determination unit (132) that determines the time of the next measurement of the measurement subject from whichever time is the greater of the minimum arrival time and the minimum time interval at which the sensor device (1) can measure; and a sensor control unit (13) that controls the sensor unit (12) in a manner so as to measure the measurement subject at the determined time.
