Environment change detection system, environment change detection method, and environmental change detection program

摘要

An environmental change detection system, an environmental change detection method, and an environmental change detection program in which a detection device does not have a communication function are provided. The environment change detection system 1 includes a power supply unit 300, a detection unit 310 that detects a state of the environment within the detection range, a determination unit 320 that determines a change in the environment within the detection range, and a determination unit 320 A power supply load modulation section 330 for performing modulation control to cause the power supply section 300 to consume the load current having the characteristic, a data detection section 100 for detecting and measuring the current data including the load current modulated by the modulation control, A data converting unit 110 for converting the digital power data into digital power data, a separating unit 210 for separating the modulated current data of the power supply unit 300 from the digital power data, and analyzing the modulated current data separated by the separating unit 210, And an analyzing unit 220.
