DEVICE FOR DYNAMIC BODY DETECTION AND METHOD FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To realize remote detection of a dynamic body in a detection target area without depending on thermal detection.SOLUTION: A device for dynamic body detection comprises: m (m≥1) units of transmitters 20 that are arranged dispersedly in a detection target area 50; a receiver 30 that measures each field intensity generated from the transmitters 20 while identifying each intensity from the respective transmitters 20; and a processing unit 40 that processes m pieces of time-series field intensity data. A matching circuit between an antenna and a transmission circuit in the respective transmitters 20 includes a capacitance sensor of which capacitance varies with the presence of a dynamic body. The processing unit 40 comprises: difference histogram creation means 44 that sequentially obtains a difference per unit time with respect to each piece of the time-series data and then creates difference histogram; and determination means 45 that compares all the generated difference histogram for all pieces of the time-series data with one another and then determines whether or not the dynamic body is present in the detection target area 50.
