INTRUDING OBJECT DETECTION METHOD, DEVICE AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To detect and track an intruding object by positioning a plurality of structurally simple intruding object detection devices 5 in a field of detection. SOLUTION: A radio sensor network is configured in advance for connecting the intruding object detection devices 5 positioned in advance in a detection area and provided with a sensor node 6 and at least one sensor 8 to a monitoring apparatus 1. The monitoring apparatus 1 extracts detection information about an intruding object 14 from radio signals periodically transmitted by the intruding object detection devices 5 to the monitoring apparatus 1 and determines which intruding object detection devices 5 have transmitted the radio signal information, to detect the position of the intruding object 14. The monitoring apparatus 1 receiving the detection information about the intruding object 14 records the position of the intruding object 14 at time intervals to track the behavior of the intruding object 14.
