OPENING DETECTION SYSTEM

To provide an opening detection system capable of detecting opening of a heat-insulating storage body even without a dedicated radio wave transmitter.SOLUTION: An opening detection system is an opening detection system 100 comprising: an opening detection device 110 that detects opening based on a receiving condition of radio wave; and a storage body 130 that stores an article and the opening detection device. The storage body has: a heat insulating layer 131 surrounding a storage space 133; and a radio wave blocking layer 132 that is placed around the heat insulating layer and blocks the radio wave. The opening detection device has: a control unit 110a that controls an entire unit of the opening detection device; a temperature sensor 110e; and an antenna unit 110d. The temperature sensor and the antenna unit are arranged in the storage space, and the control unit is arranged between the heat insulating layer and the radio wave blocking layer.SELECTED DRAWING: Figure 1 【課題】 専用の電波発信機がなくても、断熱性の収納体の開封の検知が可能な開封検知システムを提供する。【解決手段】 電波の受信状態に基づいて開封を検知する開封検知装置１１０と、物品及び開封検知装置を収納する収納体１３０と、を備えた開封検知システム１００であって、収納体は、収納空間１３３を囲む断熱層１３１と、断熱層の周囲に配置され、電波を遮断する電波遮断層１３２と、を有し、開封検知装置は、開封検知装置の全体を制御する制御部１１０ａと、温度センサ１１０ｅと、アンテナ部１１０ｄと、を有し、温度センサと、アンテナ部は、収納空間に配置され、制御部は、断熱層と電波遮断層の間に配置されている、開封検知システム。【選択図】 図１
