PROBLEM TO BE SOLVED: To provide a heat stroke prevention system for surely preventing onset of heat stroke by interrupting work of a worker when there is the risk of onset of heat stroke.SOLUTION: The heat stroke prevention system 10 comprises a portable device 14 to be detachably put on clothes of each worker and a monitoring device 11 for monitoring onset risk of heat stroke. The portable device 14 includes: a temperature sensor for measuring an intra-clothes temperature of the worker a humidity sensor for measuring intra-clothes humidity of the worker a first transmission means for transmitting the intra-clothes temperature and the intra-clothes humidity to the monitoring device 11 a first reception means for receiving the onset risk alarm of heat stroke from the monitoring device 11 and a transmission means for transmitting the onset risk alarm received from the monitoring device 11 to the worker. The monitoring device 11 includes: a second reception means for receiving the intra-clothes temperature and the intra-clothes humidity from the portable device 14 and a second transmission means for transmitting the onset risk alarm to the portable device 14 when it is recognized that the onset risk of heat stroke is high on the basis of the received intra-clothes temperature and intra-clothes humidity.COPYRIGHT: (C)2013,JPO&INPIT【課題】熱中症の発症危険性がある場合、作業者の作業を中断させて熱中症の発症を確実に予防する熱中症予防システムを提供する。【解決手段】熱中症予防システム10は、各作業者の着衣に着脱可能に装着させる携帯装置14と熱中症の発症危険性を監視する監視装置11とから形成され、携帯装置14は、作業者の着衣内温度を測定する温度センサと、作業者の着衣内湿度を測定する湿度センサと、着衣内温度と着衣内湿度とを監視装置11に送信する第1送信手段と、熱中症の発症危険性警告を監視装置11から受信する第1受信手段と、監視装置11から受信した発症危険性警告を作業者に伝える伝達手段とを有し、監視装置11は、携帯装置14から着衣内温度と着衣内湿度とを受信する第2受信手段と、受信した着衣内温度と着衣内湿度とに基づいて熱中症の発症危険性が高いと認められる場合、発症危険性警告を携帯装置14に送信する第2送信手段とを有する。【選択図】図1
