A system and a method for judging abnormal condition based on center of gravity are provided. By determining a location and a center of gravity of a cared person, and judging the cared person occurs abnormal condition when a distance between the location and the center of gravity is greater than a warning distance, the system and the method can judge the cared person occurs abnormal condition when the cared person can move, and can achieve the effect of reducing misjudgment rate of cared person occurs abnormal condition.一種依據重心位置判斷異常狀況之系統及其方法,其透過依據壓力訊號判斷被照護人的所在位置以及重心位置,並判斷重心位置與所在位置之間隔達到警示距離時,判斷被照護人產生異常狀況之技術手段,可以在發生異常狀況的被照護人未喪失移動能力時,判斷出被照護人發生異常狀況,並達成減少被照護人發生異常狀況之誤判機率的技術功效。步驟510‧‧‧於生活空間之地板上鋪設感壓模組步驟520‧‧‧主控端依據被照護人之生理資料計算警示距離步驟530‧‧‧當被照護人與感壓模組接觸時,感壓模組依據被照護人接觸時所給予之壓力產生對應之壓力訊號步驟540‧‧‧感壓模組傳送壓力訊號至主控端步驟550‧‧‧主控端依據壓力訊號判斷被照護人之所在位置步驟560‧‧‧主控端依據壓力訊號判斷被照護人之重心位置步驟570‧‧‧主控端判斷重心位置與所在位置之間隔達到警示距離時,判斷被照護人產生異常狀況步驟580‧‧‧主控端傳送警示訊息至特定裝置
