The present disclosure relates to a physiological parameter monitoring system employed in an electronic device. The physiological parameter monitoring system includes a time setting module, a frequency spectrum processing module, a counting module, and a determining module. The time setting module actuates a sensor to sense physiological parameters of users so that the sensor outputs frequency spectrum signals. The frequency spectrum processing module processes the frequency spectrum signals. The counting module counts each time when the frequency spectrum signals pass through the frequency spectrum processing module. The determining module determines whether a total count is greater than a constant, and activates an indicating device when the total count is greater than the constant.本發明提供一種生理參數監控系統,其應用於電子裝置,該生理參數監控系統包括:時間設定模組,用於啟動生理參數感測器以感測用戶的生理參數,並輸出頻譜訊號;頻譜處理模組,用於處理由生理參數感測器傳送的頻譜訊號,以便高於一窗口頻帶的頻譜訊號通過;計數模組,用於作一次計數以響應頻譜訊號通過窗口頻帶;判斷模組,用於判斷在預設時間內累計的計數是否超過一常數,若在預設時間內累計的計數超過該常數,控制一提醒裝置開啟以輸出提醒訊號。1‧‧‧電子裝置10‧‧‧生理參數監控系統101‧‧‧時間設定模組102‧‧‧頻譜處理模組103‧‧‧計數模組104‧‧‧判斷模組11‧‧‧生理參數感測器12‧‧‧記憶體13‧‧‧處理器14‧‧‧提醒裝置
