The present invention provides a security monitoring wearable device that includes a direction detector, an acceleration detector, a communication unit, and a controller. The controller is configured to receive a first monitoring signal monitored by the direction detector and a second monitoring signal monitored by the acceleration detector, and confirm whether the patient has a falling state according to the first monitoring signal and the second monitoring signal. When the patient is determined to have a fall state, the patient abnormal state information is output to the security monitoring terminal to notify the rescuer. The invention provides a security monitoring system, and the security monitoring wearable device establishes a communication connection with a security monitoring terminal used by a rescuer. The security monitoring device can be conveniently carried by patients, and the patient's safety status can be monitored in real time to provide rescuers with prime time for proper disposal.本發明提出一種安全監控穿戴式裝置,該穿戴式裝置包括方向檢測器、加速度檢測器、通信單元及控制器。控制器用於接收方向檢測器監控的第一監控信號及加速度檢測器監控的第二監控信號並根據上述第一監控信號及第二監控信號判斷患者是否存在跌倒狀態,當確定患者存在跌倒狀態時輸出患者異常狀態資訊至安全監控終端以通知救援人員。本發明提供了安全監控系統,安全監控穿戴式裝置與救援人員使用的安全監控終端建立通信連接。安全監控式裝置可方便患者攜帶,實時監控患者的安全狀態,為救援人員提供黃金時間進行適當的處置。
