| Abstract: | A wearable fall detection system based on multi-sensor is designed to monitoring the falls event in elderly persons.Acceleration sensor and pressure sensor are combined to independent acquisition real-time data.Using threshold and vote algorithm based on two judgments to improve the recognition rate of the fall monitoring system.For receiving timely assistance,real-time monitoring elderly people life events to remind misjudgment or inform their families.Experimental results show that the system has higher recognition rate and reliability,which suitable using in the fall monitoring system. |
