| Abstract: | This paper presents a wireless multi-sensor transmission system which can be applied to the elderly fall detection device. The system consists of wireless sensor node, base station that receives data and upper computer that processes the data. It mainly adopts the serial port interrupt way to receive and process the data in real-time, and can be applied to the accelerated velocity, angular velocity and gesture angle of the wireless acquisition in the elderly fall process. After the test, the system node and the upper machine have a high reliability and good real-time effect, which has a good application value in the security of the aged. |
