[Abstract]:Surface EMG signal (Surface Electromyography, SEMG) is the bioelectric change of neuromuscular system which is guided by the skin surface. The one dimensional time series signal. SEMG signal can reflect the relationship between nervous system control and muscle movement. And it has the advantages of non-invasive detection, so it has a wide range of applications in the field of medical rehabilitation, such as disease diagnosis, sports medicine, prosthetic control, remote control robot, virtual reality, gesture recognition and other human-computer interaction fields. Based on the research of surface EMG signal acquisition system and wireless communication technology of sensor network at home and abroad, this paper focuses on the acquisition and transmission of multi-channel signals according to the actual requirements of the project. An array surface electromyography (EMG) acquisition and transmission system based on WIFI high speed wireless transmission technology is designed. In order to ensure the consistency and synchronicity of the system data collection, and overcome the difficult problem of the system's massive data transmission, this paper proposes a kind of data acquisition node, data gathering center and the upper computer client, which is composed of the data collection node, the data gathering center and the upper computer client. The data acquisition and transmission network (CSN-WIFI), which combines the wired wireless network, and designs the strict synchronization, real-time and fast data transmission protocol according to the characteristics of the network, including time synchronization mechanism, pipeline data aggregation technology and so on. The synchronization methods between different collection nodes are introduced in detail. The effects of data aggregation cycle on the throughput, delay, packet loss rate and system energy consumption of the transmission network are analyzed. The experimental results show that the whole system can simultaneously collect 128-channel EMG signals on the forearm surface of human body, and realize the wireless real-time transmission of signal data based on TCP/IP protocol. The throughput of the whole transmission network is 2 Mbpss, the delay is less than 0.1 s, and the packet loss rate is less than 1, which lays the foundation for the research of a new generation of man-machine interaction based on surface EMG signal.
