摘要:
基于表面肌电信号的无线交互控制系统能够带来更为直接自然的交互控制方式。首先根据表面肌电信号的特点设计了信号拾取调理电路,对其进行前置差分放大、滤波和后置放大抬升,以满足信号采集的要求; 接着对信号进行采集并将采集数据通过ZigBee无线传输给交互控制器; 然后通过交互操作平台完成控制指令转换控制智能小车的行驶; 最后对信号的拾取、采集、无线传输以及小车行驶进行了验证实验。实验表明拾取采集肌电信号满足系统需要。在发射强度为4.5 dBm、传输速率约25 kbps时,室外40 m以内、室内30 m以内可以有效可靠地进行采集数据的传输; 基于小臂肌电信号MAV(Mean Absolute Value)的强弱可以实现小车的启停和加减速控制。本系统的构建为在肌电信号无线控制、康复娱乐等领域进行应用拓展提供了一种有效可行的实现方案。
Abstract:
The wireless interactive control system based on sEMG signals would be more direct and natural. Firstly, according to the characteristics of sEMG signal, the pickup signal conditioning circuit was designed to meet the requirements of the subsequent signal acquisition, including the pre-differential amplifier circuit, filter circuit and post amplification and level rise circuit. Then the signal acquisition was done and the results were transmitted to the interaction controller through ZigBee wireless mode. Then the controlling instructions of car driving through were transferred and the interaction control was realized. Finally the signal pickup, acquisition, wireless transmission and car travel were tested. The results show that the signal data met system requirement. The transmission of acquisition data below 40 meters outdoor and 30 meters indoor were effective and reliable at 4.5 dBm emission intensity and about 25 kbps transmission rate. The start, stop, acceleration and deceleration control of car is based on sEMG signal MAV. The developed sEMG-based wireless interaction control system can be used for wireless control and rehabilitation applications.
