脑肌电多设备集成系统的接口硬件设计

Hardware design of interface for integrated brain-controlled system

脑肌电控制是使用人的脑电和肌电信号对设备进行控制的新型人机控制方式。为了方便其多设备类型集成控制系统的构建,设计了一种兼容多设备控制信号的新型脑肌电控制系统信号接口,详细描述了其3层结构工作原理、不同模式的工作流程以及各功能模块的硬件设计。接口还具备针对误操作的安全保护功能,该功能采用显示反馈和二次确认的方式实现,可以有效优化控制系统的安全性能。

Brain control is a new man-machine control method using electroencephalogram （EEG） and electromyography （EMG） to control the device. In order to facilitate its multi-device integrated control system construction, a design of a new compatible multi-device control signal interface is presented. Meanwhile, its working principle of three-tier structure, work processes in different modes and hardware design of the functional modules are described in detail. By ways of display feedback and confirmation alert, the interface also includes a security function, which can effectively improve the safety control system.
