摘要
本文设计了一套基于生物反馈的智能化神经康复治疗仪。采用DSP+CLPD的新型设计思想,利用CPLD芯片实现刺激器的主要硬件电路的设计,实现了刺激参数的数字式可调,简化了电路;使DSP从繁复的工作中解放出来,专注于肌电采集、人工智能判断、阈值调整,并控制键盘液晶实现刺激参数的显示;并通过串口与上位机通信,提供友好的人机交互界面。
In this paper, an intelligent neural healing instrument based on biofeedback is developed. In addition, a novel developed method is proposed and implemented by Digital Signal Processor （DSP） and Complex Programmable Logic Device （CLPD）. A CPLD- based stimulator is used to generate a wide range of stimulating pulses. Thus, a DSP-based controller is released from complicated work. It can be absorbed in gathering for electromyographic （EMG） signals and judging for artificial intelligence, and implement selective parameters display simultaneously. Besides, a user-friendly interface has also been developed using series port to communicate with host computer, which can offer case history database management and EMG wave dynamic display.
