摘要
提出了一种基于FPGA开发设计用于神经康复治疗仪的刺激器的方法.利用FPGA来实现刺激波形的发生、刺激频率、脉宽和幅度的数字式可调.该方法简化了电路,提高了系统的可扩展性;并把微处理器从繁复的工作中解放出来,专注于肌电采集和人工智能判断,提高了实时处理能力.经仿真和电路测试证明,刺激波形输出准确可靠,能很好满足性能要求.
A way based on FPGA is adopted to devise the stimulator for neural healing instrument,which implements the occurrence of stimulating wave and the digital adjusting for stimulating frequency,pulse-width and amplitude.For the use of FPGA,circuit is simplified and expansibility is enhanced,moreover microprocessor can be released from complicated work and can be absorbed in gathering for EMG and judgment for artificial intelligence.Therefore the ability of real-time processing is also improved.The output wave b...
