中文摘要：

设计了一种无线多通道电刺激系统,硬件部分包括了无线通信模块和神经刺激器单元2部分,后台软件包括了基于LabVIEW的上位机控制。无线通信部分用了包含基于蓝牙形式的串口通信通道和基于2.4 G无线收发的2个通道部分.以方便调试和实际远程遥控。神经刺激器单元包含了常见的锂电池3.7 V供电升压电源电路、STM32最小系统、双极性压控恒流源电路、4通道模拟开关等模块。为了实现多点的并发控制,本刺激器模块有4个通道的单独输出,同时能实现其中任意两个通道的同时输出,每个通道的恒电流波形参数如脉冲频率、占空比、强度、簇个数等参数均可独立设置。实验结果表明：在负载阻抗低于10 kΩ的情况下,本无线多通道动物神经刺激系统可以实现500 m左右的实时多通道远程控制。

英文摘要：

A wireless multi-channel nerve electrical stimulation system is designed,the hardware contains wireless communication part,nerve stimulator,the control software includes software based on labVIEW.Wireless communication module contains communication module based on Bluetooth and 2.4 G remote control transceiver,to facilitate debugging and actual remote control.Nerve stimulator unit contains the common lithium battery 3.7 V boosting transformer circuit,STM32 minimum system,bipolar voltage controlled constant current source circuit,4-channel analog switch.In order to realize the multi-point simultaneous control,the stimulator has four separate output channels and arbitrarily two of the four channels can realize concurrent output.Each channel has configurable waveform parameters such as pulse frequency,pulse rate,intensity.The result of the experiment shows that under load lower than 10 kΩ,this wireless multi-channel nerve stimulation system can realize real-time multi-channel remote control of about 500 meters.
