大鼠刺激器遥控系统的设计与实现

设计并实现一个基于C8051F410和nRF905芯片的大鼠遥控刺激系统。该系统由监控软件、发射器和刺激器构成，运行在PC机上的监控软件可以设置参数并发出控制指令，指令经USB传输进入发射器后被发送出去，刺激器接收指令后产生刺激信号，对大鼠的运动进行控制。刺激脉冲幅值可调，改变刺激参数可实现不同的运动控制。无线通信采用跳频方式，提高了抗干扰性。刺激器体积小、质量轻。实验结果表明，在200 m的范围内，系统工作稳定。

Design and Implementation of Remote Control System for Rat Stimulator

A remote control system for rat micro-stimulator system is described. The system mainly consists of the following parts: control platform based on PC, transceiver, and stimulator. The control command is transmitted from control software by wireless transceiver and is received by stimulator which sends stimulation pulses to the rat brain to control the rat motion. The amplitude of stimulation pulse can be regulated and it is easy to set the proper stimulation parameters for different motion controls. Frequency hopping is also applied to improve the reliability of wireless communication. Moreover, the system is small and light as a result of using SMT components. Experimental results show that the system runs steadily within 200 m.
