基于nRF24L01的脑深部电刺激器（DBS）通信系统设计

脑深部电刺激器（DBS）是一个体外可编程的植入式脉冲电刺激器，通过体外控制器的参数设置，刺激相关靶点以达到医学治疗的目的。根据DBS的基本原理及设计要求，对DBS通信方式的选择及实现方案进行了分析，选用短距离无线通信模块nRF24L01设计了一种以ATmega48单片机为核心的无线通信系统。文中给出了相关软件控制流程。通过生物实验，证明了nRF24L01通信的可行性。本文设计的硬件系统简单可靠，软件编程容易，可方便的移植到其他控制系统中。

Design of DBS system based on nRF24L01

DBS is the programmable implantable pulse electrical stimulation device,which can achieve the purpose of medical treatment through setting parameter of controller in vitro and stimulating the relevant target. Based on the basic principles and design requirements of DBS and analyzing the means and program of communication, this article selects short-range wireless communication module nRF24L01 and uses ATmega48 MCU circuit as the core to constitute the wireless communication system. In this paper the Controlling Program Flow are given. Through biological experiments, It has been proved that the Communication feasibility on nRF24L01, this article shows that the design of simple hardware, easiness of Software programming and also can be easily transferred to other control svstem.
