心室复极高频波是一种微伏级的心电信号,是用于心脏猝死风险预测的新工具,为检测这种信号设计了心室复极高频波检测仪,用于信号的采集和传输,应用ZigBee技术实现网络化的心室复极高频波检测的多点监控、无线传输。文章介绍了ZigBee的技术特点以及在心室复极高频波检测仪中的应用优势,并应用基于ZigBee技术的CC2430芯片,构建心室复极高频波检测的硬件系统。在开放的协议源码基础上,编写了心室复极高频波的软件系统。通过实验验证,其组网方便,可以实现多点监控。同时方案具有低延时、低功耗、系统稳定、传输抗干扰高等特点,单芯片设计有效减小心室复极高频波检测仪的体积。实现了项目的预期目的。
The high frequency ventricular repolarization waves （HFVRWs） is a micro - volt level electrocar- diogram signal which can be used to predict the risk of sudden cardiac death. A new system was designed for the detection and transmission of the HFVRWs and the ZigBee technology, such as the multi - point monitoring and ~control and wireless transmission were used for the network of this system. In this paper, we presented the technol- ogy characteristic and its application advantage in the HFVRWs detection system and designed and then design the detection system using the CC2430 chip which was based on the ZigBee technology, writed the HFVRWs detection system software based on the open source protocol code. Experiments show that, this method has the advantages of easy to form network and multi - point monitoring and control. At the same time, this system has the merit of little time delay, low power dissipation, high stability and anti-jamming transmission, etc. Moreover, the singlechip design can effectively reduce the volume of the system. All above achieve the intended purpose of the project.
