摘　　要：利用超声波和无线电相结合的定位技术设计了一套适用于ZigBee心电监护网络的定位系统。本文在分析ZigBee网络模型结构的基础上,采用TDOA测距技术和Bounding box定位算法实现了心电监护网络内的短距离定位;利用高性能微控制器、CC2430无线收发模块和超声波收发模块构建了定位系统中各关键节点的硬件平台和软件平台,并对整个定位系统的原型机进行了测试。测试结果表明,该系统定位精度较高,具有较好的推广价值。One kind of localization system for ZigBee electrocardiograph telemonitoring network was designed by ultrasonic and radio positioning technologies. Based on the analysis of ZigBee network model structure, the short-range orientation was realized by making use of TDOA technology and Bounding box localization algorithm. The hardware and software platform of the crucial nodes was constructed using high performance microcontroller, CC2430, uhrasonic and radio modules. And the prototype test of the whole system was carried out. Test result indicates that the localization system has high precision and good practical significance.
