基于ZigBee的定位及体征监测系统的设计与实现

The design and implementation of monitoring system for location and physical signs based on ZigBee

针对当前幼儿园儿童等特殊人群自我保护能力差,管理人员监管不及时的特点,以及目前市场上定位工具造价高的问题,基于RSSI(Received Signal strength Indicator)测距技术和ZigBee技术,设计开发了一套低成本的定位及体征监测系统。该系统的整体设计是基于CC2530高性能处理器以及LEA-6S这款GPS芯片,同时在PCB(Printed Circuit Board)集成了红外线温度传感器。采用ZigBee协议建立网络,以GPS与RSSI联合定位的形式对目标节点进行定位,通过服务器对配带定位装置的人群进行信息采集,最终通过Web端或手机移动端来查看信息。

In view of the poor self-protection ability of the high risk population like pre-school children,the belated management regulation,and the high cost of positioning tool,a set of low-cost monitoring system for the high risk population's location and signs was designed based on RSSI(Received Signal strength Indicator)ranging technology and ZigBee technology.The overall design of the system is based on the high-performance processor CC2530and the GPS chip LEA-6S,and the infrared temperature sensor is integrated in the PCB(Printed Circuit Board).The ZigBee protocol is adopted to establish the network.The location information is obtained by the combination of GPS and RSSI.Meanwhile,the server gathers the information from people who equipped with locating device.Finally,we can view the location and the physical sign information by the web client or mobile terminal.
