基于ZigBee定位与无线数据传输技术，设计了一种针对养老机构的老年人移动体征监测系统。该系统可实现体征(脉搏、心电、血氧)监测、人体定位与紧急情况报警。基于脉搏信号的移动采集与存储实验验证了该系统的有效性，脉搏测量范围为(50-170)次/分，测量平均误差小于3%，定位平均误差小于4 m，系统数据传输速率为250 kbps。该系统可有效实时地对养老机构中的老年人的健康与安全状况进行监护，对老年人生命安全保障具有重要意义。

This paper proposed a mobile vital-signs monitoring system based on ZigBee localization and wireless transmission technology for the elderly in nursing home. The system can monitor the vital-signs (pulse, ECG and blood oxygen), localize human body and warn in emergency. The validity and accuracy of this system were testified by the experiments of mobile acquisition and storage of pulse. In these experiments, the measurement of pulse ranged from 50 to 170 time a minute, the mean error of which was less than 3%. The mean error of localizing was less than 4 m. And the data transmission rate was 250 kbps. The system, which effectively conducts the real-time monitoring of the health and safety situation for the elderly, has a great significance for protecting the elderly's life safety.
