摘要
针对当前老年人易走失的现状,以及目前市场上基于GPS定位技术构建跟踪装置的局限性,本文设计出一种采用Zigbee技术的防走失装置。通过构建无线传感器网络,在小区、疗养院等小范围活动区域内,对老年人群的相对位置进行动态监测,确定其运动范围,在其即将脱离监控范围时及时报警提示。本装置体积小、耗电少,能在复杂环境下使用。
With the current situation that the elderly get lost easily, as well as the limitations of the tracing devices based on the GPS locating technology in the market nowadays, a new anti-lost device based on the Zigbee technology is designed. By constructing a wireless sensor network in special areas such as the residential districts, the sanatoriums and so on, the relative position and moving range of the monitored elderly can be displayed in time, which also gives alarm when the object is going out of the monitored area. The whole device is small, low power consumption, and can be used in complicated environments.
