摘要:海上环境恶劣,海难事故突发,救援队伍如何能够快速高效地对落水求救人员进行定
位和搜救,是海上救援的工作重点和难点。本文介绍了基于 GPS 定位技术和 ZigBee 无线通
信技术的海上搜救报警系统的体系结构,系统组成,工作原理以及软硬件电路的设计,最后
对系统进行了功能测试。测试结果表明本系统不仅可以很好完成海上定位报警求救功能需
求,同时由于加入了 ZigBee 组网技术有效地降低了系统的功耗,延长了设备的使用寿命。

Abstract: Marine environment plex and maritime accidents occur frequently. How to locate
and rescue the person in distress quickly and effectively is a difficult but important work to solve
for the marine rescue team. The development of marine rescue alarm system based on GPS
positioning technology and ZigBee munication technology is discussed in this article,
including system architecture, ponents, software & hardware circuit design ,and then
the system function tests. The test results indicated that the system can not only plete the
requirements of maritime distress alarm function ,but also can effectively reduce the system power
consumption and extend the service life of the device due bining with the ZigBee
networking technology .
