中文摘要：

为了解决了海上作业人员遇险救援不便的问题,开发了一种基于北斗二代卫星导航系统的落水遇险人员报警定位终端.提出了以ARM Cortex-M3为控制核心的报警定位终端,采用无线传输模块可将海上作业人员的安全信息发送至附近搜救船舶或者海上作业平台,其一旦接收到报警信息能够对遇险者及时实施救援.实验结果表明,该终端具有成本低、定位精度高、工作稳定可靠和实用性强等优点.

英文摘要：

To solve the problem of inconvenient rescuing for operating people in distress at sea,an alarm positioning terminal for maritime fallen overboard people is developed based on the second generation BeiDou satellite navigation system.The alarm positioning terminal is presented which is used the ARM Cornter-M3 as the core,the information of security for the people with offshore job is sent to the nearby search-and-rescue ships or offshore platform by the wireless transmission model,once received the alarm information,rescuing is implemented timely.Experimented results prove that it has many advantages,such as the low cost of the terminal,high positioning accuracy,stable and reliable working property,high practicability and so on.
