应用于海事上的便携式北斗报警终端设计

针对海洋环境复杂多变,没有手机等无线通信网络的特点,为了及时准确的报警,结合北斗一代卫星通信短报文的独特功能,设计了一款体积小、重量轻的北斗报警终端,主要应用于海事活动中的应急报警,可随身携带,配备到每个船员。终端采用业界体积最小的北斗通信四合一模块BGM7014,通过单片机控制,实现了遇险后,可主动申请定位,并把遇险信息和位置信息发射出去。经测试表明,终端可以实现遇险报警功能,且定位通信成功率均在95%以上。

Design of Portable Beidou Alarm Terminal for Maritime

Due to the complicated and changeable environment and the absence of wireless communication network on the sea,it is very difficult to alarm timely and accurately in a maritime emergency.This paper designs a small portable Beidou alarm terminal which can auto alarm through Beidou satellite. The small terminal can be equipped to a single mariner. The terminal can auto position and transmit the dangerous info and geographic position to rescue platform through Beidou satellite. The smallest Beidou communication 4- in- 1 module,BGM7014,is used in this terminal. All programs are executed by MCU. Tests show that the terminal position and communication success ratio can run up to 95%.
