摘要
我国是世界上自然灾害最严重的国家之一,尤其是近几年来,全球气候变暖和厄尔尼诺现象愈加严重,我国各地频发灾害,加之各种灾害难以预测,人员损失和经济损失逐年剧增。严峻的灾害形势迫切要求我国不断提升综合减灾与救灾能力。本生命探测系统以CDMA定位技术为支撑,融合应急基站手机定位、Wi-Fi通信、基于MINA框架的网络通信、并行多线程开发等技术,通过系统内部交互的一系列服务协议,构建了多功能的定位服务系统,为用户提供了简洁美观、方便易用的用户界面。本生命探测系统实现了灾后复杂环境下高精度生命探测与定位,灾害现场搜救,应急指挥调度,应急减灾信息位置服务等功能。本文重点实现了生命探测系统嵌入式定位终端的硬件装置和软件平台的搭建,定位终端采用了嵌入式设备与MINA框架相结合的方法,具有一定的新颖性。测试证明,嵌入式定位终端与服务器端可以进行准确稳定地数据通信。
China is one of the most serious natural disasters in the world, especially in recent years, the globa lwarming and the El Ni?o phenomenon is more serious, frequent disasters in China, combined with various disasters is difficult to predict, personnel losses and economic losses year after year. The severe disaster situation urgently requiresour country to continuously improve the comprehensive disaster reduction and disaster relief capability. The life detection system is based on CDMA positioning technology, which integrates mobile base station positioning, Wi-Fi communication,network communication based on MINA framework and parallel multi-thread development. Through theseries of service protocols, the multi-functional of the positioning service system, to provide users with a simple and beautiful, easy to use user interface. The life detection system to achieve the complex environment of the post-disasterdetection and location of high-precision life, disaster scene search and rescue, emergency command and dispatch,emergency disaster reduction information location services and other functions. This paper focuses on the hardwaredevice and software platform of the embedded positioning terminal of the life detection system. The positioning terminal adopts the method of combining the embedded device and the MINA framework, which has certain novelty. Tests prove that the embedded positioning terminal and the server end can carry out accurate and stable data communication.
