摘要
为了快速、准确地实现对人工影响天气作业的响应,建立了一种基于Android的智能移动作业终端系统,详细介绍了该系统的总体框架、主要功能、操作流程,并重点围绕基本指令信息收发、移动GIS平台应用、视频传输应用3个方面,分别就其中的一些关键技术点如自适应心跳包、矢量栅格数据的传输及显示、终端GIS坐标转换、视频编码器的裁剪和优化、流媒体传输优化及差错控制进行了阐述。初步试验结果表明,该系统的特点及优势均较明显。
In order to realize the response of artificial weather modification conveniently and accurately,a intelligent mobile terminal based on Android was proposed.The overall frame,main function and operation process of the system was introduced in detail.Meanwhile,some of the key technology of sending and receiving of basic instructions,application of mobile GIS platform,video information transmission,such as self-adaptive heartbeat bag,raster data transmission and display,terminal GIS coordinate transformation,cutting and optimization of video encoder,stream media transmission optimization and error control were emphasized.The result of preliminary application tests showed that the features and superiorities of this system were all obvious.
