【摘要】：移动视频监控系统是以智能手机、平板电脑等移动设备作为接收端,从而实现便携,实时查看与预警,远程监控等功能。“和谐社会”、“平安城市”等概念的提出以及人们自身安防意识的提高等为视频监控行业注入了强而有力的市场驱动力。在这样的背景下,移动视频监控系统已经成为人们争相研究的热点。IOS是苹果公司为其智能移动产品iPhone和iPad所开发的操作系统,其以高分辨率,高智能性,高流畅度及丰富的软件支持等优势受广大消费者的青睐。本文对基于IOS操作系统的移动视频监控客户端进行了设计和实现,主要内容与创新点如下：1.针对目前手机客户端软件的高用户体验、易操作需求,研究了IOS操作系统的界面控件框架,设计了多种自定义类型的控件作为视频监控客户端的界面布局,从而提高视频监控客户端的美观、易操作等特性。2.分析了视频解码率对于视频监控画面清晰度的影响。针对IOS操作系统自带的视频框架支持的视频解码格式少、解码率不高等情况,移植了FFmpeg开源视频解码库,同时研究并优化了其解码过程,提高了视频监控客户端的解码率,并且支持多种常见的视频格式,为视频监控客户端的画面清晰显示和扩展性等提供了有力支持。3.针对视频监控客户端中语音对讲的需求,研究了IOS操作系统自带的Core Audio中的Audio Toolbox框架,设计了音频队列来对采集到的音频数据进行编解码和传输处理,最终实现了视频监控客户端的语音功能。4.针对设备捕捉到的异常信息,设计了报警推送功能。通过研究IOS操作系统的远程推送通知机制,采用了IOS操作系统中的APNS技术,结合视频监控中心,报警服务器和苹果服务器,将前端监控设备采集到的异常信息自动推送到用户手机上,从而及时对用户作出预警。
[Abstract]:Mobile video monitoring system based on smart mobile phone, tablet computer and other mobile devices as the receiver, in order to achieve portable, real-time view of remote monitoring and early warning, and other functions. The "harmonious society", "into a powerful driving force of the market concept of safe city" is put forward and the people's security awareness for the video to monitor the industry. In this context, the mobile video monitoring system has become a hot topic of.IOS people competing Research Institute of Apple Corp is the operating system for the development of intelligent mobile products iPhone and iPad, with its high resolution, high intelligence, high fluency and rich software support and other advantages favored by the vast number of consumers in this paper. The design and implementation of mobile video surveillance client based on IOS operating system, the main contents and innovations are as follows: 1.. Aiming at the high mobile phone client software user experience Easy operation, demand, the interface of the control framework of IOS operating system, design a variety of custom type controls as interface layout video monitoring client, so as to improve the video monitoring client appearance, easy operation and other characteristics of.2. video decoding rate for video monitoring picture clarity. Support for video frame with IOS operating system the video decoding format, decoding rate is not high, the transplantation of the FFmpeg open source video decoding library, we investigated and optimized the decoding process, to improve the video monitoring client decoding rate, a variety of common video formats and support for video surveillance client images clearly show the scalability and provides strong support for.3. according to voice intercom video monitoring client demand, on the Audio Toolbox framework Core Audio comes with the IOS operating system, design Codec and transmission of audio data processing of the collected audio queue, finally realized the abnormal information of.4. voice video monitoring client equipment for capture, the design of the alarm push function. Through the research on remote IOS operating system push notification mechanism, using the IOS operating system in the APNS technology, combined with the video monitoring center server, alarm and apple server will be automatically pushed to the user mobile phone abnormal information collected on the front-end monitoring equipment, and timely warning to the user.
