【摘要】：隨著3G/4G移動通信網(wǎng)絡和計算機技術的快速發(fā)展,移動互聯(lián)網(wǎng)從很多方面改善了人們傳統(tǒng)的生活方式,3G/4G移動網(wǎng)絡具有帶寬寬、高安全性等突出特點,能夠突破長距離數(shù)字化無線監(jiān)控一直以來難以簡單實現(xiàn)的瓶頸,為無線視頻監(jiān)控開辟了一條新的道路。 在這種實際環(huán)境之下筆者設計了一種移動視頻監(jiān)控及定位系統(tǒng),為無線視頻監(jiān)控系統(tǒng)提出了一套完整的解決方案并進行了實現(xiàn)。該系統(tǒng)采用S3C6410處理器作為硬件基礎,以mjpg、mediastream、Live555、VLC等開源項目為核心,3G移動通信網(wǎng)絡作為網(wǎng)絡傳輸媒介,采用H.264編解碼方式實現(xiàn)視頻的采集傳輸播放,并集成GPS模塊進行位置數(shù)據(jù)的采集、傳輸、顯示,實現(xiàn)移動目標的視頻監(jiān)控、定位功能.該系統(tǒng)的前端硬件設備小巧,易于使用。系統(tǒng)終端硬件以ARM11架構的CPU為核心,軟件以基于嵌入式Linux操作系統(tǒng)的C語言及shell腳本設計,后臺PC端軟件集成了遠程控制、電子地圖顯示和視頻顯示功能,采用C#及HTML語言設計。在系統(tǒng)實現(xiàn)后期加入了硬件編解碼器MFC提高H.264編碼效率,并且根據(jù)開源的PHP飛信接口完成免費發(fā)送短信控制遠程終端的功能,而且還根據(jù)不同網(wǎng)絡環(huán)境制定了不同版本的軟件,并申請了一個使用新型專利。 本系統(tǒng)有機結合了計算機多媒體技術和移動互聯(lián)網(wǎng)技術,可以應用于多種行業(yè)的具體業(yè)務之中,可提高業(yè)務的信息化程度和人員的工作效率。本文的設計思路可廣泛用于車載監(jiān)控、無線視頻監(jiān)控等等領域,具有較廣泛的實用價值和推廣的意義。
[Abstract]:With the rapid development of 3G/4G mobile communication network and computer technology, mobile Internet has improved people's traditional way of life from many aspects. 3G/4G mobile network has the outstanding characteristics of wide bandwidth and high security. It can break through the bottleneck of long-distance digital wireless surveillance and open up a new way for wireless video surveillance. In this environment, a mobile video surveillance and positioning system is designed, and a complete solution for wireless video surveillance system is put forward and implemented. The system uses S3C6410 processor as the hardware foundation, mjpg,mediastream,Live555,VLC and other open source projects as the core, 3G mobile communication network as the network transmission medium, and H.264 encoding and decoding mode to realize the video acquisition, transmission and playback. And the integration of GPS module for position data acquisition, transmission, display, video monitoring, positioning of mobile targets. The front-end hardware of the system is compact and easy to use. The hardware of the system terminal is based on CPU of ARM11 architecture, and the software is designed with C language and shell script based on embedded Linux operating system. The backstage PC software integrates the functions of remote control, electronic map display and video display. C # and HTML language design. After the implementation of the system, the hardware codec MFC is added to improve the efficiency of H.264 coding, and according to the open source PHP Fetion interface, the function of sending short messages to control the remote terminal free of charge is completed. Different versions of the software have been developed according to different network environments, and a patent has been filed for the use of a new type of software. This system combines computer multimedia technology and mobile Internet technology organically. It can be applied to the specific business of various industries and can improve the informatization degree of business and the work efficiency of personnel. The design idea of this paper can be widely used in vehicle surveillance, wireless video surveillance and other fields, has a wide range of practical value and promotion significance.
