【摘要】：視頻監(jiān)控系統(tǒng)是一種防范能力較強(qiáng)的安全防范系統(tǒng)。視頻監(jiān)控以其直觀、方便、信息內(nèi)容豐富而廣泛應(yīng)用于金融系統(tǒng)、交通系統(tǒng)、公安系統(tǒng)、教育系統(tǒng)和醫(yī)療系統(tǒng)等眾多領(lǐng)域。近年來，隨著視頻監(jiān)控的普及，人們對(duì)視頻監(jiān)控畫面的清晰度要求越來越高，傳統(tǒng)標(biāo)清視頻監(jiān)控系統(tǒng)已不再適應(yīng)時(shí)代發(fā)展的需要，因此研究開發(fā)具有自主知識(shí)產(chǎn)權(quán)的高清視頻監(jiān)控系統(tǒng)，有著良好的市場(chǎng)前景。 基于嵌入式操作系統(tǒng)Linux2.6.31.8平臺(tái)，結(jié)合Marvell MV78100高性能處理器，設(shè)計(jì)實(shí)現(xiàn)了一個(gè)嵌入式高清視頻監(jiān)控系統(tǒng)。在硬件上，系統(tǒng)通過FPGA控制壓縮芯片將高清攝像機(jī)拍攝的高清視頻數(shù)據(jù)進(jìn)行壓縮，并選用了Marvell公司高性能處理器MV78100，通過該芯片上的Device Bus，實(shí)現(xiàn)了高清視頻數(shù)據(jù)的實(shí)時(shí)傳輸。在軟件上，系統(tǒng)移植了Linux2.6.31.8，并搭建嵌入式開發(fā)平臺(tái)，通過Linux下/dev/mem設(shè)備以及mmap系統(tǒng)調(diào)用實(shí)現(xiàn)了在用戶態(tài)下操作Device Bus，避開了嵌入式開發(fā)中驅(qū)動(dòng)編寫的環(huán)節(jié)，并保證了數(shù)據(jù)傳輸?shù)募皶r(shí)性與可靠性。 嵌入式高清視頻監(jiān)控系統(tǒng)解決了傳統(tǒng)視頻監(jiān)控系統(tǒng)畫面清晰度不高的問題，在不同使用環(huán)境下都有較好的效果，廣泛適用于金融系統(tǒng)、交通系統(tǒng)、公安系統(tǒng)和醫(yī)療系統(tǒng)等眾多領(lǐng)域。
[Abstract]:Video surveillance system is a kind of security system with strong ability of prevention.Video surveillance is widely used in many fields, such as financial system, transportation system, public security system, education system and medical system.In recent years, with the popularity of video surveillance, people have higher and higher requirements for the definition of video surveillance pictures. The traditional standard and clear video surveillance system has no longer adapted to the needs of the development of the times.Therefore, the research and development of high-definition video surveillance system with independent intellectual property rights has a good market prospect.Based on the embedded operating system Linux2.6.31.8 platform and Marvell MV78100 high performance processor, an embedded high-definition video surveillance system is designed and implemented.In hardware, the system uses FPGA to control the compression chip to compress the high-definition video data taken by the high-definition camera, and selects the high performance processor MV78100 of Marvell Company. Through the Device bus on the chip, the real-time transmission of high-definition video data is realized.In software, the system transplanted Linux 2.6.31.8and set up an embedded development platform, through the Linux / dev-mem device and mmap system call to realize the operation of Device in the user state, avoiding the link of driving programming in the embedded development.And ensure the timeliness and reliability of data transmission.The embedded high-definition video surveillance system solves the problem of low definition of the traditional video surveillance system. It has good effect in different use environments and is widely used in financial system and transportation system.Public security system and medical system and many other fields.
