【摘要】:網(wǎng)絡(luò)視頻監(jiān)控系統(tǒng)結(jié)合了現(xiàn)在擁有的Internet和嵌入式兩大技術(shù)的優(yōu)點(diǎn),打破了傳統(tǒng)的視頻監(jiān)控系統(tǒng),不僅可以傳輸圖像和文字,視頻和音頻也可以同時(shí)傳送,實(shí)現(xiàn)了多媒體功能,因此在各種行業(yè)、單位都有廣泛應(yīng)用。云臺(tái)控制監(jiān)控?cái)z像頭已經(jīng)是現(xiàn)在的又一主流,隨著科技的不斷的發(fā)展進(jìn)步,視頻監(jiān)控將會(huì)向著高清化、智能化、專業(yè)化的方向發(fā)展。 本文針對(duì)gec2410進(jìn)行了網(wǎng)絡(luò)視頻監(jiān)控系統(tǒng)和云臺(tái)控制系統(tǒng)結(jié)合的設(shè)計(jì)與研究,既可以滿足遠(yuǎn)程圖像傳輸,,又?jǐn)U大了攝像頭的監(jiān)控范圍。 本文詳細(xì)介紹了gec2410開發(fā)板的硬件結(jié)構(gòu)組成,闡述了整個(gè)云臺(tái)控制網(wǎng)絡(luò)視頻監(jiān)控系統(tǒng)的工作原理,總體設(shè)計(jì)等內(nèi)容;谔摂M機(jī)實(shí)現(xiàn)了開發(fā)板linux操作系統(tǒng)的建立和系統(tǒng)文件移植,網(wǎng)卡、usb攝像頭驅(qū)動(dòng)載入,boa服務(wù)器移植等,設(shè)計(jì)了云臺(tái)控制模塊,描述了其工作原理,并且利用匯編語言實(shí)現(xiàn)了步進(jìn)電機(jī)的方向控制等。 通過實(shí)驗(yàn),最終可以獲得采集到的圖像,由于攝像頭的自身原因,清晰度有點(diǎn)低。通過調(diào)整脈沖的間隔和電機(jī)的驅(qū)動(dòng)方式,結(jié)合各項(xiàng)性能指標(biāo)的標(biāo)準(zhǔn),可以使得云臺(tái)的步進(jìn)電機(jī)穩(wěn)定工作,速度和精度可以有效的確定。
[Abstract]:The network video surveillance system combines the advantages of Internet and embedded technology, and breaks the traditional video surveillance system. It can not only transmit image and text, but also transmit video and audio simultaneously. Therefore, in various industries, the unit has a wide range of applications. With the development of science and technology, video surveillance will develop to the direction of high definition, intelligence and specialization. This paper designs and researches the combination of network video surveillance system and cloud head control system for gec2410, which can not only meet the remote image transmission, but also expand the surveillance range of the camera. In this paper, the hardware structure of gec2410 development board is introduced in detail, and the working principle and overall design of the video surveillance system for the whole cloud head control network are expounded. Based on the virtual machine, the establishment of the linux operating system and the migration of the system files are realized, and the network card USB camera is used to load the boa server and so on. The control module of the cloud head is designed, and the working principle of the module is described. The direction control of step motor is realized by assembly language. Through the experiment, the captured image can be obtained, because of the camera itself, the definition is a little low. By adjusting the interval of the pulse and the driving mode of the motor combined with the standards of various performance indexes the stepping motor of the cloud head can work stably and the speed and precision can be determined effectively.
