【摘要】：隨著人民生活水平的提高,對可視范圍的需求不斷增大,人們越來越希望“看”到世界。傳統(tǒng)的監(jiān)控大多還采用有線傳輸,高昂的成本、監(jiān)控地點的局限性使其應(yīng)用受到了極大的限制。傳統(tǒng)的無線接入方式則存在著建設(shè)復(fù)雜、工期長、成本高等問題。隨著嵌入式技術(shù)的快速發(fā)展和我國3G網(wǎng)絡(luò)的大規(guī)模建設(shè)和商用,智能圖像監(jiān)控和入侵報警系統(tǒng)的穩(wěn)定性及網(wǎng)絡(luò)傳輸速度都得到了很大的提高,并且其低功耗、體積小的特點,使系統(tǒng)逐漸擺脫了時間、空間的限制,達到遠程無人值守監(jiān)控的目的。 本文研究實現(xiàn)了基于3G網(wǎng)絡(luò)的遠程無人值守圖像記錄報警系統(tǒng)。完成了基于ARM的嵌入式硬件平臺的構(gòu)建、嵌入式Windows CE系統(tǒng)的定制,并詳細(xì)闡述了監(jiān)控終端和服務(wù)器的相關(guān)的理論依據(jù)及基于.NET的軟件設(shè)計。結(jié)合服務(wù)器、管理終端、監(jiān)控終端完成了對現(xiàn)場布防、報警、圖像壓縮傳輸?shù)裙δ堋?為構(gòu)建該系統(tǒng)的基礎(chǔ)設(shè)施,重點要解決的問題是信息如何在分布式系統(tǒng)中傳遞和如何控制不同計算機之間的協(xié)作。提出了“簡單信息傳遞協(xié)議”和“狀態(tài)機”解決這兩個問題。簡單信息傳遞協(xié)議可以控制數(shù)據(jù)的流向和信息的存在形式,將所有信息以統(tǒng)一的方式進行傳輸,使協(xié)議的適用性更為廣泛。狀態(tài)機的應(yīng)用使各模塊協(xié)作更加緊密,配合網(wǎng)絡(luò)模塊,可以實現(xiàn)分布式計算。
[Abstract]:With the improvement of people's living standard and the increasing demand for visual range, people want to see the world more and more. The traditional monitoring is mostly wired transmission, high cost, the limitation of monitoring location makes its application greatly limited. The traditional wireless access mode has many problems, such as complex construction, long construction period and high cost. With the rapid development of embedded technology and large-scale construction and commercial use of 3G network in China, the stability and network transmission speed of intelligent image monitoring and intrusion alarm system have been greatly improved, and its characteristics of low power consumption and small volume. The system gradually gets rid of the limitation of time and space to achieve the purpose of remote unattended monitoring. The remote unattended image recording and alarm system based on 3G network is studied in this paper. The construction of embedded hardware platform based on ARM and the customization of embedded Windows CE system are completed. The theoretical basis of monitoring terminal and server and the software design based on .NET are described in detail. Combined with the server, management terminal, monitoring terminal to complete the scene defense, alarm, image compression transmission and other functions. In order to build the infrastructure of the system, the key problem to be solved is how to transfer information in distributed systems and how to control the cooperation between different computers. A simple information transfer protocol and a state machine are proposed to solve these two problems. Simple information transfer protocol can control the flow of data and the existence of information, and transfer all information in a unified way, making the protocol more widely applicable. The application of state machine makes each module cooperate more closely, cooperate with network module, can realize distributed computing.
