【摘要】：在網(wǎng)絡(luò)技術(shù)快速發(fā)展的今天,網(wǎng)絡(luò)視頻數(shù)據(jù)的產(chǎn)生、傳輸和存儲的要求也越來越高。同時,視頻監(jiān)控的使用范圍逐漸深入到人們生活的各個方面,大數(shù)據(jù)量高清視頻成為安全生活的必不可少的一部分。利用互聯(lián)網(wǎng)來組織和利用視頻數(shù)據(jù)是一個很有效的方式。 本文以基于網(wǎng)絡(luò)的視頻監(jiān)控為研究對象,提出并設(shè)計了一種基于IP網(wǎng)絡(luò)的視頻存儲系統(tǒng)的解決方案,將視頻的存儲透明化,并通過管理平臺的管理使視頻存儲管理虛擬化,系統(tǒng)可以在可接受的時間內(nèi)提供用戶的基本服務(wù),同時能適應(yīng)最終存儲系統(tǒng)海量存取的需求。主要工作如下： 1、首先從存儲系統(tǒng)的需求入手,分析了存儲系統(tǒng)的功能、性能需求,并完成邏輯功能和數(shù)據(jù)庫設(shè)計,主要基于用戶對視頻的錄制、查詢、回放等功能實現(xiàn)了視頻數(shù)據(jù)的存儲機制設(shè)計,保證服務(wù)管理平臺和存儲系統(tǒng)的穩(wěn)定性。 2、為了實現(xiàn)管理和存儲的用戶透明化,設(shè)計了管理平臺和存儲系統(tǒng)的虛擬化,以實現(xiàn)存儲系統(tǒng)的穩(wěn)定性。管理平臺和存儲系統(tǒng)都不是一個單獨的PC機和服務(wù)器,為了防災(zāi),將它們做成集群的方式,管理平臺為每一個存儲節(jié)點分配一個IP,將存儲節(jié)點虛擬化,客戶關(guān)心的數(shù)據(jù)會被存儲到存儲系統(tǒng)中的某一個節(jié)點,但不需要關(guān)心自己的數(shù)據(jù)具體存儲在什么地方,而重點關(guān)注數(shù)據(jù)是否安全、是否能夠容災(zāi)、數(shù)據(jù)的存取是否方便方面。 3、進(jìn)行了存儲管理系統(tǒng)的整體設(shè)計。存儲系統(tǒng)可以接收和產(chǎn)生一些命令,反應(yīng)了客戶端或者管理平臺期望的服務(wù),首先對系統(tǒng)虛擬化進(jìn)行了詳細(xì)設(shè)計,然后就網(wǎng)絡(luò)視頻監(jiān)控系統(tǒng)的各子系統(tǒng)的關(guān)系和組成部分、系統(tǒng)數(shù)據(jù)庫設(shè)計有了明確闡述,進(jìn)而分析了存儲管理基于命令收發(fā)、處理、回話、數(shù)據(jù)存儲、內(nèi)存管理、狀態(tài)維護(hù)等方面的詳細(xì)設(shè)計方案,重點研究了線程對會話管理和數(shù)據(jù)收發(fā)的實現(xiàn)。 4、完成了存儲管理系統(tǒng)運行方案的實現(xiàn)。重點從存儲系統(tǒng)虛擬化方面介紹了管理平臺對IP的分配和同步以及存儲節(jié)點獲取IP的方式,同時就系統(tǒng)存儲功能和狀態(tài)維護(hù)的實現(xiàn)展開說明,主要涉及到監(jiān)聽模塊、錄像池、心跳／負(fù)載上報、錄像卷操作、系統(tǒng)初始化、負(fù)載／循環(huán)覆蓋周期上報、系統(tǒng)功能模塊等。 本文研究并基于設(shè)計實現(xiàn)的監(jiān)控系統(tǒng)在投入使用過程中運行狀況良好。
[Abstract]:With the rapid development of network technology, the requirements for the generation, transmission and storage of network video data are increasingly high. At the same time, the use of video surveillance has gradually penetrated into all aspects of people's lives. High-definition video with large amount of data becomes an essential part of safe life. It is an effective way to organize and utilize video data using the Internet. In this paper, a solution of video storage system based on IP network is proposed and designed, which can make video storage transparent and virtualize video storage management through the management of management platform. The system can provide users' basic services within an acceptable time and can meet the requirements of mass access of the final storage system. The main work is as follows:. 1. Starting with the requirements of the storage system, the function and performance requirements of the storage system are analyzed, and the logic function and database design are completed, mainly based on the recording and querying of the video by the user. The function of playback realizes the design of storage mechanism of video data and ensures the stability of service management platform and storage system. 2. In order to realize the user transparency of management and storage, the virtualization of management platform and storage system is designed to realize the stability of storage system. The management platform and storage system are not a single PC and server. By clustering them, the management platform assigns an IPs for each storage node, virtualizes the storage node, and the data that the customer cares about is stored to a node in the storage system. But we don't need to pay attention to where our data is stored, but focus on whether the data is safe, disaster tolerant and easy to access. 3. The whole design of storage management system is carried out. The storage system can receive and produce some commands, which reflect the expected services of the client or management platform. Firstly, the system virtualization is designed in detail. Then, the relation and component of each subsystem of the network video surveillance system, the database design of the system is expounded clearly, and then the storage management is analyzed based on the command sending and receiving, processing, reply, data storage, memory management, etc. The implementation of session management and data sending and receiving by thread is studied in detail. 4. The implementation of the storage management system is completed. From the aspect of storage system virtualization, the distribution and synchronization of IP in the management platform and the way for the storage node to obtain IP are introduced. At the same time, the realization of system storage function and state maintenance is explained, which mainly involves monitoring module, video pool, heartbeat / load report, video volume operation, system initialization, load / cycle coverage cycle reporting, system function module and so on. In this paper, the monitoring system based on design and implementation is running well in the process of operation.
