【摘要】：伴随着物联网技术的发展和宽带速率的提升,具备远程监控功能的IP摄像机产品在市场上得到应用普及。研发出一套B/S架构下以在线视频监控显示为核心的管理信息系统,将会极大满足很多矿山企业和政府监管部门的实际需求。如何在远程读取并播放IP摄像机传回的视频数据?如何让视频模块与管理信息系统协同工作?这将成为本文研究的重点。针对上述问题,结合矿山资源在线统一监控平台这一实际项目需求,进行相关研究和系统设计,论文主要工作包括以下几个方面：(1)研究在B/S架构下基于浮动窗口的在线视频显示方法,以EXT.NET中Window控件作为容器,将视频播放窗口放入其内,实现视频画面的浮动。(2)对视频监控模块的播放业务流程进行分析,以掌握从前端图像采集到后台正常播放的各种环节和步骤,利用大华公司提供的OCX二次开发包实现在线视频播放功能。(3)针对在线视频模块工作中遇到的网络延迟带来的登录缓慢问题,提出一种能够一次登录多次观看视频的方法。(4)将Google在线地图模块引入管理信息系统中,以实现与在线视频模块的无缝衔接。(5)基于上述研究基础,针对政府监管部门和企业所提需求,设计开发矿山资源在线统一监控平台。目前,该系统已经在某县的矿山资源在线统一监控平台中得到应用,系统运行正常、满足功能需求、实际效果良好。
[Abstract]:With the development of Internet of things technology and the improvement of broadband rate, IP camera products with remote monitoring function have been widely used in the market. A set of management information system based on online video surveillance and display under B / S architecture will be developed, which will greatly meet the actual needs of many mining enterprises and government regulators. How can I read and play video data from an IP camera remotely? How to make the video module and the management information system work together? This will be the focus of this paper. In view of the above problems, combined with the actual project demand of online unified monitoring platform of mine resources, relevant research and system design are carried out. The main work of this paper includes the following aspects: (1) the online video display method based on floating window under B / S architecture is studied. The window control in EXT.NET is used as the container to put the video playing window in it. To realize the floating of video picture. (2) analyze the business flow of video monitor module, in order to master the various links and steps from front-end image acquisition to background normal play, The OCX secondary development kit provided by Dahua Company is used to realize the online video playback function. (3) aiming at the slow logon problem caused by the network delay in the work of the online video module, This paper proposes a method to log in and watch video multiple times at a time. (4) the Google online map module is introduced into the management information system to realize the seamless connection with the online video module. (5) based on the above research foundation, According to the demand of government supervision department and enterprise, the online unified monitoring platform of mine resources is designed and developed. At present, the system has been applied in the unified online monitoring platform of mine resources in a county. The system is running normally and meets the functional requirements, and the actual effect is good.
