基于无线网络实时视频传输及管理系统研究
摘要
随着相关建设工程监理法规的建立,建设工程监理在保证建设工程质量和使用安全方面起着越来越重要的作用。利用计算机、网络技术实现监理信息化,可以提高监理水平、丰富监理手段。
流媒体技术在上世纪末开始渐渐成为了计算机应用领域的一个热门研究方向,无线网络技术也随着硬件技术的发展而日趋完善。基于无线网络的视频传输作为上述两种技术的交叉研究方向,在各种实际应用领域中具有很广泛的应用需求,具有很高的研究价值。
为了提高监理的信息化程度,本文提出了一个基于无线网络的视频传输和管理系统。该系统是利用流媒体技术和无线网络技术来构建的。
系统的主要功能有三项:实时监视、远程指导和多媒体信息管理。实时监视功能,就是将施工现场采集的视频信号通过网络传送到远程的监视地点,实现对施工现场施工状况的异地监视。远程指导功能,就是当施工现场出现不能解决的监理问题时,通过该功能,现场监理人员可以与身在异地的专家进行交流,得到他们的指导和建议,解决现场出现的问题。多媒体信息的管理功能,主要是实现对从施工现场采集的视频和图片的管理和应用。
整个系统由实时子系统和非实时子系统两个部分组成。实时子系统采用C/S架构实现,服务器端是一个应用服务器(App Server);客户端有三种类型:Center、Expert和Supervision,功能各不相同。他们通过传递消息,相互之间协同工作,共同组成一个有机的整体,完成系统的远程监视和指导功能。非实时子系统采用B/S架构实现,完成系统的最后一项功能。
通过该系统,监理单位可以建立一个不受施工地域限制、可以统观全局、同时对多个施工现场、每个施工现场多个视角进行远程监控和指导的施工监理中心。从而提高监理的信息化水平,丰富了监理的手段。
With the establishment of laws related to it, the supervision of construction project plays an increasingly important role in the area of ensuring the quality and safety of construction projects. Making use of the computer technology and network technology to carry out supervision information-based, we can’t only raise supervising level, but also enrich supervising means.
Streaming Media Technology gradually became a hot research field of computer application at the end of the 20th century. Wireless network technology is becoming better and better with the development of hardware technology. As a cross-cutting research direction of these two technologies, Video transmission on the wireless network has a very broad application needs in various areas of practical application and has a very high research value.
In order to improve the level of supervision information-based, in this paper, the writer raises a wireless network based video transmission and management system. It uses streaming media technology and wireless network technology building.
The system has three main functions. First, real-time monitoring, and second, long-range guidance, and the third is multimedia information management. Use real-time monitoring function, the video signal which is captured on construction site can be sent to the remote monitoring site through Internet. When supervisors can not solve the problems encountered at the construction site, they can exchange views with other experts, and under the guidance of experts to address the issue by using long-range guidance function. Through multimedia information management function, we can manage and take use of video and picture which were transmitted from construction site.
The entire system consists of two subsystems. One is real time subsystem, and the other is non-real time subsystem. The real time section adopts the frame of C/S, the server is an application server; and there are three types of client, one is“Center”, the other is“Expert”, and the last is“Supervision”, they function are different. They work together to form an organic whole by transmitting information between each other. So they can achieve the long-range surveillance and guidance functions. The non-real time section adopts the frame of B/S, it achieves the last function of the system.
Through the system, the supervision company can build an information-based center of construction supervision by which can raise supervising level and enrich supervising means.
