Video Surveillance System Is Based On Tower Crane

In recent years,with the rapid city construction development, more and more high-rise buildings spring up all over our city, so the frequency of use of tower crane,which mainly used to improve the speed of construction and ensure the construction quality and reduce the labor intensity of workers, are also constantly improving in the construction process. Since complicated working environment,technicians have to consider to the question how to carry on secure and efficient construction work in the construction process.One of the most prominent is the visual problems encountered in site construction of high-rise, such as lifting, unloading, mobile building materials in the tower crane, the building body may block the sight line of operators, the operating personnel from the glare zone moves to the dark zone, in the strong contrast of light under the operation personnel, can not see the specific operation process, and then they can only rely on the experience and blind operation.Aiming at the problem of blind operation in construction,this paper designed a set of applied in video surveillance system of tower crane for he operating personnel to increase visual auxiliary function.In order to facilitate the specific operation personnel can carry out construction operation according to specific site conditions, the system needs to install the camera in the tower crane boom to monitor the specific construction site, camera video acquired by signal after through a series of processing, and then signal by wireless transmissionequipment WIFI transmit into operating room control terminal on the top of tower crane, the design of the video monitoring system has brought great convenience for the operating personnel according to the conditions of the specific operation.This system design a video acquisition, transmission, coding and display and a series of function modules and so on.Hardware device used S3C2440 hardware platform combined with PC and operating system software adopted embedded Linux systems,In order to clearly state the main point of this article, the following will be divided into five chapters.The first chapter is the introduction, the purpose of topic background and research significance, video monitoring system applied to tower crane on the research status and development trend at home and abroad, this chapter will be mainly introduced the paper main research work and the specific chapters arrangement;The second chapter mainly introduces the design of the overall scheme of video monitoring system, this chapter mainly comprises two parts, respectively, the design of hardware and software;The third chapter mainly introduces the construction of the video monitoring system of the underlying software platform, in this part will finish on the host machine to establish the embedded Linux systems cross compile environment and QT development environments, transplantation system bootstrap uboo on the development platform,system kernel Linux2.6.32 and root file system of production;The fourth chapter is the design and implementation application of video monitoring system, mainly complete the camera driver and video capture application, call the MJPEG compression algorithm for video data compression, wireless network card driver programming, based on the TCP protocol Socket network programming to realize network video data information transmission, using of client program Watch the video;The fifth chapter is the conclusion and prospect part, summarized the work of the paper, and then put forward the further improvement measures.
