Research And Implementation Of Video Monitoring System Based On4G Network

In recent years, with the rapid development of electronic technology and communication technology, Video surveillance technology gets rapid development. Video surveillance technology has been widely used in many fields, such as city management, security, traffic control. In these fields it plays an irreplaceable role.This paper studies the design and implement of a front-end device using4G network under a Large and widely distributed circumstances. Firstly this design explores the development course, research background and the development trend of surveillance technology, then it elaborates the system design and the realization process in detail, after that discusses the process of design and implement of video surveillance system using4G network from hardware and software aspects. Finally, summarizes the research achievements of the design and analysis the deficiencies in the existing design.The main work in this paper include the following aspects:(1) States the development of video surveillance technology and the feasibility of4G network video surveillance system.(2) Elaborates design principles and the overall design scheme, the front-end equipment design ideas, software design of the video surveillance system.(3) Discusses the hardware design of the front-end video monitoring and describes the specific hardware design of the four big modules respectively.(4) Elaborates the design of a front-end device video surveillance system based on4G network, which has the porting bootloader, operating system kernel transplantation, the root file system of the transplant and the wireless network card driver transplantation, further more designs the application software of the transmission part.(5) Introduces the case of practical application of4G network video surveillance system, also reviews the hot topics and insufficiencies of this study.Traditional video surveillance system is difficult to expand, costs a lot, also has the same higher maintenance cost due to limited by transmission cable. After the completion it is unable to carry on the monitoring to mobile equipment vehicle etc. This video surveillance system based on4G network by using the new4G network, broking the transmiting restriction, greatly improving the scope of application, and effectively reducing the cost of network video surveillance system and maintenance cost. It not only can effectively deal with the new demand of security monitoring by further expanding and developing, but also can be used for temperature, humidity, strain and other special monitoring field. Above all it has positive significance to the construction of information society.
