[Abstract]:Video surveillance has always been one of the hotspots of application technology. Video surveillance system has been widely used in various fields, such as intuitive, convenient, rich content and so on. With the rapid development of image coding and decoding technology, embedded technology and network technology, video surveillance has moved from digital video surveillance to the era of embedded network video surveillance. The advanced performance of network video surveillance technology makes it have a huge potential market and considerable economic benefits. This paper applies the embedded network video surveillance system to the field of disaster rescue robot. The system has two core functions: one is video image acquisition and compression coding, the other is video data transmission. The video surveillance system of disaster rescue robot is mainly divided into three parts: the front end of video monitoring for disaster rescue robot, the vehicle center control storage server and the monitoring end. The structure of this paper is as follows. First of all, this paper discusses the development of disaster rescue robot, analyzes and compares the existing network video surveillance technology, synthesizes the advantages of various technologies. Based on arm and embedded Linux, a high reliability B / S architecture disaster rescue robot video surveillance system is designed. The main function of the system is to collect, compress and encode the video data and transmit it wireless, and realize the video monitoring on the monitor end through the browser. Then the whole system is described in detail. In the aspect of hardware, the core hardware platform of this system includes TMS320DM365 digital signal processor of Texas Instruments (which integrates arm kernel and DSP), camera, etc. The front-end of the video surveillance system of disaster rescue robot is constituted by the development board of on-board central control storage server and monitoring terminal .TMS320DM365 and the camera. The video image is compressed and encoded and transmitted by the video image acquisition board of TMS320DM365, which is used to collect the video image by the camera. The on-board central control storage server can receive the image data transmitted by the disaster rescue robot video surveillance front-end, store and provide access rights to the monitoring terminal, and the monitoring end mainly realizes the access to the on-board central control storage server. Play video picture and alarm. In the software aspect, after analyzing various software architectures, the system chooses the B / S architecture. In addition, the network transmission protocol is defined as the RTP commonly used in streaming media, which realizes the real-time transmission of video data on wireless network, and ensures the quality of video transmission at the same time. Finally, the security of the video surveillance system of the disaster rescue robot is analyzed, including the security of the operating system and the security countermeasures when it is applied in the network environment.
