Internet Of Mobile Video Surveillance System Research And Design

With the rapid development of Internet of things moving,the continuous improvement of the embedded technology,image processing was became more and more mature,processing and application of the video data,video surveillance equipment market demand are provided the necessary conditions for the development of video surveillance.Embedded microcontroller processor to improve the performance of good combined with the real-time video surveillance market demand,through the network transmission of real-time effects.Designed according to the requirements of real-time video surveillance solutions,from hardware design,system build,driven design,software design,by using the high performance processing Cortex-A8,USB video data acquisition,compression,data transmission network,Eventually reach the Internet of things under the architecture of mobile monitoring system requirements.This paper introduces development and research status of the video surveillance system;Then introduces the Internet of mobile video surveillance hardware platform design,the design scheme of the hardware schematic diagram adopted core plate and bottom plate separate design patterns,this paper introduces the Cortex-A8 S5PV210 performance as well as the core of the processing as the core board,designed a power supply circuit,Nand Flash circuit,etc.,such as USB,SD card designed for floor slab schematic diagram;Analyzed the architecture of embedded Linux development environment,software environment,build good system need Linux cross compile environment,guided system is introduced and write,kernel transplantation,etc;Through the mobile video surveillance and its related driven development,such as design TVP5150 drives,V4L2 camera driver simple Linux device driver is introduced at the same time;Introduces the system,acquisition module programming,network transmission module program,video decoding module procedures,finally tested system as a whole.This paper implements the Internet of things the USB data collection,mobile video compression coding,transmission are realized by web to mobile,according to the client and the local have larger significance,video monitoring of the Cortex-A8 research has certain reference value.
