Research And Implementation On Wireless Monitoring And Control Software Of Internet Of Things

With the rapid development of embedded technology, network technology and wireless communication technology, The use of3G wireless networks transmit video images embedded video monitoring system has become the development trend of future surveillance industry.The paper rely on the Linux of embedded systems, use Hi3515chip,achieved a3G wireless video surveillance system. By3G wireless, the video stream is transmitted to the client after H.264encoded. Client can get real-time monitoring of video images. The paper mainly analyze the H.264video coding,3G wireless video transmission and dynamic stream, so that client can get high quality video images.The research includes:(1) In research of the traditional analog video surveillance, DVR and the algorithm of encoding compression. Combined with the current3G wireless network technology and Linux Embedded System Technology, use Hi3515video processing chip completed the transmission of video images by3G wireless network.(2) Proposed an application design of use3G wireless network video surveillance system in the embedded Linux operating system. With ARM and DSP Hi3515hardware platform, use Linux2.6.32kernel version of the operating system, using3G wireless network, transmiss the captured video image over a wireless network.(3) According to the design, the paper finally realized the monitor terminal Linux system, complete video capture, compression, transmission and coding3G wireless network function, the system was originally designed to achieve the purpose.The system testing showed that embedded3G video monitoring system designed in this paper can be through real-time video monitoring, system security, stability, easy to maintain, has a good practical value.
