Because the society progress unremittingly, the economy develops quickly with technique to advance by leaps and bounds, public order safety, produce a safety, property safety etc thus make take the video frequency information as the supervision system of the characteristic more broadly drive apply in each profession realm. Supervise and control the technique has already developed as the third generation, but still existed in the technique problem of several keys, limited supervision system development. Along with built-in progress unremittingly technically, the wireless data delivers speed raised continuously, emerging with the tide of the times according to the wireless supervision system of the built-in terminal.Aim at the irregularity of the tradition supervision system, analyzed the network structure of "wireless supervision system" of Radrort company in Shenzhen first, the hardware constitute and the software configuring, and with this background, put forward the solution of the network supervision terminal. There are 2 key problems resolved in the built-in terminal design, and the hardware and software principle design have completed.In consideration of the function index sign of the built-in terminal, after consider the cost and moderate breezes insurance of the hardware platform development, analysis 3 kinds of mature terminal solutions, make sure according to the ARM(IXP425)+DSP(DM642) built-in hardware total design. And completion the hardware platform total design, the hardware designs in detail and the signal cycle time analyze and logic of the work, etc.In consideration of the cost and the drive development difficulty of system terminal, making sure Linux as the operate system of the platform. On this foundation, analyzed the development process of equipments drive in the Linux environment, and introduced the CPLD driver development in detail under the Linux system. The theories basis for the DSP software code development is provided.At last, for verifying supervision terminal function and the playing result, the terminal work first, two pedestal terminals, customer's client and server to constitute the minimum of wireless network supervision system are used in this dissertation. Through the contrast verification, the supervision terminal of this text design comes to the design request completely, can satisfy an expectation of need. The key technique sign obvious advantage with contrast the same kind product.
