Abstract

One kind based on embedded Internet, uses DSP and the ARM independent binuclear structure river sediment image system. In the video frequency track, uses Kalman filter algorithm which has the forecast function, designed one kind advanced version PID controller which has the robust, compress code by the DSP system to the information, then transmit the image coding to the ARM system, the ARM system the pack the compression code through the network protocol stack, then transmission through gateway according to demand. This system can record river sediment flow situation, image information and correlation environmental information synchronizations and so on in real-time, and can saved and preserved.
