An independent dual-core structure of the river sediment of image data transmission system

An independent dual-core structure of river sediment image data transmission system based on DSP and ARM, it uses dual audio frequency signals to transmit, and adopts Kalman filter algorithm with prediction function, it also has improved robustness PID controller. The system compress codes through DSP system then transmit good-dealt image codes to ARM system, the ARM system would pack the compress codes from DSP through network protocol, and send as demand through network gateway. This system has solved the interference produced by wireless wave of cable support and environment around during transmission, which could influence the test work, or even unable do it. This system put embedded technology, video technology and network technology together organically. It has many features, such as reliability data transmission, use easily, convenient and so on. It also can provide an advanced hydrological detective method for image detect river segment research.
