Based On Arm Hydrological Sediment Image Data Sampling System Research

China has a vast territory and large water system, due to natural geographical conditions and the impact of the monsoon, floods, and droughts occurred frequently. Since ancient times, water conservancy project in the national economy plays an important role. The hydrological work as the basis for water conservancy, its role is undisputable; it involves the water conservancy work and many economic social aspects.The issue stems from the Hydrological Bureau of Ji'an the crosswise cooperation issues. This paper analyzed the results of research on their predecessors, combined advanced embedded technology, power line carrier, dual audio communications,etc. effectively, proposed an embedded design of hydrological sediment image data sampling systems. In the console using ARM9 S3C2410A, using its own keyboard and the LCD controller, can display and input the control information, completely out of the PC restrictions; use dual audio communication for the first time, achieve the data transmission between console side of the underwater side, has solved the instability of original hydrological data collection system in controlling; improve the existing flow and sediment measurement methods, improve the measurement accuracy.The system mainly uses embedded processor S3C2410A, double audio frequency send/receive chip MT5087/MT8870 as the hardware platform, VC++.NET as a software design platform. The article focused on the study:①Desinging underwater image acquisition device ;②Research and implementation of control valve;The system developed in the ADS and VC++.NET software platform and realized in hardware, after the consummation achieved the anticipated effect, for the finally sediment concentration research by image method has established a solid foundation...
