Research And Design Of Embedded Hydrology Information Acquisition Intelligent Terminal

The hydrology information modernization is foundation and guarantee which national economy can develop continuously, healthy and stably, the advanced hydrology information acquisition technology and the acquisition method are important component of hydrology information modernization, Therefore this article which propose to study and design the embedded hydrology information acquisition intelligent terminal, is for the purpose of studying and designing one kind of long-distance wireless hydrology information acquisition terminal which can acquire and control, and author applies it in DongYing Project hydrology information acquisition and control system.The embedded hydrology information acquisition intelligent terminal adopts present advanced embedded technology and GPRS wireless communication technology, it can acquire , save,inquire and transmit many kinds of hydrology information, and it can complete the control duty for strobe as flood discharge, dumps pollutants and drainage.The design of the embedded hydrology information acquisition terminal includes the hardware platform constructing and the system software development. The hardware platform constructing is the overall system foundation and difficulty, in this article it adopt mult-interface and high performance CPU S3C2410X based on ATM920T,it adopt also SIEMENS MC35i as communication module. The design of hardware include core board circuit , extension board circuit, data acquisition module circuit and GPRS module circuit. At the same time, it includes design and debugging of PCB. The system software includes development of driver, programming of communication program and GUI program. Author have completed program LCD driver, SPI driver and GPRS module driver, Author have completed design embedded GUI based on Qt/Embedded and some communication program.The embedded hydrology information acquisition intelligent terminal which this article study and design conform to hydrology information acquisition automatic , informatization request. The article has completed hardware design and part software programming, which has established the solid foundation for finally thrusting this system to the market and the widespread application.
