基于ARM单片机的水情采集器设计

本文结合灌区水情测报的实际情况,论述了水情测报网络的设计,采用ARM单片机S3C44B0X设计前端水情采集器,给出硬件设计原理和实现方案,阐述灌区水情测量原理,为提高数据的可靠性,采用格雷码作为输出码,采用水位-流量曲线法,根据水位进行换算测得流量,软件设计采用C语言编程,实现灌区水位和流量的测量,数据的处理和存储,测量结果的输出与显示等功能.调试结果表明,这种设计方案能够满足实际应用的需要.

Design of Water-Condition Collector Based on ARM Single-chip Microcomputer

The design of network for water-condition measuring was introduced in the paper, combined with the fact of water-condition measuring in irrigation districts, The water-condition collection instrument was designed with ARM single-chip microcomputer S3C44BOX, whose hardware principle and the realizing-scheme were put forward. To enhance the reliability of data transaction, the paper took Gerry code as output code, and took water lev- el-flux curve to measure flux with water level, and introduced the water-condition measuring principle in irrigation districts. The paper used C language to design software to realize the measurement of water level and flux, dealing and store of data, output and display of the measurement. The result shows that the scheme is able to need of the practical application.
