针对水文数据采集点地理位置分散的特点,提出了一种基于GPRS无线通信的地面低功耗水文采集终端的设计方案,介绍了该采集终端的硬件电路和软件的设计。实现了水文信息的长时间采集、处理、存储和传输。实验结果表明,该采集终端通信可靠,省电耐用,实时性强,实现了低成本高效率的结合。
Aiming at the geographical dispersion of hydrological data collection points, a design scheme of ground low power hydrological acquisition terminal based on GPRS wireless communication is proposed. The hardware circuit and software design of the acquisition terminal are introduced. A long time to achieve the hydrological information collection, processing, storage and transmission. The experimental results show that the acquisition terminal communication is reliable, power-saving and durable, real-time, achieving a combination of low cost and high efficiency.
