【摘要】 水文资料在水利行业中起着非常重要的作用,在我国西部地区水文数据传输方面与发达国家相比还有较明显的差距。寻求一种经济、快速、稳定、可靠的水文信息传输系统是我国西部水文采集工作的当务之急。通过对基于51单片机的GPRS水文数据无线传输系统的软件和硬件设计,提出了硬件设计简单、投资经济、运行维护方便的小型GPRS水文信息采集系统方案,为西部地区积累丰富、详实的水文资料提供了有力保障。更多还原

【Abstract】 The hydrologic data is playing very important role in water conservancy industry,but our country still has the comparatively obvious gap in the field of hydrological data transmission with the developed countries.It is urgent to find out an economic,fast,stable,reliable hydrologic information transmission system for our western region.Through software and hardware design of GPRS hydrologic data wireless transmission system based 51 MCU,this paper puts forward a mini-type GPRS hydrological information acquisition with simple hardware design,investment economy,easy operation and maintenance,which can provide a strong safeguard for accumulating full and accurate hydrologic data.更多还原
