【摘要】：我国水资源严重短缺,一些地区地下水位连年下降。通过将控制和管理相结合,规范农业灌溉用水水价收费制度,引导农业灌溉科学用水、节约用水,逐步实现精准灌溉是农业现代化的一个必然发展方向。本文把RFID技术及GPRS技术相结合运用到智能灌溉领域,开发了农业灌溉控制终端机,实现灌溉用水的计算机远程计量、控制和管理功能。为农业生产现代化、信息化提供一种技术支持,同时可为实现农业精准灌溉提供信息依据。本文主要研究工作:1、在深入调研农业灌溉用水现状、用水的管理方式及需求的基础上,设计了智能灌溉终端机的整体技术方案,并对主芯片、GPRS芯片、流量计、读卡器等主要器件进行了选型。2、设计了以单片机为核心,包括智能灌溉终端机主控板的电源模块、读卡模块、GPRS数据传输模块等的终端机电路。3、根据智能灌溉终端机的功能要求及操作流程,设计了读写卡、水费计量、GPRS信息传输、信息管理与用水控制等应用软件。4、对主芯片进行了嵌入式实时操作系统UCOS-Ⅱ的移植,在UCOS-Ⅱ系统中对各任务进行了软件编程。5、开发了终端机的实验样机,对所设计的硬件、软件进行了调试及功能测试,测试结果表明了主要功能完全满足设计要求。
[Abstract]:There is a serious shortage of water resources in our country, and the groundwater level in some areas has dropped year after year. By combining control and management, we should standardize the system of water pricing for agricultural irrigation water, guide the scientific use of water for agricultural irrigation, and save water. It is an inevitable development direction of agricultural modernization to realize precision irrigation step by step. This paper applies RFID technology and GPRS technology to intelligent irrigation field, develops agricultural irrigation control terminal, realizes the computer remote measurement of irrigation water. The function of control and management provides a kind of technical support for the modernization of agricultural production and informationization, and can also provide information basis for the realization of precision irrigation in agriculture. Based on the management mode and requirement of water, the whole technical scheme of intelligent irrigation terminal is designed, and the main chip, GPRS chip, flow meter, card reader and other main devices are selected. It includes the power supply module of the main control board of intelligent irrigation terminal, the terminal circuit of GPRS data transmission module of card reading module, etc. According to the function requirement and operation flow of intelligent irrigation terminal, a read-write card and GPRS information transmission are designed. The main chip is transplanted to the embedded real-time operating system UCOS- 鈪，
