现代农业节水灌溉管理系统的设计与开发

学 生：邹龙龙

专 业：计算机科学与技术

指导教师：邓蕾蕾

摘 要：随着经济的日益增长，信息化时代也悄然到来，生活中各种各样的信息趋向于数字化和清晰化。节水灌溉管理系统就是在这样的一个环境中诞生的，我国对农业重视程度越来越高，农业种植在空间上越来越趋向集中化，在时间上越来越趋向四季化，因此，大面积的大棚种植出现，因此我们将发挥计算机的庞大的存储空间，高性能的处理能力，清晰的可视化数据等这些优势来实现农业对节水灌溉的要求，实现了计算机资源的合理利用，真正实现了减少劳动力提高劳动质量的目的。本文主要分析了系统的主要组成情况，包括需求情况，系统的设计目标，数据结构，数据流程和系统的主要特点等，重点介绍了系统功能模块的详细思路和实现方法，以及对系统关键技术和部分源代码的详细说明。

The design and development of modern agriculture water-saving

irrigation management systems

Name：Zou Longlong

Major：Computer science and technology

Tutor：Deng Leilei

Abstract：Along with economic increase increasingly, the information ages has come quietly, every kind of information in the life incline to the arithmetic figure turns and clear turn. Water-saving irrigation management system is to bear in such an circumstance exactly. Our county have pay more and more attention to agriculture, agricultural cultivate is being concentrate in space, and tend to all the year around in time, hence, large tracts of land trellis-planting emerged. Therefore we will develop the huge and saving space of the calculator, the high performance handles ability, high dependable data safety, clear see to turn the data wait these advantages to help realize the demand of agricultural water-saving irritation, realizes the reasonable exploitation of the calculator resources, real realizes the decrease labor force increases the purpose of the labor quantity. This text analyzes the system primarily to constitute primarily, including need analysis, the design target of the system, data construction, data flow chart with main characteristics etc. of the system, the point introduces the detailed way of thinking of the system function mold and realizes method, and elaborate …… 此处隐藏：3009字，全部文档内容请下载后查看。喜欢就下载吧 ……
