【摘要】：在中国农作物生育期内,因为降水量较少,河流和其它水资源缺乏,使得土壤的含水量降比较低,农作物在某一生长时期的所需水量小于所提供的水量,破坏了作物正常的生长,影响到了人们的生产和生活。精准农业是我国农业的发展方向,如果想建立一个符合中国国情的精准农业系统,必须要建一个适用于精准农业的信息管理模式。为了使农业抗旱水平增加,动态的了解土地旱情变化,缩小旱灾带来的损失,建立广泛覆盖的土壤墒情监测体系已经成为相应农业部门的重要任务之一。本课题研究的就是关于精准农业的一种形式:土壤商情数据无线监测系统。墒情一般是指土壤水分条件。墒情是作物种子出苗、生长和产量形成的重要条件之一。经常关注农田墒情及其改变,可为实时农业采取灌溉或排水形式提供有科学的依据。本文所设计的土壤墒情监测系统,主要完成了墒情监测站的硬件设计部分和软件设计部分,硬件部分主要是对所选用的单片机,传感器,以及GPRS模块进行了详细的分析和介绍以及对监测系统的整体电路图进行分析。软件部分主要是进行了墒情采集的一系列程序的编写。该系统主要是完成长期连续监测,远程采集设备自动收集土壤墒情即时数据,并通过GPRS来实现无线网络远程的数据传送;监测中心可自动接受数据、自动存储到监测点所在的数据库中。可以根据监测需要,灵巧安插土壤水分传感器;传感器可以安插在不同的深度部分测量土壤水分情况。土壤墒情监测系统可以很全面、科学的、比较真实地反应被监测土壤的变化,可及时、较准确的给出监测点的土壤墒情状况,为减少灾难和抗旱性提供重要的信息。本文要点是墒情信号收集、处理、数据无线输送和实时远距离监测土壤墒情,设计了一套完整的墒情信号采集处理,基于GPRS的墒情数据输送和远程监测中心对墒情数据分类显示、图形分析以及自动存储的系统。设计了基于GPRS的数据输送技术的监控系统的客户端。本文给出了系统的硬件和软件结构,墒情信号的采集处理和墒情数据输送的方法和过程,对系统软件的通信方法、程序的构造和详细的功能进行分析。本文联系实验和具体应用对系统特性进行了研究和分析。作为一个现实应用的系统,基于GPRS的墒情数据无线监测系统全面考虑了现实运行的需要。
[Abstract]:During the growth period of crops in China, because of the low precipitation, the lack of rivers and other water resources, the water content of the soil is relatively low, and the water demand of crops for a long period of life is less than the amount of water provided.Damaged the normal growth of crops, affected the production and life of people.Precision agriculture is the development direction of agriculture in China. If we want to establish a precision agriculture system that is suitable for China, we must build an information management model suitable for precision agriculture.In order to increase the level of agricultural drought resistance, dynamic understanding of land drought changes, reduce the losses caused by drought, the establishment of a wide coverage of soil moisture monitoring system has become an important agricultural sector Ren Wuzhi.This paper studies a form of precision agriculture: soil commercial data wireless monitoring system.Soil moisture generally refers to soil moisture conditions.Soil moisture is one of the important conditions for seed emergence, growth and yield formation.Paying close attention to farmland moisture and its change can provide scientific basis for real-time agriculture to adopt irrigation or drainage.The soil moisture monitoring system designed in this paper mainly completes the hardware design and software design of the soil moisture monitoring station.And the GPRS module is analyzed and introduced in detail, and the whole circuit diagram of the monitoring system is analyzed.The main part of the software is the compilation of a series of programs for moisture collection.The system is mainly to complete long-term continuous monitoring, remote acquisition equipment automatically collect soil moisture real-time data, and through GPRS to achieve remote wireless network data transmission, monitoring center can automatically accept data,Automatically store in the database where the monitoring point is located.According to the monitoring needs, the soil moisture sensor can be inserted dexterously, and the sensor can be used to measure the soil moisture in different depth.The soil moisture monitoring system can completely, scientifically and truthfully reflect the change of the monitored soil, and can give the soil moisture condition of the monitoring point in time and accurately, which can provide important information for reducing disaster and drought resistance.The main points of this paper are soil moisture signal collection, data processing, wireless data transmission and real-time and remote monitoring of soil moisture. A complete set of soil moisture signal collection and processing is designed.The system of soil moisture data transmission and remote monitoring center based on GPRS is used to classify and display moisture data, graph analysis and automatic storage.The client of the monitoring system based on GPRS technology is designed.In this paper, the hardware and software structure of the system, the method and process of collecting and processing the moisture signal and the conveying of moisture data are given. The communication method of the system software, the construction of the program and the detailed function are analyzed.In this paper, the characteristics of the system are studied and analyzed in combination with experiments and specific applications.As a practical application system, the wireless monitoring system of soil moisture data based on GPRS takes into account the need of practical operation.
