摘要 随着现代农业的快速发展,设施农业已经成为现代农业发展的重要手段,并在世界各地被广泛应用。与此同时,设施农业的研究也是科研项目的重要课题。温室检测系统作为设施农业的重要组成部分,是实现温室自动化、科学化的基本保证。由于温室环境系统的复杂性,如何通过设定合理的控制目标作为作物生长提供适宜的环境,同时最大限度利用自然资源,降低温室的能源损耗都是需要深入研究的方向。
本文结合传感器技术和微型单片机控制技术,结合现代农业的控制策略,设计了一套温室温、湿度监测系统,并重点对传感器组织网络进行研究。同时依据温室系统低功耗要求在硬件设计方面也进行了甄选。
文章首先向读者介绍国内外温室控制课题的研究现状和未来的发展动态,同时对选取本课题的意义进行必要的说明,提出设计和实现方案。本文所设计的系统可以分为两大部分:第一是温室参数测量部分;第二是数据采集处理部分。参数可分为三个基本内容:温度测量、湿度测量和光照强度测量。温度测量采用TI公司的温度传感器DS18B20,单总线输出温度数字值给单片机,经由控制芯片处理后显示;湿度测量采用瑞士Sensirion 公司设计的SHT11温湿度传感器。
由单片机最小系统及系统外围接口电路组成单片机数据采集处理部分。系统外围接口电路包括以下五个基本环节:
键盘部分、显示部分、日历部分、电源电压部分、存储部分。
本设计软件部分采用C语言编写,完成温度、湿度、光照强度循环测量和日历的实时显示。
最后,本文对设计的智能农业气象站设计进行了总结,分析了系统的不足和改进方向,以便为下一步的研究做好工作。

Smart Agricultural Station Design
ABSTRACT With the rapid development of modern agriculture, agricultural facilities has become an important means of modern agricultural development, and is widely used around the world. At the same time, agricultural research facilities is also an important subject of research. Greenhouse detection system as an important part of agricultural facilities is to achieve greenhouse automation, scientific basic guarantee. Due to the complexity of the greenhouse system, how to provide a suitable environment for the growth of crops, while maximizing the use of natural resources, reduce energy consumption greenhouse direction are studied in depth by setting reasonable goals as a control.
In this paper, sensor technology and micro-chip control technology, combined with the control strategy of modern agriculture, designed a greenhouse temperature, and focuses on the sensor network organization, greenhouse control strategy research. While low power requirements based on the greenhouse system hardware design also carried out the selection.
At the first, this paper describes the current research and developments in the domestic and international greenhouse control system, while the significance of this topic, select the demonstration, and presents the design and implementation of specific programs.
The first parameter is a measure of greenhouse part; second part is the data acquisition and processing. Parameters section includes three basic elements: temperature measurement, humidity measurement and light intensity. Temperature measurement using TI's temperature sensor DS18B20, single-bus digital temperature output value to the microcontroller, via post processing display; humidity measurement using SHT11 sensor.
SCM data acquisition and processing system, and in part by the smallest single-chip system peripheral interface circuit. System peripheral interface circuit consists of the following five basic components:
A keyboard section, a display section, the calendar section, the supply voltage section, a storage section.The design software using C language, temperature and humidity to complete the cycle of light intensity measurement within the real-time display and calendar. Finally, the design of intelligent design agricultural weather stations were summarized and analyzed the shortcomings of the system and improve the direction to do the work for the next study.
