粮仓的温湿度监测系统设计 -  PAGE 37 - 粮仓的温湿度监测系统设计 摘要 随着单片机技术和工业生产自动化程度的不断提高，单片机测控技术已得到了广泛的推广和应用。这种单片机的测试技术为工业控制、家用电器和仪器仪表智能化的应用提供了一种全新的、有效的测试方法，并具有很大的实用意义和前景。 本文根据粮仓环境测试的特点，应用现代检测理论，对温室的温度、湿度等环境因子进行自动检测，完成了整个监测检测系统的软、硬件设计。 第一章对粮仓自动监测系统的发展背景及现状作一简单介绍，并确定了本论文的设计方向;;第二章介绍了系统的硬件设计;第三章介绍了系统软件的模块化设计;最后对整个系统的改进提出几点建议。 关键词 : 粮仓；现代检测技术；单片机；微处理器 Abstract With the continuous development of the microprocessor technology and industry automation level,the technology of microprocessor test has been widely spread and applied.This technology was based on modern test theory and provided a kind of fire-new and effective control method in application of industry control, household appliances and instrument intelligence, it has prodigious practical use and prospect. In this paper, according to the character of environment test in graindepot, we applied modern theory to realize auto-test to temperature and humidity. We accomplished the software and hardware design of the whole test system finally. In the first chapter, the paper introduced simply the background and development condition of auto-test system in grand put in graindepot forward the research subject. In the second chapter, this paper introduced hardware design of system. In the third chapter,, the paper introduced software design of system. Finally, several pieces of suggestions were put to improve the whole system. keywords: Graindepot ;Modern test technology; Microprocessor 目录  TOC \o 1-2 \h \z \u  HYPERLINK \l _Toc229665444 摘要 Ⅰ  HYPERLINK \l _Toc229665485 Abstract Ⅱ 目录  PAGEREF _Toc199314014 \h IV 第一章 HYPERLINK \l _Toc199314015  绪论 1  HYPERLINK \l _Toc199314016 1.1研究的背景和意义 1 1.2温度传感器技术的国内外研究动态…………………………...1  HYPERLINK \l _Toc199314021 1.3湿度传感器技术的国内外研究动态…………………………...2 1.4 本课题的主要研究目标及内容……………………………….2 第二章 器件简介……………………………………………………… 2.1 AD590简介……………………………………………………… 2.2 ADC0809 简介………………………………………………… 第三章 系统的硬件设计3 3.1总体设计…………………………………………………………4 3.2信号采样电路设计………………………………………………5 3.2.1温度
