温湿度测量仪102 双击自动滚屏 文章来源：一流设计吧 发布者：16sheji8 发布时间：2008-08-18 09:44:44 阅读：920次 摘要 为保证仓库日常工作的顺利进行，首要问题是加强仓库内温度与湿度的监测工作。
但传统的方法是用湿度表、毛发湿度表、双金属式测量计和湿度试纸等测试器材，通过人工进行检测，对不符合温度和湿度要求的库房进行通风、去湿和降温等工作。这种人工测试方法费时费力、效率低，且测试的温度及湿度误差大，随机性大。
因此我们需要一种造价低廉、使用方便且测量准确的温湿度测量仪。本系统研制了以PC机为控制核心，基于AD590及HS1100传感器的温度和湿度自动检测系统。
这个系统能够对库区内每个库房中各仓位的温度及湿度的变化情况进行实时自动检测，一旦出现异常现象便于及时处理，有效地提高了事故的预见性和工作效率。本系统由AD590及HS1100进行信号采集，经过MC14433对采集到的模拟信号进行数模变换，在单片机8031基本系统中进行数据处理，并具有实时显示及报警等功能。
通过计算机控制可以实现人机分离，节省人力物力，且本设计造价低，是比较理想的温湿度检测系统。关键词： 单片机 温度传感器 湿度传感器 A/D转换 显示 Abstract For guaranteeing the warehouse daily smoothly progress, the major problem is to enhances the monitoring of the temperature and the humidity inside the warehouse . The traditional method is to use testing devices of Hygrometer, Hair Hygrometer, Double Metals measuring and Humidity Paper etc. Passing the labour power proceed examination, to match with the temperature and humidity requesting to proceed ventilating, reducing the Damp and the temperature etc. This kind of artificial testing method Wasted a lot of time and the efficiency is very low,and the error is big. Therefore we need a kind of device that is the price cheaply, usage Conveniently and accurated measure the temperature and the humidity .The design of this system is consist of to the machine of PC that as to control core, according to AD590 and HS1100 measure automatically the temperature and the humidity.This system can be getting to the automatic examination for the variety circumstance between the temperature and the humidity of every areas inside the warehouse, once appearing the abnormality phenomenon is easy to handle,therefor the system increases [1] [2] [3] [4] 下一页 本文来自： 一流设计吧（） 详细出处参考： /42-2/2774.htm
