摘 要

 随着社会的进步，人民生活水平的不断提高，酒文化也随之不断发展。为了使酒能够在良好的环境下保持原有的新鲜并且更显优秀品质，这就对酒窖的各项指标提出更高的要求。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酒窖进行通风、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。本系统研制了以单片机为控制核心，基于传感器的温度和湿度自动检测系统。这个系统能够对酒窖内多个点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。
 本系统由传感器进行信号采集，在单片机中进行数据处理，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。

The wine cellar warm humidity control system supposes discusses

Abstract
Along with the progress of the society, the people are living level of raise continuously,the wine culture also develops immediately and continuously.For canning make the wine keep original fresh and more excellent quality under the good environment, this put forward a higher request to various index signs of bodega.But the traditional method is to use the hygrometer, hair hygrometer, double metals type diagraph to account to try paper with degree of humidity etc. test device, carry on an examination through an artificial, carry on to the bodega which not agrees with to match temperature and degree of humidity to request well ventilated, go to wet with reduce the heat etc. work.This kind of artificial test method is time-consuming hard to tackle, the efficiency is low, and test of temperature and degree of humidity error margin big, random big.So we need 1 kind to build price cheap, the usage is convenient and measure accurate degree of humidity diagraph an instrument.This system developed with single slice machine for control core, according to spread temperature and degree of humidity of feeling machine to examine system automatically.This system can to many variety circumstances of temperature and degree of humidity for ordering inside the bodega carry on solid hour auto examination, once appearing excrescent phenomenon easy to handle in time, raise to settle a dispute availably past of foresee sex and work efficiency.
This system from spread a feeling machine to carry on signal to collect, carry on a data processing in the single slice the machine, and have solid hour show and report to the police etc. function.
Passing the calculator control can carry out person''s machine to separate, saving manpower material resources, and this design build price low, is a more ideal degree of humidity examination system.
