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 effectively the prediction of the accidents and the work efficiency.This system is proceeded by AD590 and HS1100 the signal collects, through MC14433 go to transformation the signal from simulation to figure, And handling the signal in the 8031 of the MCU basic systems. And the system also has the functions of alarm and the display.Passing the controling of computer not only can make separation between mans and the machine, and aslo saving the resources of the manpower and the materials,and the design builds’s price is very low. Therefore, It is a ideal design for temperature-humidity control system.Keywords: MCU、Temperature Sensor、 Humidity Sensor、 A/ D conversion 、Display目 錄第一章 緒論 ....................................................................................................11. 1 選題背景 ...........................................................................................11．2 設(shè)計(jì)過程及工藝要求 ..........................................................................2第二章 方案的比較和論證 ..............................................................................22. 1 溫度傳感器的選擇 ..................................................................................32. 2 濕度傳感器的選擇 .................................................................................32. 3 信號采集通道的選擇 .............................................................................4第三章 系統(tǒng)總體設(shè)計(jì) .....................................................................................53．1 信號采集 .............................................................................................63．1．1 溫度傳感器 ..............................................................................63. 1. 2 濕度傳感器 ................................................................................93．1．3 多路開關(guān) .................................................................................123．2 信號分析與處理 ......................................................錯(cuò)誤！未定義書簽。3．2．1 A/D 轉(zhuǎn)換 ......................................................錯(cuò)誤！未定義書簽。3. 2. 2 單片機(jī) 8031....................................................錯(cuò)誤！未定義書簽。3. 2. 2. 1 8031 的片內(nèi)結(jié)構(gòu) ......................................錯(cuò)誤！未定義書簽。3. 2. 2. 2 8031 的引腳圖 ...........................................錯(cuò)誤！未定義書簽。3. 2. 2. 3 8031 程序存儲器 .................................................................193. 2. 2. 4 8031 數(shù)據(jù)存儲器 ......................................錯(cuò)誤！未定義書簽。3. 2. 2. 5 特殊功能寄存器 SFR.................................錯(cuò)誤！未定義書簽。3. 2. 2. 6 工作方式 .................................................錯(cuò)誤！未定義書簽。3. 2. 3 存儲器的設(shè)計(jì) .................................................錯(cuò)誤！未定義書簽。3. 2. 4 數(shù)據(jù)存儲器的掉電保護(hù) ...................................錯(cuò)誤！未定義書簽。3. 2. 5 系統(tǒng)時(shí)鐘的設(shè)計(jì) ..............................................錯(cuò)誤！未定義書簽。3. 3 顯示與報(bào)警的設(shè)計(jì) ....................................................錯(cuò)誤！未定義書簽。3. 3. 1 顯示電路 .......................................................錯(cuò)誤！未定義書簽。3. 3. 2 報(bào)警電路 .......................................................錯(cuò)誤！未定義書簽。第四章 軟件設(shè)計(jì) .................................................................錯(cuò)誤！未定義書簽。附錄 A 程序清單 .....................................................................錯(cuò)誤！未定義書簽。
