摘  要
 隨著電氣技術(shù)、微電子技術(shù)與計算機(jī)技術(shù)的飛速發(fā)展，倉貯系統(tǒng)檢測、控制、管理自動化己迫在眉睫，尤其是近年來倉貯系統(tǒng)的容量不斷擴(kuò)大，傳統(tǒng)的方式已經(jīng)遠(yuǎn)遠(yuǎn)不能滿足實際生產(chǎn)的需要，所以建立一種管理科學(xué)、操作簡便、運(yùn)行可靠的高效率軟硬件已是必需的。
 庫房的原有溫濕度檢測都是采用人工檢測和控制，方法老化，控制設(shè)施滯后，如果采用一般倉貯遠(yuǎn)程監(jiān)控，即重新布線或借助于電力線進(jìn)行信號傳輸，施工勞動強(qiáng)度大，投資大。本設(shè)計以科技創(chuàng)新的觀點(diǎn)，研究與設(shè)計以代機(jī)為控制核心，采用數(shù)字溫度和濕度傳感器的自動測控系統(tǒng)，對庫區(qū)的溫度及濕度的變化情況進(jìn)行實時自動測試，實時顯示和監(jiān)測各個倉庫的環(huán)境變化情況，通過適當(dāng)?shù)能洝⒂布�抗千擾處理和控制室計算機(jī)的分析處理，實現(xiàn)現(xiàn)場的控制，使倉庫達(dá)到恒溫、恒濕狀態(tài)，從而提高倉庫的科學(xué)管理化、控制自動化水平，對有效地提高事故的預(yù)見性和工作效率有著重要的實際推廣價值和理論研究意義！

Abstract
 With the development of electric technology, micro-electronics technology and computer technology, the new examination, controlling and automatic management of storage system has been in great need. As the capacity of storage system has been broadening since recent years, the traditional storage way has been far cry from demand in real productivity, so it’s necessary to set up a kind of software and hardware facility with scientific management, simple operation, safe function and efficiency.
 the original examination system of temperature and humidity in workshop was executed and controlled by manpower. However this way has become old, including its controlling facilities.instead, if it adopts a common long-distance monitoring storage, it will be an expensive investment and high intensity in working construction.The new design, based on scientific innovation, takes PC as the controlling core and adopts automatic monitoring system specializing in signify temperature and humidly sensor. the design could state and monitor the changing condition, which be controlled in every warehouse through appropriate software like computer, so it could make the temperature and humidity in constant condition. With help of the design, it is able to improve the scientific management and automatic control of storage; it is also of great value and significance to forecast the rate of accident in storage and to improve the efficiency in detailed working.

Key words: storage condition; automatic sensor; automatic dialysis system
