摘 要
隨著電究所子技術(shù)的發(fā)展，微處理器、集成電路不斷更新、發(fā)展，溫度是工業(yè)生產(chǎn)和自動控制中最常見的工藝參數(shù)之一，任何物理變化和化學(xué)變化的過程都與溫度密切相關(guān)，因此，在生產(chǎn)過程中常需對溫度進(jìn)行檢測和監(jiān)控。采用單片機(jī)進(jìn)行溫度檢測、數(shù)值顯示和數(shù)據(jù)的存儲，效率高，性能穩(wěn)定，還可以實現(xiàn)實時控制等技術(shù)要求，在工業(yè)生產(chǎn)中應(yīng)用越來越廣泛。
單片機(jī)在電子產(chǎn)品中的應(yīng)用已經(jīng)越來越廣泛，在很多的電子產(chǎn)品中也用到了溫度檢測和溫度控制。隨著溫度控制器應(yīng)用范圍的日益廣泛和多樣，各種適用于不同場合的溫度控制器應(yīng)運而生。
隨著人們生活水平的不斷提高,單片機(jī)控制無疑是人們追求的目標(biāo)之一，它所給人帶來的方便也是不可否定的，其中雞雛恒溫孵化器就是一個典型的例子，本設(shè)計所介紹的雞雛恒溫孵化器，具有讀數(shù)方便，測溫范圍廣，測溫準(zhǔn)確，其輸出溫度采用數(shù)字顯示，主要用于對測溫比較準(zhǔn)確的場所，或科研實驗室使用，該設(shè)計控制器使用單片機(jī)AT89C51，測溫傳感器使用DS18B20，用液晶LCD1602實現(xiàn)溫度顯示。

Abstract
 investigates the sub-technical development along with the electricity, the microprocessor, the integrated circuit renews, the development, the temperature is unceasingly in the industrial production and the automatic control one of most common technological parameters, any physical change and chemical change's process closely is related with the temperature, therefore, Chang Xu carries on the examination and the monitoring in the production process to the temperature. Uses the monolithic integrated circuit to carry on the temperature examination, the value demonstration and the data memory, the efficiency is high, stable property, but may also realize specifications and so on real-time control, applies in the industrial production is getting more and more widespread. the monolithic integrated circuit's was already getting more and more widespread in electronic products application, also used the temperature examination and the temperature control in many electronic products. Is day by day widespread along with the temperature controller application scope and is diverse, each kind is suitable in the different situation temperature controller arises at the historic moment. along with the people living standard's unceasing enhancement, the monolithic integrated circuit control is one which of without doubt goals the people pursue, it the convenience which brings to the human also not whether to decide, the chicken young constant temperature hatchibator is a typical example, this design introduced the chicken young constant temperature hatchibator, has the reading to be convenient, the temperature measurement scope is broad, the temperature measurement is accurate, its output temperature uses the digit to demonstrate, mainly uses to the temperature measurement quite accurate place, or the scientific research laboratory use, this design controller use monolithic integrated circuit AT89C51, the temperature measurement sensor uses DS18B20, realizes the temperature demonstration with liquid crystal LCD1602.
