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.
