毕业论文-基于单片机的燃油炉温度控制系统设计,共45页,15905字
摘要
随着科学技术的不断发展,单片机作为优秀的低端控制器的优良特性已经是深入人心,单片机具有集成度高,运算快速快,体积小、运行可靠,价值低廉,因此在过程控制、数据采集、机电一体化、智能化仪表、家用电器以及网络技术等方面得到广泛应用,本文主要介绍单片机在炉温控制中的应用。
在工业生产中,有很多行业有大量的加热设备,如用于热处理的加热炉、用于熔化金属的坩埚炉,以及各种不同用途的加热炉,反应炉,这样温度就成为了工业对象中一种重要的被测控对象,但是由于炉子的种类,用途不同,因此,采用的加热方法及燃料也就不同,如煤气、天然气、油、电等,但究其控制系统本身的动态特性而言,基本上都是一阶纯滞后环节。实践证明,用于工业生产中的炉温控制的微机控制系统具有高精度、功能强、经济性好的特点,无论在提高产品质量还是产品数量,节约能源,还是改善劳动条件等方面都显示出无比的优越性。

Abstract
With the continuous development of science and technology, as a good low-end microcontroller superior characteristics of the controller is already deeply rooted among the microcontroller with an integrated high, fast-fast operation, small size, reliable operation, value low, so the process control, data acquisition , electromechanical integration, intelligent instruments, appliances and network technology, etc. are widely used, this article introduces the MCU in the furnace temperature control applications.
In industrial production, there are many industries a large number of heating equipment, such as for heat treatment furnace for melting the metal crucible furnace, and a variety of different uses of the furnace, reactor, so that the temperature has become an industrial object have been an important monitoring and control objects, but because of the stove types, use of different and, therefore, using the heating method and fuel is different, such as coal gas, natural gas, oil, electricity and so on, but their real control of the system itself in terms of the dynamic characteristics of basically a first-order pure delay link. Practice has proved that for the industrial production of furnace temperature control, computer control system with high precision, strong function, economy and good characteristics, in terms of improving product quality or the number of products, energy conservation, or improving working conditions, etc. have shown incomparable superiority.
Key words:The monolithic integrated circuit, Fuel oil is called the hot stove, Temperature control
