. 毕业设计(论文) 题目:水温控制系统专业:班级:学号:姓名: 指导老师: . 摘要本文从硬件和软件两方面讲述自动控制水温的过程,在控制过程中主要应用 AT89C51 、ICL7109 、LED 显示器、OP07 放大器等芯片,并对它们的工作原理进行了具体的介绍,还介绍了温度控制系统的工作原理和设计方法。首先,文中介绍了该控制器的硬件部分。包括:温度检测电路、温度控制电路和一些接口电路。此外,文中还介绍了软件设计部分。主要模块有:主程序、中断服务程序、采样程序、温度控制程序。水温自动化控制的过程是:首先,通过设置按键,设定恒温运行时的温度值,,在运行过程中将采样的温度模拟量送入 A/D 转换器中进行模拟-数字转换,再将转换后的数字量用数码管进行显示,最后用单片机来控制加热器,进行加热或停止加热,直到能在规定的温度下恒温加热。本设计也可用于其它的温度控制系统。关键词:单片机系统传感器数据采集模数转换器温度. Abstract Inthis article, itincludes one-puter AT89C51, ICL7109 ,LED display equipment and pare equipment. Inthe index, ithas two chips. One isthe program. The other isthe translation. This paper introduces the principle and the designing methods oftemperature controller. Atfirst, the paper gives the hardware parts onthis system. These circuits include: temperature monitor, temperature controller and afew meets. Inaddition, the main ofthis paper isthe software parts. The main modules include: The main routine ,interrupt service routine, sampling routine, temperature control system. The water temperature automates the process ofthe control is: First, pass toestablish key, set upthe temperature value for constant temperature tocirculate, and show this temperature the value with the figures tube. Then, proceed inprocess lieutenant general that circulate temperature adopt kind imitate deal sent into A/D conversion machine the emulation- arithmetic figure convert, using the amount ofarithmetic figure after converting tofigures again the tube proceed the manifestation, using the single amachine finally tocontrol the heating apparatus, proceeding the heating orstopping the heating, until can under the prescriptive temperature the constant temperature heats This design can beused for the others oftemperature controller mon.
