本科生毕业设计（论文） 中文题目： 基于PID算法和51单片机的温度控制系统 英文题目： 院 系： 机械电子工程学院 专 业： 自动化 姓 名： 学 号： 指导教师： 完成时间： 摘 要 近年来随着计算机在社会领域的渗透, 单片机的应用正在不断地走向深入，同时带动传统控制检测日新月益更新。在实时检测和自动控制的单片机应用系统中，单片机往往是作为一个核心部件来使用本文从硬件和软件两方面来水温自动控制过程,在控制过程中主要应用AT89C5、LD1602显示器、，以单片机为核心控制部件，通过 DS18B20数字温度传感器采集环境温度显示实时温度。软件方面采用语言来进行程序设计，。为了便于扩展和更改，软件的设计采用模块化结构，使程序设计的逻辑关系更加简洁明了，使硬件在软件的控制下协调运作。 而系统的过程则是：通过按键,设定恒温运行时的温度值用显示这个温度值.在运行过程中将采样的温度再将转换后的数字量用进行显示，，直到能在规定的温度下恒温加热。 关键词：单片机系统；传感器；；温度In recent years, with the computer penetration in the social field, the application of SCM is to keep at the same time, traditional control testing update on Crescent benefits. In real-time detection and automatic control system of single-chip applications. often as a single-chip core component to use only single-chip is not enough knowledge, but also the specific hardware structure and the specific features of application software objects combine to make perfect. In this paper, both hardware and software for automatic control of water temperature on the process, in the control of the main application of the process of AT89C52, LCD1602, MOC3051, microcomputer as the core control components, through the digital temperature sensor DS18B20 collecting ambient temperature and through Liquid Crystal Display1602 display of a digital thermometer temperature. Software using C language for programming, so that making it easier for the programming, to save storage space. In order to facilitate the expansion and changes to the design of modular software structure, so that the logic of the relationship between program design more concise,Hardware software co-operation under the control of it. And systematic process is: First of all, by setting the matrix keyboard, set the thermostat temperature at the time of DS18B20, and digita
