基于单片机S12的锅炉调功恒温控制系统 摘要 伴随着计算机在电子科学技术领域的发展,?同时单片机的应用也正在不断地走向深入与成熟，并且使得电子检测技术不断地更新。? 本毕业设计从两方面（软件和硬件）来讲述基于单片机的锅炉调功恒温控制系统。选用了MC9S12 单片机、双向可控硅、DS18B20温度传感器、12864显示器、光电耦合等组成温度控制系统。以实现对锅炉温度加热到最大温度100??的快而准确的控制。选用单总线温度传感器 DS18B20作为温度采集器,对实时温度进行采集。通过按键可以控制加热的开始和停止，同时对想要达到的预设水温进行设定。与此同时显示模块会显示预设水温值和当前水温值。单片机连接光电耦合从而控制双向可控硅的通断时间以改变电热管的加热功率的大小，从而实现恒温调功并稳定在预设值上。本设计分为五章，全面介绍了本系统的设计过程。 关键词：恒温调功 ；单片机系统；传感器；温度采集 Boiler tuning work temperature control system based on single-chip computer speed 12 Abstract With the development of computer science in the field of electronic technology, and SCM applications are also being constantly deepening and maturity, and makes electronic detection technology constantly updated. The graduation project in two ways (software and hardware) to tell the boiler temperature control system power adjustment based microcontroller. MC9S12 chosen microcontroller, triac, DS18B20 temperature sensor, 12,864 monitors, optical couplers and other components temperature control system. In order to achieve maximum boiler temperature to 100 ? fast and accurate temperature control Σs. Selected as a single-bus temperature sensor DS18B20 temperature acquisition, real-time temperature acquisition. Can be controlled by the key start and stop of heating, while trying to achieve the preset temperature set. At the same time temperature display module displays the default value and the current temperature value. SCM connection optocoupler triac to control the on-off time to change the heating power of the heating pipe size, in order to achieve a constant temperature stable power adjustment and the default value. The design is divided into five chapters, a comprehensive introduction to the design process of the system. Keywords: thermostat power adjustment; SCM system; sensor; temperature acquisition 第1章：绪论 本章主要从整体方向阐述课题研究的背景意义和课题任务。 1.1课题研究背景及意义 锅炉的应用从公用到民用已经遍布我们身边各个角落，可谓是随处可见。一般来说锅炉是热能转换设备的一种，锅炉包含锅和炉两大主体保证了它能安全经济的连续运行，除此还有一些附属设备比如：仪表、控制系统等。在锅炉系统中燃烧燃料释放出来的能量不断地对水进行加热，水温不断的升高
