PAGE 38 7 - 智能水温控制系统的设计 摘要：近年来随着科技的飞速发展，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异更新。本文给出了一个基于 AT89C51 单片机控制的水温智能控制系统。重点阐述了系统的硬件构成，各部分的主要作用及系统软件的设计过程。设计方案的核心部件是80C51，通过硬件及软件的合理设计，使系统能满足控制模型中不同阶段的要求。系统的采集模块采用了AD590温度传感器作为测温元件，而控制模块则通过控制可控硅的导通和截止，从而控制加热电压的通与断，使控制具有灵敏、可靠、抗干扰能力强等优点。水温直接由人工设定，并能在环境温度变化时实现自动调整以保持设定的温度基本不变，实测水温用十进制数码管显示输出。 关键词：智能控制；水温控制；数据采集；温度传感器 A Design Of Water Temperature Brainpower Controlling System Abstract：The paper main design a brainpower controlling system of water temperature based on MCS-51. It expounds emphatically the hardware structure of the system, the main function, and the process of the system software design. The core of the design is MCS-51. Through reasonable design of hardware and software to make the system meet the demands of different phases of the control model, the collection module of the system uses AD590 as the element of the temperature measurement, and the control module uses the optical shutter. The heating voltage is controlled by optical shutter, the control has the advantages of sensitive and dependable and strong ability of resisting disturbance. The water temperature may be set at some degree by manpower and auto-adjusted as environment is cool, so the water temperature keeps constantly and is displayed in decade.
