基于单片机的水温控制系统
【摘要】温度是工业控制对象主要被控参数之一,在温度控制中,由于受到温度被控对象特性(如惯性大、滞后大、非线性等)的影响,使得控制性能难以提高,有些工艺过程其温度控制的好坏直接影响着产品的质量,因而设计一种较为理想的温度控制系统是非常有价值的。为了实现高精度的水温测量和控制,本文介绍了一种以Atmel公司的低功耗高性能CMOS单片机为核心,以PID算法控制以及PID参数整定相结合的控制方法来实现的水温控制系统,其硬件电路还包括温度采集、温度控制、温度显示、键盘输入以及RS232接口等电路。该系统可实现对温度的测量,并能根据设定值对温度进行调节,实现控温的目的。

The summary: Temperature is the main control of industrial control of parameters, In temperature control, due to temperature controlled object properties (such as inertia big, big, lagging effect of nonlinear, etc.), to improve performance, some process temperature control of its direct impact on the quality of the product, and designed a kind of ideal temperature control system is a very valuable. In order to realize high precision temperature measurement and control, this paper introduces a meter taking pany low-power high-performance CMOS chip as the core, and the PID control algorithm with PID bination of control method to realize the temperature control system, the hardware circuit including temperature, temperature control, temperature gathering, keyboard input and RS232 interface circuits, etc. The system can realize the measurement for temperature, and can according to value of tem
