. .. 温度监控系统的设计 ——系统的软件设计 指导老师：** 老师 摘 要 随着科技的发展，相较于很多年以前人们对于自己生活的需求也发生了戏剧性的改变。而监控系统恰恰迎合了人们的这一需要。在众多先进测量控制技术中，由于单片微处理器的性能日益提高、价格又不断降低，使其性能价格比的优势非常明显并且我们知道利用MATLAB可以方便地进行仿真整定PID参数。本文介绍一个以单片机为核心的温度监控系统，主要包括控制算法的仿真分析（用MATLAB）和软件编程（用C51），它是利用传感器采集温度信号, 温度信号经放大电路放大、A／D转换后送到单片机中，并将温度值显示在数码管上，单片机把它同由键盘实现的给定温度进行比较，再由单片机根据控制策略给出控制量，然后将控制量送驱动电路驱动加热装置和报警装置，从而构成了实时闭环系统。 本人主要负责系统的软件设计，在软件设计过程中，我们尽可能使其功能化、模块化、尽量采用子程序调用的方法。 【关键字】单片机；温度监控系统；PID控制算法；MATLAB；软件设计（C51）。 Abstract With the increasing pace of science and technology, perhaps no change has characteristic the past decades more dramatic than that of people’s demands of their own life. Supervision and monitoring system meet the requirements of them. In these numerous advanced measurement and control technology, because of the enhanced performance and reduced price of MCU, making the advantage that its ratio of performance to price been obvious and as we know MATLAB is easy to simulate the setting of PID parameter. This text, which comprised by the simulation and analysis of control algorithms (using MATLAB) and the program of software (using C51), introduces a temperature monitor whose core is a MCU. It gathers the temperature signal and amplifies it by an amplifier circuit microcomputer. Simultaneity sends it into the MCU after A/D conversion. Then show it on in the LED. The single chip compares it with the temperature， which realizes by the keyboard and give control measure according to the control strategy. In the end, the MCU sends control measure to drive circuit in order to drive the heating installation and warning device. And a closed system is formed. I am mainly responsible for the software design of the system .In process of the software design; we make its function, modularization and use subroutine as far as possible.
