程序员对代码所做的为了满足短期利益代码改动，或再没有完全清楚增个架构下的改动，都很容易是代码失去它的清晰结构，偏离需求或设计。而这些改动的积累很容易使代码偏离它原先设计的初衷而变得不可立即和无法维护。 Refactoring则帮助重新组织代码，重新清晰的体现结构和进一步改进设计。 -programmers to code done in order to meet short-term interest code changes or not entirely clear by a framework of the changes, it is easy to lose its code is a clear structure, depart from the demand or design. And the accumulation of these changes are easier to make code from its original intention of the original design has become an immediate and unable to preserve. Refactoring is helping to reorganize code, re- clearly reflected structure and further improve the design.

摘要】 本文介绍了以AT89S51单片机为核心的温度控制器的设计,在该设计中采用高精度的温度传感器AD590对电热锅炉的温度进行实时精确测量,用超低温漂移高精度运算放大器OP07将温度-电压信号进行放大,再送入12位的AD574A进行AD转换,从而实现自动检测,实时显示及越限报警。控制部分采用PID算法,实时更新PWM控制输出参数,控制可控硅的通断时间,最终实现对炉温的高精度控制。 【关键词】 水温控制系统 PID控制单片机 温度控制是工业生产过程中经常遇到的过程控制,有些工艺过程对其温度的控制效果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。 一 系统设计方案的论证与比较 根据题目要求,电热锅炉温度控制系统由核心处理模块、温度采集模块、键盘显示模块、及控制执行模块等组成。-Abstract This paper introduces the single-chip AT89S51 temperature controller at the core of the design, in the design of high-precision temperature sensor AD590 temperature of the heating boiler accurate measurement of real-time, using ultra-low temperature drift, high-precision operational amplifier OP07 temperature Part of the use of PID control algorithms, real-time PWM control output parameter update and control the on-off Thyristor time, finally achieve the high-precision control of temperature. 【Key Words】 temperature control system PID control of single-chip Temperature control is the process of ind
