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

本文是一篇名为“基于SVM的石油勘探算法研究”的硕士论文，文中应用MATLAB进行算法实现，给出了详细的设计思路，各种不同方法的图像对比，区县调整，是一片相当不错的文章。-This is the one entitled "SVM Based Algorithm for oil exploration," the master"s thesis, text MATLAB algorithm is given a detailed design ideas, different methods of image contrast. county adjustment is a pretty good article.

模数 转换器的设计是一个巨大挑战，因为它具有必须在系统级加以考虑的各种不同的输入采样结构。本文将探讨几种通用的输入采样结构，并讨论每种结构对系统其它部 分的影响。-ADC is designed to be a great challenge, because it has to be at the system level to be taken into account a variety of different input sampling structure. This article will explore several common input sampling structure, and discuss each type of structure on the impact of other parts of the system.

按功能目标的不同可将电子政务的系统功能分为以下三类：内容管理（Content Management）、协同处理（Collaboration）与内务服务（Business service）。-according to the function of the different objectives of the e-government system functions are divided into the following three categories : content management (Content Management), synergistic processing (Collaboration) and the House (Business service).

这个个系统是学生管理系统。利用SDK做界面，用双向链表做排序，功能简单，但是思路清晰，有不到指出多原谅-systems is the Student Management System. Do use SDK interface, so with two-way linked list, in order of functions simple, but clear ideas that are not more forgiving
