文档介绍：摘要
本论文对远程温度数据的采集与控制温度进行了详细的阐述。主要讲述了一个在计算机远程控制下,利用单片机对远程温度进行采集显示并控制温度的增长。同时通过PC机对PWM波输出进行PID调整。并给出其软硬件设计及调试。在论文完成过程中,主要进行了以下工作:
对系统要求进行分析,并设计系统的整体结构
把整体细分化,对每个模块进行详细设计
绘制原理图和PCB图,并制成实验板
按照硬件电路,编写软件程序
调试阶段,调试各软、硬件模块,编写测试程序,验证系统的可用性,最后制成系统样机。
本论文主要对远程温度采集与控制系统进行了较详细的阐述。软件的三大模块:采集模块、PID控制、上下位机通讯,并对主要芯片的使用做了说明。对硬件电路的数据采集、数据设定及显示部分作较详细的阐述。介绍了整体硬件的实现方案。
另外,在本文中,还介绍了在绘制原理图和PCB图时所用的工具及需要注意的问题。例如,电源线、地线等问题,及检查PCB图时所用的高亮度显示的方法。
关键词:温度采集 PID控制上下位机通信
Abstract :
This study will discuss how to gather three temperature data .This system use the temperature sensor of 7109 .it could gather and keep temperature data . puter sets temperature municating with gathering the temperature date ,it can display the data on puter . In pletion of the thesis, I mainly carry through hereinafter job:
Analyze the requirement of the system, and design the whole structure of the system.
Subdivide the whole, and design each module in particular
Protract schematic plot and PCB plot, and crank out experiment board
Write software procedure according to hardware circuit
In debugging moment, debug each software and hardware module, write testing procedure, validate the usability of the system, and finally crank out the system sample
This thesis will discuss the part of long-distance temperature ‘s gathering and contron. The software is set by three part : part of temperature gatering pid contron munication puter and scm
In addition, in the text, it also introduces the tools used in protracting schematic plot and PCB plot and the problems required attendant. Such as, power supply wire、ground wire and so on, and the way of highlight display in examining the PCB plot.
I hope everybody can present criticisms and point out mistakes so that I can correct in the thesis, hereon, thank especially the tutor who help me plish my graduate design.
Keywords: temperature gather PID munication puer and scm
