【摘要】：随着计算机技术及嵌入式技术的高速发展，人们需要一种新的更加灵活的温度监控系统:这种系统能够应用在一些不适合人接近的环境下对环境温度进行远距离监测;并且可以利用因特网，随时通过计算机的网页实时观测环境温度的变化。本论文研究了目前远程温度监控系统的发展现状，结合目前远程温度监控系统的不足，利用嵌入式系统技术和计算机技术实现了一种基于因特网的远程温度监控系统，用户可通过因特网利用浏览器登陆嵌入式Web服务器实现对远程现场温度数据监控。本文研究的整个系统以8位微控制器为主处理器，通过程序直接驱动网络控制器ENC28J60，通过SPI协议传输的EEPROM做为存储网页的存储设备。并可通过液晶显示器显示系统IP及传送的数据等相关信息，还可以用PC机上的超级终端通过串口对系统的IP，网关，子网掩码等进行配置。完成后的终端支持HTTP、TCP、UDP、FTP等常用网络协议，支持PING命令并可给予响应，可以通过IE直接浏览存放在存储器中的网页，并可以能过网页上的按钮控件来控制远程的开关量，，从而实现远程数据采集和远程控制等功能。本设计完成了对系统的需求分析，各模块的功能分析，硬件应用电路的设计及实现，网络控制器驱动程序的编写，相关网络协议的在嵌入式系统上的移植，以及整个系统的联机调试及测试等工作。测试结果表明本设计完成了远程温度监控的基本功能，证明了该系统的可行性，达到了预期目标。
[Abstract]:With the rapid development of computer technology and embedded technology. There is a need for a new and more flexible temperature monitoring system that can be used for remote monitoring of environmental temperatures in unsuitable environments; And can use the Internet, at any time through the computer's web page real-time observation of environmental temperature changes. This paper studies the current development of remote temperature monitoring system, combined with the shortcomings of the current remote temperature monitoring system. A remote temperature monitoring system based on Internet is realized by using embedded system technology and computer technology. Users can use the Internet browser to log on to embedded Web server to realize remote monitoring of temperature data. The whole system studied in this paper is mainly composed of 8-bit microcontroller, which drives the network controller ENC28J60 directly by program. The EEPROM transmitted by SPI protocol is used as the storage device for storing web pages. It can display the system IP and the transmitted data through liquid crystal display (LCD). It is also possible to configure the IPs, gateways, subnet masks and so on by the PC super terminal through serial port. The completed terminal supports common network protocols such as HTTP / TCP / UDP / FTP and so on. Support PING command and can give a response, you can directly browse through IE stored in the memory of the web page, and can pass through the button control on the web page to control the remote switch. In order to achieve remote data acquisition and remote control and other functions. This design has completed the system demand analysis, each module function analysis, the hardware application circuit design and the realization, the network controller driver programming, the correlation network protocol transplant on the embedded system. The test results show that the design has completed the basic function of remote temperature monitoring, proved the feasibility of the system and achieved the expected goal.
