【摘要】：伴随着我国城市化的快速发展,城市内涝问题逐渐凸显出来,特别是近几年,各大城市频繁出现城市内涝灾害,给人们的生活财产带来损失。随着电子技术和计算机网络技术的飞速发展,设计基于网络技术的远程排水监测系统,实现对内涝区域数据的实时监测,从而采取及时有效的应对措施,最大限度的保证人们的生活财产不受损失,具有非常大的意义。 本论文实现了基于嵌入式Web服务器的远程排水监测系统,系统由数据采集与处理单元、网络数据传输单元、uC/OS-Ⅱ操作系统单元、嵌入式TCP/IP协议栈单元、嵌入式WEB服务器单元和数据服务器单元等组成,具有以下基本功能： 第一,数据采集功能,利用ADC模数转换模块,将雨量、压力等模拟数据转换为易于传输和存储的数字量,在对ADC采集值进行处理过程中,引入了过采样技术和均值滤波技术,将ADC采样精度提高到12位,改善了ADC采集值的准确性。 第二,具有以太网接口,支持TCP/IP协议,可将系统连入互联网,实现远程数据传输和系统管理等功能。 第三,具备B/S架构服务器功能,支持Web浏览器快速实时查看系统数据,或对系统进行实时的管理。Web服务器采用类似中断的信号量技术和查表法解析用户操作逻辑技术,提高了系统检测和处理数据请求的速度,减少了系统响应时间。 第四,具备C/S架构服务器功能,支持远程数据传输,将系统数据传输至远程客户端,进行更深入的分析处理,设计了客户端和服务器端数据传输协议,提高了数据传输的效率。 第五,设计了独立的数据维护模块,方便数据管理、更新和搜索操作,提高了数据安全性和可扩展性,有效缩短客户端向服务器端请求数据的等待时间。 论文设计实现了基于网络交换芯片88E6083驱动程序、A/D数据采集程序、串口通信模块、uC/OS-Ⅱ操作系统移植、嵌入式TCP/IP协议栈、Socket接口、嵌入式WEB服务器和数据服务器等。在提高系统响应速度和ADC数据精度方面进行了学习和研究,具有一定的实践和研究价值。该排水监控系统具有成本低、稳定性好和实时性高的特点,具有很广泛的应用前景。
[Abstract]:Along with the rapid development of urbanization in China , the problem of urban waterlogging becomes more and more obvious , especially in recent years , the urban waterlogging disaster has frequently occurred in major cities . With the rapid development of electronic technology and computer network technology , the remote drainage monitoring system based on the network technology is designed to realize the real - time monitoring of the data in the area of waterlogging , so as to take prompt and effective response measures to ensure that people ' s life property is not lost and has great significance .

The system consists of data acquisition and processing unit , network data transmission unit , uC / OS - II operating system unit , embedded TCP / IP protocol stack unit , embedded WEB server unit and data server unit , and has the following basic functions :

First , the data acquisition function is used to convert analog data such as rain , pressure and the like into a digital quantity which is easy to transmit and store by using an ADC analog - to - digital conversion module . In the process of processing the ADC acquisition value , an oversampling technology and an average filtering technique are introduced , so that the sampling precision of the ADC is improved to 12 bits , and the accuracy of the ADC acquisition value is improved .

Second , it has Ethernet interface , supports TCP / IP protocol , can connect the system to the Internet , realize remote data transmission and system management functions .

Third , it has the function of B / S architecture server , supports web browser to view system data in real time , or manage the system in real time . Web server uses semaphore technique and look - up method similar to interrupt to resolve user ' s operating logic technology , improves system detection and processing speed of data request , and reduces system response time .

Fourthly , it has the function of C / S architecture server , supports remote data transmission , transfers the system data to remote client , carries on more in - depth analysis processing , designs client and server side data transmission protocol , and improves the efficiency of data transmission .

Fifth , the independent data maintenance module is designed , which facilitates data management , update and search operation , improves the data security and the scalability , and effectively shortens the waiting time of the client to request data to the server side .

The paper designs a network - switched chip 88E6083 driver , A / D data acquisition program , a serial communication module , a uC / OS - 鈪，
