[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，
