The Research Of Remote Monitoring Lab System Based On Embedded Linux

With the rapid development of embedded technology and the rising of embeddedinternet, transplanting OS to ARM is a trade in remote monitoring system, realizingremote monitoring through the embedded web server. With the rapid development ofinternet,embedded device insertting internet is becoming a trade.Client can monitor theremote device through the internet.And this monitoring way is becoming a trade inindustry control.This paper adopts ARM kernel S3C2410as its CPU.The web server program runsunder the embedded Linux system platform,using ZC301camara to gather image andstoring image data after compression.The boa web server wait the client using thebrowser sent the request to visit in monitoring environment.Server CGI procedures dealwith the request information and return results to the browser,realizing client browservisit home page through the net and receive image data.In this paper,through the research of remote monitoring system,embedded linux OSand image disposing technology transport through the web,designing a C/S remotemonitoring system based on embedded web server.It includes some modules:embeddedARM2410CPU controlling modules,sensor data handling modules,USB camera imagegather module and so on.Door control page can control door through the webpage; thesystem collect the data of temperature transducer and client can read temperature valueby server;ZC301camera and S3C2410constitute embedded video collect device,linkingnet host machine constitute video monitoring system.Firstly, we present three crucial technologies: GPS technology, GPRS technologyand embedded technology and specially describe the construction and data transmissionmode of GPRS network, pointing out the transmission advantage of GPRS networkcomparing with traditional GSM network. And the combination of commission andembedded technology is discussed. The composition structure and implementation stepsof the system are introduced based on it. At the same time, data transmissioncommunication protocol for on-board end and the monitoning center is given.In the part of the software system,it includes BootLoader based on ARM,theconfiguration of the embedded linux kernel,video collect software,temperature collectmodule program, the implementation of the embedded web server on ARM/linuxplatform,the embedded linux device drivers,CGI program,and the design of other applications,etc.Finally, with the actual research and development results, summarize and analyzethe characteristics of the system,forecast the next step of the design work in future.
