| In the field of factory automation system,due to the intrinsic indeterminacy of information transfer,ethernet was once rejected outside the door of industry control net for a long time.In recent years,with the development of ethernet technology,some critical technicality was resolved.Ethernet began to infiltrate to the layer of process control and field facilities which were once monopolized by FCS.It makes the whole factory network become highly unified,open and transparent.As a critical application area of industry ethernet,the monitor system based on Web makes the customer can monitor the field facilities using custom Web browser by embedding Web server in field facilities.The custom 8/16 bits monolithic processor cannot meet the demand of monitor system based on Web.on the other hand,with the development of semiconductor industry ,the price of 32 bits embedded microprocessor dropped quickly , and the technology of embedded Linux came.The custor factor which restrict the fullscale application of embedded technology disappeared.Introducing embedded Linux into the monitor system based on Web became a perfect solution.This article had the embedded microprocessor S3C44B0X as the core of hardware platform,choosed the excellent embedded linux OS uClinux as software platform and Boa as embedded Web server to build monitor system... |
