Research And Application Of Remote Monitoring And Control System Based On Embedded Web Server

The development of network technology,making each industry is more and more inseparable through the Internet and all kinds of network equipment,which also makes the embedded web monitoring system be used more and more extensively in embedded applications.The access of industrial equipment to the Internet can not only facilitate the monitoring of staff to view,but also can improve the efficiency of production play a certain role in promoting.In order to facilitate the monitoring of controlled equipment,the graphical web interface can be used to achieve friendly user interaction.To achieve the function of network connection service,system can be transplanted the operate system with TCP/IP protocol while its processor has rich hardware resource.To the simple application system which has micro-processor with relatively less hardware resource,it can only be transplanted simplify TCP/IP protocol to achieve the function of network services.A study of the monitoring of coal mine environment parameters is described in the thesis,in which the STM32F407 processor is used to complete the task of network connectivity and services.STM32F407 as the core processor is used to achieve network services by the internal HTTP protocol.to complete the task of the physical connection of the network by the WIFI part which is integrated in STM32F407.AT first,the basic embedded web services and its design technology are introduced,and then the system is designed in detail including system hardware structure,connection circuit,software program and protocol transplantation.The transplanting process of the web server without operate system is also described in detail.At last,In the application of remote monitoring system,by using CGI and SSI technology in web server,the function of dynamic interaction between the user and the controlled device is realized through the web browser.
