Design Of Data Collection System Based On WEB Server

Embedded WEB server technology is a product of the combination of embedded computer technology and Internet technology. After embedded systems is connected to the Internet, the remote measurement, the remote control, the remote diagnosis and the remote maintenance became much easier. Users can monitor and manage remote device through a browser. Building an Embedded System Platform is one of the key research directions.STM32 ARM-based embedded network hardware platforms is constructed in this paper, while the migration issues of theμC/OS-Ⅱand the TCP/IP protocol stack on the platform is solved. The corresponding embedded networking software platform is builded. Hardware, The STM32F107RC chip based on Cortex-M3 is selected as the core processor of the embedded WEB server, which integrated 10/100Mbps Ethernet MAC core, high-speed direct memory access function (DMA) and 4KB SRAM, and meet the IEEE1588 standard. The high-performance and miniature embedded network hardware platform can be easily builded. Software, The open-source real-time operating systemμC/OS-Ⅱis used as the software platform, while the TCP/IP protocol stack LWIP that open source and development for embedded systems is migrated. The embedded WEB server is designed, and the two key technologies of the Embedded WEB server, the Hypertext Transfer Protocol (HTTP) and the Common Gateway Interface (CGI) is implemented.Finally, the data of the romote device is acquired and processed through the embedded WEB server, and which is published to the Internet through it. The embedded WEB server is accessed through the IE browser, and the collected analog data is acquired, while the remote device's operating status can be controlled. The system is reliable and performance stable, the existing industrial equipment is reconstructed, achieving the low-cost and networked.
