R&D And Application Of Embedded Network Controller

In the field of industrial control, the networking and informational revolution has been carried in our country, the traditional industrial control field is also continuously improved to adapt to this change during the development of industrial control network, so we need develop an embedded industrial network controller with Ethernet and field network function, to realize the seamless connection of the Internet/Intranet in traditional industrial equipment and the enterprise information network, that will be interconnected lower field control network and enterprise information network, which make the signal collection, transmission and the function of TCP/IP communication integrate into one, thus the system network is become more easily, the data transmit become quicker, only through the Web browser (EI) can monitor the real-time situation of the underlying equipment, some solutions is provided on embedded network controller in many areas of environmental monitor, petrochemical etc., the technical foundation certain and implementation platform is established, to enhance our networking and informational industry control have a wide application prospect.After collecting and related documents, made the die casting machine as the research object, embedded networking controller on the die casting workshop is designed. The main contents of the development follow:1. The overall design of the embedded network controllerFrom the point of functions of die-casting workshop, the main functions of the design has been discussed and analyzed, and then according to the functions the system structure of the embedded network controller has been designed.2. The hardware design of the embedded network controllerAccording to the system structure of embedded network controller, the hardware was designed part by part, including the design of the central controller which is use the STM32chip as the core, data acquisition, output controller, serial communication, network interface etc... 3. The software design of the embedded network controllerBuild the software development platform by transplant Embedded system of uC/OS-Ⅱ, the control system software was to designed according the remote monitoring function of the die casting machine, including data collection, input processing, order processing and communication program.4. The implementation and debugging of the embedded network controllerSimple introduced how to debug the embedded network controller system, achieved the remote monitoring of die casting machine through the dynamic Webpage.Finally, summarize the full text, and illustrates the main research achievements and prospect.
