Research And Implementation Of Embedded Browser For Nc Based On ARM

For web-based applications for industrial control, embedded browser is an important part, especially in CNC field. With the embedded system and the rapid development of computer network technology, used in the field of numerical control technology embedded browser must be constantly updated to adapt to the application. Most of the current type of browser and commercialization of WinCE-based is expensive and difficult to maintain, so it is very necessary that the research for open-source browser, and on this basis to achieve a flexible, open the embedded browser. In this paper, embedded in the browser of a number of key technologies, specific research contents include the following:1. There is analysis of browser based on ARM related technologies, for existing standards, protocols, embedded operating system and open-source browser options and cutting, it lay the foundation for follow-up design.2. It design an embedded browser program. Open source browser based on existing research and learn, from the browser function key to set the level and design a complete browser based on ARM, analyzed the browsers used by multiple threads and interface technology, and in real time and portability improvements, proposed a number of programs to further improve.3. It gives a browser based on ARM and NC implementation of existing development platform for the actual situation, the results of this study will be applied to real ARM development board, using C / C++ language and Linux operating system library functions such as development tool system, the main module, the data structure, implementation processes, and interface definitions, especially the UI module of QT-based graphics library and MiniGUI library implementation are described in detail, finally completed a NC browser prototype based on ARM.
