Software Design Of Wireless Order System Based On Qt And ARM

With the continuous raise of national product and living level,people now pay more and more attentions on better quality of catering consumption.While the wireless order system could provide more rapid,convenient,transparent and sanitary catering conditions,which are considered to be the key points for improvement of catering service quality and management efficiency.This subject designs the software of a wireless order system after analyzing the existing solutions of electronic order system.It focuses on universal and easy-use properties of the system's software,utilizes the existing development board YLSBC2440,and integrates WLAN,Linux and Qt,to construct a kind of wireless order system's terminal application and remote server software,which could be easily ported to various PDA and common PC.The main research contents are as follows:1.Constructing a platform for embedded Linux software development.Fistly establish the basic development environment including a cross-compiler and NFS server in Ubuntu7.10.Then install Qt,including Qt/X11 with qvfb tools, Qt/Embedded for both x86 and ARM editons,which are used to develop the order terminal application.2.Programming order terminal application.Use Qt Designer to sketch the terminal' graphical interface,and then write the codes,mainly including the realizations of core browser class and primary window class,besides internationalization and Chinese-support in the main program.Test the application on YLSBC2440 through NFS at last.3.Establishing server website.Utilize a normal x86 PC running XP OS as the Web server with IIS5.1 ASP website.Use DREAMWEAVER and ACCESS2003 to design the Web pages,including Access Management,Order Guide,Table Usage, Menu List,Order Submission and other functional pages.4.Debugging and publishing application.Utilize YLSBC2440's original kernel and root file system,adding configuration of wireless LAN support,and packing the order terminal application with its library files,the wireless NIC driver and wireless tools into the file system.Finally,transplant them into YLSBC2440 with WLAN connection and run the application.
