Development Of Embedded System Based On Linux/QT

In today’s society, using the Linux graphical interface QT programming tools to write embedded graphic interface management software, serial communication, data processing, curve drawing,3G network communication and video surveillance operation has been more common in the ARM terminal. In this paper, the embedded system research in the learning process to complete the design of black carbon aerosol concentration monitoring embedded management system and reservoir intelligent information acquisition of ARM terminal management system two QT graphical interface programming, embedded system on Linux QT made analysis and research.According to the software design requirement of black carbon aerosol concentration monitoring system for measuring principle and the reservoir of intelligent information acquisition system, the choice of object-oriented application development tool QT to compile the graphical user interface in embedded environment, using SQlite3as the background database, using the virtual machine environment Linux Fedora14versions for cross platform, to modular program design as the main ideas, combined with the C/C++programming language and QT programming and QT programming characteristic signal and slot mechanism, research and design of black carbon aerosol concentration monitoring embedded system management software and the reservoir of intelligent information acquisition system management software.Through the hardware and software of the black carbon aerosol embedded management system and reservoir intelligent information acquisition system debugging, the black carbon aerosol concentration real-time data reading, curve drawing and database access and query functions, and also to control the operation of each function of the black carbon aerosol concentration hardware monitoring system module can be; reservoir parameter display of all kinds of sensors in the ARM terminal, the preservation of historical data, video monitoring, data exchange and remote control functions of3G remote communication.The research of atmospheric black carbon aerosol concentration monitoring of embedded intelligent information management systems and reservoirs collection terminal management system with two ARM QT GUI programming embedded management system. Analysis of the development methodology Linux/QT embedded management system software, summed up the QT embedded platform based graphical interface management system software development and design ideas and methods of implementation.
