Abstract:

In order to improve the current situation that currently the rice rate detection method is not so efficient as we expect, the ARM9 based software design solution of the head rice rate detector and its implementation are proposed. Based on image sensing technology, the head rice rate detector is used to automatically detect, compute and display the head rice rate. The Micro2240 development tool is used as the multimedia central control system .Based on the Qtopia software development platform, by using embedded data base Sqlite3, the design of the interface and the menu bar is accomplished. Besides, our work cooperates with the hardware through serial port communication and net port communication. Finally, the entire device works well. Test results are quite accurate, proving that the system is practical and high efficient.
