为实现基于嵌入式Linux系统的ARM11手持监控器与下位机之间的串口通信,在基于ARM1176JZF-S核的ARM11开发板上移植Linux操作系统,搭建嵌入式QT应用平台。利用QT可视化的图形界面及丰富的图形库,设计并制作手持监控器图形界面。根据Linux下串口通信的应用层协议,最终实现了下位机的运动状态数据在QT界面上的实时显示。该方法简单、可靠、便于实际工程应用,解除了PC机对下位机进行远程数据监控携带不方便的问题。由于Linux系统和QT都有较强的可移植性,该方法在远程手持监控设备中将有广泛的应用前景。
為實現基于嵌入式Linux繫統的ARM11手持鑑控器與下位機之間的串口通信,在基于ARM1176JZF-S覈的ARM11開髮闆上移植Linux操作繫統,搭建嵌入式QT應用平檯。利用QT可視化的圖形界麵及豐富的圖形庫,設計併製作手持鑑控器圖形界麵。根據Linux下串口通信的應用層協議,最終實現瞭下位機的運動狀態數據在QT界麵上的實時顯示。該方法簡單、可靠、便于實際工程應用,解除瞭PC機對下位機進行遠程數據鑑控攜帶不方便的問題。由于Linux繫統和QT都有較彊的可移植性,該方法在遠程手持鑑控設備中將有廣汎的應用前景。

To realize the serial communication between the lower position machine and the ARM11 handheld monitor based on the Linux operation system,the Linux system was transplanted to the ARM11 development board with ARM1176JZF-S ker-nel,and the QT application platform was set up to design and produce the graphical interface by using QT visual graphic inter-face and rich graphics library. The real-time display of state data of the lower position machine is realized on the QT interface ac-cording to the serial communication application layer protocol under the Linux system. The method is simple,reliable and easy to use in real engineering,which has solved the problem that it is difficult for PC to execute the remote data monitoring to the lower position machine. The method will have wide application prospects in the handheld remote monitoring due to the strong portability of both Linux system and QT software.
