基于μC/OS-Ⅲ的按键算法在掘进机中的应用

Application of Key-Algorithm Method Based on μC/OS-Ⅲ in Roadheader

针对掘进机在现场使用中遇到按键单击、双击、长按和两个按键同时按下的情况,提出了基于μC/OS-Ⅲ(微型C语言编写操作系统,第3版)操作系统的多任务设计方法。经过测试,可以检测到按键的单次按下、双击、长按,也可以检测到两个按键同时按下。系统运行情况良好,满足掘进机的使用要求。

For the situation of roadheader in the field encounter short-click key, long-click key, double-click k and press two keys at the same time, presents a multi-tasking design method based on μC/OS-Ⅲ （Micro- Sprache system-Ⅲ） operating system. By test, this system can detect short-click key, long-click key, double-cli key and press two keys at the same time. This system is running in good condition and meets the requirements roadheaders.
