摘要
The embedded multi-task real-time operating system is a method to improve the dynamic characteristic of arc welding inverter. A digital arc welding power supply was designed, ARM (advanced reduced instruction set computer machine) as controller and μC/OS-II as operating system. Welding processing was divided into 15 tasks with the principle that major task enjoyed more priority. Two semaphores were introduced to avoid simultaneous-sharing on the same source from several tasks. To accelerate the major task processing speed, data would be transferred to the minor tasks in the form of message box.
