Design and implementation of control system software based on VxWorks multi-tasks

Abstract

This article fist introduces an embedded real-time operating system VxWorks and its multi-tasks mechanism. Combining the requirements of the control system which needs to complete the engineering tasks and multi-task, real-time, it gives serial port driver and design of application layer. It proposes a multiple-task model and a method of task-scheduling. It also offers the detailed artifice of measurement under the pc104 hardware, and the results showed that multi-task to meet the multi-task and real-time. It has a good practical application.
