Abstract: The paper presents how a real-time operating system, VxWorks, is applied to radio communication field. It realizes real-time control of signal command board by utilizing the excellent real-time performance and multi-task scheduling technology of VxWorks, and gives the detailed software design and development process for real-time control system in VxWorks. In the end, it gives the performance analysis and compares with the last single-task control system on the result of performance measurement; it shows that the excellent of utilizing the Vxworks to radio communication field.
