分析了基于单片机的道口控制系统中存在的问题,结合VxWorks实时多任务操作系统的特点,提出了一种基于VxWorks环境下的道口控制软件的设计方法。针对实际道口的测试结果表明,在VxWorks环境下更容易满足复杂道口控制软件的实时性、多任务的调度要求,并且有利于提高道口的安全性。
Based on the characteristics of VxWorks real-time multitasking operating system, the paper presents a design method of crossing control software based on VxWorks environment. The test results for the actual crossing show that it is easier to meet the real-time and multi-tasking scheduling requirements of complex crossing control software in VxWorks environment and to improve the crossing safety.
