摘　　要：铁路车站信号计算机联锁控制系统是实时、多任务、安全苛求的计算机控制系统。分析DOS和Windows环境联锁控制软件设计存在的问题,结合VxWorks操作系统的特点,研究基于VxWorks实现联锁控制的可行性,在此基础上提出了一种VxWorks环境下设计联锁软件的方法,并进行了详细的系统设计。针对一个实际站场的编码测试结果表明,在VxWorks环境下更易于满足联锁软件对实时性、多任务调度的设计要求,并有利于提高系统的安全性。Computer Interlocking Control System（CIS） applied in railway station signaling was a real-time, multi-task and safety-critical computer control system. It was analysed the problems of interlocking control software design based on DOS and Windows, in accordance with the characteristics of VxWorks, researched the feasibility of implementing interlocking control based on VxWorks, presented a design method of interlocking control software under VxWorks, and gave detailed design process. The control software based on VxWorks was coded and tested with a real station, the result indicated that it was much easier to satisfy the real-time, multi-task demand for interlocking control software and more propitious to improve the System security.
