摘　　要：介绍了VxWorks实时操作系统实时性和多任务环境的特性。在分析了天线控制系统基本原理的基础上,提出天线控制系统的各个任务模块的划分原则,介绍了各个任务的优先级别和触发方式,提出了各个任务间的通信手段与同步方法。此外,还给出了在PC104嵌入式计算机上,应用VxWorks实时操作系统成功开发天线控制系统软件的实例。This paper introduces the characteristics of real-time operation system （RTOS） and multi-task environment about VxWorks. Based on the analysis of Antenna Control System theory , it provides the principles to decompose the system into tasks , and intro- duces the tasks＂ priorities and starting-up method . In the meanwhile, it brings forward the method of communication and synchro- nization between the tasks. At last, it offers an instance of Antenna Control System software developed by RTOS VxWorks based on the embedded computer PC104.
