摘要
介绍了在QNX实时操作系统下分布式采集控制程序的编写。现场机器负责数据采集存储,并按照预设的参数进行控制。控制室机器负责参数设置与波形的显示,同时负责在控制室远程启动现场机器程序并返回运行的状态,以便在现场机器程序出现异常情况下采取相应的措施。经测试,系统的实时性和可靠性很好地满足了EAST装置LHCD系统单管测试的需要。
Distributed acquisition and control system based on QNX are described. The master computer is used to acquire and control the power of microwave according to the parameters given by slave computer. The slave computer sends the controlling parameters to the master and display the waveform. The slave computer also can start and stop the master program remotely. After some tests of LHCD system on EAST, the real time property and reliability of the system are satisfactory very well.
