【摘要】 结合飞机静压自动测量系统的研制,提出了一种利用双串行通信接口和多进程技术在运动状态下实时采集测量数据的方法,即采用双串口来实现测量数据的实时采集。利用ActiveX EXE部件开发状态监测进程,用异步事件的方式通知主进程采集数据。应用结果证明,该通信方法有效可靠,满足了系统的实时性要求。更多还原

【Abstract】 A novel dynamic real-time data acquisition method based on double serial communication ports and multi-process technique is proposed.Double serial communication ports are used to realize real-time data acquisition.The state monitoring process is developed by using ActiveX EXE,and data acquisition is performed by the main process which is informed by asynchronous events.Applications show that the proposed method is feasible,reliable and has good real-timeness.更多还原
