航空发动机滑油泵试验台测控系统设计与实现

摘要

According to the function and requirement of measurement and control system of aero - engine lubrication system test - bed, a new measurement and control system for lubricating oil pump test - bed was designed based on PLC hardware device and iFIX software. Active X technology was used to develop special control library applied to this system. Moreover, FIR filter was designed to improve the data accuracy. The application shows the system runs stably, operates easily and has friendly interface. It has achieved design requirements.%根据航空发动机滑油泵试验台的功能及要求,设计了基于PLC硬件系统和iFIX监控软件的滑油泵试验台测控系统;应用Active X控件开发技术,在Visual Basic 6.0环境下开发适用于本系统的控件库;同时引入FIR数字滤波器,对采集的信号进行滤波,以提高数据的准确度;试验台的调试运行表明,该系统可靠、稳定,操作简便,达到了设计要求.
