MEASUREMENT ACCURACY OF NON-CONTACT DISCHARGE MEASUREMENT METHOD USING RIVER MONITORING MOVIE AND DEVELOPMENT OF QUASI REAL TIME MEASUREMENT SYSTEM

With the rapid development of aviation technology, the performance of aero-engine continues to increase in China. However, Chinese Aero-engine lubricating oil real-time measurement technology is not mature, active airplane almost have no Aero-engine lubricating oil real-time measurement system, It requires further in-depth study.By research on Aero-engine lubricating oil measurement technology. First, it outlined the method and principles of measurement, and based on UG Open the analysis of Aero-engine lubricating oil system was developed. Through which an analysis of the model of Aero-engine lubricating oil, the spatial databases about sensor depth of immersion oil, aircraft attitude and fuel volume were built.,which can provide the data for the subsequent lubricating real-time oil measuring analysis .

Real Time Measurement

According to Doppler effect of satellite on the time synchronization technology between satellite and the ground station, a real-time measurement method of Doppler is proposed based on GPS carrier signals. Using Doppler observations from GPS receiver, the method can real-timely measure Doppler frequency shift of GPS including dynamic Doppler and media Doppler whose error can be timely modified in the receiver end. Simulation results show that the frequency shift caused by dynamic Doppler, a main influencing factor in the course of transmission of time-frequency signal by GPS satellite, is between plus or minus several thousands Hz. Comparing to traditional measurement method of Doppler, the method makes it possible to fast track phase of signal in large dynamic range in synchronous technology.
