The Design of Auto Measurement and Control System of Remote Data Recorder Based on Optical Fiber Transmission

摘要

This article designs an auto measurement and control system of the aircraft data recorder based on optical fiber transmission, this system can remote real-time monitor 5Km outside of the aircraft data recorder and read the data afterward. Data link transmission of the system uses 1B/12B encoding and decoding method in order to achieve DC-balance, which can guarantee that the remote command and data are correct. The whole system is not only the unique evaluation tool in design, production and experiment of the aircraft data recorder, but also the key to obtain the entire flight test data.
