Design of flight data recorder based on ARM microcontroller

Abstract

To record the flight data of unmanned helicopter in real time, and for the convenience of subsequent analysis of the helicopter′s flight state and mathematical modeling, in this paper, a data recorder with the features of good practicability, generality and convenient to transplantation is designed with software and hardware solution. This solution is designed with ARM microcontroller combined with SD card and the file system, and commonly used communication interfaces are added to connect with different devices using different communication protocols. By actual running tests, the flight data can be well stored in the file set up before, and provides the convenience for subsequent data analysis, curve drawing and so on. Also, it has certain significance for popularization and practical value.
