UAV Telemetry Data Acquisition System Based on Virtual Instrument Technology

摘要

To realize the real time monitoring of UAV (Unmanned Aerial Vehicle) telemetering data, with virtual instrument (VI) development software--Lab Windows/CVI establishment virtual telemetry acquisition system. According to the telemetering data stream of PCM system, with VC++ carry out multithread acquisition, make gather thread in the form of DLL built-in Lab Windows/CVI; have realized the reliable acquisition under data burst transmission pattern. Use the database of Power Builder to managed the acquisition data, establishes CVI and PB database through ODBC interface using SQL language to connect, have realized data share.
