| Abstract: |
| A mobile meteorological observation system was developed based on NI virtual instrumentation, which can be used in ships or any other mobile offshore platforms to measure real wind velocity and monitor some other meteorological parameters simultaneously, and has been applied in ocean research. It took advantage of inherent multithreading technology provided by parallel data flow programming architecture of NI LabVIEW to implement parallel access to various data acquistition devices through serial ports, and integrated software, hardware, peripheral devices and PC very effectively to raise the developing efficiency and improve the measurement. For the sake of equipment compatibiligy, the system was designed to support NMEA 0183 communication standard. Any GPS, compass, meteorological equipments compatible with NMEA 1083 can, therefore, be connected as data input device into the system. Besides real time data logging function, the system can also display the real time trend of measurements, and is therefore of great assistance for ocean meteorological research and weather forecast. |
