Real-time data acquisition system design and experimen for intelligent agricultural operations vehicle

A reliable and real-time data acquisition and transmission are required for circuit monitoring, on-line diagnostics, recording machine status and remoting machine when intelligent agriculture vehicle runs in the field. A Wi-Fi and SD based real-time data acquisition system was developed and applicated on an original electronic platform of lasercontrolled land leveler for paddy field. Data acquisition by the system could be transmitted timely to the computer through Wi-Fi module and stored in SD card in FAT file format. For verifying the reliability of this system, the real time data acquisition system was tested in paddy field. Experiment results showed that the data reflecting the performance of lasercontrolled land leveler could be recorded stably and accurately within a range of 100 meters in the open paddy field.
