The traditional data acquisition system can’t meet with the demand of instantaneity and flexibility in the engineering application. In order to get the goal of data real-time acquisitioning, storing and processing, this system takes the queue as a data buffer and controls the data storage by using event structure. Spectrum analyzing was performed in the NDB signals stored and the frequencies, the amplitudes and the phases were also picked up. Thus, the measurement of navigation parameters was finished. As was demonstrated in the results, the integration of data real-time acquisitioning, storing and processing was finished successfully. So the efficiency of data acquisition was improved, and the resource was shared. The system was successfully applied in the lab research.
