Abstract:

In designing the data acquisition program, it is found that the design pattern of program has a great influence on the efficiency of data acquisition and processing. As for it, in this paper, LabVIEW producer / consumer design pattern is introduced and applied to the design of multi-task audio signal acquisition system. In this design, the audio parameter setting and data acquisition and processing are allocated to two parallel loops, and the parameters of the audio signal are set in the producer loop while the data collection and processing are done in the consumer loop, which greatly improves the efficiency of data acquisition and processing, and improves the readability, expansibility, maintainability and reusability of the program.

Key words: LabVIEW, producer consumer pattern, data acquisition, queue
