Abstract: In accordance with existing problems of data transmission and network communication of distributed data acquisition system, a DataSocket communication model based on the principle of asynchronous parallel algorithm is presented. According to the two indices of speedup ratio and parallel efficiency in the communication model, asynchronous parallel algorithm is optimized, and the optimized system is applied to a diesel engine digital test system. Experimental result shows that not only the communication overhead problem in the process of data real-time transportation is solved, but also the data transmission efficiency of the distributed data acquisition system is improved effectively.
