摘要
针对分布式数据采集在数据传输和网络通信等方面存在的问题,给出一种基于异步并行算法的DataSocket通信模型,根据该通信模型中的加速比和并行效率2个指标对异步并行算法进行优化,将优化后的模型应用到某柴油机数字化实验系统中。实验结果表明,优化后的模型能解决数据实时传输中通信开销大的问题,提高了分布式数据采集系统中的数据传输效率。
In accordance with existing problems of data transmission and network communication of distributed data acquisition system, a DamSocket 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 imoroved effectively
