High-Speed Acquisition and Simulation of Multi-Dimensional Data under Multi-Port Parallel Communication
In the process of multi-port parallel sampling,the error caused by a mismatch among different input channels can lead to inaccurate data acquisition,and a large amount of redundant data also increases the burden of data transmission.To improve the efficiency of data acquisition,this paper proposed a high-speed acquisition method for multi-dimensional data in multi-port communication.Firstly,the ideal value of multi-dimensional data acquisition was determined.Then,the signal-to-noise ratio environment of multi-port communication was analyzed.At the same time,a general interface was selected to ensure communication compatibility and stable analog-to-digital converter performance.In order to reduce the mismatch error of multi-port parallel sampling,a time-interleaved parallel acqui-sition strategy was used to debug various errors of the port,thus reducing the signal-to-noise ratio of the channel.Based on real-time judgment of the time required for data acquisition,the data acquisition error function was recon-structed.According to the acquisition interval and fuzzy rules,the effective distance was adjusted.Finally,redundant data was determined and deleted.Thus,the high-speed acquisition of multi-dimensional data was achieved.Experi-ment results prove that the method can achieve high-speed acquisition while ensuring data integrity and accuracy.It is less affected by noise during the acquisition.
