A Timing Sequence Feature Fusion Algorithm for Multi-module Data Acquisition System

Electromagnetic interference and signal crosstalk between multiple signal channels can affect the signal transmission of multi-module data acquisition system. When the timing signal in the data acquisition system is disturbed, the timing signal could be triggered by mistakes, causing the acquisition unit to collect the wrong data. However, in order to ensure the accuracy of the digital signal, the hardware anti-interference measures are limited. This paper proposes a timing fusion method for multi-module acquisition unit acquisition systems to filter out erroneous data collected due to timing errors. The method applies a multi-node data fusion model and timing sequence feature model to the acquisition system, and uses the state machine method to analyze the timing sequence status at each node.Highly accurate data can be acquired by incorporating the method in the acquisition system and only a small amount of calculation is required.
