  • In order to obtain the data corresponding to certain condition or status from mass test data quickly and accurately, the problems existing in conventional time-sequence search methods were analyzed, and a fast search approach for multi-channel mass data was proposed based on optimal entropic matching. In this approach, the conventional time matching is replaced by status matching. The approach depends mainly on entropy testing to need few parameters, have less reliance on neighborhood time and largely reduce the error caused by time synchronization between different channels. Furthermore, it has a big search scale and a fast search speed. The result shows that in certain condition, the search speed can be increased by thousands of times with an improved matching precision, and the relative error of every main parameter is less than 0.05.
