Abstract

Restricted by the serial acquisition principle of serial acquisition card，the time stamps of each channel are inconsistent during multi-channel acquisition． To solve this problem，a performance improvement technology for serial acquisition card based on time stamp compensation was proposed and a mathematical model of multi-channel time stamp compensation algorithm was established． Formulas of multi-channel time stamp compensation and multi-channel synchronous acquisition value estimation were derived． The method can improve the data synchronization performance of each channel through the software processing algorithm without changing the serial acquisition card，and obtain the data equivalent to the parallel acquisition card． The example calculation and application show that the performance improvement technology for serial acquisition card based on time stamp compensation is practical and effective for synchronous realtime acquisition． 

Key words： serial acquisition card; multi-channel; time stamp; compensation algorithm
