摘要/Abstract

摘要： 串行采集卡由于采集原理本身的原因，会导致多通道采集时各通道数据时间戳不一致．为解决此问题，文中提出一种基于时间戳补偿的串行采集卡性能提升技术，建立了多通道时间戳补偿算法数学模型，推导出了多通道时间戳补偿公式以及多通道同步采集值估算公式．该方法能在不改变采集卡的情况下，通过软件处理算法使各通道数据同步性能得到提高，获得相当于并行采集卡获得的数据．实例计算与应用表明，基于时间戳补偿的串行采集卡性能提升技术对于同步实时采集场合具有实用、有效的特点．

关键词: 串行采集卡, 多通道, 时间戳, 补偿算法

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
