摘　　要：用户访问可编程逻辑器件时,由于无法直接访问系统数据,导致器件数据与用户数据之间出现冲突,为此设计了可编程逻辑器件间的大数据自适应跟踪系统。构建自适应跟踪总体结构,同步本地参考信号和外部输入信号。配置时钟电路,计算时钟上升和下降过渡时间,避免电路供电杂波干扰。系统采用非侵入式设计自适应跟踪机制,结合Mean Shift跟踪算法计算跟踪矢量,确定可编程逻辑器件间数据的匹配位置。利用Kalman滤波器对数据进行滤波处理,获取大数据自适应跟踪结果。由实验结果可知,该系统噪声信号变化范围是40~100 dB,与实际变化范围一致。同步信号变化范围是35~100 dB,其中,在5~8 s时同步信号变化范围与实际变化范围不一致,其余均一致,具有精准跟踪效果。When users access programmable logic devices,they cannot directly access the system data,resulting in conflicts between device data and user data.Therefore,a large data adaptive tracking system between programmable logic devices is designed.The overall structure of adaptive tracking is constructed to synchronize the local reference signal and external input signal.Configure the clock circuit,calculate the clock rise and fall transition time,and avoid circuit power supply clutter interference.The system adopts a non-intrusive design adaptive tracking mechanism,and calculates the tracking vector in combination with the Mean Shift tracking algorithm to determine the matching position of data between programmable logic devices.The Kalman filter is used to filter the data and obtain the large data adaptive tracking results.According to the experimental results,the variation range of the system noise signal is 40~100 dB,which is consistent with the actual variation range.The change range of synchronous signal is 35~100 dB,of which the change range of synchronous signal is inconsistent with the actual change range at 5~8 s,and the rest are consistent,with accurate tracking effect.
