针对由计算机控制的仪器工作状态监测问题,提出一种基于计算机串口的数据流监测方案,采用纯软件的方式,规避硬件监测的风险,通过截获串口与仪器设备之间的数据流进行模式匹配,实现仪器状态监测.为提高数据流变化的检测效率,采用加权的核拟合密度估计算法代替传统的M-核估计方法,降低系统资源的占用率.

As for status monitoring for computer-controlled instruments, a monitoring scheme for data stream based on computer serial interface is proposed, which avoids the risk form hardware monitoring by pure software technology and judges instrument status by interception and pattern matching data stream between instruments and serial interface. In order to improve the detection efficiency of data stream and reduce the occupancy rate of resources, weighted core-fitting density approximation approach is chosen instead of traditional M-core.
