利用扩展游程编码数据采集技术优化高速数据采集系统

Optimization of High Speed Data Acquisition System by the Utilization on an Extended Rlc Data Acquisition Technology

针对被检测信号具有长时间域、瞬变特征波形的时域位置不确定等特点,提出一种扩展游程编码数据采集方法。描述了系统的硬件、软件设计。该方法解决了高速采样与大容量数据存贮之间的矛盾,具有较高的实用价值。

This paper proposes an extended RLC （Run Length Code） deta acquisition method. The detected signal has the feature of long time lasting and transienting characteristic wareforms. The designs of the systems hard ware and software are desaribed.This method solves thec ontradiction between highspeed sampling and huge-memory capacity,it is practical and easy to realize.
