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。 关键词 游程编码 数据压缩 存贮深度 Abstract: 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 high-speed sampling and huge-memory capacity,it is practical and easy to realize. Keywords: RLC(Run Length Code) data compression memory depth
