【摘要】 本文详细介绍了基于MCU+CPLD结构的故障行波测距装置的原理、结构及其特点。针对以往装置存在的测距精度较低和循环存储器死区问题,采用了MCU+CPLD的系统结构,用集成度较高的CPLD器件重新设计了高速采集控制器和时标标定模块,消除了循环存储器死区问题,也提高了测距精度。仿真结果也验证了设计的正确性。更多还原

【Abstract】 The paper introduces the principles,structure and characteristics of fault location device based on MCU+CPLD detailedly. In order to improve the measure precision and avoid the deadtime of the cycle memory, the CPLD is used to design the high-speed data acquisition and time-flag module.The simulation show the design is right.更多还原
