摘要
介绍了一种针对于铁路信号设备特性检测的便携式大容量测试系统的设计。该测试系统以带有片上USB控制器和D/A转换器的高度集成处理器C8051F340为核心器件、采用SD卡存储技术和USB总线技术实现了便携式大容量存储的功能。可以方便地完成铁路信号设备的多种特性参数的现场测试和大容量存储。
A portable and massive storage measurement system was introduced which is suitable for per- formance measurement of railway signal device. Its core part is a highly integrated device of C8051 F340 that contains an on-chip USB controller and a D/A convertor. The function of portable and massive stor- age is achieved by SD card and USB bus and could be used to conduct site measurement and massive storage of various performance parameters conveniently over railway signal device.
