大容量机车信号记录仪的USB 2.0接口的实现
Implementation of USB2.0 in mass storage locemotive signal recorder
【摘要】 提供一个基于USB2.0接口的大容量机车信号记录仪的高速数据下载实现方案。系统采用USB接口引擎与单片机搭配的方式实现USB接口。在对USB协议和设备架构充分理解的基础上,设计了相应的硬件电路、固件代码和上位机工作在Win2000下的设备驱动程序。对比分析,本记录仪采用USB2.0接口实现数据下载,其传输速度比通用串口快近12倍,较好地满足了大容量机车信号记录仪的高速数据下载需求。
【Abstract】 Firstly some basic concepts of USB protocol and USB application background were presented, then given a method on how to implement high speed data download from recorder to PC by mean of USB2.0, which was included designs of hardware, firmware and windows driver.Finally it was explained how the data transmission requirement from client software implemented.
