摘要
为了满足远距离数据传输的需求,结合Wi-Fi等无线通信技术,开发了基于虚拟USB-HID的无线数据传输系统。简要介绍基于微软DSF架构进行虚拟USB驱动开发的原理,并应用对称加密技术和非对称加密技术,通过虚拟USB-HID驱动程序实现USB数据的远程无线传输。该系统成本低、传输速率高、性能稳定,已在无线仿真器设备上应用,实现了嵌入式软件的远程仿真调试。
In order to meet the demand of long distance data transmission,a virtual USB-HID-based wireless data transmission system is developed in combination with wireless communication technology>such as Wi-Fi.The principle of virtual USB drive development of Microsoft DSF architecture is briefly introduced.By using symmetric encryption technology and asymmetric encryption technology)long distance wireless transmission of USB data can be realized via virtual USB HID driver.The system featured with low cost,high transmission rate and stable performance and has been applied in wireless simulator which realizes remote simulation debugging of embedded software.
