虚拟蓄电池测试系统

The Virtual Test System of Battery

论述了基于FPGA与USB接口技术的虚拟蓄电池测试系统设计方案及其实现方法,重点阐述了基于FPGA中央控制器的设计原理,USB端点读写模块的设计,多路数据采样模块的设计及USB接口底层驱动的实现。利用VC++工具,采用面向对象等技术实现灵活的,通用的虚拟仪器面板。文中最后对系统性能和调试结果进行了分析。

This paper describles the design and implementation method of the virtual battery test system based on FPGA and USB interface technology, And explained the design principle based on FPGA central controller especially, the design of Read and Write module of USB endpoint, the design of muti channel data sample module and the realization of USB interface driven. Utilizing VC + + tool,based on Object Oriented Disign, we realize flexibly and common the virtual instrument panel. Finally, the paper analyzes the system performance.
