基于USB接口的惯导组件脉冲数据采集系统

摘要

This study addresses the limitation of test range and low precision in the testing of inertial components pulse data collection system. We adopted USB interface technology, collected inertial component pulse output data and stored and displayed the data in host computer. The design of USB interface was conducted by using the control chip CY7C68013 - 128AC of CYPRESS. Hardware circuit, USB firmware program, the application program of host computer were designed. The result of the test shows that this system can meet the requirements of testing.%针对目前所设计的惯导组件脉冲数据采集系统在测试的过程中所遇到测试范围小、精度低等问题，本系统采用USB接口技术，使用FPGA芯片对惯导组件的脉冲输出数据进行采集，并在上位机中对数据进行储存和显示．本系统选取CYPRESS公司的CY7C68013—128AC控制芯片进行USB接口电路的设计，完成了对硬件电路、USB固件程序、上位机应用程序的设计．经过试验表明，本系统能够完全满足测试的要求．
