摘　　要：为满足某惯导设备生产厂家对多个惯组产品进行同时测试的需求,设计了一种对于多路脉冲信号同步计数的测试系统。(方法)测试系统以FPGA芯片和USB芯片CY68013为核心,对4个惯导组件输出的48路脉冲信号,每路进行无缝计数,每4ms为一个计数单元。并利用USB总线将每一个计数单元的计数值上传到测控计算机,上位机程序进行实时的处理、保存和显示。(方法)测试系统满足了对多个惯组产品同时测试的要求,提高了测试效率。In order to satisfy some inertial navigation equipment manufacturers to test multiplex inertial navigation products at the same time, introducing a design for multiplex pulse signal synchronous counting test system. The system is based on the FPGA chip Cyclone II EP2C8Q208C8N and USB FX2 chip CY68013 as the core, the 4 inertial navigation components output 48 pulse signal, each seamless counting, and each 4ms is a collection. Using USB bus transters data to Industrial computer, real-time processing, storage and display, Finally, output txt file. in order to meet the multiple inertial navigation products synchronous testing requirements.
