基于USB2.0的数据记录器地面综合测试台设计

The Data Memory Integrated Ground Test Bench Design Based on USB2. 0

提出了一种基于USB2.0的数据记录器地面综合测试台的设计方法,选用现场可编程门阵列(FPGA)作为逻辑控制器件,实现了对箭载数据记录器的闭环自检;同时配合记录器完成对火箭内部参数的测试。着重从系统硬件电路和逻辑时序两方面进行研究设计,讨论了系统各功能模块的实现方法;并对各模块进行了实际的分析和测试。经大量测试表明该装置性能稳定,可以满足设计要求。

A ground test bench based on USB2.0 is designed,Implements the performance indicators of memory closed-loop self-inspection,at the same time cooperate with the data memory to complete the rocket internal parameters test and storage.paper describes the unit test bench from the hardware circuits and logic timing,and gives the test results.Through a large number of tests show that the device has stable performance,the design requirements can be meet.
