【摘要】 本文针对弹载记录器的性能测试,设计了配套的地面测试台。通过对系统功能指标进行分析,提出了测试台设计方案:采用FPGA作为中心逻辑控制器,USB进行数据传输,系统采用总线方式和模块化设计方法,具有很强的通用性和可扩展性。按照各模块的功能,分别从硬件电路和逻辑时序设计两方面进行了介绍。针对电路板中可能出现的电磁兼容性问题进行了仿真分析,并给出了PCB的电磁兼容设计方法。论文对系统设计和调试过程中遇到的重点和难点问题,进行了充分的分析,提出了解决方法。在硬件电路设计和逻辑时序设计中,采取了有效措施来防止系统出现误操作,提高了系统的可靠性。对于系统单元测试时实时监测出现误码的问题,借助串扰仿真和分析误码数据,判断出误码原因并进行相应修改。经过最终测试,证明所采取的措施是有效的。测试台与记录器进行了单元测试,整个系统工作正常,测试台各项功能指标均满足系统要求。更多还原

【Abstract】 For the performance of missile-borne recorder, test equipment is designed specially to measure it. Through the analysis of system function, the thesis presents the design program of test equipment: FPGA as the central controller,USB for data transmission. The system has strong universality and extensity by using the design method of bus and module. The thesis introduces circuit and logic-timing design according to the function of module. This thesis makes the simulation and analysis against possible problems of electromagnetic compatibility in the circuit board, finally provides the design method of electromagnetic compatibility.The thesis makes sufficient analysis against the key and difficult problems in the process of system design and debugging and gives out the solution. In the design of hardware circuit and logic-timing, the project takes effective measures to prevent misuse of system and so improves the reliability of the system. About the problem of error-code in real-time monitoring of system unit testing, we use crosstalk simulation and analysis of error-code data, finally determines the reasons of error-code and revises it in time. After final testing, it demonstrates that the measures taken are effective.The test equipment and recorder have taken the unit testing. The entire system works well and all functions of test equipment meet the system requirements.更多还原
