某型导弹电子舱地面数据采集分析系统实现

Data Acquisition and Analysis of Electronic module of Missile

针对脱离弹体后的电子舱无法进行实时数据采集分析的这一问题,提出使用VI和FPGA配合的独立模拟测试平台方案,利用FPGA模拟各类故障检测信号并且使用直接注入至电子舱的方法,用以解决在保证使电子舱加电正常运转的前提下使用VI技术实现独立采集和检测电子舱各类参数和性能指标目的;经实际检测结果验证,该数据采集分析系统能够独立地完成电子舱各类故障模拟并且能实时采集、记录、分析和显示电子舱的若干相应信号,为电子舱的性能分析、评价和故障定位分析等提供了重要的数据参考。

Aimed at the real time data acquisition and analysis of electronic module, a independent platform of test using VI and FPGA is put forward. This method simulates all kinds of fault detection signals and feed the signal into the electronic module to test the performance of electronic module. It is demonstrated that the system can simulate sorts of fault detection signal, acquire, record, analyze and display corresponding signals of electronic module. The system will be an excellent reference o~ characteristic analysis, evaluation and fault location.
