摘要
本文针对舰船消磁设备的测试需求,设计了基于虚拟仪器技术的集成测试系统。本文从硬件、软件两个方面介绍了该系统的设计方案与实现方法。该系统采用了USB通用串行总线,具有示波器、信号发生器和通用测量功能,利用故障树和专家系统实现了对设备各组件的功能测试和故障分析,并可根据反馈控制理论对消磁设备做出性能分析。在生产检修过程中的应用表明,该测试系统提高了测试精度和测试效率。
For the need of testing of ship degaussing apparatus, the integrated test system based on virtual instrument technology has been designed. By describing its hardware and software in order, the designing and realizing method of the system based on the VI technology is described. This system adopts USB bus. It can be used as oscillograph, waveform generator and Muhimeter. The functions of the degaussing apparatus modules were tested and the faults were found by using the theory of fault analysis branch and diagnosis expert system. The theory of feedback control system is used to analyze the performance of the ship degaussing apparatus too. Application in testing indicates that the precision and efficiency has been improved.
