测量船惯导系统单板故障检测平台的设计

为了提高维护效率,实现对单板故障的快速诊断,设计开发了惯导系统单板故障检测平台.该检测平台硬件上以FPGA为逻辑单元,采用ISA总线与上位机进行通信,软件方面采用Visual C++开发驱动程序和调用函数程序,供上层程序调用,采用虚拟仪器LabVIEW开发用户界面、测试程序和控制程序.最后,以SM_MB板卡为例实现对单板故障检测平台的测试验证,结果表明,该平台操作简便、测试可信,满足测量船惯导系统电子单板快速故障诊断的要求.

Design of single board fault detection platform for the integrated navigation system on the tracking ship

In order to improve the maintenance efficiency and realize the rapid diagnosis of the single board fault,the fault detection platform of the inertial navigation system is designed and developed.The detection platform hardware based on FPGA logic cell and communicated with PC by ISA bus,the software develop driver program and call functions program called by the upper procedure using Visual C + +,the user interface,test procedures and control process using Virtual Instrument LabVIEW.Finally,with SM_MB card as an example implementation of single board fault detection platform test.The results show that,the platform is easy to operate and trustworthy,to meet the requirements of the fault rapid diagnosis test of the inertial navigation system electronic single board of the tracking ship.
