基于相关性矩阵的火控计算机测试平台设计

Design of Automatic Test Platform for Fire Control Computer Based on Pertinence Matrix

为解决新型装甲车辆火控计算机在维修保障上存在的检测深度不足、效率低、可靠性不高等问题,设计了用于装甲车辆火控计算机部件级、板级性能检测和故障诊断的自动测试平台;平台以相关性矩阵模型为基础、故障特征最大信息熵为准则进行优化测试点,从而设计了性能测试模块,并为故障诊断模块中故障字典的建立提供了测试结果信息,完成了软件设计;该平台最终可将故障定位到元件,在使用过程中检测深入、操作简便、稳定可靠,为装甲车辆火控计算机的维修保障提供了有力的支持。

According to the problems of the maintain actualities of the armored vehicle＇s fire control computer such as simple test, low efficiency and low dependability, the automatic test platform with performance test and fault diagnosis for component and circuit is designed. The platform based on dependency matrix and optimal criterion of the maximum failure feature information entropy, chooses optimal test points design. Performance test module is created and provides test result information for fault dictionary in fault diagnosis module. Automatic test platform is able to locate the circuit component failure. This platform is stable, reliable and simple to using. The platform effectively enhances the maintenance efficiency and quality of armored vehicle; s fire control computer.
