从技战术实际需要出发,给出了某型飞机作战损毁后机载电缆的智能化诊断系统的硬件结构框图。根据硬件系统模拟开关组件的原理,定义了电缆的连接矩阵、测量矩阵以及断口的映像矩阵运算,给出了断头查找的算法。计算表明,系统可在20 min内完成一个循环的断头查找并给出故障定位。 Based on the actual needs of technology and tactics, the hardware structure diagram of the intelligent diagnosis system of airborne cable after a certain type of aircraft is destroyed is given. According to the principle of hardware switch module, the connection matrices, measurement matrices and image matrices of the fracture are defined, and the algorithm of broken ends search is given. The calculation shows that the system can finish a loop break-break search within 20 min and give the fault location.
