中文摘要: 设备健康度是对设备健康状态的定量评估,可以更准确地反映设备健康状态.现有健康度评估方法并不能很好地反映设备的真实健康状态.针对某型雷达发射机的健康度评价问题,提出了基于动态权重的健康度精确评估方法.本文利用指数函数对各参数的权重动态变化规律进行建模,然后计算采集向量与最佳向量的加权标准欧式距离,可以更加准确地评价设备的健康度.通过对某型雷达发射机的实际测试表明,本方法计算结果准确可靠,能够更好地反映设备的健康程度.
Abstract:Equipment health is a quantitative assessment of the health status of a device and can more accurately reflect the real health status of the device. Existing health assessment methods do not reflect the health status of the device. Aiming at the health evaluation of a certain type of radar transmitter, an accurate health assessment method based on dynamic weight is proposed. In this study, the exponential function is used to model the dynamic variation of the weight of each parameter, and then the weighted standard Euclidean distance between the acquisition vector and the best vector is calculated, which can evaluate the health status of the equipment more accurately. The actual test of a certain type of radar transmitter shows that the calculation result of this method is accurate and reliable, and can better reflect the health status of the equipment.
