摘要

运输基础设施物体暴露在大量载荷下，这些载荷会导致位移、弯曲、磨损、裂纹、断裂、腐蚀和其他缺陷的形成。结果表明，在物体发生故障的时刻，来自相应传感器的噪声信号的噪声取与有用信号相关的临界值。因此，开发了用于计算随机噪声接受临界值的概率、噪声的临界值与有用分量之间的相关系数以及中继互相关函数的算法。根据对开发的噪声特性的估计，提出了监测交通基础设施对象技术条件的技术。进行了计算实验，验证了所开发的算法和技术的可靠性。

TECHNOLOGIES FOR MONITORING THE TECHNICAL CONDITION OF TRANSPORT INFRASTRUCTURE OBJECTS BASED ON THE COEFFICIENT OF CORRELATION BETWEEN CRITICAL VALUES OF NOISE AND USEFUL SIGNALS

Transport infrastructure objects are exposed to a large number of loads, which cause the formation of displacements, bends, wear, cracks, breakdowns, corrosion, and other defects. It is shown that at the moment of initiation of malfunctions in objects, the noise of the noisy signals coming from the corresponding sensor takes critical values that correlate with useful signals. Therefore, algorithms are developed for calculating the probability of random noise accepting critical values, a coefficient of correlation between the critical values of the noise and the useful component, and a relay cross-correlation function. Technologies for monitoring the technical condition of transport infrastructure objects are proposed based on the estimates of the developed noise characteristics. Computational experiments are conducted, and the reliability of the developed algorithms and technologies is confirmed.
