Abstract

The monitoring data (current and rotational speed) of the subway sliding plug door transmission system changed positively and negatively with the acceleration and weight of the door. How to perceive the changes is a challenging problem in the health state assessment of transmission system. To address this problem, an enhanced perception health state assessment method was proposed for the transmission systems. In the method, firstly, the equivalent resistance force is calculated by monitoring the current and rotational speed data according to mechanical dynamic knowledge. Secondly, the sensitive features of normal and abnormal states are screened out from the enhanced dataset constructed by current, rotational speed data, and equivalent resistance force data. Finally, the health state of the transmission system is assessed using an integrated learning algorithm. The effectiveness of the method is verified by benchmark experimental data, and the results indicate that the method has a higher accuracy with four classifiers and a broader suitable range with varying door acceleration and weight.

地铁滑塞门传输系统的增强感知健康状态评估方法

地铁塞拉门传动系统的监测数据（电流和转速）随门的加速度和重量发生正负变化。如何感知这些变化是传动系统健康状态评估中的一个难题。针对这一问题，提出了一种针对传动系统的增强感知健康状态评估方法。在该方法中，首先，根据机械动力学知识，通过监测电流和转速数据来计算等效阻力。其次，从电流、转速数据和等效阻力数据构建的增强数据集中筛选出正常和异常状态的敏感特征。最后，利用综合学习算法评估传动系统的健康状态。基准实验数据验证了该方法的有效性，结果表明，该方法在使用四个分类器时具有更高的准确性，并且在车门加速度和重量变化时具有更广泛的适用范围。

期刊介绍： Measurement Science and Technology publishes articles on new measurement techniques and associated instrumentation. Papers that describe experiments must represent an advance in measurement science or measurement technique rather than the application of established experimental technique. Bearing in mind the multidisciplinary nature of the journal, authors must provide an introduction to their work that makes clear the novelty, significance, broader relevance of their work in a measurement context and relevance to the readership of Measurement Science and Technology. All submitted articles should contain consideration of the uncertainty, precision and/or accuracy of the measurements presented. Subject coverage includes the theory, practice and application of measurement in physics, chemistry, engineering and the environmental and life sciences from inception to commercial exploitation. Publications in the journal should emphasize the novelty of reported methods, characterize them and demonstrate their performance using examples or applications.
