The invention discloses an elevator running quality monitoring system and method, and the method comprises the steps: 1, obtaining the acceleration, current, vibration and position multi-mode signals of an elevator, and carrying out the time synchronization and physical correlation analysis, so as to convert a plurality of signals into a joint feature space; 2, taking the joint feature space as input, and improving the resolution of the multi-modal signal by using quantum calculation to obtain an enhanced signal; step 3, reconstructing a multi-mode signal of the elevator based on the enhanced signal, and generating a virtual mode to reflect a running track of the elevator in a constant speed state; and 4, on the basis of the generated virtual mode, the running state of the elevator is monitored in real time. According to the method, the precision problem of feature extraction in the constant-speed state is solved, tiny signal changes in the constant-speed state can be effectively captured, the monitoring precision of the elevator running state, the fault detection capacity and the early warning timeliness are improved, and the performance of an elevator monitoring system is remarkably enhanced.

    本发明公开了一种电梯运行质量的监测系统及其监测方法,包括:步骤1:获取电梯加速度、电流、振动和位置多模态信号,并进行时间同步和物理关联性分析,以将多个信号转换到联合特征空间;步骤2:以联合特征空间作为输入,利用量子计算提升多模态信号的分辨率获得增强后的信号;步骤3:基于增强后的信号重建电梯的多模态信号,并生成一个虚拟模式,以反映匀速状态下电梯的运行轨迹;步骤4:在生成的虚拟模式的基础上,实时监控电梯的运行状态。本发明克服了匀速状态下特征提取的精度问题,能够有效捕捉到匀速状态下微小的信号变化,提升了电梯运行状态的监测精度、故障检测能力及预警的及时性,显著增强了电梯监控系统的性能。
