The invention provides a passenger and goods elevator roof bearing capacity evaluation method with a self-adaptive early warning function, which comprises the following steps of: acquiring data of a multi-source sensor, and performing data acquisition and preprocessing by adopting a dynamic synchronous sampling optimization algorithm; extracting time-frequency characteristics, separating load modes by adopting a multi-dimensional time-frequency analysis algorithm, and constructing a dynamic load spectrum; establishing multi-scale state mapping, calculating system response by adopting a generalized dynamic response analysis method, and evaluating structural risk; and constructing a self-adaptive early warning system, dynamically optimizing an early warning threshold value, and generating an optimal decision scheme. According to the method, the sampling strategy can be adaptively adjusted, the load characteristics can be accurately recognized, multi-scale state evaluation is achieved, early warning decisions are dynamically optimized, and the accuracy and reliability of people and goods elevator top plate bearing capacity evaluation are remarkably improved.

    本发明提供一种具有自适应预警功能的人货电梯顶板承载力评估方法,包括以下步骤:采集多源传感器数据,采用动态同步采样优化算法进行数据采集和预处理;提取时频特征,采用多维度时频解析算法分离载荷模态,构建动态载荷谱;建立多尺度状态映射,采用广义动力响应分析方法计算系统响应,评估结构风险;构建自适应预警系统,动态优化预警阈值,生成最优决策方案。该方法能够自适应调整采样策略,准确识别载荷特征,实现多尺度状态评估,动态优化预警决策,显著提高了人货电梯顶板承载力评估的准确性和可靠性。
