中文摘要:为了提高对扬尘实时监测的能力,基于BIM技术设计了公路征地拆迁中扬尘实时监测方法。利用传感器实时采集公路征地拆迁中的扬尘信息,并通过传感信息融合跟踪识别,对采集到的传感信息展开融合处理。然后结合参数自适应跟踪识别方法提取数据的谱特征量,再采用高阶谱分析方法实现谱信息聚类和特征融合,继而展开二乘拟合修正和信息修正。在此基础上,通过统计信息分析和BIM信息库融合的方法得到BIM信息调度函数,并设计公路征地拆迁中扬尘监测的BIM信息数据库,结合扬尘分布实现对公路征地拆迁中扬尘的实时监测。仿真结果表明,该方法对公路征地拆迁中扬尘的监测实时性较好,有效提高了对扬尘的实时监管能力。

Design of real-time dust monitoring method in highway land acquisition and demolition based on BIM technology
Abstract:In order to improve the ability of real-time monitoring of dust, a real-time monitoring method for road land expropriation and demolition is designed based on BIM technology. The dust information in road land expropriation and demolition is collected by sensors in real time, and the sensor information is fused, tracked and identified to carry out fusion processing. Then the spectral feature of the data is extracted with the parameter adaptive tracking and recognition method, and then the spectral information clustering and feature fusion are realized by using the high-order spectral analysis method, and then the quadratic fitting and information modification are carried out. On this basis, the BIM information scheduling function is obtained through statistical information analysis and BIM information database fusion, and the BIM information database for dust monitoring in road land requisition and demolition is designed, and the real-time monitoring of dust in road land requisition and demolition is realized by combining the dust distribution. The simulation results show that this method has a better real-time monitoring capability of dust in road requisition and demolition, and effectively improves the real-time monitoring capability of dust.
