基于UWB的铁路营业线施工要素定位与风险防控研究
Study on the Positioning and Risk Prevention of Construction Elements of Railway Operation Line Based on UWB
摘要
Abstract
In order to solve the problem that the management of construction elements of railway operation lines is dependent on manpower and the risk management is lagging behind,a method of positioning construction machinery and personnel and risk prevention and control is developed based on UWB technology,and a visual management and control platform is established in combination with geographic information system(GIS).Taking a bridge project of an upper-spanning railway operation line as the research object,according to the hierarchical control requirements of operation line construction in the construction area,the UWB base stations and electronic fence boundary are optimally arranged,the positioning labels are configured for the construction elements,and then the positioning of construction elements is realized according to the TDOA positioning principle.The distance between the personnel and the construction machinery and the electronic fence is calculated by the positioning coordinates,and the safety risk graded early warning is compared with the preset threshold,and the graded early warning method of construction machinery collision avoidance and electronic fence is designed.On the basis of the above,the location information of personnel and machinery,as well as the safety risk graded early warning information,are integrated into the geographic information system(GIS),and the specific location of personnel and machinery can be viewed in real time and the safety early warning information can be automatically pushed on the GIS platform.In practical engineering application,the method of location of construction elements and risk early warning has a good effect,which can effectively enhance the safety of construction site.The results show that the designed method can realize the real-time positioning and display of personnel and machinery and the automatic push of safety warning effectively improve the intelligent safety supervision efficiency of railway operation line construction,and make up for the current shortcomings in the safety of personnel patrol at the construction site.关键词
