Study On Safety Risk Management Of Metro Operation Based On BIM And IoT Technology

The continuous development of urbanization has led to a large number of population aggregation.In order to alleviate the traffic congestion caused by population aggregation,subway has become a very important link in the construction of urban transportation in modern cities.However,due to the particularity of the subway,the subway operation accidents happen from time to time.This paper,from the perspective of safety risk management of subway operation,supplemented by BIM technology and Io T technology,systematically proposes,discovers and solves problems.In general,this paper mainly does the following four things.(1)Through a large number of literature reading,the author summarized the preliminary precursor information of subway operation safety risk from the literature.In order to ensure that the subway operation safety risk precursor information is fully obtained.The author further obtains the precursor information of the safety risk of subway operation through case analysis and grounded theory.From the perspective of saturation theory,the final result is systematic and complete.(2)the author analyses the characteristics of the subway construction projects,with the characteristics of metro construction project information theory is put forward with coding and BIM platform to solve the subway equipment and facilities construction project information in fault and the loss of information transfer process,finally the author built a subway operation physical precursor information acquisition process and the system security risk physical system architecture.(3)The author analyzes the standard system of China’s Internet of Things,modern sensor technology,Internet of Things communication technology,and makes a specific explanation and understanding of them.Finally,based on Python programming language,smoke sensor and temperature and humidity sensor are used as simulation to build the monitoring system of the Internet of Things.(4)The author uses the BIM platform software Revit to simulate the construction of subway station A,and uses C# programming language and BIM platform software Revit2019 to realize the development of A visual early warning system for subway operation security risks.This paper includes 65 figures,16 tables and 146 references.
