Study On The Construction Of Subway Station Monitoring And Early Warning Management System

Since twenty-first Century, the city traffic congestion is becoming more and more serious, a good way to solve city traffic problems is the construction of the subway. The construction methods of subway station include cover excavation method, the open cut method, subsurface excavation method and so on. Construction sequence include reverse and normal. Construction safety influenced by various factors, includes geological, hydrological, ground load, construction method and so on. It’s often difficult to predict. Because the monitoring program and monitoring have large amount of data, so how to effective management has become the key factor in the safety monitoring of subway construction. In recent years due to the effective management of monitoring data, monitoring project can’t lead to timely warning, eventually led to the construction of the tragedy happens. Therefore, the development of a set of complete, effective, timely and accurate monitoring and early warning information management system of information monitoring of subway construction is becoming more and more important.Subway construction monitoring to quasi real time grasp the construction safety through the monitoring project, subway construction monitoring in the traditional monitoring report on the results of daily paper form, the lag time, rigid in form. Based on this, this paper is based on the necessary monitoring of construction projects, design and development of the Logistic-Richards weighted combination forecasting model of subway station construction monitoring and early warning system based on information management, the system can real-time processing, analysis and prediction of the monitoring results, classification and time series stores all the monitoring data from the project to the end of the project, store the data at any time to call the analysis and data processing, and the graphics interface and the form of expression, the system can serve for scientific management and decision-making of the safety of subway station.The main research contents are as follows:First, Describes the present situation of the construction monitoring of subway station at home and abroad, introduces the main content of the construction of the subway station, monitoring procedures and processes.Second, According to the forecast model of metro construction monitoring data processing, using the principle of combination forecasting model based on forecasting model, analysis of a variety of monitoring data, summed up the weighted Logistic-Richards model and weighted Logistic-Richards model, combination forecasting model for the effective application.Third, The limitations of traditional subway construction monitoring and reporting forms based on the achievements management, design and development of a preliminary construction of subway station monitoring and early warning management information system. Design of the monitoring system needs analysis and system solutions, realize the system function, the system can be a full range of three-dimensional virtual roaming subway station, and according to the time sequence of classification in the form of database management of the monitoring data, monitoring results of time series can be generated by the data and graph forms of expression, based on the national standard design of threshold as the basis, can carry out automatic warning and sending mobile phone short message form to management decision-making, the subway construction monitoring information.Last, To the people of Shenzhen South Railway Station as an example, the realization of the monitoring data from the people of the South Railway station construction management, analysis and prediction of early warning, and the management information system of summary and outlook...
