The Design And Implementation Of Network Management Systemof Metro Construction Monitoring Information

Developing the management system of metro construction monitoring information can coordinate with all participants in the subway construction to do business with others,which can share the survey results with other departments and ensure the safety of the urban rail transit project together.The related system functions mainly focus on data entry and management,calculation and query of the data,the analysis of the alarm information.However,the systems have problems of the difficulty in multi-user management,the inefficiency of the integration and management of multi-source data,the delay of detecting and sending the alarm information,the complex process of dealing the information cooperatively in the network environment.Carrying out the research about the design and implementation of network management system of metro construction monitoring information to solve the above problems with the help of the technologies such as geographic information system,net communication,mobile GIS,data base and component development,this paper breakthrough the key technologies of the optimization of multi-level user management and the automatic detection,the fast notification and the co-processing of alarm information.The main work in this paper is consisted of the following aspects.(1)The optimization of multi-level user management and the data integration management.Reorganizing the origin and species of all kinds of monitoring data and the relationship between participating departments and analyzing the business requirement from three aspects of system,function and data in detail,this paper proposed the optimization method of multi-level user management,carried out the research on system privilege,function permission,data integration management and authority allotment and realized the clear definition and the optimization management of the authority,which provided support for the integration and share of monitoring results,the detection and the co-processing of alarm information.(2)The automatic detection and the co-processing of alarm information.Analyzing the workflow and the technical method of the existing disposal of alarm information,reorganizing the user demand of all participating units in metro engineering and researching the general procedure of processing the monitoring data,this paper came up with the analytical method of the automatic detection of alarm information,designed the information content and the start mode of alarm notification and achieved the technology of releasing the alarm information timely based on short message.And then,this paper designed the process of alarm information co-processing and realized the automatic detection and the co-processing of alarm information,which solved the problems of the low automation of alarm detection,the delay of alarm release and the complex process of dealing alarm information(3)Prototype system developments and case experiment analysis.The monitoring project of Hangzhou metro line 4 were selected to carry out an experiment,and this paper developed the network management system of metro construction monitoring information and proved the realization and application of the multi-user privilege,data management and the alarm information co-processing.The experimental results showed that the research achievements in this paper could store and manage the all kinds of data in construction monitoring effectively,release timely and assist processing on alarm information.
