Design And Implementation Of Bridge Management Information System For One City

With the construction of urban traffic network,more and more bridges have been built in the city,which has become an important part of urban traffic network.Due to the rapid development of all different industries,a rapid increase in transportation have taken place.The overloaded vehicles especially large-scale trucks,has caused serious damages to bridges,resulting in a serious shortening of life span of bridges,and risks to vehicles and people.In order to improve the efficiency of bridges and quality of projects,to reduce costs of manpower and material,and to decrease risks of bridge engineering,it is necessary to develop an information and digital management of bridges.This dissertation proposes a scientific and reasonable solution plan according to the actual needs for an information management of bridges.Through this plan,it will help bridge managers,inspectors and maintenance personnel to carry out information management,so as to achieve a standard,regulated and scientific management of bridges.This dissertation describes the analysis,design and implementation of the information system in details based on specifications of software engineering.The main work of this dissertation is as follows:First of all,through relevant information investigation,we get to know business needs of a construction company for managements of bridges,and understand its work contents,operating procedures and bridge management specifications.Then the theory and tools in terms of the software system requirement analysis are used to collate,classify and analyze needs of companies,so as to complete analysis of requirements of the system;Secondly,the overall system design work is completed on the basis of requirements of the system.This focuses on the logic design,system software,network architecture design and database design of core functions.Tools including class diagrams and timing diagrams are mainly used for analysis and design of business process of core functions of the system,to build a data model and business model of the system.Then,based on the previous research work,the system is implemented based on the principles of easy integration,easy expansion,and easy maintenance.The system's core module is mainly implemented based on results of the system design.Main focus has been given to realization of interface and code for core modules including bridge information,test data,analysis and evaluation,maintenance and repair,enquiry and statistics and management of document sending and reception.At last,according to the actual needs of each system module and its functions,the function of each module is verified through use of a common black-box test method.Through development and application of the system,it will promote a comprehensive information management of bridges by bridge managers,bridge inspectors,and bridge maintenance personnel,so as to realize a standard,regulated and scientific management of bridges.
