[0001] MULTI-DIMENSIONAL OBJECT-ORIENTED BRIDGE INFORMATION PROCESSING SYSTEM AND METHOD [0002] MULTI-DIMENSIONAL AND OBJECT-ORIENTED DATA MANAGEMENT SYSTEM FOR BRIDGE BASED ON MOBILE FIELD INSPECTION, AND METHOD FOR THE SAME [

The present invention relates to a bridge information processing system, and more particularly, it relates to a bridge information processing system in which a person in charge of managing a plurality of bridge structures inquires existing multi-dimensional information using an intuitive user interface without expert knowledge or expertise The present invention relates to a mobile field survey-based multidimensional object-oriented bridge information processing system and method thereof.

Generally, in order to input information into a bridge management system by accessing a bridge management system that stores useful information to a manager by storing, accumulating, utilizing, and analyzing the information of the bridge, (E. G., Smart phones). ≪ / RTI >

Numerous infrastructures have been constructed along with the economic development in Korea. However, systematization and advancement of information management of infrastructures such as public roads, bridges, tunnels, dams, and harbors are insufficient. Also, The input method of the field information is not implemented in an administrator or a user friendly environment by utilizing the latest information technology and it is difficult to secure the reliability of the collected data.

For example, existing facilities management systems are not able to provide useful information because information on management sites and information on management systems are not efficiently linked and circulated, but are merely based on information input. Also, since the information input method utilizes text or a two-dimensional plane, the inputting easiness is very low.

On the other hand, in the field of construction, the BIM (Building Information Modeling) method is applied to improve the quality of construction work by integrally managing the stereoscopic design of public facilities and the information generated during the entire life cycle.

However, most information management is focused on solving the problems in planning and designing. In the planning, design and construction phases, the users and users of BIM are limited to the engineers who have the technical expertise. There is a limit to the use of this by the person in charge of the maintenance of the facility have.

Meanwhile, a life-cycle management technique for managing an infrastructure network has been applied, and a more efficient method for linking information generated from a management site (maintenance activity) to a management system has been developed.

As shown in FIG. 1, the maintenance activity (10) includes all activities performed at the management site of actual bridges such as visual inspection, safety diagnosis, budget estimation and construction work, and various related information is generated. Information generated at the maintenance site is input to the information management system 21, and the information analysis system 22 performs various analyzes using the input information. That is, the management system 20 includes the information management system 21 and the information analysis system 22, wherein the information analysis system 22 is for supporting performance prediction, cost estimation and decision making, The results analyzed through the analysis system 22 are utilized as a basis for determining which maintenance activities 10 to perform. For example, it will determine the maintenance activity budget, and decide which bridges to carry out safety diagnosis or maintenance. Thus, the maintenance activities (10) and the management system (20) must be linked and the information circulated.

On the other hand, the reliability of the information input through the maintenance activities (10) such as the structural information of the bridges, the inspection and the diagnosis information, etc., determines the reliability of the information analysis. However, the reliability of the untrained non - experts of the management body responsible for bridge management is low. Therefore, it is necessary to develop a system that can provide basic information for judgment by providing various similar case information and history information to the bridge inspection person, and can easily input the judgment result.

In addition, the effort to make the database (DB) of the information generated in the structures in the infrastructure network has mainly been focused on the development of the DB system accommodating information. However, due to the development of the information communication technology, Research and development on the method of inputting the information used has recently been advanced.

At this time, the processing method of information generated is progressing from procedural, structured, and object-oriented steps in terms of a program, and processing tools include text or 2D drawings / photographs Based wireless communication devices are being applied.

A facility management method using a facility identifier according to the related art is a method of converting an object identifier formed in a CAD diagram into a facility identifier that can be identified in the entire facility and a facility management method using the converted facility identifier, A method for converting an object identifier identified only in each of a plurality of CAD drawings showing a facility into a facility identifier, and a method for managing facilities by linking the converted facility identifier and facility management information.

In the case of the facility management method using the facility identifier according to the conventional technology, it is not necessary for the user to directly input the facility identifier, and the user does not need to directly input the basic information shown in the drawings, The facilities can be managed collectively by forming a facility identifier automatically by combining identifiers

On the other hand, Korean Patent No. 10-688288 discloses an invention entitled " Facility maintenance management system and facility maintenance method ". The facility maintenance management system in the construction CALS operated by the Ministry of Land, Transport and Maritime Affairs Are managed on the Web and 2D basis.

On the other hand, it is necessary to improve the information management system of existing public infrastructures using the latest information and communication technology, and to maintain the credibility of the site information. It is possible to establish.

Particularly, it is possible to use various members such as bridges (for example, pavement pavement, bottom plate, mold, secondary member, shift / pier, foundation, railings / curb, drainage facility, expansion joint, (Eg, river, mountain, coast, flood, typhoon, earthquake, etc.) and traffic environment (for example, In order to manage structures with varying degrees of degradation, more careful management is required than other infrastructure structures.

To accomplish this, it is necessary to manage multi-dimensional information such as location, drawing, photograph, status and cost of existing infrastructure and differentiated infrastructure, object-oriented information processing based on major components of bridge structure, integrated management of all component information in bridge network Is required.
