1 Introduction
With the continuous development of national urbanization and the expansion of urban construction scale, the management of urban planning and construction is becoming more and more complicated, and the traditional OA system can no longer meet the needs of modern urban planning, construction and management. This paper discusses the application of GIS technology and OA system technology in urban planning, construction and management to solve this problem, and takes the actual demand of Yibin Housing and Urban-Rural Development Bureau as an example. In the traditional urban planning and construction management, the results data are mainly saved in paper form, and when it is necessary to query and use, it can only be done manually, which brings inconvenience to management. GIS technology is introduced into urban construction information management system, which provides more scientific, comprehensive and efficient methods for urban planning, construction, management and decision-making, improves the level of decision-making and management, and promotes the informationization and modernization of urban planning, construction and management.
The data collection function of GIS can efficiently obtain urban planning and construction information; The information query function of GIS can quickly provide various spatial information, attribute information, statistical information and so on. The database management function of GIS can create urban planning and construction database, and run, manage and maintain it; The statistical and cartographic functions of GIS can display a large number of urban planning and construction data in the form of intuitive thematic maps or statistical maps; The professional application model function of GIS can predict, analyze, evaluate, simulate, plan and make decisions on urban planning and construction; The display and output function of GIS can display the urban planning and construction information of various media in real time, dynamically and interactively by using multimedia. This paper discusses the construction and application of urban construction information management system. Combining the business plan of "one book with two certificates", the system organically combines three systems: management information system (MIS), office automation system (OA) and geographic information system (GIS), and realizes the integrated management of drawings, documents and tables. According to the workflow and authority setting, the system realizes the acceptance, approval and certification of construction application projects through computer information management, and has the functions of acceptance, entry, filing, handling and approval of construction application projects, editing and printing of project notices, project permits, project red lines and other achievements.
2 Yibin City Construction Management Status
Yibin City has invested heavily in the collection and processing of spatial basic geographic information data, planning and construction management, and land management informationization. However, due to the lack of data sharing and data standard mechanism between departments and effective updating mechanism, the management of spatial basic data is scattered and lacks cohesion, and the use and mining of data are lagging behind, so the function of serving the government is limited.
3 Yibin city construction information management system design ideas
Integrate the existing surveying and mapping data to establish the urban spatial basic data platform, and construct the spatial basic data sharing and exchange mechanism; On the basis of urban spatial basic data platform, the construction of urban construction information management system is carried out, which lays the foundation for the update and improvement of urban planning and construction management system. 3. 1 system construction goal. Integrate the existing urban spatial basic data, establish an urban construction information management system, and improve the government's management ability in urban planning, construction, land management, underground pipelines, transportation and other aspects.
3.2 Work content of system construction. The GIS function in Yibin urban construction information management system is mainly divided into three application subsystems: service GIS application subsystem: this subsystem includes red line, setting out, line inspection and as-built drawing related functions that business departments need to use in the process of administrative examination and approval. Daily query GIS subsystem of basic spatial information platform based on Web: This subsystem is mainly used by bureau leaders and business departments to browse and briefly query some maps in their daily work. Integrated pipe network analysis subsystem: This subsystem includes two-dimensional application function and three-dimensional display function of integrated pipe network. The subsystem is integrated in the administrative examination and approval system, and the system is used from a unified entrance.
3.3 System structure design. Yibin city construction information management system and basic spatial information platform are deployed in the LAN of Housing and Construction Bureau. The basic spatial information platform is an important supporting data platform for the operation of Yibin city construction information management system. The website is deployed on the Internet. The system has an automatic exchange interface and can exchange data with the general software system of Sichuan administrative examination and approval business. Exchange data with the extranet website of Yibin Housing and Construction Bureau and the platform of Sichuan project information publicity and credit system by manual import and export.
3.4 Database Construction Project Planning Management Database: records data related to the project, such as project name information. Approval database: records the data of business approval process, such as approval opinions of each step. Basic spatial information platform database: records GIS related data. Project information disclosure database: among the publicly available project information, users can access it through the Internet. Development platform model base: records the data table definition, form interface definition, process definition and other information during system development.
Four main functional modules of the system
(1) project approval function module. Its function covers the whole examination and approval process of construction projects from site selection to completion, the management of enterprise qualification or industry examination and approval, and related inquiries and statistics. According to the actual business needs, it is divided into processed, business processing and business processing auxiliary functions. Business processing functions include creating new business, generating form default data, filling processing form, saving, submitting, retrieving, returning, accepting, rejecting, flow chart, etc. Auxiliary functions of business processing include automatically generating required legal application materials, adding materials, uploading electronic documents, scanning qualification materials, editing materials, deleting materials, generating processing results, certificates and printing business reports. (2) The function of commercial geographic information system. Including thematic map editing, map typesetting and printing, red line drawing, red line change, line setting, line inspection, spatial query statistics and spatial data conversion (CAD to GIS, GIS to CAD).
(3) Data exchange function. It is divided into manual data exchange interface and automatic data exchange interface. (4) Integrated pipe network GIS subsystem. Yibin Urban Construction Information Management System-Integrated Pipe Network System covers the spatial data of characteristic points and route directions of various pipelines such as electric power, telecommunications, tap water, drainage, rainwater, natural gas, etc., including pipeline uses, types, materials, starting point buried depth, end point buried depth, pipeline elevation, pipeline radius and other attributes. Including pipeline editing, pipeline query, pipeline statistics and pipeline analysis. Conclusion: The application of GIS in urban planning and construction management business solves the problem of single form of traditional OA system, realizes the integration of graphics and text, and meets the needs of practical work. The application of GIS technology in urban construction information management system is the key to the automation of urban construction management.
