| In recent years, with the development and general promotion of computer technology and network technology, urban construction archives of the whole country follow the national trend of the times, increasing their information technology, and has achieved achievement and experience to some degree in the informationization. The concept of "Digital City" has put forward, which provides a powerful impetus for the informationization of the national urban construction archives. Digital city is based on computer technology, multimedia technology and mass storage technology and makes the broadband network as a link. It uses remote sensing, global positioning system, geographic information systems, telemetry, simulation - virtual technology to make a 3- dimensional description of the city, which is multi-resolution, multi-scale, multi space-time and multi-species. That also is using information technology to conduct digital and virtual realization of all content of the city's past, present and future on the network. The file stored in Urban Construction Archives is a true record of the history of urban development, which should make its due contribution to the digital city. This article is in the background of the digital city, with Qingdao Digital UrbanArchives project, proceeding in-depth analysis and discussion of the digital urban construction archives building. Focus of this paper is a new input function of license archives, path archives, planning archives and the Sichuan aided archives; adding upload and online browsing of digital archives; adding online charging function of various departments in the digital urban construction archives; modified the fast query and borrowing process optimization function of file attribute information under the B / S architecture; The input function of spatial information of urban construction archives were researched and designed combined with GIS technology.The design and implementation of digital urban construction archives system of Qingdao is entirely based on the business processes and staff's working habits in urban construction archives of Qingdao, and is compatible with the original data. There are several key technologies in the implementation process of the system:1. Digital archives upload activex control. The control can support uploads and other features of drawings such as jpg, tif, bmp format, and video file such as and avi, rm format.2. Digital archives browsed activex control. The scan control can support online browsing of drawings which are common formats such as jpg, tif, bmp format; with the function of printing the drawings, and can achieve batch printing of multiple drawings and more than one printer.3. Data fast retrieval module under B / S architecture. The module can load a large volume of data unsynchronized and achieve top-bottom view of retrieving data by dragging the scroll bar without turning pages.Qingdao Digital Urban Construction Archives system uses a way of workflow, enabling the unified management of the file attribute data, digital archives and video archives in Qingdao Urban Construction Archives. A series of controls and related procedures (1,2,3 key technologies) which are developed based on staffing requirements can facilitate the business work of staff in archives, streamline operational processes, save time and improve efficiency. When the article is finished, Qingdao Urban Construction Archives system has been online, which has improved the archives management level and received good society efficiency and economic efficiency. |
