Cai Jianchen Shao Zhishan Changzhou City Lighting Management Office (213022) Abstract Taking Changzhou as an example, the preliminary results and application value of urban lighting geographic information system development are expounded. Key words lighting geographic information system development and application 5, the development of the target system will enable Changzhou city lighting management personnel to more effectively manage the street lights, while also greatly improving the efficiency of street lamp management, making street lamp maintenance management work more timely, More accurate, which saves a lot of manpower, material and financial resources. The complete Changzhou Urban Lighting Geographic Information Management System has the following functions: (1) The terrain map management topographic map has a large amount of data. In order to improve the efficiency of display and query, the framing storage method is adopted, and the system provides the library management function to realize The splicing of the framing and the way of querying across the frames make the physical framing of the graphics logically integrated. In addition to providing the functions of inputting and editing the spatial data and graphic attributes of the three elements of points, lines and zones, the most important thing is to realize the topographic map construction, flexible management of the library and convenient data conversion. (2) The data input editing system provides rich and powerful means of inputting Street Lighting facilities, constructs network topology relationships, establishes an attribute database related to street lighting facilities, and provides graphic attribute editing tools. For graphic data input, the system has various means, such as digitizer input, scan vectorization, direct transfer of field detection data results table, conversion of Other data formats, manual entry of mouse and keyboard, and the like. (3) The urban lighting facility management system can quickly and comprehensively analyze and analyze the current streetlight information through some effective methods, and can quickly generate statistical result maps, which can guide the management personnel to manage and make decisions efficiently and correctly. In addition, various information tools and information are conveniently obtained through various inquiry tools, measurement tools, positioning tools, and the like. At the same time, the street lamp line maintenance management subsystem is also responsible for attaching the external database to maintain the topology integrity and data consistency of the street lamp line. Crop output: Provides rectangular cropping, polygon cropping, circular cropping, arbitrary polygon cropping, automatic addition of icons, output according to a certain ratio; Measurement: measuring the distance between two or more points, the length of the polyline, and the rectangle, circle, Peripheral and area of ​​arbitrary polygons; Positioning tool: hierarchical positioning of the entire data range, providing search and positioning means for various ways such as division and place name; Statistical tools: various attributes for a certain area and certain types of street lighting equipment Statistical charts, and the results are printed in the form of an intuitive table or statistical chart (such as a pie chart); Query tool: query according to the line; demarcate the regional location query; specify the device type for query; construct the search condition query; Custom condition query; Auxiliary data: Provide convenient and flexible static labeling and dynamic labeling method to mark street lamp lines and equipment; Equipment library management: Provide centralized management equipment, including the professional name of the equipment, the type of equipment, and the graphical symbols of the equipment. Allow users to add, delete, edit, etc. Provides intuitive reference material for managing repairs. (4) The operation management that is more closely integrated with the operation and daily office is mainly to deal with the daily work during the operation of the street lamp, including repair, maintenance of the account, maintenance records, rams, etc. to achieve paperless office, which can be done at the end of the month or at the end of the year. The problems that occurred during this period were counted, and they could also provide valuable reference for future procurement of materials and provide historical data for future management. (5) The auxiliary analysis system has the function of assisting decision-making. On the existing street lamp running line, the simulation fault range, finding the power point, brightness, illumination, and glare calculation are provided, which provides a scientific basis for decision makers to accurately formulate the plan. (6) WEB release By establishing a WEB publishing system, users can directly access the home page of the geographic information system through a web browser, browse graphics, query device information by type, region, and condition, implement specific device search, and view street lamp facilities and information. And do online work. This makes it easy to browse and manage the system without installing any additional software on the browser. The WEB publishing system interface is shown in Figure 9. ![]()
