Description

Electronic map identifier drawing system and method for urban street lamps
Technical Field
The invention relates to an electronic map identifier drawing system and method for urban street lamps.
Background
With the development of science and technology, the application of the GIS system in the operation monitoring and control of the street lamp facility is more and more frequent, and the GIS system can perform the functional operations of geographic display, information monitoring, management and control of the street lamp facility, timely telemetering of running data of the street lamp facility, analysis and processing of running real-time information, timely storage of measured data, real-time running data GIS display, historical data GIS display and the like. By combining the street lamp facility operation monitoring and management system with the GIS, the display modes of the street lamp facilities by the public service street lamp management department and the street lamp industry operation and maintenance department are improved, the street lamp facility maintenance efficiency is improved, and the management cost is reduced. However, the existing street lamp facility operation monitoring and management system still has the following problems in the aspect of showing city street lamps in the GIS:
1. the general GIS is not used for the identification of urban street lamps or can not meet the actual requirement.
The general GIS mainly refers to an integrated GIS and a modular GIS, and the limitation of general GIS software is increasingly prominent along with the expansion of the application field of the GIS. The limitation of the general GIS in the aspect of intelligent lighting of the urban street lamps is mainly reflected in the lack of models and symbolic identifications applied to intelligent lighting of the urban street lamps, and the existing symbolic identifications can not meet the actual requirements. Therefore, the general GIS has a great defect in the aspect of displaying the urban street lamp illumination.
2. The manual drawing of the symbolic identification of the urban street lamp is slow, the workload is large, and the identification standardization degree is not high.
When the urban street lamp application management utilizes the GIS to display, the basic state, the running state and the alarm state of street lamp facilities need to be displayed, so that the total number of the state symbolic identifications displayed in the GIS by the urban street lamps is numerous, for example: when 4 lampholders are arranged on a lamp post of an urban street lamp, if 4 states such as lamp turning-off, lamp turning-on, uncontrolled state and failure need to be displayed, the number of required icons is the multiplication of the total number (4) of the lampholders and the display state (4), and 4 x 256. For a middle-pole lamp, a high-pole lamp and other types of lamp poles with more lamp holders, the number of icons needing to be identified is more, and if all the state icons are drawn manually, the problems of large workload, much time consumption and inaccuracy in icon making exist, and when the state icons need to be updated, the updating is tedious and slow.
3. The street lamp facility resource information display cannot be detailed and proper and the loading is slow.
When the GIS is adopted for displaying street lamp facility information, the display of street lamp equipment with a large number and variety by the traditional GIS is not good in the aspect of appropriate details due to the influence of the density of lamp posts and the scale of a map.
When the map scale is large, street lamp equipment information in the map visual range is as simple as that displayed when the map scale is small, and at the moment, more detailed street lamp facility information is required to be displayed; when the map scale is small, the map visual range is large, the number of street lamp facilities in the visual range is large, the data loading is slow due to the fact that the street lamp facilities are completely read and loaded from the database, and the user experience is reduced; after the loading display, the display density in the map visual range is too high, so that the icons are mutually covered or shielded, street lamp facilities cannot be distinguished, and the viewing effect is influenced.
4. The display of the street lamp facility resource information is not intuitive and is slow.
At present, the total quantity of street lamp equipment in a slightly-scaled city is more than hundreds of thousands, and the street lamp facility resource types are various. With the enlargement of the urban scale, the number of street lamp facilities increases in a geometric progression, and in the face of such huge facility data and complicated equipment types, when the existing street lamp facility management system is used for displaying the street lamp facilities, application lists, diagrams and the like are displayed, so that the problems of non-visual display effect, slow data loading and displaying speed and the like exist.
