Research on Street Light AM/FM/GIS Construction 奚 Hui Zhang Shuliang 2, Ruan Guonian 2 (Nanjing Street Light Management Office, Nanjing 210013; 2 Nanjing Normal University Geographic Information Science Jiangsu Province Key Points: 2.2.2 Street Light AM/FM/GIS System Function Description I. Equipment and facilities management: mainly for the management of distribution equipment, box-type transformers, wiring wells, control lines, overhead lines, cable lines, poles, high pole lights, etc. The management of equipment and facilities lines mainly includes graphics Management and accounting management. Graphic management is mainly to add, modify, edit, and delete equipment and facilities graphic elements on the geographic map, including setting direction for control lines, customizing colors for overhead cable lines, and giving users facilities and facilities. Custom map symbols, etc.
The account management is mainly for the attribute editing of the equipment facility line, and it can also save images for the equipment facility line, and can manage the lamp type of the street lamp.
In the map, the map is mainly composed of the basic geographic map and equipment facility wiring layers. The basic geographic layer mainly includes: administrative divisions, blocks, roads, buildings, etc.; the equipment and facilities route layer is a layer that is added by the user to the geographic map and operated by the user. Through the layer management module ±, the user can change the color of the basic geographic layer, display range, map annotation and other information. The graphic display is mainly for graphic enlargement, reduction, stepless roaming, and automatic adjustment control of density.
A navigation window is provided during the roaming and browsing of the prepared graphics, and the full image is associated with the window. In this way, when roaming, the navigation window can be used to know that the map of the current view is in the range of the entire map, and the map can be easily repositioned.
W. Bookmark management. Bookmark management includes area and location targeting of bookmarks. The regional positioning is mainly to define the polygons on the map, and customize the management and inspection scope for the user, so that the system can be used to clearly define the division of responsibilities and strengthen the work supervision. Position positioning is mainly to define a certain field of view on the map, so that the user can quickly locate a certain position on the map at any time when using the system, avoiding repeated enlargement, reduction, and roaming operations.
V. Device tree management. In the tree window of the system, the user selects a geographical area or a street light line, and the area or line management can be realized by right-clicking the menu. Including area, line device statistics, area, line location, and viewing of operational information.
Select the leaf node of the tree window, that is, the street light device, and the right-click menu provides the user with device management, including basic functions such as management of device graphics and management of device account information. The structure of the device tree is as follows: the connection between its systems. The existence of application integration functions makes it possible to share the AM/FM/GIS data and functions of street lamps, avoiding the “lone GIS application integration functions generally including: real-time data display, integration with SCADA systems; engineering management, implementation and engineering management systems Integration; equipment facility resource lifecycle management, integration with material management systems, and more.
3 Conclusions and Suggestions Street Light Equipment Facilities Management Geographic Information System is a module for street lighting equipment and facilities from account management, equipment and facilities image management, equipment and facilities line operation management, primary wiring diagram management, map printout, simulation operation management, street light 110, etc. Close integration, in addition, its connection with wireless monitoring systems, engineering auxiliary management systems, material management systems, etc., also makes it the core operating platform for equipment management of the street lighting management office. The streetlight management department will inevitably need and rely on street lighting equipment facilities to manage geographic information systems in future work.
The construction of GIS equipment for street lighting equipment facilities is relatively mature in technology, and there are many related systems at home and abroad that can be used for reference. This is beneficial for system construction, but this does not mean that street lighting equipment facilities manage geographic information systems. There is no difficulty in construction. In view of the speciality of GIS system construction (mainly for a large amount of pre-data preparation and data entry), the following points should be noted in the construction of GIS equipment: 3.1 line census, data collection, update and maintenance of street lighting management office equipment facility management geography The construction of information system is a systematic project for the modernization of street lamp department management. The collection and continuous updating and maintenance of data is the key to the practicality of this project. Therefore, conducting street light surveys, standardizing data collection methods, establishing data collection, update and maintenance systems, and data confidentiality systems, plus data collection inputs, are necessary and should be noted in the early stage of system implementation, and can also effectively ensure the current situation of system data. , accuracy, consistency. This stage of work is heavy and the task is arduous.
3.2 System overall planning evaluation The functions and data of other systems laid the foundation, street lamp AM/FM/such as management geography; implementation of information system has a correct guiding party t. The success or failure of a system implementation, the key is whether there is A master plan that takes overall and overall planning. The overall planning of the GIS of the street lighting equipment and facilities can only be set by the leaders of the street lighting management department, professionals and experts, and the future implementation of the street lighting equipment will not be misunderstood.
3.3 Informatization training of relevant personnel in the street lamp department In view of the low level of informatization of the street lamp industry and the low level of computer operation of relevant personnel, it is very necessary to carry out street lamp informationization training and strong GIS concept. In addition, only the information level of the staff at the street lamp is improved, which is beneficial to the industrialization of information at the street lamp.
(Continued from page 25) The number of parameters to be determined, if the parameter selection is too small, the displacement law of the foundation pit cannot be accurately revealed; if too many parameters are selected, the accuracy of the calculation will be reduced, and the observation data of the foundation pit displacement will be more The influence of various factors, the more the center point, the greater the possibility that the displacement of the center point contains gross errors. Table 3 EF foundation pit monitoring surface selection of the number of center points test results 4 Conclusion In summary, the accurate establishment of the foundation pit monitoring surface deformation model, for the timely and correct disclosure of the foundation pit deformation is of great significance. For the unsupported foundation pit monitoring surface, the displacement model should be fitted by the relatively simple quadratic function method; for the supported foundation pit monitoring surface, the displacement model should be fitted by the multi-face function method. Due to the limitation of observation conditions, coarse errors will inevitably appear in the observation data, so robust estimation must be performed in the displacement model fitting to ensure the accuracy of the deformation model. As far as the multi-face function method is concerned, its kernel function has many forms, and the selection of the number of center points should be determined according to the specific situation, which is not only related to the density and quality of the displacement observation, but also related to the size and shape of the monitoring surface. The best solution is to design the foundation pit displacement model fitting calculation software, and draw conclusions by comparing the fitting results of different center points.
