“The street light will adjust the switch light time according to the position of the light. We also handle the 'ID card' for each street lamp, and record its attribute information in detail; if the street lamp and cable are faulty, the system will automatically alarm and promptly Inform the maintenance personnel to deal with..." At the Urban Lighting Management Office of Jiangbei District, Chongqing, the lighting monitoring center staff introduced the operating system.
Jiangbei Urban Lighting Integrated Management System
Recently, with the advancement of the construction of smart city management in Jiangbei District, the urban lighting integrated management system independently developed by the district has entered the trial operation stage. According to reports, the newly-introduced urban lighting integrated management system mainly consists of lighting monitoring and management platform, lighting facility asset GIS management system, maintenance process (task) management system, intelligent lighting decision support system, automatic generation of various facility accounts, and provision The lighting rate and the facility integrity rate account, single lamp control management system, urban lighting mobile operation and maintenance operation system, vehicle GPS monitoring management system, video monitoring system and warehouse material management system are composed of nine sections. Using mobile internet technology to monitor, detect and debug lighting equipment in real time, realize remote control and management of important roads and urban road lighting equipment within the jurisdiction, and help to realize urban lighting from management to service, from governance to operation. From fragmentation to synergistic revolutionary transformation.
Then, when the street lamp meets the Internet, what kind of "smart spark" will collide?
"Time Control" changed to "Light Control" to greatly improve the power saving rate
Through the use of this system, the street lighting and landscape lighting in Jiangbei area will realize "light control", and the system will adjust the time of "lighting and turning off" according to different seasons and weather conditions.
Li Bin, deputy director of Jiangbei District Urban Lighting Management Institute, firstly, the daylighting device will automatically collect the real-time light value in real time, and automatically evaluate and analyze the most reasonable lighting and light-off “threshold value†when the external light reaches the “threshold valueâ€. The "switch light" command is sent to the terminal lighting through the system. “Traditionally, by setting the time to control the opening and closing of the lighting, the point is bright, and the point is extinguished. This can not cater to the changes of the weather and the season. The light control can meet the reasonable lighting needs in different seasons. Greatly improve the power saving rate, and effectively solve the problem of street lighting." Li Bin further explained that if the sunny day lighting time is around six o'clock, that is, the light "threshold" is reached at this time, if it is rainy, the light becomes weak. , the "threshold" will be reached in advance, and the time for lighting will be automatically advanced.
In addition, the system will automatically generate light values ​​according to the “latitude and longitude†of the region, and in the case of “light control†failure, send commands to the terminal to ensure the normal operation of the street lamps.
Building lighting facilities, large database street lights have "ID card"
The staff opened the lighting facility asset GIS management system, and a map of the lighting facilities in Jiangbei District came into view. In the search window, the keyword “Haier Road†was entered. The map then jumped to the Haier Road area, and the map was enlarged by mouse to find Haier. All the street lights, click the icon of the corresponding street light to view the detailed properties of the street light.
"The lamp we are seeing now, number 050021056, belongs to Haier Road No. 1 box distribution box, LED light type..." The staff introduced that the street lamp number is unique and contains a lot of information. For example, "02" of the lamp means that the circuit to which it belongs is "2", similar to the ID number of the resident. The system also records in detail the circuit, road information, distribution box, lamp type, number of lamps, control method, real-life photos and manufacturers of each lamp. Each street lamp has the same “ID cardâ€.
Every street lamp has its own "ID card", which is clear on the system.
It is reported that Jiangbei District has started the basic data collection of street lamps since June last year. The scope of the census includes the location survey of the main street lamps under the jurisdiction of the Jiangbei District Street Light Management Office, the location change of the box and the starting and ending points of the line circuit, and the crossing of the street pipeline. Positioning census, generally the light pole, power point and loop as the basic census unit, and the detailed data of the location census is entered into the GIS management information system. By completing the collection, verification and processing of lighting geographic information data, the lighting business information map is realized, and the lighting geographic information and business information coding library, the lighting basic geographic information database, the lighting asset attribute information database, the lighting business dedicated database, real-time and real-time A unified lighting geographic information database including historical dynamic information database and graphic symbol library.
"At present, we have completed more than 6,000 street lamp information collection, and will gradually complete the data collection of nearly 20,000 lamps in the jurisdiction. Building a lighting facility database not only facilitates the inquiry and maintenance of lighting facilities, but also the subsequent business system construction. Provides basic data, and at the same time, supports subsequent facility expansion and fine-grained management of attributes." Li Bin said.
System diagnosis "disorder" fault detection becomes intelligent
Street lamp fault detection is a time-consuming and laborious task in urban management. Jiangbei District relies on the urban lighting integrated management system and introduces the street lamp fault intelligent detection instrument, which effectively solves the problem of street lamp fault detection and makes the street lamp maintenance management process more intelligent.
At Haier Road, the staff of the Jiangbei District Urban Lighting Management Office demonstrated the process of street lamp fault detection. The staff is armed with a street light fault detector and is monitored on the ground near the street light. The "health" condition of the underground line is judged by the change of the pulse frequency displayed by the detector. “If there is a fault in the underground line, the pulse frequency will be abnormal. The street lamp fault intelligent detection system can accurately detect the position of the street lamp line fault without excavating the ground.â€
After completing the troubleshooting, the patrol personnel immediately opened the urban lighting integrated management system, and reported the fault details to the operation and maintenance operation system through the work order reporting function. According to Li Bin, the maintenance process (task list) management system is one of the most important sections of the system, mainly used for maintenance and process management. After the field patrol personnel finds the facility fault information on site, the fault information is uploaded through the system, and the lighting monitoring center attendant will create a new work order, indicating the source of the fault, the fault location, the repairer, etc., and dispatch it to the maintenance team to maintain the team. After the completion of the inspection and completion of the processing, and then feedback to the duty officer, the duty officer closed the case, the whole process is clear and clear.
In addition to the staff going out to inspect the fault, the system can also automatically detect the "disease". When the street lamp voltage, current, etc. are abnormal, the system will alarm and send the fault information back to the system, automatically generate a work order, and apply for repair processing. "System intelligent maintenance, efficient and accurate, reducing the pressure for manual inspection, greatly improving the efficiency of troubleshooting. In addition, each road lamp is pasted with the 'two-dimensional code' of identity information and the street lamp monitoring center telephone, the public If you find that the street lamp is faulty, you can also scan the QR code to get the information of the street lamp and call for repair." Li Bin said.
"Smart City Management" lights up wisdom Jiangbei
As an important part of the construction of smart city management in Jiangbei District, the official completion of the urban lighting comprehensive management system marks that the urban lighting management of Jiangbei District has entered a new era of smart management, and is also of great significance to the promotion of Jiangbei smart city management.
It is reported that the Jiangbei District Smart City Management Platform consists of 19 main systems and 84 subsystems, which are completed in three phases. The platform uses big data, cloud computing and full-service integration system as the core engine to accept complaints and suggestions from the masses to the city management work in real time, and to conduct urban management law enforcement, environmental sanitation, municipal facilities, lighting lighting, parking guidance, etc. The integrated management of the information system was officially launched in August 2016.

In the smart city management platform, it is not only urban lighting management that is injected into the "Internet Gene". The urban underground drainage pipe network information system put into use is equipped with professional equipment such as pipeline CCTV detection robot, pipeline profile sonar imager, ground penetrating radar, drainage pipeline inspection vehicle, etc., which can provide more scientific and effective technical means for dredging work; The parking system integrates the three subsystems of parking lot induction, in-street intelligent parking and indoor parking charge supervision with public security dynamic traffic information to effectively alleviate the difficulty of parking.
“In recent years, Jiangbei District has actively carried out the construction of smart urban management, innovated in various aspects such as comprehensive management of municipal facilities and monitoring of hazard sources, and achieved a series of results. It has effectively improved the ability of municipal departments to actively discover and solve urban management problems. To bring more convenience to the people's life. In the next step, we will speed up the construction of smart city management, and let Jiangbei city management 'ears know clearly'," said Jiang Li, director of the Jiangbei District Urban Management Bureau.
