Light up the road, play "beautiful" City

Street lamps, known as the city's eyes, a city silent business card. In order to make the eyes more clear, business cards more beautiful, in the first half of this year, Jiangsu City, Nantong Province Audit Bureau implemented the Nantong urban lighting management performance audit. The audit covers street lighting, landscape lighting and 399 residential areas into the management of lighting, and conducted a random sampling and monitoring of the 62 sections. Audit results show that street lights not only facilitate the public to travel, but also to make the city of Nantong night more beautiful.

Repair, ensure the satisfaction of the public

Let people travel satisfaction is the highest purpose of street lighting. The auditors choose different crossing, random to car, bicycle, walking as the main way of travel of 100 people to conduct a questionnaire survey. Among them, the brightness of the street lamp, switch lamp time satisfaction rate was 98%, the landscape lamp brightness satisfaction rate was 99%, the time of the landscape lamp switch lamp satisfaction rate was 100%.

The audit noted that the public satisfaction is so high, because the municipal government attaches great importance to street lighting, street lamp fault anywhere through 12345 government hotline, public telephone repair, digital city management and post scan two-dimensional code and other ways in the first time feedback to street maintenance management, repair personnel arrived at the scene less than 30 minutes, no special reason that night lighting maintenance safety recovery; ram, wires exposed and so on, the first time to go to the scene. Audit also learned that in 2015 the annual maintenance 16336 times, the same day the troubleshooting of the 9347, accounting for the total number of 57%. Emergency troubleshooting with a relatively short time, the number of urban management, public repair phone, 12345 platform repair, maintenance of micro platform repair on average only 2.2 days, of which the day to complete the total number of accounts for 24%. In 2015, the lighting rate and the lighting rate were kept at 98% and above, and the normal operation of urban lighting facilities was ensured.

Energy saving, advocate green lighting

Not only to run the horse, but also to eat less horse, which is the most image management requirements. In order to better reflect the idea of saving energy and reducing consumption of green lighting, the use of variable power ballast in Nantong urban area to achieve power saving in the middle of the night, reducing power supply voltage and other technologies. After the audit of the use of energy-saving technology, energy consumption was measured, the actual power consumption in 2015 than the theoretical power consumption savings of 16%. Since 2014, some of the roads and residential pilot project implementation audit LED light source, random test with LED lamp section, high pressure sodium lamp 180W LED to replace 250W, the power is reduced by 28%, the average illuminance still meet the design standards.

At the same time, the audit staff through the night field testing, found some sections according to the standard set to turn off the light illumination, or lights ofearlier time is bright daylight resulting in a waste of power resources, or to turn off the lights dim ofearlier time weather risks formation the safety of public travel. To this end, it is recommended to strengthen the audit of road lighting, power density and other indicators of monitoring, the level of illumination to improve the standard, to further improve the urban environment. At the same time, energy-saving recommendations raised by the audit quickly get feedback, Nantong 5A level scenic spots, scenic landscape has all the Haohe bridge to replace the LED light source, LED lamp replacement lamps gradually promote high energy consumption and low efficiency, to residential pilot 400 30W power LED 70W power source to replace the lamp, can save electricity nearly a year 800 thousand yuan.

Innovation, personality and wisdom

The function of urban lighting is not only "bright", but also "beautiful", which can reflect the cultural heritage of the city to a certain extent. The audit staff field survey of the lighting effect of new major projects in the past three years, found that part of the road, not the lighting design of commercial pedestrian street, the elevated road completely with the Nantong city culture positioning organically, can not reflect the cultural characteristics of Nantong. The main reason is that the construction of the construction unit and the street management department is not in place. To this end, the audit suggested that the City Lighting Department to intervene in advance, from the lamp pole, the choice of lamps and lanterns, and strive to reflect the characteristics of Nantong.

According to the audit found the single function, the utilization rate is not high, the use of extensive audit recommendations Street distribution, from Shanghai, Hangzhou, Suzhou and other places of pilot experience, exploring the lampposts integration of 4G micro base stations, multimedia information screen, charging pile, security monitoring camera, public broadcasting, wireless Wi-Fi and other functions with the wisdom of city construction, realize the data interaction under the environment of intelligent lighting, intelligent transportation, wireless city, smart city management information dissemination and other core functions.

Recently, the city's Lighting Department has adopted audit recommendations, to proceed with the transformation of functional lighting, landscape lighting for some of the beautiful. In the near future, a more in line with the modern city of Nantong cultural characteristics of the city lighting will be a new attitude in front of the public show.
