The 'light poles' of the future are the nodes of smart cities

　　Reporter: The colorful night scene is the beautiful scenery of Shanghai and the city's name card. From the “light inside and outside” project of the last century to the static and moving lights of the Bund, and the light shows in various large-scale events, lighting has always been Shanghai’s strengths, but actual visits revealed that there still seem to be many details that have not been taken into account. problem.

　　Halosi: City lights are more than just landscapes. Megacities have always attached great importance to the landscape lighting of landmark areas, and image building is also needed. But the depth to the hinterland, residential areas, small roads, deep inside alleys and even the interior of the community are also part of the urban lighting, and the attention of this part of the functional needs is not enough at present.

　　 such as visual comfort, safety at night, the convenience of traveling for the elderly and children, and the impact on people’s health. These dimensions also need to be paid attention to.

　　Reporter: From the perspective of the city as a whole, how to evaluate the lighting project?

　　Halosi: Shanghai is so big, it is impossible to create such a rich light environment in every space, such as The residential area mainly meets the needs of traveling and walking, and the commercial area mainly meets the consumption needs of the night economy. The central city landmarks such as the Bund and Lujiazui have more functional levels, and they also shoulder the mission of showing the image of the city to the world. Different regions have different demands and cannot be generalized.

　　Yang Yun: The 'Shanghai City Landscape Lighting Master Plan' released in recent years aims to coordinate the city’s night scene layout, and determine whether the brightness and color temperature of different areas and different types of buildings can be used for dynamic lighting and color lighting. , Light pollution control, etc. are all coordinated.

　　There are many bright spots, such as “controlling the total amount of landscape lighting”, the overall layout “one city with multiple stars, three belts and multiple spots”, and the Dongtan Bird Nature Reserve prohibits the installation of landscape lights. Each district also has its own image display space, which can plan night tour routes and create representative scenic spots.

　　 However, from planning and design to landing, there is an iterative update process.

　　Reporter: Another difficulty is that for lighting, different people have different needs, and different management departments have different management angles. What should I do if there is a conflict?

　　Yang Yun: Refinement Management can avoid many contradictions from the source.

　　 For example, monitoring fill-in lights, in low-crowded areas, slow-moving areas, car-traveling areas, different roads and different interfaces, different standards should be formulated, not the same. The traffic area can also be subdivided into main roads, secondary roads, and branch roads. But let alone the new thing of supplementary light, there are currently grading standard functional lighting, and there is still no refined classification in follow-up maintenance and management.

　　Reporter: With the concept of 'smart city' and 'urban brain' taking root in the hearts of the people, the importance of light poles is no longer just 'lighting'.

　　Yang Yun: Shanghai is doing the overhead line into the ground project, multi-pole integration. As a carrier of strong and weak current equipment, light poles can integrate functions such as camera monitoring, environmental monitoring, traffic indications, and information feedback. They are also used as charging piles abroad. In the future, it will become an integrated platform that can intelligently integrate urban space and resources with unlimited possibilities.

　　 In the next step, it is a general trend to upgrade and iterate in the direction of intelligence and digitization of the joint project. The light pole may no longer be a light pole, but a basic carrier, a node of urban wisdom, from data collection, detection, release to feedback, so its location layout and route optimization cannot be considered only from the perspective of 'lights'.

　　 Moreover, city lights need to be updated and fine-tuned every 5 years, which changes with the development of the city. For example, the planning and construction of 'five new cities' has been proposed recently, so night lighting planning is particularly important for the new city, which involves factors such as pedestrian flow, image display area, and consideration of key landscape functions.

　　 At present, the refined management of lights has been multi-headed and complicated. The future smart 'combinationIncluding which smart content is integrated, which management departments are involved, and how to collaborate, manage and maintain between departments. It is a complex process and system from top to bottom that tests the governance capabilities of each city.
