A brief discussion on the relationship between lighting and smart cities

A city is a huge and complex system. The engineering infrastructure, social infrastructure and green ecological infrastructure that the city relies on for survival and development support the smooth conduct of various economic and social activities in the city, as well as the supporting operation mechanism and management system, which constitute the city's huge functional service system. Let's follow the mobile phone portable editor to learn about the relevant content.

 The so-called "smart city" can be summarized into the following three points:

(1) The construction of smart cities must be based on the application of information technology. Smart cities can be considered as the advanced stage of urban informatization, which inevitably involves the innovative application of information technology, and information technology is centered on and represented by emerging hot technologies such as the Internet of Things, cloud computing, mobile Internet and big data.

(2) A smart city is a complex, interactive system in which information technology and other resource elements are optimally configured and work together to enable the city to operate more intelligently.

(3) Smart cities are an emerging model of urban development. Smart cities serve urban entities—governments, enterprises, and individuals. Their result is the transformation, improvement, and perfection of urban production and lifestyles, and ultimately, a better urban life for humans. [1]

To sum up, the essence of a smart city lies in the high degree of integration of informatization and urbanization, and it is a manifestation of the development of urban informatization to a higher stage.

The Central Committee of the Communist Party of China and the State Council issued the [National New Town Planning (2014-2020)]. It clearly proposed that the construction of smart cities should coordinate the material resources, information resources and intellectual resources of urban development, promote the innovative application of new generation information technologies such as the Internet of Things, cloud computing, and big data, achieve deep integration with urban economic and social development, and promote the goals of smart city planning and management informatization, infrastructure intelligence, convenient public services, modern industrial development, and refined social governance.

A city is a huge and complex system. The engineering infrastructure, social infrastructure and green ecological infrastructure that the city relies on for its survival and development support the smooth conduct of various economic and social activities in the city. There are also supporting operating mechanisms and management systems, all of which constitute the city’s huge functional service system.

The top-level design of a smart city involves in-depth analysis and research on the strategic positioning, urban characteristics, resource conditions, population composition, and pillar industries of the city. The goals and construction plans formulated on this basis are also more targeted.

Smart city planning not only has hardware indicators such as advanced technology, comprehensive functions, and high performance, but also needs to innovate in the soft environment, such as system, environment, supporting mechanism, policy measures, business model, etc. Without the support of the soft environment, it is likely to follow the old path of traditional informatization and fail to reach the level of smart city.

At the macro level, the demand analysis of smart cities is to strengthen the trend analysis of the development direction and management model changes of modern cities, explore the future form of cities and the transformation of public needs. Secondly, starting from the city's development strategic goals, urban positioning, industrial positioning, and cultural characteristics, deeply analyze the social livelihood, urban management, and industrial economy's demands for digitalization, networking, and intelligence.

At the micro level, for urban infrastructure management and urban functional services, on the basis of clarifying the evolution of the capabilities of each functional module of the city, the embedded improvement effect of informatization on each functional module is analyzed.

A smart city considers the city as an organic whole, takes people as the center, and flexibly schedules and allocates various urban resources.

A scientific and reasonable construction model and an operation model after completion are important guarantees for the successful realization of smart cities. In a service-oriented society with consumption upgrades and rapid expansion of public service needs, the era of relying solely on the government and a few government-designated service providers to fight alone has long passed. Service platformization and the participation of the whole society to reconstruct the city's public service and governance system is the future development direction.

2 Urban lighting

2.1 “Smart City” needs to have four major characteristics

A "smart city" needs to have four major characteristics, namely, comprehensive and thorough perception, broadband ubiquitous interconnection, intelligent integrated applications, and people-oriented sustainable innovation.

(1) Comprehensive and thorough perception

Through sensing technology, we can monitor and perceive all aspects of urban management. Smart cities use all kinds of sensing devices and intelligent systems anytime and anywhere to intelligently identify and perceive all-round changes in urban environment, status, location and other information, integrate, analyze and process the sensing data, and integrate it with business processes intelligently, and then actively respond to promote the harmonious and efficient operation of various key systems in the city.

(2) Broadband Ubiquitous Interconnection

The development of various broadband wired and wireless network technologies has provided the basic conditions for the comprehensive interconnection, intercommunication and interaction between things, people and things, and people in the city, and for various applications in the city at any time, anywhere, on demand and at will. Broadband ubiquitous networks, as the "neural network" of smart cities, have greatly enhanced the ability of smart cities as adaptive systems to obtain information, provide real-time feedback, and provide intelligent services anytime and anywhere.

(3) Application of Intelligent Fusion

Modern cities and their management are a kind of open, complex and huge system. The application of a new generation of comprehensive perception technology has increased the massive data of the city. It should be integrated into wisdom. Based on cloud computing, the storage, calculation and analysis of massive data are realized through the application of intelligent fusion technology, and the comprehensive integration method (comprehensive integration seminar hall) is introduced to greatly enhance the decision-making support capabilities through the participation of human "wisdom". The Dacheng Wisdom Project based on the cloud computing platform will constitute the "brain" of the smart city. The integration and development of technology will further promote the combination of "cloud" and "end", promote the development from personal communication, personal computing to personal manufacturing, and promote the realization of intelligent integration, anytime, anywhere, on demand and random applications, further highlighting the participation of individuals and the power of users.

(4) People-oriented sustainable innovation

The next generation of innovation for the knowledge society has reshaped the people-oriented connotation of modern science and technology, and has also redefined the role of users, the value of applications, the connotation of collaboration, and the power of the masses in innovation. The construction of smart cities pays particular attention to the creation of open innovation spaces that are people-oriented, citizen-participated, and socially collaborative, as well as the creation of public value and unique value. It focuses on starting from the needs of citizens and strengthening user participation through tools and methods such as wikis, Weibo, Fab Lab, and Living Lab, gathering public wisdom, and continuously promoting user innovation, open innovation, mass innovation, and collaborative innovation, so as to achieve sustainable economic, social, and environmental development with a people-oriented approach. [2]

2.2 Some projects of smart city construction

(1) Smart public services: Build smart public services and urban management systems to improve urban operation efficiency and public service levels while promoting the transformation and upgrading of urban development.

(2) Smart society management: Improve the construction of public service platforms for the public.

(3) Accelerate the construction of public service platforms for enterprises.

(4) Smart housing services.

(5) Smart education and cultural services.

(6)Smart service applications.

(7) Construction of a smart health care system.

(8) Smart transportation. Build a "digital transportation" project. Through technologies such as monitoring, surveillance, and traffic flow distribution optimization, improve the monitoring systems and information network systems of public security, urban management, and highways, and establish a unified intelligent urban transportation comprehensive management and service system with a focus on traffic guidance, emergency command, smart travel, taxi and bus management, so as to achieve full sharing of traffic information.

(9) Focus on building a public service information platform for new rural construction.

(10) Actively promote the construction of smart security control systems. Make full use of information technology, improve and deepen the "Safe City" project, deepen the intelligent construction of social security monitoring dynamic video systems and data mining and utilization, integrate public security monitoring and social monitoring resources, and establish a grassroots social security comprehensive management information platform; actively promote the construction of smart security systems such as the municipal emergency command system, emergency public event warning information release system, natural disaster and flood control command system, and key production safety prevention and control system; improve the public safety emergency response mechanism, realize comprehensive command and dispatch of multiple departments in a coordinated manner, and improve the prevention and emergency response capabilities of various accidents, disasters, epidemics, cases and emergencies.

(11) Build an integrated information management platform.

The realization of the above functions must be based on infrastructure such as big data, cloud computing, the Internet, and the Internet of Things. The most critical of these is broadband ubiquitous interconnection.

2.3 Advantages of street light poles

In urban lighting, street lighting is the most direct function to ensure urban safety. Its characteristics are:

(1) Wide distribution: Like the blood vessels of a city, they fill every corner of the city.

(2) Uniform arrangement: Distributed approximately every 30 meters on the road.

(3) Fixed location: has its own unique geographical coordinates and number.

(4) Built-in power supply: to ensure the normal use of various accessories.

(5) Easy maintenance: There is a dedicated maintenance organization.

(6) Clear property rights: owned by the government.

As a unique social resource of the city, it has been neglected and has not played its due role. The construction of smart cities will give street light poles a new mission.

3 Smart City Infrastructure - Street Light Poles

In summary, the construction of smart cities cannot be separated from the most basic data transmission system. Currently, the most widely used data transmission methods are optical fiber and wireless, and optical fiber is undoubtedly one of the most reliable methods. Its optical fiber laying cost and maintenance cost are also the lowest.

With optical fiber, we can give the light pole countless functions:

(1) With the use of smart street lights, street lights can be managed in a refined manner. The operating status of street lights can be monitored in real time, including (power, voltage, dimming, life, maintenance dispatch, etc.).

(2) With the help of monitoring equipment, it is possible to understand the real-time road conditions, provide real-time road condition records to the transportation department, issue traffic warnings in a timely manner, and provide relevant information and warnings in terms of social security and public order.

(3) Cooperate with mobile communication companies to provide micro base station services and achieve full city coverage of wireless networks within a certain period of time.

(4) Use sensor technology to detect the environment, weather, climate, etc. Set up new blind paths to ensure the safety of blind people.

(5) Use tools and methods such as Wikipedia, Weibo, Fab Lab, and Living Lab to strengthen user participation and achieve sustainable economic, social, and environmental development with a people-oriented approach.

In short, all the projects listed in the smart city construction section can be achieved by using street light poles.

4 Operational Innovation

The most effective way to solve the sharing and collaboration problems of smart cities is through laws and regulations. The policy and legal system must break the original single, one-way, and static governance ideas, boldly reform and innovate, and escort the smart construction and operation of cities. Regions with conditions can make full use of local legislative power to promote city-level data sharing and business collaboration through legislation.

We advocate that the government provide the stage, enterprises perform, and government, enterprises, academia and research institutions actively participate to jointly create a new world for smart cities.
