Intelligent Street Lamp with the Development of Intelligent City is the trend of the times


1. Development Trend of Intelligent Street Lamp


"Smart City" is a new type of information-based urban form formed under the support of Internet of Things information technology. It is also an important strategy for urban development at home and abroad. The Central Working Conference on Cities put forward the idea of "striving to build a smart city". Eight ministries and commissions of the state responded quickly and issued the Guiding Opinions on Promoting the Healthy Development of Smart Cities. It was proposed that by 2020, a number of smart cities with distinctive characteristics should be built. In recent years, a series of policies have landed, and the construction of smart cities has entered the fast lane. In 2017, with the implementation of smart city planning, 140 smart cities have been built nationwide, creating a huge market of more than 50 billion yuan. According to the "Special Investigation and Investment Value Prediction Report of China's Smart City Construction Market Industry 2017-2022" issued by the Smart Research Consulting Group, by 2021, the composite growth rate of the Smart City Market covering Smart City Management, Safe City, Smart Transportation, Smart Government, Smart Parking, Smart Medical, WIFI City and other functions will be about 32.64% annually in the next five years, and the market scale will be in 2021. It reached 18.7 trillion yuan. Intelligent city industry market has broad prospects. Cloud computing, big data and sensor technology and other related supporting technology fields are expected to achieve explosive growth.——intelligent Urban


As an important part of smart city, smart street lamp is one of the most effective ways to cut in, and has huge development space. As the main body of urban lighting, urban road lighting has achieved rapid growth with the rapid development of urban construction in China. According to the data of the National Bureau of Statistics, from 2004 to 2014, the number of urban road lighting lamps in China increased from 10.53 million to more than 30 million, with an average annual compound growth rate of more than 11%. The urban road lighting industry maintained a trend of sustained and rapid development. The information resources of smart cities need a large number of perception devices to collect. As the entrance end of a wise city, street lamps distribute along the city roads and streets, covering the whole city body like blood vessels and nerves. They are dense and numerous, and have the characteristics of "network, point and pole". Taking intelligent street lamps as the key node of the construction of a wise city can avoid the waste of resources caused by repeated construction, and they are the main carriers of a wise city. Intelligent street lights can expand the application of various functions of intelligent city, such as carrying intelligent lighting, intelligent new energy charging, intelligent security, safe city, intelligent city management, intelligent transportation, intelligent parking, urban WIFI and other functional modules, to provide convenient services for people's lives. It is predicted that by 2021, the market size of all kinds of hardware and services imported by smart street lamps will be 3.7 trillion yuan, accounting for 20% of the total market size of smart cities.——intelligent Urban


2.The construction of 2G and 5G micro-base stations is another important factor to accelerate the development of intelligent street lamps.


In order to meet the demand of high data traffic and high transmission rate in 5G network, 5G network has higher spectrum than 4G network. The higher the frequency, the faster the transmission speed, but it will inevitably lead to the shorter distance of wireless signal transmission. Ultra-intensive networking in the 5G era generates the demand for small base stations. At present, the deployment methods of small base stations are mainly divided into indoor coverage and outdoor coverage. The specific deployment methods of outdoor cover mainly include: pole installation, floor installation and ground installation. The installation method of intelligent street lamp is a typical way of holding pole installation, which has the advantages of power supply, intelligent management, intensive coverage, space saving, covering blind spots and so on. Compared with the frequent disputes of floor installation and property safety problems of ground installation, the installation of small base stations on smart street lamps will be one of the most feasible ways. According to the plan of IMT-2020 (5G) Promotion Group, the three major operators have basically decided to carry out 5G pilot projects in key cities in 2018 and officially open commercial projects in 2020. This will generate a huge demand for smart street lights.——intelligent Urban


3. Smart Street Lamp is the most natural Internet of Things platform in Smart City


Firstly, street lights and their systems have natural information perception and feedback platforms in smart cities. Urban street lamps have perfect and independent power supply system. Because it has the characteristics of unbalanced use and sufficient margin, it can meet the power demand of communication and information facilities without laying cables.——intelligent Urban


Secondly, network distribution is one of the most important characteristics of street lamp layout. With the increase of road network density, the characteristics of network distribution will be more obvious and reasonable, and the dead angle will gradually disappear. The network distribution of communication and information facilities without dead angle is the basic condition to realize the full coverage of information in smart cities. In all municipal facilities, only the street lamp system can realize network distribution without dead angle.——intelligent Urban


Thirdly, the height of the street lamp monomer and the capacity of the inner cavity are enough to load enough communication and information equipment with smaller and smaller volume under the requirements of integrated design.——intelligent Urban


Street lamp structure has three basic components: pole, seat and arm. In customized street lamp, there is usually a main body with unique structure. It goes without saying that the capacity of lamp holder and main body is too large, that is, lamp pole and lamp arm can also load communication and information equipment through reasonable design without affecting the beauty of its appearance. It is these three natural advantages that make the intelligent street lamp the most ideal Internet of Things platform for the development of smart cities.——intelligent Urban

Thoughts on the New Business Model of Intelligent Street Lamp


Intelligent street lamp was initially put forward in 2014. It has gone through about four years. It should be said that in recent years, the technology of intelligent street lamp has become more and more mature. From the street lamp industry to the government, they gradually understand this product, and all over the country have launched smart street lamp demonstration projects or demonstration projects, and smart street lamp is more and more widely recognized by the industry. However, the products which have multiple functions and can bring great help to the construction of smart cities have not been widely applied and promoted, mainly because the traditional street lamps only have lighting function, and the construction, management and maintenance mode of the government is relatively mature. However, intelligent street lamps have many functions, complex technology, high price, and involve many government management and use departments. How to build, how to manage and how to maintain them is a subject facing us. Especially, which business model should be adopted for large-scale construction is worth thinking and studying.——intelligent Urban


Traditional street lamps only have lighting function. Generally, the new construction is the mode of government purchasing, and the transformation to LED is the EMC (contract energy management). The intelligent street lamps have more functions, which can be divided into three categories: first, some basic equipment, such as 5G base station, and second, the intelligent management functions for government management, such as smart city management, safe city, etc. Intelligent parking, intelligent transportation, etc. Third, service functions for urban residents, such as charging piles, wireless WIFI, etc. It can be seen that because of the integration of these functions, intelligent street lights can provide more services for government management departments, social institutions and citizens. At the same time, these functions of smart street lamps need continuous operation to play their value, so smart street lamps have great operational value.——intelligent Urban


In recent years, some companies have been actively exploring the new business model of smart street lamp, that is, EMC+PPP mode, giving full play to the function and operation advantages of smart street lamp, and using EMC+user-paid mode to build large-scale smart street lamp. For example, Sichuan Huati Lighting Technology Co., Ltd. signed the "Strategic Cooperation Framework Agreement" with Shuangliu District of Chengdu City in January 2018 to transform Shuangliu District. District 30,000 intelligent street lamps, using EMC + PPP mode, 10 years of operation. Intelligent Street Lamp adopts PPP + EMC mode, while introducing new business models such as value-added business joint investment and revenue sharing. It is expected to achieve rapid replication and large-scale development in the whole country by fully docking with the total package of Intelligent City business.——intelligent Urban


In fact, the construction of intelligent street lamp system has made the traditional lamp pole have the attributes of comprehensive utilization and operation. PPP project companies can produce more operational by-products by providing public goods or services (such as maintenance) required by the government. At present, there are three main types of income from intelligent street lighting projects:——intelligent Urban


Firstly, energy-saving benefits; secondly, vertical application fees, such as information publishing-based services (LED advertising screen/pass-through induction screen), charging piles and so on, have just arisen, but these fee models have not formed the industrial scale, and there is not enough evaluation basis for matching. However, PPP projects generally require that benchmark earnings in ten or twenty years should be measured at present, so it is difficult to accurately measure them. The third category of potential revenue generation is big data. Big data is the core content of smart cities, but most of the current big data is used in the precise marketing of customers. Taking the application of wireless intelligent tourism scenic spots and business circles as an example, data acquisition based on WiFi for street lamps can be used for precise marketing and advertising promotion, and greatly enhance the economic value added of business circles. Another frequently mentioned application is monitoring and early warning. At present, urban data has not yet formed a city data mine, and in the formulation of data opening policies and data protection laws, the government needs to further strengthen.——intelligent Urban


1. Energy Conservation Benefits


The operating income of the project company mainly comes from the electricity expenditure saved by road lighting after the implementation of the project, and the social investors get the income according to the agreement with the government. According to the actual annual electricity expenditure of the road lamps involved in the project, the financial departments at the corresponding levels of the government calculate the electricity cost saved after the transformation, pay the transformation and operation cost of social capital, and pay the street lamp electricity cost from the annual budget arrangement.——intelligent Urban


2. Income from value-added applications


The government can grant the right of street lamp management to the social capitalists, by which they can tap the operation potential and obtain value-added benefits. "At present, the intelligent street lamp is operational, so it is more suitable to adopt the new mode of PPP + EMC." "For example, the fee will be charged through additional advertisements and expansion projects such as setting up cameras, environmental monitors and WIFI launching stations with street lamp poles of lighting projects as carriers." The social investors get the income according to the proportion of investment in the project company or the proportion agreed with the government.——intelligent Urban


By 2019, intelligent lighting systems using Internet of Things technology will generate about $550 billion in software and services for the industry, while hardware sales will generate only $50 billion. For LED lighting enterprises, at present, only hardware sales revenue can be shared, so how to ensure the share of this cup, at the same time, can also benefit from software and services, such as grasping all kinds of data collected through street lamps, collecting universal data processing service fees, is one of the key points that LED enterprises need to explore in the future.——intelligent Urban


The construction of new smart city can not be separated from PPP mode more and more, and the construction of smart street lamp can not be separated from the support of PPP mode. In fact, for the smart street lamp industry, it is one of the topics that must be considered that how to ensure that they can share the revenue of hardware sales and also benefit from software and services. Lighting enterprises must also think about how to obtain long-term return on investment through operation services, fully explore the application value and operation value of intelligent street lamps, in order to solve the problem of large-scale application and promotion of intelligent street lamps.——intelligent Urban
