- Apr 03, 2019-

Smart street lights with the development of smart cities is the trend of the times


1. The development trend of smart street lamps


"Smart City" is a new type of information-based urban form formed under the support of information technology of the Internet of Things. It is also a major strategy for the development of cities at home and abroad. The Central City Work Conference proposed “focusing on building a smart city”. The eight ministries and commissions responded promptly and issued the “Guiding Opinions on Promoting the Healthy Development of Smart Cities”. It is proposed that by 2020, a number of smart cities with distinctive characteristics will be built. In recent years, a series of policies have landed, and smart city construction has entered a fast lane. In 2017, with the implementation of smart city planning by the state, 140 smart cities were launched nationwide, creating a huge market of more than 500 billion yuan. According to the “Special Survey and Investment Value Forecast Report of China Smart City Construction Market in 2017-2022” issued by Zhiyan Consulting Group, by 2021, it covers smart city management, safe city, smart transportation, smart government, smart parking, smart medical care, The smart city market with functions such as WIFI city will have an average annual compound growth rate of 32.64% in the next five years, and the market size will reach 18.7 trillion yuan in 2021. The smart city industry has broad market prospects, and related supporting technologies such as cloud computing, big data and sensor technology are expected to achieve explosive growth.


Among them, intelligent street lamps, as an important part of smart cities, are one of the most effective ways to cut into the road, and the development space is huge. As the main body of urban lighting, urban road lighting has achieved rapid growth along with the rapid development of urban construction in China. According to the National Bureau of Statistics, from 2004 to 2014, the number of urban road lighting in China increased from 10.53 million to more than 30 million, and the compound annual growth rate exceeded 11%. The urban road lighting industry maintained a sustained and rapid development trend. The information resources of smart cities require a large collection of sensory devices. As the entrance end of the smart city, street lamps follow the urban roads and streets, covering the entire city body like blood vessels and nerves. They are dense and numerous, and have the characteristics of “net, a little, and pole”. As a key node in the construction of smart cities, it can avoid waste of resources caused by redundant construction. It is the main carrier of smart cities. Smart street lights can expand the functions of smart cities, such as smart lighting, smart new energy charging, smart security, and peace. Multi-functional modules such as city, smart city management, smart transportation, smart parking, urban WIFI, etc., provide convenient services for people's lives. It is predicted that by 2021, the market size of various hardware and services with smart street lamps as the entrance will be 3.7 trillion yuan, accounting for 20% of the total size of the smart city market.


2. The construction of 5G micro base station is another important factor in accelerating the development of smart street lamps.


In order to meet the high data traffic and high transmission rate requirements of 5G networks, 5G networks are higher in spectrum than 4G. The higher the frequency, the faster the transmission speed, but it will inevitably lead to a shorter distance for wireless signal propagation. Ultra-dense networking in the 5G era has spawned demand for small base stations. At present, the deployment mode of small base stations is mainly divided into indoor coverage and outdoor coverage. The specific deployment methods for outdoor coverage include: pole installation, floor installation and ground installation. The installation method based on smart street lamps is a typical way of pole-mounted installation, which has the advantages of power supply advantages, management intelligence, dense coverage, space saving, and blind spots. Installing a small base station on a smart street light is one of the most viable options compared to the frequently occurring disputes in floor installations and property safety issues on the ground. According to the plan of the IMT-2020 (5G) promotion group, the three major operators basically determined the 5G pilot of key cities in 2018 and officially opened commercial in 2020. This will give rise to a large demand for smart street lamps.


3. Smart street lights are the most natural Internet of Things platform in smart cities.


First of all, street lights and their systems have a natural information perception and feedback platform in smart cities. Urban street lights have a complete and independent power supply system. Because of its unbalanced use characteristics, the margin is sufficient, so that the power demand of communication and information facilities can be met without laying cables.


Second, the network-like distribution is one of the biggest features of the streetlight layout. As the density of the road network increases, the characteristics of the network distribution will be more obvious and reasonable, and the dead angle will gradually disappear. The networked distribution of communication and information facilities without dead ends is the basic condition for realizing full coverage of smart city information. Among all municipal facilities, only the streetlight system can achieve a network distribution without dead ends.


Again, the height and lumen capacity of the street light unit is sufficient to carry enough, increasingly small, and small communication and information equipment under the integrated design requirements.


The street lamp structure has three basic components: a pole, a seat and an arm. In a customized street lamp, there is usually a structurally unique body. The large capacity of the lamp holder and the main body is self-evident, that is, the lamp post and the lamp arm can also be loaded with communication and information equipment by a reasonable design without affecting the beauty of the appearance. It is these three natural advantages that make smart street lights the most ideal IoT platform for smart city development.


Smart street light definition and function

Integrating new energy vehicle charging piles is the best way to build distributed new energy vehicle charging stations on the road. At present, the integrated charging vehicles for new energy vehicles are generally AC charging piles with a power of 7 kW and a slow charging speed. The main energy vehicles are charged for the new energy vehicles parked on the side of the street lights. It is foreseeable that with the further increase in the number of new energy vehicles, A combination of DC charging posts and street lights with faster charging speeds will also emerge.


3.8 Urban Monitoring Components


Smart street lights integrate monitoring modules of urban infrastructure, such as manhole cover monitoring and water monitoring, which can effectively sense the state and information of urban infrastructure and provide data for various applications in smart cities.


3.9 Emergency alarm module


The integrated emergency alarm module of the street lamp can quickly transmit the alarm to the management center. The management center can observe the scene through video, and can communicate with the alarm person in real time, deal with the sudden and malicious incidents, prevent the danger from expanding, and effectively solve the problem. Safety issues in public places, to achieve a safe city.


The above is a typical representative function of smart street lights. Some manufacturers in the industry will also configure other functions such as USB charging module, remote broadcasting, information inquiry screen, etc., which will not be described here. In short, the smart street lamp is an ideal smart city IoT platform. With the development of smart city, the function of smart street lamp will be continuously updated and developed.


4, the wisdom of the smart street lamp


There are many intelligent streetlight integration functions, which connect a large number of IoT devices. Generally, each smart street lamp will be equipped with a smart gateway. This smart gateway is the intelligent brain of smart street lights, which can realize signal transmission, exchange and data collection of multiple devices. Processing, local collaboration, local data processing, and then passed to the cloud for data processing, is an edge computing device that works with the cloud.


5. Software management platform for smart street lights


Smart Street Light integrates a variety of smart devices and sensing devices. It needs a unified cloud management software platform to manage multiple devices, collect data, and implement collaborative work based on different application scenarios. The unified cloud management software platform needs to realize the management functions of intelligent lighting, video monitoring, multimedia information release, environmental monitoring, emergency alarm, manhole cover monitoring, wireless WIFI, charging pile management, etc., and should also implement big data display, multi-subsystem linkage, etc. Features.


Smart Street Light integrates many functions, it is not only a separate system, but also needs to apply these functions to various scenes in a smart city, in order to fully play the role of these functions, and form a perfect connection with smart city applications. Here are some comparisons. Typical smart street lights are applied to smart city scenes.


1, the application of smart parking


The smart recognition camera integrated on the smart street lamp can effectively recognize the car entering and leaving the parking space, and recognize the license plate during the parking process, and transmit the identification information to the cloud for processing. Then use the LED display integrated on the smart street lamp to induce the parking space information. The identification range of a smart camera is 6~8 parking spaces, about 35 meters, which is just the distance between two street lights. Therefore, using smart street lights, It is one of the ideal applications to realize smart parking in urban roadside parking lots.


2, the wisdom of urban management applications

Thoughts on the New Business Model of Smart Street Lights


Smart streetlights have been proposed since 2014. Today, it has been going through about four years. It should be said that in recent years, smart streetlight technology has become more mature. From the streetlight industry to the government, we have gradually learned about this product. Various localities have also launched smart streetlight demonstration projects or demonstration projects. Smart street lamps are increasingly recognized by the industry. However, such a product that combines multiple functions and can greatly help the construction of smart cities has not been widely applied and promoted, mainly because traditional street lamps only have lighting functions, government construction, management, The maintenance model is relatively mature. However, there are many smart street lamps with complex functions, high prices, and a large number of government management and use departments. How to build, how to manage, and how to maintain them is a topic that is faced with, especially, which business model is used for scale construction. Worth thinking and research.


The traditional street lamp only has the lighting function. Generally, the new construction is the government procurement mode, and the LED is the EMC (contract energy management mode) adopted. The smart street lamp has more functions, and can be divided into three categories according to the functional attributes. : First, some basic equipment, such as 5G base stations; second, smart management functions for government management, such as smart city management, safe city, smart parking, smart transportation, etc.; third, service functions for urban citizens, such as charging piles, Wireless WIFI and so on. It can be seen that because of the integration of these functions, smart street lamps can provide more services for government management departments, social organizations, and citizens. At the same time, these functions of smart street lamps require continuous operation to bring value. Therefore, smart street lamps have great operational value.


In recent years, the company has been actively exploring new business models for smart street lamps, namely, adopting the EMC+PPP model, giving full play to the functional operation advantages of smart street lamps, and adopting the EMC+user payment model for large-scale construction of smart street lamps, such as Sichuan Chinese Lighting Technology Co., Ltd. signed the "Strategic Cooperation Framework Agreement" with Chengdu Shuangliu District in January 2018. It plans to transform 30,000 smart street lights in Shuangliu District, adopting EMC+PPP mode and operating period of 10 years. Smart Street Light adopts PPP+EMC mode and introduces new business models such as value-added business joint investment and revenue sharing. It will be fully integrated with the general package smart city business, and it is expected to achieve rapid replication and large-scale development in the country.


In fact, the construction of the intelligent street lamp system has made the traditional light poles have the attributes of comprehensive utilization and operation. PPP project companies can produce more operational by-products when they provide public goods or services (such as maintenance) that the government needs. At present, there are three main types of project benefits for smart streetlights:


First, energy-saving benefits; second, vertical application charges, such as information-based services (LED advertising screen / pass-through screen), charging pile charging, etc., but such charging models have just emerged, have not yet formed an industrial scale, not enough The evaluation is based on matching. The PPP project generally requires that the benchmark earnings within ten years and twenty years be measured, so it is difficult to accurately measure. The third type of revenue that can generate revenue 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 merchants. Taking wireless smart tourist attractions and business district applications as an example, data collection based on WiFi in street lights can be used for precision marketing and advertising push, which greatly enhances the economic value added of the business district. Another commonly mentioned application is monitoring early warning. At present, urban data has not yet formed urban data mines, and the government needs to further strengthen the development of data open policies and data protection laws.


1. Energy saving income


The operating income of the project company mainly comes from the electricity expenses saved by road lighting after the implementation of the project, and the social investors obtain the income according to the agreement with the government. The government's financial department at the same level shall calculate the electricity cost saved after the transformation according to the actual annual electricity expenditure of the road lamps involved in the project, pay for the transformation and operation cost of social capital, and pay from the annual street lamp electricity fee.


2. Value-added application revenue


The government can grant the right to operate street lamps to the social capital side, which can tap the operational potential and gain value-added income. “Current smart street lights are already operational, so they are more suitable for adopting the new PPP+EMC model.” “If you add advertising and set up a camera with a lighting pole for the lighting project, the environment monitor, WIFI launch station and other expansion projects to collect fees. Social investors receive income based on the proportion of investment in the project company or the ratio agreed with the government.


By 2019, intelligent lighting systems using IoT technology will bring about $550 billion in revenue to software and services, while revenue from hardware sales is only $50 billion. For LED lighting companies, only the hardware sales revenue can be shared at present, so how to ensure the share of this cup, but also the software and services, such as grasping the various data collected through the street lights, The cost of collecting general data processing services is one of the key points that LED companies need to explore in the future.


The construction of new smart cities is increasingly inseparable from the PPP model. The construction of smart street lamps is inseparable from the support of PPP mode. In fact, for smart street lamp manufacturers, how to ensure the sharing of hardware sales revenue can also be in software and There are gains in services, which is one of the topics that must be considered. Lighting companies must also think about how to obtain long-term investment returns through operational services, fully explore the various application values and operational value of smart street lamps, in order to solve the problem of large-scale application and promotion of smart street lamps.
