What are the advantages of smart solar street lamps over conventional LED street lamps?
Smart city has become a concept of urban development, which is highly valued by governments at all levels and all sectors of society.
100% of sub-provincial cities, 89% of prefecture-level cities and above, and 49% of county-level cities have started smart city construction, with the total number of participating prefecture-level cities reaching more than 300.
The smart city planning investment reached 3 trillion yuan, and the construction investment reached 600 billion yuan.
For example, Shenzhen plans to invest 48.5 billion yuan, Fuzhou 15.5 billion yuan, Jinan 9.7 billion yuan, Xizang Xigaze 3.3 billion yuan, Yinchuan 2.1 billion yuan.
Smart solar street lamp, smart lighting and smart city are not new concepts for a long time, but with the support of policies, 5G tuyere and the maturity of technology, smart outdoor lighting will usher in another spring of lighting.
Therefore, the market layout of smart solar street lamps in 2020 is bound to be a precise layout of outdoor lighting in the future.
I. Current situation of intelligent street lamp technology
At present, the interconnection technologies used in smart street lamps mainly include PLC, ZigBee, Sigfox, Lola, etc. These technologies cannot meet the "interconnection" demand of street lamps distributed everywhere, which is one of the key reasons why smart solar street lamps still fail to be deployed on a large scale.
PLC, ZigBee, Sigfox, Lora and other technologies need to build their own networks, involving investigation, planning, transportation, installation, testing and optimization, etc., and need to maintain the network after the construction, so it is not convenient and efficient to use.
Network deployment using PLC, ZigBee, Sigfox, Lora and other technologies has poor coverage, vulnerable to interference and unreliable signals, leading to low access success rate or easy connection drop. For example, ZigBee, Sigfox, Lora and other technologies use unauthorized spectrum, resulting in large interference in the same frequency, very unreliable signals, limited transmission power and poor coverage.
And PLC power line carrier often exists more harmonics, signal attenuation fast, so that PLC signal instability, poor reliability.
Third, these technologies are either old and need to be replaced, or proprietary and less open.
For example, although PLC is the earlier launch of the Internet of Things technology, but there are technical bottlenecks that are difficult to break through, such as it is difficult to cross the distribution cabinet to expand the control range of the centralized controller, so the technological evolution is also limited;
ZigBee, Sigfox and Lora are mostly private protocols, which are subject to many restrictions on the openness of standards.
Although 2G(GPRS) is a public network of mobile communication, it is currently in the process of unnetworking.
Two, the main functions of intelligent solar street light
1. Integration and systematization of intelligence functions;
2. Intelligent control, intelligent regulation, real-time data transmission of energy consumption;
3. Smart data collection terminal, hub center and data platform;
All things network connection;
5. Safety warning + information release;
6, urban flow identification;
7. Signal base station;
8. Monitoring base station.
That is to say, smart solar street lamps are the largest entrance to the current and future smart cities. Combined with the urbanization block segmentation of roads and buildings, they have become the function and collection hub with the largest number, the most extensive distribution and the most convenient application.
3. Today's smart solar street lamps are just like the conventional LED street lamps of 2011
At that time, many traditional outdoor lighting manufacturers are wait-and-see, try.
Even many industry experts are still discussing that due to the production process, illumination and other reasons, LED street lamps are not suitable for mass application. With the help of the characteristics of LED modules and EMC energy management, LED street lamps suddenly burst into market competitiveness.
Some of today's well-known outdoor lighting enterprises are almost in that year's market competition, accurate card position, stand out.
4. The development of new technology lays the foundation for the development of smart solar street lamps
With the completion of 5G commercial use in China in 2020, smart solar street lamps will become the "web celebrity star" in the market, forming a scale market of 100 billion yuan.
Internet, cloud computing, Internet of things information, data of the basic application.
It has opened the door to smart cities. The introduction and support of regional government policies have solved the problems of market demand and the implementation of systematic and integrated construction in various fields.
Lighting pole manufacturing, lighting technology, Internet of things technology, communication and display technology effective integration.
The overall scheme is mature and accelerates the construction of intelligent outdoor lighting.
As mentioned above, smart outdoor lighting has become the core module of future city construction. Therefore, the current hardware technology, software technology, supply management and market layout of smart solar street light have become the key cards for outdoor lighting in the next 10 years
