With the continuous development of human society, cities will carry more and more people in the future. At present, China is in a period of accelerated development of urbanization, and the problem of "urban disease" in some areas is becoming more and more serious. In order to solve the problem of urban development and achieve sustainable urban development, the construction of smart cities has become an irreversible historical trend of urban development in the world.

The purpose of building a smart city is to make urban facilities more intelligent, services more convenient, management more refined, and effectively improve the quality and level of urbanization development. In the process of construction, through 5G Internet of things, cloud computing, big data and other new generation of information technology innovation and application has become the mainstream. This time, Changzhou Development of Internet of things Intelligent hardware system Co., Ltd. will focus on the interpretation of the intelligent street lamps of the Internet of things in the smart city, and analyze its application scenarios and industry pain points.

The difficulty of management and maintenance has become the core pain point in the field of intelligent street lamps.

With the advent of the era of IoE and Smart Internet, the demand for Smart Street Lamp Internet is becoming more and more exuberant. According to data from the relevant research structure, the market space for the transformation of smart street lamps will reach 9.1 billion US dollars by 2025. At present, the main challenges in the field of intelligent street lamps are:

one。 Management: how to connect street lamps to the network conveniently, efficiently, safely and reliably

two。 Maintenance: how to do preventive maintenance based on single lamp positioning and big data

three。 Energy consumption: how to save energy and reduce emissions and reduce the energy consumption of street lamps

four。 Construction: how to build a platform with street lamps and smoothly evolve to a smart city.

At present, the access solutions of street lamps are mainly based on two sets of schemes controlled by protocols such as PLC/Zigbee, but there are the following problems:

one。 Poor security and reliability: niche protocols are vulnerable to attack, poor coverage and large interference

two。 High construction cost: need to build their own network and platform

three。 Operation and maintenance is difficult: single lamp positioning is difficult, troubleshooting needs to rely on manual, complaint or inspection maintenance.

NB-IoT-based solutions significantly address the above pain points

For the street lamp industry, what the owner requires is the annual lighting rate, while the operator is concerned about power consumption, so it is necessary to ensure both lighting and reasonable power saving. In addition to the technical improvement of the street lamp light source, the use of the street lamp also needs remote control and troubleshooting, so in the opinion of Changzhou Development APP Co., Ltd., at this stage, the intelligent transformation of the street lamp not only needs to report the cycle of the state of a single street lamp, but also needs to be able to carry out remote control, requiring the street lamp to have five remote functions: telemetry, remote signal, remote control, remote adjustment and remote viewing.

The intelligent street lamp scheme based on NB-IoT can realize the function of "five remote" of street lamp, including NB-IoT module, control module, power supply module and electric energy metering module. The power supply module supplies power to the LED lamp through AC electricity, and the NB-IoT communication module can communicate with the server, control and adjust the street lamp and report the data and information through the control module. At the same time, the electric energy metering module can calculate the lamp quantity of a single street lamp.

NB-IoT-based solutions have the following advantages:

one。 Convenient network: uniformly connect to the public network

two。 Unified standard: 3GPP standard, unified industry chain

three。 Safe and reliable: carrier-grade protection, communication success rate 99%

four。 Single lamp positioning: natural single lamp positioning, remote automatic control

five。 Preventive maintenance: big data type, operation and maintenance costs are reduced by 50%.

Based on the above scheme, the functions implemented in practical applications are as follows:

one。 Use time-sharing power control, such as more people and cars after sunset, 100% brightness; fewer people and cars at night, 50% brightness; after midnight, almost unmanned cars, 50% brightness, lights on at intervals

two。 Automatic adjustment combined with intelligent algorithm of longitude, latitude and sunshine time

three。 Single lamp fault detection and reporting to reduce maintenance costs.
