Smart streetlights:

1. Logical structure of smart city system

According to the construction requirements of smart cities, their logical architecture can be divided into IoT perception layer, transmission network layer, data platform layer, and business application layer.

The perception interaction layer is composed of front-end high-definition cameras, 5G small base stations, IoT gateways, environmental monitors, charging stations, display screens, broadcasting sound pillars, etc.

The network transmission layer adopts a "three network business integration" architecture, relying on the smart and bright communication network infrastructure to support the integration of high-level business applications. The network layer can achieve interconnection and seamless coverage; Interpenetration and intersection at the business level; The application layer tends to use unified network protocols; Capable of providing comprehensive multimedia communication services, including voice, data, images, etc., to achieve the aggregation and uploading of data collected by the perceptual interaction layer.

The data support layer mainly provides computing, communication, and storage services for the platform; The business application layer is located at the top of the intelligent visual city system, which concentrates the business applications of the city and realizes the business logic combination and data presentation of specific application solutions. The logical structure diagram is shown below:

2. System module structure

Smart street lights rely on smart light poles and LED street lights, integrating WIFI base stations, cameras, infrared sensors, radar, electronic display screens, charging stations, environmental monitoring sensors, etc., to become an information carrier, achieving data monitoring, environmental monitoring, vehicle monitoring, security monitoring, light pole screens, underground pipeline network monitoring, urban flood disaster warning, regional noise monitoring, etc A comprehensive smart city information management platform for citizen emergency alarm and other related information.

Mainly used for smart cities, smart technology parks, smart parks, smart streets, smart tourism, city squares, and bustling city streets.

The functional modules involved include: electronic display screen, intelligent lighting, charging station, mobile phone charging port, one click alarm, network broadcasting, 5G base station (model shell), environmental monitoring, video monitoring, street light gateway box, etc.

3. Intelligent street lighting energy-saving management

According to the architecture of the wireless control intelligent lighting control system, combined with the wireless application products developed by the company in various industries, various IoT and IT technologies such as wireless ZigBee, WIFI, GPRS, NB IoT, LoRa have been used to achieve remote single light switch, dimming, detection and other management functions, opening a new chapter in urban lighting "management and energy conservation".

This system integrates the lighting needs of street lights, tunnel lights, landscape lights, commercial lighting, school offices, hospitals, factories, stations, and airports, using a unified platform for management. It is an open system with various access methods reserved, which can further create a smart city "cloud" system platform. The overall system architecture is as follows:

The functional features include:

c) Through system control, it is possible to remotely switch and control any one, one, or customized set of street lights.

d) You can check the switch status, brightness, current, voltage, power, and other data of street lights at any time.

e) It can achieve fault alarm, fault detection, and fault handling status tracking functions.

4. Broadcasting sound system

a) Emergency calls can be made through the broadcast sound system.

b) Capable of conveying information in a timely manner, such as broadcasting background music, publishing information, broadcasting search for people, and fire broadcasting.

c) There are no limitations to operation, and it can also be set up through a local area network in places without an IP network.

5. One click alarm

a) Eight major environmental monitoring indicators: temperature, humidity, illumination, wind speed, wind direction, noise, PM2.5, PM10, to understand various monitoring indicators of the current environment.

b) Real time visibility of the on-site situation can be achieved through the installation of monitoring and perception devices on street light products, allowing for video monitoring and alarm of the monitoring area.

6. Environmental monitoring

a) You can call for emergency help with one click, providing better and safer information and protection for the people.

b) Convenient and timely provision of data to environmental protection departments, thereby helping them more effectively manage illegal emission enterprises and achieve the goal of jointly maintaining the environment.

7. Management and operation of new energy vehicle charging stations

a) Solve the problem of difficult charging of new energy vehicles in roadside parking spaces, parks, and residential areas.

b) The new APP online network coverage enables online convenient payment (WeChat, Alipay).

8. LED multimedia information release

a) Replacing traditional flagpole public welfare and commercial advertising, saving manpower and resources, making it convenient and efficient.

b) Real time remote control, publishing, management, and real-time updates.

c) Integrating sound, image, text, graphics, and video.

9. Video surveillance

a) Timely and accurately grasp the flow of vehicles and pedestrians around the monitored intersection and road section, as well as the traffic security situation.

b) Provide command personnel with quick and intuitive information to make accurate judgments and respond promptly to traffic accidents and congestion.

c) Video recording and evidence collection of sudden public security incidents within the monitoring scope, serving internal and external security work, and achieving a comprehensive governance effect.

10. Mobile phone charging port

a) Standard USB charging port provides convenient phone charging service.

b) Online convenient payment (WeChat, Alipay) is available.

11. Street Lamp Gateway
