By establishing a universal wireless air interface and its common standard protocol, different manufacturers' smart IoT devices can access the data of all IoT devices within a certain distance without the need for connecting wires or cables, and can access the smart road control platform.

6) Vehicle-Road Cooperation Function

The development of the Internet of Vehicles and autonomous driving technology provides high-precision positioning and refined information for vehicle-road cooperation technology, such as cloud computing, big data, and mobile internet technology, bringing significant development opportunities. The services and construction of the next-generation wireless sensor network provide a more reliable technical guarantee. As a new generation of intelligent transportation system, vehicle-road cooperation technology achieves all-round dynamic real-time information interaction between drivers and the road, completes the collection and integration of full-time dynamic traffic information, and achieves full information sharing. It actively controls road traffic, improving the efficiency of road network operation.

7) Environmental detection function

Using smart road lighting as a carrier, to rationally and effectively layout the city, forming a city perception network system that can timely, accurately, and comprehensively reflect the trend of environmental quality changes such as temperature, humidity, noise, PM2.5, current and developing PM10, CO2, etc., and provide a basis for environmental management, environmental planning, and environmental scientific research. It also provides timely and accurate information for the maintenance of basic service facilities in the city.

8) One-click alarm function

In case of emergencies or emergencies, citizens can press the one-click assistance button on the road intelligent pole to communicate with staff from the Public Security Bureau or rescue center, and at the same time, understand the location of the trapped person. Information is directly sent to the management platform, providing rapid and accurate information for public security or rescue personnel to arrive at the scene in a timely manner for corresponding handling and rescue.

Section 3: Technical Solution

Based on streetlight poles, integrating high-definition cameras, WIFI probes, guidance screens, signs, lighting, and other equipment, upgraded to intelligent road streetlights (streetlight poles, video poles, sign poles, guidance screen poles unified).

Protocol

Utilize common Internet of Things protocols such as Modbus, UDP/TCP, OCP, MQTT, HTTP, etc., to access all IoT devices that support these protocols.

Internet access method

The intelligent road lamp pole adopts a ring network. In response to connection failures, it is launched nationwide. The switches in the control cabinet and the core gateway in the intelligent road lamp are connected through fiber optic cables to form a ring network structure. Therefore, when using the main communication channel to transmit data, an auxiliary channel is added. In case of failure in the main channel, the channel used can be switched to improve the redundancy of the network system.

Project operation issues

Solution:

In terms of construction and operation models, the design of the EPCO (Engineering, Procurement, Construction, Operation) general contracting is the preferred model to ensure the professionalism and continuity of operation; or the leading department designated by the district committees serves as the main body for operation and maintenance, and entrusts professional companies to be responsible for operation and maintenance.

Project Features

1) Advantages:

Addressing the three core issues of current road intelligent construction:

a) Functional division leads to a large number of poles on both sides of the road (streetlight poles, video poles, guide screen poles, signboard poles, etc.), repeated excavation of the road, high construction and maintenance costs, and is a subject of many management disciplines;

b) There is a lack of unified pole deployment among departments, different data standards, difficult integration, leading to data fragmentation and difficulties in sharing;

c) Smart roads lack comprehensive planning and construction, lagging behind the intelligence of transportation vehicles, and are unable to meet the development needs of new technologies such as shared bicycles and road vehicle collaboration.

2) Innovation:

3) Experience for reference:

a) The technical solution is for reference, processing data on the front-end and uploading structured data to the backend to save network bandwidth.

b) The pole structure design is for reference, with interfaces reserved for the installation of 5G base stations, LTE-V, and other intelligent devices.
