The new smart city is a complex and huge project, because of the complex system, a wide variety of peripherals, and are modular installation, with a variety of applications. Smart transportation, smart municipal, smart scenic spot, smart security, etc., are typical smart street lamp pole application scenarios. Parks, squares, scenic spots, pedestrian streets, and urban roads can all be display places for different configurations of smart street light poles.

As far as the practical application of the current smart light pole is concerned, there are inevitably two situations, one is the intelligent transformation of the stock light pole, the other is the new smart light pole, if it is the new light pole, it is necessary to consider the geographical location of the city where the light pole itself is located, whether it is the living area of the cultural and educational area or the main road of the city, or other characteristic places, if it is the old light pole transformation, In addition to considering the above geographical location, it is also necessary to consider the weight bearing capacity of the existing light poles and the ease and cost of renovation. Below, I will communicate with you about the design scheme of the intelligent lamppost system.

First, the system composition of the intelligent road light pole

The intelligent light pole system architecture is composed of four layers: device perception layer, network communication layer, data aggregation layer and platform application layer.

1. The device perception layer refers to the sensing equipment and technology such as cameras and sensors, which can realize the comprehensive perception of all terminal devices in the smart light pole solution. The intelligent street light pole involves the sensing layer equipment, including: intelligent street lights, security cameras, LED displays, environmental monitoring related sensors, etc.

2. Through the network communication layer, the device awareness layer can report relevant information to the data layer, and can also receive the corresponding operation instructions and execute them. In the smart light pole solution, flexible networking is used to control and monitor street lights, while 4G, wired and other communication solutions are used to support seamless access of various sensor devices, which is convenient for unified data collection and management analysis, which is also the top priority for network security, equipped with SVIP-3A28 network intrusion monitoring device and protection security monitoring system. It can effectively prevent hackers from tampering with the display of the terminal equipment on the smart street light pole.

3. Above the network communication layer is the data convergence layer, which will perceive the original data information obtained by the layer, such as temperature, humidity, noise, surveillance video, etc., here also provides multi-layer data fusion processing. The application layer functions include street lighting monitoring, security monitoring, environmental monitoring, information release, network broadcasting, emergency call, LED screen, charging pile, IP sound pillar and other functions.

4. Platform application layer, which provides operation and maintenance services for managers, supports platform applications on PC and mobile phones, and can also be combined with digital twin system to better serve managers.

Second, the system design idea of intelligent road light pole

1, the system is based on the integrated management platform of Kicchen smart street lamp pole, to achieve the point (smart street lamp pole), line (road), surface (city) three-level monitoring, to achieve light control, screen control, video surveillance, data acquisition, linkage unity.

2, a city's smart road light pole system, according to the region, power supply lines, roads, etc., composed of a number of sub-stations.

3, each sub-station, usually composed of intelligent lighting distribution box and a number of smart lampposts, intelligent lighting distribution box in the centralized controller (RTU) equipment to collect data on the lampposts for centralized processing, under normal circumstances, an intelligent lighting distribution box control 4 circuits, about 200 street lights control.

4, each smart street light pole is composed of intelligent box equipment and single light controller, on this basis, you can choose to install cameras, smart sensors, WIFI hotspots, LED information screen, one-button call alarm, charging pile and other equipment. At the same time, the road around the main light can be equipped with intelligent parking locks, which are centrally controlled by the main light master.

5. Optical fiber needs to be laid at the light pole of the smart road, and the intelligent box device is centrally accessed through optical fiber; For new street light systems, it is recommended to use power composite cables (including power cable core and optical fiber cable core), while completing the laying of power lines and optical fibers. In some remote areas, where optical fiber access is difficult, the device can be centrally accessed through the 3G/4G network of the mobile operator.

6, the smart box device can access a variety of devices, centralized data processing, using a unified protocol and platform for docking.

7. Each smart light pole is only equipped with a single light control unit, which sends the collected real-time status information (voltage, current, power, etc.) and abnormal alarm information to the cloud platform through wireless means for centralized processing. At the same time, the single lamp control unit accepts the control command through wireless mode, and realizes the functions of turning on and off the lamp, brightness adjustment, chrominance adjustment, etc.

8, for some remote areas, the power supply of street lights is difficult, you can use solar energy, wind power for self-supply.

9, if the street lamp renovation project is involved, it still uses traditional high-pressure sodium lamps, then each lamp needs to install additional electronic ballast.

Third, the design principles of the intelligent road light pole system

The design of intelligent lamppost follows the principle of advanced technology, complete functions, stable performance and cost saving. And comprehensive consideration of construction, maintenance and operation factors, and will leave room for future development, expansion, renovation and other factors to expand. The design content of the intelligent lamppost system is systematic, complete and comprehensive; The design scheme is scientific, rational and operable. It has the following principles:

1. Advanced nature and adaptability

The system integrates many advanced technologies in the world, embodies the latest development level of current computer control technology and computer network technology, and ADAPTS to the requirements of the development of The Times. At the same time, the system is used for various management levels. Its functions and configurations are designed to provide comfort to the user. Safety, convenience and speed are the criteria, and its operation should be simple and easy to learn.

2. Economy and practicality

Fully consider the actual needs of users and the development trend of information technology, according to the user site environment, design the selection of functions and suitable for the site situation, in line with user requirements of the system configuration scheme, through strict and organic combination, to achieve the best performance-to-price ratio, in order to save project investment, while ensuring the needs of the implementation of system functions, economical and applicable.

3. Reliability and safety

The design of the intelligent lamppost system has high reliability, which can ensure the accuracy, integrity and consistency of the data after the interruption caused by the system failure or accident, and has the function of rapid recovery. At the same time, the system has a complete set of system management strategies, which can ensure the operation safety of the system.

4. Scalability

The design of the intelligent lamppost system takes into account the needs of future technology development and use, and has the possibility of updating, expanding and upgrading.
