Solution background
With the acceleration of urbanization, road lighting, as an important part of urban infrastructure, has become an inevitable trend in its intelligent transformation. Especially in our country, there are a huge number of lighting fixtures. If we still adopt the traditional management method, we will still face many challenges, such as high energy consumption, difficult maintenance, and single function. In addition, urban street lights are no longer just used for lighting, but have added more functions, such as environmental monitoring, security cameras, electronic billboards, charging piles, etc., and have become multi-functional carriers. In the process of street light management and function expansion, if the method of modifying the wiring is still used, the cost is high and the cycle is long, which cannot meet the development requirements. Shengrun Technology's ZigBee smart street lighting solution has shown great application potential in the field of smart street lighting due to its low power consumption, low cost, high reliability, and convenient networking, and has become an important force in promoting the development of smart cities.
Solution overview
This solution uses zigbee3.0 as the communication protocol of the solution. The hardware usesHY-2340 series modules. Terminal devices are deployed on street lamp poles and the data is uploaded to the cloud through the router coordinator. Environmental status can also be collected through sensors and then used by Zigbee. The terminal device is transmitted to the cloud, and then the status of each component can be controlled and set through the background. This includes adjusting light brightness according to environmental factors, playing different advertisements according to different times and environments, etc.
Solution features
1. Zigbee supports a variety of network topologies such as star, tree and mesh (Mesh), and can achieve stable communication between devices in complex urban environments.
2. The self-organization and self-healing capabilities of the ZigBee network enable it to automatically adapt to network changes and ensure the reliability and stability of data transmission.
3. This solution can automatically adjust lighting brightness and switching time according to road traffic flow, pedestrian density and ambient light. This precise control not only improves the comfort and safety of road lighting, but also significantly reduces energy consumption. Compared with traditional street lights, it can save more than 70% of energy, contributing to the sustainable development of cities.
4. Remote monitoring and convenient maintenance. Through the street light LAN composed of ZigBee, managers can remotely monitor the working status of each street light in real time, including voltage, current, brightness, fault information, etc., to achieve early warning and rapid location of faults. This remote monitoring method greatly reduces the workload of manual inspections, improves maintenance efficiency, and reduces maintenance costs.
5. Powerful communication capabilities: The transmit power of up to +8dBm and the receiving sensitivity of -96dBm ensure the module's wall penetration ability and meet the communication needs of complex urban environments.
6. Flexible communication methods: Supports dynamic switching of three communication methods: short address, long address, and data frame address to meet communication needs in different application scenarios.
7. Stable control function: With excellent radio frequency performance and stable control algorithm, it ensures the long-term stable operation of the smart street light system.
8. Easy maintenance. If one of the light poles fails, engineers can read the status information and fault information of the light pole on the ground, making maintenance more convenient and quick.
Solution implemented
With its excellent performance and wide application prospects, this solution has been approved and installed in many cities, setting a classic case in the industry. Judging from current feedback, the Zigbee smart street light solution is superior to traditional street lights in terms of energy saving, maintenance, and management.
