Huawei’s Connected City Lighting Solution connects street lamps to the IoT and adopts a GIS-based management system, enabling cities to enhance the control and performance of every street lamp. The solution provides municipal managers with status information on each lamp on any given street and enables precise control of on/off switches and the brightness of individual lamps, allowing on-demand lighting and up to 80% reduction in energy consumption.
There are currently 304 million street lights in the world, with this number expected to grow to 352 million by 2025. While street lighting has become an important symbol of modern life, city administrators are increasingly challenged to manage the vast service costs and environmental impact of inefficient street lamps.
Huawei has launched an innovative Connected City Lighting Solution that integrates leading new ICT. The solution introduces RF Mesh network into a smart sensor network featuring automatic discovery, self-networking, speedy self-healing, and device plug-and-play. The network deploys high-speed LTE, 3G, or GPRS agile IoT gateways as a remote communications bridge, and open, smart agile controllers as the core control components to interoperate with differentiated lighting control systems. In this way, the solution builds a reliable, open connected lighting network to implement multi-level smart control and visualized management.
- Integrated Smart Lighting Policies to Ensure High Energy Efficiency
With Huawei’s Connected City Lighting Solution, each street lamp is equipped with a power and brightness controller. To enhance the control and performance of street lamps, the solution integrates a series of preset smart lighting policies to:
- Automatically calculate lighting duration based on local longitude and latitude, and dynamically adjust lighting duration according to the specific season, month, and day
- Smartly adjust brightness by connecting built-in brightness sensors with third-party traffic and people flow sensors, or based on weather and other environment conditions. For instance, automatically reduce street lamp brightness or only switch on every other lamp at midnight when traffic volume is low; or turn lamps on when there is poor visibility such as on rainy days
Huawei’s Connected City Lighting Solution pairs LED lamps with smart lighting polices. When compared with conventional street lamps, such as high pressure sodium lamps, they help reduce energy consumption by up to 80%.
- Visible Management and Online Inspection to Prevent Failures
Huawei’s solution adopts a GIS-based management system, which displays comprehensive information about the street lamps, including the number of lamps in each street, their current status, as well as their installation position and time. Using this solution, one person can manage thousands of lamps in different streets. Additionally, the solution provides full lifecycle management to prevent potential malfunctions. When a street lamp does malfunction, the system is automatically alerted and sends a message to notify maintenance personnel.
- Multi-level Smart Control to Enhance Protection and Reliability
Huawei’s Connected City Lighting Solution provides multi-level smart controls, which are comprised of network smart controls on the first level and local smart controls on a secondary level. The agile IoT gateways and street lamp controllers are equipped with lightweight components to execute lighting policies and deliver a two-level localized decision-making mechanism. When the uplink network of agile gateways fails, local control protocols are enforced. Therefore, if the RF Mesh network fails, street lamp controllers can work offline and function independently. Multi-level smart control minimizes the lamps’ dependency of centralized controls, thereby increasing flexibility and reliability.
- All-layer Openness to Build a Smart City
In addition, Huawei’s Connected City Lighting Solution runs on an open architecture to seamlessly interoperate with smart terminals and municipal applications, including environmental monitoring, intelligent transport, and urban governance. Such unified management and a data service platform provide city administrators with an immense amount of first-hand data about city operations, laying a solid foundation for smart cities.
