Energy constraints are making it more difficult to meet development requirements of the global economy. City lighting is a part of city infrastructure construction that directly affects people's lives. Traditional lamps with high power consumption (such as high-voltage sodium lamps) are widely used, and energy is wasted due to improper management. Huawei Connected City Lighting Solution provides unified management of street lamps in different areas and implements real-time, refined switch-on and switch-off control, and brightness adjustment, implementing on-demand lighting. This solution minimizes the power consumption of street lamps while ensuring lighting quality. Additionally, this solution allows customers to obtain the running status of street lamps, measure power consumption of street lamps, and promptly detect device faults, reducing maintenance costs.
The test bed aims to build a showcase of lighting IoT predictive maintenance for the industry, obtain industry recognition, and implement incubation of this solution to lay a foundation for subsequent large-scale replications. In addition, street lamps are important elements in urban IoT. Lamp posts act as access nodes for the wireless network and connect to neighboring devices such as trash can detectors and parking sensors, building the scalable city IoT framework and facilitating the evolution of lighting IoT to city IoT.
The test bed uses advanced sensing, network, computing, control, and intelligence technologies to fully detect lighting devices, remotely implement real-time and periodic control of street lamps, and achieve self-diagnosis and predictive maintenance.
The test bed remotely and intelligently controls and maintains street lamps, detects the final status of the system, measures and analyzes the power consumption of street lamps in real time, and diagnoses faults of street lamps or the lighting system to realize predictive maintenance. It has the following effects:
What benefits does it bring to customers?
1. The system can ensure normal operation of street lamps in adverse weather conditions.
2. The system can calculate the sunrise and sunset times based on the longitude and latitude of each street lamp. This ensures that street lamps are powered on immediately after sunset and then powered off immediately after sunrise.
What benefits does it bring to municipal governments?
1. Street lamp controllers comply with industry standards. They can be used remotely, are compatible with a wide range of street lamps, and have zero installation costs.
2. Upper-layer applications can detect the real-time status and data of lower-layer devices, report device faults, collect statistics on and analyze the service life of street lamps, and implement visualized management based on the GIS, reducing maintenance and management costs for street lamps.
3. The test bed collects information on exceptions and faults to provide self-diagnosis and analysis. The test bed is able to provide services for users remotely and solve simple problems to reduce the number of onsite services.
4. Gateways and street lamp controllers support multi-level offline control. When uplink and downlink network faults occur, routine scheduled tasks can still be executed properly. The test bed ensures reliable running of the system and that faults do not affect the daily lives of citizens.
5. The test bed controls and adjusts the brightness based on the environment. This prevents energy wastage, improves lighting security, and reduces power consumption of street lighting.
6. The test bed remotely obtains and analyzes power consumption data of city lighting, laying the foundation for energy management of the municipal government.
According to the statistics report by the International Energy Agency (IEA) in 2014, around 20900 TWh electricity is consumed globally. Assuming that street lamps consume 6% of the total electricity, the electricity consumption of street lamps is over 1250 TWh globally. Typically, a high-voltage sodium lamp consumes 400 W power and costs over CNY 1500 per year, which is much higher than the cost of the lamp itself. Energy saving on street lamps has lucrative economic benefits and can promote growth in the market. According to statistics, the lighting IoT provides lower energy consumption (up to 40% secondary energy saving) and lower maintenance cost (maintenance labor cost reduced by 90%). The potential of this market is immeasurable.
The social benefits of the lighting IoT are simple. By reducing power consumption, the lighting IoT can reduce greenhouse gas emissions, save energy, and protect the atmosphere.
