Smart Streetlight Control in Smart Cities: Detailed Solution for 40% Energy Savings per Lamp via Industrial Cellular Router

1. Traditional Management Dilemma: High Energy Consumption & Inefficient O&M

In a second-tier city, 32,000 streetlights consume 94.5 million kWh annually, emitting 78,000 tons of CO₂. The traditional timer mode leads to >60%  midnight idle rates, while manual inspections take 2 weeks, with a 12-hour fault response time. This "extensive" management wastes energy and poses safety risks—a cable leak once caused 3 days of lighting failure, costing >¥2 million.
Key pain points:

• Energy: Uniform brightness control leads to 30%-50% excess energy use in low-traffic areas.
• O&M lag: Passive maintenance delays fault repairs, reducing reliability.
• Fragmented management: Isolated data limits smart city synergy.
