At the end of 2020, EXC’s smart street lights were installed in Longhua County, Chengde, with nearly 1,000 Zijing and Qingtian series smart street lights strategically placed throughout the area. The coverage includes the Dongshan Tunnel, West Ring Road, the highway connection line, and park routes, evenly distributed along the city’s main roads. These smart street lights from EXC have improved management efficiency by 70% and achieved 60% energy savings. The one-stop management center, powered by the Smart Cloud Control Platform, provides visualized city management, enhancing efficiency and reducing costs. This discreetly initiated a “domination” mode, with all major roads being efficiently managed, marking a new chapter in the smart operation and maintenance of Longhua County.
