Hebei Expressway "Jihong" Smart Tunnel — China's First Fully OpenHarmony Expressway Scenario

Building the "Jihong OS" Digital Foundation for Connected Highway Electromechanical Systems with OpenHarmony

Project Background

Building a localized digital foundation: leveraging OpenHarmony to create "Jihong OS," the digital base for connected highway electromechanical systems, addressing issues such as device heterogeneity, information silos, and inefficient operations in traditional tunnels. The project was selected as a 2026 OpenHarmony Leading Commercial Practice Case. Through deep integration of "three hardware and three software" systems, 24 categories of electromechanical equipment in the tunnel — including fans, cameras, lighting systems, and CO/VI detectors — were upgraded with OpenHarmony.

Solution

Operations efficiency greatly improved: automated inspections replaced 80% of manual inspection workloads; device online rate increased from 56% to 95%; equipment replacement time shortened by 90%; and fault detection efficiency improved by approximately 60%. Maintenance cycles were reduced from an average of 3 days to 15 minutes.
Emergency response significantly accelerated: incident emergency response time improved from 5–10 minutes to 1–2 minutes, substantially reducing the risk of secondary accidents.
Cost control delivered notable results: annual tunnel maintenance costs decreased by 45%, and personnel required for single emergency responses reduced by 50%.
Highly recognized by the industry: winner of the Grand Prize of the Mao Yisheng Transportation Science and Technology Award, and successfully selected for Hebei Province's Major Science and Technology Support Program. In May 2026, it was named an OpenHarmony Leading Commercial Practice Case at the "Xinhuo Cup."
Demonstration and promotion value: the solution has been replicated and promoted in Jiangxi, Guangdong, Zhejiang, and other regions.

Customer Testimonial

This transformative advancement not only fully resolved information fragmentation between devices, but also significantly enhanced tunnel intelligence and safe operations, effectively reduced O&M costs, and comprehensively improved inspection efficiency and emergency response capabilities.
