This application discloses a highway tunnel system based on the open-source HarmonyOS. The system includes end-side components, edge-side components, and cloud-side components connected via communication. Each end-side component includes a controller and an adapter. The controller connects to the electromechanical equipment deployed in the highway tunnel and automatically networks with the adapter. The adapter also connects to the electromechanical equipment deployed in the highway tunnel. This application forms a "cloud-edge-end" topology through the end-side, edge-side, and cloud-side components, achieving centralized management and unified monitoring of the electromechanical equipment in the highway tunnel, reducing the workload and cost of manual inspections. Simultaneously, utilizing the distributed soft bus of the open-source HarmonyOS system enhances the communication efficiency and data interaction capabilities between the end-side, edge-side, and cloud-side components, improving the accuracy and timeliness of tunnel event detection and reducing false alarm rates. In the event of a fault, the end-side, edge-side, and cloud-side components can quickly coordinate and respond, reducing the time required for multi-department coordination, effectively shortening troubleshooting time, and improving operational efficiency.
