The automation monitoring solution for Runlin Tunnel (comprehensive pipe gallery) deeply integrates cutting-edge technologies such as Internet of Things, wireless communication, and cloud computing to build a 24-hour, all-weather, and multi-dimensional online monitoring system for tunnel engineering.
During the tunnel construction phase and operation cycle, monitoring work is a key link in ensuring the safety of engineering construction, controlling engineering quality, ensuring the normal operation of the ground transportation system, the stability of surrounding building structures, and the safe operation of underground pipelines. This solution adopts advanced automation monitoring technology, using high-precision sensors to perform real-time and dynamic monitoring of the main structure and lining structure of the tunnel. By continuously collecting key data such as displacement, stress-strain, etc. of the structure, accurate insights into the changing trends and stress states of the structure can be obtained, enabling timely detection and warning of potential safety hazards.
At the technical implementation level, IoT technology builds a data exchange bridge between devices, ensuring high-speed and stable transmission of various sensor data; Wireless communication technology breaks spatial limitations and ensures real-time and accurate feedback of monitoring data to the monitoring center; Cloud computing technology provides powerful data storage and analysis capabilities, deeply mining and processing massive monitoring data, providing solid data support for safety management decisions during tunnel construction and operation, and comprehensively safeguarding the safety and stability of the entire lifecycle of tunnel engineering.
