Communication Solution fr Utility Tunnel

The utility tunnel, also known as the urban underground utility corridor, is an integrated underground passageway that houses multiple types of infrastructure, including electricity, telecommunications, gas, heating, water supply, and drainage pipelines. As a modern, scientific, and centralized urban infrastructure, it effectively resolves issues such as “spiderweb-like overhead cables” and “frequent road excavations.” Designed with dedicated access points for maintenance and featuring unified planning, construction, and management, the utility tunnel serves as a critical “lifeline” to ensure the smooth operation of urban systems.

However, the underground utility tunnel presents a highly complex and relatively enclosed environment, placing stringent requirements on the reliability, stability, and functionality of its communication systems. A robust and fully integrated communication solution not only enables real-time communication between personnel inside the tunnel but also ensures the timely transmission of equipment operation data and safety information. This plays a vital role in maintaining the safety and operational stability of the entire corridor network.

The utility tunnel contains a wide range of complex pipelines and extends over long distances, making data transmission within such environments susceptible to loss or interference. Leveraging years of expertise in developing and manufacturing industrial telephones for utility tunnels, highways, railways, mining, oil & gas, petrochemical, metallurgy, and power industries worldwide, Shenzhen Yuantong has designed a dedicated fixed communication system for utility tunnels. This system features a hybrid fiber-optic and cable network architecture specifically tailored for the challenging conditions of underground corridors.

The system integrates multiple advanced functions, including fiber-optic transmission, hybrid networking, soft switching, management and dispatching, digital recording, call positioning, and public address broadcasting. It enables real-time collection, transmission, and processing of information, and supports intelligent decision-making and command systems to improve operational efficiency. This provides a reliable communication backbone for the safe, efficient, and sustainable operation of utility tunnels while ensuring robust management and maintenance capabilities.

Moreover, the system offers diverse structural configurations, flexible networking options, and strong compatibility. Depending on the specific conditions of the utility tunnel, users can choose between fiber-optic networking or hybrid fiber-cable networking to achieve seamless data link transmission. The system also supports scalable expansions and customized configurations to meet varying operational needs.
