Tunnel construction is a multi-work, multi-task, multi-equipment coordination process. In order to ensure safe, orderly and efficient tunnel construction, it is necessary to require timely transmission of information between people, people and equipment, and equipment and equipment. ,accurate. In order to meet the increasing communication requirements of tunnels and related underground projects, real-time, comprehensive and accurate management of the construction site, and the necessary communication conditions for subsequent video surveillance, equipment management and safety supervision, basic network communication needs to be established. platform. The basic network communication platform utilizes the mature and stable communication technology, the international standard, and can realize linkage and multi-network integration with other digital systems. The basic network platform takes the fiber-optic cable network as the backbone, adopts the "switch + fiber" architecture mode, and provides a modular interface for the access of the precise positioning system, the wired telephone system, the gate access control system, the water pump monitoring system, and the video monitoring system. Thereby, centralized storage, management, analysis and manipulation of data of each business system are realized.
