Project description
The integrated pipeline system consists of three parts: the monitoring center, communication transmission, and on-site inspection. The monitoring center is the core of the entire system. It links, coordinates, controls, and manages the work of various subsystems. The communication transmission layer consists of industrial switches and network transmission equipment. Composition, it is responsible for providing access to the data collected by the lower detection device and sending it to the monitoring center. At the same time, the instructions issued by the monitoring center are transmitted to each site node. The on-site inspection consists of web cameras, sensors, and PLCs. The PLC is responsible for the unified acquisition of detection signals in the corridors and the control of equipment in the corridors. In order to ensure the effective transmission of data, we use the Industrial Ethernet network and use the Mega industrial Ethernet switches form a gigabit fiber ring network to achieve Gigabit network transmission. Gigabit ring network can effectively guarantee the stability of data transmission. When a node in a pipe gallery fails, the entire network can quickly converge and recover.

Xiayu solution
A fire prevention zone is also called a functional zone for every 200m of the integrated pipe gallery. Each partition is isolated by a fire door. Usually, an I/O site monitoring room is set up between two partitions to serve as an integrated pipe network and others. An access point of the system is responsible for providing access to terminal equipment in the pipe corridors at both ends. A full Gigabit Ethernet switch is installed in the monitoring room of the I/O station to provide cameras, sensors, and alarms in the corridor. Equipment and other devices provide access. The ring network switches at each monitoring site use fiber to form a fiber ring network. In order to ensure the reliability of the pipe network, dual-fiber networking can be used. The optical port implements bandwidth superposition and link redundancy through link aggregation. The switch comes with the optical port Bypass function and the electrical port POE function. The Bypass function can realize the optical port through when the switch fails and ensure the link is unblocked. The POE power supply has an adjustable capacity of 24VDC/48VDC and can provide power to the AP or IP camera in the pipe gallery.The domain Ethernet industrial Ethernet switch is used as a supplemental access point for pipe corridors to meet different access environment applications.
