Application of Industrial Switch in Metro FAS System

In the subway FAS (Fire Alarm System) system, the Industrial Switch can play an important role, provide reliable and safe network connection, and support real-time data transmission and monitoring. The following is the application of Industrial Ethernet switch in FAS system of rail transit industry:

1. Equipment connection and data transmission: The metro FAS system usually includes multiple devices, such as fire alarm detectors, sound and light alarms, emergency broadcasting systems, etc. Industrial switches can provide multiple network ports for connecting these devices and data transmission through Ethernet cables. This can establish a unified network architecture, simplify device wiring and management.

2. Real time monitoring and control: The metro FAS system needs to monitor the status of various equipment in real time and provide corresponding control and response when a fire or other emergency situation is detected. Industrial switches provide high bandwidth and low latency data transmission capabilities, can support real-time monitoring and control requirements, and ensure that the system can respond in a timely manner and take appropriate measures.

3. Network security and redundancy: The reliability of the metro FAS system is crucial, especially in emergency situations. Industrial switches usually have network security functions, such as access control, data encryption and firewall, to protect the system from potential network attacks. In addition, some Industrial Ethernet switches also support redundant ring network protocol (RSTP) and other technologies to provide network redundancy and failover capabilities and enhance system reliability and fault tolerance.

4. Scalability and flexibility: The metro FAS system may need to be continuously expanded and upgraded to meet growing demands and new safety standards. Industrial switches have good scalability and flexibility, and can support various network topologies and device connection modes. This enables the subway FAS system to easily adapt to constantly changing requirements and facilitate system expansion and upgrading.

5. Network topology structure: The metro FAS system usually needs to design a distributed topology structure to improve the stability and reliability of the system. Industrial Ethernet switches can realize complex topological structures, including ring, star, tree and other network structures, to meet the needs of the subway FAS system.

To sum up, the Industrial switch plays a key role in the metro FAS system, providing reliable, safe and high-performance network connection and data transmission. They provide strong support for the operation and security of the metro FAS system by supporting equipment connection, real-time monitoring, network security and redundancy.

At present, as a large-scale infrastructure for urban construction, the subway is not only the backbone system of urban public transportation, but also the support system for urban construction and land development. The development of subway modernization has become one of the important symbols of urban transportation modernization. Through years of automation application experience, Houshi Network's Industrial switch products have been successfully applied in various fields, as well as FAS system in rail transit industry.
