The Advantages of Our Industrial Switch Rail Transit Solution

Rail transit requires precise control of information in terms of time, speed, train intersection, etc., and requires extensive use of voice, video and other data transmission in scheduling, communication, real-time reporting, etc., which requires the establishment of reliable, easily scalable and independent communication network to transmit and process various information required for rail transit operations.

Industrial Switches have become an indispensable part of rail transit signal transmission systems due to their advantages of good openness, wide temperature operation, and strong anti-electromagnetic interference. Among them, the applications in subways are mainly PIS (Passenger Information) systems, AFC (Automatic Fare Collection) system and ISCS (Integrated Supervisory Control System) system. The application on high-speed railway is mainly in the new high-speed railway network and the transformation of traditional line network. In addition, it will also be used in railway signal control, train marshalling, railway power monitoring, railway AFC and other systems.

Demand for industrial switches in rail transit systems

High reliability and high availability requirements

Since the data network needs to provide 7×24 hours of uninterrupted service, the high availability and high reliability of the system is a very important goal, including considering the redundancy of network equipment and lines, such as VRRP, redundant ring network, etc. Failure time (MTBF>300000h), downtime cost, etc.;

Advanced requirements

The network equipment needs to adapt to the development characteristics of the rail transit system and the development trend of the network communication equipment. It needs to have a certain degree of advancement in host selection, network structure design, network equipment structure configuration, network management methods, etc.;

High performance requirements

The network structure adopts the multi-layer structure of access layer, aggregation layer and core layer, all Gigabit network;

Security requirements

Since the rail transit system involves the transmission of capital transaction data, it is necessary to consider ensuring network security and data monitoring and auditing;

Maintainability requirements

The system covers a large area, and all the field equipment is installed on the site with harsh environment. Partial failure of the system is inevitable, so the maintainability of the system must be considered in the design of the system.

Our industrial switch products are specially designed for rail transit and meet the requirements of EN50155 and EN50121 industry standards. The Ethernet port adopts M12 interface, which is firm and reliable, and is suitable for vehicle operating environment with severe vibration and impact. It has perfect management functions, which is convenient for visual management and online debugging. It greatly enhances the flexibility and security of the network through service authentication and anti-attack control. It adopts ring network redundancy technology and multi-link backup to ensure the stable and safe operation of the system.

Our Industrial Switch Rail Transit Solution:

The redundancy of the ring network is formed by three-layer optical fiber ring network switches to realize link backup to ensure the reliability of data transmission. The industrial switch adopts gigabit fiber ring, combined with the unique ring network technology, self-healing is less than 20ms, and the data is forwarded to the central server through the three-layer routing function, which can ensure the testability and security of network transmission. The access layer adopts managed layer 2 switch, which forward the card-swiping data of the gate to the platform server and the central server.

The advantages of our industrial switch rail transit solution:

1. Gigabit ring aggregation network, using high-performance private redundancy technology, when a link failure or single point failure occurs in the network, communication can be quickly restored within 20ms to ensure reliable data transmission;

2. Support virtual local area network isolation function to ensure the safe transmission of capital transaction data;

3. Fanless low-power design, support -40°C~+85°C, EMC4 level, IP40 protection level, guarantee 24-hour uninterrupted service in various environments;

4. The front-end equipment is plug-and-play, flexible and convenient, and it does not need to be replaced directly in the event of a fault, which is convenient for maintenance;

5. Enhanced network security

6. Support Layer 3 static routing, RIP V1/V2, OSPF, VRRP and other management functions

7. Ultra-high backplane bandwidth, large cache, wire-speed forwarding without packet loss

8. Industrial switch communication equipment supports SNMP, WEB browser, CLI command line, SSH, Telnet and other methods for centralized control and management, which is convenient for maintenance personnel to perform remote login, port mirroring, remote monitoring, status monitoring and other operations.
