Industrial Switch Helps Informatization of Rail Transit

At present, rail transit has been put into operation in Beijing, Shanghai, Guangzhou, Shenzhen, Hangzhou, Nanjing, Tianjin, Chongqing, Wuhan, Xi'an, Chengdu, Shenyang and other cities nationwide, and urban rail transit is in a period of vigorous development.

For the networked operation of rail transit, the industry has reached a consensus: If rail transit can not form a network, and the urban transport capacity cannot take a qualitative leap. In cities with relatively mature rail transit development, such as New York, London, Paris, Moscow and Tokyo, the rail transit system has basically formed a certain network scale and extended to all directions of the city. At the same time, these cities have achieved network operation, and the train operation technology has become mature.

The business opportunities of Industrial Switches in metro are mainly the metro PIS (passenger information) system, AFC (automatic fare collection) system and ISCS (integrated monitoring) system. At the same time, the metro vehicle network system also has a huge business opportunity of on-board industrial switches. For example, the industrial switch requirements of the AFC network system. Other systems are similar to the AFC network system, which are mainly divided into the central monitoring room, the subway dedicated communication channel, the monitoring center of each station and the information terminals on the station. For industrial switches, rail transit is a huge market.

Shenzhen Houshi Network Technology Co., Ltd., as a major market participant in key application networks, covers a complete range of data network signal transmission products, and industrial switch products cover rail transit, office communication, production automation, process control, and independent machine equipment control systems. Build a high bandwidth, flexible, redundant and safe backbone network through the industrial switch, and connect the rail transit core network to each subway line control center and road network command center; While ensuring network transmission with high reliability and low delay, different service types can be logically separated.

Solution features of our industrial switches in rail transit

Two on-board switches are deployed in each compartment to form a redundant two-layer ring network, and ERPS protection is configured with self-healing time<20ms

Industrial design, suitable for - 40 ℃~85 ℃

High reliability M12 air plug interface is adopted, with seismic design to ensure transmission stability in harsh environments

Support POE function

The whole network supports multicast IGMP Snooping V1/V2/V3 and GMRP

The whole network supports QoS, link aggregation, secure access, flow control, storm suppression and other functions.

Based on years of experience in the construction of operation solutions, we have basically realized the integration of control technology and communication information technology. Our industrial switch rail transit solution has the following four advantages: 1. The train dispatching system is global; 2. It is convenient to integrate the business system; 3. The video monitoring is networked; 4. The management, implementation and decision-making are global and efficient.

At present, our industrial switch products have been widely used in traffic automation, industrial automation and power automation. In the application of railway, light rail, subway, expressway, airport, wharf, metallurgy, paper making, automobile, wind power generation, water conservancy and hydropower, water supply and water treatment, petrochemical, pipeline and regional backbone network and other industrial key tasks and harsh environments, it is applicable to the requirements of strong electromagnetic interference, high ambient temperature, high mechanical load and rail clamping installation. In the future, we will make better use of industrial switches and information technology to support the overall network construction of rail transit and help the informatization development of rail transit!
