Application Analysis of Industrial Switches in Smart Rail Transit

As the saying goes, in urban construction, transportation comes first. Rail transit is the golden key to solving the "urban disease", and smart transportation is an important component of building smart cities.

Since 2009, China has gradually entered the peak of urban rail transit construction and expanded the subway market year by year. Developing a public transportation system primarily based on rail transit is an effective means of alleviating traffic congestion in various regions at present. Rail transit requires precise control of information such as time, speed, and train intersections, and requires extensive use of voice, video, and other data transmission in scheduling, communication, and real-time reporting. This requires the establishment of a reliable, easily expandable, and independent communication network to transmit and process various information required for rail transit operation.

Industrial switches have become an essential part of rail transit signal transmission systems due to their good openness, wide temperature operation, and strong resistance to electromagnetic interference. They are mainly used in passenger information systems, automatic ticketing systems, and subway platform screen door systems.

1. Passenger Information System

The passenger information system is a service system in the subway that provides information to passengers. It relies on multimedia network technology, with computers as the core and station and onboard displays as the media to provide information services to passengers, including but not limited to audio broadcasting platforms, alarm platforms, and video monitoring. All real-time playback media must not have sound pauses, mosaics, or other conditions, so the reliability requirements for the network and transmission system are high.

2. Automatic ticketing system

The automatic ticketing system is an automated system based on computer, communication, network, and automatic control technologies, which realizes the processes of ticket sales, ticketing, billing, clearing, and management in rail transit. Due to the fact that the system carries financial data for rail transit and is linked to multiple systems such as bus cards, its stability and safety reliability are of utmost importance.

3. Subway platform screen door system

The information transmission between central level management and station level management adopts the 100/1000/10000M TCP/IP channel provided by the communication profession, and the terminal equipment is connected through a bus. Set up a central management workstation in the control center, and set up a central authorization workstation with desktop card readers in both the control center and the vehicle depot to authorize and manage access levels, passwords, special permissions, and other functions for door access cards. Each station is equipped with workstations to monitor the terminal equipment of the station access control system.
