Application of industrial switches in rail transit vehicle-mounted systems

As we all know, almost every city has industrial and rail transit, and industrial switches are indispensable in rail transit. Do you know the application of industrial switches in rail vehicle systems?

The rail transit PIS system is a system that relies on multimedia network technology, takes computer systems as the core, and uses stations and on-board display terminals as media to provide information services to passengers. Under normal circumstances, the PIS system provides passengers with information on boarding, first and last train service time, train arrival time, train timetable, manager announcements and other operational information and public media such as government announcements, media news, live events, advertisements, etc. Coordination and use of information; In emergency situations, based on the principle of priority use of operational information, dynamic auxiliary prompts can be provided, so that passengers can use the correct service information to guide passengers safely and conveniently on rail transit.

Use Ethernet to collect and transmit monitoring data and video signals to improve network security and ensure the reliability of system networking; The data is transmitted to the control centers in a timely and error-free manner. Due to the harsh environment at the use site, there are very high requirements on the material and performance of the product. It is not only necessary to limit vibration, jitter, wide temperature, humidity, and power supply system standards, but also to avoid the degradation of communication quality caused by electromagnetic interference.

JHA-IF26-1 副本

The JHA-IF26  provides 6 10/100M ring network 100M electrical ports and 2 100M SC optical ports. It is used to transmit video, audio and other data through a single network. In addition, a self-healing ring network can be formed. The switch self-healing ring high-performance redundancy technology is adopted. When a failure occurs in the train network, the communication can be quickly restored within 20ms to ensure The network operation is reliable and stable. Avoid data transmission loss when a single network is interrupted, and improve the reliability of network communication.

The above is an introduction to the application of industrial switches in the track. I hope it will be helpful to everyone. I also hope that through the above knowledge, everyone can understand industrial switches more clearly.
