EMU tail-catching vigilance

Silence, dead!

......

High-speed Railway Management uses wireless technology.

Specifically, the CTCS, GSM-R system, Railway Control Area Center-railway signal box-EMU-train control personnel, railway console personnel.

.......

Describes several concepts.

High-speed trains are railway routes, which are linear and gauge standardization.

A emu is a train on a railway. It is divided into five models based on the speed.

There will be one railway signal box for several railway lines, which is used to send signals for several railway lines with or without trains.

......

An accident is caused by lightning. a lightning strike causes a failure in the signal box.

We hope that similar accidents will not happen again. It is best to find out the root cause and eradicate the stubborn disease.

.....

Several Issues of vigilance are as follows:

1. Reference

There is an article titled:

Beijing-Tianjin Intercity Railway equipment: the most advanced communication signal system

 

How advanced and secure is this system?

Specifically, whether it can defend against network attacks will not cause traffic accidents.

2. Communication System of CTCs and GSM-R as the core of High-Speed Railway System

This picture is referenced and I am not fully aware of the EMU console from http://buy.703804.com/forum.php? MoD = viewthread & tid = 12585206 and latest. The control display in the middle should be the main display, showing all the content; there are several sub-displays on both sides, detailed display content. The following is the control lever, which is designed to be human and easy to operate.

After reading the indicator lights on the console, I have doubts... Why is there only three-color lights...

1) if there is no signal in the front railway signal box, the light should be on...

2) if the signal is affected by the weather and climate, and the signal similar to electronic warfare is messy, the light should be on...

3) CTCs, GSM-R communication protocol error correction ability, counterfeit identification ability, band and signal basic unit selection of anti-electronic interference ability ......

 

 

We hope that our experts will have preventive measures and a backup system in these aspects.

Suggestion: establish an early warning system between train and train. As long as the two trains are very close to each other and receive signals from each other, they will be warned that the first train will slow down and the first train will also slow down. Based on the characteristics of the wave, the attenuation wave x Bluetooth <x <radio can be selected after proper distance. (Positioning system ranging is also acceptable. In short, do not rely on the same underlying system for all systems. If a problem occurs in the underlying system, all systems will fail. For example, if the hardware signal of the Computer Interlocking System of the subway is faulty, the upper-layer systems of ATS, ATP, and OCC must make mistakes .) It is best to establish the interaction between the car and the car, rather than indirect a train-OCC-B train, signal scheduling from the end of the railway track to OCC, sometimes also errors. Just like talking to people, the key words are talking to people in person. One story, one story, one story, and one hundred stories may change.
