Railway Emergency Command System: Building an Uninterrupted On-Site Command Center

China's railway network spans thousands of miles and is a vital

part of the national transportation infrastructure. With the

continuous increase in line mileage and increasingly complex

operating environments, railway safety is facing unprecedented

challenges. How to quickly establish a stable and efficient on-site

command system in the event of accidents, extreme weather,

or communication limitations has become a critical issue in the

construction of the railway emergency management system.

Real-World Challenges of Railway On-Site Emergency

Communication

1. Railway lines often traverse complex terrain such as mountains, 

tunnels, and plateaus, where natural disasters such as heavy rain, 

landslides, snow, and strong winds are frequent. In the event of an

emergency, on-site communication is easily disrupted, and traditional

single communication methods cannot meet the requirements of 

"real-time, reliability, and collaboration" for emergency rescue.

2. During emergency response, the command center needs not 

only stable voice communication but also real-time access to critical 

information such as on-site video, personnel location, and

environmental data to achieve unified command and scientific

decision-making.

Core Ideas of the Railway Emergency Command System

1. The railway emergency command system is designed with

"rapid deployment, reliable communication, and information

integration" as its core principles. Through a portable emergency

command box, it highly integrates various communication

methods and sensing capabilities to build an on-site command

center in the shortest possible time.

2. Multi-mode communication integration ensures uninterrupted

command.

3. The system supports 450MHz walkie-talkie access, is compatible

with the existing railway communication system, and introduces

broadband wireless self-organizing network technology to quickly

build an on-site broadband network, achieving unified transmission

of voice, video, and data.

4. Through dual-mode operation of "narrowband cluster + broadband

network," it ensures reliable voice communication for command and

dispatch while meeting the needs of high-definition video transmission

and data sharing.

5. Multi-link redundancy design to cope with extreme scenarios.

6. To avoid communication interruptions caused by single-point failures,

the system has built a multi-link communication guarantee mechanism:

Satellite communication serves as an emergency backup when public

and private networks are interrupted.

Telecommunication operators' 4G/5G networks provide a regular data

channel.

Utilizing optical communication poles along the railway line, direct

connection to the dispatch center is achieved.

7. Multiple communication links operate in parallel and switch automatically,

ensuring "uninterrupted communication and online command" even in

complex environments.

8. Eliminating "Blind Spots" in On-Site Perception for More Precise

 Command and Control

Railway emergency command is not just about "hearing," but also about

"seeing clearly and maintaining control."

The system utilizes surveillance cameras and smart safety helmets to

achieve real-time transmission of high-definition video from the scene,

allowing commanders to grasp the accident situation immediately;

combined with personnel positioning and vital signs monitoring functions,

it provides real-time control over the distribution of rescue forces and their

operational safety status.

At the same time, the system can also access environmental monitoring

data such as weather and harmful gases, providing a scientific basis for

on-site decision-making and avoiding secondary risks.

9. Integrated Design for Improved Emergency Response Efficiency

The emergency command box adopts an integrated and portable design,

allowing for immediate use upon opening at the scene, enabling rapid

deployment. The system deeply integrates multiple emergency functions,

reducing the operational complexity caused by multiple devices and

systems running in parallel, and significantly improving on-site command

efficiency.

From daily inspections and handling of sudden malfunctions to emergency

rescue in natural disasters and major accidents, the railway emergency

command system can achieve full-scenario coverage, providing a solid

guarantee for safe railway operations.
