Tunnel Emergency Telephones: IP Emergency Telephones Enhance Tunnel Safety and Emergency Communication

In enclosed spaces such as highway tunnels and urban

underground tunnels, establishing reliable communication

quickly is crucial in the event of an accident. Tunnel

emergency telephones, as an important component of

the tunnel safety system, play a key role in enabling

people to request help and contact the command center.

IP-based emergency telephones, utilizing a networked

architecture, are becoming the mainstream choice for

modern tunnel emergency communication systems.

I. What are Tunnel Emergency Telephones?

Tunnel emergency telephones are emergency

communication devices specifically designed for tunnel

environments. They are usually installed on the tunnel

sidewalls, emergency parking areas, or evacuation

passages. When a vehicle breaks down, an accident

occurs, or people are in danger, drivers and passengers

can quickly contact the monitoring center by simply

pressing a button.

Compared to traditional analog telephones, IP emergency

telephones transmit voice signals over an IP network,

offering advantages such as flexible deployment,

centralized management, and stable communication.

II. Core Functional Advantages of IP Emergency

Telephones

In tunnel applications, IP tunnel emergency telephones

offer several key functions:

One-touch emergency call: No dialing required, lowering

the barrier to use.

Direct connection to the tunnel monitoring center: Ensuring

timely and accurate information transmission.

7x24 hour stable operation: Meeting the tunnel's round-the-clock

safety needs.

Networked centralized management: Facilitating operation and

maintenance and status monitoring.

Through the IP network architecture, tunnel emergency telephones

can be quickly integrated into the overall intelligent transportation

system.

III. Humanized Design to Improve Emergency Assistance Efficiency

In actual use, people in tunnels are often in stressful or low-light

environments, so the appearance and interactive design of the

equipment are particularly important:

Clearly marked "Press this button to talk" operating instructions.

Bilingual prompts "PRESS THE BUTTON FOR HELP," suitable

for diverse user groups.

The emergency call button is prominently displayed for quick

identification.

This intuitive design significantly improves the success rate

of using tunnel emergency telephones in real emergency

scenarios.

IV. Integration of IP Emergency Telephones with Tunnel

Systems

IP emergency telephones can be linked with tunnel PLC

area control cabinets, serving as important front-end

terminals for the tunnel's integrated management platform. 

They work in conjunction with broadcasting, video

surveillance, lighting, fire protection, and other systems to

build a complete tunnel emergency communication network.

Through centralized control and intelligent linkage, the

efficiency of tunnel emergency response and overall safety

management are improved. V. Installation Method and

Application Scenarios

The IP-based tunnel emergency telephone adopts a

wall-mounted installation method and features a compact

structure, making it suitable for multi-point deployment

inside tunnels. It is widely used in:

Highway tunnels

Urban underground tunnels

Urban expressways and integrated transportation corridors

Whether for new projects or renovation projects, the IP

emergency telephone can be flexibly integrated into

existing networks.
