1. The Joiwo Tunnel Broadcast Communication System is a special tunnel broadcast system developed by Joiwo Explosion proof Science and Technology. It consists of SIP server, voice gateway, waterproof telephone terminal, power amplifier, IP66 waterproof speaker, network cable and other equipment.
2. When an emergency occurs and an emergency evacuation is required, the ground dispatching commander can use this tunnel emergency telephone system to send instructions to the scene by means of amplifying and calling, and direct the scene personnel to evacuate the dangerous area quickly, orderly and safely. On-site personnel can also use any terminal in the tunnel to shout and talk on the spot, and report the situation on the spot, thereby minimizing the impact of the disaster and the secondary impact in the post-disaster rescue process.
Emergency telephone system for tunnel
System functions:
1. Emergency broadcast
Broadcasting can be inserted at any time at any state and at any time, and emergency broadcasts can be made to a single area, multiple areas and all areas as needed, and relevant instructions can be issued at the first time to improve production efficiency and rescue efficiency.
2. Full-duplex voice intercom
In the event of an emergency, the system can directly call the relevant personnel and directly talk to the people in the tunnel by voice intercom, which is convenient for work contact.
3. Online fault diagnosis
The working status of all main and auxiliary speakers can be viewed remotely. Once the communication cable is interrupted or the intrinsically safe speaker fails, it can automatically prompt the fault location and other information, which is convenient for maintenance.
4. Self-organizing system
Intrinsically safe speakers are interconnected by dedicated network cables or dedicated optical cables, and a full-duplex communication system can be formed without a dispatcher. In addition, half-duplex conversations can also be conducted between amplifier phones connected to intrinsically safe speakers to form a local communication telephone system.
5. Linkage with safety monitoring system
The system can be connected to the alarm signal generated by the safety monitoring system (such as gas overrun, water penetration, etc.), and the alarm signal will be sent out in the first time.
6. Recording function
This system supports all calls to be formed into recording files, and the storage time can be set as required.
7. Volume adjustment
The system can remotely adjust the call volume and playback volume of the main and sub speakers to achieve a satisfactory call effect.
8. Real-time voice broadcast
The system can collect other audio sources as needed and forward them to the designated receiving area at the same time. The source can be any audio file or device.
9. Online upgrade function
The system supports online upgrade, remote update and configuration, and it is convenient to upgrade the system and update the software.
10, power outage broadcast
Both the intrinsically safe speakers and the loudspeaker telephones in the system can be equipped with a backup power supply, which can ensure that the system works normally for no less than two hours in the event of a power failure.
11. Docking various communication systems
The networking is flexible, and it can be connected to the existing communication dispatcher to realize seamless communication between the telephone and the speaker; a variety of communication systems can be accessed.
12. Easy to install
The main and auxiliary speakers are all intrinsically safe, developed according to the characteristics of the tunnel, and can be installed in working faces, tunneling faces and other places.
13. Dual machine hot backup
This system supports dual-system hot backup. When an abnormality occurs in the system, the backup system can be quickly switched to prevent data loss or control out of control and ensure the reliability of the system.
As technology continues to advance, efforts are being made to further enhance tunnel emergency telephone communication systems. Future developments could include integrating artificial intelligence algorithms to analyze emergency call data and improve response strategies. In addition, advances in wireless communication technology may eliminate the need for physical telephony units, allowing users to connect via smartphones or other portable devices.
To sum up, the tunnel emergency telephone communication system plays a vital role in ensuring the safety and efficiency of tunnel operations. These systems enable rapid response and effective coordination by providing instant and reliable SOS telephone communications in emergency situations. As tunnels remain an integral part of our infrastructure, implementing such communication systems is critical to the well-being of tunnel users and overall public safety.
