1. The KNTECH Tunnel Broadcast Communication System is a special tunnel broadcast system developed by Shenzhen Xijun Technology. It consists of SIP server, voice gateway, waterproof telephone terminal, power amplifier, IP66 waterproof speaker, network cable and other equipment.
2. This system can play background music, news, propaganda knowledge, etc. at various points in the tunnel, making it a tool to improve the production environment, strengthen information exchange, and improve spiritual and cultural construction.
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. Propaganda and broadcasting
This system can play background music, leadership speech, voice propaganda, etc. Can be based on
Specific requirements to broadcast different content, you can also record the broadcast content yourself.
3. Timed broadcast
According to production needs and related requirements, you can set up single or multiple broadcast tasks to be executed according to time, date, month, and quarter. When the specified time is reached, the system will automatically perform all specified tasks without manual operation and truly realize unattended operation.
4. 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.
5. 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.
6. 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 system.
7. 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.
8. Recording function
This system supports all calls to be formed into recording files, and the storage time can be set as required.
9. Remote monitoring function
The system dispatcher can monitor the sound around the speakers in real time as needed.
10. 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.
11. 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.
12. Online upgrade function
The system supports online upgrade, remote update and configuration, and it is convenient to upgrade the system and update the software.
13, power outage broadcast
Both the intrinsically safe speakers and the loudspeaker phones 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.
14. 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.
15. 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.
16. 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.
1. This system supports full-duplex voice intercom, each group of broadcasts can talk to each other, and the broadcast system can be connected to the mobile phone.
2. The dispatching station can call any main speaker, and the speakers in the tunnel can also call the dispatching station to directly establish a voice call.
3. The recording function of the system is extremely rich. It can record multiple channels at the same time, has independent playback channels, and can query recording, monitoring, playback, storage, etc. online in real time.
4. The dispatch station can remotely configure the parameters of special broadcast equipment in the tunnel, add and delete broadcast points, and control the broadcast system in an all-round way.
5. The system can set different priority and call authority for different users; it has emergency call function; it has the functions of forced interruption alarm function, emergency broadcast priority and other functions.
