KXT23 Mine-used System for Broadcasting and Intercom based on IP Network has functions of network broadcasting, amplifying intercom and so on.
In normal circumstances, the system can be used as a tool for improving production condition, enhancing information communication and intensifying spiritual and cultural construction by playing background music, news, propaganda and report, etc. in mine underground.
In emergency circumstances and evacuation, dispatcher on surface can use the system to send command, guide evacuation by broadcasting, ensuring personnel on site escape from dangerous area rapidly, orderly and safely. Personnel on site also can use any terminal in mine underground to communicate and intercom and to report the site condition, thus greatly reducing disaster effect and secondary effect in rescue process after disaster. |

Function of setting and downloading played contents: the system can download contents (including music, sweet wishes, ringtones for work, and news) and set up play time, order and volume for individual or all terminals on audio server; |
|
Function of auto play: the system can automatically play or stop playing listings stored on terminals according to the playlist preset on audio server; |
|
Function of realtime play: the system can send audio file which is needed to be played urgently to terminal through network and play it immediately; |
|
Function of communication between user terminal and dispatcher: user can talk with dispatcher in control center by pressing ¡°Dispatch¡± key at any condition of the terminal; |
|
Function of communication between terminals: user can talk with other terminal users or broadcast to all by pressing ¡°Select¡± key; |
|
Function of emergent broadcasting: dispatcher can make emergent broadcasting to any individual user, users in any area or all users at any condition with high priority; |
|
Function of monitoring: dispatcher can monitor sound around any terminal; |
|
Function of sound recording: the system can record dispatcher¡¯s talk to terminal user into file for tracking it; |
|
Function of regular checking: the system sends command to terminals and interfaces at scheduled time for synchronizing time with them and for finding out their communication status in realtime. If any optic-fiber cable breaks or terminal fails, the system can display immediately; |
|
Function of extended connection: since severe environment (such as workface in mine underground) is not suitable for extending optic-fiber cable, the system is equiped with interfaces to connect with main machine or extensions of KXT22 Device by 4-cores cable (generally 1 mm  communication cable can work with 3 sets of main machine or extension in 2 km), thus realizing broadcasting intercom. |

|
System Capacity: unlimited for terminals and interfaces if the bandwidth permitted |
|
Maximum Transmission Distance: optic-fiber transmission  20 km |
