● Dispatching function:
Realize the integration of wired/wireless scheduling, and support the forced insertion, forced dismantling, group calling, monitoring, and recording of broadcast terminals.
Dispatch broadcast: The dispatcher can select a group on the dispatch console and execute the "broadcast" operation. All members of the group will receive a broadcast call, and the terminal that receives the broadcast call will automatically answer the call and answer the broadcast content. This operation can only be initiated by the dispatch console. You can voice broadcast or play prerecorded voice files to broadcast calls.
Trigger broadcast: The dispatcher establishes a temporary group and sets the broadcast trigger number for that group. All members in the group can dial the trigger number to initiate a broadcast call.
Broadcast amplification: The dispatcher calls the user of the broadcasting station, and the broadcasting user calls the broadcasting user. The broadcasting station can choose to have 1 to 3 rings without answering the automatic amplification speech, and the amplification loudness can reach 110 dB.
Broadcasting mutual dialing: The broadcasting station has a dialing keyboard and an emergency dialing key. Users of the broadcasting station can dial for scheduling or call each other, and emergency situations can be called for scheduling.
Scheduled broadcast: Multiple playback plans can be added, supporting when to play, controllable playback duration, and controllable playback sequence.
Zone broadcasting: Broadcasting can be divided by region and calls or music can be played in different regions.
Map broadcasting: It is possible to initiate broadcasting calls on all members (circled) within a certain area on the GIS interface.
TTS text broadcasting: Professional TTS voice conversion design that directly inputs text or automatically converts edited text files to voice broadcasting through the broadcasting system.
Gas linkage broadcasting: It is connected to the mine gas monitoring system. When the gas concentration exceeds the standard, the broadcasting system automatically sends a voice notification to the designated personnel and the site after receiving instructions. (Mining Applications)
*Video linkage broadcasting: Supports real-time video analysis of whether there are belt deviations, belt stacking, belt underspeed, and other situations. In case of abnormal situations, the system automatically sends broadcasting notifications to the intelligent terminals of the duty personnel and on-site duty personnel. Note: Intelligent video analysis in other industries can be customized and developed.
● Fusion function
Communication integration: The software and modules developed by our company fully support the SIP protocol and can be well integrated with the dispatching system. The landline can dial the audio module for broadcasting and fixed-point two-way intercom, and the terminal module can also call fixed phones. In addition, there are also pure SIP modules that can directly register with the SIP server and schedule calls for SIP intercom.
Integration of safety monitoring and comprehensive automation system: Customized development can achieve the sharing of relevant data of safety monitoring and comprehensive automation system. When gas exceeds the limit or the fan cannot work normally, the system will automatically issue a safety alarm in a specific area and command relevant personnel to take necessary measures.
Support complete GSI map management function, which can be combined with underground LED display screen to form a mine information guidance and release system
● Other functions
There are various types of sound sources: that can be traditional audio devices such as microphones, microphones, DVD/VCDs, or modern digital devices such as computers and MP3 players; When using a computer for playback, all digital voice files supported by the computer can be played, and network playback can also be supported. Mine leaders can speak to the underground radio through the computer in their office.
Power amplifier shutdown intelligence: When the audio module detects an audio signal, an IO pin will turn to high level to trigger the subsequent power amplifier to turn on. If the playback or intercom is completed, a delay of 3 seconds (adjustable) will turn to low level, and the control relay will turn off the power amplifier to realize energy conservation.
