The course of work is：After relief group reaches mine disaster scene, quickly set up in ground emergency management and rescue commander The heart, sets up ground central apparatus, establishes ground level-one command centre.Then begin to by two teams rescue personnel (per squad 6-9 people) Carry the equipments such as underground base equipment, trunking, disaster area headend equipment, mining flame-retardant optical cable and enter downhole safety region, Emergent underground base is established in safety zone in tunnel, is laid with the base equipment that rescue team member carries, carries out corresponding deployment After work, stayed by one group of personnel and carry disaster area headend equipment with here as underground two level command centre, another group of personnel Continue to set out after equipment and advance to the condition of a disaster region, lay trunking on the way and keep communication normal.

Disaster area scene by thermal infrared imager, microphone, sensor acquisition module by the video/audio collected, CO, CH4, The environmental parameters such as O2, temperature are transmitted to multimedia signal processing device, information are divided into two yards after compressed, coding, main bit stream is deposited Storage is sent to trunking, trunking in miniature electronic memory module, subcategory number stream by wireless WIFI radio-frequency modules and antenna Have again through radio-frequency module and antenna transmission to next trunking up to being transferred to underground base equipment, while can also use The mode of linear light fibre transmits information data to underground base, is reduced into audiovisual information through underground base equipment and shows.

Digital signal is reduced into underground base computer audiovisual information and environmental parameter visualization is shown, intuitively Ground shows rescue personnel, while can continue through wirelessly or non-wirelessly mode and transmit the information to ground central apparatus, ground meter Calculation machine is reduced into video and audio material and environmental parameter is checked, and is realized and underground base, underground by wireless radio frequency modules Single bidirectional communication is commanded between base and disaster area front end.

When data packet is transmitted to the trunking nearest from underground base, may continue to by mining wired optical cable transmission To underground base equipment, can also be sent by the 2.4GHz wireless radio frequency modules and antenna of trunking to underground base 2.4GHz Wireless radio frequency modules.The video and environmental parameter for restoring digital signal through ARM9 microprocessors in intrinsic safety computer are illustrated in electricity On brain display screen, voice is played by intrinsic safety type headset.Meanwhile underground base equipment is also by wired optical cable or wireless The wire/wireless that 2.4GHz radio-frequency modules and 2.4GHz radio-frequency antennas deliver a packet to ground rescue base adaptively takes Business device, is reduced into voice, video and ambient parameter information observation and underground base and front end rescue team member is commanded.

Ground command center at any time realizes the WLAN devices around the condition of a disaster Information Pull communication truck received Data access, these data are linked into national (province) by VSAT satellite channels by wireless image transfer device (individual soldier) and rescue Command centre, the wherein form of satellite communication transmission data are IP bags, support ICP/IP protocol, need to only connect satellite equipment with referring to Data can be transmitted by waving the information network router at center.Ground rescue command personnel can enter in communication truck, pass through in-car Video camera participating television meeting, the configurating terminal of video conferencing are linked into state host by VSAT satellite channels and stand, state host station It is equipped with the H.323 MCU of agreement and is linked into the TV conference system of national emergency management and rescue command centre, that is, rescues communication truck with regard to phase When in the remote site of TV conference system, realized in a manner of satellite communication.In entirely rescue communication commanding system, Single bidirectional communication between each headquarter is as shown in Figure 2：I.e. field data unidirectional delivery in disaster area refers to downhole rescuing base, ground Wave center and national rescue center, and national rescue center and ground command center, ground command center and downhole rescuing base, Two-way communication can be carried out between downhole rescuing base and disaster area rescue site, do not set up skip grade communication be for convenience it is at different levels between Commander understands, avoids commander's instruction communication confusion in channel.

The scope of protection of the utility model is not limited to specific embodiment of the present utility model, for the skill of the art For art personnel, under the enlightenment of the utility model, directly can exporting association from the utility model disclosure, some are former The reason basic deformation identical with structure, or the replacement of common known technology in the prior art, and identical mutually different of feature Combination, the technical characteristic of same or similar technique effect simply change, especially the application technology and product in coal spontaneous combustion, all belong to In the protection domain of the utility model technology.
