4, do not having under the situation of cable network, can realize by 3G (4G) network and satellite network the independent operating of real realization equipment.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
The two-way audio frequency and video transmission equipment of a kind of mobile emergency comprises equipment box, and is arranged on display screen 6, public address sound equipment 2, video acquisition device 3, audio collecting device 4, codec 9, power module and wireless communication module in the equipment box.Electric connecting relation between the above-mentioned parts is: codec 9 connects display screen 6, public address sound equipment 2, video acquisition device 3, audio collecting device 4 and wireless communication module respectively, and power module connects display screen, public address sound equipment, video acquisition device, audio collecting device, codec and wireless communication module respectively.
Power module comprises at least two lithium battery groups 10, hand-rail type generator 8 and current overload protection protection unit, and hand-rail type generator 8 inserts lithium battery group 10 by the current overload protection protection unit.Like this can the standby system power supply, after a power supply broke down therein, another power supply can start immediately.The hand-rail type generator of Pei Beiing in addition, i.e. energy-conserving and environment-protective do not worry that the consumptive material that generator uses exhausts yet.The hand-rail type generator can unconfinedly generate electricity, and does not worry quantity problem; To lithium battery group charging device the current overload protection protection unit is installed at generator, is avoided hand excessive velocities to produce big electric current.
Wireless communication module comprises that satellite network accesses terminal 7 and 3G or 4G network insertion terminal 1, by accessing terminal of two kinds of wireless networks, solved the problem of network transmission, image and transfer voice with the scene that can be real-time at emergent accident scene arrive main meeting-place or other meeting-place, to make things convenient for leading body at a higher level to understand the on-the-spot situation of emergent burst timely and in time link up, only can a coordination personnel to make corresponding solution fast and to convey to on-the-spot being responsible for fast.
The concrete structure of entire equipment as shown in Figure 1; equipment box comprises casing 12 and case lid 11; casing 12 and case lid 11 are hinged; display screen 6, public address sound equipment 2, video acquisition device 3, audio collecting device 4, satellite network access terminal 7 and 3G or 4G network insertion terminal 1 be arranged on the case lid 11, codec 9, lithium battery group 10, hand-rail type generator 8 and current overload protection protection unit are arranged on the casing 12.
In order to save the energy consumption of whole device, increase continuation of the journey, video acquisition device, display screen, audio collecting device and public address sound equipment are preferably selected the product of some low energy consumption, wherein, video acquisition device can adopt microcam, audio collecting device can adopt microphone, and display screen can adopt LCDs.Codec employing basis H.323 protocol development goes out codec chip and the video conference application mainboard of the audio frequency and video transmission of novel high compression, in addition, can also in the conventional video conference terminal, be improved, remove the redundancy function (as double fluid, two apparent videos, unnecessary audio interface) of existing video conference terminal, to realize low power consuming, efficient; Assurance equipment is long-time continuation of the journey participating in emergent burst meeting.
