Monitor in real time, needs multiple stage display just to enable, and traditional display volume is big, do not have explosion-proof and antidetonation work(
Can, be not suitable for underground coal mine.
Content of the invention
The problem existing for above-mentioned prior art, this utility model provides a kind of mine explosion-suppression escope, Neng Goushi
The now monitor in real time to multiple monitoring points simultaneously.
To achieve these goals, a kind of mine explosion-suppression escope that this utility model adopts is it is characterised in that described
Display includes the housing being welded into by stainless steel material, and described enclosure interior forms a flame proof cavity, described flame proof cavity
Inside it is provided with the energy supply control module for driving the work of display interior modules, video optical signal is converted into video telecommunication
Number Optical Receivers, the multi-channel video signal of telecommunication is synthesized the picture segmentation module and be used for showing that multichannel regards of a road video image
The liquid crystal display of frequency image；The outfan of described energy supply control module splits module and liquid with Optical Receivers, picture respectively
Crystal display connects；The input of described Optical Receivers accesses video optical signal, and the outfan of described Optical Receivers connects
Split the input of module to picture, the outfan of described picture segmentation module is connected to the input of liquid crystal display.
Described picture segmentation module adopts 4 image splitters.
Described Optical Receivers adopts optical transmitter and receiver.
Described housing is provided with the transparent observing window for observing display image.
Described liquid crystal display uses industrial liquid crystal display.
Compared with prior art, this utility model compact conformation, volume is moderate, explosion-proof, intrinsic safety, antidetonation, moistureproof, suitable coal
Use under mine；Can realize for multi-channel video optical signal being converted into video electrical signal entering using multiple Optical Receivers simultaneously
Enter the picture segmentation module of display interior, synthesis one road video image shows on a liquid crystal display, can observe simultaneously
Multiple paths of video images is it is achieved that monitor in real time to multiple monitoring points.

It is provided with the energy supply control module 6 for driving the work of display interior modules in 2, video optical signal is converted into video electricity
The Optical Receivers 3 of signal, Optical Receivers 3 uses optical transmitter and receiver, and the multi-channel video signal of telecommunication is synthesized a road video image
Picture split module 4 and for showing the liquid crystal display 5 of multiple paths of video images, described liquid crystal display 5 uses work
Industry liquid crystal display, can be applied to rugged environment under mine；Described picture segmentation module 4 adopts 4 image splitters,
Image clearly, video recording, monitor in real time are carried out simultaneously；The outfan of described energy supply control module 6 respectively with Optical Receivers 3, draw
Face segmentation module 4 and liquid crystal display 5 connect, and provide the unidirectional current of 12V for modules；The input of energy supply control module 6
Access the alternating current of mining 127V；The input of described Optical Receivers 3 accesses video optical signal, described Optical Receivers 3
Outfan is connected to the input that picture splits module 4, and the outfan that described picture splits module 4 is connected to liquid crystal display 5
Input.
During work, user is incorporated into display interior four road video optical signals of outside input, connects with four light respectively
The input terminal receiving module 3 is connected.Then with mine cable mining AC127V alternating current introduce this product internal with
AC127V terminal is connected and can use.Four road video optical signals enter this display, the Optical Receivers 3 with display interior
Connect, enter the picture segmentation module 4 of display interior after being converted into video electrical signal, synthesis one road video image is in liquid crystal
Show on device 5, now can observe four road video images simultaneously.
Finally it should be noted that：The foregoing is only preferred embodiment of the present utility model, be not limited to this practicality
New, although with reference to the foregoing embodiments to this new be described in detail, for a person skilled in the art, its according to
