Utility model content
For the shortcomings and deficiencies of prior art, the utility model aims to provide a kind of long transmission distance, antijamming capability is strong, monitor state is wide, be convenient to the digital locomotive vehicle-mounted video monitor watched and firebreak device.
The technical scheme that the utility model adopts is: a kind of high-definition digital formula locomotive vehicle-mounted video monitor and firebreak device, it comprises the display and several video camera that are installed on train A, B Che Jienei respectively, several video camera of A Che Jienei is connected with Vehicular video main frame, and the digital signal that Vehicular video main frame receives several video camera is gone forward side by side after row relax and is sent to connected display; Several video cameras of B Che Jienei are connected with switch, and digital signal is sent to described Vehicular video main frame by switch by several video cameras of B Che Jienei.
As preferably, described several video camera inside is equipped with a central processing unit, and central processing unit converts the video signal of collection to described digital signal and is sent to Vehicular video main frame.
As preferably, also comprise the fire alarm control unit be connected with Vehicular video main frame.
As preferably, Vehicular video main frame is connected with the TAX case of locomotive and obtains engine number, driver number, kilometer post, speed, train number, time, channel number information.
As preferably, each Vehicular video main frame is connected with electrical locomotive power.
The beneficial effect that the utility model produces is:
1, the central processing unit that video camera inside described in the utility model is provided with converts the video signal of collection to digital signal and is sent to Vehicular video main frame, the digital signal that Vehicular video main frame receives several video camera is gone forward side by side after row relax and is sent to connected display, the display resolution height 5-6 of figure is gathered doubly, the situation at each position of understanding locomotive enabling driver and conductor more clear and intuitive than analog video camera;
2, the utility model is by being provided with Vehicular video main frame and a switch, achieves the supervision to local video and condition of a fire state, long-distance video and condition of a fire state;
3, the utility model can be added to each image from the information such as locomotive TAX case harvester license number, driver number, kilometer post, speed, train number, time in real time by Vehicular video main frame.
Accompanying drawing explanation
Fig. 1 is each outfit of equipment connection layout of the utility model.
Embodiment
Describe the utility model in detail below in conjunction with Fig. 1, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.
