Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model taxi top display device embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, be the schematic diagram of the utility model taxi top display device embodiment.In the present embodiment, this taxi top display device comprises mounting bracket, casing 10, display screen 30, wireless transmit/receive units and control module, and wherein casing 10 is fixed on the top of taxi by mounting bracket; Display screen 30 comprises that laying respectively at first on casing 10 screen and the second screen and this first screen and second shields respectively a side towards taxi; Wireless transmit/receive units by wireless network (such as GPRS network, 3G network or 4G network etc.) receive from remote control table (this remote control table comprises and controls computing machine and software platform, control computing machine can be by software platform the play content to display screen and parameter modification) play content and broadcast strategy; The content that the play content that control module receives by the storage battery power supply of taxi and according to wireless transmit/receive units and broadcast strategy are controlled respectively the first screen and the second screen shows.Above-mentioned wireless transmit/receive units and control module can be positioned at same printed circuit board (PCB), and it can be installed in casing 10 or be installed in taxi.
Above-mentioned taxi top display device, by receiving broadcast strategy and the play content from remote control table, can be carried out Play Control to taxi top display screen easily, thus the mobile broadcasting of the information of realization (for example advertising message).
Mounting bracket is fixed to roof, and it comprises that the two ends of two mounting rails that be arranged in parallel 21 and each mounting rail 21 have respectively a jaw 22.Each mounting rail 21 is affixed on taxi top and perpendicular to length of wagon direction, two jaws 22 are sandwiched in respectively the both sides (for example doorframe place) of vehicle body, casing 10 is bolted mounting rail 21(and for example in the bottom of casing 10, outstanding mounting ear is set, and bolt is fixed to mounting rail through above-mentioned mounting ear).By this structure, can realize the installation of casing 10 without the operation of the destruction body structures such as vehicle body is holed.And this mounting support structure is also convenient to dismounting and maintenance.
Above-mentioned casing 10 is trapezoidal along the cross section of taxi Width, and two trapezoidal waists are made up of the first screen and second screen of display screen 30 respectively.The lower dimension that is casing 10 is greater than upper dimension.Particularly, the length of these casing 10 bottoms is that 0.8-1.4 rice, width are that 0.15-0.3 rice, height are 0.2-0.4 rice, and the undersized at top is in the size of bottom.And the first screen and the second screen occupy respectively the more than 80% of area of the side of place casing 10.
Especially, the top of above-mentioned casing 10 has the Photoinduction device 11 for detecting ambient light intensity, and this Photoinduction device 11 is connected to control module, thereby the light intensity that control module can record according to Photoinduction device 11 regulates the brightness of the first screen, the second screen, in the clear content that displays the play, save the energy.
Above-mentioned control module also can be connected to the ignition signal lead-out terminal of Vehicular system and show according to output signal control first screen of ignition signal lead-out terminal and the content of the second screen.Particularly, ignition signal can gather and by obtaining after shaping filter and digital-to-analog conversion from Vehicular system.Control module makes the first screen and the second screen display show play content in the time recording ignition signal, makes the first screen and the second screen close in the mode of going out gradually if do not record ignition signal.Identify by ignition signal, can make display screen 30 only after taxi igniting, just open (for example with gradually bright mode open), thereby avoid the electric quantity consumption of taxi accumulator, also make taxi only in the time flowing operation, carry out information demonstration simultaneously, strengthen result of broadcast.
Above-mentioned control module also can be connected to the vehicle speed signal lead-out terminal of Vehicular system and show according to output signal control first screen of vehicle speed signal lead-out terminal and the content of the second screen.Similarly, vehicle speed signal gathers and by obtaining after shaping filter and digital-to-analog conversion from Vehicular system.Control module for example, makes display screen 30 close, in the time that the speed of a motor vehicle recording is less than first threshold, make display screen 30 open and play corresponding play content in the mode of going out gradually in the time that the speed of a motor vehicle recording is more than or equal to first threshold (70km/h).Due in the time that the speed of a motor vehicle exceedes certain value, the play content that common pedestrian cannot identification display screen 30, and for the driver of other vehicles, the play content of display screen 30 likely causes interference, therefore now the content play of display screen 30 is meaningless.By adjust the broadcasting of display screen 30 according to the speed of a motor vehicle, can make display screen 30 for example, in the time that the speed of a motor vehicle is more than or equal to assign thresholds (70km/h), automatically close; In the time collecting the speed of a motor vehicle lower than assign thresholds, then make display screen 30 recover to show (for example, in gradually bright mode).
Because the thermal value of display screen 30 itself is larger, therefore can make to there is gap between the bottom of casing 10 and taxi top, and the bottom of casing 10 have air feed shutter window and air-out window shutter.By said structure, not only can realize display screen heat radiation, and can ensure that casing 10 inside do not intake.
In above-mentioned taxi top display device, casing 10 rear and front ends can have respectively backlight, and this backlight is connected to control module luminous by control module control.This backlight can illuminate the graph text information of tank ends silk-screen.
The above; it is only preferably embodiment of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
