Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, be the schematic diagram of taxi top information display system embodiment of the present invention, it shows for the content such as advertisement that realizes taxi top.Above-mentioned taxi top information display system comprises wireless transmit/receive units 11, main control unit 12, screen body control module 13 and display screen 14, and above-mentioned display screen 14 is installed in the roof of taxi, carries out the mobile broadcasting of content thereby can follow taxi.Wireless transmit/receive units 11, main control unit 12, screen body control module 13 can be installed in taxi, and can be positioned at same printed circuit board (PCB) (realizing in conjunction with corresponding software).And above-mentioned wireless transmit/receive units 11, main control unit 12, screen body control module 13 and display screen 14 can be by the storage battery power supplies in taxi.
Wireless transmit/receive units 11 is for receiving play content and the broadcast strategy from remote control table by wireless network.Wherein 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 14 and parameter modification.Above-mentioned wireless network can be realized data transmission, specifically can adopt GPRS network, 3G network or 4G network etc.
Screen body control module 13 makes display screen 14 show corresponding play content for basis from the display of main control unit.Especially, this display screen 14 comprises multiple LED luminotrons and has two display planes, shields body control module 13 and comprises sub-controller, decoding subelement and driven element unit, and wherein sub-controller is for receiving the display from main control unit; Decoding subelement generates the decoded signal of LED luminotron according to display; Driven element unit is for showing image or word according to decoded signal driving LED luminotron.
Above-mentioned taxi top information display system is by receiving broadcast strategy and the play content from remote control table, can carry out Play Control to taxi top display screen easily, thereby the convenient maintenance to play content, is convenient to unified information and plays (avoiding driver to change without authorization play content).
As shown in Figure 2, main control unit 12 comprise can one igniting recognin unit 121, this igniting recognin unit 121 is for detecting the ignition signal of hiring a car.Particularly, above-mentioned igniting recognin unit 121 can gather from Vehicular system, by obtaining after shaping filter and digital-to-analog conversion.Main control unit 12 in igniting recognin unit 121 while recording ignition signal to screen body control module 13 output display signals otherwise stop to screen body control module 13 output display signals; Screen body control module 13 only makes display screen 14 show corresponding play content in the time of the display receiving from main control unit 12.
By igniting recognin unit 121, can make display screen 14 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 main control unit 12 also can comprise speed of a motor vehicle recognin unit 122, and this speed of a motor vehicle recognin unit 122 is for detecting the travel speed of hiring a car.Particularly, above-mentioned speed of a motor vehicle recognin unit 122 can gather from Vehicular system, by obtaining after shaping filter and digital-to-analog conversion.The travel speed that main control unit 12 records at speed of a motor vehicle recognition unit 122 for example, stops while being more than or equal to first threshold (70km/h) to screen body control module 13 output display signals otherwise to screen body control module 13 output display signals, and screen body control module 13 only makes display screen 14 show corresponding play content in the time of the display receiving from main control unit 12.
Due in the time that the speed of a motor vehicle exceedes certain value, the play content that common pedestrian cannot identification display screen 14, and for the driver of other vehicles, the play content of display screen 14 likely causes interference, therefore now the content play of display screen 14 is meaningless.By the vehicle speed signal collection of speed of a motor vehicle recognin unit 122, can make display screen for example, in the time that the speed of a motor vehicle is more than or equal to assign thresholds (70km/h), automatically close display screen; In the time collecting the speed of a motor vehicle lower than assign thresholds, then make display screen 14 recover to show (for example, in gradually bright mode).
In addition, main control unit 12 also can comprise Photoinduction device 123, and this Photoinduction device 123 is for detecting ambient light intensity and being converted into electric signal.The light intensity regulation output that main control unit 12 records according to Photoinduction device 123 is to the display of screen body control module 13, makes to shield body control module 13 and regulate the brightness of display screen.
As shown in Figure 3, be the schematic diagram of taxi top method for information display embodiment of the present invention, show for the content such as advertisement that realizes taxi top.The method comprises the following steps:
Step S31: receive broadcast strategy and the play content from remote control table by wireless network.Wherein remote control table comprises control computing machine and software platform, and controlling computing machine can be by software platform to play content and parameter modification.Above-mentioned wireless network can be realized data transmission, specifically can adopt GPRS network, 3G network or 4G network etc.
Step S32: generate display according to the broadcast strategy receiving in step S31 and play content.For example, in the time that above-mentioned play content comprises many advertisements, the displays such as genesis sequence broadcasting after can many advertisements being sorted by broadcast strategy, loop play.
In this step, also can be used as generating by detecting the ignition signal of hiring a car the foundation of display, only in the time recording ignition signal, generate display otherwise do not generate display.Thereby the display screen content that do not display the play in the time that taxi is not lighted a fire.
In this step, also can generate different displays by detecting the travel speed of hiring a car, only in the time that the travel speed recording is less than first threshold, generate display otherwise do not generate display.Thereby only the speed of a motor vehicle of taxi during lower than first threshold display screen just open.
In addition, in this step, also can carry out brightness of display screen adjusting according to ambient light intensity, detect ambient light intensity and the light intensity recording is converted to electric signal by a Photoinduction device, then regulate display to regulate the brightness of display screen.
Step S33: make display screen show corresponding play content according to the display generating in step S32, wherein above-mentioned display screen is attached to the roof of taxi.
Above-mentioned display screen comprises multiple LED luminotrons, and correspondingly, this step comprises: receive display; Generate the decoded signal of LED luminotron according to display; Show image or word according to decoded signal driving LED luminotron.
The above; only for preferably embodiment of the present invention, but protection scope of the present invention is not limited to this, is anyly familiar with in technical scope that those skilled in the art disclose in the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
