Fig. 1 is the signals collecting of display screen and the schematic diagram of transmission of a kind of automatic regulating lightness of the utility model;
Fig. 2 is the ambient light illumination of display screen and the linear relationship chart of brightness of display screen of a kind of automatic regulating lightness of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the utility model can combine mutually.
Basic thought of the present utility model is: in conjunction with excavator, with display screen, by optical sensor, gather the corresponding signal of telecommunication of ambient light illumination, through A/D, conversion sends signal to display screen by CAN bus, display screen carries out D/A conversion again, according to illumination and brightness relationship, export different magnitudes of voltage and light diode.Thereby reach the object of automatic regulating lightness, without operator, carry out manual adjustments, increase work efficiency.
Below in conjunction with accompanying drawing, each preferred embodiment of the present utility model is described further:
With reference to Fig. 1-2, it shows the display screen embodiment of automatic regulating lightness of the present utility model, comprise optical sensor, controller and display panel, optical sensor is connected with controller, and controller is connected with display panel, and controller is provided with the AI mouth for collection signal, controller passes through CAN bus to display panel transmission of signal, display panel is exported different voltage by signal, and display panel comprises LED backlight, and LED backlight sends the light of different brightness according to the different voltages of display panel output; Optical sensor, controller, display panel participate in the control mode that signal transmits simultaneously, and controller gathers brightness, and the signal of telecommunication collecting is sent to display screen, and display panel is lighted LED diode by the different voltage of signal of telecommunication size output.
Preferably, in the various embodiments described above, wherein the collection of ambient light illumination is as follows: it is 10 that ambient light illumination is gathered to optical sensor identification, i.e. 2 10 powers, 1024.Be that 5V is the brightest, identification is about 5 millivolts.Controller carries out AD conversion by analog acquisition to the magnitude of voltage of corresponding illumination, gather register and be also 10, the signal voltage transitions collecting is that digital quantity is 0-1023, as to gather voltage be 2.5V, be that after AD changes, numerical value sends to display panel into 512, display panel, by inner DA conversion chip/circuit, converts this digital quantity to analog quantity again.
