Description
Technical field
The present invention relates to air-conditioning, particularly relate to air-conditioning and the method for automatic adjusting display brightness.
Background technology
The display of current air-conditioner mostly is the displaying scheme of constant brightness, or is that display brightness is adjustable, but needs artificial setting.Also there is no the air-conditioning of energy automatic regulating lightness.Therefore, when environment for use light is stronger, display screen may be darker; And when dark, display screen is too dazzling again, or complicated operation needs people to participate in, and can not automatically change.Such as: when rest at night, room light is comparatively dark, and the brightness of display screen of air-conditioner is too bright, affects sleep quality; After closing display screen, user can not understand running state of air conditioner in time.
Summary of the invention
The technical problem to be solved in the present invention is: the air-conditioning and the method that provide a kind of automatic adjusting display brightness, makes air-conditioning automatically can regulate the brightness of display screen according to the light intensity of environment for use.
For solving the problem, the technical solution used in the present invention is: the automatically air-conditioning of adjusting display brightness, comprise be connected in turn with lower part: photoinduction unit, microprocessing unit, control unit, display unit;
Photoinduction unit for detecting light intensity, and exports the analogue value;
Microprocessing unit for receiving the analogue value, and is converted into accurate data signal, and aligning data signal is optimized and obtains data signal, data signal and preset value is made a decision, and exports control signal;
Control unit is used for reception control signal, and output drive signal;
Display unit is for receiving drive singal and display brightness.
Further, described photoinduction unit comprises multiple sensor.
Further, described drive singal is PWM (Pulse Width Modulation, pulse width modulation) drive singal.
The method of automatic adjusting display brightness, comprises the following steps:
A. photoinduction unit detects the light intensity of diverse location simultaneously, and exports the analogue value of correspondence position light intensity;
B. microprocessing unit receives the analogue value, and be as the criterion the analogue value conversion data signal, and aligning data signal is optimized and obtains data signal, and data signal and preset value is made a decision, and exports control signal according to judged result;
C. control unit reception control signal, and export PWM drive singal;
D. display unit receives PWM drive singal, display corresponding bright.
Further, the concrete grammar optimized described in step b is that multi-group data is averaged, and formula is as follows:
Wherein, DATA is data signal, and x is the time, and y is number of sensors, and YiDATAj is that y sensor detects and the accurate data signal changed in xth second.
Be further, the method judged in step b is: as DATA≤T1, exports the first control signal, as T2 >=DATA ﹥ T1, export the second control signal, the like, as Tn >=DATA ﹥ Tn-1, export the n-th control signal, as DATA>Tn, export the (n+1)th control signal, n is the number of preset value, and Tn is the n-th preset value.
The invention has the beneficial effects as follows: by the photoinduction unit inspection light different situations of air-conditioning, through microprocessing unit conversion and process, again through the display and control of control unit to display unit, the light intensity that the display brightness of air-conditioning conforms automatically, improves the comfortableness using and watch of user; Meanwhile, show dazzling problem when solving rest at night, improve sleep quality.
Accompanying drawing explanation
Fig. 1 is the block diagram of the embodiment of the present invention;
Fig. 2 is embodiment of the present invention workflow diagram.
Detailed description of the invention
As Fig. 1, air-conditioning of the present invention comprise time to link together with lower part: photoinduction unit, microprocessing unit, control unit, display unit; Photoinduction unit for detecting light intensity, and exports the analogue value; Microprocessing unit for receiving the analogue value, and is converted into accurate data signal, and aligning data signal is optimized and obtains data signal, data signal and preset value is made a decision, and exports control signal; Control unit is used for reception control signal, and output drive signal; Display unit is for receiving drive singal and display brightness.
For increasing reliability and accuracy, multiple sensor can be set in photoinduction unit, detect the light intensity of diverse location, and export the analogue value of correspondence position light intensity in real time, first the analogue value of diverse location is converted to the poor accurate data signal of accuracy, then by the accurate data signal summation of each position conversion after when one section, finally the accurate data signal of all positions averaged and obtain reliability and the higher data signal of accuracy, the formula of optimization is as follows;
Wherein, DATA is data signal, and x is the time, and y is number of sensors, and YiDATAj is that y sensor detects and the accurate digital signal value changed in xth second.
The detailed process of the embodiment of the present invention as shown in Figure 2, photoinduction unit detects light intensity in the environment, export the analogue value, and by this Signal transmissions to microprocessing unit, data signal DATA is converted to according to input value, and this data signal DATA is made a decision from preset value T and exports different control signal COMMAND, different control signal COMMAND passes to control unit, then control unit exports the PWM drive singal of different duty, display unit receives the PWM drive singal of different duty, shows different brightness.
The determination methods of data signal and preset value is: as DATA≤T1, exports a control signal COMMAND1, as T2 >=DATA ﹥ T1, export a control signal COMMAND2, the like, as Tn >=DATA ﹥ Tn-1, export a control signal COMMANDn.As DATA>Tn, export a control signal COMMANDn+1.Regulate initial T1 and Tn to arrange and enter minimum and threshold value that is maximum brightness, being arranged on preset value T by remote controller is increased or reduction threshold value, to adapt to the crowd of not photosensitive demand.T value changes by remote controller signaling, and initial value is 0, and step value can be set to according to actual conditions ± 1 or ± 5 etc.
Embodiment:
Certain air-conditioning sensor be arranged in working space detects the analogue value of 0-4.2V, and the value 0-4.2V of detection is transferred to microprocessing unit by photoinduction unit, and the value of detection is converted to data signal DATA=00000000 ~ 11111111 by micro-process; Determination methods by data signal and preset value: work as DATA<T1=00000010, exports control command 1XXX1000, and it is 1/16 that control unit exports PWM, is shown as the darkest brightness; As T2=00000100 >=DATA ﹥ T1=00000010, export control command 1XXX1001, it is 2/16 that control unit exports PWM, shows slightly brighter than before As Tn=1111000 >=DATA ﹥ Tn-1=1110000, export control command 1XXX0110, it is 13/16 that control unit exports PWM, and display becomes brighter state; As DATA ﹥ Tn=11111100, export control command 1XXX1111, it is 14/16 that control unit exports PWM, is shown as the brightest state.Air-conditioning realizes the automatic adjustment of display brightness by aforementioned process.
Just explain through diagrams described in above it is pointed out that principles more of the present invention, is easy to carry out some amendments and change on this basis due to the those of ordinary skill concerning constructed field.Therefore, this description be not the present invention to be confined to shown in and in described concrete structure and the scope of application, therefore every corresponding modify of being likely utilized and equivalent, all belong to the scope of the claims that the present invention applies for.
