Abstract
The utility model relates to a vision protection notebook computer having a sight distance measurement function and a brightness automatic control function, which comprises a central processing unit (CPU) of the notebook computer and a peripheral central control circuit controlled by the CPU; and the vision protection notebook computer is characterized in that: the CPU is connected with a detection signal processing unit, and the detection signal processing unit is connected with a distance measurement sensing module and a photoelectric sensing module. When a user approaches the computer, the user can be prompted and warned by sounds, at the same time, the automatic detection can be realized according to the environment variation, and the notebook computer can enter the best mode brightness range so as to adequately protect the eye vision of the human body. The notebook computer has a simple circuit structure and has a good practical value.
Description
Technical field
The utility model relates to the notebook computer technical field, particularly a kind of sight protectio notebook computer with the double brightness automatic control of sight line range finding.
Background technology
Notebook computer is to use more at present, and popularization is very high.User's age bracket is cross over old age from teenager.And teenager user crowd trend is very high, and it is also very long that they stared at the screen time in one day.If the user is too near to screen, the long-term use down can cause eye fatigue, even myopia.In addition, notebook computer is because of causing screen too bright or too during dark background under the ambient brightness changing condition, also can have a strong impact on user's eyesight and healthy.
Summary of the invention
In view of this, the utility model provides a kind of sight protectio notebook computer that the brightness automatic control is held concurrently in the sight line range finding that has.
The utility model adopts following scheme to realize: a kind of have a sight protectio notebook computer that the brightness automatic control is held concurrently in the sight line range finding, comprises the CPU of notebook computer and by control circuit in the periphery of this CPU control; It is characterized in that: described CPU is connected with the detection signal processing unit, and described detection signal processing unit is connected with range finding induction module and optoelectronic induction module.
Further, described detection signal processing unit comprises:
One compares amplifying circuit, and its output terminal is connected with said CPU;
One photoelectric switching circuit, its input end is connected with described optoelectronic induction module, and output terminal is connected with described relatively amplifying circuit; One range finding change-over circuit, its input end is connected with described range finding induction module, and output terminal is connected with described relatively amplifying circuit; And
One sample circuit, the input end of this sample circuit is connected with said CPU, and output terminal is connected with described relatively amplifying circuit.
Further, said range finding induction module is a ultrasonic ranging sensor.
The utility model can lean on when too closely using computer the user; The sound prompting warning users, it can also detect and get into optimal mode brightness range, the eye eyesight of general protection human body automatically according to environmental change simultaneously; Circuit structure is simple, has good practical values.
Description of drawings
Fig. 1 is the schematic block circuit diagram of the utility model embodiment.
Fig. 2 is the schematic block circuit diagram of another embodiment of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1, the utility model provides a kind of sight protectio notebook computer that the brightness automatic control is held concurrently in sight line range finding that has, and comprises the CPU of notebook computer and by control circuit in the periphery of this CPU control; It is characterized in that: described CPU is connected with the detection signal processing unit, and described detection signal processing unit is connected with range finding induction module and optoelectronic induction module.
Concrete, seeing also Fig. 2, described detection signal processing unit comprises: one compares amplifying circuit, and its output terminal is connected with said CPU; One photoelectric switching circuit, its input end is connected with described optoelectronic induction module, and output terminal is connected with described relatively amplifying circuit; One range finding change-over circuit, its input end is connected with described range finding induction module, and output terminal is connected with described relatively amplifying circuit; And a sample circuit, the input end of this sample circuit is connected with said CPU, and output terminal is connected with described relatively amplifying circuit.
In order to let those skilled in the art better understand present embodiment; Do further introduction in the face of the principle of work of present embodiment down: the optoelectronic induction module changes according to ambient brightness gathers light signal; And convert light signal to electrical signal transfer and carry out electric signal to the detection signal processing unit and relatively amplify; The CPU of notebook computer controls the backlight drive circuit of back level according to the signal of relatively amplifying circuit output, thereby realizes the automatic brightness adjustment of notebook computer display screen.
And the range finding induction module mainly obtains user's positional information relative with notebook computer; The information such as position distance whether user and user are arranged like notebook computer the place ahead; And this information is sent to the CPU of notebook computer through the detection signal processing unit processes; The fiducial value that this CPU is provided with according to system, control loudspeaker give a warning sound and on display screen the display alarm user be on the alert at present.
Here be noted that control circuit is the data message amount that special disposal CPU transmits in the described notebook of the utility model periphery, its effect comprises conversion of signals, network communication, voice output, image Presentation Function, and also promising CPU provides clock signal etc.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
