Abstract
The utility model provides a kind of automatic rotation display, comprise: camera, microprocessor, described camera is connected on microprocessor, described microprocessor is connected with stepper motor driving circuit, LED, power supply, switch, power supply is camera, microprocessor provides electric energy, and Microprocessor S3C44B0X stepper motor works.Whether the utility model can by camera monitor user ' in display dead ahead, can be made the display screen anglec of rotation accurately by stepper motor, thus make display screen face user at any time, and structure is simple, easy to implement, can be used for various display.
Description
Technical field
The utility model relates to display technology field, is specially a kind of automatic rotation display.
Background technology
Present life be unable to do without computer, be unable to do without TV, liquid crystal screen displays become our work with the instrument of amusement, in order to the Energy and comfort of work entertainment, LCD bracket is also have a lot, as wall, desktop, ground, screen, commercial unit, plant equipment etc.
No matter be which kind of support, shortcoming can not make LCD elevating height exactly automatically, the anglec of rotation, pendulum angle, angle of inclination thus obtain more suitably angle.Current TV, computer monitor, all larger, heavier, and mostly can not automatic rotation screen.
As patent CN201320599173, this is the rotary display screen adopting pivot design, the base of display is arranged at a support bar, described support bar adopts pivot design, the supporting bar top of rotating shaft is fixed with shell, the embedded display of shell, but this display needs manual rotation screen, cumbersome.
As patent CN201310753055, the mode of remote-control rotary screen is provided, by two signal receiving devices, according to the signal that the signal generation apparatus received is launched, calculate the leg-of-mutton angle of correspondence being considered as summit with two signal receiving devices and signal generation apparatus, according to angle, determine the inclination angle between signal generation apparatus and display pannel plane; When inclination angle is not within the scope of the inclination angle set, but controlling display pannel rotates. and this display can not, automatically along with the mobile automatic rotation screen of human body, when people's hand is in work or when not holding telepilot, just can not allow display rotate.
Meanwhile, be all passive rotation with upper type, can not rotate along with the movement of people in time.
Utility model content
The technical matters that the utility model solves is to provide a kind of automatic rotation display, to solve the problem proposed in above-mentioned background technology.
The technical matters that the utility model solves realizes by the following technical solutions: a kind of automatic rotation display, comprise: camera, microprocessor, described camera is connected on microprocessor, described microprocessor is connected with stepper motor driving circuit, LED, power supply, switch, power supply is camera, microprocessor provides electric energy, and Microprocessor S3C44B0X stepper motor works.
Described camera is infrared camera.
Described power supply is the switching power supply of multiple-channel output.
Compared with prior art, the beneficial effects of the utility model are: the utility model by camera can at any time monitor user ' whether in display dead ahead, the display screen anglec of rotation can be made accurately by stepper motor, thus make display screen face user, structure is simple, easy to implement, can be used for various display.

Embodiment
In order to make actualizing technology means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.
As shown in Figure 1, a kind of automatic rotation display, comprise: camera, microprocessor, described camera is connected on microprocessor, described microprocessor is connected with stepper motor driving circuit, LED, power supply, switch, power supply is camera, microprocessor provides electric energy, and Microprocessor S3C44B0X stepper motor works.
Described camera is infrared camera.
Described power supply is the switching power supply of multiple-channel output.
This device workflow describes as follows, this device has used image recognition technology, flow process is as figure six, after the utility model connects 220V civil power, be connected for camera, microprocessor power supply with the switching power supply of multiple-channel output, described LED is connected with microprocessor, shows this device and whether is in mode of operation.After switch opens, camera is started working, gather image around, the image of collection is sent in microprocessor, by microprocessor, successively denoising is carried out to the image of camera collection, equalization, sharpening, Iamge Segmentation, and extract characteristic information main in two width or multiple image, feature in coupling multiple image, identify main object, extract faceform, the image processed and facial image are compared, judge whether the image gathered is facial image, then the angle of place residing for user and display vertical line is judged, if user is not the dead ahead at display, Microprocessor S3C44B0X stepper motor rotates, until facial image is in the central authorities of the image of collection.Real-time user friendly work, study, amusement.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
