Embodiment
Along with information-based and digitized develop rapidly, the problem that existing multi-media platform exists also reveals gradually, especially for Art Design, flexible and changeable teaching, the free-hand skeletonizing in classroom, the forms such as material object display, by just seem heaviness especially of existing multi-media platform, complex operation, some lively classroom forms are restricted.
This Art Design multi-media platform has higher intellectuality, and it is more convenient to operate, and uses more flexibly, and man-machine interface is humanized, and has succinct light and handy appearance and modeling; Make multi-media platform become the strong aid of classroom instruction, make instructional mode more flexible and varied changeable, vividly abundant.
In order to make object of the present invention, technical scheme and advantage are clearer, illustrate below in conjunction with accompanying drawing:
Accompanying drawing 1 is Art Design multi-media platform structural representation, this Art Design multi-media platform comprises multiple point touching desktop assembly 1, desktop angle adjusting device 2, apparatus for automatically lifting 3, table leg mobile device 4, host computer control device 5 and micro projector 6, wherein desktop angle adjusting device 2 can carry out certain angular adjustment as required, make projected image clear, regulate the angle of desktop by desktop angle adjusting device 2, improve the comfortableness of desktop operated; Apparatus for automatically lifting 3 is by being built in the height sensor of desktop front end, automatic sensing-detecting user's height, by being preset at motor and the lead screw transmission mechanism in table leg, automatically carry out lift adjustment, the height of concrete desktop is determined according to the data of ergonomics;
As shown in Figure 2, multiple point touching desktop assembly 1 comprises multi-point touch panel 7, liquid crystal display 8, control panel 10, laser infrared line writing pencil 12, wireless Mike 13 and various port interface 11; Wherein multi-point touch panel 7 can be as required complete operation at an arbitrary position, interface operation is convenient, hommization; Liquid crystal display 8 is controlled by host computer control device 5, shows various application programs, and picture is clear; Control panel 10 is core operation regions, there is opening and closing button above, when pressing while releasing the button, there will be password identification frame, then just can enter system, on control panel 10, write the title of each button exactly, carry out as required the operation of height, angle, movement, procedure Selection, convenient and swift; Laser infrared line writing pencil 12, user can use according to custom and special requirement, can directly on touch-screen, use writing pencil, also can open mapping software, directly carry out the scene drafting of sketch with writing pencil, the other end of pen has LED lamp simultaneously, can be used as teaching indication use; Port interface 11 is the difference of the entrained memory device of compatible user to greatest extent, allows and uses hommization more; Wireless Mike 13 is built in desktop, can amplify clearly lecturer's sound, makes to explain effect more lively.
As shown in Figure 3, desktop angle adjusting device 2 comprises electric pushrod hinge 14, electric pushrod 15, and electric pushrod bearing hinge 16, wherein electric pushrod hinge can carry out according to the button on control panel 10 adjusting of certain angle; Electric pushrod 15, in regulating, the power of push rod drives hinge to move, thereby makes desktop certain angle that tilts; Electric pushrod bearing hinge 16, electric pushrod 15 is fixed on bearing, and in the time of angular adjustment, the hinge on bearing also moves, and coordinates the complete angled adjusting of push rod.
Apparatus for automatically lifting 3 is mainly a micro-step motor and one group of lead screw gear, the height of measuring according to sensor, and control system control motor is realized the lifting of desktop.
Whether table leg mobile device 4, by the control panel 10 of desktop, can select table leg to move as required, and the pulley under table leg, with lock function, moves to behind the position needing, and locks;
Host computer control device 5, after releasing the button on startup control panel, host computer control device 5 starts thereupon; The wherein built-in default various control programs of host computer control device;
Micro projector 6, be built in desktop, this micro projector 6 itself has the adjusting of micro projection angle, when projection angle regulates when less, by regulating micro projector 6 projection angles own to meet the sharpness of projection, and in the time that micro projector 6 needs the projection angle that regulates larger, need to regulate desktop angle adjusting device 9, by the operation of control panel 10, the desktop that user can carry out certain angle as required regulates, thereby improves the sharpness of projector projection;
4 Art Design multi-media platform course of work schematic diagram is described in further detail the course of work of the present invention with reference to the accompanying drawings,
This Art Design multi-media platform of platform is in the time pressing releasing the button on control panel 10, and prompt cipher identification on display screen, after the password of input is correct, enters operation interface; If password bad, prompting is inputted three times at most, if failure, system automatic shutdown;
Correct when Password Input, host computer control device starts, and corresponding program and equipment also bring into operation; The height induction device of desktop is also opened thereupon automatically, by the height sensor of desktop front end, automatically respond to user's height, and drive the built-in screw mandrel of table leg to carry out height adjusting, make platform adjust to a comfortable use height, changing foundation can be with reference to shown in accompanying drawing 5;
In liquid crystal display, occur operation interface, because whole desktop has been covered with a multi-point touch panel, operation interface can operate by multiple point touching, also can operate with writing pencil, according to user's custom with need to select; Writing pencil is placed on the right of desktop, takes all very convenient.Writing pencil is infrared laser writing pencil simultaneously, and laser instrument has been installed in one end, and when all right conduct explanation, assistant teaching aid uses.
In host computer control device, have pre-designed running program, user, according to operation interface, can select corresponding program, if there is the memory device carrying, has various interface selective in the both sides of control panel.Farthest contain multi-form memory device, guarantee to use convenient.In the time opening plotter program, can use writing pencil, draw at the scene of carrying out sketch nimbly and freely, makes teaching form more directly perceived lively.
On control panel, be also provided with other buttons.In the time that needs desktop has certain angle of inclination, can press angular adjustment button, by "+" with "-" can carry out the adjusting of several angle progression.Cooperatively interacting of the push rod that desktop carries and push rod hinge, smoothly complete angled regulation and control.
Projection regulates button, can control the high definition micro projection equipment being built in desktop, can regulate the sharpness of image and the angle of projection, guarantees that image can completely show clearly.
In addition, also have built-in wireless Mike, the Mike on control panel regulates button, " carries out the adjusting of volume and the adjusting of audio by "+" with ".Guarantee speaker's sound can clear loud and clear reception and registration out.
Table leg lower end also has movably pulley, by the movement on control panel and two buttons of locking, controls according to the needs that use.Such form makes platform have more changeable dirigibility, can give teaching person and more select, and makes the form of giving lessons more lively, abundant.
