Abstract
The invention discloses a remote-control video display bench for teaching. The display bench comprises a base with a backlight plate. An LCD video monitor and a control bench with a built-in rechargeable power supply are arranged on the base. The LCD video monitor is connected with the control bench. An infrared receiving device is arranged on the control bench and is connected with an infrared remote controller. A desk light neck which can be twisted and bent is fixed on the top of the control bench and a machine head is fixed to the desk light neck. A CCD lens is disposed on the end of the machine head. Light supplement lamps with desk light necks are arranged on two sides of the control bench.

Scanner in the market presses the difference of photo-electric conversion element, is generally CCDChargeCoupledDevice, photoelectricity coupling inductor scanner.Light signal on CCD, is converted to electric signal imaging by lens focus by it, and the latter is close to the scanning that contact is carried out on scanning contribution surface.Ccd scanner, by direct exposure in lens focus to CCD, can carry out material object scanning very easily.In scanner, sensor devices CCD is a kind of technology of comparative maturity, and its cost is lower, and image quality is but more and more higher, and some even can compare favourably with the photomultiplier that uses in rotating drum image scanner, has high cost performance.Adopt the requirement of CCD to ambient temperature of silicon single crystal technology lower, the scope of adaptation is wider.Along with the development of technology, commercially also there is a kind of video presenter at present, video presenter is also known as article showing platform, when it is connected on projector and televisor, just data, teaching materials, material object, lantern slide etc. clearly can be displayed, be one of indispensable teaching equipment of multi-media classroom.The video showing platform that one Daepori is logical comprises three parts: camera, light source and table top, also have a series of interface at the show stand back side, and some show stands towards high-end market also comprise the annexes such as infrared remote controller, computer picture capture adapter, LCD monitor.Video showing platform can be applied in each course teaching: literal arts class can various resources material, and the various books space of a whole page is used in teaching, and be directly placed in show stand table top, by the application of light, the adjustment of enlarging function, just can clearly show; Chemistry, physics subject directly can carry out some experiments on show stand, allow each student's clear view; Biological, medical science subject can observe enlarged image in kind by the adapted (microscope is first-class) of show stand camera lens.Support the use with output, input equipments such as multimedia projector, large screen back projection TV, general television set, LCD monitor, video recorder, VCD, DVD player, microphones, video showing platform has purposes widely in information technology teaching again.Teacher only just conveniently need can carry out document display by dragging with hand up and down about document.But existing video showing platform inconvenient operation, the horizontal strut part of drive head unit is easily sagging or upwarp, and structure is still comparatively complicated.
Summary of the invention
In view of the above-mentioned problems in the prior art, fundamental purpose of the present invention is to address the deficiencies of the prior art, and provides a kind of teaching distance type video showing platform, its structure is simple, easy to use, has better imaging effect, and can Remote, make it the scope of application wider.
The technical solution used in the present invention is as follows:
Distance type video showing platform is used in a kind of teaching, comprises the base with backlight, and base is provided with LCD video monitor instrument and is built-in with the control desk of rechargable power supplies, and LCD video monitor instrument is connected with control desk; Control desk is provided with infrared receiving device, and infrared receiving device is connected with Infrared remote controller; Control desk top is fixed with can the desk lamp neck of torsional bending, and desk lamp neck is fixed with head by support, and the end of head is provided with CCD camera lens; The both sides of control desk are also provided with the light compensating lamp with desk lamp neck.
Further, control desk is provided with front panel, and front panel is provided with power button and at least one function key.
Further, under using state, the CCD camera lens of head end is towards backlight.
Further, the weight of base is greater than the weight sum of head and light compensating lamp.
Further, the bottommost of base is provided with for anti-skidding non-slipping block.
In sum, compared with prior art, the invention has the beneficial effects as follows:
Present invention employs desk lamp neck, instead of complicated physical construction with desk lamp neck and reach flexible object, make the present invention more simple compared to other like product structures; The employing of CCD camera lens, also makes the present invention be provided with better imaging effect; And the present invention also built-in rechargable power supplies and infrared receiving device, when imparting knowledge to students, can Remote, just need not connect very long power lead, make it the scope of application more extensively, this is very easy to the use of teaching.
Accompanying drawing explanation
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation on controller front panel of the present invention.
Embodiment
All features disclosed in this instructions, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
As shown in Figure 1: distance type video showing platform is used in the one teaching of the present embodiment, comprise the base 1 with backlight 2, base 1 is provided with LCD video monitor instrument 12 and is built-in with the control desk 3 of rechargable power supplies, LCD video monitor instrument 12 is arranged at the side of control desk 3, and LCD video monitor instrument 12 is connected with control desk 3; Control desk 3 is provided with front panel and rear panel, and front panel is provided with power button 10 with at least one function key 11(for control operation, the work as CCD camera lens 6), it is two rows that function key 11 be arranged in parallel, and the both sides of front panel are also provided with USB interface 9; On control desk 3, the front end of front panel is provided with infrared receiving device 13, infrared receiving device 13 comprises the infrared remote receiver that is arranged at control desk 3 inside and the shell 15 for encapsulating, the position that the shell of control desk 3 is corresponding with infrared remote receiver is provided with infrared receiver hole 14, infrared receiving device 13 is connected with Infrared remote controller, for the work of this equipment of Remote; Rear panel is also provided with the power interface for charging; Control desk 3 top is fixed with can the desk lamp neck 4 of torsional bending, and desk lamp neck 4 is fixed with head 5 by support 8, and under using state, the CCD camera lens 6 of head 5 end is parallel with backlight 2 towards backlight 2, CCD camera lens; The end of head 5 is provided with CCD camera lens 6; The both sides of control desk 3 are also provided with the light compensating lamp 7 with desk lamp neck 4, and what adopt in the present embodiment is LED light supplement lamp, and it has optical efficiency high-low voltage, volume is little, the life-span is long, fast response time, shock resistance strong, the characteristics such as energy-saving and environmental protection; Can more firmly place to make this device, in base 1, add counterweight iron block in the present embodiment, make the weight of base 1 be greater than the weight sum of head 5 and light compensating lamp 7, simultaneously, be provided with for anti-skidding non-slipping block at the bottommost of base 1 again, this non-slipping block adopts the rubber blanket with fold.
