Accompanying drawing explanation

This utility model will illustrate by example and with reference to the appended drawing, wherein:

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the structural representation on this utility model controller front panel.

Detailed description of the invention

All features disclosed in this specification, 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: the teaching of the present embodiment distance type video showing platform, including the base 1 with backlight 2, base 1 is provided with LCD video monitor instrument 12 and is built-in with the control station 3 of rechargable power supplies, LCD video monitor instrument 12 is arranged at the side of control station 3, and LCD video monitor instrument 12 is connected with control station 3；Control station 3 is provided with front panel and rear board, and front panel is provided with power button 10 and at least one function key 11(for controlling operation, such as the work of CMOS camera lens 6), it is two rows that function key 11 be arranged in parallel, and the both sides of front panel are additionally provided with USB interface 9；On control station 3, the front end of front panel is provided with infrared receiving device 13, infrared receiving device 13 includes being arranged at the infrared remote receiver within control station 3 and the shell 15 for encapsulating, the position that the shell of control station 3 is corresponding with infrared remote receiver is provided with infrared receiver hole 14, infrared receiving device 13 is connected to IR remote controller, for the work of this equipment of Remote；Rear board is additionally provided with the power interface for charging；Control station 3 top be fixed with can the desk lamp neck 4 of torsional bending, desk lamp neck 4 is fixed with head 5 by support 8, and under use state, the CMOS camera lens 6 of head 5 end is parallel with backlight 2 towards backlight 2, CMOS camera lens；The end of head 5 is provided with CMOS camera lens 6；The both sides of control station 3 are additionally 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 the characteristics such as light efficiency high-low voltage, volume is little, life-span length, fast response time, shock resistance strong, energy-saving and environmental protection；In order to make this device more securely to place, the present embodiment adds counterweight iron block in base 1 so that the weight of base 1 is more than the weight sum of head 5 and light compensating lamp 7, simultaneously, being 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.

More high-end equipment, CCD camera lens can be adopted, the semi-conducting material of its a kind of ISO of use of CCD is made, light can be transformed into electric charge, converting digital signal to by analog-digital converter chip, digital signal is preserved by the flash memory of camera internal or built-in hard disk card after overcompression, thus easily data can be transferred to computer, and by means of the process means of computer, revise image with imagination as required.CCD is made up of many photosensitive units, generally in units of mega pixel.When CCD surface is subject to light irradiation, electric charge can be reflected on assembly by each photosensitive unit, and signal produced by all of photosensitive unit is added together, and just constitutes the picture that a width is complete.

Compared to CCD camera lens, the topmost advantage of CCD camera lens compared by the CMOS camera lens that this utility model adopts is exactly very power saving.Cmos circuit, almost without static electric quantity consumption, only just has the consumption of electricity when circuit ON.This power consumption allowing for CMOS only has about the 1/3 of common CCD.Current CMOS subject matter is when processing fast-changing image, and owing to curent change is excessively frequent and overheated, dark current (annotates see after literary composition) that to suppress well just less problematic, if suppress there is assorted point in bad being easy for.The view data scan method of CMOS and CCD has very big difference.The such as resolution of a digital camera is 3,000,000 pixels, then ccd sensor is continuously 3,000,000 electric charges of scanning, and in the end signal could be amplified after having scanned by an electric charge.And each pixel of cmos sensor has one to be the amplifier of electronic signal by charge conversion.Therefore, cmos sensor can carry out signal amplification in each pixel basis, adopts and can carry out rapid data scanning in this way.

LCD video monitor instrument has the advantage that resolution is higher, and display quality is higher, and power consumption is low, it does not have electromagnetic radiation, and effective area reaches, and range of application is also wider.

From such scheme it can be seen that this utility model have employed desk lamp neck, instead of, with desk lamp neck, the purpose that complicated frame for movement reaches to stretch so that this utility model is more simple compared to other like product structures；And the also built-in rechargable power supplies of this utility model, when teaching, very long line just need not be connect, this is very easy to the use of teaching.

Description of the present utility model and application are illustrative, are not wishing to limit in the above-described embodiments scope of the present utility model.The deformation of embodiments disclosed herein and change are possible, for those skilled in the art embodiment replace and the various parts of equivalence are known.It should be appreciated by the person skilled in the art that when without departing from spirit of the present utility model or substitutive characteristics, this utility model can otherwise, structure, layout, ratio, and realize with other elements, material and parts.
