Abstract
The utility model discloses a teaching electronic whiteboard which is characterized by comprising a machine for a teacher, and a large-screen display screen. The machine for the teacher comprises a singlechip, a storage device and a handwriting board, wherein the handwriting board, the singlechip and the large-screen display screen are connected in sequence; and the storage device is connected with the singlechip. Compared with the prior art, the handwriting range of the teaching electronic whiteboard is limited on the handwriting board of the machine for the teacher; the cost is greatly decreased, and furthermore, the teaching electronic whiteboard can be separated from a computer and then be independently used, and is convenient to be popularized and applied in the conventional teaching.
Description
[technical field]
The utility model relates to a kind of teaching aid, particularly a kind of sub-blank of teaching consuming energy that is applicable to the language classroom.
[background technology]
Along with the continuous development of technology, obtained using widely in information interaction occasions such as education, meetings as the digitalized electron blank.Its principle of work is: electronic whiteboard is equivalent to the video screen of computing machine, the blank pen is equivalent to the mouse of computing machine, project on the blank by the demonstration of projector computing machine, straight being connected on the blank of blank operated, by resistance-type, photo-electric, sound wave type or electromagnetic type mode the operation information on the blank is turned back in the computing machine, thereby realize interactive operation.The employed electronic whiteboard of language teaching has own unique characteristics of demand: 1. classroom microteaching often, the useful area of electronic whiteboard are less than the electronic whiteboard of top class in a kindergarten's teaching such as lecture theater; 2. teacher's situation about need operate on blank is fewer, and the writing on the blackboard amount is little; 3. blank is demonstrated literal, picture, lantern slide and video playback often, does not relate to the use of complex software substantially.And every square metre of price of electronic whiteboard in the market is about 8000 yuan, needs to be equipped with simultaneously computer hardware in addition, and cost is higher, is not suitable for language teaching and uses.
[utility model content]
Technical assignment of the present utility model is at above the deficiencies in the prior art, provides a kind of cost the low sub-blank of teaching consuming energy that is applicable to the language classroom, can use handwriting pad to substitute electronic whiteboard and make input equipment, with big screen display screen as the output board face.
The technical scheme in the invention for solving the technical problem is: the sub-blank of a kind of teaching consuming energy, it is characterized in that: comprise that the teacher uses machine and big screen display screen, described teacher comprises single-chip microcomputer, storer, handwriting pad with machine, described handwriting pad, single-chip microcomputer, big screen display screen are linked in sequence, and storer is connected with single-chip microcomputer.
Above-mentioned handwriting pad also comprises the usb data interface.
Above-mentioned single-chip microcomputer also comprises wireless launcher, and big screen display screen also comprises radio receiver, and the connected mode between single-chip microcomputer and the big screen display screen is a wireless mode.
Above-mentioned wireless launcher is an infrared launcher, and radio receiver is an infrared receiving device.
Compared with prior art, the utlity model has following outstanding beneficial effect:
1, the useful area of electronic whiteboard can be selected according to the classroom area, and this big screen display screen also can be used for other purposes, a tractor serves several purposes;
2, hand-written scope is limited to the teacher and uses the machine handwriting pad, greatly reduces cost;
3, can independently use by divorced from computer, be convenient in conventional teaching, apply.
[description of drawings]
Fig. 1 is a structural representation block diagram of the present utility model.
[embodiment]
Below in conjunction with specification drawings and specific embodiments the utility model is further specified.
As shown in Figure 1, the utility model comprises that the teacher uses machine and big screen display screen, and described teacher comprises single-chip microcomputer, storer, handwriting pad with machine, and described handwriting pad, single-chip microcomputer, big screen display screen are linked in sequence, and storer is connected with single-chip microcomputer.
Described handwriting pad also comprises the usb data interface.
Described single-chip microcomputer also comprises infrared launcher, and big screen display screen also comprises infrared receiving device, and the connected mode between single-chip microcomputer and the big screen display screen is the infrared radio mode.
Operating process is as follows: utilize literal, picture, lantern slide or video in the monolithic playout storage during use, when needs mark, operate the note that both can finish on the screen with handwriting pad.The teacher is with taking wireless connections between machine and the giant-screen, and teachers' instruction is more flexible.
Need to prove; particular of the present utility model is described in detail the utility model; for a person skilled in the art, in the various conspicuous change of under the situation that does not deviate from spirit and scope of the present utility model it being carried out all within protection domain of the present utility model.
