Description
[technical field]
The present invention relates to a kind of embedded PC electronic whiteboard.
[background technology]
The teaching of traditional blackboard, chalk pattern writing on the blackboard on a common blackboard can't be stored, and writes and has expired and need wipe.Along with development of science and technology, single in the past form of teaching progressively is enhanced, multi-media classroom is with by all kinds of means content of courses presentation mode, theory teaching and object teaching are combined, the multiple sense organ participation in learning of mobilizing students has promoted Teaching Quality, has improved efficiency of teaching, has enlarged teaching scale.At present, in the application of multi-media classroom, solution commonly used is based on projector, real object exhibition booth, computer etc.Such solution can easily be presented on the contents of courses such as material object, computer teaching courseware, video, audio frequency in face of the student, yet in most teaching practices, traditional " writing on the blackboard " still is the most frequently used teaching means, because by writing on the blackboard, the teacher can insert the content of courses off the cuff, can control teaching process effectively.So the mode that multi-media classroom and writing on the blackboard combine becomes the teaching pattern that many teachers like.The content of courses that multimedia courseware has brought brand-new teaching pattern and abundanter image to the student has also brought a lot of new problems simultaneously.
Still can't break away from traditional chalk during teacher's writing on the blackboard, blackboard brings bothersome dust pollution; Teacher's writing on the blackboard can't with the combination of teacher's multimedia courseware, be not easy to the student and understand; The quick broadcast of multimedia courseware, the student can't normally take down notes; The mechanical broadcast of multimedia courseware such as Word, PowerPoint, the speaker can't mark immediately, has reduced the interactive of speech.Multimedia teaching also lacks a kind of teacher's the platform of giving lessons, and is used for remedying the wide gap between traditional traditional instruction and the multimedia courseware teaching.
For this reason, the applicant Zhongshan Jiashi Opto-Electronics Technology Co., Ltd. has applied for that a patent No. is ZL200820200421.9, name is called the patent of touch-control electronic instructional device, this patent was on 07 01st, 2009 bulletin, this patent has successfully solved the problems referred to above, but, computer separates with electron plate in this patent, the electron plate that promptly is arranged in each classroom all must a supporting desktop computer or laptop computer, be provided with on electron plate and can be connected the USB interface that communicates with computer, this patent has following shortcoming:
1, computer is external, and each electron plate all will use a computer, so the cost of a whole set of teaching equipment is than higher;
2, be connected by long signal wire between computer and the electron plate, the transmission range of signal is long between computer and the electron plate like this, thereby lowers the processing speed of equipment set.
3, the teacher need walk up and down between computer and electron plate and operate, and therefore uses cumbersome.
[summary of the invention]
The present invention has overcome the deficiency of above-mentioned technology, and the embedded PC electronic whiteboard that a kind of cost is low, processing speed is high, easy to operate is provided.
For achieving the above object, the present invention has adopted following technical proposal:
A kind of embedded PC electronic whiteboard, it includes electronic panel and projector, upside and left side at electronic panel are provided with infrared transmitter, downside and right side at electronic panel are provided with infrared remote receiver, on electronic panel, also be built-in with the PC of control infrared transmitter and infrared remote receiver work, this PC is connected with the projector signal, is provided with the USB interface that leaks outside on PC.
On infrared transmitter, be provided with a plurality of infrared transmitting tubes, be provided with identical with the infrared transmitting tube number and relative one by one infrared receiving tube at infrared remote receiver.
Infrared transmitter includes:
The emission decoding scheme that is connected with PC;
With the radiating circuit that the emission decoding scheme is connected, it includes described infrared transmitting tube;
And the detection radiating circuit result whether operate as normal also will detect passes to the testing circuit of PC.
Receiver includes
The infrared transmitting tube that is used to receive radiating circuit sends the receiving circuit of signal, and it includes described infrared receiving tube;
The sample circuit that is connected with receiving circuit;
Pass to the reception decoding scheme of PC after the signal interpretation to sample circuit output.
The invention has the beneficial effects as follows:
1, PC is built-in, does not need to re-use computer, so the cost of a whole set of teaching equipment is lower;
2, infrared transmitter and the signal wire between the infrared remote receiver in PC and the electron plate is shorter, has improved the processing speed of equipment set.
3, the teacher only needs get final product at the electron plate line operate that advances, so uses more convenient.
4, carry out comprehensive lifting for traditional teaching notion, shown the revolution of mode of operation and the breakthrough of man-machine interaction especially, can effectively show different teachers' individual character and styles of teaching;
5, not only the function of traditional multi-media classroom is strengthened significantly, it has also crossed over a limit, just as a magic plate, proprietary sight is all concentrated on here, make the classroom be full of vigor, make students can come to realize each teacher's happiness, anger, grief and joy, can experience the strength that knowledge is brought to them.The most valuable is that essence of education is able to performance incisively and vividly here, reaches the boundary of " instructing in words and by deeds ";
6, outward appearance is similar to common blank, can write in the above with common soft pen, also can write in the touch-control electronic writing on the blackboard by finger, the touch-control electronic plate is linked to each other with host computer by a USB line, computer links to each other with projector again, and the content of computer can project to the touch-control electronic plate, and the operation of touch-control electronic plate and content can feed back to computer, can also be saved in floppy disk, hard disk or be transferred to network, also can directly print;
7, not only inherit traditional teaching custom and impression, make those teachers that are unfamiliar with PC operation left-hand seat easily, and the information that for students, is more readily understood and accepts to transmit from teacher, for carrying forward the modern teaching theory, provide a good carrier, for modern teaching has been expanded unlimited imagination space.
8, realize dust-free writing, arbitrarily write, long-range interchange etc.
[description of drawings]
Be described in further detail below in conjunction with accompanying drawing and embodiments of the present invention:
Fig. 1 is a synoptic diagram of the present invention;
Fig. 2 be infrared transmitter of the present invention, infrared remote receiver with PC between the block scheme that is connected;
[embodiment]
As shown in Figure 1, the present invention introduces a kind of embedded PC electronic whiteboard, it includes electronic panel 1 and projector 2, upside and left side at electronic panel 1 are provided with infrared transmitter 3, downside and right side at electronic panel 1 are provided with infrared remote receiver 4, on electronic panel 1, also be built-in with the PC 5 of control infrared transmitter 3 and infrared remote receiver 4 work, this PC 5 is connected with projector 2 signals, on PC 5, be provided with the USB interface that leaks outside, owing to be built in the electronic panel 1 with PC 5, PC is built-in like this, does not need to re-use computer, so the cost of a whole set of teaching equipment is lower; Infrared transmitter and the signal wire between the infrared remote receiver in PC and the electron plate are shorter, have improved the processing speed of equipment set.
