The utility model discloses an electronic interactive whiteboard. The electronic interactive whiteboard comprises a board body used for writing and projecting, a sensing camera system, a light emitting unit, a projecting system and a computer control system, wherein frames are arranged on the edges of the board body, the sensing camera system comprises at least two electronic cameras which are respectively installed in the frames in an embedded mode, the lenses of the electronic cameras receive light transmitted along the board face, the light emitting unit is an electronic pointer provided with an infrared emission light source, the projecting system is arranged in front of the board body, and the computer control system is connected with the electronic cameras and the projecting system. The method that corresponding position data are obtained by means of calculation through detection of the position, blocked by infrared, of the board face is changed, the method that infrared emitted by the electronic pointer is detected to obtain the corresponding position data by means of calculation is used, the condition that a large number of infrared LEDs are arranged on the frames can be avoided, the whole system is simpler in structure, and manufacturing cost is relatively low.
Description
Technical field
The utility model relates to a kind of board of education, especially a kind of electronic interactive board of education.
Background technology
Along with developing rapidly of infotech, the content of courses also realizes information-based gradually, and traditional blackboard can not satisfy the requirement of information-based teaching.In recent years along with development of electronic technology, touch control and be widely used mobile phone, in the panel computer, for the operation of electronic equipment has brought very big conveniency and better operating experience, also be very suitable for the electronic interactive blank and touch control, can conveniently operate and show, but the different and electronic equipment of touch control that is used for the electronic interactive blank, be the touch control of adopting optical profile type, its principle is that the whole plate face at the electronic interactive blank is uniformly distributed with infrared ray, at least one side at the electronic interactive blank is provided with a plurality of infrared cameras, as object, as finger or teacher's pointer when the plate face, cause local infrared ray to be blocked, thereby obtain corresponding position data after being detected the row operation of going forward side by side by infrared camera.Owing to need be uniformly distributed with infrared ray at whole plate face, therefore need lay infrared light-emitting diode at frame, its cost of manufacture is higher relatively.
Summary of the invention
The purpose of this utility model provides a kind of electronic interactive blank, can remove from and lay infrared light-emitting diode in frame, and cost of manufacture is relatively low.
The utility model is to realize above-mentioned purpose like this:
The electronic interactive blank comprises that conduct is write and the plate body of projection, and the plate body edge is provided with frame; The induction camera system is arranged, and it comprises at least two electro-photographic heads the induction camera system, and the electro-photographic head is flush-mounted in respectively in the frame, and the camera lens of electro-photographic head receives the light that transmits along the plate face; Luminescence unit is arranged, for having the electronic teacher pointer of infrared emission light source; Optical projection system is arranged, be arranged at plate body the place ahead; Computer control system is arranged, and it is connected with electro-photographic head and optical projection system.
Wherein, described infrared emission light source is arranged at the end of electronic teacher pointer.
Wherein, described electronic teacher pointer is provided with switch and the control circuit for the control infrared emission light source.
Wherein, the induction camera system comprises four, is arranged at the upper side frame of plate body.
Wherein, also be provided with infrared emission light source along frame, it is formed by wiring board and along the equally distributed infrared light-emitting diode of wiring board, and luminous zone the place ahead is provided with diffusion sheet.
The beneficial effects of the utility model are: change the mode that the position calculation that in the past was blocked by the flushing outside line of check-out console obtains corresponding position data, use the corresponding position data of infrared ray calculating acquisition that the detected electrons teacher's pointer sends instead, can remove from frame a large amount of infrared light-emitting diodes are set, the total system structure is simpler, and cost of manufacture is relatively low.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of plate body;
Fig. 3 is the structural representation of frame.
Embodiment
With reference to Fig. 1 and Fig. 2, the electronic interactive blank comprises that conduct is write and the plate body 1 of projection, and plate body 1 edge is provided with frame 2; The induction camera system is arranged, and it comprises at least two electro-photographic heads 3 the induction camera system, and electro-photographic head 3 is flush-mounted in respectively in the frame 2, and the camera lens of electro-photographic head 3 receives the light that transmits along the plate face; Luminescence unit is arranged, for having the electronic teacher pointer of infrared emission light source; Optical projection system is arranged, be arranged at plate body 1 the place ahead; Computer control system is arranged, and it is connected with electro-photographic head 3 and optical projection system.Change the mode that the position calculation that in the past was blocked by the flushing outside line of check-out console obtains corresponding position data, use the infrared ray that the detected electrons teacher's pointer sends instead, after infrared ray is detected by electro-photographic head 3, the machine control system is calculated the back and is obtained corresponding position data as calculated, controlling cursor then operates, operate accordingly and need content displayed then to project image onto on the plate body 1 by optical projection system, can remove from sheet frame so a large amount of infrared light-emitting diodes are set, the total system structure is simpler, and cost of manufacture is relatively low.
Wherein, infrared emission light source is arranged at the end of electronic teacher pointer, as long as the end of electronic teacher pointer approaches or the contact plate face, make infrared ray that its end sends to be detected by electro-photographic head 3 and just can obtain corresponding position data by the computing of computer control system and operate to control cursor etc. during use.
For making things convenient for the user to start interactive operation as required when operating, described electronic teacher pointer is provided with switch and the control circuit for the control infrared emission light source.As long as Push switch just can be controlled the whether luminous of infrared emission light source by control circuit, thereby realize opening or closing interactive operation.
Be the purpose that satisfies large-scale electronic interactive blank and realize multi-point touch, the induction camera system comprises four, is arranged at the upper side frame of plate body 1.
Certainly, the design is except using the infrared emission light source of teacher's pointer as the induction use, can also be in conjunction with existing design, also be provided with infrared emission light source 6 along frame 2, it is formed by wiring board and along the equally distributed infrared light-emitting diode 4 of wiring board, luminous zone the place ahead is provided with diffusion sheet 5, with reference to Fig. 3.The user just is free to switch so, to satisfy different user demands.
