The PLC controller is a CPU224XP controller.

The writing pen is an electronic pointer fixed at the other end of the electronic whiteboard pen.

The working process is as follows: firstly, an electrifying signal is transmitted to the projector 8 through the writing pen 19, after the projector 8 is electrified, courseware content is opened through the display 16, and the projector 8 projects courseware on the interactive electronic whiteboard 5;

the first condition is as follows: only staff is in the courseware, teaching contents are written among the staff through the writing pen 19, when the current page of the interactive electronic whiteboard 5 is full, the writing pen 19 clicks a storage button on the interactive electronic whiteboard 5, and the teaching contents in the current page are transmitted to the second storage module 13; when the content of the previous page needs to be turned over, the page turning signal is transmitted to the PLC 18 through a return button on the writing pen 19, the PLC 18 transmits the conversion signal to the data processing module 15, and the data processing module 15 calls the data in the second storage module 13 to be displayed on the interactive electronic whiteboard 5; corresponding pronunciation teaching is carried out in the teaching process, a teacher can show pronunciation skills for students while writing notes, and at the moment, the sound is captured by the recording module 14 in the interactive electronic whiteboard 5, so that audio signals are stored in the second storage module 13; when a writing pen 19 is used for clicking notes written on a current page, a click signal is firstly transmitted to the PLC 18, then the PLC 18 transmits a conversion signal to the data processing module 15, the data processing module 15 calls audio information in the second storage module 13 to the broadcasting module 17, and the broadcasting module 17 broadcasts audio corresponding to the notes;

case two: when the staff and teaching contents are projected on the interactive electronic whiteboard 5, the courseware contents are expanded and annotated during the explanation period, and classroom notes are annotated near the corresponding courseware position on the interactive electronic whiteboard 5 by using the writing pen 19; on one hand, the interactive electronic whiteboard 5 stores the classroom remark content into the second storage module 13 according to the storage button; on the other hand, the image recognition module 11 in the projector 8 automatically recognizes the content on the interactive electronic whiteboard 5, including the original courseware and the newly added remarks, and transmits the content information to the first storage module 12; at this time, the display 16 is operated, the information stored in the first storage module 12 and the second storage module 13 is called through the PLC 18, and then the information is merged through the data processing module 15 to form an accurate classroom note which is stored in the first storage module 12 (or the second storage module 13); the classroom notes can also be turned out by the writing pen 19 if required for the classroom.

Case three: for teachers with different heights, ascending (descending) signals can be transmitted to the PLC controller 18 by operating the writing pen 19, the PLC controller 18 transmits the converted signals to the servo motor 3, and the screw rod 9 is driven to rotate by starting the servo motor 3, so that the sliding block 4 is driven to ascend (descend), and the interactive electronic whiteboard 5 is finally ascended (descend); when the interactive electronic whiteboard 5 performs ascending (descending) action, the telescopic cylinder 7 also receives a conversion signal of the PLC 18 and synchronously acts with the servo motor 3, and the telescopic cylinder 7 drives the projector 8 to perform ascending (descending) action synchronously, so that the projection content is ensured to be on the interactive electronic whiteboard 5 at any time; when the interactive electronic whiteboard 5 rises (descends) to the top (bottom) of the screw, the second limit switch 10 at the top (or the first limit switch 6 at the bottom) is triggered, at this time, the second limit switch 10 at the top (or the first limit switch 6 at the bottom) transmits a trigger signal to the PLC controller 18, then the PLC controller 18 converts the signal and sends a stop signal to the servo motor 3, and finally the servo motor 3 controls the interactive electronic whiteboard 5 to stop rising (descending); the projection angle of the projector 8 is fixed by manually adjusting the angle adjuster 801.

In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description of the present invention, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
