The barcodes 3, 3a, 3b and 3c are respectively and correspondingly arranged in the electromechanical working areas A1, A2, A3 and A4 and respectively correspond to teaching multimedia information. In the present embodiment, the barcodes 3, 3a, 3b, and 3c are two-dimensional barcodes, but the invention is not limited thereto, and may be linear barcodes.
The mobile communication device 4 includes an image capturing module 41, a processing module 42 and a playing component 43. Mobile communication device 4 is a smart phone. The memory module 2 may also be provided in the mobile communication device 4 as a memory card.
Next, please refer to fig. 1 to 5, wherein fig. 3 is a schematic diagram illustrating a barcode acquired by the mobile communication device of the present invention; FIG. 4 is a diagram illustrating a mobile communication device playing instructional multimedia information in accordance with the present invention; and, FIG. 5 is a schematic view of another embodiment of the mobile communication device of the present invention displaying multimedia information for teaching. As shown, the mobile communication device 4 is aligned with the barcode 3, and the barcode 3 is regarded as a selected barcode.
The image obtaining module 41 correspondingly obtains a barcode image V3. The processing module 42 is communicatively connected to the image obtaining module 41 and the storage module 2, so as to analyze the barcode image V3 and obtain a teaching multimedia information I3 corresponding to the barcode image V3.

Although the drawings are only schematic, the magnetic element 19 is connected to the second arm segment L2, and the magnetic element 19a is connected to the third arm segment L3, so that when the magnetic element 19 or the magnetic element 19a rotates, the other one is linked to the magnetic repulsion force due to the magnetic attraction force, and the second arm segment L2 or the third arm segment L3 moves accordingly. The magnetic elements 19, 19a may be magnetic elements such as electromagnets, permanent magnets, magnetic disks, electrically controlled magnetic disks, and the like.
As shown in fig. 8 and 9, the mobile communication device 4 aligns with the barcode 3c, and when the barcode region a5 obtains the corresponding barcode image V3c, the playing region a6 corresponds to a third housing 15, a clamp 16 and a pneumatic cylinder 17 of the electromechanical working region a4 of the actual electromechanical device 1, and plays the multimedia information I3c and the multimedia information I3c 1. The teaching multimedia information I3c indicates that the pneumatic cylinder 17 is not activated and the clamp 16 is not clamped. The teaching multimedia information I3c1 shows that the pneumatic cylinder 17 starts to operate, so the clamp 16' is clamped. The clamped clamp is designated herein as clamp 16' for distinction.
As shown in fig. 10, the image acquiring module 41 of the mobile communication device 4 acquires a barcode to obtain a barcode image V3 d. The barcode image V3d, its corresponding barcode and electromechanical working area are disposed at a bottom B of the electromechanical device 1, which cannot be shown in fig. 1 due to the angle relationship.

When the battery is correctly placed, the playing component 43 will play the teaching multimedia information I3d1, as shown in fig. 11, the teaching multimedia information I3d1 shows a schematic diagram of the current I of the battery. If the battery is placed at a wrong position, the current I cannot be generated, and the playing component 43 plays the teaching multimedia information I3d2, as shown in fig. 12. Therefore, the user can know not only the electromechanical working principle of the electromechanical working area but also whether the battery is placed correctly and whether the battery generates current or not through the teaching multimedia information I3d, I3d1 and I3d 2.
Finally, referring to fig. 13, fig. 13 is a block diagram of a teaching system for presenting the working principle of a machine according to another preferred embodiment of the present invention. As shown, a teaching system 100a for presenting principles of operation of a machine device.

The wearable display device 5a is communicatively connected to the processing module 42 and worn by the user for playing the teaching multimedia information (such as the teaching multimedia information I3, I3d in the above embodiments). Because the teaching multimedia information is played by the wearable display device 5a, the teaching multimedia information can be an augmented reality film, a mixed reality film or a virtual reality film in addition to the above-mentioned perspective view, perspective film and electrical principle, so as to increase the telepresence of the user and effectively improve the teaching effect.
