Detailed ways

As shown in Figure 1-12, a computer-based library intelligent reading system includes a central server unit installed in the library and several situational reading devices for displaying electronic book materials stored in the central server unit. The central server unit is generally composed of a plurality of servers, which store electronic versions of e-books and related audio-visual materials such as sounds, pictures, and videos. The video image data can be 2D video, 3D video, etc. When viewing, just wear 3D glasses to watch. There is also built-in reading platform software in the central server unit, and the reading platform software is equipped with a mobile phone APP. Users can use mobile phones to complete registration, login, reading and other operations. The present invention adopts the way of projection to perform multi-angle three-dimensional playback and display of image data, and the projector 6 is mounted in the situational reading device.

The system is used as follows:

a. The built-in reading platform software of the central server unit, users log in to the reading platform software through the mobile phone APP of the reading platform software, and complete registration, login, real-name authentication and other matters.

b. The reading platform software automatically assigns situational reading devices to users according to the idleness of each situational reading device in the library; specifically: each situational reading device corresponds to a reading position number, reading position No. 1, reading position No. 2, etc. , the reading platform software randomly assigns an idle situational reading device to the user. Of course, extended functions can also be added, and the user can select the reading position by himself.

c. The user goes to the assigned situational reading device and operates through the mobile phone terminal of the reading platform software to control the startup of the situational reading device; the situational reading device prepares for reading, for example: under the projection screen, the startup of the projector, etc.

d. The user uses the mobile terminal of the reading platform software to operate, retrieves the electronic book image data stored in the central server, and plays it through the contextual reading device.

A huge difference between the situational reading device of the present invention and the traditional projection method is that it adopts multi-angle three-dimensional surround projection, and compared with the traditional single-curtain projection, the display effect is better, and the readers are immersed in the scene. And abandon the traditional wall-mounted projection, and use the ceiling projection. Specifically, as shown in FIG. 1 , each of the situational reading devices includes a ceiling-type reading bin 1 and a rotating reading platform 2 correspondingly arranged below the ceiling-type reading bin 1 . It is the reading compartment installed on the top, which does not occupy the ground space in the rolled state, and provides the possibility for the installation and adaptation of other equipment, as well as the flexible choice of the reader's reading position. Of course, the present invention can also be used in combination with the rotating reading platform 2, so that readers can rotate in the circumferential direction, and cooperate with the circumferential stereoscopic projection to create a realistic visual experience.

The rotating reading platform 2 is used as a reader's carrying equipment, and functional equipment such as seats and reading tables can be carried synchronously on it. The rotating reading platform 2 can adopt a commercially available conventional rotating platform 2, and can also be used as shown in Figures 10 and 11. As shown, the rotating reading platform 2 includes a base 46 and a rotating disk 47 disposed above the base 46, the base 46 serves as an installation base, and the rotating disk 47 serves as a rotating component. Because the rotating reading platform 2 not only needs to bear the weight of the reader, but also needs to bear the weight of functional parts such as seats and reading tables, so its stability and smoothness face a huge test. Therefore, the present invention optimizes and improves on the basis of the traditional rotary platform.

Specifically, the center of the top of the base 46 is provided with a mounting groove, and a rotating motor 48 is arranged in the mounting groove, the output end of the rotating motor 48 faces upward, and is fixedly connected to the bottom surface of the rotating disk 47, so as to realize For driving the rotating disk 47 , the rotating motor 48 is controlled by a platform controller 52 . That is to say, the base 46 is further provided with a control slot, and the control slot is provided with a platform controller 52, and the platform controller 52 is directly connected to the central server unit by communication.

For the accuracy and stability of positioning, it is better to set a shoulder or a ring groove on the upper surface of the base 46, and directly locate and install the plane bearing 49 in the shoulder or ring groove. The edge of the rotating disk 47 is bent downward to form an edge protection part 50. On the one hand, the edge protection part 50 plays a protective role of surrounding enclosure, and on the other hand, it also serves as a gap between the rotating disk 47 and the base 46. Another connecting part, as shown in FIG. 10 , is a platform bearing 51 disposed between the edge guard 50 and the peripheral surface of the base 46 .

The rotary reading platform 2 of the present invention has a compact and stable structure, smooth and smooth rotation, and has a longer service life than the traditional rotary platform. Specifically, during use, the rotating motor 48 starts to drive the rotating disk 47 to rotate, and the user stands on the rotating disk 47 to be rotated by the rotating disk 47 . Compared with the traditional rotary platform, the weight of the present invention is mainly borne by the plane bearing 49, which improves the force condition of the output end of the rotary motor 48, and the platform bearing 51 can also disperse the stress of some parts, so that the stress of each part is evenly distributed. During the rotation process of the rotary disk 47, its stability and smoothness are greatly improved, mechanical failure and damage are not easy to occur, and the service life of the present invention is improved.
