Abstract
Description
Technical Field
[0001] This utility model relates to the field of interactive technology, specifically to a smart blackboard. Background Technology
[0002] In education, training, and office settings, smart blackboards are commonly used to achieve better interaction. Current smart blackboards consist of a display screen and blackboards positioned on either side of it. The display screen shows electronic content, such as PowerPoint presentations and videos, while the blackboards display handwritten notes from the instructor using chalk or other writing materials. The handwritten notes cannot be synchronized to the centrally located display screen for viewing by people in different positions, nor can they be saved as electronic files for later review.
[0003] To solve the above problems, infrared touch frames or optical touch frames are usually added to the blackboard to capture the position of the writing and send the coordinates to the computer. However, these frame-type touch products are easily covered by chalk dust, which affects the capture of the writing. Therefore, they need to be wiped and maintained frequently. Summary of the Invention
[0004] In view of this, the present invention provides a smart blackboard to solve the above-mentioned technical problems.
[0005] To achieve the above technical objectives, this utility model provides a smart blackboard, including a display screen, two blackboards, and two touch acquisition devices;
[0006] One side of the blackboard is fixedly connected to each side of the display screen, and a touch acquisition device is fixedly connected to the other side of each blackboard;
[0007] Both touch acquisition devices are communicatively connected to the display screen, and the two touch acquisition devices are communicatively connected via a synchronization line.
[0008] Furthermore, the two sides of the display screen are respectively fixedly connected to one side of the blackboard by buckles and pins, and the top sides of the two blackboards are aligned with the top side of the display screen.
[0009] Furthermore, both the pull tab and the latch are located on the back of the blackboard and the display screen.
[0010] Furthermore, each of the blackboards is fixedly connected to a touch acquisition device on the other side by screws.
[0011] Furthermore, the touch acquisition device is equipped with a hub box, which houses the power cord, the synchronization cable, and the USB cable.
[0012] Furthermore, the touch acquisition device is communicatively connected to the display screen via the USB cable.
[0013] Furthermore, the touch acquisition device includes a long strip mounting bracket adapted to the blackboard, with cameras at both ends of the mounting bracket and a light source between the two cameras.
[0014] Furthermore, the light source is a plurality of infrared LED beads spaced apart on the mounting bracket.
[0015] Compared with the prior art, this utility model has the following advantages due to the adoption of the above technical solution:
[0016] Because this invention sets the touch acquisition device on the side of the blackboard, it not only effectively avoids the problem of interference from dust covering the touch object or writing object, but also places the touch acquisition device on the other side separated from the display screen, so that there is no interference between the size or shape of the display screen and the size or shape of the touch acquisition device. In other words, the blackboard with integrated touch acquisition device can be adapted to more types of display screens, and even adapt to any type or size of display screen.
[0017] Meanwhile, in existing technologies, the display screen is usually a flat screen. Placing the touch collection device on the side of the blackboard, which is separated from the display screen, avoids the unevenness of the top of the smart blackboard compared to placing it on the top of the blackboard. This makes the overall appearance simpler, more elegant, and more beautiful, effectively improving the sense of technology and user experience. Furthermore, placing the touch collection device on the side of the blackboard, which is separated from the display screen, also avoids the problem of capture interference caused by reflections from the bottom floor compared to placing the touch collection device on the top of the blackboard.
[0018] In addition, by connecting the two touch acquisition devices via a synchronization line, data synchronization between the two touch acquisition devices can be achieved, avoiding mutual interference when the two touch acquisition devices are working simultaneously.
[0019] This invention is easy to install, simple to maintain, and low in cost, and can be widely used in the field of interactive technology. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.
[0023] like Figure 1-2 As shown, this utility model embodiment provides a smart blackboard, including a display screen 1, two blackboards 2 and two touch acquisition devices 3;
[0024] A blackboard 2 is fixedly connected to one side of each side of the display screen 1, and a touch acquisition device 3 is fixedly connected to the other side of each blackboard 2;
[0025] Both touch acquisition devices 3 are connected to the display screen 1, and the two touch acquisition devices 3 are connected to each other via a synchronization line 4.
[0026] When in use, the touch acquisition device 3 collects the touch objects or writing objects on the blackboard 2 in real time and displays the collected data synchronously through the display screen 1.
[0027] Obviously, by setting the touch acquisition device 3 on the side of the blackboard 2, not only is the problem of interference from dust covering the touch object or writing object captured effectively avoided, but also by setting the touch acquisition device 3 on the other side separated from the display screen 1, so that there is no interference between the size or shape of the display screen 1 and the size or shape of the touch acquisition device 3. That is, the blackboard 2 with the integrated touch acquisition device 3 can be adapted to more types of display screens 1, and can even be adapted to any type or size of display screen 1.
[0028] Meanwhile, in the existing technology, the display screen 1 is usually a flat screen. Placing the touch acquisition device 3 on the side of the blackboard 2, which is separated from the display screen 1, can avoid the unevenness of the top of the smart blackboard compared to placing it on the top of the blackboard 2. This makes the overall appearance simpler, more elegant and beautiful, and effectively improves the sense of technology and user experience. In addition, placing the touch acquisition device 3 on the side of the blackboard 2, which is separated from the display screen 1, also avoids the problem of capture interference caused by the reflection of the bottom floor compared to placing the touch acquisition device 3 on the top of the blackboard 2.
[0029] In addition, by connecting the two touch acquisition devices 3 via the synchronization line 4, data synchronization between the two touch acquisition devices 3 can be achieved, avoiding mutual interference when the two touch acquisition devices 3 work at the same time.
[0030] In some embodiments, the two sides of the display screen 1 are respectively fixedly connected to one side of a blackboard 2 by means of a buckle and a pin, and the top sides of the two blackboards 2 are aligned with the top side of the display screen 1.
[0031] It should be noted that both the pull tabs and latches are located on the back of the blackboard 2 and the display screen 1.
[0032] In some embodiments, a touch acquisition device 3 is fixedly connected to the other side of each blackboard 2 by screws.
[0033] In some embodiments, the touch acquisition device 3 is equipped with a hub box 5, which houses the power cord, synchronization cable 4 and USB cable. The touch acquisition device 3 communicates with the display screen 1 via the USB cable.
[0034] In some embodiments, the touch acquisition device 3 includes a long strip mounting bracket adapted to the blackboard 2, with cameras at both ends of the mounting bracket and a light source between the two cameras. The light source can be a number of infrared LEDs spaced apart on the mounting bracket.
