Embodiment Construction

[0017] Such as Figures 1 to 4 as shown ( image 3 Four scissor lift platforms 12 are omitted in the figure.

[0018] According to the demonstration site, a classroom needs to design and install this composite sand table demonstration device for teaching demonstration. According to teaching needs, the compound sand table demonstration device should have a desktop layout as a whole, and the table size of the sand table demonstration table is determined to be 3 meters x 5 meters, and the height should not exceed 0.6 meters.

[0019] The physical sand table should be scaled up according to the scope of the electronic map, and should not be larger than the above-mentioned size limit of 1.35m x 1.55m x 0.25m. In order to enhance the demonstration effect, the physical sand table is made of plastic material, and is made by mechanical engraving and color spraying technology.

[0020] The composite sand table demonstration device includes a virtual demonstration mechanism and a sand...

Abstract

The invention provides a compound type sand table demonstration device. The compound type sand table demonstration device comprises a virtual demonstration mechanism and a sand table adjusting mechanism; the sand table adjusting mechanism comprises a support plate, several scissor type lifting platforms, several track assemblies and several first electric sliding platforms; the upper end face of the support plate is an area, where a solid sand table is placed; the first sliding rail of the track assembly and the support plate are fixed through a bolt; the second sliding rail and the upper endof the scissor type lifting platform are fixed through a bolt; the base of the first electric sliding platform and the second sliding rail of the track assembly are fixedly connected; the sliding partof the first electric sliding platform and the support plate are fixedly connected; the virtual demonstration mechanism comprises a support frame and a transparent display screen; a cavity is in thesupport frame; the upper end face of the support frame is opened; and the transparent display screen is horizontally placed at the opening position of the support frame. The compound type sand table demonstration device in the invention has the beneficial technical effects that: a multimedia interaction demonstration system, which is formed by combination of the traditional sand table and the transparent display screen covering thereon, is applied to the field that the solid sand table needs to be replaced untimely or frequently.

Description

technical field [0001] The invention belongs to the field of multimedia interactive display, and in particular relates to a composite sand table demonstration device capable of virtual and real interaction. Background technique [0002] At present, there are more and more cases of multimedia interactive display systems combining electronic display technology and traditional sand tables. The main development directions are: intelligent dynamic display sand tables composed of physical sand tables and LED lights; physical sand tables combined with dynamic projections Intelligent dynamic display sand table; traditional sand table or intelligent dynamic display sand table combined with wall-mounted display screen, multimedia interactive digital sand table, these multimedia interactive display systems have their own advantages and disadvantages in different application fields. [0003] However, at present, this type of multimedia interactive demonstration system still uses the tra...
