Problems solved by technology

[0002] With the development of the market and the advancement of multimedia technology, users have higher and higher requirements for acceptance experience. At present, the sand table display in the exhibition hall highlights the following shortcomings: 1. The scale of the sand table is not large enough, and the display accuracy is not high; the sand table is large and lacks details.
2. Users are not allowed to operate independently without interaction
3. The display content is single, the function is single, and the amount of information is small

Embodiment Construction

[0017] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

[0018] see Figure 1 to Figure 3 , the electronic sand table system of the present invention includes a projection sand table 1 , a touch all-in-one machine 2 , a server 3 and a LAN networking device 4 .

[0019] The projection sand table 1 shows the effect of the sand table through the super large projection screen 11; the projection sand table 1 includes a base 12 and a super large projection screen 11 which is inclined backwards and is arranged on the upper end of the base 12. Preferably, the super large projection screen 11 has an inclination of 5 °-8 °, in order to make people have a better viewing angle, the inner bottom of the base 12 is evenly arranged with a plurality of projectors 13, and the front side of the lens of each of the projectors 13 is obliquely provided with a reflector 14. Each of the projectors 13 splices a pluralit...

Abstract

The invention discloses an electronic sand table system which comprises a projection sand table, a touch and control integrated machine, a server and a local area network networking device. The projection sand table displays the sand table effect through an oversized projection screen. The touch and control integrated machine is used for achieving touch control of the playing content of the projection sand table and achieving human-computer interaction operation. The server is used for providing data information of a geographical information system (GIS) map and a closed circuit television system and displaying the data information on the oversized projection screen of the projection sand stable under the control of the touch and control integrated machine. The local area network networking device is used for connecting the projection sand table, the touch and control integrated machine and the server into one local area network and achieves fast and effective data transmission among the three. The electronic sand stable system integrates the functions of touch interaction, video playing, GIS map information inquiry, closed circuit television system checking and the like, achieves oversized screen clear display and independence interaction, saves occupied space while ensuring displaying effect, and improves expandability.

Description

technical field [0001] The invention relates to a multimedia interactive display device, in particular to an electronic sand table system. Background technique [0002] With the development of the market and the advancement of multimedia technology, users have higher and higher requirements for acceptance experience. At present, the sand table display in the exhibition hall highlights the following shortcomings: 1.
