Building simulation system based on Internet of Things

Abstract

The invention relates to the field of building simulation systems, and particularly relates to a building simulation system based on Internet of Things. The system comprises a sand table main body, a storage frame is fixedly connected to the outer side of the sand table main body, a storage groove is formed in the storage frame, a projection frame is slidably connected to the interior of the storage groove, a group of projection lamps are fixedly connected in the projection frame, and a driving mechanism is arranged in the sand table body and located below the sand table body. Through rotation of a threaded rod of a lifting mechanism, a limiting plate can be driven to rotate in a rotating groove, and through transmission of a driving gear plate and a driven gear plate, a telescopic rotating plate can rotate in a lifting sliding groove so that the projection frame rotates on the outer side of the sand table main body and can continuously rotate in the building simulation projection process; and finally, multi-angle display of the simulated building is realized, and the display effect of the simulated building is improved.

Description

technical field [0001] The invention relates to the field of building simulation systems, in particular to a building simulation system based on the Internet of Things. Background technique [0002] The building simulation system is a kind of holographic projection of the building on the electronic sand table according to a certain proportion by using the projection lamp, so that the dynamic simulation display of the building can be carried out. Usually, the projection lamp is fixed in the projection frame, and the projection frame is directly fixed. Outside the main body of the sand table. [0003] However, if the projection frame is directly fixed on the outside of the sand table without any protection, even when the projection frame is not in use, it will still be hit by foreign objects, which will cause damage to the projection frame, and the position of the projection frame cannot be fixed. Make the projected virtual building rotate, so that it is impossible to observe...

Problems solved by technology

[0003] However, if the projection frame is directly fixed on the outside of the sand table without any protection, even when the projection frame is not in use, it will still be hit by foreign objects, which will cause damage to the projection frame, and the position of the projection frame cannot be fixed. Make the projected virtual building rotate, so that it is impossible to observe the building from multiple angles. Only by walking around the sand table, the observer can see the situation of the simulated building at all angles, and the projection frame is often dusty during use. A large amount of accumulation, and during the visit, because the outer part of the projection frame is not protected by a sealed structure, water containers such as water cups are often dumped, causing water stains to enter the projection frame and damage the projection lamp
