Intelligently controllable fog screen projection system

Abstract

The present invention discloses an intelligently controllable fog screen projection system. The system comprises a fog screen generation module, a projection module, a control module, invisible light sources and an image acquisition device, wherein the fog screen generation module comprises a fog generation unit, a fog guide unit, a water filtering unit, a fog outlet and a side wall; the fog generation unit comprises a water tank and an ultrasonic wave integrated sprayer plate; the water filtering unit comprises a fog generation water fender; the fog guide unit comprises a fog guide fan, ventilation wall fans, a fog guide pipe and air guide pipes, and also comprises air velocity transducers and power adjusting modules, wherein outside air velocity information is detected by the air velocity transducers and sent to the control module, and the control module processes the air velocity data, controls rotating angles of the fog guide pipe and the air guide pipe according to the processed data, and controls the power adjusting modules to adjust output power of the fog guide fan and the ventilation wall fan. Influence factors of air velocity on fog screens are effectively compensated, the fog screen display effect is raised, and the intelligently controllable fog screen projection system is suitable for usage outdoors.

Description

technical field [0001] The invention belongs to the field of projectors, and in particular relates to an intelligent and controllable fog screen projection system. Background technique [0002] The projection screens in existing projection systems mostly use hanging screens, bracket screens, folding screens, floor screen frame screens, etc., which need to be installed and erected during use, requiring a certain amount of space. Neither the hard curtain nor the soft curtain is easy to clean. [0003] Most of the projection systems disclosed in the prior art use ordinary projectors, which have long projection distances, take up a lot of space, and need to place the projector and the fog screen generating device separately, so the application occasions are limited. At the same time, the fog screens disclosed in the prior art cannot realize free-hand human-computer interaction, and can only realize the function of a single display screen. In addition, the fog screen generating...
