Fog screen projection system

Abstract

The invention discloses a fog screen projection system. The system comprises a fog screen generating module, a projection module, a control module, an invisible light source and an image acquiring device, wherein the fog screen generating module comprises a fog generating unit, a fog guide unit, a water filtering unit, a fog outlet and a sidewall; the fog generating unit comprises a water tank and an ultrasonic integrating atomizing plate; the fog guide unit comprises a fog guide fan, an air wall blower, a fog guide tube and air guide tubes, wherein the air guide tubes are symmetrically distributed at two sides of the fog guide tube; the fog guide tube and the air guide tubes can be integrally rotated in the same direction; an air speed sensor connected with the control module is arranged at the outer side of the fog outlet and is used for detecting the external air speed information and sending the information to the control module; the control module can process the air speed data and control the rotating angles of the fog guide tube and the air guide tubes. According to the system, the rotating angles of a fog guide opening and air guide openings can be controlled through the controller according to the air speed information, so that the shape influence factor of the air speed on a fog screen can be effectively compensated; the fog screen display effect can be improved; the system is suitable for outdoor use.

Description

technical field [0001] The invention belongs to the field of projectors, and in particular relates to a 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 device disclosed in the prior...
