Abstract

The invention relates to an information and advertisement projection imaging device for a subway glass shielded gate. The projection imaging device comprises a central control system, a signal sensing system, a signal transmission system, a display system, a sound system, an interaction system and a safety protection system, wherein the central control system is connected with the other six systems and provided with multiple types of safety protection interfaces. A platform area is additionally provided with a crowd density detector and an image brightness induction device. When the crowd density reaches the alarm value, a density inductor triggers the central control system, and the image of the shielded gate is switched to an evacuation tip or becomes transparent. By means of the projection imaging device, safe operation of a display system of the shielded gate can be fully guaranteed, in combination with the novelty and visual effect of the display information of the shielded gate, the information transmission rate can be increased, and economic benefits are increased.

Description

technical field [0001] The invention belongs to the technical field of subway advertisement equipment, and in particular relates to an information and advertisement projection imaging device used on a subway glass screen door. Background technique [0002] The ultra-high timeliness of the subway is the preferred means of transportation for people to travel in the city today. The subway is also known as the invisible second city because of its huge underground network and traffic. Compared with other modes of transportation, the space of the subway is relatively closed, and it is not disturbed by various external environments. The attention of waiting passengers is relatively concentrated. Combined with the regular waiting time, the rate of information attention will increase significantly. [0003] The existing information released by the subway is divided into two categories, one is static information, mainly using light boxes and stickers. The other type is dynamic inform...
