Problems solved by technology

The window system is mainly aimed at pedestrians. When the position of the window cannot be touched or the flow of people is large, it is not convenient for people to touch the screen to obtain product information, and it is not convenient for people to quickly access to the modern fast-paced life. Convenient access to product information and online purchases

Embodiment 1

[0032] Such as Figure 1-2 As shown, a window projection system using visible light communication technology includes a streaming media database, a playback control module, a visible light information drive module, an LED projector, dimming glass, and a client; the streaming media database and the playback control module connected, the playback control module is connected to the LED projector.

[0033] The streaming media database is a multimedia server, which stores the commodity advertisement and the commodity purchase link address matched with the commodity advertisement in the multimedia server;

[0034] The LED projector is an LED light source ultra-short-focus projector, and the transmittance of the LED projector is controlled between 0.23:1 and 0.3:1, which can ensure that the distance between 40 cm and 60 cm from the window glass is that It can project a picture over 150 inches, which not only ensures the projection display effect but also minimizes the requirements f...

Embodiment 2

[0047] This embodiment is basically the same as Embodiment 1, except that: when the LED projector leaves the factory, the manufacturer generally sets its brightness to several controllable levels for users to adjust the brightness of the LED projector according to the intensity of ambient light. Projector brightness level, this function can be controlled through the serial port.

[0048] The display objects of the window projection system are mainly outdoor pedestrians. It is necessary to properly increase the brightness level of the projector to achieve the best display effect during the day when the light is strong, and automatically reduce the brightness level after nightfall to ensure the playback effect as much as possible. To save electricity. For this, as Figure 4-5 As shown, the playback control module includes a central processing unit (referred to as: CPU) and a Bluetooth module connected to the CPU, an RS232 serial port, a WiFi module, a storage module and a light...

Abstract

The invention discloses a show window projection system using visible light communication technology. The show window projection system comprises a streaming media database for storing commodity advertisements and commodity data information; dimming glass installed on a show window; an LED projector for projecting the commodity advertisements on the dimming glass; a visible light information driving module connected to the LED projector for controlling an LED lamp to transmit visible light information; a play control module connected to the LED projector to push the commodity advertisements tothe LED projector, connected to the visible light information driving module to push the commodity data information to the visible light information driving module and connected to the dimming glassfor controlling turning on and off of a dimming glass power supply. The system modulates the commodity-related information into the visible light frequency band, and pedestrians can interact with theshow window through a client, so that the system can effectively improve the interactive shopping experience and the application value of the show window in commercial activities.

Description

technical field [0001] The present invention relates to a window projection system, in particular to a window projection system using visible light communication technology. Background technique [0002] Stores can display and advertise their products to the outside world through the window, thereby attracting pedestrians to enter the store for shopping. Ordinary shop windows are just posting posters and displaying some static products at the same time, and better ones are to display dynamic information of products through motor transmission, sound and light control, etc. However, in the era when online shopping is becoming more and more popular, the traditional display windows can no longer effectively attract consumers to shop, let alone satisfy people's needs for interactive shopping experience. Although there are also new types of display windows in the market that send QR codes through LED large screens and other devices to guide people to scan the codes to pay attenti...
