Embodiment

[0023] Such as figure 1 As shown, a schematic diagram of an information interactive elevator based on visible light communication. Including elevator car 4, traction sheave 5, traction wire rope 6. It is characterized in that it also includes an optical-wifi communication module 10, an optical-fiber Ethernet communication module 20, and a transmission shaft 3. Wherein, the optical-wifi communication module 1 is installed on the top of the elevator car 4, the optical-fiber Ethernet communication module 20 is installed on the top of the hoistway 3, and the transmission hoistway 3 is a free space for the elevator to run.

[0024] Such as figure 2 As shown, a schematic diagram of an information interactive elevator based on visible light communication. For the uplink transmission of information, the information is first converted and modulated by the optical-wifi communication module 10. Specifically, the information is first converted into a wifi signal by the wifi communicat...

Abstract

The invention discloses an information interaction type elevator based on visible light communication. The information interaction type elevator comprises an elevator car 4, a traction sheave 5, a traction steel wire rope 6, a light-wifi communication module 10, a light-fiber Ethernet communication module 20 and a transmitting shaft 3, wherein the light-wifi communication module 10 is mounted on the top of the elevator car 4; the light-fiber Ethernet communication module 20 is mounted on the top of the transmitting shaft 3; the elevator car 4 is positioned in the transmitting shaft 3; and visible light signals which are generated by the light-wifi communication module 10 and the light-fiber Ethernet communication module 20 are transmitted in the transmitting shaft 3. The information interaction type elevator based on visible light communication has the advantages that the service life is long, reliability is high, demands of passengers are considered fully, and high-quality information interactive experience is provided.

Description

technical field [0001] The present invention relates to visible light communication technology, in particular to an information interactive elevator based on visible light communication. Background technique [0002] In recent years, semiconductor lighting technology known as "green lighting" has developed rapidly. Compared with traditional lighting sources such as incandescent lamps, LEDs have the advantages of low power consumption, long life, small size, and environmental protection. At the same time, LED has the advantages of good modulation performance and high response sensitivity. The signal is loaded on the LED with a high frequency that cannot be recognized by the human eye for transmission, and then a technology that can realize the integration of lighting and communication - visible light communication (VLC). Compared with traditional infrared and wireless communication, VLC has the advantages of high transmission power, no electromagnetic interference, no need ...
