Elevator car information transmission system based on visible light communication technology

Abstract

The invention discloses an elevator car information transmission system based on the visible light communication technology. The elevator car information transmission system comprises a car communication transmission system and a car communication reception system. The care communication transmission system comprises a first microprocessor, a first single-chip microcomputer, a circuit module, a first LED visible light transmission and reception device, a controller local network bus and a multimedia communication module. The car communication reception system comprises a control box, a second microprocessor, a second single-chip microcomputer and a second LED visible light transmission and reception device. Information transmission of an elevator car is achieved by means of the system through the visible light communication technology, the manner is obviously superior to an existing non-contact type transmission manner of car information, and the elevator car information transmission system has the characteristics of being low in installation and maintenance cost, green, environment-friendly, low in power consumption, high in safety and the like.

Description

technical field [0001] The invention relates to an elevator car information transmission system, in particular to an elevator car information transmission system based on visible light communication technology. Background technique [0002] Visible light communication technology, as an emerging wireless communication technology that uses light-emitting devices to send out high-speed bright and flickering light signals that are invisible to the human eye to achieve information transmission, has the advantages of green environmental protection, no electromagnetic interference, high data transmission rate, and low power consumption. Moreover, unlike existing radio wave transmission methods, visible light communication can only receive signals where the light reaches, so it has high security performance and is not easy to leak information. [0003] The elevator car is a box-shaped space used by the elevator to transport people and materials. It generally uses a suspended accompa...

Problems solved by technology

Among them, the non-contact transmission methods of electric energy include guide rail type and floor power station type, etc., and the non-contact transmission methods of information include radio wave type and wireless network type. The disadvantage of using radio wave or wireless network to realize cableless communication is that the communication signal is not Safety, easy to generate electromagnetic interference, high power consumption during long-distance transmission, power failure can not work normally, etc.
