An optical label based on space division multiplexing and its sharing method and equipment

Abstract

The invention discloses an optical label based on space division multiplexing and sharing method and device thereof. According to the invention, the data dissemination that is carried out in the information area of the optical label is broken up into sub-regions by means of the space division of the optical label; and a plurality of optical label information sources are corresponded to different sub-regions of an optical label in a one-to-one way by the sharing allocation controller; therefore, the sharing of the plurality of information sources of the optical label is realized, the process issimple and reasonable, the online application and online quit can be performed, the designed sharing allocation controller can be connected to the Internet, and the universality is good; and the sharing method of the optical label based on the space division multiplexing is designed based on the information interaction of the optical label and the real-time editing characteristic, which the otherlabel methods do not have at present.

Description

technical field [0001] The invention relates to the sharing of optical tags, in particular to an optical tag based on space division multiplexing and its sharing method and equipment. Background technique [0002] Optical tags provide a longer recognition distance than QR codes and barcodes, and have the advantages of strong directivity and large amount of information. They have a wide range of uses in social economy, commercial sales, etc., and there will be more and more optical tags in the future. Hashtags appear around people's daily lives. However, due to the limitation of geographical space, in the dense commercial area, the layout of optical tags cannot be arranged in the erection space without restriction. The optical tags, ordinary billboards and lighting areas must be fully and reasonably arranged so that they will not interfere with each other. impact; this may lead to the fact that not every optical label issuer (optical label information source) can independent...

Problems solved by technology

However, due to the limitation of geographical space, in the dense commercial area, the layout of optical tags cannot be arranged in the erection space without restriction. The optical tags, ordinary billboards and lighting areas must be fully and reasonably arranged so that they will not interfere with each other. impact; this may lead to the fact that not every optical label issuer (optical label information source) can independently set up its own optical label sign, so that the optical labels in the prior art cannot be shared, and multiple optical labels cannot be issued through one optical label. information, resulting in a waste of installation space and the amount of information on the optical tag itself
