Embodiment Construction

[0054] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0055] An embodiment of the present invention relates to an optical communication device for transmitting information. The optical communication device is also referred to herein as an "optical tag", and the two may be used interchangeably throughout this application.

[0056] figure 1 Shown is an optical tag 100 including two light sources (respectively a first light source 101 and a second light source 102 ) according to an embodiment of the present invention. The light tag 100 also includes a controller, which is used to set the working mode of the first light source 101 and the second light source 102 . The controller can be integrated with the light source in a housing, or it can be far away from the light source, as long as it c...

Abstract

An optical communication apparatus and a method for transmitting and receiving information are provided. The optical communication device includes: at least two light sources including a first light source and a second light source; and a controller that is used for setting the light source to be in any one of at least two working modes, wherein the at least two working modes comprise a first working mode and a second working mode: when the first light source and the second light source are in the same working mode, the first light source and the second light source are used for transmitting first information, and when the first light source and the second light source are in different working modes, the first light source and the second light source are used for transmitting other information different from the first information.

Description

technical field [0001] The present invention belongs to the field of optical information technology, and more specifically relates to an optical communication device (also referred to as an "optical tag" herein) and a method for transmitting and receiving information. Background technique [0002] The statements in this section are only to provide background information related to the present invention to facilitate understanding of the present invention. Unless explicitly stated, the content described in this section does not constitute prior art for the technical solutions of this application. [0003] In the prior art, there is a method of transmitting information through light emitted by a light source, which makes the light source emit light in different ways according to the information to be transmitted, so as to transmit the corresponding information. The recipient of the information can receive the light from the light source and analyze it to identify the informat...
