Embodiment Construction

[0052] The claimed invention is now described with reference to the drawings, wherein like reference numerals are used to refer to like parts or steps throughout. In the following description, for purposes of explanation, numerous specific details are disclosed in order to provide a thorough understanding of claimed subject matter. It will be apparent, however, that the inventions may be practiced without these specific details.

[0053] Embodiments of the present invention propose an optical or acoustic wave communication method. This communication method is mainly based on one-way light or sound wave communication. Moreover, the embodiment of the present invention introduces an additional auxiliary communication channel to add a verification, and triggers data transmission on the main communication channel after the verification is passed. In this way, the sending end can directly send communication data without manual operation, which is more convenient to use. And for v...

Abstract

The invention relates to an optical or acoustic communication method and system. The optical communication method comprises the following steps that: transmission signals carrying indication information is transmitted to a transmitting end of light from a receiving end of visible light; the transmission signals are received and decoded at the transmitting end, such that the indication information can be verified; and the indication information is responded, and optical communication signals containing communication data are transmitted to the receiving end from the transmitting end.

Description

technical field [0001] The present invention relates to the communication field, in particular to an optical or sound wave communication method and system. Background technique [0002] Optical communication is a new, short-distance, high-speed wireless optical communication technology developed on the basis of LED technology. The basic principle of optical communication is to use the characteristics of light-emitting diodes (LEDs) to switch faster than fluorescent lamps and incandescent lamps, and to communicate through high-frequency flickering of LED light sources. Lights represent a binary 1, and no light represents a binary 0. High-speed optical signals containing digital information can obtain information through photoelectric conversion. Optical communication technology can be used to make optical encryption keys because its data is not easy to be interfered and captured, and optical communication equipment is simple to manufacture and should not be damaged or degau...
