Ship light signal coding mode capable of achieving quick bilingual receiving and sending

Abstract

The invention discloses a ship light signal coding mode capable of achieving quick bilingual receiving and sending. A more concise combination of short flashing and long flashing is used for expressing numerical codes, the numerical code combination expressing Chinese characters is further simplified, the more concise numerical code combination expresses the commonly used Chinese characters, and therefore light signals are received and sent through the Chinese language. The ship light signal coding mode can improve the lamp signal receiving and sending speed and accuracy, avoid errors and interference of human factors, and rapidly express any complex character content. By utilization of the coding mode, quick light signal receiving and sending are performed, the mode is convenient and easy to learn, the technical requirement for using lamp signals is reduced, labor cost for using the lamp signals is lowered, the range for using the lamp signals is enlarged, and general fishing boats can use the lamp signals.

Description

technical field [0001] The invention relates to the field of ship light communication, in particular to a ship light signal coding method capable of realizing bilingual fast transmission and reception. Background technique [0002] Light communication (light language) is one of the communication methods commonly used by marine ships. At present, light communication mainly relies on manual transmission and human reading, so the speed is greatly limited, so that light communication is limited to conveying very simple semantics. [0003] At present, the commonly used light communication code in the world is Morse code (Morse), which represents dots and dashes by short and long flashes (the length of dashes is 3 times that of dots), and then letters and numbers are represented by the combination of dots and dashes. . The length between the flash and the flash is the length of a flash point, which is called a dark spot; and the length of a flash stroke between letters and letter...

AI Technical Summary

Problems solved by technology

In Morse code, the combination of dots and dashes representing numbers is relatively long, and 4 numbers are used to represent a Chinese character. The combination of long flashes and short flashes used to express each Chinese character will be very long and relatively complicated. The method will not have much impact on the sending and receiving of telegrams, but for light signals, the speed is a factor that needs to be carefully considered. If the signal combination is too long and the encoding is too complicated, it will not only make communication very inconvenient, but also easy. generate error

[0005] Therefore, so far, there has not been any literature on the realization of Chinese sending and receiving in light communication.
