Embodiment 1

[0039] The embodiment of the present invention provides a method for information transmission, such as figure 1 As shown, the processing flow of the information sending end in this method may include the following steps:

[0040] Step 101, the first terminal acquires the information to be transmitted, and acquires the encoding of the information to be transmitted in the target encoding format.

[0041] In step 102, the first terminal determines a color sequence for optical signal transmission according to the stored correspondence between codewords and colors and the acquired codeword sequence in encoding.

[0042] Step 103, the first terminal transmits optical signals of each color to the second terminal according to the order of the colors in the color sequence used for optical signal transmission.

[0043] Such as figure 2 As shown, the processing flow of the information receiving end in the method may include the following steps:

[0044] Step 201, the second terminal ...

Embodiment 2

[0049] An embodiment of the present invention provides an information transmission method, which can be applied to information transmission between two terminals, and the two terminals are preferably mobile terminals such as mobile phones or tablet computers.

[0050] The following will be combined with specific implementation methods to figure 1 The processing flow shown will be described in detail, and the content may be as follows.

[0051] Step 101, the first terminal acquires the information to be transmitted, and acquires the encoding of the information to be transmitted in the target encoding format. Wherein, the information to be transmitted may be text information or other data information.

[0052] Preferably, the target encoding format can be a Morse code format, and in the encoding of the Morse code format, code words such as dot (dot), dash (dash) and spacers can be included, represented by a combination of dot, dash and interval characters (letters or numbers)....

Embodiment 3

[0101] Based on the same technical concept, an embodiment of the present invention also provides an information transmission device, which may be the above-mentioned first terminal or a processing unit in the first terminal, such as Figure 7 As shown, the device includes:

Abstract

The invention discloses an information transmission method and device, and belongs to the technical field of computers. The information transmission method comprises the steps that a first terminal acquires information to be transmitted, and acquires the code of the information to be transmitted in a target coded format; the first terminal determines a color sequence used for emitting optical signals according to a stored corresponding relation between a code word and a color as well as a code word sequence in the code; and the first terminal emits optical signals of various colors to a second terminal according to the sequence of various colors in the color sequence used for emitting the optical signals. With the adoption of the information transmission method and device, the efficiency of information transmission through the optical signals between the terminals can be improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for information transmission. Background technique [0002] With the development of mobile communication technology, mobile terminals such as mobile phones are becoming more and more popular in people's daily life, and communication means are also becoming more and more abundant. However, in some cases where the radio signal is poor (or even no radio signal), for example, in remote mountainous areas or remote corners where the mobile operator's network cannot cover, people's use of mobile phones to communicate will be affected and cannot pass Mobile phone for information transmission. [0003] In order to solve this problem, the general solution is to emit visible light through the LED (Light Emitting Diode) lamp or screen of the mobile phone, and receive the signal through the camera or other light sensing devices, so as to realize information transmission...
