Example Embodiment

[0057] Example 1

[0058] The embodiment of the present invention provides a data communication method, such as figure 1 Shown, including:

[0059] S1. The terminal obtains the model of the terminal;

[0060] Among them, the model of the terminal may be represented by models such as IPhone5s, Samsung N7108, etc. Generally, the terminal's hardware, software, supported encoding methods, communication rate and other performance can be determined according to the model of the terminal.

[0061] Optionally, in this embodiment, the obtaining of the terminal model may be that the APP on the terminal prompts the user to input, and the APP receives the terminal model input by the user, or the APP on the terminal displays several The model of the terminal to prompt the user to make a selection, and the APP obtains the model of the terminal selected by the user.

[0062] Optionally, in this embodiment, the model of the acquiring terminal may be obtained through detection by the terminal. Exempl...

Example Embodiment

[0107] Example 2

[0108] The embodiment of the present invention provides a terminal, such as image 3 As shown, the terminal includes:

[0109] The obtaining unit 21 is configured to obtain the model of the terminal;

[0110] The model of the terminal, for example, can be represented by models such as IPhone5s and Samsung N7108. Generally, the terminal's hardware, software, supported encoding methods, communication rate and other performance can be determined according to the model of the terminal.

[0111] The searching unit 22 is configured to look up whether there is an encoding method corresponding to the model of the terminal in the preset mapping table;

[0112] Wherein, the encoding method is a frequency offset modulation FSK encoding method. In the FSK encoding method, M sampling points are used to obtain a sine wave with a period of T1 to represent logic 0, and N sampling points are used to obtain a sine wave with a period of T2. Sine wave represents logic 1, M≠N, T1≠T2, M ...

Abstract

The invention provides a data communication method, a terminal and information security equipment. The method includes the steps that the terminal obtains the terminal type; if an encoding mode corresponding to the terminal type is found, a first audio data package is encoded by the terminal in the encoding mode corresponding to the terminal type; otherwise, a second audio data package is encoded by the terminal in at least two encoding modes different from each other, and at least two encoded second audio data packages are sent to the information security equipment through an audio interface; the encoded second audio data packages are decoded through the information security equipment; the bit error rate of each second audio data package is calculated, and mark information of a target encoding mode is sent to the terminal; the target encoding mode is the encoding mode which is adopted for the second audio data package with the lower bit error rate; the first audio data package is encoded in the target encoding mode by the terminal; the encoded first audio data package is sent to the information security equipment by the terminal through the audio interface.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a data communication method, terminal and information security equipment. Background technique [0002] When the mobile phone communicates with the information security device, for example, the mobile phone sends data to the information security device through the audio interface, the mobile phone will use a certain encoding method to encode the data to be sent, and send the encoded data to the information security device. [0003] Generally, when a mobile phone sends data through an audio interface, it supports multiple encoding methods. [0004] However, in the prior art, the mobile phone cannot realize the selection of the coding mode. Contents of the invention [0005] The present invention aims to solve the above-mentioned problem that the mobile phone cannot realize the selection of the coding mode. [0006] The main purpose of the present invention is to provide a ...
