Abstract

A data transmission method, where the data transmission method includes acquiring, by a first terminal, an output signal of a sensor of the first terminal, where the output signal of the sensor of the first terminal is a signal generated when a first magnet of a second terminal triggers the sensor of the first terminal, determining, by the first terminal, the output signal of the sensor of the first terminal as a low-level output signal, establishing, by the first terminal, a communication link with the second terminal, and determining, by the first terminal according to the communication link established by the first terminal with the second terminal, to perform data transmission with the second terminal.

First claim

What is claimed is:

1. A data transmission method, comprising: acquiring, by a first terminal, an output signal of a sensor of the first terminal, wherein the output signal of the sensor of the first terminal is a signal generated when a first magnet of a second terminal triggers the sensor of the first terminal; determining, by the first terminal, the output signal of the sensor of the first terminal as a low-level output signal; establishing, by the first terminal, a first communication link with the second terminal when the output signal of the sensor of the first terminal is the low-level output signal; and determining, by the first terminal according to the first communication link established by the first terminal with the second terminal, to perform data transmission with the second terminal, wherein the first terminal further comprises a second magnet disposed on a jacket of the first terminal, wherein the jacket is configured to hold and cover the first terminal, wherein the jacket can be removed from the first terminal, wherein before establishing, by the first terminal, the first communication link with the second terminal, the method further comprises: triggering, by the second magnet of the first terminal, the sensor of the first terminal to generate the low-level output signal when the second magnet approaches the sensor of the first terminal and when the first magnet of the second terminal does not trigger the sensor of the first terminal to generate a low-level output signal; and controlling, by the first terminal, a screen of the first terminal to enter a screen locking state.

2. The method according to claim 1 , further comprising:
determining, by the first terminal, that the low-level output signal of the sensor of the first terminal does not meet a first preset requirement, wherein the first preset requirement is that a pole S of the first magnet of the second terminal triggers the sensor of the first terminal to generate the low-level output signal;
determining, by the first terminal, that the low-level output signal of the sensor of the first terminal meets a second preset requirement, wherein the second preset requirement is that the second magnet of the first terminal triggers the sensor of the first terminal to generate the low-level output signal when approaching the sensor of the first terminal because the jacket of the first terminal is closed; and
controlling, by the first terminal, a screen of the first terminal to enter a screen locking state when the low-level output signal of the sensor of the first terminal meets the second preset requirement.

3. The method according to claim 1 , wherein after acquiring, by the first terminal, the output signal of the sensor of the first terminal, the method further comprises:
determining, by the first terminal, the output signal of the sensor of the first terminal as a high-level output signal, wherein the high-level output signal is another signal generated by triggering the sensor of the first terminal when the second magnet of the first terminal is far from the sensor of the first terminal because the jacket of the first terminal is open; and
controlling, by the first terminal, a screen of the first terminal to enter a screen unlocking state.

4. A terminal, comprising: a first magnet; a sensor; a processor; and a memory, wherein the first magnet, the sensor, the processor and the memory are in communication with each other, wherein the sensor is configured to be triggered by another first magnet of a second terminal to generate an output signal, wherein the memory is configured to store a program, and wherein the processor is configured to: execute the program stored by the memory; acquire the output signal of the sensor; determine the output signal of the sensor as a low-level output signal; control the terminal to establish a first communication link with the second terminal when the output signal of the sensor is the low-level output signal; and control, according to the first communication link established by the terminal with the second terminal, the terminal to perform data transmission with the second terminal, wherein the terminal further comprises a second magnet disposed on a jacket of the terminal, wherein the jacket is configured to hold and cover the terminal, wherein the jacket can be removed from the terminal, wherein before controlling the terminal to establish the first communication link with the second terminal, the processor is further configured to: trigger the sensor of the terminal to generate the low-level output signal when the second magnet approaches the sensor of the terminal and when the first magnet of the second terminal does not trigger the sensor of the terminal to generate a low-level output signal; and control a screen of the terminal to enter a screen locking state.

5. The terminal according to claim 4 , wherein the processor is further configured to:
determine that the low-level output signal of the sensor of the terminal does not meet a first preset requirement, wherein the first preset requirement is that a pole S of the first magnet of the second terminal triggers the sensor of the terminal to generate the low-level output signal;
determine that the low-level output signal of the sensor of the terminal meets a second preset requirement, wherein the second preset requirement is that the second magnet of the terminal triggers the sensor of the terminal to generate the low-level output signal when approaching the sensor of the terminal because the jacket of the terminal is closed; and
control a screen of the terminal to enter a screen locking state when the low-level output signal of the sensor of the terminal meets the second preset requirement.

6. The terminal according to claim 4 , wherein the processor is further configured to:
determine the output signal of the sensor of the terminal as a high-level output signal, wherein the high-level output signal is another signal generated by triggering the sensor of the terminal when the second magnet of the terminal is far from the sensor of the terminal because the jacket of the terminal is open; and
control a screen of the terminal to enter a screen unlocking state.

7. A data transmission system, comprising: a first terminal; and a second terminal in communication with the first terminal, wherein both the first terminal and the second terminal are equipped with a sensor and a first magnet, wherein the first terminal is configured to: acquire an output signal of the sensor of the first terminal, wherein the output signal of the sensor of the first terminal is a signal generated when the first magnet of the second terminal triggers the sensor of the first terminal; determine the output signal of the sensor of the first terminal as a low-level output signal; establish a first communication link with the second terminal; determine, according to the first communication link established by the first terminal with the second terminal, to perform data transmission with the second terminal, wherein the first terminal further comprises a second magnet disposed on a jacket of the first terminal, wherein the jacket is configured to hold and cover the first terminal, wherein the jacket can be removed from the first terminal, wherein before the first terminal establishes the first communication link with the second terminal, the first terminal is further configured to: trigger, by the second magnet of the first terminal, the sensor of the first terminal to generate the low-level output signal when the second magnet approaches the sensor of the first terminal and when the first magnet of the second terminal does not trigger the sensor of the first terminal to generate a low-level output signal; and control a screen of the first terminal to enter a sc
