Equipment connection method, device and system

Abstract

The invention discloses an equipment connection method and a device, an equipment access method and a device, and an equipment connection system, which relate to the technical field of computers. The equipment connection method comprises steps: whether an audio interface of a first piece of equipment is inserted is detected; if the audio interface of the first piece of equipment is detected to be inserted, a first audio signal is sent via the audio interface, wherein the first audio signal is used for indicating to acquire wireless connection permission information of target equipment, a second audio signal is received via the audio interface, and the second audio signal comprises the wireless connection permission information of the target equipment; and according to the wireless connection permission information in the second audio signal, the first piece of equipment and the target equipment are wirelessly connected. The operation steps for enabling the first piece of equipment to be connected with the target equipment by the user are reduced, the user operation tedious degree is reduced, the secrecy degree is high, the application range is wide, and needs of the majority of users can be met.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a device connection method, device and system. Background technique [0002] With the development of technology, people use mobile terminals more and more frequently, and in the process of using mobile terminals, people use the mobile terminal to interact with other devices to transmit or obtain information more and more frequently. For example, a user connects a mobile terminal to a wifi (wireless fidelity, wireless fidelity) device to access the Internet; Receive data, such as transmitting pictures, videos, documents, etc.; another example, a user passes a mobile terminal through OTG (On-The-Go, which is a technology that realizes data transmission between devices without network nodes) Connect to another user's device to transmit or receive data. [0003] The user's mobile terminal is connected to a certain device through various methods similar to the above, and...

AI Technical Summary

Problems solved by technology

[0013] However, for the above-mentioned first connection method, it is easy to cause connection failure due to human-made password input errors; the user's operation is cumbersome, and the whole process takes a long time; Device IDs and passwords are easily stolen by others

[0014] For the above-mentioned second connection method, the mobile terminal needs to have a camera, and the connected device has a display screen. There are still certain requirements for the camera’s accuracy and auto focus, and the user operation is relatively cumbersome.

[0015] For the above third connection method, since many mobile terminals do not contain NFC modules, its application range is narrow and cannot meet the needs
