Device and method for unlocking mobile terminal

Abstract

The invention relates to a device and a method for unlocking a mobile terminal, which belong to the field of telephone communication equipment. The method includes that a button module transmits locking state interrupting signals to the mobile terminal, the mobile terminal enters a half-locking state, a distance sensor is started to detect whether an object close to the mobile terminal exists and the distance between the object and the mobile terminal, and simultaneously a timer is started to monitor time of the mobile terminal in the half-locking state; when the distance sensor detects that the object close to the mobile terminal exists and the distance between the object close to the mobile terminal and the mobile terminal reaches a distance threshold value, the mobile terminal is unlocked, otherwise the mobile terminal keeps the half-locking state; and when a timing threshold value is reached, the distance sensor is shut down to lock the mobile terminal. The device and the method for unlocking the mobile terminal can avoid false triggering operation and loss of additional electric quantity completely, effectively prolong service life of the sensor, further enhance functional stability of mobile phones and other mobile terminals, and improve user experience.

Description

technical field [0001] The invention relates to an unlocking device and method for a mobile terminal, belonging to the technical field of telephone communication. Background technique [0002] At present, with the development and wide application of communication equipment such as mobile phones, in order to meet the confidentiality requirements for information and improve the security performance of related equipment, many products basically have a structure with unlocking and locking functions. It is a specific combination of buttons on terminal equipment such as mobile phones to achieve corresponding functions. In addition, there are methods such as button plus touch screen sliding, distance sensor sensing distance, acceleration sensor position sensing, etc. to unlock and lock the device. , these unlocking methods may fail to a certain extent, and once the unlocking settings fail, the user will not be able to use the device normally, which will affect the user's related wo...

Problems solved by technology

The invention uses a distance sensor to detect whether there is an NFC device paired with a short-distance communication terminal approaching, and when the baseband processor does not receive an interrupt signal, the NFC module is in a power-saving state, thereby saving battery power. At the same time, the application of the distance sensor improves The intelligence of the communication terminal, but the invention does not carry out corresponding control on the distance sensor itself, so that the battery loss of the device itself and the stability of the operation are insufficient.
