Problems solved by technology

In order to unlock the device, the user needs to enter the password in various ways, yet the inconvenience associated with this traditional unlocking method often leads to complaints
On the other hand, although there are fingerprint unlocking devices on the market, this brings additional hardware costs and limits the wide application on mobile terminals.

Embodiment Construction

[0028] See attached figure 1 , a flow diagram of a mobile terminal unlocking method based on a built-in distance sensor. After the device is turned on, the user should select whether to enable the distance sensing unlocking function in the setting menu, and set the upper and lower limit thresholds of the distance (dmin, dmax) and a reasonable Delay t. Then when the user wakes up the device from hibernation, the unlock judgment will be performed. The device processor reads the sensor data at intervals of tens of milliseconds, and the software converts it into actual distance. Judging whether the distance sensed to the object is greater than or equal to dmin and less than or equal to dmax, if so, start the timer, otherwise return to continue the initial judgment. After the timer is started, it continues to obtain the sensing distance every tens of milliseconds. When the distance is less than dmin or greater than dmax, the timer is reset and stopped, and returns to continue the...

Abstract

The invention provides a mobile terminal unlocking method based on a built-in distance sensor. The mobile terminal unlocking method based on a built-in distance sensor includes the steps: 1) a distance sensor is arranged in a mobile smart terminal device; 2) a user moves a shielding object overhead the sensor, and obtains the distance data of the shielding object through the distance sensor; 3) the distance sensor is connected with a central processing chip in the mobile smart terminal device, and the central processing chip is used for obtaining the data of the distance sensor; 4) the central processing chip uploads the obtained data to special software to perform noise reduction, and obtains the practical distance of the shielding object through conversion; and 5) if the practical distance is determined to be maintained beyond a special time, the device can be unlocked. The invention also provides a mobile terminal unlocking apparatus based on a built-in distance sensor. The mobile terminal unlocking apparatus based on a built-in distance sensor is more convenient on the premise of guaranteeing safety, and uses the distance sensor contained in the device, thus saving the cost and being more mature in technology.

Description

technical field [0001] The invention relates to an unlocking technology of a smart terminal and a mobile device, in particular to a method and device for unlocking a mobile terminal based on a built-in distance sensor. Background technique [0002] With the miniaturization of electronic equipment and the development of the Internet, mobile smart terminals are becoming more and more popular, appearing in people's lives in various forms, as a necessary way for the public to realize convenient interaction in the fields of communication, entertainment, control, and smart home. Due to the public's concern about data security and privacy, terminals often have a built-in timeout lock function. In order to unlock a device, a user needs to input a password in various ways, yet the inconvenience accompanying this conventional unlocking method often leads to complaints. On the other hand, although fingerprint unlocking devices appear on the market, this brings additional hardware cost...
