Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a terminal unlocking method according to a first embodiment of the present invention. As shown in fig. 1, the terminal unlocking method of this embodiment may at least include the following steps:
in step S11, the terminal acquires at least two level signals corresponding to the at least two secondary unlocking keys that are triggered.
In this embodiment, a plurality of auxiliary unlocking keys are preset in the terminal, and when a user unlocks the terminal by using the auxiliary unlocking keys, the corresponding auxiliary unlocking keys can be triggered by pressing or touching the auxiliary unlocking keys. In this embodiment, a plurality of preset auxiliary unlocking keys are provided with corresponding level signals, and when the terminal senses which auxiliary unlocking keys are triggered by the user, the terminal can read the corresponding level signals according to the triggered auxiliary unlocking keys. For example, 6 auxiliary unlocking keys a to F are preset, in this embodiment, the 6 auxiliary unlocking keys are respectively provided with corresponding level signals a to F, and when a user uses the auxiliary unlocking keys to unlock, B, C, D of the auxiliary unlocking keys are triggered, so that the corresponding level signals b, c, and d can be obtained according to B, C, D of the triggered auxiliary unlocking keys.
In this embodiment, when the auxiliary unlock key triggered by the user is sensed, the trigger sequence of the triggered auxiliary unlock key may be acquired, so that when the level signal corresponding to the triggered auxiliary unlock key is acquired, the acquisition sequence of the level signal is consistent with the trigger sequence of the auxiliary unlock key, that is, the acquisition sequence of the level signal is acquired according to the trigger sequence of at least two triggered auxiliary unlock keys.
In this embodiment, the multiple auxiliary unlocking keys may be virtual keys or physical keys different from the original virtual keys or physical keys of the terminal, and the auxiliary unlocking keys are not displayed when the terminal normally works, but are displayed again on the touch screen of the terminal when the terminal cannot unlock by using the original virtual keys or physical keys; in addition, the auxiliary unlocking key may also reuse an original virtual key or an original physical key of the terminal, for example, when the terminal cannot unlock the terminal by using the original function of the original virtual key or the original physical key, the function of the virtual key or the original physical key is reset, the virtual key or the original physical key is used as a temporary auxiliary unlocking key, and after the terminal is unlocked, the function of the virtual key or the original physical key is set to the original function. For example, in a normal situation, the terminal is unlocked by using ten numeric keys of 0 to 9, when it is determined that the terminal cannot be unlocked by using the ten numeric keys, a numeric input function originally corresponding to the ten numeric keys is converted into an auxiliary unlocking function, and then the ten numeric keys are used as auxiliary unlocking keys, and at this time, the numeric keys are triggered to not perform numeric input any more, but level signals corresponding to the numeric keys are acquired.
In step S12, level signal traces corresponding to the at least two auxiliary unlocking keys are calculated using the at least two level signals.
By using the level signal acquired in step S11, a level signal trajectory corresponding to the triggered auxiliary unlock key can be obtained from the level signal of each triggered auxiliary unlock key.
In step S13, the terminal is unlocked using the level signal trajectory.
Further, the terminal may unlock using the level signal trace obtained in step S12.
According to the terminal unlocking method provided by the embodiment, the level signal track corresponding to the triggered auxiliary unlocking key is calculated by acquiring the level signal of the triggered auxiliary unlocking key, the terminal is unlocked by using the level signal track, and then when the terminal is unlocked and invalidated through terminal unlocking modes such as numbers, biological information and/or touch gestures, the terminal can be unlocked by replacing the terminal unlocking modes such as the numbers, the biological information and/or the touch gestures of the terminal, so that the probability of terminal unlocking invalidation is reduced, and the user experience is improved.
Further, the level signal in the present embodiment may be a level amplitude. Referring to fig. 2, as shown in fig. 2, the step S11 shown in fig. 1 at least includes the following steps:
in step S111, at least two level values corresponding to the triggered at least two secondary unlocking keys are acquired.
In this embodiment, each auxiliary unlocking key is provided with a corresponding level value, when a user unlocks the terminal by using the auxiliary unlocking key, the corresponding auxiliary unlocking key can be triggered by pressing or touching, and after the terminal senses that the auxiliary unlocking key is triggered by the user, the corresponding level values of the triggered auxiliary unlocking keys can be sequentially acquired according to the triggering sequence of the auxiliary unlocking keys by the user.
In step S112, corresponding at least two level voltages are calculated from the at least two level values.
Further, after the acquired level value corresponding to the triggered auxiliary unlocking key is obtained, the acquired level value is converted into a corresponding level voltage.
In step S113, at least two level voltages are converted into corresponding at least two level amplitudes.
Further, the calculated level voltage is converted into a corresponding level amplitude, and the level voltage is represented by the level amplitude.
Referring to fig. 3, as shown in fig. 3, the step S12 shown in fig. 1 at least includes the following steps:
in step S121, the magnitude relationship between the first level signal and the second level signal that are adjacent to each other in sequence in the at least two level signals is compared to obtain a comparison result.
In this embodiment, the terminal may obtain a plurality of level signals, make the level signal obtained first in every two adjacent level signals be the first level signal, make the level signal obtained later be the second level signal, compare the magnitude relationship of two adjacent level signals, and obtain a corresponding comparison result. It is understood that, in the present embodiment, more than two level signals can be obtained, and a corresponding plurality of comparison results can be obtained by correspondingly comparing two level signals.
For example, a user triggers B, C, D three auxiliary unlocking keys, and then corresponding level signals b, c, and d can be acquired according to B, C, D triggered auxiliary unlocking keys, wherein the level signals b and c are adjacent, when level signal tracks corresponding to the level signals b and c are calculated, the level signal b is a first level signal, the level signal c is a second level signal, and the level signals b and c are compared to obtain a corresponding comparison result; the level signals c and d are adjacent, when level signal tracks corresponding to the level signals c and d are calculated, the level signal c is a first level signal, d is a second level signal, and the level signals c and d are further compared to obtain corresponding comparison results, namely two different comparison results are obtained.
In step S122, level signal sub-trajectories between the first level signal and the second level signal which are sequentially adjacent are calculated, respectively, based on the comparison result.
In this embodiment, the comparison result between two adjacent level signals can be obtained through step S121, and then the level signal sub-trace between the two adjacent level signals can be calculated through the comparison result between the two adjacent level signals. It is understood that the level signal sub-trace between a plurality of adjacent two level signals is obtained in step S121.
For example, step S121 may obtain a comparison result between adjacent level signals b and c in the level signals b, c, d, thereby calculating a level signal sub-trace between adjacent level signals b and c; furthermore, the result of comparison between adjacent level signals c and d can be obtained, and thus the level signal sub-trace between adjacent level signals c and d can be calculated.
In step S123, level signal sub-tracks between the first level signal and the second level signal that are adjacent in sequence are combined to obtain level signal tracks corresponding to at least two auxiliary unlocking keys.
Step S122 obtains a level signal sub-trajectory between each two adjacent level signals, and then the level signal sub-trajectories obtained in step S122 may be combined to obtain a level signal trajectory corresponding to each level signal, that is, to obtain level signal trajectories corresponding to at least two triggered auxiliary unlock keys.
Further, the level signal sub-trajectories between each two adjacent level signals obtained in step S122 are mutually independent line segments, and correspondingly, combining the level signal sub-trajectories between each two adjacent level signals at this time is to connect the level signal sub-trajectories according to the triggering sequence of the corresponding triggered auxiliary unlocking key by the obtained multiple independent line segments.
For example, a level signal sub-trace between adjacent level signals b and c and a level signal sub-trace between adjacent level signals c and d are obtained in step S122; thus, the two obtained level signal sub-traces are combined according to the obtaining order of the level signals b, c, and d, so as to obtain the level signal traces corresponding to the level signals b, c, and d, in other words, the level signal traces corresponding to the triggered auxiliary unlocking key B, C, D.
Further, as shown in fig. 4, according to the difference of the comparison result obtained in step S121, step S122 may include the following steps:
in step S122a, a calculation is performed according to the first level signal and the second level signal by using the first trajectory equation, and a level signal sub-trajectory between the first level signal and the second level signal which are adjacent in sequence is obtained.
In the present embodiment, different methods may be employed to calculate the level signal sub-trajectory according to the comparison result obtained in step S121. When the obtained comparison result is that the first level signal is greater than the second level signal, step S122a is executed, that is, the level signal sub-trajectory is calculated by using the first trajectory equation, further, the level signal difference between the first level signal and the second level signal is calculated, the level signal difference is substituted into the first trajectory equation to obtain a corresponding curve trajectory, and further, the curve trajectory is subjected to differential calculation to obtain a line segment trajectory corresponding to the curve trajectory.
For example, determining that the first level signal is greater than the second level signal according to the comparison result, calculating a level signal difference Δ V1 between the first level signal and the second level signal, where Δ V1 is greater than 0, and where a (-t) is a first trajectory equation (where a is a non-zero natural number, t is an abscissa, and the value of the level signal is an ordinate), substituting the value of Δ V1 into the trajectory equation to obtain a corresponding curve trajectory, performing differential calculation on the curve trajectory to obtain a segment trajectory corresponding to the curve trajectory, where the segment trajectory is a level signal sub-trajectory between the first level signal and the second level signal; the starting point of the level signal sub-track is the level signal difference value Δ V1 as the starting point, and the end point approaches the end point of the level signal difference value Δ V1.
In step S122b, a calculation is performed according to the first level signal and the second level signal by using the second trajectory equation, and a level signal sub-trajectory between the first level signal and the second level signal which are adjacent in sequence is obtained.
When the obtained comparison result is that the first level signal is smaller than the second level signal, step S122b is executed, that is, the level signal sub-trajectory is calculated by using the second trajectory equation, further, the level signal difference between the first level signal and the second level signal is calculated, the level signal difference is substituted into the second trajectory equation to obtain a corresponding curve trajectory, and further, the curve trajectory is subjected to differential calculation to obtain a line segment trajectory corresponding to the curve trajectory.
For example, determining that the first level signal is smaller than the second level signal according to the comparison result, calculating a level signal difference Δ V1 between the first level signal and the second level signal, where Δ V1 is smaller than 0, and a trajectory formula y is a (t) as a second trajectory equation (where a is a non-zero natural number, t is an abscissa, and the value of the level signal is an ordinate), substituting the value of Δ V1 into the trajectory equation to obtain a corresponding curve trajectory, performing differential calculation on the curve trajectory to obtain a segment trajectory corresponding to the curve trajectory, where the segment trajectory is a level signal sub-trajectory between the first level signal and the second level signal; the starting point of the level signal sub-track is the level signal difference value Δ V1 as the starting point, and the end point approaches the end point of the level signal difference value Δ V1.
It is to be understood that the trajectory formula y ═ a (-t) and y ═ a (t) are merely examples of the application of the first trajectory equation and the second trajectory equation, and in other embodiments, the first trajectory equation and the second trajectory equation may adopt other trajectory equations, for example, the trajectory formula y ═ a (t) is the first trajectory equation, and the trajectory formula y ═ a (-t) is the second trajectory equation, which is not limited in particular.
Referring to fig. 5, as shown in fig. 5, the step S13 shown in fig. 1 at least includes the following steps:
in step S131, the level signal trace is converted into a corresponding clock signal.
In step S132, the terminal is unlocked using the clock signal.
In this embodiment, the obtained level signal track is not directly used to unlock the terminal, but the level signal track is sent to the central processing unit, and the central processing unit obtains a corresponding clock signal according to the level signal track, and then unlocks the terminal through the clock signal.
Further, referring to fig. 6, fig. 6 is a flowchart illustrating a terminal unlocking method according to a second embodiment of the present invention. As shown in fig. 6, the terminal unlocking method of this embodiment may at least include the following steps:

In this embodiment, the auxiliary unlocking key is set to be a key different from an original virtual key or an original physical key of the terminal, and the auxiliary unlocking key is not displayed when the terminal normally works and the terminal can be unlocked by using the original virtual key or the original physical key of the terminal, but is displayed again on the touch screen of the terminal when the terminal cannot be unlocked by using the original virtual key or the original physical key of the terminal. In other embodiments, the auxiliary unlocking key may also reuse an original virtual key or an original physical key of the terminal, for example, when the terminal cannot unlock the terminal by using the original function of the original virtual key or the original physical key, the function of the virtual key or the original physical key is reset, the virtual key or the original physical key is used as a temporary auxiliary unlocking key, and after the terminal is unlocked, the function of the virtual key or the original physical key is set to the original function.
In this embodiment, when the terminal cannot unlock by using the original virtual key or the original physical key, it is determined that the default unlocking mode of the terminal is invalid, and at this time, the auxiliary unlocking key is activated, the auxiliary unlocking key displayed on the touch screen of the terminal, or the virtual key or the physical key is used as a temporary auxiliary unlocking key.

Further, referring to fig. 7, fig. 7 is a flowchart illustrating a terminal unlocking method according to a third embodiment of the present invention. As shown in fig. 7, the terminal unlocking method of this embodiment may at least include the following steps:

And when the terminal starts the auxiliary unlocking key, the user can unlock the terminal by using the auxiliary unlocking key. In this embodiment, the user may set the preset number of the auxiliary unlocking keys that need to be triggered during unlocking, and when the number of the auxiliary unlocking keys triggered by the user reaches the preset number, it is determined to end the triggering of the auxiliary unlocking keys. For example, if the number of the auxiliary unlocking keys triggered by the user reaches 5, the user determines to end the triggering of the auxiliary unlocking keys, and at this time, the user triggers other auxiliary unlocking keys in time, and the auxiliary unlocking keys which are continuously triggered are also used as invalid input. The preset number can be set by the user according to the preference and the use habit of the user, and the preset number can be set to be 4, 6 or 9, and the invention is not particularly limited.

In step S42, the terminal acquires at least two level signals corresponding to the at least two secondary unlocking keys that are triggered.

Further, in the present embodiment, the second to fourth embodiments of the terminal unlocking method shown in fig. 6 to 8 may be combined with each other to form a new embodiment. For example, the second embodiment of the terminal unlocking method shown in fig. 6 may be combined with the third embodiment of the terminal unlocking method shown in fig. 7, and thus, step S21 may be further performed before step S31 is performed. Accordingly, the second embodiment of the terminal unlocking method shown in fig. 6 may be combined with the fourth embodiment of the terminal unlocking method shown in fig. 8, and thus, step S21 may be further performed before step S41 is performed.
