Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In a preferred embodiment of the present invention, as shown in fig. 1, the method for dynamically starting a fingerprint module of a mobile terminal includes the following steps:
step S100, a distance change detection system is preset.
Preferably, the step S100 specifically includes:
step S101, when the mobile terminal is produced, a distance change detection system is preset;
and S102, connecting one end of the distance change detection system with the mobile terminal fingerprint module, and fixing the other end.
When the mobile terminal is produced, a distance change detection system with high sensitivity is preset for detecting the distance between the first capacitor plate and the second capacitor plate, one end of the distance change detection system is connected with the mobile terminal fingerprint module, the other end of the distance change detection system is fixed, and the distance change detection system is arranged so as to detect the distance between the first capacitor plate and the second capacitor plate and judge whether the mobile terminal fingerprint module needs to be started or not.
Preferably, as shown in fig. 2, fig. 2 is a schematic structural diagram of a distance change detection system in the method for dynamically starting the fingerprint module of the mobile terminal according to the present invention. The distance change detection system specifically includes: the fingerprint module comprises a spring 201, a first capacitor plate 202, a second capacitor plate 203 and a fingerprint module interface 204 used for being connected with the mobile terminal fingerprint module 20; one end of the spring 201 is connected with one end of the first capacitor plate 202, and the other end is fixed; the other end of the first capacitor plate 202 is connected to the fingerprint module interface 204; the second capacitor plate 203 is fixed. For example, when a user touches the mobile terminal fingerprint module 20 with a finger, the fingerprint module interface 204 slightly displaces, so that the first capacitor plate 202 connected to the fingerprint module interface 204 moves, the spring 201 connected to the other end of the first capacitor plate 202 shortens, and the distance between the first capacitor plate 202 and the second capacitor plate 203 changes. Similarly, when the user's finger leaves the mobile terminal module 20, the spring 201 returns to its original length, the first capacitor plate 202 moves to its original position, and the distance between the first capacitor plate 202 and the second capacitor plate 203 changes. Judge whether mobile terminal fingerprint module need open through the distance between first capacitor plate 202 among the detection distance change detecting system and the second capacitor plate 203, avoided making mobile terminal be in the state of opening fingerprint sensor collection user's fingerprint always, reduced the battery energy consumption, prolonged the life of fingerprint module.
And S200, when a user touches the fingerprint module of the mobile terminal, the distance change detection system detects the distance between the first capacitor plate and the second capacitor plate.
Preferably, the step S200 specifically includes:
step S201, when a user touches a fingerprint module of the mobile terminal, the mobile terminal receives an operation instruction of the user;
step S202, the distance change detection system starts to detect the distance between the first capacitor plate and the second capacitor plate.
During specific implementation, when a user needs to unlock the mobile terminal, the user touches the fingerprint module of the mobile terminal, the mobile terminal receives an operation instruction of the user, and the distance change detection system starts to detect the distance between the first capacitor plate and the second capacitor plate.
Preferably, the distance between the first capacitor plate 202 and the second capacitor plate 203 is detected according to the present invention, and it is first required to satisfy C = ∈ S/D, where C is the capacitance between the first capacitor plate 202 and the second capacitor plate 203, ∈ is the dielectric constant between the first capacitor plate 202 and the second capacitor plate 203, S is the facing area between the first capacitor plate 202 and the second capacitor plate 203, and D is the distance between the first capacitor plate 202 and the second capacitor plate 203. Wherein epsilon and S are constants, the distance D between the first capacitor plate 202 and the second capacitor plate 203 can be obtained by only obtaining the capacitance C between the first capacitor plate 202 and the second capacitor plate 203.

On the other hand, Q can also be obtained by the formula Q = It, where I is the current for charging the capacitor C and t is the charging time; however, the charging current is variable, the charging process is not easy to control, and the charging capacity of the charging capacitor C is equal to the discharging capacity of the discharging capacitor C, so the present invention adopts the discharging process to obtain the electric quantity Q, and the schematic diagram of the structure is shown in fig. 3, where fig. 3 is a schematic diagram of the structure for obtaining the electric quantity Q of the capacitor C formed by the first capacitor plate and the second capacitor plate in the method for dynamically starting the fingerprint module of the mobile terminal of the present invention. The method comprises the following specific steps:
step 1, filling a capacitor C between a first capacitor plate 202 and a second capacitor plate 203, starting a timer with timeout time of 10 microseconds, and setting a variable Q to zero; specifically, the process of charging the capacitor C is to charge the capacitor C between the first capacitor plate 202 and the second capacitor plate 203 by applying a voltage U across the capacitor C for a period of time to full charge; the time period can be determined experimentally as the time required for the capacitor C to fill, for example 0.3 seconds.
And 2, judging whether the timer is overtime, if so, executing the step 3, and if not, repeatedly executing the step 2.
Step 3, acquiring a voltage U1 at two ends of a resistor R in the electric quantity acquisition module 303, judging whether U1 is zero, if so, executing step 5, otherwise, executing step 4; this process is accomplished by the voltage acquisition module 302.
Step 4, according to the formula Q = 10-5(U1/R) + Q calculation, after which step 2 is repeated.
Step 5, the electric quantity obtaining module 303 obtains the electric quantity Q when the capacitor C formed by the first capacitor plate 202 and the second capacitor plate 203 is fully charged.
Thus, Q is obtained, the capacitance C between the first capacitor plate 202 and the second capacitor plate 203 is obtained according to the formula C = Q/U, and the distance D between the first capacitor plate 202 and the second capacitor plate 203 is further obtained according to the formula C = ∈ S/D. For example, when a user touches the fingerprint module of the mobile terminal, the distance D between the first capacitor plate and the second capacitor plate in the distance change detection system is detected, and the mobile terminal judges whether to open a fingerprint to detect and identify the fingerprint of the user and unlock the fingerprint.
Step S300, when the fact that the distance between the first capacitor plate and the second capacitor plate is smaller than a first distance threshold value is detected, controlling a fingerprint module of the mobile terminal to start fingerprint detection; when detecting that the distance between first capacitor plate and the second capacitor plate is greater than the second distance threshold, controlling the fingerprint module of the mobile terminal to close fingerprint detection.

Preferably, the step S300 further includes:
and S000, presetting a first distance threshold and a second distance threshold between the first capacitor plate and the second capacitor plate, wherein the first distance threshold is smaller than the second distance threshold.
In specific implementation, the first distance threshold and the second distance threshold are preset, and the first distance threshold is smaller than the second distance threshold, for example, the first distance threshold is set to be 5mm, and the second distance threshold is set to be 8 mm. The distance change detection system starts to detect the distance between the first capacitor plate and the second capacitor plate, and when the distance D between the first capacitor plate and the second capacitor plate is detected to be smaller than a first distance threshold value, the mobile terminal fingerprint module is controlled to start fingerprint detection; when detecting first capacitor plate with when distance D between the second capacitor plate is greater than the second distance threshold, control mobile terminal fingerprint module and close fingerprint detection, realize the purpose that the fingerprint detection of dynamic control mobile terminal fingerprint module opened and closed from this.
