It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that the NFC antenna is generally disposed on the rear cover of the mobile terminal due to its large area, so that the sensing distance of the NFC antenna can be effectively maintained. Then the lid is as mobile terminal's surface device, easily takes place to fall, the condition such as collide in the use to lead to the NFC antenna impaired, consequently need change the lid after can normally use the NFC function. Because the back covers of various types of mobile terminals may be the same, but the NFC antennas of the mobile terminals are different, when the back covers of the mobile terminals are replaced, the NFC function is easy to be abnormal.
In this regard, an embodiment of the present application provides an NFC function detection method, an apparatus, a storage medium, and a mobile terminal, where an execution main body of the NFC function detection method may be the NFC function detection apparatus provided in the embodiment of the present application, and the NFC function detection apparatus may be implemented in a hardware or software manner. In a specific embodiment, the NFC functionality detection apparatus may be integrated in a mobile terminal, for example, a terminal device such as a smart phone or a tablet computer.
The details will be described below separately.
Referring to fig. 1, fig. 1 is a schematic flowchart of an NFC function detection method provided in the embodiment of the present application, and a specific flowchart may be as follows:
101. and acquiring the distance between a first detection point arranged on the NFC antenna and a second detection point arranged on the main board of the mobile terminal.
In some embodiments, a trigger mechanism, such as an icon, a key, etc., may be provided in the mobile terminal, and after the mobile terminal changes the rear cover, a user may send a distance obtaining instruction through the trigger mechanism to obtain the distance between the first electrode plate and the second electrode plate. In some embodiments, a timer may be further disposed in the mobile terminal, and the distance between the first electrode plate and the second electrode plate is obtained at intervals of a preset time period, where the preset time period may be set according to an actual situation.
In some embodiments, the first detection point may be disposed on a Flexible Printed Circuit (FPC) of the NFC antenna, and the second detection point may be disposed on a main board of the mobile terminal. The first detecting point may be a first electrode plate, and the second detecting point may be a second electrode plate. In some embodiments, the first electrode plate and the second electrode plate are equal in area.
It should be noted that, after the FPC of the NFC antenna is enabled, the first electrode plate and the second electrode plate are just opposite to each other, and a capacitor may be formed. It can be understood that the distance between the first detection point and the second detection point is the distance between the first electrode plate and the second electrode plate.
It should be noted that, there are various ways to obtain the distance between the first electrode plate and the second electrode plate, for example, a distance sensor may be disposed in the mobile terminal, and the distance between the two electrode plates is obtained by the distance sensor; for another example, the distance between the first electrode plate and the second electrode plate can be obtained by obtaining a capacitance value between the first electrode plate and the second electrode plate.
Wherein, can predetermine the capacitance value between two electrode boards to be C, the distance is D, the dielectric constant is epsilon, the area of two electrode boards is S, then can be by the capacitance value formula between two electrode boards: and C is equal to epsilon S/D, and the distance D between the two electrode plates is equal to epsilon S/C, wherein epsilon and S are both known quantities. That is, the step of "acquiring the distance between the first detection point disposed on the NFC antenna and the second detection point disposed on the main board of the mobile terminal" may include:
acquiring a capacitance value between the first electrode plate and the second electrode plate;
and acquiring the distance between the first electrode plate and the second electrode plate according to the capacitance value.
The capacitance value between the first electrode plate and the second electrode plate is unknown and needs to be obtained through other methods. For example, it may be preset that the voltage difference between the first electrode plate and the second electrode plate is U, the electric quantity value is Q, the capacitance value is C, and the capacitance value is Q/U.
In some embodiments, the capacitor formed by the first electrode plate and the second electrode plate may be charged, and when the charging is completed, the voltage difference U between the first electrode plate and the second electrode plate may be directly obtained. That is, the step of "obtaining a capacitance value between the first electrode plate and the second electrode plate" may include:
charging the first electrode plate and the second electrode plate;
when charging is completed, acquiring a voltage difference value between the first electrode plate and the second electrode plate;
and acquiring a capacitance value between the first electrode plate and the second electrode plate according to the voltage difference value.
It should be noted that, during the charging process, the voltage difference between the first electrode plate and the second electrode plate may be changed continuously, and when the voltage difference does not change any more for a period of time, the charging process may be considered to be completed. In some embodiments, the voltage difference between the first electrode plate and the second electrode plate may be continuously detected during the charging process; and when the voltage difference value is detected not to change for the preset time, determining that the charging is finished. The preset time may be set according to actual conditions, for example, 1 second, 2 seconds, or 3 seconds.
The step of obtaining the capacitance value between the first electrode plate and the second electrode plate according to the voltage difference value may include:
acquiring an electric quantity value between the first electrode plate and the second electrode plate;
and acquiring a capacitance value between the first electrode plate and the second electrode plate according to the voltage difference value and the electric quantity value.
In some embodiments, an electric quantity obtaining module may be disposed in the mobile terminal, and the first electrode plate and the second electrode plate are connected through a resistor R. In the implementation, a timer for a preset time period t may be set, and the electric quantity Q may be set to zero. After waiting for a preset time period t, acquiring voltage values at two ends of the resistor R, and if the voltage values at two ends of the resistor R are zero, determining that the electric quantity Q is completely acquired; if the voltage values at the two ends of the resistor R are not zero, the voltage values at the two ends of the resistor R can be acquired after waiting for a preset time period. The preset time period t is a very small time interval, for example, 5 microseconds, 10 microseconds, or the like.
The electric quantity value Q is obtained by a basic formula Q ═ It calculated based on the electric quantity value. Because I is the current flowing through the resistor R during the discharge process; as the discharge progresses, the voltage at the two ends of the resistor R is continuously reduced, so that I is also continuously reduced; therefore, it can be considered that the current flowing through the resistor R is constant in a very small time interval (e.g., 10 microseconds); therefore, the step is repeatedly executed until the voltage at the two ends of the resistor R is zero, namely the capacitor finishes discharging; the formula Q ═ It can be adopted for each minimum time interval, and then the electric quantity calculated in each minimum time interval can be accumulated, and the total electric quantity after accumulation is the required electric quantity Q.
It should be noted that the terms "first", "second" and "third" in the description of the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", "third" may explicitly or implicitly include one or more of the described features.
102. And determining whether the distance is smaller than a preset threshold value.
The preset threshold is a maximum threshold that the NFC function can normally use, and the preset thresholds of mobile terminals of different models are generally different.
103. And if the distance is smaller than or equal to the preset threshold value, determining that the NFC function of the mobile terminal is in a normal state.
When the distance between the first electrode plate and the second electrode plate is smaller than or equal to a preset threshold value, the NFC antenna is matched with the mobile terminal, and PFC of the NFC antenna is enabled. The first electrode plate on the FPC of the NFC antenna can be connected with the second electrode plate on the mobile terminal mainboard through an FPC internal lead of the NFC antenna. At this time, the NFC function of the mobile terminal is in a normal state and can be used normally.
In some embodiments, when it is detected that the NFC function of the mobile terminal is normal, a prompt message may be sent by the mobile terminal to prompt the user that the NFC function is normal. For example, the user may set a corresponding prompting ring in the mobile terminal in advance, and when detecting that the NFC function is normal, the mobile terminal may send the prompting ring to prompt the user. It is understood that the prompting message may also be prompted in other forms, such as one or more of vibration, flashing screen, message or ring, and the like, which are not described in detail herein.
104. And if the distance is greater than the preset threshold value, determining that the NFC function of the mobile terminal is in an abnormal state.
When the distance between the first electrode plate and the second electrode plate is larger than a preset threshold value, the NFC antenna is not matched with the mobile terminal, and PFC of the NFC antenna is disabled. The first electrode plate on the FPC of the NFC antenna cannot be connected with the second electrode plate on the mobile terminal mainboard through the FPC internal lead of the NFC antenna. At this time, the NFC function of the mobile terminal is in an abnormal state and cannot be used normally.
In some embodiments, when detecting that the NFC function of the mobile terminal is abnormal, a prompt message may be sent by the mobile terminal to prompt the user that the NFC function is abnormal. For example, the user may set a corresponding prompting ring in the mobile terminal in advance, and when detecting that the NFC function is abnormal, the mobile terminal may send the prompting ring to prompt the user. It is understood that the prompting message may also be prompted in other forms, such as one or more of vibration, flashing screen, message or ring, and the like, which are not described in detail herein. It should be noted that the prompt information indicating that the NFC function is abnormal is different from the prompt information indicating that the NFC function is normal.
The embodiment adopts the steps of obtaining the distance between a first detection point arranged on the NFC antenna and a second detection point arranged on the mobile terminal main board; determining whether the distance is smaller than a preset threshold value; if the distance is smaller than or equal to the preset threshold value, determining that the NFC function of the mobile terminal is in a normal state; and if the distance is greater than the preset threshold value, determining that the NFC function of the mobile terminal is in an abnormal state. According to the scheme, the distance between the first detection point and the second detection point is compared with the preset threshold value, and whether the NFC function is in a normal state or not is determined according to the comparison result; therefore, after the rear cover of the mobile terminal is replaced, whether the NFC antenna in the rear cover is matched with the mobile terminal or not can be accurately judged, and the situation that the NFC function is abnormal after the rear cover of the mobile terminal is replaced is avoided.

Wherein, can predetermine the capacitance value between two electrode boards to be C, the distance is D, the dielectric constant is epsilon, the area of two electrode boards is S, then can be by the capacitance value formula between two electrode boards: and C is equal to epsilon S/D, and the distance D between the two electrode plates is equal to epsilon S/C, wherein epsilon and S are both known quantities.
The capacitance value between the first electrode plate and the second electrode plate is unknown and needs to be obtained through other methods. For example, it may be preset that the voltage difference between the first electrode plate and the second electrode plate is U, the electric quantity value is Q, the capacitance value is C, and the capacitance value is Q/U.

The preset time period t is a very small time interval, for example, 5 microseconds, 10 microseconds, or the like.
The electric quantity value Q is obtained by a basic formula Q ═ It calculated based on the electric quantity value. Because I is the current flowing through the resistor R during the discharge process; as the discharge progresses, the voltage at the two ends of the resistor R is continuously reduced, so that I is also continuously reduced; therefore, it can be considered that the current flowing through the resistor R is constant in a very small time interval (e.g., 10 microseconds); therefore, the step is repeatedly executed until the voltage at the two ends of the resistor R is zero, namely the capacitor finishes discharging; the formula Q ═ It can be adopted for each minimum time interval, and then the electric quantity calculated in each minimum time interval can be accumulated, and the total electric quantity after accumulation is the required electric quantity Q.
