Description
Technical Field
The application relates to the technical field of mobile terminals, in particular to a near field communication antenna detection method and device, a mobile terminal and a storage medium.
Background
Near Field Communication (NFC) is a short-range and high-frequency radio technology that employs active and passive reading modes, and can perform identification and data exchange with compatible devices over short distances. With the maturity of NFC technology, more and more mobile terminals integrate NFC to realize corresponding functions, for example, the mobile terminals may use NFC as airport boarding verification, entrance key of a building, transportation one-card access, credit card, payment card, and the like, which brings great convenience to users.
At present, one of the key points of the NFC technology is that on the antenna, the NFC antenna is often large in area and generally disposed in the rear cover of the mobile terminal, so that the sensing distance of the NFC antenna can be effectively maintained. When the mobile terminal uses the NFC antenna, the NFC antenna which is matched with the mobile terminal needs to be used, the problems of insensitive identification or abnormity and the like are easily caused when the mobile terminal uses a non-standard rear cover, at the moment, the NFC antenna can be mistakenly considered to be damaged, the NFC antenna is maintained or replaced, when the replaced NFC antenna is still matched with the mobile terminal in a non-standard mode, the problems of abnormal NFC function and the like still exist, and great troubles are brought to a user. For example, the back covers of various types of mobile terminals of mobile terminal manufacturers may be the same, but the NFC antennas of the mobile terminals are different, and when a user replaces the back cover in a regular after-sales repair point, a maintenance worker easily replaces the back cover with a back cover that is not the mobile terminal, which still causes the NFC function to be abnormal, so that the user is very inconvenient to use.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the 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.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a method for detecting a nfc antenna according to an embodiment of the present disclosure. The execution main body of the near field communication antenna detection method can be the near field communication antenna detection device provided by the embodiment of the application, or a mobile terminal integrated with the near field communication antenna detection device, wherein the near field communication antenna detection device can be realized in a hardware or software mode, and the mobile terminal can be a smart phone, a tablet computer, a palm computer, a notebook computer or the like. The near field communication antenna detection method may include:
s101, inputting a preset input signal into an input port of a dual-port network corresponding to the NFC antenna.
The NFC antenna detection method can be used for a mobile terminal, the mobile terminal comprises a shell, an NFC antenna is arranged on the shell, for example, the shell of the mobile terminal can comprise a rear cover, the NFC antenna can be arranged on the rear cover of the mobile terminal, a dual-port network is correspondingly arranged on the NFC antenna, the dual-port network is used for detecting the NFC antenna, and the dual-port network can be flexibly arranged according to actual needs. When the number of the NFC antennas is multiple, a corresponding dual-port network may be set for each NFC antenna.
For example, the dual-port network may include an input port, an output port, a ground port, and the like, where the input port is configured to receive a preset input signal, and after the input signal is processed by the dual-port network, the output port may output a parameter corresponding to the processed input signal, and a type of a circuit included in the dual-port network may be flexibly set according to actual needs.
The preset input signal may be a sine wave signal, a square wave signal, a cosine wave signal, a sawtooth wave signal, a triangular wave signal, or a ramp wave signal, and the input signal may be a signal whose frequency changes from small to large and whose amplitude is constant, and may be input to an input port of a dual-port network corresponding to the NFC antenna.
And S102, acquiring output parameters output based on the input signals through the output port of the dual-port network.
After an input signal is input into the dual-port network, the input signal may be processed through the dual-port network, for example, the input signal may be attenuated or filtered through the dual-port network, and then an output parameter output by an output port of the dual-port network based on the input signal after processing is obtained, where the output parameter may be a frequency value or a frequency range, for example, when only an input signal with a frequency of 600kHZ can pass through the dual-port network, the obtained output parameter is 600 kHZ; when an input signal having a frequency of 100kHZ to 1000kHZ can pass through the two-port network, the obtained output parameters are 100kHZ to 1000 kHZ.
S103, judging whether the output parameters are matched with preset standard parameters or not.
The standard configuration parameters can be used for setting a matched NFC antenna for the mobile terminal when the mobile terminal is produced, the use parameters corresponding to the NFC antenna are standard configuration parameters, the mobile terminal can store the standard configuration parameters in advance, and one or more standard configuration parameters can be correspondingly set for one NFC antenna. For example, when the mobile terminal is provided with one NFC antenna, a plurality of calibration parameters may be stored, and the plurality of calibration parameters are the calibration parameters of the NFC antenna; when the mobile terminal is provided with a plurality of NFC antennas, a plurality of calibration parameters may be stored, and each calibration parameter may be a calibration parameter corresponding to each NFC antenna, or each NFC antenna in a part of NFC antennas corresponds to one calibration parameter, and each NFC antenna in another part of NFC antennas corresponds to a plurality of calibration parameters, and the like.
After the output parameter is obtained, it may be determined whether the output parameter matches a pre-stored standard parameter, for example, when the standard parameter is a numerical value, it may be determined whether the output parameter is consistent with the standard parameter, or, when the standard parameter is a numerical value interval, it may be determined whether the output parameter is located in the interval of the standard parameter, and so on.
And S104, if the output parameters are matched with the standard parameters, determining that the NFC antenna is the NFC antenna which is standard for the mobile terminal.

The embodiment of the application can input the preset input signal into the input port of the dual-port network corresponding to the NFC antenna, then the output parameter output based on the input signal through the output port of the dual-port network is obtained, then whether the output parameter is matched with the preset standard matching parameter is judged, and at the moment, if the output parameter is matched with the standard matching parameter, the NFC antenna is determined to be the NFC antenna matched with the mobile terminal. Whether the NFC antenna used currently is a standard antenna or not can be accurately identified by the mobile terminal, so that the problems that the NFC function is abnormal due to the fact that the mobile terminal uses a non-standard NFC antenna and the NFC function is abnormal due to the fact that maintenance personnel mistakenly replace the NFC antenna during maintenance are avoided, convenience and reliability of the mobile terminal for detecting the near field communication antenna are improved, and convenience is brought to users.
The method for detecting an antenna according to the near field communication described in the above embodiments will be described in further detail below by way of example.
Referring to fig. 2, fig. 2 is another schematic flow chart of a method for detecting a nfc antenna according to an embodiment of the present disclosure. The method for detecting the near field communication antenna can be applied to a mobile terminal, and the mobile terminal can comprise a shell, wherein the shell is provided with an NFC antenna, for example, the shell of the mobile terminal can comprise a rear cover, and the NFC antenna can be arranged on the rear cover of the mobile terminal. This NFC antenna correspondence is provided with dual-port network etc. and this dual-port network is used for detecting this NFC antenna, and this dual-port network can carry out nimble setting according to actual need. For example, as shown in fig. 3, the dual-port network may include an input port for receiving an input signal, an output port, a ground port, and the like, wherein the output port may output a parameter corresponding to the processed input signal after the input signal is processed by the dual-port network.
As shown in fig. 2, the flow of the near field communication antenna detection method may be as follows:
s201, generating an input signal with a constant amplitude and a frequency varying from small to large.
The input signal may be a sine wave signal, a square wave signal, a cosine wave signal, a sawtooth wave signal, a triangular wave signal, or a ramp wave signal, the signal generator may generate an input signal with a constant amplitude and a frequency varying from small to large, and the input signal may be input to an input port of a dual-port network corresponding to the NFC antenna.
For example, as shown in fig. 4, the input signal may be a sine wave signal, the amplitudes of the sine wave signals corresponding to fig. 4(a), fig. 4(b), fig. 4(c), and the like are all consistent, that is, the amplitude is constant at the p value, the frequencies corresponding to fig. 4(a), fig. 4(b), fig. 4(c), and the like are changed from small to large, that is, the difference between f1 and f2 is smaller than the difference between f3 and f4, and the difference between f3 and f4 is smaller than the difference between f5 and f6, and the input signal with the constant amplitude and the frequency changed from small to large as shown in fig. 4(a) to fig. 4(c) may be obtained as a second time.
For another example, as shown in fig. 5, the input signal may be a sawtooth wave signal, the amplitudes of the corresponding sawtooth wave signals in fig. 5(a), fig. 5(b), fig. 5(c), and the like are all consistent, that is, the amplitude is constant at a p value, the corresponding frequencies in fig. 5(a), fig. 5(b), fig. 5(c), and the like are changed from small to large, that is, the difference between f1 and f2 is smaller than the difference between f3 and f4, and the difference between f3 and f4 is smaller than the difference between f5 and f6, and the input signal with constant amplitude and changing from small to large according to the frequencies in fig. 5(a) to fig. 5(c) can be obtained.
And S202, inputting the input signal into an input port of the dual-port network corresponding to the NFC antenna.
After the input signal is generated, the input signal can be input into the input port of the dual-port network corresponding to the NFC antenna, and when one NFC antenna needs to be detected, only the input signal needs to be input into the input port of the dual-port network corresponding to the NFC antenna. When a plurality of NFC antennas need to be detected, each NFC antenna may be provided with a corresponding dual-port network, at this time, a plurality of groups of input signals with frequencies varying from small to large and with constant amplitudes may be generated, and each group of input signals is input to the input port of the dual-port network corresponding to each NFC antenna.
And S203, attenuating the input signals in sequence through the dual-port network to obtain attenuated signals.
After the input signal is input into the dual-port network, the input signal may be attenuated by the dual-port network to obtain an attenuated signal, for example, when the input signal is 100kHZ, the input signal may be attenuated by the dual-port network to obtain an attenuated signal of 900kHZ or 800 kHZ.
And S204, obtaining the attenuated signal which is output through the output port of the dual-port network and is larger than a preset threshold value, and obtaining an output parameter.
In the attenuated signals obtained by attenuating the input signals through the dual-port network, only the attenuated signals larger than the preset threshold value can be output through the output port of the dual-port network, and the attenuated signals smaller than or equal to the preset threshold value cannot be output through the output port of the dual-port network. The preset threshold value may be flexibly set according to actual needs, and the signal after attenuation is greater than the preset threshold value, which indicates that the input signal is not attenuated much through the dual-port network, and indicates that the input signal can pass through the dual-port network, for example, the preset threshold value may be set to be 0.8 times or 0.9 times of the amplitude of the input signal.
For example, when only an input signal with a frequency greater than 600kHZ can pass through the dual-port network, the output parameter that can be obtained is greater than 600 kHZ; when an input signal having a frequency of 100kHZ to 1000kHZ can pass through the two-port network, output parameters of 500kHZ to 900kHZ may be acquired, or output parameters of 200kHZ to 800kHZ and the like may be acquired.
Because the obtained output parameter can be a frequency range, input signals with various frequencies (namely input signals with constant amplitude from small to large) can be input, and then, the input signals with which frequencies can be output through the output ports of the dual-port network are judged, so that the output parameter is obtained.
S205, judging whether the output parameters are matched with preset standard parameters or not; if yes, go to step S206; if not, go to step S207.
The standard configuration parameters can be used for setting a matched NFC antenna for the mobile terminal when the mobile terminal is produced, the use parameters corresponding to the NFC antenna are standard configuration parameters, the mobile terminal can store the standard configuration parameters in advance, and one or more standard configuration parameters can be correspondingly set for one NFC antenna. For example, when the mobile terminal is provided with one NFC antenna, a plurality of calibration parameters may be stored, and the plurality of calibration parameters are the calibration parameters of the NFC antenna; when the mobile terminal is provided with a plurality of NFC antennas, a plurality of calibration parameters may be stored, and each calibration parameter may be a calibration parameter corresponding to each NFC antenna, or each NFC antenna in a part of NFC antennas corresponds to one calibration parameter, and each NFC antenna in another part of NFC antennas corresponds to a plurality of calibration parameters, and the like.
For example, when the mobile terminal is produced or retrofitted, if the mobile terminal a is provided with the NFC antenna a, the NFC antenna a is correspondingly provided with the standard configuration parameter a, and at this time, the mobile terminal a may store the standard configuration parameter a in advance; when the mobile terminal B is provided with the NFC antenna B and the NFC antenna C, the NFC antenna B is correspondingly provided with the standard matching parameter B, and the NFC antenna C is correspondingly provided with the standard matching parameter C, the mobile terminal B may pre-store the standard matching parameter B and the matching parameter C; when the mobile terminal C is provided with the NFC antenna D, the NFC antenna D is correspondingly provided with the standard configuration parameter D and the standard configuration parameter E, and at this time, the mobile terminal B may store the standard configuration parameter D and the configuration parameter E in advance; and so on.
In some embodiments, the step of determining whether the output parameter matches the preset calibration parameter may include: judging whether the output parameters are positioned in the frequency interval of the standard parameters; when the output parameters are located in the frequency interval of the standard matching parameters, determining that the output parameters are matched with the standard matching parameters; and when the output parameter is not located in the frequency interval of the standard matching parameter, determining that the output parameter is not matched with the standard matching parameter.
Specifically, after the output parameter is obtained, it may be determined whether the output parameter matches a pre-stored standard matching parameter, for example, when the standard matching parameter is a numerical value, it may be determined whether the output parameter is consistent with the standard matching parameter, and if the output parameter is consistent with the standard matching parameter, it is determined that the output parameter matches the standard matching parameter; and if the output parameters are not consistent with the standard parameters, determining that the output parameters are not matched with the standard parameters. Or, when the standard matching parameter is a numerical value interval, judging whether the output parameter is located in the frequency interval of the standard matching parameter, and when the output parameter is located in the frequency interval of the standard matching parameter, determining that the output parameter is matched with the standard matching parameter; and when the output parameter is not located in the frequency interval of the standard matching parameter, determining that the output parameter is not matched with the standard matching parameter.
In some embodiments, when the calibration parameters include a plurality of parameters, the step of determining whether the output parameters match the preset calibration parameters may include: judging whether the output parameters are matched with a plurality of standard matching parameters or not; when the output parameter is matched with any one of the plurality of calibration parameters, determining that the output parameter is matched with the calibration parameter; when the output parameter does not match any of the plurality of calibration parameters, determining that the output parameter does not match the calibration parameter.
Since the calibration parameters may include a plurality of parameters, the output parameters are determined to match the calibration parameters as long as any one of the plurality of calibration parameters matches the output parameters. For example, the output parameter may be compared with a first one of the plurality of calibration parameters, and when the output parameter matches the first one, it is determined that the output parameter matches the calibration parameter, and at this time, it is not necessary to continue comparing the output parameter with other calibration parameters; when the output parameter is not matched with the first standard matching parameter, the output parameter is compared with the second standard matching parameter, when the output parameter is matched with the second standard matching parameter, the output parameter is determined to be matched with the standard matching parameter, and at the moment, the output parameter does not need to be continuously compared with other standard matching parameters; and when the output parameter is not matched with the second standard matching parameter, comparing the output parameter with the third standard matching parameter, and so on until the output parameter is determined to be matched with one of the standard matching parameters, or until the output parameter is compared with a plurality of standard matching parameters, thereby obtaining a judgment result.
