In some embodiments of the present application, an electronic device is provided, and fig. 1 shows one of the structural block diagrams of the electronic device provided in the embodiments of the present application. As shown in fig. 1, the electronic device 100 includes: a plurality of first antennas 110 and a first controller 120.

The plurality of first antennas 110 are connected in series, the plurality of first antennas 110 are arranged at intervals, and each first antenna 110 can perform card reading detection by receiving and transmitting near field communication signals;

near Field Communication (NFC) is a Near Field Communication technology based on 13.56MHz, and is mainly used in scenes such as user access cards, traffic cards, attendance cards, identity cards and the like.

The first controller 120 is connected to the plurality of first antennas 110, and the first controller 120 is configured to obtain voltage signals of the plurality of first antennas 110;

and under the condition that the signal value variation of the voltage signal is greater than the preset variation, controlling the plurality of first antennas 110 to perform card reading detection and human body detection.

In the embodiment of the present application, the plurality of first antennas 110 are connected in series to form an equivalent antenna. When the metal equivalent is close to or far from one or more of the first antennas 110, the inductance value and the capacitance value of the close or far first antenna 110 are changed, and the corresponding inductance value and capacitance value of the whole equivalent antenna are changed, so that the signal value of the voltage signal at the whole equivalent antenna is changed. Therefore, when the detected signal value variation of the voltage signal is greater than the preset variation, it can be determined that a metal equivalent is close to or away from the plurality of first antennas 110, that is, a human body or an NFC (Near Field Communication) identification card is detected to be close to, and at this time, the plurality of first antennas 110 are controlled to perform card reading detection and human body detection synchronously, so as to determine whether the human body is close to or away from the plurality of first antennas 110 or the NFC identification card is close to the plurality of first antennas 110.

The first antenna 110 is an antenna capable of transceiving near field communication signals. When detecting that a metal equivalent is close to or far from the plurality of first antennas 110, the first controller 120 attempts to wake up the metal equivalent by controlling the plurality of first antennas 110 to read a card, and when the wake-up is successful, the close metal equivalent can be determined to be an NFC card, and when the wake-up is failed, the close metal equivalent can be determined to be a human body, so that whether the human body is close to or far away from the NFC identification card can be detected. In the embodiment of the present application, the plurality of first antennas 110 are provided at intervals, so that the plurality of first antennas 110 can be distributed at intervals inside the electronic device 100.

In the process of performing NFC card reading detection and human body detection by a user, the metal equivalent can be detected and identified by the electronic device 100 from which direction the metal equivalent is close to or away from the electronic device 100, so that the detection performance of NFC is improved, and the situation that the card reading of the NFC identification card is invalid due to the fact that the NFC identification card is close to the electronic device 100 from a certain position is avoided.

Illustratively, the first antennas 110 are antennas obtained by designing coils on a Flexible Printed Circuit Board (FPC), each of the first antennas 110 includes two terminals, ANT + (Antenna +, positive Antenna) and ANT- (Antenna-, negative Antenna), and the plurality of first antennas 110 are connected in series by ANT + and ANT-in sequence. Specifically, the ANT + of one first antenna 110 of the adjacent two first antennas 110 is connected to the ANT-of the other first antenna 110.

Fig. 3 shows one of the circuit diagrams of the electronic device 100 provided in the embodiment of the present application, and as shown in fig. 3, the electronic device 100 includes an application processor 140, an NFC chip 130, an antenna matching circuit 150, and a plurality of first antennas 110 connected in series. Wherein the first controller 120 is disposed in the NFC chip 130. The NFC chip 130 is an integrated circuit, and the NFC chip 130 includes the first controller 120 and the radio frequency modem, and can control the multiple first antennas 110 to perform human body detection and card reading detection, so as to accurately detect a metal equivalent, for example: human body, NFC identification card, metal, etc. The antenna matching circuit 150 is disposed between the NFC chip 130 and the plurality of first antennas 110, and the antenna matching circuit 150 includes a passive device required by the first antennas 110, so that the plurality of first antennas 110 can normally transmit signals. The application processor 140 is a process in the electronic device 100 that is responsible for software system operation, mobile phone terminal function timing, and control of peripheral devices. The first controller 120 in the NFC chip 130 can transmit the collected information to the application processor 140 for uniform processing.

According to the embodiment of the application, the plurality of first antennas 110 are arranged in series, and the first controller 120 is used for detecting the signal value variation of the voltage signal of the equivalent antenna formed by the series connection of the plurality of first antennas 110, so that the human body detection and the NFC card reading detection can be synchronously performed, hardware such as a sensor for performing the human body detection does not need to be independently installed in the electronic device 100, the manufacturing cost of the electronic device 100 is reduced, and the internal space of the electronic device 100 is saved.

According to the embodiment of the application, the human body detection is performed on the plurality of first antennas 110 with the NFC identification function, no additional human body detection hardware is arranged, the interference influence caused by hardware between NFC card reading detection and human body detection is fundamentally avoided, and the hardware design is simplified.

In some embodiments of the present application, the first controller 120 controls the plurality of first antennas 110 to perform card reading detection and human body detection based on that the signal value variation of the voltage signal is greater than a preset variation, including: determining that the distance between the target human body and the electronic device 100 is out of a preset distance range under the condition that the plurality of first antennas 110 read the target identification card; in a case where the plurality of first antennas 110 do not read the target identification card, it is determined that the distance between the target human body and the electronic apparatus 100 is within a preset distance range.

In the embodiment of the present application, the target identification card may be an NFC identification card matched with the plurality of first antennas 110. Illustratively, when the first controller 120 detects that the metal equivalent is approaching or moving away from the electronic device 100 through the plurality of first antennas 110, the first controller 120 periodically sends out different card reading detection signals through the plurality of first antennas 110, and the first controller 120 sequentially sends out the card reading detection signals of the four protocols of ISO14443A protocol, ISO14443B protocol, ISO18902 Felica protocol and ISO15693 through the plurality of first antennas 110 during the card reading process. In case of an NFC card being close, the electronic device 100 is able to receive a corresponding reply signal.

The first controller 120 determines that there is a metal equivalent approaching or departing from the electronic device 100 by the amount of change in the signal value of the voltage signal. The first controller 120 controls the plurality of first antennas 110 to transmit a card reading detection signal, detects whether a target identification card approaches the electronic device 100, and determines that the electronic device 100 needs to read a card at this time and determines that a human body does not approach the electronic device 100 at this time when it is detected that the target identification card approaches the electronic device 100. In the case where it is detected that the target identification card does not approach the electronic apparatus 100, it is determined that a human body approaches the electronic apparatus 100 at this time.

In the embodiment of the present application, when the first controller 120 determines that a metal equivalent is close to or far from the electronic device 100, the first antennas 110 are controlled to send a card reading detection signal, so as to execute a complete card reading detection process, and detect whether the metal equivalent is a target identification card. In the case where it is determined that the metal equivalent is not the target identification card, the first controller 120 reads the target identification card, and in the case where it is determined that the metal equivalent is not the target identification card, it is determined that the human body approaches or moves away from the electronic device 100. Under the condition that the first controller 120 detects that the metal equivalent is close to or far away from the electronic device 100, the card reading detection signals are sent through the plurality of first antennas 110, so that whether the metal equivalent is a target identification card or not can be accurately judged, and whether a human body is close to or far away from the electronic device 100 or not can be determined according to the card reading detection signals, so that card reading detection and human body detection are performed synchronously, and the human body detection function is realized while card reading detection accuracy is ensured.

In some embodiments of the present application, the antenna parameters of the plurality of first antennas 110 are different, the antenna parameters including at least one of: size of coil, inductance value, capacitance value.

The electronic device 100 further comprises: a plurality of second antennas 160. The plurality of second antennas 160 are connected to the first controller 120, and the plurality of second antennas 160 correspond to the plurality of first antennas 110 one to one.

The first controller 120, after determining that the distance between the target human body and the electronic device 100 is within the preset distance range under the condition that the plurality of first antennas 110 do not read the target identification card, further includes: and under the condition that the distance between the target human body and the electronic device 100 is within the preset distance range, controlling the target antenna in the plurality of second antennas 160 to perform down-conversion operation according to the signal value of the voltage signal.

In the embodiment of the present application, the plurality of first antennas 110 are connected in series to form an equivalent antenna, and when the metal equivalent is close to or far from different first antennas 110 in the plurality of first antennas 110 under the condition that the antenna parameters of the plurality of first antennas 110 are different, the signal value variation of the voltage signal at the plurality of first antennas 110 is different. After determining that the metal equivalent approaching or departing from the electronic device 100 is a human body, the first controller 120 can determine the approaching or departing direction of the human body according to the signal values of the voltage signals of the plurality of first antennas 110.

Specifically, the inductance L and the capacitance C of the plurality of first antennas 110 are significantly different. The number of the first antennas 110 is 3, which are an antenna a, an antenna B, and an antenna C, respectively. The L1, C1 of the antenna A is much smaller than the L2, C2 of the antenna B, and the L2, C2 of the antenna B is much smaller than the L3, C3 of the antenna C. When a human body approaches to the antenna a, the antenna B, and the antenna C, detuning ranges of equivalent antennas of the antenna a, the antenna B, and the antenna C are different, for example: the detuning range of the equivalent antenna is 2% -8% when the equivalent antenna is close to the antenna A, 10% -18% when the equivalent antenna is close to the antenna B, and 20% -28% when the equivalent antenna is close to the antenna C. Therefore, when a human body approaches or moves away from different antennas of the plurality of first antennas 110, the signal value variation amounts of the voltage signals at the plurality of first antennas 110 are different, and which one of the plurality of first antennas 110 the human body approaches can be determined according to the signal values, thereby determining the direction in which the human body approaches the electronic device 100.

The antenna parameters of the first antenna 110 may include at least one of a size, an inductance value and a capacitance value of the coil, and when a target object is close to or far from the first antenna 110, the inductance value and the capacitance value of the close first antenna 110 are changed, so that the inductance value and the capacitance value of the total equivalent antenna are changed.

In the embodiment of the present application, by setting the antenna parameters of the first antenna 110 to include at least one of the size, the inductance value, and the capacitance value of the coil, it is achieved that, when the metal equivalent is close to the plurality of first antennas 110, the capacitance value and the inductance value of the equivalent antenna of the plurality of first antennas 110 are changed accordingly, so that the signal value of the voltage signal at the plurality of first antennas 110 is changed accordingly, and accurate detection of whether the metal equivalent is close to or away from the electronic device 100 is achieved.

In this embodiment, the electronic device 100 further includes a plurality of second antennas 160, the number of the second antennas 160 is the same as the number of the first antennas 110, and the setting position of the second antennas 160 is adjacent to the setting position of the first antennas 110, that is, the second antennas 160 and the first antennas 110 are arranged in a one-to-one correspondence manner. The plurality of second antennas 160 are rf antennas for transceiving rf signals, and the electronic device 100 transmits the rf signals through the second antennas 160 for communication during the wireless communication process. When detecting that the human body approaches or leaves a certain first antenna 110 of the plurality of first antennas 110, the second antenna 160 corresponding to the first antenna 110 is controlled to perform down-conversion operation, so as to avoid the influence of an excessively high operating frequency of the second antenna 160 on the human body.

Fig. 4 shows a second structural schematic diagram of the electronic device 100 according to the embodiment of the present application, and as shown in fig. 4, the number of the first antennas 110 and the number of the second antennas 160 are both 3, 3 first antennas 110 are distributed at intervals on the inner peripheral side of the electronic device 100, and 3 second antennas 160 and 3 first antennas 110 are adjacently disposed in a one-to-one correspondence manner.

Fig. 5 shows a second circuit diagram of the electronic device 100 according to the embodiment of the application, as shown in fig. 5, the electronic device 100 includes an application processor 140, an NFC chip 130, an antenna matching circuit 150, and a plurality of first antennas 110 connected in series. The coils of the plurality of first antennas 110 are different in size.

Fig. 6 shows a graph of the distance between the metal equivalent and the first antenna 110 and the voltage value at the first antenna 110, as shown in fig. 6, the number of the first antennas 110 is 3, namely, the first antenna a, the first antenna B and the first antenna C. Due to the fact that the antenna parameters of the antenna A, the antenna B and the antenna C are different, the antenna A, the antenna B and the antenna C correspond to different voltage value ranges respectively, namely a voltage value range A, a voltage value range B and a voltage value range C. The voltage value range A and the voltage value range B have intersection, and the voltage value range B and the voltage value range C have intersection. When the voltage value of the first antenna 110 is detected to be in the voltage value range a, it is determined that the human body approaches the antenna a, at this time, the second antenna 160 corresponding to the antenna a is controlled to perform down-conversion operation, and when the voltage value of the first antenna 110 is detected to be in the intersection of the voltage value range B and the voltage value range C, the two second antennas 160 corresponding to the antenna B and the antenna C are controlled to perform down-conversion operation. The accurate detection of the direction of the human body approaching to or departing from the electronic device 100 is realized, and the accurate down-conversion control is performed on the corresponding second antenna 160 based on the detected direction, so that the accuracy of the control is further improved.

Illustratively, when detecting that a human body is close to the electronic device 100, the corresponding second antenna 160 is controlled to perform down-frequency operation, and when detecting that a human body is far away from the electronic device 100, the corresponding second antenna 160 is controlled to resume the original frequency operation. Specifically, it is determined that the human body is close to the electronic device 100 or away from the electronic device 100 according to the variation trend of the signal value of the voltage signal, and when the signal value of the voltage signal is detected to be changed from small to large, it is determined that the human body is close to the electronic device 100, and when the signal value of the voltage signal is detected to be changed from large to small, it is determined that the human body is away from the electronic device 100.

Illustratively, when the distance between the human body and the electronic device 100 is detected to be within the preset range, the corresponding second antenna 160 is controlled to perform down-frequency operation, and when the distance between the human body and the electronic device 100 is detected to be outside the preset range, the corresponding second antenna 160 is controlled to perform operation at the original frequency. Specifically, the relative distance between the human body and the plurality of first antennas 110 is determined according to the signal value of the voltage signal, and the corresponding second antenna 160 is controlled to perform down-conversion operation when the relative distance is within a preset range, and the corresponding second antenna 160 is controlled to perform operation at the original frequency when the relative distance is outside the preset range.

In the embodiment of the present application, the antenna parameters of the plurality of first antennas 110 are different, so that the corresponding voltage value ranges are different, and thus which first antenna 110 is the first antenna 110 close to or far away from the human body can be accurately determined according to the signal value of the voltage signal, thereby realizing the distinguishing of the direction in which the human body is close to the electronic device 100. And according to the direction of the human body approaching the electronic device 100, the second antenna 160 approaching the direction is determined as the target antenna, and the target antenna is controlled to perform the frequency reduction operation, so that the accuracy of controlling the frequency reduction operation of the second antenna 160 is improved.

In the embodiment of the present application, since the antenna parameters of the plurality of first antennas 110 are set differently, when the metal equivalent is at different distances from different first antennas 110, the signal values of the voltage signals at the equivalent antennas corresponding to all the plurality of first antennas 110 are different, and therefore, the absolute distance between the metal equivalent and the electronic device 100 can be estimated by presetting and calibrating in advance.

Note that, the signal values of the voltage signals corresponding to different first antennas 110 in the plurality of first antennas 110, which are close to the metal equivalent, are calibrated before the electronic device 100 is shipped.

In some embodiments of the present application, the antenna parameters of the plurality of first antennas 110 are the same.

In the embodiment of the present application, when it is detected that the human body approaches or moves away from the electronic device 100, the plurality of second antennas 160 are controlled to synchronously perform the down-conversion operation. The arrangement positions of the plurality of second antennas 160 are not particularly limited in the arrangement in which the antenna parameters of the plurality of first antennas 110 are the same. Since the antenna parameters of different antennas in the plurality of first antennas 110 are the same, when the metal equivalent is close to different first antennas 110, the signal values of the voltage signals of the equivalent antennas of the plurality of first antennas 110 are similar, and at this time, in order to prevent the radio frequency signal of the second antenna 160 from affecting the human body, the frequency reduction operation is performed on all the second antennas 160.

In some embodiments of the present application, the electronic device 100 further comprises an antenna matching circuit 150. The first terminal and the second terminal of the antenna matching circuit 150 are connected to the first controller 120 and the plurality of first antennas 110, respectively. The antenna matching circuit 150 includes passive components required by the first antenna 110, so that the plurality of first antennas 110 can transmit signals normally.

and under the condition that the target identification cards are not read by the plurality of first antennas, determining that the distance between the target human body and the electronic equipment is within a preset distance range.

And controlling the plurality of first antennas to send card reading detection signals, detecting whether a target identification card approaches the electronic equipment, judging that the electronic equipment needs to read the card at the moment when the target identification card approaches the electronic equipment, and determining that the human body does not approach the electronic equipment at the moment. And under the condition that the target identification card is not close to the electronic equipment, determining that the human body is close to the electronic equipment at the moment.

The target identification card may be an NFC identification card that matches the plurality of first antennas. Illustratively, when the approach or the departure of the electronic equipment from the metal equivalent is detected through the plurality of first antennas, different card reading detection signals are periodically sent out through the plurality of first antennas, and card reading detection signals of the four protocols of the ISO14443A protocol, the ISO14443B protocol, the ISO18902 Felia protocol and the ISO15693 are sequentially sent out through the plurality of first antennas during card reading.

The antenna parameters of the first antenna may include at least one of a size, an inductance value and a capacitance value of the coil, and when a target object approaches or leaves the first antenna, the inductance value and the capacitance value of the first antenna that is approached may be changed, so that the inductance value and the capacitance value of the total equivalent antenna may be changed.

In the embodiment of the application, the antenna parameters of the first antenna are set to at least one of the size, the inductance value and the capacitance value of the coil, so that under the condition that the metal equivalent is close to the plurality of first antennas, the capacitance value and the inductance value of the equivalent antenna of the plurality of first antennas are changed accordingly, the signal value of the voltage signal at the plurality of first antennas is changed accordingly, and whether the metal equivalent is close to or away from the electronic device is accurately detected.

The electronic equipment further comprises a plurality of second antennas, the number of the second antennas is the same as that of the first antennas, and the setting positions of the second antennas are adjacent to that of the first antennas, namely, the second antennas and the first antennas are arranged in a one-to-one correspondence mode. The plurality of second antennas are radio frequency antennas and are used for receiving and transmitting radio frequency signals, and the electronic equipment transmits the radio frequency signals through the second antennas to carry out communication in the wireless communication process. When the human body is detected to be close to or far away from one of the first antennas, the second antenna corresponding to the first antenna is controlled to carry out frequency reduction operation, and the influence of overhigh operation frequency of the second antenna on the human body is avoided.

Under the condition that the target identification card is not read by the plurality of first antennas, after the distance between the target human body and the electronic device is determined to be within a preset distance range, the method further comprises the following steps:

and controlling a target antenna in the plurality of second antennas to perform frequency reduction operation according to the signal value of the voltage signal.

In the embodiment of the application, the plurality of first antennas are connected in series to form an equivalent antenna, and under the condition that the antenna parameters of the plurality of first antennas are different, when the metal equivalent is close to or far away from different first antennas in the plurality of first antennas, the signal value variation of the voltage signals at the plurality of first antennas is different. Therefore, after the metal equivalent approaching or departing from the electronic equipment is determined to be the human body, the approaching or departing direction of the human body can be determined according to the signal values of the plurality of first antenna voltage signals.

Specifically, the inductance L and the capacitance C of the plurality of first antennas are significantly different. The number of the first antennas is 3, which are respectively an antenna A, an antenna B and an antenna C. The L1, C1 of the antenna A is far smaller than the L2, C2 of the antenna B, and the L2, C2 of the antenna B is far smaller than the L3, C3 of the antenna C. When a human body approaches to the antenna a, the antenna B, and the antenna C, detuning ranges of equivalent antennas of the antenna a, the antenna B, and the antenna C are different, for example: the detuning range of the equivalent antenna is 2% -8% when the equivalent antenna is close to the antenna A, 10% -18% when the equivalent antenna is close to the antenna B, and 20% -28% when the equivalent antenna is close to the antenna C. Therefore, when the human body approaches or leaves different antennas of the plurality of first antennas, the signal value variation amounts of the voltage signals at the plurality of first antennas are different, and which of the plurality of first antennas the human body approaches can be determined according to the signal values, so that the direction of the human body approaching the electronic device is determined.

Illustratively, when the human body is detected to be close to the electronic equipment, the corresponding second antenna is controlled to perform frequency reduction operation, and when the human body is detected to be far away from the electronic equipment, the corresponding second antenna is controlled to recover the frequency operation. Specifically, whether the human body is close to the electronic equipment or is far away from the electronic equipment is judged according to the change trend of the signal value of the voltage signal, when the signal value of the voltage signal is detected to be changed from small to large, the fact that the human body is close to the electronic equipment is determined, and when the signal value of the voltage signal is detected to be changed from large to small, the fact that the human body is far away from the electronic equipment is determined.

Exemplarily, when the distance between the human body and the electronic device is detected to be within a preset range, the corresponding second antenna is controlled to perform down-frequency operation, and when the distance between the human body and the electronic device is detected to be outside the preset range, the corresponding second antenna is controlled to perform operation at the original frequency. Specifically, the relative distances between the human body and the plurality of first antennas are determined according to the signal values of the voltage signals, the corresponding second antennas are controlled to perform frequency reduction operation under the condition that the relative distances are within a preset range, and the corresponding second antennas are controlled to perform operation at the original frequency under the condition that the relative distances are outside the preset range.

And according to the direction of the human body approaching the electronic equipment, the second antenna approaching the direction is determined as the target antenna, and the target antenna is controlled to perform frequency reduction operation, so that the accuracy of controlling the frequency reduction operation of the second antenna is improved.

In the embodiment of the application, since the antenna parameters among the plurality of first antennas are set in a differentiated manner, when the metal equivalent is at different distances from different first antennas, the signal values of the voltage signals at the equivalent antennas corresponding to the plurality of first antennas are different, and therefore, the absolute distance between the metal equivalent and the electronic device can be estimated by presetting and calibrating in advance.

It should be noted that, when the metal equivalent is close to the signal value of the voltage signal corresponding to different first antennas in the plurality of first antennas, calibration is performed before the electronic device is shipped.

In some embodiments of the present application, controlling a target antenna of the plurality of second antennas to operate down according to a signal value of the voltage signal includes:

determining a target signal value range in a plurality of signal value ranges according to the signal value of the voltage signal, wherein the signal value of the voltage signal is within the target signal value range, and the plurality of signal value ranges are in one-to-one correspondence with the plurality of second antennas; and controlling the target antenna to perform frequency reduction operation, wherein the target antenna corresponds to the target signal value range.

In the embodiment of the present application, the plurality of signal value ranges correspond to the plurality of first antennas one by one, and the signal value ranges of the corresponding voltage signals are different because the antenna parameters of different first antennas are different. Before the electronic equipment leaves a factory, calibrating the signal value range of the voltage signal corresponding to the approach or the distance of the metal equivalent relative to different first antennas to obtain the signal value range corresponding to the first antennas one by one.

After the signal values of the voltage signals of the plurality of first antennas are acquired, a signal value range in which the signal values are located is determined as a target signal value range.

The number of target signal value ranges may be plural. And an intersection exists between two adjacent signal value ranges in the plurality of signal value ranges corresponding to the plurality of first antennas. If the signal value is in the intersection of two signal value ranges, both signal value ranges are taken as target signal ranges.

After the target signal range is determined, the plurality of signal ranges, the plurality of first antennas and the plurality of second antennas are in one-to-one correspondence, so that the corresponding first antennas and the corresponding target antennas in the plurality of second antennas can be determined according to the target signal range, and the target antennas are controlled to perform frequency reduction operation. And under the condition that the target signal range is two adjacent signal ranges, controlling the two corresponding target antennas to perform frequency reduction operation.

Under the condition that the target signal value ranges are multiple, the operating frequencies of the corresponding second antennas are synchronously reduced, and the stability of controlling the frequency reduction operation of the second antennas is further improved.

In some embodiments of the present application, obtaining voltage signals for a plurality of first antennas comprises:

voltage signals at the plurality of first antennas are collected while the target application is in an operational state, the target application being associated with card reading detection.

In this embodiment of the application, the target application is an application program that needs to read the NFC card, for example: access control applications, bus card applications, and the like. When the electronic equipment runs the target application, the fact that the user possibly has the card reading detection requirement at the moment is judged.

When the target application is in a non-running state, the electronic device judges that the user does not need to read the NFC identification card at the moment, and judges that the metal equivalent approaching or far away from the electronic device is a human body.

And the user starts the functions of card reading detection and human body detection to set based on the target application. Under the condition that a user sets the electronic equipment to continuously start card reading detection, the electronic equipment is always in a state of waiting for the NFC identification card to approach, namely, the card reading is carried out through a corresponding protocol every time the metal equivalent is detected to approach or be far away from the electronic equipment, and the metal equivalent is determined to be a human body if the card reading fails. When a user sets that the electronic equipment starts the target application and then starts card reading detection, the electronic equipment executes the card reading detection only under the condition that the target application is operated, and when the target application is not operated, the electronic equipment directly judges that a human body is close to or far from the electronic equipment if a metal equivalent is detected to be close to or far from the electronic equipment.
