At present, electronic devices such as mobile phones at home and abroad need to meet the SAR (specific absorption rate) in compliance in order to protect the health and safety of human bodies.

However, if the sensing control chip or a detection channel connecting the sensing control chip and the proximity sensing device fails, effective detection of approach of a human body cannot be realized, and effective power control cannot be realized when the human body approaches, which results in that the SAR exceeds the standard.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art based on the embodiments of the present invention without inventive step, are within the scope of the present invention.

In the description of the embodiments of the present invention, it should be understood that the terms "upper", "lower", "thickness", "width", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not imply or indicate that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

Please refer to fig. 1, which is a block diagram of an electronic device 100 according to an embodiment of the present application. As shown in fig. 1, the electronic device 100 includes a proximity sensing module 1, a processor 2, and a plurality of antenna radiators. The proximity sensing module includes a plurality of sensing elements 11, a sensing controller 12, and a plurality of detection channels 121. The plurality of sensing elements 11 are disposed at different positions of the electronic device 100, and each sensing element 11 corresponds to at least one antenna radiator 3; the sensing controller 12 is connected to the plurality of sensing elements through the plurality of sensing channels 121, wherein each sensing channel 121 is connected to at least one sensing element 11. The processor 2 is configured to determine, when the proximity sensing module 1 fails, a target antenna radiator 3 affected by the failure, and control to reduce the operating power of the target antenna radiator 3 to a target operating power.

Thereby, in this application, detecting when being close response module 1 and breaking down, confirm earlier the target antenna irradiator 3 that the trouble influences, and control will target antenna irradiator 3's operating power reduces to target operating power, thereby, even because be close response module 1's trouble leads to target antenna irradiator to correspond the position and can't go to listen whether the human body is close to, then will target antenna irradiator 3's operating power reduces to target operating power, has ensured that SAR accords with the safety regulation requirement, has avoided the radiation hazard to the people.

The target working power can be the maximum power value on the premise that the SAR meets the safety regulation requirement, so that the radiation performance of the antenna is ensured as much as possible. Obviously, the target working power may also be smaller than the maximum power value on the premise that the SAR meets the safety requirements.

Specifically, in the present application, each sensing element 11 is used for generating a sensing signal when sensing the approach of a human body. The sensing controller 12 is connected to the sensing elements 11 through the detection channel 121, and the sensing controller 12 is configured to generate proximity sensing data when receiving a sensing signal generated by the sensing element 11, and report the proximity sensing data to the processor 2. The processor 2 is connected to the sensing controller 12, and configured to receive the proximity sensing data, determine that a human body approaches, and perform corresponding proximity sensing control according to the proximity sensing data. Namely, the proximity sensing module 1 can realize the proximity sensing of the human body and perform corresponding proximity sensing control.

The target antenna radiator 3 affected by the fault refers to the antenna radiator 3 disposed at a position where a human body cannot be detected when a human body cannot be detected at some positions of the electronic device 100 due to a fault at some parts of the proximity sensing module 1, which will be described in more detail later.

In some embodiments, the failure of the proximity sensing module 1 includes at least one of a sensing controller failure, a detection channel failure, and a sensing element failure, wherein the processor 2 determines that all the antenna radiators 3 are target antenna radiators affected by the failure when it is determined that the sensing controller failure occurs. When determining that a detection channel fault occurs, the processor 2 determines that an antenna radiator 3 corresponding to at least one sensing element 11 connected to the detection channel 121 with the fault occurs is a target antenna radiator 3 affected by the fault. When determining that a fault occurs in the sensing element 11, the processor 2 determines that the antenna radiator 3 corresponding to the sensing element 11 with the fault is the target antenna radiator 3 affected by the fault.

That is, when the sensing controller fails, the sensing controller 12 cannot work, so that any proximity sensing data cannot be reported to the processor 2, and at this time, no human proximity sensing can be performed at any position, and thus, all the antenna radiators 3 are affected target antenna radiators. The sensing controller fault may be caused by poor pin soldering of the sensing controller 12, damage to a chip of the sensing controller 12, or the like.

When a detection channel fails, only the detection channel 121 that has failed cannot transmit a sensing signal generated by the at least one sensing element 11 connected to the detection channel 121 to the sensing controller 12, so that the position corresponding to the at least one sensing element 11 connected to the detection channel 121 is a position where a human body cannot be detected, and correspondingly, the antenna radiator 3 corresponding to the at least one sensing element 11 connected to the detection channel 121 is the target antenna radiator 3 affected by the failure.

When a failure occurs in the sensing element 11, only the failed sensing element 11 cannot generate a sensing signal or cannot accurately respond to the approach of a human body to generate an accurate sensing signal, so that only the position corresponding to the failed sensing element 11 is a position at which the approach of a human body cannot be detected, and therefore, only the antenna radiator 3 corresponding to the failed sensing element 11 is the target antenna radiator 3 affected by the failure.

In some embodiments, the sensing controller 12 is further configured to report status information to the processor 2 at each reporting time point periodically according to a preset reporting period, and the processor 2 determines that a sensing controller fault occurs when the reporting status information is not received at least one reporting time point. Specifically, the processor 2 may periodically receive the status information reported by the sensing controller at each reporting time point according to a preset reporting period; and when the processor does not receive the reported state information at least one reporting time point, determining that the induction controller fails.

That is, the sensing controller 12 has two reporting trigger mechanisms, generates proximity sensing data when receiving a sensing signal, and reports the proximity sensing data to the processor 2, and also periodically reports status information to the processor 2 at each reporting time point according to a preset reporting period. In some embodiments, the status information has an identification bit for identifying that the status information is periodically reported status information and is not proximity sensing data.

Therefore, when the processor 2 does not receive the reporting status information at least one reporting time point, it indicates that the sensing controller 12 has a fault and cannot report information, thereby determining that a sensing controller fault has occurred.

The reporting period may be preset as needed, for example, may be 10 seconds, 15 seconds, and the like.

In some embodiments, when the processor 2 does not receive the reported status information at least one reporting time point, it also periodically queries whether there is status information reported by the sensing controller 12 in a preset query period, and confirms that the sensing controller fails to perform the detection only when the processor does not query the status information reported by the sensing controller 12 for a preset number of times. The preset query period is less than the preset reporting period, and may be, for example, half, 1/3, and the like of the preset reporting period.

The state information includes a plurality of pieces of channel information respectively corresponding to the plurality of detection channels 121, each piece of channel information includes identity information of the corresponding detection channel 121 and information indicating whether the corresponding detection channel 121 is normal, the processor 2 receives the state information at an alarm time point, determines that a detection channel fault occurs when at least one piece of channel information in at least one piece of state information indicates that the corresponding at least one detection channel 121 is abnormal, and determines that the abnormal at least one detection channel 121 is the detection channel 121 with the fault.

That is, in some embodiments, each channel information includes identity information of the corresponding detection channel 121 and information indicating whether the corresponding detection channel 121 is normal, the processor 2 receives the status information at the reporting time point, which indicates that the sensing controller 12 is normal, but if at least one channel information in the at least one status information indicates that the corresponding at least one detection channel 121 is abnormal, it indicates that a detection channel fault occurs, and the abnormal at least one detection channel 121 is the faulty detection channel 121.

In some embodiments, when the sensing signal generated by a certain detection channel 121 exceeds a normal range, or the sensing signal generated by the detection channel 121 is not received within a preset time, the sensing controller 12 determines that the detection channel 121 is abnormal, and indicates that the detection channel 121 is abnormal in the channel information corresponding to the next reported state information. Wherein, the processor 2 correspondingly determines that a detection channel fault occurs when at least one channel information in the at least one time status information indicates that the corresponding at least one detection channel is abnormal; and determining at least one detection channel of the abnormality as a detection channel with a fault.

Specifically, the status information may include a plurality of channel indicators, each channel indicator includes an identifier of the detection channel 121 and a status indicator for indicating whether the corresponding detection channel 121 is normal, the processor 2 receives the status information at the reporting time point, and when at least one channel indicator in at least one piece of status information indicates that the corresponding at least one detection channel is abnormal, it determines that a detection channel fault occurs, and determines that the abnormal at least one detection channel 121 is the detection channel 121 with the fault. When the sensing signal generated by a certain detection channel exceeds the normal range or the sensing signal generated by the detection channel is not received within the preset time, the sensing controller 12 determines that the detection channel 121 is abnormal, and changes the state identifier of the corresponding channel indication identifier into an identifier indicating the abnormality in the state information reported next time, thereby indicating that the detection channel 121 is abnormal in the corresponding channel information of the state information reported next time. Correspondingly, the sensing controller 12 receives the sensing signal generated by the detection channel within a preset time, and the sensing signal generated by the detection channel is within a normal range, so as to determine that the detection channel 121 is normal.

The sensing element 11 is a metal conductive element, and a human body is also a conductor, when a human body approaches at least one sensing element 11, a coupling capacitance is generated with the at least one sensing element, so that a charge of the at least one sensing element 11 is changed, and the sensing signal is generated, and the sensing signal may be a current signal or a voltage signal. In some embodiments, the sensing signal may also be a charge variation value. The occurrence of an anomaly in a certain detection channel 121 may include: the electrical parameters of the detection channel 121, such as inductance and resistance, are abnormal, which results in the sensing signal exceeding the normal range, or the sensing channel 121 is disconnected and cannot transmit the sensing signal. Therefore, when the sensing signal generated by a certain detection channel 121 exceeds a normal range or the sensing signal generated by the detection channel 121 is not received within a preset time, the sensing controller 12 determines that the detection channel 121 is abnormal.

The preset time may be much longer than the reporting period of the sensing controller 12, and may be set according to a usage habit of a user of the electronic device 100, for example, an average time interval between two adjacent times of the user and the electronic device 100 is determined according to a historical usage record of the user of the electronic device 100, and then, a time duration less than or equal to the average time interval is set as the preset time. For example, the preset time may be 10 minutes, 15 minutes, and the like.

When the sensing controller 12 is not faulty, i.e. normal, the normal sensing element 11 can generate a sensing signal when sensing the approach of a human body for the normal detection channel 121 and the normal sensing element. When the sensing controller 12 receives the sensing signal generated by the sensing element 11 through the normal detection channel 121, it generates proximity sensing data and reports the proximity sensing data to the processor 2. The processor 2 is connected to the sensing controller 12, and is configured to receive the proximity sensing data, determine that a human body is approaching, and perform proximity sensing control, for example, control to reduce the power of the antenna radiator 3 at a corresponding position. In other words, normal human body proximity sensing can be realized, and normal antenna power control can be performed.

In some embodiments, some or all of the plurality of inductive elements 11 are antenna radiators 3, that is, in some embodiments, some or all of the inductive elements 11 are multiplexed with the antenna radiators 3 originally included in the electronic device 100.

In some embodiments, when the at least one sensing element 11 connected to the detection channel 121 with the fault is the antenna radiator 3, the processor 2 determines that the at least one sensing element 11 connected to the detection channel with the fault is the target antenna radiator 3 affected by the fault when determining that the detection channel fault occurs, and the processor 2 determines that the sensing element 11 with the fault is the target antenna radiator 3 affected by the fault when determining that the sensing element fault occurs.

As shown in fig. 1, the electronic device 100 further includes a memory 4, where the memory 4 stores an identity correspondence relationship between the sensing element 11 and the antenna radiator 3, and the identity correspondence relationship defines a relationship whether the sensing element 11 is the antenna radiator 3, and the processor 2 determines, according to the identity correspondence relationship, that at least one sensing element 11 connected to the detection channel that has a fault or the sensing element 11 that has a fault is the antenna radiator 3, and then determines that the at least one sensing element 11 connected to the detection channel that has a fault or the sensing element 11 that has a fault is the target antenna radiator 3 affected by the fault.

The antenna radiator 3 includes a radiator of at least one of an FPC (flexible printed circuit) antenna, an LDS (Laser-Direct-structuring) antenna, a PDS (printed Direct-structuring) antenna, and a metal frame antenna.

The antenna radiator 3 may support transceiving of antenna radio frequency signals of one or more communication systems, for example, the antenna radiator 3 supports cellular and NFC, or supports WIFI and NFC, or supports GPS and NFC, so that when the antenna radiator 3 is shared as the sensing element 11, triple functions such as cellular + NFC + sensing element, or WIFI + NFC + sensing element, or GPS + NFC + sensing element may be implemented. In some embodiments, the antenna radiator 3 may also support other functions, such as wireless charging, and specifically, may be a triple function of NFC + wireless charging + inductive element.

In some embodiments, at least some of the plurality of sensing elements 11 may also be metal bodies in the electronic device of the electronic apparatus 100, that is, in some embodiments, at least some of the sensing elements 11 may also multiplex metal bodies in the electronic device that the electronic apparatus 100 originally includes. When determining that a detection channel fault occurs, the processor 2 determines at least one target sensing element 11 connected to the detection channel 121 that has the fault, determines the position of the at least one target sensing element 11, and determines, according to the position correspondence between the sensing element 11 and the antenna radiator 3, that the antenna radiator 3 corresponding to the position of the target sensing element 11 is the target antenna radiator 3. When determining that the sensing element fails, the processor 2 may also determine the position of the at least one target sensing element 11 that fails, and determine, according to the position correspondence between the sensing element and the antenna radiator, that the antenna radiator 3 corresponding to the position of the target sensing element 11 is the target antenna radiator 3. The antenna radiator 3 corresponding to the position of the target inductive element 11 is the antenna radiator 3, the distance between the antenna radiator 3 and the position of the target inductive element 11 is smaller than a preset value. The preset value may be 5mm, 8 mm, etc.

The metal body in the electronic device comprises at least one of a mechanical key, a fingerprint module, a telephone receiver, a loudspeaker module, a metal structure in a wireless charging structure, a metal decorative ring of a camera, a metal plate on a circuit board support, a metal card support and a nanocrystalline or ceramic ferrite of an NFC module.

In some embodiments, a binding relationship is formed between each sensing channel 121 and the corresponding connected sensing element 11, and the memory 4 further stores a corresponding relationship between each sensing channel 121 and the position of the corresponding connected sensing element 11. The positions of the sensing elements 11 are positions on the electronic device 100, and may be obtained in advance according to actual positions of the sensing elements 11 on the electronic device 100 and stored in the memory 4. After determining the detection channel 121 with the fault, the processor 2 determines the position of the detection channel 121 with the fault, which is correspondingly connected with the at least one target sensing element 11, according to the corresponding relationship between each detection channel and the position of the corresponding connected sensing element.

In some embodiments, the memory 4 also pre-stores the position information of each antenna radiator 3. When the processor 2 determines that the target sensing element 11 is not the antenna radiator 3 according to the identity correspondence, it may further determine that the antenna radiator 3 corresponding to the position of the target sensing element 11 is the target antenna radiator 3 according to the position correspondence between the sensing element 11 and the antenna radiator 3. As described above, the antenna radiator 3 corresponding to the position of the target inductive element 11 is the antenna radiator 3 whose distance from the position of the target inductive element 11 is smaller than the preset value, that is, the antenna radiator is close to the target inductive element 11. When the sensing elements 11 are metal bodies in the electronic device of the electronic device 100, after the processor 2 determines the position of the target sensing element 11, it may be determined that the antenna radiator 3 having the distance from the target sensing element 11 smaller than the preset value is the target antenna radiator 3 close to the target sensing element 11 according to the position information of each antenna radiator 3.

As mentioned above, each sensing element 11 is configured to generate a sensing signal when sensing that a human body approaches, the sensing controller 12 generates proximity sensing data when receiving the sensing signal generated by the sensing element 11 through the detection channel 121 at any time, and reports the proximity sensing data to the processor 2, and the processor 2 determines that a sensing element fault occurs when detecting that a reporting frequency of the proximity sensing data exceeds a preset frequency.

That is, in some embodiments, the processor 2 determines that a sensing element failure occurs by detecting that the reporting frequency of the proximity sensing data exceeds a preset frequency.

That is, in some embodiments, when some or all of the plurality of sensing elements are antenna radiators, the processor 2 may determine that a sensing element fault occurs when it is detected that the reporting frequency of the proximity sensing data exceeds a preset frequency.

Fig. 2 is a block diagram of a partial structure of the electronic device 100 when the inductive element 11 is the antenna radiator 3 according to an embodiment of the present disclosure. As shown in fig. 2, each detection channel 121 is connected at least in series with an isolation inductor L1, and the induction controller 12 is connected to the corresponding induction element 11/antenna radiator 3 through the detection channel 121 connected in series with the isolation inductor L1. The isolation inductor L1 is configured to filter a high-frequency signal, so as to avoid interference between the induction controller 12 and the antenna radiator 3 when the antenna radiator 3 receives and transmits a radio frequency signal.

In addition, in order to realize the radio frequency transceiving function of the antenna radiator 3, the antenna radiator 3 is further connected to a feed source S1 through a matching tuning circuit 31, where the feed source S1 is configured to provide a radio frequency excitation signal for the antenna radiator 3, so that the antenna radiator 3 can support transceiving of radio frequency signals of a corresponding frequency band. The matching tuning circuit 31 is used for matching tuning.

The antenna radiator 3 is connected with the matching tuning circuit 31 through a first isolation capacitor C1, and the antenna radiator 3 is grounded through a second isolation capacitor C2, so that the effect of suspension is achieved through the first isolation capacitor and the second isolation capacitor C2, and the requirement of human body proximity sensing is met.

As shown in fig. 2, a connection node N1 of the matching tuning circuit 31 and the first isolation capacitor C1 is also grounded through a shunt inductor module L2. In general, when the electronic device 100 has a plurality of antenna radiators 3, the electronic device 100 frequently determines the antenna radiator 3 with the best communication quality at present, and frequently switches the antenna radiators 3, so that the capacitance parameter of the antenna radiator 3 changes, and the sensing signal may be generated, and in order to avoid being received by the sensing controller 12 and misjudging that a human body approaches, the bypass inductance module L2 is added, so as to guide the signal generated by switching the antenna radiators 3 to the ground, and not transmit the signal to the sensing controller 12.

The bypass inductor module L2 may include an inductor, or may further include other electronic devices.

However, if the bypass inductor module L2 is abnormal, for example, when a circuit breaking abnormality occurs, a signal generated in the switching process of the antenna radiator 3 is sent to the induction controller 12, and since the signal is sent frequently, the induction controller 12 generates proximity induction data and reports the proximity induction data frequently.

Therefore, the processor 2 may determine that a fault occurs in the sensing element when it is detected that the reporting frequency of the proximity sensing data exceeds a preset frequency.

Obviously, in other embodiments, when the plurality of sensing elements are metal bodies in the electronic device of the electronic apparatus 100, the sensing element failure may be determined in other manners. For example, when the metal body is directly grounded but not grounded through the isolation capacitor, there may be a disturbance signal in the sensing element 11, the sensing controller 12 will continuously receive the disturbance signal and continuously generate the proximity sensing data, and the processor 2 may determine that a sensing element fault occurs when the duration of the proximity sensing data exceeds a preset duration.

In some embodiments, the correspondence relationship between each detection channel 121 and the position of the corresponding connected sensing element 11 stored in the memory 4 specifically includes the correspondence relationship between the identification and the position of each detection channel 121 and the corresponding connected sensing element 11. The sensing controller 12 may generate proximity sensing data corresponding to each detection channel 121 according to the correspondence relationship between the identification and the position of each detection channel and the corresponding connected sensing element 11 stored in the memory 4. The proximity sensing data of the detection channel includes the identification and position data of each sensing element 11 connected to the detection channel 121.

The processor 2 can determine the sensing element 11 generating the sensing signal and determine that the sensing element is the target sensing element 11 with the fault according to the identification and the position data of the sensing element 11 in the proximity sensing data. And when the processor 2 determines that the sensing element 11 is the antenna radiator 3 according to the identity correspondence, it may be determined that the sensing element 11 having the fault is the target antenna radiator 3 affected by the fault, and the operating power of the target antenna radiator 3 is controlled to be reduced to a target operating power.

In this application, the processor is in when the proximity sensing module breaks down, control will the operating power of target antenna radiator reduces to target operating power, refers to, maintains the operating power of target antenna radiator is target operating power always, until the trouble is relieved.

As mentioned above, when the sensing controller 12 is not faulty, i.e. normal, the normal sensing device 11 can generate a sensing signal when sensing the approach of a human body for the normal detection channel 121 and the normal sensing device. When receiving the sensing signal generated by the sensing element 11 through the normal detection channel 121, the sensing controller 12 generates proximity sensing data and reports the proximity sensing data to the processor 2. The processor 2 is connected to the sensing controller 12, and is configured to receive the proximity sensing data, determine that a human body approaches, and perform proximity sensing control.

In some embodiments, the processor 2 performing proximity sensing control may include: the processor 2 determines the sensing element 11 generating the sensing signal and the position of the sensing element 11 according to the sensing data, determines the target antenna radiator 3 corresponding to the sensing element 11 according to the preset corresponding relationship between each sensing element 11 and the antenna radiator 3, and controls to reduce the working power of the target antenna radiator.

That is, in some embodiments, the processor 2 performing proximity sensing control may include controlling to reduce the operating power of the antenna radiator 3. As mentioned above, the antenna radiator 3 corresponding to the inductive element 11 may be an inductive element located in the same area/close position of the electronic device 100 as the inductive element 11. Obviously, in other embodiments, the processor 2 may also perform proximity sensing control, including controlling to turn off the screen, controlling to adjust the current playing volume, and so on. The current playing volume can be adjusted to be lower by controlling and adjusting the current playing volume.

Specifically, when the processor 2 performs proximity sensing control to control reduction of the operating power of the antenna radiator, when a human body approaches a certain position of the electronic device 100, the sensing element 11 at the position senses the approach of the human body to generate a sensing signal, and the sensing signal is transmitted to the sensing controller 12 through the detection channel 121. The sensing controller 12 generates corresponding proximity sensing data according to the sensing signal and sends the proximity sensing data to the processor 2, the processor 2 determines a target sensing element 11 generating the sensing signal and a position of the target sensing element 11 according to the sensing data, determines a target antenna radiator 3 close to the position or located at the position corresponding to the target sensing element 11 according to a preset corresponding relationship between each sensing element 11 and the antenna radiator 3, and controls to reduce the working power of the target antenna radiator. Therefore, when a human body is close to a certain position of the electronic device 100, the working power of the antenna radiator close to or at the position can be timely reduced, the SAR (specific absorption rate) is effectively reduced, the safety requirement is met, and the radiation damage to the human body is reduced.

As mentioned above, some or all of the plurality of inductive elements 11 may multiplex the antenna radiator 3, or at least some of the plurality of inductive elements 11 may also be metal bodies in the electronics of the electronic device 100. Therefore, the plurality of sensing elements 11 may partially or completely reuse the antenna radiator 3 originally included in the electronic device 100, or also partially reuse a metal body in an electronic device originally included in the electronic device 100, and no separate antenna radiator is required to be additionally arranged, so that the cost can be effectively reduced, and the space occupied by the electronic device 100 is also avoided.

In the same manner as the above-mentioned method for determining the corresponding target antenna radiator 3 when a fault occurs, please refer to the foregoing description specifically.

In an embodiment, each detection channel 121 is connected to one sensing element 11, that is, the number of the detection channels 121 is the same as the number of the sensing elements 11, and the detection channels are connected in a one-to-one correspondence.

In some embodiments, the number of the detection channels 121 is smaller than the number of the sensing elements 11, and adjacent sensing elements 11 spaced apart by a distance smaller than a preset distance share one detection channel 121.

Therefore, in the present application, the adjacent sensing elements 11 having the spacing distance smaller than the preset distance share one detection channel 121, so that the number of the detection channels 121 can be effectively reduced, and the cost can be reduced.

Fig. 3 is a schematic view of the sensing elements 11 sharing one sensing channel 121 according to an embodiment of the present disclosure. In some embodiments, the sharing of one detection channel 121 by the adjacent sensing elements 11 spaced apart by a distance less than the preset distance may include: the adjacent sensing elements 11 spaced apart by a distance less than the predetermined distance are electrically connected to the common detection channel 121.

That is, each of the adjacent sensing elements 11 whose spacing distance is smaller than the preset distance is electrically connected to the same common detection channel 121. Each of the adjacent sensing elements 11 with the spacing distance smaller than the preset distance may be connected to the same detection channel 121 through a connection wire such as a conducting wire, an FPC (flexible printed circuit board), or a plurality of branch wires may be led out from the end of the shared detection channel 121 and respectively electrically connected to each of the adjacent sensing elements 11 with the spacing distance smaller than the preset distance.

The preset distance is a predetermined distance that allows adjacent sensing elements 11 to be electrically connected to the same detection channel 121, and may be, for example, 2mm (millimeter), 2.5mm, and so on.

In some embodiments, the detection channel 121 is a detection line connected with at least an isolation inductor in series, and is used for filtering interference of high frequency signals. In some embodiments, an RC filter circuit is further connected in series in the detection line for filtering a noise signal generated by the sensing controller 12 to avoid interference with the sensing element 11, and in particular, when the sensing element 11 is a multiplexed antenna radiator or a metal body in an electronic device of the electronic device 100, to avoid interference with normal operation of the antenna radiator or the electronic device.

The sensing controller 12 further includes a plurality of detection pins P1, and each detection channel 121 is further connected to one detection pin P1 of the sensing controller 12. The sensing channel 121 is configured to transmit a sensing signal generated by the sensing element 11 to the sensing controller 12, specifically, to a corresponding sensing pin P1 of the sensing controller 12.

Please refer to fig. 4, which is a schematic structural diagram illustrating that the sensing elements 11 share one sensing channel 121 according to an embodiment of the present application. In some embodiments, the inductive element 11 is an antenna radiator of the multiplexing electronic device, and is specifically a multiplexing metal bezel antenna radiator. As shown in fig. 4, the electronic device further includes a metal frame 5, wherein the metal frame 5 is provided with at least one gap 51 to divide the metal frame 5 into at least one frame section 52, and the frame section 52 forms the antenna radiator 3.

As shown in fig. 4, the at least one bezel segment 52 includes a first bezel segment 521 and a second bezel segment 522, and the first bezel segment 521 and the second bezel segment 522 respectively form an antenna radiator 3. The first frame segment 521 is provided with a first feeding point K1 and a first grounding point G1, the first grounding point G1 is disposed at a position closer to the second frame segment 522 than the first feeding point K1, and the first feeding point K1 is disposed at a side of the first grounding point G1 away from the second frame segment 522. The first feed point K1 is connected to a first feed source S11, and the first ground point G1 is grounded through an isolation capacitor C1.

The second frame section 522 is provided with a second feeding point K2 and a second grounding point G2, the second grounding point G2 is disposed at a position closer to the first frame section 521 than the second feeding point K2, and the second feeding point K2 is disposed at a side of the second grounding point G2 away from the first frame section 521. The second feed point K2 is connected to a second feed source S12, and the second ground point G2 is grounded through an isolation capacitor C2.

Because the first bezel segment 521 and the second bezel segment 522 are disposed close to each other, and the distance therebetween is smaller than a preset distance, the antenna radiators formed by the first bezel segment 521 and the second bezel segment 522 may share one detection channel 121. As shown in fig. 4, the same detection channel 121 can be electrically connected to both the first frame segment 521 and the second frame segment 522. Specifically, the same detection channel 121 may be connected to a portion of the first frame segment 521 on a side of the first grounding point G1 close to the second frame segment 522, and also connected to a portion of the second frame segment 522 on a side of the second grounding point G2 close to the first frame segment 521.

The antenna radiator 3 multiplexed as the inductive element 11 may also be a radiator of an FPC antenna, or the like, and when the FPC antenna includes multiple sections of antenna bodies, and a gap between two adjacent sections of antenna bodies is small, and radiation ends of the antenna radiators formed by the adjacent sections of antenna bodies are close to each other, the adjacent inductive element 11 of the common hot spot may also be formed.

Since the sensing element 11 is necessary to transmit signals through the detection channel 121 even when the sensing element 11 fails, and no matter the detection channel 121 is connected to only one sensing element 11 or shared by adjacent sensing elements 11 spaced apart by a distance less than the preset distance, the positions of the sensing element 11 and the adjacent sensing elements 11 spaced apart by a distance less than the preset distance can be regarded as positions located in substantially the same area. Therefore, the processor 2 determines the antenna radiator 3 corresponding to the failed inductive element 11, or may determine the detection channel 121 connected to the failed inductive element 11 first, and then determine that the antenna radiator 3 corresponding to at least one/all of the inductive elements 11 connected to the detection channel 121 is the target antenna radiator 3 affected by the failure.

In some embodiments, as shown in fig. 4, when the sensing element 11 needs to be grounded, the part of the sensing element 11 needing to be grounded is grounded through the isolation capacitor. So that the inductive element 11 presents a suspension effect, and meets the requirement of human body proximity induction.

For example, when one of the inductive elements 11 is the common antenna radiator 3, since the antenna radiator 3 itself needs to be grounded to form a current loop, an isolation capacitor is provided between the ground point of the antenna radiator 3 and the ground, and the ground is grounded through the isolation capacitor. Alternatively, when one of the sensing elements 11 is a metal body in the shared electronic device and the metal body in the electronic device has a grounding requirement, the metal body is also grounded through the isolation capacitor.

Therefore, when the antenna radiator 3 or the metal body of the electronic device is shared, the sensing element 11 can sense the approach of a human body to generate a sensing signal without affecting the function of the antenna radiator 3 or the electronic device, and transmit the sensing signal to the sensing controller 12.

In some embodiments, as shown in fig. 4, when one of the inductive elements 11 is a common antenna radiator 3, an isolation capacitor is also connected between the antenna radiator 3 and the corresponding feed S1.
