Likewise, the following examples are only some examples but not all examples of the present application, and all other examples obtained by those of ordinary skill in the art without any inventive work are intended to be within the scope of the present application.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

It should be noted that the terms "first", "second" and "third" in the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of indicated technical features. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless explicitly specifically limited otherwise.

Referring to fig. 1, fig. 1 is a schematic perspective view of an electronic device according to an embodiment of the present disclosure. The present application provides an electronic device 1000. Specifically, the electronic device 1000 may be any of various types of computer system devices (only one modality shown in fig. 1 by way of example) that are mobile or portable and that perform wireless communications. Specifically, the electronic device 1000 may be a mobile phone or smart phone (e.g., an iPhone (TM) based, Android (TM) based phone), a Portable gaming device (e.g., a Nintendo DS (TM), a PlayStation Portable (TM), a Game Advance (TM), an iPhone (TM)), a laptop, a PDA, a Portable Internet device, a music player and data storage device, other handheld devices and devices such as a headset, and the like, and the electronic device 1000 may also be other wearable devices that require charging (e.g., a Head Mounted Device (HMD) such as an electronic bracelet, an electronic necklace, an electronic device or a smart watch).

The electronic device 1000 may also be any of a number of electronic devices including, but not limited to, cellular phones, smart phones, other wireless communication devices, personal digital assistants, audio players, other media players, music recorders, video recorders, other media recorders, radios, medical devices, vehicle transportation equipment, calculators, programmable remote controllers, pagers, laptop computers, desktop computers, printers, netbook computers, Personal Digital Assistants (PDAs), Portable Multimedia Players (PMPs), moving Picture experts group (MPEG-1 or MPEG-2) Audio layer 3(MP3) players, portable medical devices, and digital cameras and combinations thereof.

In some cases, the electronic device 1000 may perform multiple functions (e.g., playing music, displaying videos, storing pictures, and receiving and sending telephone calls). If desired, the electronic device 1000 may be a device such as a cellular telephone, media player, other handheld device, wrist watch device, pendant device, earpiece device, or other compact portable device.

In the related art, most electronic devices such as mobile phones have an NFC function, and NFC tags of terminals are also available in the market, so that the NFC mobile phones can realize personalized application customization based on the NFC readable NFC tags. For example, the a-tag may be defined as a silent mode NFC tag, and when the NFC of the mobile phone scans the a-tag, the mobile phone enters the silent mode, even if the NFC of the mobile phone is away from the a-tag, the mobile phone is still in the silent mode, and the silent mode is not affected by the NFC of the mobile phone being away from the short-time response NFC tag.

For example, the NFC of the mobile phone is moved after reading the corresponding NFC tag, and the NFC of the mobile phone is restored to a normal functional state after the mobile phone is moved, i.e., the NFC of the mobile phone is temporarily contacted with the entrance guard tag and public transportation, and corresponding response work such as opening a door, payment, and the like can be completed.

For example, the mobile phone holder is provided with a vehicle-mounted mode tag, and the user puts the mobile phone on the mobile phone holder and the mobile phone enters a vehicle-mounted mode. However, if the mobile phone is far from the mobile phone holder, the in-vehicle mode of the mobile phone disappears. In other words, the NFC of the mobile phone needs to continuously read the in-vehicle mode tag to make the mobile phone in the in-vehicle mode.

As can be appreciated, for the car mode tag, the NFC needs to continuously read the car mode tag so that the mobile phone maintains the car mode. However, the mobile phone continuously reads the vehicle mode tag, so that the mobile phone consumes more power and generates heat seriously.

In the related art, the electronic device NFC continuously and periodically reads the content of the NFC tag, and not only periodically sends a class a card inquiry command (such as reqa (Request a command) or WUPA (Wake-UP a command)), but also receives a class a card inquiry response (such as ATQA (Answer To Request, Type a)), but also periodically performs data interaction, especially I-Block data interaction. In the related art, the period for sending the card inquiry command and receiving the card inquiry response is usually 4ms, and correspondingly, the interaction period of the I-Block data is also 4 ms. It will be appreciated that the shorter the command transmission period, the more sensitive the handset will respond, but the greater the corresponding power consumption. In view of this, it is actually necessary to provide a new method for reducing NFC power consumption.

Referring to fig. 2, fig. 2 is a flowchart of a method for reducing NFC power consumption according to an embodiment of the present application. The embodiment of the application provides a method for reducing the power consumption of NFC, which is applied to an electronic device 1000 and used for scanning an NFC tag. The method for reducing the NFC power consumption comprises the following steps:

step S01, the NFC tag is scanned.

Specifically, the electronic device 1000 is close to the NFC tag, so that the electronic device NFC corresponds to the NFC tag, so that the electronic device NFC can scan the NFC tag and identify the NFC tag. Specifically, information such as the encoding, the mode type, and the like of the NFC tag is identified.

Referring to fig. 3 and 4, fig. 3 is a sub-flowchart of an embodiment of step S02 in the flowchart shown in fig. 2, and fig. 4 is a sub-flowchart of another embodiment of step S02 in the flowchart shown in fig. 2. And step S02, judging whether the NFC label is a preset type label.

The preset type tags can be roughly divided into two types, one type is a type of pre-stored special mode tags, the electronic device NFC needs to continuously read the pre-stored special mode tags so that the mobile phone can keep a corresponding special working mode, and once the mobile phone is far away from the pre-stored special mode tags, the mobile phone is immediately separated from the special working mode (such as the vehicle-mounted mode tags mentioned above); the other type is a non-prestored special mode tag, specifically, the electronic device NFC is placed together with a device carrying a chip, such as a bank card, an access card, and the like, of the non-prestored special mode tag, and the electronic device NFC periodically and uninterruptedly scans the non-prestored special mode tag. It can be understood that as the electronic device is continuously updated, more and more new special tags are designed to cope with new and different application scenarios, but the pre-stored special mode tags of the electronic device are limited, and if the preset type tags of the electronic device cannot be updated, it is difficult to meet the increasing new requirements of the user.

Referring to fig. 3, in one embodiment, the predetermined type tag is a pre-stored special mode tag. Step S02 may include the following sub-steps:

step S21, compare the NFC tag with the preset type tag.

Specifically, the preset type tag in this embodiment is one of pre-stored special mode tags stored in a database of the electronic device 1000. Specifically, the factory setting of the electronic device 1000 may be pre-stored with information such as a part of codes and mode types of the pre-stored special mode tags, and a user may also set the information of the part of codes and mode types of the pre-stored special mode tags according to a requirement, so as to complement and perfect database information of the electronic device 1000.

The information of the NFC tag is compared with pre-stored special mode tag information stored in a database of the electronic device 1000. Specifically, the code or the mode type of the NFC tag is queried in the database, and any information of the code or the mode type of the NFC tag can be queried in the database, so that the NFC tag is one of the preset type tags, that is, the NFC tag is a preset type tag that prestores a special mode tag, otherwise, the NFC tag is not a preset type tag that prestores a special mode tag.

In step S22a, if the NFC tag is one of the preset type tags, the NFC tag is a preset type tag.

Referring to fig. 4, in another embodiment, the predetermined type tag is a non-pre-stored special mode tag.

On the basis of the step S21 in the above embodiment, the step S02 may further include the following steps:

step S22b, if the NFC tag is not one of the preset types of tags, determine whether the electronic device NFC scans the NFC tag according to a default mode.

The NFC label is not one of the preset type labels, namely the NFC label is not the preset type label of the pre-stored special mode label, and whether the NFC label is scanned according to a default mode or not is judged.

The default mode, that is, the NFC conventional mode of the electronic device, specifically refers to a mode in which the electronic device NFC periodically and uninterruptedly scans the NFC tag, where a period T of the default mode is usually 4ms, and the electronic device NFC always performs data exchange with the NFC tag once in each period. Specifically, when the electronic device NFC is placed together with the non-prestored special mode tag, the electronic device NFC periodically and uninterruptedly scans the non-prestored special mode tag until the non-prestored special mode tag is out of the working range of the electronic device NFC.

Step S23b, if the NFC tag is scanned by the electronic device NFC according to the default mode, the NFC tag is defined as a preset type tag that is not a pre-stored special mode tag.

It is understood that the preset type tag of the non-pre-stored special mode tag does not exist in the database of the preset type tag of the electronic device. The NFC tag, such as a bank card, enters the working range of the NFC of the electronic device, and the NFC of the electronic device scans the NFC tag according to a default mode until the NFC tag is separated from the NFC tag. It will be understood that it is not necessary for the electronic device NFC to scan it in the default mode, and that with a high probability the user will bring the bank card together with the electronic device, but keeping the electronic device NFC in the continuous operating state causes a lot of power consumption. The high-power consumption of the electronic equipment NFC and other chip carrying devices commonly used in life, such as bank cards, access controls and the like, caused by error contact can be greatly reduced by defining the electronic equipment NFC as a preset type label of a non-prestored special mode label.

Or the NFC tag may also be a special mode tag that is newly made available or a special mode tag that is not recorded for other reasons, and since the special mode tag is not recorded in the database of the electronic device, the NFC of the electronic device performs periodic scanning according to a default mode, so that power consumption is relatively large. The non-prestoring special mode label can be supplemented to the prestoring special mode label according to the user demand, so that the NFC label can be rapidly identified by the electronic equipment NFC conveniently, and the power consumption of the electronic equipment is reduced. Through the mode, the preset type label database of the electronic equipment can be enriched, so that the NFC of the electronic equipment can quickly identify the new special mode label.

Referring to fig. 5 to 8, fig. 5 is a sub-flowchart of an embodiment of step S03 shown in fig. 2, fig. 6 is a sub-flowchart of step S32 shown in fig. 5, fig. 7 is a sub-flowchart of another embodiment of step S03 in the flowchart shown in fig. 2, and fig. 8 is a sub-flowchart of step S33 shown in fig. 5. And step S03, if the NFC label is a preset type label, scanning the NFC label according to a preset mode to monitor whether the NFC label is separated from the NFC working range of the electronic equipment.

Specifically, the scanning the NFC tag according to the preset mode in step S03 may include the following steps:

and step S31, reading the data information in the NFC label.

In the embodiment of the application, considering that the NFC tag is a preset type tag, information (I-Block data) of data interaction at each time is the same, so that the data information of the NFC tag is read by the electronic device NFC, the number of times of data information of the NFC tag is reduced, and the power consumption of the electronic device 1000 can be effectively reduced.

Step S32, scanning the NFC tag according to the first time interval in the first preset time period, and monitoring whether the NFC tag is separated from the NFC operating range of the electronic device in the first preset time period.

The first preset time period refers to a time period (e.g., 5min) from when the NFC tag is determined as the preset type tag to after the NFC tag is delayed, and a duration of the first preset time period may be set by a default (i.e., factory setting) of the system, or may be set autonomously according to a user requirement, which is not limited specifically herein.

The first time interval T1 may be greater than the period T of the default mode, so as to reduce the scanning period of the NFC device, thereby achieving the purpose of reducing power consumption. In this embodiment, the first time interval t1 may be 1s or 2s, and is not limited herein.

Referring to fig. 6, step S32 includes the following steps:

step S321, a card inquiry command is issued to the NFC tag according to the first time interval.

Specifically, each time a polling card command, such as REQA or WUPA, is sent at a cycle of a first time interval to find out whether the NFC tag is out of the NFC operating range of the electronic device.

In step S322, if the card inquiry response of the NFC tag is received, the NFC tag does not depart from the NFC working range of the electronic device within the first preset time period.

Specifically, each first time interval, when the electronic device 1000 always receives the card inquiry response of the NFC tag, such as ATQA, it may be determined that the NFC tag does not leave the NFC operating range of the electronic device within the first preset time period, that is, the electronic device 1000 is never removed from the NFC tag. If the electronic device 1000 does not receive a card inquiry response, such as ATQA, within any first time interval, it is determined that the handset is exiting the default mode. If it is determined that the electronic device 1000 is not removed from the NFC tag, step 33 is entered:

referring to fig. 7 and 8, in step S33, if the NFC tag is not separated from the NFC operating range of the electronic device within the first preset time period, the NFC tag is scanned within the second preset time period at a second time interval.

The second time interval t2 is greater than the first time interval t1, so as to further reduce the scanning period of the NFC electronic device, and further achieve the purpose of reducing power consumption. In this embodiment, the duration t2 of the second time interval may be 3s, 5s, and is not limited herein.

The second preset time period refers to a period of time from the end of the first preset time period to the delay, and the duration of the second preset time period may be set by default (i.e., factory setting) by the system, or may be set autonomously according to the user requirement, which is not limited specifically herein.

Wherein, step S33 includes the following steps:

and step 331, sending a card inquiry command to the NFC tag according to a second time interval.

Specifically, each time a polling card command, such as REQA or WUPA, is sent at a period of a second time interval to find out whether the NFC tag is out of the NFC operating range of the electronic device.

In step S332, if the card inquiry response of the NFC tag is received, the NFC tag does not depart from the NFC working range of the electronic device within the second preset time period.

Specifically, the electronic device 1000 always receives the card inquiry response of the NFC tag, such as ATQA, in each second time interval, and it can be determined that the NFC tag does not leave the NFC operating range of the electronic device within the second preset time period, that is, the electronic device 1000 is never removed from the NFC tag. If the electronic device 1000 does not receive a card inquiry response, such as ATQA, within any second time interval, it is determined that the handset is exiting the default mode.

According to the method for reducing the NFC power consumption, whether the NFC label is the preset type label or not is judged, and if the NFC label is the preset type label, the NFC label is scanned according to the preset mode so as to monitor whether the NFC label is separated from the NFC working range of the electronic equipment or not. By the mode, the problem of power consumption of the electronic device 1000 placed on a specific tag (namely a preset type tag) for a long time can be solved, and meanwhile, the normal reading function of the electronic device NFC in other scenes is not influenced.

Referring to fig. 9, an embodiment of the present application further provides a system 100 for reducing power consumption, which is applied in an electronic device 1000 and used for scanning an NFC tag. The system 100 may include a scanning module 10, a determination module 20, and a processor module 30. The scanning module 10 is used for scanning an NFC tag, the judging module 20 is electrically connected to the scanning module 10 and is used for judging whether the NFC tag is a preset type tag, the processor module 30 is electrically connected to the judging module 20 and receives a judgment result of the judging module 20, and if the judging module judges that the NFC tag is the preset type tag, the processor module 30 controls the scanning module 10 to scan the NFC tag according to a preset mode so as to monitor whether the NFC tag is separated from the working range of the scanning module 10. If the NFC label is separated from the working range of the scanning module 10, the NFC label exits the preset mode; if the NFC tag does not depart from the working range of the scanning module 10, the NFC tag continues to be scanned according to the preset mode.

The scanning module 10 is close to the NFC tag such that the scanning module 10 corresponds to the NFC tag to enable the scanning module 10 to scan the NFC tag.

The judging module 20 may include a storage unit 21 and a judging unit 22. The storage unit 21 may store a plurality of preset type tags. Specifically, the storage unit 21 may be pre-stored with information such as a code and a mode type of a part of the pre-stored special mode tag, and a user may set the information of the code and the mode type of the part of the pre-stored special mode tag by himself or herself to complement and perfect the database information of the electronic device 1000.

In an embodiment, the determining unit 22 is configured to compare the NFC tag with preset type tags, and if the NFC tag is one of the preset type tags, the NFC tag is the preset type tag. Specifically, the determining unit 22 is configured to compare the information of the NFC tag with pre-stored special mode tag information stored in a database of the electronic device 1000. Specifically, the code or the mode type of the NFC tag is queried in the database, and any information in the code or the mode type of the NFC tag can be queried in the database, so that the NFC tag is one of the preset type tags, that is, the NFC tag is a preset type tag in which a special mode tag is prestored, otherwise, the NFC tag is not a preset type tag in which a special mode tag is prestored.

In another embodiment, the code or the mode type of the NFC tag is queried in the database, and if any information in the code or the mode type of the NFC tag cannot be queried in the database, the NFC tag is not one of the preset type tags of the pre-stored special mode tag, and the determining unit 22 continues to determine whether the scanning module 10 scans the NFC tag according to the default mode. If the scanning module 10 scans the NFC tag according to the default mode, it is determined that the NFC tag is a preset type tag that is not a pre-stored special mode tag.

The processor module 30 may comprise a reading unit 31, a timer unit 32, a transmitting unit 33 and a receiving unit 34. The reading unit 31 is configured to read data of the pre-NFC tag, and the timer unit 32 is configured to set a time interval of the preset mode and a duration of the preset time period. The transmitting unit 33 is configured to send a card inquiry command to the NFC tag, and the receiving unit 34 is configured to receive a card inquiry response of the NFC tag. When the receiving unit 34 receives the NFC tag's card response, then the NFC tag does not leave the operating range of the scanning module 10. The processor module 30 can also set the non-pre-stored special mode label or the non-pre-stored special mode label as a pre-stored type label of the pre-stored special mode label, so that the NFC label can be rapidly identified by the electronic equipment NFC conveniently, and the power consumption of the electronic equipment is reduced.

Specifically, the reading unit 31 reads data information in the NFC tag. In the embodiment of the application, considering that the NFC tag is a preset type tag, information (I-Block data) of data interaction at each time is the same, and therefore the scanning module 10 can read the data information of the NFC tag once, so as to reduce the number of times of data information of the NFC tag, and further effectively reduce the power consumption of the electronic device 1000.

The timer unit 32 is used for setting the duration of the first preset time period, the duration of the second preset time period, and the first time interval t1 and the second time interval t 2. The first preset time period refers to a time period (for example, 5min) from the time when the NFC tag is determined as the preset type tag to the time when the NFC tag is delayed, and a duration of the first preset time period may be set by a system default (that is, factory setting), or may be set autonomously according to a user requirement, which is not particularly limited herein. The second preset time period refers to a period of time from the end of the first preset time period to the delay, and the duration of the second preset time period may be default by the system (i.e. factory setting). The second time interval is greater than the first time interval, specifically, the first time interval t1 may be 1s, 2s, and the duration t2 of the second time interval may be 3s, 5s, which is not limited herein.

The transmitting unit 33 is configured to send a card polling instruction to the NFC tag, and the receiving unit 34 is configured to receive a card polling response of the NFC tag, where if the card polling response of the NFC tag is received, the NFC tag does not leave the working range of the scanning module 10 within a first preset time period.

Specifically, the transmitting unit 33 may issue a card inquiry command such as REQA or WUPA to the NFC tag at a first time interval to find out whether the NFC tag is out of the operating range of the scanning module 10. If the receiving unit 34 receives a card inquiry response of the NFC tag, the NFC tag does not depart from the working range of the scanning module 10 within the first preset time period.

Specifically, each first time interval, when the electronic device 1000 always receives the NFC tag response to the card inquiry, such as ATQA, it can be determined that the NFC tag has not been out of the operating range of the scanning module 10 for the first predetermined period of time, i.e., the electronic device 1000 has not been removed from the NFC tag. If the electronic device 1000 does not receive a card inquiry response, such as ATQA, within any first time interval, it is determined that the handset is exiting the default mode.

The system for reducing the power consumption of the NFC tag, provided by the embodiment of the application, judges whether the NFC tag is a preset type tag through the judgment module 20, and if the NFC tag is the preset type tag, the processor module 30 controls the scanning module 10 to scan the NFC tag according to a preset mode so as to monitor whether the NFC tag is separated from the working range of the scanning module 10. By the above manner, the problem of power consumption when the electronic device 1000 is placed on a specific tag (i.e. a preset type tag) for a long time can be solved, and the normal reading function of the scanning module 10 in other scenes is not affected.
