Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
FIG. 1 is a flow chart illustrating a method of acquiring magnetic field data in accordance with an exemplary embodiment; the method of the embodiment may be applied to a control component (e.g., a smartphone, a tablet computer, a laptop computer, or a wearable device, etc.) of a magnetic detection sensor.
As shown in fig. 1, the method comprises the following steps S101-S102:
in step S101, in the process of acquiring raw magnetic field data by the magnetic detection sensor, operation information of a radio frequency module executing a target operation is acquired.
In this embodiment, a control component (hereinafter, referred to as a control component) of the magnetic detection sensor may acquire operation information of the radio frequency module executing the target operation in a process of acquiring the original magnetic field data by the magnetic detection sensor.
In an embodiment, the radio frequency module may include an NFC (Near Field Communication) module, a Wi-Fi (WIreless-Fidelity) module, and other modules that perform operations such as Communication based on radio frequency identification technology or pulse scanning network. Accordingly, the target operation performed by the rf module includes communication or pulse scanning network, which is not limited in this embodiment.
The control component of the magnetic detection Sensor may be a control Core component (i.e., a Sensor Core) of the magnetic detection Sensor, or the like.
For example, the control unit may obtain operation information of the rf module performing the target operation, such as an operation time and an operation frequency of the rf module performing the target operation, in a process of the controlled magnetic detection sensor acquiring the raw magnetic field data, which is not limited in this embodiment.
In an embodiment, the control component may obtain the operation information of the radio frequency module executing the target operation based on any one of the following manners (1) to (6), and the obtained result is applicable to the subsequent steps of this embodiment:
(1) and receiving first operation information of the target operation executed by the radio frequency module sent by the system control component.
The first operation information comprises information which is acquired by a control component of the radio frequency module and sent to a system control component.
For example, when the radio frequency module executes the target operation, the control component (e.g., modem core, etc.) of the corresponding radio frequency module may be notified of operation information of the radio frequency module itself executing the target operation, and then the control component of the radio frequency module may send the operation information to the system control component (e.g., control core in the application processor AP), and then the control component may receive the operation information (i.e., first operation information) of the radio frequency module executing the target operation, which is sent by the system control component.
(2) And receiving second operation information of the target operation executed by the radio frequency module, which is sent by the control component of the radio frequency module.
Wherein the second operation information includes information that the radio frequency module transmits to a control part of the radio frequency module.
For example, when the rf module performs the target operation, the control component of the rf module may communicate with the control component of the sensor to notify the control component of the sensor of the second operation information (e.g., when to transmit a signal, etc.) of the rf module, and the control component of the sensor may receive the operation information (i.e., the second operation information) of the rf module performing the target operation.
(3) And receiving third operation information which is sent by the radio frequency module and used for executing the target operation.
For example, the rf module may communicate with the sensor based on additional control circuitry within the sensor. When the radio frequency module performs the target operation, operation information (i.e., third operation information) of the radio frequency module performing the target operation may be directly transmitted to the sensor based on the control circuit described above.
(4) And acquiring fourth operation information of the radio frequency module for executing the target operation from the control part of the radio frequency module based on the pre-registered monitoring program.
For example, the control part of the sensor may listen to the control part of the radio frequency module based on a previously registered listener, thereby acquiring operation information (i.e., fourth operation information) that the radio frequency module performs a target operation.
(5) And detecting fifth operation information of the radio frequency module executing the target operation based on the pre-constructed signal connection.
For example, when the control unit of the sensor can be in signal connection with the rf module, and further, the operation information (i.e., the fifth operation information) of the rf module performing the target operation can be detected based on the connection
(6) And detecting sixth operation information of the radio frequency module executing the target operation through the application processor AP.
For example, the application processor AP may detect operation information (i.e., sixth operation information) of the radio frequency module performing the target operation, and the control part of the sensor may acquire the sixth operation information from the application processor AP based on a preset signal connection.
In step S102, in response to the acquisition of the operation information, non-interference magnetic field data is acquired based on the operation information and the magnetism detection sensor.
In this embodiment, after the operation information of the radio frequency module executing the target operation is obtained in the process of acquiring the original magnetic field data by the magnetism detection sensor, if the operation information is obtained, the non-interference magnetic field data may be obtained based on the operation information and the magnetism detection sensor.
For example, after operation information of the radio frequency module executing the target operation is acquired, the time for the magnetic detection sensor to acquire the magnetic field data may be controlled based on the operation information; or, removing the data of received interference from the raw magnetic field data collected by the magnetism detection sensor based on the operation information, thereby obtaining the data of the interference-free magnetic field.
In another embodiment, the above-mentioned manner of acquiring the interference-free magnetic field data based on the operation information and the magnetic detection sensor can also be referred to the following embodiment shown in fig. 2, which will not be described in detail herein.
As can be seen from the above description, in the method of this embodiment, by acquiring the operation information of the radio frequency module executing the target operation in the process of acquiring the original magnetic field data by the magnetic detection sensor, and acquiring the non-interference magnetic field data based on the operation information and the magnetic detection sensor in response to the acquisition of the operation information, the magnetic interference of the radio frequency module on the magnetic detection sensor can be suppressed, and the accuracy of acquiring the magnetic field data by the magnetic detection sensor can be improved.
FIG. 2 is a flow diagram illustrating how unperturbed magnetic field data is acquired based on the operational information and the magnetic detection sensor, according to an exemplary embodiment; the present embodiment is exemplified by how to acquire non-interfering magnetic field data based on the operation information and the magnetism detection sensor on the basis of the above-described embodiments. As shown in fig. 2, the step S102 of acquiring non-interfering magnetic field data based on the operation information and the magnetism detection sensor in response to the acquisition of the operation information may include the following steps S201 to S202:
in step S201, the disturbing magnetic field data caused by the target operation is determined based on the operation information.
In this embodiment, after operation information of a radio frequency module executing a target operation is acquired in a process of acquiring original magnetic field data by the magnetic detection sensor, interference magnetic field data caused by the target operation may be determined based on the operation information.
The interference magnetic field data caused by the target operation may include magnetic field data collected by the magnetic detection sensor when the radio frequency module performs the target operation. It is understood that, since the rf module performs the target operation, for example, when performing a pulsed scanning network, a pulsed power supply change is caused, and thus an interference magnetic field is generated. In this case, the magnetic field data collected by the magnetic detection sensor is affected by the disturbing magnetic field. That is, the magnetic field data collected by the magnetism detection sensor includes the disturbance magnetic field data caused by the disturbance magnetic field. After obtaining the operation information of the rf module performing the target operation, such as the operation time, the corresponding disturbing magnetic field data can be determined based on the operation information, so as to remove the data based on the subsequent step S202.
In another embodiment, the above-mentioned manner of determining the disturbing magnetic field data caused by the target operation based on the operation information can also be referred to the following embodiments shown in fig. 3 or fig. 4, which will not be described in detail herein.
In step S202, the interference-free magnetic field data is obtained by removing the interference-free magnetic field data from the raw magnetic field data collected based on the magnetism detection sensor.
In this embodiment, after determining the interference magnetic field data caused by the target operation based on the operation information, the interference magnetic field data may be removed from the original magnetic field data collected based on the magnetism detection sensor, so as to obtain the interference-free magnetic field data.
As can be seen from the above description, in this embodiment, the interference magnetic field data caused by the target operation is determined based on the operation information, so that the interference magnetic field data caused by the target operation executed by the radio frequency module can be accurately determined, and further, the interference magnetic field data can be subsequently removed from the original magnetic field data acquired based on the magnetism detection sensor, so as to obtain the interference magnetic field data, so that the magnetism interference of the radio frequency module on the magnetism detection sensor can be suppressed, and the accuracy of the magnetism detection sensor in acquiring the magnetic field data can be improved.
FIG. 3 is a flow chart illustrating how unperturbed magnetic field data is acquired based on the operational information and the magnetic detection sensor, according to yet another exemplary embodiment; the present embodiment is exemplified by how to acquire non-interfering magnetic field data based on the operation information and the magnetism detection sensor on the basis of the above-described embodiments.
In this embodiment, the operation information may include an operation time period.
As shown in fig. 3, the step S102 of acquiring non-interfering magnetic field data based on the operation information and the magnetism detection sensor in response to the acquisition of the operation information may include the following steps S301 to S302:
in step S301, disturbance magnetic field data caused by the target operation is determined based on target magnetic field data generated during the operation period.
In this embodiment, after the operation time period in which the radio frequency module executes the target operation is obtained in the process of acquiring the original magnetic field data by the magnetic detection sensor, the target magnetic field data generated in the operation time period may be determined as the interference magnetic field data caused by the execution of the target operation by the radio frequency module.
It is understood that, since the rf module performs the target operation, for example, when performing a pulsed scanning network, a pulsed power supply change is caused, and thus an interference magnetic field is generated. In this case, the magnetic field data collected by the magnetic detection sensor is affected by the disturbing magnetic field. Thus, by acquiring the operation time period in which the radio frequency module performs the target operation, the target magnetic field data generated in the operation time period can be determined as the interference magnetic field data caused by the target operation, so that the data can be removed based on the subsequent step S302.
In step S302, the interference magnetic field data is removed from the raw magnetic field data collected based on the magnetism detection sensor, and the interference magnetic field data is obtained.
For the explanation and explanation of step S302, reference may be made to the above embodiments, which are not described herein again.
As can be seen from the above description, in this embodiment, after the operation time period in which the radio frequency module executes the target operation is obtained, the interference magnetic field data caused by the target operation is determined based on the target magnetic field data generated in the operation time period, so that the interference magnetic field data caused by the target operation executed by the radio frequency module can be accurately determined, and then the interference magnetic field data can be removed from the original magnetic field data acquired based on the magnetism detection sensor, so that the interference magnetic field data can be obtained, the magnetism interference of the radio frequency module on the magnetism detection sensor can be suppressed, and the accuracy in which the magnetism detection sensor acquires the magnetic field data can be improved.
FIG. 4 is a flow chart illustrating how unperturbed magnetic field data is acquired based on the operational information and the magnetic detection sensor, according to another exemplary embodiment; the present embodiment is exemplified by how to acquire non-interfering magnetic field data based on the operation information and the magnetism detection sensor on the basis of the above-described embodiments.
In this embodiment, the operation information may include an operation time period and an operation frequency.
As shown in fig. 4, the step S102 of acquiring non-interfering magnetic field data based on the operation information and the magnetism detection sensor in response to the acquisition of the operation information may include the following steps S401 to S402:
in step S301, the disturbance magnetic field data caused by the target operation is determined based on the target magnetic field data generated during the operation period and having a frequency matching the operation frequency.
In this embodiment, after the operation time period and the operation frequency of the target operation executed by the radio frequency module are acquired in the process of acquiring the original magnetic field data by the magnetism detection sensor, the interference magnetic field data caused by the target operation may be determined based on the target magnetic field data which is generated in the operation time period and whose frequency matches the operation frequency.
It is understood that, since the rf module performs the target operation, for example, when performing a pulsed scanning network, a pulsed power supply change is caused, and thus an interference magnetic field is generated. In this case, the magnetic field data acquired by the magnetism detection sensor is affected by the disturbance magnetic field, that is, data due to the disturbance magnetic field is acquired in addition to the normal magnetic field data. Therefore, by acquiring the operation time period and the operation frequency of the radio frequency module for executing the target operation, the target magnetic field data which is generated in the operation time period and has the frequency matched with the operation frequency can be determined as the interference magnetic field data caused by the target operation, and the accuracy of determining the interference magnetic field data can be further improved. On this basis, the data may be removed based on the subsequent step S402.
In step S402, the interference magnetic field data is removed from the raw magnetic field data collected based on the magnetism detection sensor, and the interference magnetic field data is obtained.
For the explanation and explanation of step S402, reference may be made to the above embodiments, which are not described herein again.
As can be seen from the above description, in this embodiment, after the operation time period and the operation frequency of the target operation executed by the radio frequency module are obtained, the interference magnetic field data caused by the target operation is determined based on the target magnetic field data which is generated in the operation time period and has a frequency matched with the operation frequency, so that the interference magnetic field data caused by the target operation executed by the radio frequency module can be accurately determined, and further the interference magnetic field data can be removed from the original magnetic field data acquired by the magnetism detection sensor, so as to obtain the interference-free magnetic field data, so that the magnetism interference of the radio frequency module on the magnetism detection sensor can be more accurately suppressed, and the accuracy of the magnetism detection sensor in acquiring the magnetic field data can be further improved.

For the explanation and explanation of step S501, reference may be made to the above embodiments, which are not described herein again.
In step S502, the magnetism detection sensor is controlled to stop collecting magnetic field data in the operation time period, and non-interference magnetic field data collected by the magnetism detection sensor at a time other than the operation time period is obtained.
In this embodiment, after the operation information of the target operation executed by the radio frequency module is obtained, for example, after the operation time period, the magnetic detection sensor may be controlled to stop collecting the magnetic field data in the operation time period, so that the magnetic field data collected by the magnetic detection sensor at a time other than the operation time period, that is, the magnetic field data without interference may be obtained, and thus, the magnetic interference of the radio frequency module on the magnetic detection sensor may be suppressed.
As can be seen from the above description, in the process of acquiring the original magnetic field data by the magnetism detection sensor, the present embodiment obtains the operation time period in which the radio frequency module executes the target operation, and then controls the magnetism detection sensor to stop acquiring the magnetic field data in the operation time period, so that the non-interference magnetic field data acquired by the magnetism detection sensor at the time outside the operation time period can be obtained, the magnetism interference of the radio frequency module on the magnetism detection sensor can be suppressed, the accuracy of acquiring the magnetic field data by the magnetism detection sensor is improved, and the subsequent application effect on the non-interference magnetic field data acquired by the magnetism detection sensor can be improved.
