Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant application and are not limiting of the application. It should be noted that, for the convenience of description, only the parts related to the related applications are shown in the drawings.
NFC is also called near field communication, and is a communication method increasingly used in terminal devices. NFC is a short-range, high-frequency wireless communication technology that allows contactless point-to-point data transmission and exchange of data between electronic devices.
In particular, NFC can exchange data through both active and passive modes. Fig. 1 is a schematic diagram of a passive mode of NFC communication, and as shown in fig. 1, in the passive mode, a device that starts near field communication, also called an initiating device or a master device, the master device may provide a radio frequency field during the whole communication process, and may select any one of transmission speeds of 106kbps, 212kbps, or 424kbps to transmit data to a slave device that does not need to generate the radio frequency field, and the slave device uses a load modulation technique to transmit data back to the master device at the same speed. In the active mode, the initiator and the target need to generate rf fields simultaneously for communication.
NFC is a near field communication technology developed based on RFID technology, and like RFID, NFC information is also transmitted by way of electromagnetic induction coupling in a radio frequency portion of a frequency spectrum, but there is still a great difference between the two. The transmission range of the near field communication is smaller than that of the RFID, the transmission range of the RFID can reach 0-1 m, and the near field communication has the characteristics of low cost, high bandwidth, low energy consumption and the like compared with the RFID due to the adoption of a unique signal attenuation technology.
The NFC antenna in the terminal is a coil structure at a fixed certain position, and forms a corresponding NFC coil, and when the terminal communicates with other equipment through an NFC function, the terminal needs to overlap the corresponding NFC coil with the NFC coil corresponding to other equipment in position, so that near field wireless communication can be carried out. That is to say, when the terminal communicates through NFC, the NFC coil of the terminal needs to be overlapped with the NFC coil of other devices, if the positions between the two NFC coils are not overlapped, that is, if the alignment between two NFC devices that need to communicate is not good, the communication effect will be affected, or even the defect that communication cannot be performed is caused, thereby reducing the communication efficiency. Further, due to structural limitation of the terminal, the effective NFC region cannot be enlarged by enlarging the area of the NFC antenna of the terminal, and therefore the defect that communication cannot be performed due to misalignment of NFC coils cannot be effectively overcome.
Fig. 2 is a first diagram of NFC communication, fig. 3 is a second diagram of NFC communication, and as shown in fig. 2 and fig. 3, both the terminal and the device have an NFC function, both the terminal and the device are configured with an NFC antenna having a coil structure, the terminal has an NFC region P corresponding to the NFC coil, and the device has an NFC region Q corresponding to the NFC coil. When the terminal and the device are in communication, if the NFC region P and the NFC region Q are aligned and overlapped, the terminal and the device can transmit data, however, once the NFC region P and the NFC region Q are not aligned and overlapped, the communication effect between the terminal and the device is affected, and even the terminal and the device cannot communicate with each other.
The near field communication method is applied to the terminal, the terminal can freely move the NFC coil through the connecting rod structure, and the effective area of the NFC coil is greatly expanded. In the embodiment of the application, when the terminal performs near field communication with a communication object, the terminal may identify the distribution of a magnetic field generated by the communication object on the terminal by using an internal integrated sensing device, further determine an optimal communication area, and then move the NFC coil by driving the link structure to move the NFC coil to a position where the magnetic field is strongest, that is, to a target area representing the optimal communication area, so that near field communication may be implemented in the target area, and at this time, near field communication between the terminal and the communication object may be maintained in an optimal state. Therefore, the connecting rod device configured at the terminal can drive the NFC coil to move, so that the terminal can be aligned with the NFC coil of a communication object through free movement of the NFC coil, and the defect that communication cannot be performed due to position misalignment between the NFC coil of the terminal and the NFC coil of the communication object can be overcome, so that the communication efficiency is improved, and the intelligence of the terminal is improved.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
An embodiment of the present application provides a near field communication method, which is applied to a terminal, where the terminal may include an NFC coil disposed on a link structure, and the link structure is configured to drive the NFC coil to move. Fig. 4 is a schematic implementation flow diagram of a near field communication method provided in an embodiment of the present application, and as shown in fig. 4, in the embodiment of the present application, a method for implementing vibration by a terminal may include the following steps:
step 101, detecting real-time magnetic field data; wherein the real-time magnetic field data is used for identifying the communication object.
In the embodiment of the application, the terminal can detect and obtain the real-time magnetic field data. The real-time magnetic field data may be real-time data detected by the terminal and used for representing a distribution condition of a magnetic field outside the terminal, and specifically, the real-time magnetic field data may be used for identifying a communication object.
It should be noted that, in the embodiments of the present application, the terminal may be any device having communication and storage functions, for example: tablet computers, mobile phones, electronic readers, remote controllers, Personal Computers (PCs), notebook computers, vehicle-mounted devices, network televisions, wearable devices, and the like.
Further, in implementations of the present application, a terminal may be provided with a link structure and an NFC coil. Specifically, the NFC coil may be provided on the link structure, so that movement of the NFC coil may be achieved by driving the link structure. Wherein, the connecting rod structure can reciprocate between the upper end and the lower extreme at the terminal when driving the NFC coil and transferring.
It should be noted that, in the embodiment of the present application, since the NFC communication is dependent on communication between the NFC coils, a certain magnetic field is generated when a current flows through the NFC coils, and thus, a communication object can be identified and located by detecting real-time magnetic field data of a terminal.
It should be noted that, in the implementation of the present application, the terminal may be provided with a detection device, so that real-time detection may be performed by the detection device to obtain real-time magnetic field data. Further, the detection means may be a sensor for performing magnetic field detection. For example, fig. 5 is a schematic view of a detection device, and as shown in fig. 5, the terminal may integrate a magnetic sensor array on a battery cover, so that an external magnetic field can be detected by the magnetic sensor array in real time.
Further, in an embodiment of the present application, the real-time magnetic field data may include different magnetic field strengths corresponding to different preset positions. Specifically, one preset position corresponds to one magnetic field strength. Further, after the terminal performs real-time detection through the arranged detection device, the magnetic field strength at different preset positions corresponding to the terminal can be obtained, that is, a magnetic field strength corresponding to any one of the different preset positions can be obtained.
In the embodiment of the present application, the terminal and the communication object are both NFC-enabled communication devices each equipped with an NFC coil. In particular, the NFC coil of the terminal configuration may be moved by the link structure.
Further, in the embodiment of the present application, the middle frame is provided in the terminal, and therefore, when the terminal is provided with the link structure, the link structure may be provided on the middle frame. In particular, the middle frame is a structural component of the terminal, may be an intermediate layer as seen from the side of the terminal, and the middle frame may be a carrier for other components of the terminal. Fig. 6 is a schematic diagram of a middle frame of the terminal. As shown in fig. 6, the middle frame of the terminal may be used to carry other components in the terminal, such as a main board, a battery, an antenna platelet, etc.
And 102, determining a target area corresponding to the communication object according to the real-time magnetic field data.
In the embodiment of the application, after the terminal detects the real-time magnetic field data, the terminal may further determine a target area corresponding to the communication object according to the real-time magnetic field data. The target area may represent an optimal location for NFC with the communication object.
Further, in the implementation of the application, when the terminal determines the target area according to the real-time magnetic field data, different magnetic field strengths corresponding to different preset positions obtained through detection may be compared first, and if the different magnetic field strengths corresponding to the different preset positions are equal, it may be considered that there is no communication object that needs to be performed with NFC. If the different magnetic field strengths corresponding to the different preset positions are not equal, the terminal can determine the target magnetic field strength in the real-time magnetic field data according to a preset selection strategy; then, the target area can be determined according to the preset position corresponding to the target magnetic field intensity.
It should be noted that, in the embodiment of the present application, the terminal performs real-time detection by using the set magnetic sensor array, and if the terminal is not in contact with other NFC devices, the intensities of the magnetic fields at different positions sensed by the magnetic sensor array are the same, so that when the different magnetic field intensities corresponding to different preset positions are equal, the terminal may consider that there is no communication object that needs to perform NFC. Based on fig. 5 and fig. 7, which are schematic diagrams illustrating the detection of real-time magnetic field data, as shown in fig. 7, the terminal performs real-time detection by using the magnetic sensor array, and once the terminal contacts another NFC device, the magnetic field intensity detected by the magnetic sensor array at different preset positions is different. If the different magnetic field strengths corresponding to the different preset positions are not equal, the terminal can regard the preset position corresponding to the strongest magnetic field strength as the optimal region for performing NFC with the communication object, and the target region can be determined according to the preset position corresponding to the strongest magnetic field strength.
Further, in the embodiment of the application, when the terminal determines the target magnetic field strength in the real-time magnetic field data according to the preset selection strategy, an intensity threshold may be obtained by first calculating according to different magnetic field strengths corresponding to different preset positions, and then the target magnetic field strength is determined according to the intensity threshold; the magnetic field intensity of different magnetic field intensities corresponding to different preset positions can be sorted to obtain an intensity list, and then the target magnetic field intensity is determined according to the intensity list.
And 103, driving the connecting rod structure according to the target area to realize the movement of the NFC coil.
In the embodiment of the application, after the terminal determines the target area corresponding to the communication object according to the real-time magnetic field data, the connecting rod structure can be driven according to the target area, so that the movement of the NFC coil can be realized.
It should be noted that, in the embodiment of the application, when the terminal drives the link structure according to the target area, the moving distance corresponding to the link structure may be determined according to the target area, and then the link structure is driven according to the moving distance, so that the NFC coil may be moved by the movement of the link structure.
Further, in the practice of the present application, the terminal may also be provided with a drive means, and then the link structure is driven by the drive means. Specifically, the driving device may be a pair of motors symmetrically arranged, and the driving device may also be a pulley for pushing and pulling the connecting rod structure, and the embodiment of the present application is not particularly limited. For example, fig. 8 is a schematic view of a driving apparatus, and as shown in fig. 8, the terminal may be provided with a driving motor at symmetrical positions, respectively, for driving the link structure to move between the upper and lower ends of the terminal. Specifically, after the target area is determined, the terminal may push the link structure to move by the driving motor, so that the NFC coil may be moved into the target area by the link structure. At present, the motors dedicated for terminals mainly include a conventional vibration motor, a linear vibration motor and a voice coil motor. Among them, the conventional vibration motor may include an Eccentric Rotating Mass (ERM) motor or an Eccentric rotor motor; the Linear vibration motor moves in a reciprocating Linear motion, which is also called a Linear Resonant Actuator (LRA); the Voice Coil Motor (VCM) has the same working principle as a loudspeaker, has the characteristics of high frequency response and high precision, and has the main principle that the stretching position of a spring piece is controlled by changing the direct current of a Coil in the Motor in a permanent magnetic field so as to drive the spring piece to move up and down.
It should be noted that, in the embodiment of the application, when the terminal drives the link structure according to the target area, the moving distance corresponding to the link structure may be determined according to the target area, and then the link structure is driven according to the moving distance, so that the NFC coil may be moved into the target area.
And 104, after the NFC coil moves to the target area, performing near field communication with a communication object in the target area through the NFC coil.
In the embodiment of the application, after the terminal drives the link structure according to the target area to realize the movement of the NFC coil, after the NFC coil moves to the target area, the terminal may perform near field communication with a communication object in the target area through the NFC coil.
It should be noted that, in the embodiment of the present application, the terminal drives the NFC coil to move up and down between the upper end and the lower end of the terminal through the link structure, and until after moving to the target area, it can be considered that the NFC coil has realized the requirement of physical position alignment with the NFC coil of the communication object, so that near field communication can be performed with the communication object through the NFC coil.
Further, in the implementation of the present application, after the terminal moves the NFC coil to the target area, the NFC function may be started first, and then a connection is established with the communication object in the target area through the NFC function, so as to implement near field communication through the NFC coil.
It should be noted that, in the embodiment of the present application, the terminal may turn off the NFC function, so as to reduce power consumption.
Further, in the embodiment of the present application, after the terminal completes the near field communication between the target area and the communication object, the terminal may keep the position of the NFC coil unchanged while turning off the NFC function. Specifically, because every user's operating habit all differs with the mode of gripping, so different users correspond the effective area of NFC also not the same, so, to the same communication object, when different users operated, connecting rod structure drove NFC coil shift position in the terminal probably has certain difference, and of course, to different communication objects, when different users operated, connecting rod structure drove NFC coil shift position in the terminal probably has the unanimity. For example, when the user a performs near field communication with the communication partner a using the terminal, the coil is automatically moved to the area above the terminal using the area above the terminal. When the user a uses the terminal to perform near field communication with the information object b, the user may still use the area on the upper end of the terminal, so in order to follow the habit of the user, in the embodiment of the present application, after the terminal completes one near field communication, the position of the NFC coil may be kept unchanged while the NFC function is turned off. Of course, it is also preferable that the NFC coil in the terminal maintains the previous position for repeating the near field communication with the same communication partner.
In the embodiment of the present application, further, the design proposed in the present application, which realizes the free movement of the NFC coil by disposing the NFC coil on the connecting rod structure, may also be applied to a secondary coil on a wireless charging scheme, and the secondary coil is aligned with the primary coil in the wireless charging process.
The near field communication method provided by the embodiment of the application is applied to a terminal, the terminal comprises an NFC coil arranged on a connecting rod structure, the connecting rod structure is used for driving the NFC coil to move, and the near field communication method comprises the following steps: detecting real-time magnetic field data; wherein the real-time magnetic field data is used for identifying a communication object; determining a target area corresponding to a communication object according to the real-time magnetic field data; driving the connecting rod structure according to the target area to realize the movement of the NFC coil; and after the NFC coil moves to the target area, performing near field communication with the communication object in the target area through the NFC coil. That is to say, in the embodiment of this application, the terminal can discern the communication object according to the real-time magnetic field data that real-time detection obtained, determine can carry out near field communication's target area with the communication object, then the connecting rod structure of drive configuration, because the NFC coil sets up on connecting rod structure, therefore the NFC coil can remove to the target area through connecting rod structure, the terminal alright carry out near field communication with the communication object in the target area, and then can overcome the unable defect of communication that position misalignment leads to between terminal NFC coil and the communication object NFC coil, thereby communication efficiency is improved, the intelligence at promotion terminal.
Based on the foregoing embodiment, in another embodiment of the present application, a method for a terminal to determine a target area corresponding to a communication object according to real-time magnetic field data may include the following steps:
step 201, when different magnetic field strengths corresponding to different preset positions are unequal, determining a target magnetic field strength in real-time magnetic field data according to a preset selection strategy; the preset selection strategy is used for determining the real-time position of the communication object.
In the embodiment of the application, after detecting different magnetic field strengths corresponding to different preset positions obtained by the terminal, the terminal may compare the different magnetic field strengths, and if the different magnetic field strengths corresponding to the different preset positions are not equal, the terminal may determine the target magnetic field strength in the real-time magnetic field data including the different magnetic field strengths according to a preset selection strategy. Wherein the target magnetic field strength may be at least one of the different magnetic field strengths.
It should be noted that, in the embodiment of the present application, if the terminal does not make contact with the communication object, the different magnetic field strengths detected by the detection device configured in the terminal at the different preset positions are equal, and once the different magnetic field strengths at the different preset positions are not equal, the terminal may be considered to be in contact with the communication object, so that the target magnetic field strength may be determined among the different magnetic field strengths.
Further, in the embodiment of the present application, the preset selection policy is used to determine the real-time position of the communication object, so that the target area for performing near field communication with the communication object may be further determined according to the real-time position of the communication object. Specifically, in the embodiment of the present application, the closer the NFC coil configured by the communication object is to the terminal, the stronger the magnetic field strength is, accordingly, the terminal may consider that, among different magnetic field strengths corresponding to different preset positions, the preset position corresponding to the magnetic field strength with the strongest strength is the optimal region for performing near field communication with the communication object.
It should be noted that, in the embodiment of the present application, when the terminal determines the target magnetic field strength in the real-time magnetic field data according to the preset selection policy, the target magnetic field strength may be determined in different magnetic field strengths according to one strength threshold, or at least one magnetic field strength with the strongest strength may be directly selected as the target magnetic field strength in the different magnetic field strengths.
Step 202, determining a target area according to a preset position corresponding to the target magnetic field strength.
In the embodiment of the application, after the terminal determines the target magnetic field strength in the real-time magnetic field data according to the preset selection strategy, the target area can be determined according to the preset position corresponding to the target magnetic field strength.
It should be noted that, in the embodiment of the present application, exactly at a position where the terminal and the communication object are closer to each other, the strength of the magnetic field is stronger correspondingly, so that after the terminal determines a target magnetic field strength with a higher strength among different magnetic field strengths, the target area for performing the near field communication may be determined according to a preset position corresponding to the target magnetic field strength.
Further, in the implementation of the present application, since the target magnetic field strength may be at least one of different magnetic field strengths, and thus the target magnetic field strength corresponds to at least one of different preset positions, the terminal may determine the target area according to the at least one position corresponding to the target magnetic field strength. That is, the target region is a region including a preset position corresponding to the target magnetic field strength.
In an embodiment of the present application, further, the method for determining the target magnetic field strength in the real-time magnetic field data by the terminal according to the preset selection policy may include the following steps:
and 301, determining an intensity threshold according to different magnetic field strengths.
And step 302, determining the magnetic field intensity larger than the intensity threshold value in the real-time magnetic field data as the target magnetic field intensity.
In the implementation of the application, if different magnetic field strengths corresponding to different preset positions are not equal, the terminal can determine the strength threshold value according to the different magnetic field strengths, then compare the different magnetic field strengths in the real-time magnetic field with the strength threshold value, and finally determine the magnetic field strength larger than the strength threshold value as the target magnetic field strength.
Further, in the implementation of the present application, when determining the intensity threshold according to different magnetic field strengths, the terminal may perform average calculation on the different magnetic field strengths, and set the average of the different magnetic field strengths as a light threshold.
