Description

Near field communication control system, operation method thereof, and electronic device Technical Field

[0001] The present invention relates to the field of near field communication, and in particular to a near field communication control system, an operating method thereof, and an electronic device. Background Art

[0002] Near Field Communication (NFC) is a short-range radio frequency wireless communication technology that enables data exchange between devices at distances of ten centimeters (cm) or less. When an NFC card (NFC card) is within the magnetic field of an electronic device with an NFC reader enabled, radio frequency wireless technology establishes radio communication between the NFC reader and the NFC card. Specific application scenarios for NFC include access control card swiping and subway or bus card swiping.

[0003] Near field communication (NFC) devices include three working modes: reader mode, emulation card mode, and peer-to-peer mode. In reader mode, the NFC device can act as a card reader, emitting a radio frequency magnetic field to identify and read and write information from other NFC devices or tags. In card emulation mode, the NFC device can be simulated into a card, such as a bus card, bank card, or access card. When an NFC card is close to an NFC-enabled card reader, it will receive a signal from the card reader, and after a series of verification operations, it will transmit the corresponding information of the NFC card back to the NFC card reader. In peer-to-peer mode, both NFC devices can actively emit a radio frequency field to establish peer-to-peer communication.

[0004] Card reader and card emulation are two common NFC functions. In some commercial applications, NFC devices are often configured as card readers. A common commercial application scenario involves the need to quickly read and write a large number of different NFC card types. When faced with the need to read a large number of NFC cards in a short period of time, ensuring accurate recognition of NFC cards using the NFC reader function becomes a technical challenge.

[0037] The embodiments of the present application describe a near field communication control system, an operating method thereof, and an electronic device.

[0038] Figure 1 is a schematic diagram of the composition of a near field communication control system according to an embodiment of the present application. Figure 2 is a schematic diagram of the composition of a near field communication control system according to an embodiment of the present application.

[0039] Referring to Figures 1 and 2 , NFC control system 100 includes NFC circuit module 101 and NFC switching control module 102. NFC circuit module 101 operates in card reader mode. NFC circuit module 101 and NFC switching control module 102 are electrically connected to enable data and command transmission.

[0040] In some embodiments, the near-field communication circuit module 101 is configured to perform the following operations: Step 301: emitting a corresponding radio frequency identification signal S1 based on a universal radio frequency signal parameter configuration file; Step 302: receiving a radio frequency return signal S2 when a near-field communication card 201 approaches and emits a radio frequency return signal; Step 303: outputting radio frequency status parameters corresponding to the near-field communication card 201 based on the radio frequency return signal. The near-field communication card (NFC card) 201 is, for example, a physical card or an electronic card.

[0041] The near field communication switching control module 102 is configured to perform the following operations: Step 304 : adjust the universal radio frequency signal parameter configuration file based on the radio frequency state parameters.

[0042] In some embodiments, adjusting the universal RF signal parameter profile based on the RF state parameter includes: switching the universal RF signal parameter profile to a RF signal parameter profile with a first gain range when it is determined that the RF gain value included in the RF state parameter is greater than or equal to a first gain threshold, and switching the universal RF signal parameter profile to a RF signal parameter profile with a second gain range when it is determined that the RF gain value included in the RF state parameter is less than or equal to a second gain threshold.

[0043] The first gain threshold is, for example, greater than the second gain threshold, and the lower limit value of the first gain range is, for example, greater than the upper limit value of the second gain range.

[0044] The first gain range RF signal parameter configuration file, the second gain range RF signal parameter configuration file, or the universal RF signal parameter configuration file includes different RF signal characteristic parameters, such as different gain ranges for emitting RF reading signals. The first gain range RF signal parameter configuration file, the second gain range RF signal parameter configuration file, or the universal RF signal parameter configuration file is, for example, a .blk format file.

[0045] In some embodiments, the near-field communication circuit module 101 is further configured to perform the following operations: Step 406: Based on the switched first gain range RF signal parameter profile or the second gain range RF signal parameter profile, a corresponding RF reading signal is emitted. By emitting a corresponding RF reading signal based on the switched first gain range RF signal parameter profile or the second gain range RF signal parameter profile, data carried by NFC cards with different RF characteristics (e.g., different NFC cards with different signal transmission and reception characteristics and anti-interference characteristics) can be read, thereby improving the effectiveness of NFC card reading.

[0046] In some numerical embodiments, the first gain threshold is, for example, 30 dB (decibels). The second gain threshold is, for example, 50 dB. The first gain range includes, for example, 18 - 29 dB. The second gain range includes, for example, 51 - 60 dB. The first gain range can also be referred to as the low gain range, and the second gain range can also be referred to as the high gain range.

[0047] The RF state parameter includes an RF gain value which is obtained, for example, by converting based on the gain ratio of the characterization parameters of the RF return signal and the RF reading signal. The conversion process includes, for example, dimension conversion or unit conversion. The characterization parameter includes, for example, the amplitude of the RF return signal or the RF reading signal.

[0048] The near - field communication switching control module 102 is further configured to perform the following operations, for example: Before switching the general RF signal parameter profile to the first - gain - range RF signal parameter profile or the first - gain - range RF signal parameter profile, close the near - field communication service application supported by the near - field communication circuit module 101 through the instruction operation of the middleware 221. The near - field communication service application runs, for example, in the application layer 214.

[0049] In some embodiments, the RF state parameter further includes an Automatic Gain Control (AGC) parameter; the near - field communication switching control module 102 is further configured to perform the following operations: Step 501, when it is determined that the automatic gain control parameter is greater than or equal to the third parameter threshold, reduce the RF excitation voltage value when emitting the RF reading signal; Step 502, when it is determined that the automatic gain control parameter is less than or equal to the fourth parameter threshold, increase the RF excitation voltage value when emitting the RF reading signal. The third parameter threshold is greater than the fourth parameter threshold, for example.

[0050] In some embodiments, after the Automatic Gain Control (AGC) parameter undergoes unit conversion, the reference numerical range is, for example, 600 < AGC < 750. The third parameter threshold is, for example, 750, and the fourth parameter threshold is, for example, 600. Then, when the automatic gain control parameter is greater than or equal to 750, reduce the RF excitation voltage value (which can also be referred to as the DC - DC voltage value) when emitting the RF reading signal. When the automatic gain control parameter is less than or equal to 600, increase the RF excitation voltage value when emitting the RF reading signal.

[0051] The first - gain - range RF signal parameter profile, the second - gain - range RF signal parameter profile, and the general RF signal parameter profile include, for example, the distribution interval of the RF excitation voltage value and different values within the interval. The distribution interval of the RF excitation voltage value is, for example, 3V - 5V (volts). Different values of the RF excitation voltage include, for example, values such as 3.3V, 3.6V, 4.5V, 4.8V, etc.

[0052] When the near-field communication circuit module sends a corresponding RF reading signal based on the switched first gain range RF signal parameter profile or the second gain range RF signal parameter profile, it can select a corresponding RF excitation voltage value based on the distribution interval of the RF excitation voltage value included in the first gain range RF signal parameter profile or the second gain range RF signal parameter profile and the different values ​​within the interval, as well as the correspondence between the RF excitation voltage value and the automatic gain control parameter, and send a RF reading signal based on the selected RF excitation voltage value.

[0053] In some embodiments, step 304 can be further configured as follows: when it is determined that the RF gain value included in the RF state parameter is greater than or equal to the first gain threshold and the number of consecutive occurrences exceeds the fifth threshold number, the general RF signal parameter profile is switched to the first gain range RF signal parameter profile.

[0054] When it is determined that the RF state parameter includes a RF gain value less than or equal to the second gain threshold, the number of consecutive occurrences exceeds a sixth threshold number of times, switching the general RF signal parameter profile to a RF signal parameter profile in the second gain range. The fifth threshold number of times. For example, the fifth threshold number of times or the sixth threshold number of times is, for example, 3, 5, 6, or 8 times.

[0055] In some embodiments, the near-field communication switching control module 102 is further configured to restart the near-field communication service application supported by the near-field communication circuit module 101 through an instruction operation of the middleware 221 after the general RF signal parameter profile is switched to the first gain range RF signal parameter profile or the first gain range RF signal parameter profile. The near-field communication service application runs, for example, in the application layer 214.

[0056] The middleware 221 is distributed in the hardware abstraction layer 212 and the application framework layer 213. The near field communication control system further includes a kernel layer 211.

[0057] The present application also provides an operating method of a near field communication control system.

As shown in Figure 3, the operating method of the near-field communication control system includes: Step 301, emitting a corresponding RF reading signal based on a universal RF signal parameter configuration file; Step 302, receiving a RF return signal when a near-field communication card approaches and emits a RF return signal; Step 303, outputting RF status parameters corresponding to the near-field communication card based on the RF return signal; and Step 304, adjusting the universal RF signal parameter configuration file based on the RF status parameters.

[0059] In some embodiments, when it is determined that the RF gain value included in the RF state parameters is greater than or equal to the first gain threshold, the general RF signal parameter profile is switched to the first gain range RF signal parameter profile; when it is determined that the RF gain value included in the RF state parameters is less than or equal to the second gain threshold, the general RF signal parameter profile is switched to the second gain range RF signal parameter profile.

[0060] The first gain threshold is, for example, greater than the second gain threshold, and the lower limit value of the first gain range is, for example, greater than the upper limit value of the second gain range.

[0061] FIG4 is a flowchart of an operating method of a near-field communication control system according to another embodiment of the present application. In some embodiments, referring to FIG4 , the operating method of the near-field communication control system, in addition to steps 401 to 404 similar to steps 301 to 304, further includes step 405, which emits a corresponding radio frequency reading signal based on the switched radio frequency signal parameter profile of the first gain range or the switched radio frequency signal parameter profile of the second gain range.

In other embodiments, referring to FIG6 , the operation method of the near field communication control system according to the present application may also include steps 601 to 606 , and the specific implementation steps are shown in FIG6 .

[0063] In some embodiments, the operation method of the near-field communication control system also includes: after the general RF signal parameter profile is switched to the first gain range RF signal parameter profile or the first gain range RF signal parameter profile, restarting the near-field communication service application supported by the near-field communication circuit module through the instruction operation of the middleware.

[0064] By sending a corresponding RF reading signal based on the switched first gain range RF signal parameter profile or the second gain range RF signal parameter profile, the data carried by NFC cards with different RF characteristics (for example, different NFC cards have different signal receiving and transmitting characteristics and anti-interference characteristics) can be read, thereby improving the effectiveness of NFC card reading.

[0065] The near-field communication control system and operation method of the present application adopt different radio frequency signal parameter configuration files for NFC cards with different characteristics and send corresponding radio frequency reading signals, thereby reading data carried by NFC cards with different radio frequency characteristics, including the signal receiving and transmitting characteristics and anti-interference characteristics of different NFC cards, improving the reading ability and effectiveness of NFC cards and significantly reducing the situation where NFC cards cannot be recognized.

[0066] The technical solution of the present application realizes the operation state adjustment of the near-field communication control system without the user's awareness, meets the different card reading requirements of users during the system operation, improves the applicability of the system operation, and thus enhances the user experience.
