The radio frequency signal processing method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

As shown in fig. 1, an embodiment of the present application provides a radio frequency signal processing method, which is applied to an electronic device including a first signal processing module and a second signal processing module, and the method includes:

step 11: controlling one of the first signal processing module and the second signal processing module to be in an operating state, and controlling the other of the first signal processing module and the second signal processing module to be in a non-operating state.

Optionally, the electronic device processes a radio frequency signal of a first frequency when the first signal processing module is in a working state; the electronic device may process the radio frequency signal of the first frequency, where the first electronic device listens for the radio frequency signal of the first frequency, and the first electronic device detects the radio frequency signal of the first frequency.

Optionally, the electronic device processes the radio frequency signal of the second frequency when the second signal processing module is in an operating state. The electronic device may process the radio frequency signal of the second frequency, where the first electronic device listens for the radio frequency signal of the second frequency, and the first electronic device detects the radio frequency signal of the second frequency.

The monitoring means that the electronic equipment executes the function of simulating the radio frequency card, does not emit field intensity signals and can receive the field intensity signals; the detection means that the electronic equipment executes a card reading function and emits a field intensity signal to detect whether a radio frequency card exists or not or whether the electronic equipment simulates the radio frequency card exists.

Optionally, the first signal processing module in the non-operating state may be a state in which the radio frequency signal of the first frequency is not processed, such as the first signal processing module in an off state, or a Standby (Standby) state, and the like. The non-operating state of the second signal processing module may be a state in which the radio frequency signal of the second frequency is not processed, such as a state in which the second signal processing module is turned off or a state to be operated.

In the embodiment of the application, under the condition that the first signal processing module is controlled to be in the working state and the second signal processing module is controlled to be in the non-working state, the electronic device processes the radio frequency signal with the first frequency, that is, the first electronic device can read data of the radio frequency card with the first frequency, or read corresponding data in the electronic device simulating the radio frequency card with the first frequency, or the first electronic device can simulate the function of the radio frequency card with the first frequency; under the condition that the first signal processing module is controlled to be in a non-working state and the second signal processing module is controlled to be in a working state, the electronic device processes the radio frequency signal of the second frequency, namely the first electronic device can read data of the radio frequency card of the second frequency, or read corresponding data in the electronic device simulating the radio frequency card of the second frequency, or the first electronic device can simulate the function of the radio frequency card of the second frequency. Therefore, by switching the working states of the first signal processing module and the second signal processing module, the reading of radio frequency cards or analog cards with different frequencies can be realized, or the functions of the radio frequency cards with different frequencies can be simulated, so that the problem that the types of cards which can be simulated by the conventional electronic equipment are limited is solved.

Optionally, the number of the first signal processing modules arranged in the electronic device in the embodiment of the present application is not limited, that is, the electronic device may further include at least one third signal processing module in addition to the first signal processing module and the second signal processing module. In the case that the electronic device includes 3 or more signal processing modules, the control method is similar to the above method, and one of the signal processing modules needs to be controlled to be in the working state, and other signal processing modules are in the non-working state, which is not described herein again.

In addition, it should be noted that the embodiment of the present application can be applied to radio frequency signal processing of other frequencies besides the radio frequency signal processing of the card reading/simulating scenes of 13.56MHz and 125kHz, and the embodiment of the present application is not limited to this.

Optionally, as an implementation: the first signal processing module may be a first chip, and the second signal processing module may be a second chip;

the step of controlling one of the first signal processing module and the second signal processing module to be in an operating state and controlling the other of the first signal processing module and the second signal processing module to be in a non-operating state may specifically include:

under the condition that a first chip finishes processing a target radio frequency signal with a first frequency, controlling the first chip to be in a non-working state, and controlling a second chip to be in a working state through a first interrupt signal; the frequency of the first target radio frequency signal is a first frequency.

Or, under the condition that the second chip finishes processing the target radio frequency signal of the second frequency, controlling the second chip to be in a non-working state, and controlling the first chip to be in a working state through a second interrupt signal; the frequency of the second target radio frequency signal is a second frequency.

For example: the first chip may be an NFC chip and the second chip may be a 125kHz low frequency chip. The NFC chip can support modulation, demodulation and processing of 13.56MHz radio frequency signals, the 125kHz low-frequency chip can support modulation, demodulation and processing of 125kHz radio frequency signals, and the NFC chip and the 125kHz low-frequency chip are controlled to work cooperatively through the interrupt control signal.

Alternatively, as shown in fig. 2, the first chip 21 and the second chip 22 are both connected to a main control chip 23 in the electronic device, and the first chip 21 and the second chip 22 may be connected to the same antenna 24, that is, the first chip 21 and the second chip 22 may share the antenna, so as to implement compatibility of card reading at frequencies of 13.56MHz and 125kHz and card simulation protocols.

Optionally, the listening and probing of the 13.56MHz and 125kHz protocols are implemented by polling. For convenience of description, the NFC chip is described as supporting two protocols, namely protocol a and protocol B, and it should be understood that the NFC chip is not limited to supporting protocol a and protocol B, and may also support other protocols besides protocol a, and the embodiment of the present application is not limited thereto.

Example one: and after the NFC chip completes protocol mode polling, switching the 125kHz low-frequency chip to perform protocol mode polling.

As shown in fig. 3, a flow chart of protocol mode polling is presented. The method specifically comprises the following steps:

when the NFC chip is in a working state, monitoring of a protocol A is carried out;

after finishing the interception of the protocol A, the NFC chip carries out the interception of the protocol B;

after the NFC chip finishes the monitoring of the protocol B, the detection of the protocol A is carried out;

after the NFC chip finishes the detection of the protocol A, the detection of the protocol B is carried out;

after the NFC chip finishes the detection of the protocol B, the NFC chip enters a non-working state, and wakes up the low-frequency chip of 125kHz to be in a working state through a first interrupt signal;

when the 125kHz low-frequency chip is in a working state, monitoring a 125kHz protocol;

after the 125kHz low-frequency chip finishes the monitoring of the 125kHz protocol, detecting the 125kHz protocol;

and after finishing the detection of the 125kHz protocol, the 125kHz low-frequency chip enters a non-working state, wakes up the NFC chip to be in a working state through a second interrupt signal, and executes the step of detecting the protocol A.

Example two: the NFC chip and the 125kHz low-frequency chip perform one of protocol mode snooping and probing, and then perform the other of protocol mode snooping and probing.

As shown in fig. 4, another flow chart of protocol mode polling is presented. The method specifically comprises the following steps:

after finishing the monitoring of the protocol B, the NFC chip enters a non-working state and wakes up the low-frequency chip of 125kHz to be in a working state through a first interrupt signal;

after the 125kHz low-frequency chip finishes the monitoring of the 125kHz protocol, the low-frequency chip enters a non-working state, and the NFC chip is awakened to be in a working state through a second interrupt signal;

when the NFC chip is in a working state, detecting a protocol A;

when the 125kHz low-frequency chip is in a working state, detecting a 125kHz protocol;

Besides the above-mentioned manner to implement polling of the protocol modes of the NFC chip and the 125kHz low-frequency chip, other manners may also be adopted, such as performing interception of protocol a, interception of protocol B, interception of 125kHz protocol, detection of protocol a, detection of protocol B, and the like in sequence, which is not limited in this embodiment of the present application.

In the embodiment of the application, the NFC chip and the 125kHz low-frequency chip are controlled to work cooperatively through the interrupt signal, so that the expansion of the 125kHz protocol is realized, the realization mode is simple, whether the expansion of the 125kHz chip is added or not can be freely controlled, and the selectivity of functions is increased.

Optionally, as another implementation: the first signal processing module may be a first modem and the second signal processing module may be a second modem.

stopping power supply to the first modem and power supply to the second modem under the condition that the first modem finishes processing a third target radio frequency signal; the frequency of the third target radio frequency signal is the first frequency.

Or, when the second modem finishes processing the fourth target radio frequency signal, stopping power supply to the second modem and power supply to the first modem; the frequency of the fourth target radio frequency signal is a second frequency.

Optionally, the first modem and the second modem are located in the same chip. For example: the first modem may be a 13.56MHz modem for supporting 13.56MHz radio frequency signal modem and the second modem may be a 125kHz modem for supporting 125kHz radio frequency signal modem.

Alternatively, as shown in fig. 5, the first modem 51 and the second modem 52 may be integrated into one NFC chip 50, so that modulation and demodulation supporting radio frequency signals of 13.56MHz and 125kHz may be implemented by one NFC chip 50, thereby implementing a radio frequency card or an analog card supporting reading and analog of 13.56MHz and 125 kHz.

Specifically, a low frequency card protocol of 125kHz may be added to the NFC protocol in the software logic of the NFC controller, for example: the 125kHz protocol is used as an extended protocol of the NFC protocol, so that the compatibility of the NFC protocol and the 125kHz low-frequency card protocol can be realized by means of an NFC protocol stack and an upper-layer framework, and the similar process to the reading and simulation of the NFC card is ensured when the 125kHz radio-frequency card or the simulation card is read and simulated, so that the use by a user is facilitated, and the seamless compatibility is realized.

Alternatively, the reading and simulating of 13.56MHz and 125kHz radio frequency cards or analog cards is achieved by polling for listening and probing. For example: the high frequency protocol corresponding to 13.56MHz includes protocol a, protocol B, protocol C, and the low frequency protocol corresponding to 125kHz includes the 125kHz protocol.

As shown in fig. 6, the process of polling for listening and probing may include: according to protocol A interception, protocol B interception, protocol C interception, protocol A detection, protocol B detection, protocol C detection, 125kHz protocol detection and 125kHz protocol interception, and the loop execution is carried out.

In polling snooping and probing, when a 125kHz protocol is polled (e.g., after probing of protocol C is performed), the power-down of the 13.56MHz modem is controlled to be off, and the power-up of the 125kHz modem is controlled to be on by stopping the power supply of the 13.56MHz modem to perform 125kHz protocol snooping or probing.

When the protocol of 13.56MHz is polled (such as after 125kHz protocol snooping is executed), the power-off of the 125kHz modem is controlled by stopping the power supply of the 125kHz modem, and the power supply of the 13.56MHz modem is controlled by controlling the power-on of the 13.56MHz modem, so as to execute protocol snooping or probing of 13.56 MHz.

Optionally, the order of snooping and probing of the 13.56MHz protocol and the 125kHz protocol is not limited to the above embodiments, and may also be according to, for example, protocol a snooping, protocol B snooping, protocol C snooping, 125kHz protocol probing, protocol a probing, protocol B probing, protocol C probing, loop execution, etc., which is not limited to this embodiment of the present application.

Alternatively, the 125kHz modem and the 13.56MHz modem may be controlled by the NFC controller to be powered down or powered up.

According to the embodiment of the application, a 125kHz modem is added in an NFC chip, and switching of different frequency protocols is achieved through power-on and power-off control of the corresponding modem. On the basis of utilizing the existing NFC hardware and partial software architecture, the card reading and simulating function of 125kHz is realized. The support types of the radio frequency card or the analog card copying are expanded, and the use experience of a user is improved.

Optionally, the step of controlling one of the first signal processing module and the second signal processing module to be in an operating state and controlling the other of the first signal processing module and the second signal processing module to be in a non-operating state may specifically include:

under the condition that the first signal processing module finishes monitoring and detecting a fifth target radio frequency signal, controlling the first signal processing module to be in a non-working state and controlling the second signal processing module to be in a working state; the frequency of the fifth target radio frequency signal is the first frequency.

Or, under the condition that the second signal processing module finishes monitoring and detecting a sixth target radio frequency signal, controlling the first signal processing module to be in a working state and controlling the second signal processing module to be in a non-working state; the frequency of the sixth target radio frequency signal is a second frequency.

For example: the first signal processing module can be a processing module for supporting 125kHz protocol interception and detection, the second signal processing module can be a processing module for supporting 13.56MHz protocol interception and detection, and by organizing the 125kHz protocol interception and detection together, the 125kHz modem is controlled to be powered on, the 13.56MHz modem is controlled to be powered off, after the 125kHz protocol interception and detection are carried out, the 125kHz modem is switched off, the 13.56MHz modem is switched on, and the 13.56MHz protocol interception or detection is carried out, so that the switching times of the modems are reduced, and the system performance is improved.

Optionally, in addition to the polling listening manner, in the embodiment of the present application, according to a user input, one of the first signal processing module and the second signal processing module may be controlled to be in an operating state, and the other of the first signal processing module and the second signal processing module may be controlled to be in a non-operating state, which specifically includes the following steps:

receiving a fourth input from the user;

and responding to the fourth input, controlling the first signal processing module to be in a closed state, and controlling the second signal processing module to be in a working state.

Or,

receiving a fifth input of the user;

and responding to the fifth input, controlling the first signal processing module to be in a working state, and controlling the second signal processing module to be in a closing state.

For example: the second signal processing module may be a 125kHz signal processing module, the user needs the electronic device to read 125kHz radio frequency card or analog card data, the user may perform a card copying operation (e.g. a predetermined input, or an operation for a copy button in an application interface), and the electronic device may switch the 125kHz signal processing module to be in an operating state when receiving the card copying operation of the user. Or, when the user needs the electronic device to simulate the 125kHz simulated card function, the user may perform a card switching operation (such as a predetermined input, or an operation for a target card in an application interface), and when the electronic device receives the card switching operation of the user, the electronic device may switch to the operating state of the 125kHz signal processing module, so that data of the target card interacts with the target device.

For another example: the second signal processing module may be a 13.56MHz signal processing module, the user needs the electronic device to read data of a 13.56MHz radio frequency card or an analog card, the user may perform a card copying operation (such as a predetermined input, or an operation for a copy button in an application interface), and when the electronic device receives the card copying operation of the user, the electronic device may switch to the 13.56MHz signal processing module to be in an operating state. Or, when the user needs the electronic device to simulate the 13.56MHz simulated card function, the user may perform a card-cutting operation (such as a predetermined input, or an operation for a target card in an application interface), and when the electronic device receives the card-cutting operation of the user, the electronic device may switch the 13.56MHz signal processing module to be in a working state, so that data of the target card interacts with the target device.

Optionally, the step of controlling one of the first signal processing module and the second signal processing module to be in an operating state and controlling the other of the first signal processing module and the second signal processing module to be in a non-operating state may further specifically include:

receiving a first input of a user;

responding to the first input, controlling the first signal processing module to be in a working state, controlling the second signal processing module to be in a non-working state, and displaying a first interface corresponding to the electronic equipment for processing the radio-frequency signal with the first frequency;

and under the condition of exiting the first interface, controlling the first signal processing module to be in a non-working state and controlling the second signal processing module to be in a working state.

For example: the first signal processing module may be a signal processing module supporting 13.56MHz, and the second signal processing module may be a signal processing module supporting 125 kHz. The following description is taken by taking a 13.56MHz modem as a 13.56MHz signal processing module and a 125kHz modem as a 125kHz signal processing module as an example:

the signal processing module of 13.56MHz is enabled by default (namely, the modem of 13.56MHz is powered on and the modem of 125kHz is powered off in the initial state), and when the card reading and simulating functions of 125kHz are switched to be used, the modem of 13.56MHz is powered off and the modem of 125kHz is powered on.

Further, when the 13.56MHz signal processing module is switched to be used again, the 13.56MHz modem is powered on, and the 125kHz modem is powered off; or when the card reading and simulating functions of 125kHz are quitted (such as quitting the first interface), the signal processing module of 13.56MHz is automatically switched on, namely, the modem of 13.56MHz is automatically powered on, and the modem of 125kHz is powered off.

Specific examples are: when the user uses the 125kHz radio frequency signal processing function in a specific function (as shown in figure 7, the user selects to copy a 125kHz entrance guard card, or as shown in figure 8, the user selects to use a 125kHz ID card for swiping the card), the 125kHz modem is powered on, and the 13.56MHz modem is powered off.

Further, when the user finishes exiting the corresponding interface by using the 125kHz card reading or analog card function, or switches to use the 13.56MHz radio frequency signal processing function (as shown in fig. 9, the user selects to switch to use the NFC analog card, i.e., the 13.56MHz analog card, such as an NFC access card), the 13.56MHz modem is powered on, and the 125kHz modem is powered off.

Optionally, a card icon currently in an activated state may be set to top for display in the card management interface, so that a user can know the card currently in the activated state, for example, when the user selects the 125kHz ID card for swiping the card in fig. 8, the icon of the 125kHz ID card is set to top for display; when the user selects to use the NFC access card, the icon of the NFC access card is displayed on the top.

Optionally, in this embodiment of the present application, a mode of controlling a clock generator and a sampling frequency of a modem by software may also be used to implement modulation and demodulation of signals compatible with 13.56MHz frequency and 125kHz frequency by using one modem, which is not limited to this embodiment of the present application.

receiving a second input of the user;

responding to the second input, controlling the first signal processing module to be in a non-working state, controlling the second signal processing module to be in a working state, and displaying a second interface corresponding to the electronic equipment for processing the radio-frequency signal with the second frequency;

and under the condition of exiting the second interface, controlling the first signal processing module to be in a working state and controlling the second signal processing module to be in a non-working state.

the 125kHz signal processing module is enabled by default (namely the 125kHz modem is powered on and the 13.56MHz modem is powered off in the initial state), and when the functions of reading and simulating the card with 13.56MHz are switched to use, the 125kHz modem is powered off and the 13.56MHz modem is powered on.

Further, when the 125kHz signal processing module is switched to be used again, the 125kHz modem is powered on, and the 13.56MHz modem is powered off; or when the card reading and simulating functions of 13.56MHz are quitted (such as quitting the second interface), the signal processing module of 125kHz is automatically switched on, namely, the modem of 125kHz is automatically powered on, and the modem of 13.56MHz is powered off.

Optionally, the method of the embodiment of the present application may further include at least one of:

and displaying first prompt information under the condition of intercepting a first radio frequency signal sent by first equipment, wherein the first prompt information is used for indicating that the first equipment is equipment corresponding to the first frequency.

For example, the description is made in conjunction with a card reading scenario: when a user uses the electronic equipment to read a card, if a radio frequency card or an analog card of 125kHz is detected, displaying first prompt information; alternatively, the first prompt message may be a tag for prompting the detection of the 125kHz radio frequency card or analog card, as shown in fig. 10, so that the user can know the type of the currently detected radio frequency card or analog card.

Optionally, in the case that the prompt indicates that the tag of the 125kHz radio frequency card is detected, a selection interface may be further displayed, which is provided for selecting an application program corresponding to the currently identified 125kHz radio frequency card.

And displaying second prompt information under the condition of intercepting a second radio frequency signal sent by second equipment, wherein the second prompt information is used for indicating that the second equipment is equipment corresponding to the second frequency.

For example, the description is made in conjunction with a card reading scenario: when a user uses the electronic equipment to read a card, if a radio frequency card or an analog card of 13.56MHz is detected, displaying first prompt information; optionally, the first prompt message may be a tag for prompting detection of a 13.56MHz radio frequency card or an analog card.

Under the condition that a third radio frequency signal sent by third equipment is intercepted, target card data corresponding to the third equipment is copied, and a copy interface of the target card data is displayed; the target card data is data of a radio frequency card, or the target card data is data of an analog card in the third device.

In this embodiment, for the convenience of the user, if the radio frequency card or the analog card of 125kHz is detected, the user can directly jump to the copy page and copy the radio frequency card data or the analog card data, so as to realize the quick and convenient copy of the radio frequency card or the analog card.

It should be noted that, in the embodiment of the present application, the radio frequency card may refer to a physical card: for example, the analog card may refer to an analog card that simulates a function of a corresponding card by copying data of the corresponding radio frequency card or writing data of the corresponding radio frequency card in the electronic device.

Optionally, the method may further include:

receiving a third input of the user;

responding to the third input, and displaying a card icon corresponding to at least one simulation card;

the card icon mark is used for indicating identification information of the type of the analog card, and the type of the analog card is a first frequency type or a second frequency type.
