Therefore, in actual application scenarios, based on the performance of a detected external communication signal on a certain parameter, it is possible to distinguish which communication function the current communication signal corresponds to and which communication function needs to be enabled. One or several first antennas 14 .

The parameters of the external communication signal detected by the signal detection unit 122 may be one or more of at least one parameter that is different in the communication signals corresponding to different communication functions, for example, the communication signals corresponding to different communication functions exist in frequency If there is an obvious difference, the detection parameter can be frequency, that is, the target first antenna that needs to be enabled in the current scenario can be determined by detecting the frequency of the external communication signal; another example, communication signals corresponding to different communication functions have obvious differences in frequency and power. difference, the detection parameter can be frequency and/or power, that is, the target first antenna that needs to be enabled in the current scenario can be determined by detecting the frequency and/or power of the external communication signal; also for example, in communication signals corresponding to different communication functions Some have obvious differences in frequency, and some have obvious differences in power, then the detection parameters can be frequency and power, that is, the target first antenna that needs to be activated in the current scenario can be accurately determined by combining the frequency and power of external communication signals . That is to say, the specific parameters to be detected can be reasonably selected according to the parameters of the communication signals corresponding to the communication functions actually configured by each first antenna 14 .

Parameters for detecting external communication signals. Specifically, according to actual conditions, the detection parameters may include one or more of frequency, power, signal strength, and waveform. Of course, the detection parameters may also include other parameters capable of distinguishing communication signals of different communication functions.

Optionally, the parameters include a plurality of frequency, power, signal strength and waveform;

Through this embodiment, various parameters of the external communication signal can be detected to ensure that the communication function corresponding to the external communication signal can be more comprehensively and accurately distinguished, and the corresponding signal detection unit can be used to complete the detection according to the parameters that need to be detected The detection of external communication signals ensures the flexibility and reliability of signal detection methods.

In the embodiment of the present application, since each first antenna 14 selects the antenna path matching the current usage scenario and enters the working state by switching the switch 11, so that in the scenario of using a certain communication function, there is only one first antenna or Some of the first antennas are activated, thereby ensuring that the antenna paths corresponding to different communication functions do not interfere with each other, thereby improving antenna performance. Therefore, it is allowed to arrange N first antennas 14 in the same physical space. For example, when the antenna switching device 100 is arranged in an electronic device, the N first antennas 14 can be arranged in the same physical space in the electronic device. space.

That is to say, optionally, the N first antennas 14 are integrated and arranged in the same module.

Specifically, the N first antennas 14 may be arranged superimposedly in the same physical space, or may be integrated and arranged in the same antenna module. In this way, compared with the prior art in which the coil antenna is independently configured for each communication function in the electronic device, this embodiment can greatly optimize the space used by the device by integrating multiple antenna loops for use, and can Meet the need to integrate more communication functions in a small space, for example, it can integrate 125K radio frequency identification (Radio Frequency Identification, RFID), 433MHz remote key, 868MHz RFID, wireless charging, 13.65MHz NFC and other communication functions.

Optionally, the different communication signals include one or more of a first communication signal corresponding to a remote control function, a second communication signal corresponding to a near field communication NFC function, and a third communication signal corresponding to a radio frequency identification RFID function;

The third communication signal, etc., enables the electronic device configured with the antenna switching device 100 to support one or more of the remote control function, NFC function and RFID function, and each function can realize mutual non-interference by switching independent antenna paths Work.

Moreover, in order to be able to distinguish these functions well, the working frequencies of the communication signals corresponding to these functions can be configured, so that in practical applications, the frequency of external communication signals can be detected to quickly and accurately identify the type of communication signals, and then Quickly and accurately switch to the matching antenna path to support the current communication function. Specifically, the first communication signal may be a communication signal operating at about 433MHz, the second communication signal may be a communication signal operating at about 13.56MHz, and the third communication signal may be a communication signal operating at about 125KHz. In this way, it can ensure that the frequency differences of communication signals corresponding to different communication functions are relatively large, which in turn helps to quickly identify different communication signals from the frequency, and then enables the antenna path corresponding to the corresponding communication function.

To avoid repetition, details are not repeated here.

Please refer to FIG. 2. FIG. 1 is a flow chart of the antenna switching method provided in the embodiment of the present application, which is executed by the electronic device provided in the previous embodiment. As shown in FIG. 2, the method includes the following steps:

Step 201: Receive and detect parameters of external communication signals through the signal detection module of the electronic device.

Step 202: Determine the target first antenna used to receive the target communication signal among the N first antennas of the electronic device, and determine the target communication channel among the M communication modules of the electronic device that matches the target first antenna module, wherein the target communication signal is a communication signal that matches the measured value of the detected parameter.

Step 203, select the target first antenna and the target communication module through the switching switch of the electronic device, wherein, among the N first antennas, the first antennas other than the target first antenna are not communicate with any communication module in the M communication modules.

It should be noted that this embodiment is a method embodiment corresponding to the embodiment of the antenna switching device shown in FIG. 1 , and its specific implementation manner can refer to the relevant introduction in the foregoing embodiment of FIG. 1 , which will not be repeated here.

Optionally, the step 202 includes:

According to the predefined N parameter value intervals, determine the first parameter value interval where the measured value is located, wherein the N parameter value intervals are based on the N parameters of the communication signals respectively configured by the N first antennas value determination;

determining a target communication signal whose parameter value is within the first parameter value range, and determining a target first antenna among the N first antennas for receiving the target communication signal.

That is, in one embodiment, N parameter value intervals can be obtained in advance according to the N parameter values of the communication signals respectively configured by the N first antennas, for example, the parameters of the communication signals respectively configured by the 3 first antennas The values from large to small are C ₁ , C ₂ and C ₃ , and parameter value intervals S ₁ , S ₂ and S ₃ can be set, among which, S ₁ is an interval greater than C ₁ ′, and S ₂ is greater than C ₂ ′ And less than the interval of C ₁ ′, S ₂ is the interval less than C ₂ ′, C ₁ ′ can be a value between C ₁ and C 2 , and C ₂ _′ can be a value between C ₂ and C ₃ value. Of course, the parameter value range may also be defined in other ways, as long as it is ensured that the parameter values of different communication signals can be better distinguished.

In this way, after the measured value of the external communication signal is detected, it can be determined which parameter value interval the measured value is in among the N parameter value intervals, so as to determine the first parameter value interval in which the measured value is located.

Then, based on the first parameter value interval, the target communication signal whose parameter value is in the first parameter value interval can be determined, the target communication signal is the signal matching the current external communication signal, and the N number can be further determined Among the first antennas, the first antenna used to receive the target communication signal is the target first antenna.

In this way, through this embodiment, the target first antenna that matches the current communication scene can be determined quickly and accurately by detecting the parameters of the external communication signal, and then the antenna corresponding to the target first antenna can be selected by switching the switch 11 The channel is used to ensure that the target first antenna is quickly activated and good timeliness of use is ensured.

The antenna switching method in the embodiment of the present application includes: receiving and detecting parameters of external communication signals through the signal detection module of the electronic device; determining the target for receiving the target communication signal among the N first antennas of the electronic device The first antenna, and determining a target communication module among the M communication modules of the electronic device that matches the target first antenna, wherein the target communication signal is a communication signal that matches the measured value of the detected parameter ; gating the target first antenna and the target communication module through the switch of the electronic device, wherein, among the N first antennas, the first antennas other than the target first antenna are not connected to the target first antenna Any communication module in the above M communication modules is connected. In this way, by detecting the parameters of the external communication signal, the target first antenna to be activated at present is determined, and then switched to the corresponding antenna path to receive the external communication signal, and other unrelated antenna paths are disconnected, so that the Enable corresponding antennas according to actual needs, reduce inter-antenna interference caused by simultaneous activation of multiple antennas, and improve antenna performance.

The following combines several different application scenario embodiments to illustrate the specific implementation of the embodiments of the present application:

Application Scenario 1: The frequencies of communication function A, communication function B, and communication function C are quite different, and they are distinguished directly by frequency.

When the working spectrums of communication function A, communication function B and communication function C do not intersect, the corresponding three frequencies appear as f(A)>f(B)>f(C), by detecting the frequency point of the external communication signal, that is It can judge which communication function needs to be used, and can switch to the corresponding communication loop to complete the communication.

For example, communication function A is a 433MHz remote control function, communication function B is a 13.56MHz NFC function, and communication function C is a 125K RFID function. When it is detected that the frequency of the external communication signal is above 100MHz, it can be judged as the remote control function, thereby enabling the antenna configured to realize the remote control function; when it is detected that the frequency of the external communication signal is 1-100MHz, it can be judged as the NFC function, thereby enabling it The antenna configured to realize the NFC function is configured; and when the frequency of the external communication signal is detected to be lower than 1MHz, it can be determined as the RFID function, thereby enabling the antenna configured to realize the RFID function. In this way, by switching to the corresponding antenna loop, the quality of the corresponding communication function can be improved.

Application Scenario 2: Communication function A and communication function B exhibit different drive strengths (ie, power strengths), which are differentiated and judged by signal power strengths.

Communication function A and communication function B cannot be distinguished simply by frequency, but when the signal strengths sent by external communication devices are quite different, different functions can be identified through power detection.

Specifically, the frequency of communication function A is close to that of communication function B, and the signal strength of communication function A is greater than that of communication function B. When it is detected that the signal strength induced by an external communication signal exceeds the set threshold, it can be judged as a communication function A, otherwise it is judged as communication function B.

For example, communication function A is a wireless charging function, the signal frequency is 110kHz-150kHz, and the transmission power is relatively large; communication function B is a 125K RFID function, the signal frequency is 125kHz or 134kHz, and the signal transmission drive strength and power are very small. When using wireless charging, the signal strength of the detected wireless charging signal will far exceed the signal strength of RFID, which can be used as a basis for judgment.

Application Scenario 3: Communication function A and communication function B exhibit different indicators.

In this case, as long as there is a difference between the communication signals of the two communication functions, the corresponding communication function can be judged by detecting the difference index, thereby realizing communication function adaptation.
