[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0035] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0036] It should be pointed out that the terms "first\second\third" involved in the embodiments of the present application are used to distinguish similar or different objects, and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0037] In order to more clearly explain the power detection method provided in the embodiment of the present application, the structure of the terminal device to which the method is applied is explained below.

[0038] Figure 1 For a schematic diagram of the structure of the terminal device provided in the embodiment of the present application, please refer to Figure 1 The power detection method provided in the embodiment of the present application can be applied to terminal devices, which may include but are not limited to mobile phones, wearable devices (such as smart watches, smart bracelets, smart glasses, etc.), tablet computers, laptops, vehicle terminals, PCs (Personal Computers), etc. The functions implemented by the method can be implemented by calling program codes by a processor in an electronic device. Of course, the program codes can be stored in a computer storage medium. It can be seen that the terminal device at least includes a processor and a storage medium.

[0039] In one embodiment, the terminal device includes: at least two transceivers 110 , a control switch 120 , and a detection circuit 130 ; the at least two transceivers 110 are connected to the control switch 120 , and the control switch 120 is connected to the detection circuit 130 .

[0040] Among them, the transceiver 110 can be a device in the terminal device for sending and receiving signals. During the interaction between the terminal device and other devices, the transceiver 110 can actively send signals to other devices, or receive signals sent by other devices through the transceiver 110.

[0041] It should be noted that the terminal device may include at least two transceivers. For example, if there are two transceivers, the two transceivers may be a high-frequency transceiver and a medium-low-frequency transceiver respectively; if there are three transceivers, the three transceivers may be a high-frequency transceiver, a medium-frequency transceiver and a low-frequency transceiver respectively, where the actual frequency range defined by the high frequency, medium frequency and low frequency can be set according to actual needs, and no specific restrictions are made here.

[0042] The control switch 120 may be a single-pole double-throw switch, and may include two input terminals and one output terminal. The two input terminals may be connected to any two transceivers 110 , respectively, and the output terminal may be connected to the detection circuit 130 .

[0043] It should be noted that, when it is necessary to detect the power of a signal sent by one of the transceivers 110 , the control switch 120 may be switched to be connected to the transceiver 110 , thereby achieving circuit connection.

[0044] The detection circuit 130 may be a power detection path for the signal sent by the transceiver, for example, it may be a MRX (Monitoring Receiver) or a FBRX (Feedback Receiver).

[0045] The signal sent by the transceiver 110 may be transmitted to the detection circuit 130 through the control switch 120 , and the detection circuit 130 may determine the power of the signal after receiving the signal.

[0046] It should be noted that during the process of performing signal detection on any one of the multiple transceivers 110, if another transceiver connected to the control switch 120 is also in a signal transmission state, it may affect the signal sent by the transceiver performing signal detection, for example: in the case of double signal transmission, the power detection may not be accurate enough.

[0047] In order to solve the above problem and increase the isolation of the signals sent by the two transceivers, the technical means adopted in the related art is to replace the above control switch 120 with other switches with higher isolation, such as a single-pole four-throw switch. However, adopting this method will lead to an increase in the cost of the terminal equipment.

[0048] A power detection method is provided in an embodiment of the present application, which can improve the isolation between multiple signals without changing the hardware structure and ensure the accuracy of power detection. The specific implementation process of the power detection method provided in the embodiment of the present application is explained below.

[0049] Figure 2 Please refer to the flowchart of the power detection method provided in the embodiment of the present application. Figure 2 , the method comprising:

[0050] S210: A target transceiver among at least two transceivers sends a control signal to another transceiver.

[0051] The execution subject of the method may be the above terminal device. The target transceiver may be the transceiver that needs to perform power detection among the at least two transceivers, the target transceiver may be connected to the control switch, and the other transceiver is another transceiver connected to the control switch.

[0052] For example, if the terminal device includes transceiver A and transceiver B, both transceiver A and transceiver B are connected to the control switch. If it is necessary to detect the power of the signal transmitted by transceiver A, transceiver A is the target transceiver and transceiver B is the other transceiver. Conversely, if it is necessary to detect the power of the signal transmitted by transceiver B, transceiver B is the target transceiver and transceiver A is the other transceiver.

[0053] It should be noted that the working mode of each transceiver includes: normal mode or isolation mode.

[0054] The device isolation of the transceiver in the isolation mode is greater than the device isolation of the transceiver in the normal mode.

[0055] Device isolation refers to the isolation between signals output through two output ports of the device. For example, device isolation can be 30db.

[0056] Each transceiver may have a corresponding working mode. Under normal circumstances, it may be in a normal mode. When the transceiver is triggered by a control signal, it may be changed from the normal mode to the isolation mode.

[0057] Optionally, the control signal is used to control another transceiver to start an isolation mode.

[0058] For example, if transceiver A sends a control signal to transceiver B, transceiver B can start the isolation mode; correspondingly, if transceiver B sends a control signal to transceiver A, transceiver A can start the isolation mode.

[0059] It should be noted that a coupler may be provided in the PAMID (Power Amplifier and Module in Package) of each transceiver, and the coupler may have a high sensitivity mode (HISO MODE). When the coupler is in high sensitivity mode, the transceiver may be in isolation mode.

[0060] That is to say, the target transceiver can control the coupler in another transceiver to turn on the high sensitivity mode through the control signal, thereby turning on the isolation mode of the other transceiver. When the isolation mode of the other transceiver is turned on, the isolation of the device can be improved.

[0061] S220: When the other transceiver is in the isolation mode, the detection circuit performs power detection on the target transceiver.

[0062] It should be noted that when the other transceiver is in isolation mode, the impact between the signals sent by the target transceiver and the other transceiver in the terminal device will be reduced. In this case, the detection circuit can perform power detection on the target transceiver, that is, obtain the signal sent by the target transceiver and determine the power of the signal.

[0063] Among them, since the other transceiver is in isolation mode, there is a high degree of isolation between the target transceiver and the other transceiver, and the signals sent by the two will not affect each other. Even if the target transceiver and the other transceiver transmit signals at the same time, it will not affect the signal power detection of the detection circuit.

[0064] In the power detection method provided in the embodiment of the present application, a target transceiver among at least two transceivers may send a control signal to another transceiver, and the control signal is used to control the other transceiver to start an isolation mode; when the other transceiver is in the isolation mode, a detection circuit performs power detection on the target transceiver, wherein the isolation mode is turned on by the control signal to improve the device isolation of the other transceiver, thereby avoiding the influence of the power of the signal sent by the other transceiver during the power detection of the target transceiver, and improving the isolation between multiple signals without changing the hardware structure, thereby ensuring the accuracy of power detection.

[0065] Let's combine Figure 1 The structure of the terminal device in the embodiment of the present application is used to explain the implementation process of power detection on the terminal device.

[0066] Figure 3 For the work flow diagram of power detection of the terminal device provided in the embodiment of the present application, please refer to Figure 3 ,exist Figure 3 In the example, the target transceiver can be a B1 transceiver, and the other transceiver can be an N78 transceiver. Take the power detection of the B1 transceiver as an example:

[0067] Among them, the B1 transceiver can send a control signal to the N78 transceiver, so that the N78 transceiver can start the isolation mode.

[0068] For example, Figure 3 Taking the process shown in as an example, the power calculation is as follows:

[0069] The feedback power P of B1 detected by the detection circuit B1 for:

[0070] P B1 =P1-A B1 ;

[0071] The switch coupling power P of N78 received by the detection circuitN78 for:

[0072] P N78 =P2-A N78 -A0-A S ;

[0073] Among them, P1 is the theoretical value of the signal transmission power of B1, P2 is the theoretical value of the signal transmission power of N78, and A B1 is the device isolation of B1 transceiver, A N78 is the device isolation of the N78 transmitter, A S is the device isolation of the control switch, and A0 is the increased isolation in isolation mode.

[0074] Assume that if the device isolation of each transceiver is 30db, the device isolation of the control switch is 25db, the isolation mode of the transceiver will increase the isolation by 30db, the theoretical value of the signal transmission power of the B1 transceiver is 10dbm, and the theoretical value of the signal transmission power of the N78 transceiver is 20dbm, then the calculation results are as follows:

[0075] P B1 =10dbm-30db=-20dbm;

[0076] P N78 =20dbm-30db-25db-30db=-65dbm;

[0077] In actual calculation, if the switch coupling power of N78 received by the detection circuit is less than -50dbm, it can be determined that N78 has no effect on B1, and -65dbm<-50dbm, therefore, it can be determined that the transmit power of the N78 transceiver will not affect the transmit power of B1.

[0078] In order to more clearly explain the working principle of the isolation mode, the structural relationship of the internal path of the transceiver provided in the embodiment of the present application is explained below.

[0079] Figure 4 For a schematic diagram of the internal path of the transceiver provided in the embodiment of the present application, please refer to Figure 4 The transceiver includes two output ends, each output end corresponds to a signal transmission path, wherein the physical interval between the signal transmission paths corresponding to the two output ends of the transceiver in the normal mode is smaller than the physical interval between the signal transmission paths corresponding to the two output ends in the isolation mode.

[0080] It should be noted that in the transceiver, multiple transmission paths can be preset. In the actual implementation process, if the transmission paths selected by the two output ends are physically close, there may be a problem of signal leakage, so the isolation is low. This situation is also the normal mode of the above-mentioned transceiver; if the transmission paths selected by the two output ends are physically far apart, the signal leakage is low, so the isolation will be improved. This situation is also the isolation mode of the above-mentioned transceiver.

[0081] Figure 4 In the example, three paths are used as an example. It should be noted that each output end of the transceiver can correspond to a transmission path. This transmission path can be selected, for example, from Figure 4 Choose any two paths from the three paths.

[0082] If transmission path 1 and transmission path 2 are selected, or transmission path 2 and transmission path 3 are selected, the physical interval between the signal transmission paths corresponding to the two output ends of the transceiver is smaller, in which case the transceiver can be in normal mode; if transmission path 1 and transmission path 3 are selected, the physical interval between the signal transmission paths corresponding to the two output ends of the transceiver is larger, in which case the transceiver can be in isolation mode.

[0083] It should be noted that Figure 4 The internal path of the transceiver shown in is only one example. In the actual implementation process, there may be more other paths, which are not specifically limited here. When different transmission paths are selected, the corresponding isolation degree can be determined according to the corresponding physical interval. For example, for the isolation mode, different isolation levels can be divided when different transmission paths are used. There are differences in the isolation degree corresponding to different isolation levels. One of the isolation levels can be selected according to actual needs to enter the isolation mode.

[0084] In the power detection method provided in the embodiment of the present application, the transceiver includes two output terminals, each of which corresponds to a signal transmission path, wherein the physical interval between the signal transmission paths corresponding to the two output terminals of the transceiver in the normal mode is smaller than the physical interval between the signal transmission paths corresponding to the two output terminals in the isolation mode. The mode of the transceiver can be adjusted by setting the transmission paths corresponding to the two output terminals of the transceiver, thereby further increasing the device isolation of the transceiver.

[0085] In order to more clearly explain the power detection method provided in the embodiment of the present application, the following explanation is given by taking a terminal device with two transceivers as an example:

[0086] In one embodiment, the transceiver includes: a high frequency transceiver and a medium and low frequency transceiver, the high frequency transceiver and the medium and low frequency transceiver are respectively connected to a control switch; the control switch is used to connect to the transceiver indicated by the switch signal according to the switch signal.

[0087] Among them, the high-frequency transceiver and the medium- and low-frequency transceiver can be transceivers that transmit signals at different frequencies. The signal transmission frequency of the high-frequency transceiver can be greater than the signal transmission frequency of the medium- and low-frequency transceiver. In actual application, the control switch can be connected to the high-frequency transceiver or to the medium- and low-frequency transceiver by sending a corresponding switching signal to the control switch.

[0088] For example: the first input end of the control switch is connected to the medium and low frequency transceiver, and the second input end of the control switch is connected to the high frequency transceiver. Then, the medium and low frequency transceiver can be turned on by connecting the first input end of the switch through the switch signal control switch, and the high frequency transceiver can be turned on by connecting the second input end of the switch through the switch signal control switch.

[0089] It should be noted that the switch signal can be used to instruct the control switch to be connected to one of the transceivers.

[0090] In one embodiment, before the detection circuit performs power detection on the target transceiver, the method further includes: when the transceiver indicated by the switch signal is a high-frequency transceiver, controlling the switch to be turned on with the high-frequency transceiver, and transmitting the detection signal sent by the high-frequency transceiver to the detection circuit; when the transceiver indicated by the switch signal is a medium-low frequency transceiver, controlling the switch to be turned on with the medium-low frequency transceiver, and transmitting the detection signal sent by the medium-low frequency transceiver to the detection circuit.

[0091] Optionally, when the control switch is turned on with the high frequency transceiver, the detection signal sent by the high frequency transceiver can be transmitted to the detection circuit for power detection, thereby determining the corresponding power. When the control switch is turned on with the medium and low frequency transceiver, the detection signal sent by the medium and low frequency transceiver can be transmitted to the detection circuit for power detection, thereby determining the corresponding power.

[0092] In the power detection method provided in the embodiment of the present application, when the transceiver indicated by the switch signal is a high-frequency transceiver, the control switch can be connected to the high-frequency transceiver, and the detection signal sent by the high-frequency transceiver can be transmitted to the detection circuit; when the transceiver indicated by the switch signal is a medium-low frequency transceiver, the control switch can be connected to the medium-low frequency transceiver, and the detection signal sent by the medium-low frequency transceiver can be transmitted to the detection circuit. Among them, the transceiver that needs to be power detected can be selected by the switch signal, and the corresponding transceiver can be power detected, which improves the flexibility of power detection.

[0093] In one embodiment, the detection circuit is connected to each transceiver; after the detection circuit performs power detection on the target transceiver, the method further includes: when the power detected by the detection circuit is high-frequency power, sending the detection result of the high-frequency power to the high-frequency transceiver; when the power detected by the detection circuit is medium-low frequency power, sending the detection result of the medium-low frequency power to the medium-low frequency transceiver.

[0094] It should be noted that the detection circuit may be connected to each transceiver. After the detection circuit obtains the power detection result, the detection result may be sent to the corresponding transceiver. After receiving the corresponding detection result, the transceiver may perform power adjustment.

[0095] For example, if the detected transceiver power is different from the normal transmission power of the transceiver, the transceiver can adjust the power so as to transmit the signal at the normal transmission power; if the detected transceiver power is the same as the normal transmission power of the transceiver, it can be determined that the transceiver is working normally and no power adjustment is required.

[0096] Among them, if power adjustment is required, during the power adjustment process, when the detected transceiver power is greater than the normal transmission power of the transceiver, the transmission power of the transceiver can be reduced; when the detected transceiver power is less than the normal transmission power of the transceiver, the transmission power of the transceiver can be increased.

[0097] In the power adjustment method provided in the embodiment of the present application, when the power detected by the detection circuit is high-frequency power, the detection result of the high-frequency power can be sent to the high-frequency transceiver; when the power detected by the detection circuit is medium-low frequency power, the detection result of the medium-low frequency power can be sent to the medium-low frequency transceiver. By sending the detection result of the transceiver to the corresponding transceiver, the transceiver can adjust the transmission power and improve the accuracy of the transmission power.

[0098] The following will explain the process of power detection for high frequency transceivers and the process of power detection for medium and low frequency transceivers respectively.

[0099] Figure 5 For a connection diagram of the high frequency transceiver detection provided in the embodiment of the present application, please refer to Figure 5 , Figure 5 The circuit structure shown is a situation where a high-frequency transceiver is detected, wherein the high-frequency transceiver can send a control signal to the medium and low-frequency transceivers, so that the medium and low-frequency transceivers can turn on the isolation mode to increase the isolation of the device. After the detection circuit performs power detection on the detection signal of the high-frequency transceiver, the detection result can be returned to the high-frequency transceiver, so that the high-frequency transceiver can adjust the power.

[0100] Figure 6 For a connection diagram of the low-frequency transceiver detection provided in the embodiment of the present application, please refer to Figure 6 , Figure 6 The circuit structure shown is a case of detecting a mid- and low-frequency transceiver, wherein the mid- and low-frequency transceiver can send a control signal to the high-frequency transceiver, thereby turning on the isolation mode of the high-frequency transceiver to increase the isolation of the device. After the detection circuit performs power detection on the detection signal of the mid- and low-frequency transceiver, the detection result can be returned to the mid- and low-frequency transceiver, thereby allowing the mid- and low-frequency transceiver to adjust the power.

[0101] It should be noted that Figure 5 as well as Figure 6 The power adjustment process shown is a process in which two transceivers exist. In actual implementation, there may be three or more transceivers. The following explanation is given by taking three transceivers as an example.

[0102] In one embodiment, the transceiver includes: a high frequency transceiver, an intermediate frequency transceiver and a low frequency transceiver, any two of the high frequency transceiver, the intermediate frequency transceiver and the low frequency transceiver are connected to a control switch; the control switch is used to connect to the transceiver indicated by the switch signal according to the switch signal.

[0103] Among them, the high-frequency transceiver, the intermediate-frequency transceiver and the low-frequency transceiver may be transceivers that transmit signals at different frequencies. The signal transmission frequency of the high-frequency transceiver may be greater than the signal transmission frequency of the intermediate-frequency transceiver, and the transmission frequency of the intermediate-frequency signal transceiver may be greater than the signal transmission frequency of the low-frequency transceiver. In actual application, the control switch may be connected to the high-frequency transceiver, the intermediate-frequency transceiver, or the low-frequency transceiver by sending a corresponding switching signal to the control switch.

[0104] For example: if the first input end of the control switch is connected to the intermediate frequency transceiver, and the second input end of the control switch is connected to the high frequency transceiver, the intermediate frequency transceiver can be turned on by connecting the switch signal to the first input end, and the high frequency transceiver can be turned on by connecting the switch signal to the second input end; or, if the first input end of the control switch is connected to the low frequency transceiver, and the second input end of the control switch is connected to the high frequency transceiver, the low frequency transceiver can be turned on by connecting the switch signal to the first input end, and the high frequency transceiver can be turned on by connecting the switch signal to the second input end.

[0105] It should be noted that since the control switch is a single-pole double-throw switch, the control switch has only two input terminals. Any two of the high-frequency transceiver, the intermediate-frequency transceiver and the low-frequency transceiver can be selected to be connected to the control switch. The control switch can select one of the two connected control switches to be turned on through a switching signal, thereby realizing power detection.

[0106] Optionally, if the control switch is connected to a high-frequency transceiver and an intermediate-frequency transceiver, the switch signal can be used to indicate that the control switch is turned on with the high-frequency transceiver or the intermediate-frequency transceiver; if the control switch is connected to a high-frequency transceiver and a low-frequency transceiver, the switch signal can be used to indicate that the control switch is turned on with the high-frequency transceiver or the low-frequency transceiver; if the control switch is connected to a low-frequency transceiver and an intermediate-frequency transceiver, the switch signal can be used to indicate that the control switch is turned on with the low-frequency transceiver or the intermediate-frequency transceiver.

[0107] In one embodiment, before the detection circuit performs power detection on the target transceiver, the method further includes: when the transceiver indicated by the switch signal is a high-frequency transceiver, controlling the switch to be turned on with the high-frequency transceiver, and transmitting the detection signal sent by the high-frequency transceiver to the detection circuit; when the transceiver indicated by the switch signal is an intermediate frequency transceiver, controlling the switch to be turned on with the intermediate frequency transceiver, and transmitting the detection signal sent by the intermediate frequency transceiver to the detection circuit; when the transceiver indicated by the switch signal is a low-frequency transceiver, controlling the switch to be turned on with the low-frequency transceiver, and transmitting the detection signal sent by the low-frequency transceiver to the detection circuit.

[0108] Optionally, when the control switch is turned on with the high frequency transceiver, the detection signal sent by the high frequency transceiver can be transmitted to the detection circuit for power detection, thereby determining the corresponding power. When the control switch is turned on with the intermediate frequency transceiver, the detection signal sent by the intermediate frequency transceiver can be transmitted to the detection circuit for power detection, thereby determining the corresponding power. When the control switch is turned on with the low frequency transceiver, the detection signal sent by the low frequency transceiver can be transmitted to the detection circuit for power detection, thereby determining the corresponding power.

[0109] In the power detection method provided in the embodiment of the present application, when the transceiver indicated by the switch signal is a high-frequency transceiver, the control switch and the high-frequency transceiver are turned on, and the detection signal sent by the high-frequency transceiver is transmitted to the detection circuit; when the transceiver indicated by the switch signal is an intermediate frequency transceiver, the control switch and the intermediate frequency transceiver are turned on, and the detection signal sent by the intermediate frequency transceiver is transmitted to the detection circuit; when the transceiver indicated by the switch signal is a low-frequency transceiver, the control switch and the low-frequency transceiver are turned on, and the detection signal sent by the low-frequency transceiver is transmitted to the detection circuit. Among them, the transceiver that needs to be power detected can be selected by the switch signal, and the corresponding transceiver can be subjected to power detection, which improves the flexibility of power detection.

[0110] In one embodiment, the detection circuit is connected to each transceiver; after the detection circuit performs power detection on the target transceiver, the method further includes: when the power detected by the detection circuit is high-frequency power, sending the detection result of the high-frequency power to the high-frequency transceiver; when the power detected by the detection circuit is intermediate frequency power, sending the detection result of the intermediate frequency power to the intermediate frequency transceiver; when the power detected by the detection circuit is low-frequency power, sending the detection result of the low-frequency power to the low-frequency transceiver.

[0111] It should be noted that the detection circuit may be connected to each transceiver. After the detection circuit obtains the power detection result, the detection result may be sent to the corresponding transceiver. After receiving the corresponding detection result, the transceiver may perform power adjustment.

[0112] For example, if the detected transceiver power is different from the normal transmission power of the transceiver, the transceiver can adjust the power so as to transmit the signal at the normal transmission power; if the detected transceiver power is the same as the normal transmission power of the transceiver, it can be determined that the transceiver is working normally and no power adjustment is required.

[0113] Among them, if power adjustment is required, during the power adjustment process, when the detected transceiver power is greater than the normal transmission power of the transceiver, the transmission power of the transceiver can be reduced; when the detected transceiver power is less than the normal transmission power of the transceiver, the transmission power of the transceiver can be increased.

[0114] In the power adjustment method provided in the embodiment of the present application, when the power detected by the detection circuit is high-frequency power, the detection result of the high-frequency power can be sent to the high-frequency transceiver; when the power detected by the detection circuit is medium-frequency power, the detection result of the medium-frequency power can be sent to the medium-frequency transceiver; when the power detected by the detection circuit is low-frequency power, the detection result of the low-frequency power can be sent to the low-frequency transceiver. By sending the detection result of the transceiver to the corresponding transceiver, the transceiver can adjust the transmission power and improve the accuracy of the transmission power.

[0115] The following will explain the process of power detection for high frequency transceiver, medium frequency transceiver and low frequency transceiver respectively.

[0116] Figure 7 Another connection diagram of the high frequency transceiver detection provided in the embodiment of the present application is shown in FIG. Figure 7 , Figure 7 The circuit structure shown is a case where a high-frequency transceiver is detected, wherein when the high-frequency transceiver is connected to the control switch, one of the intermediate frequency transceiver or the low frequency transceiver can also be connected to the control switch, and a control signal can be sent to the intermediate frequency transceiver or the low frequency transceiver, so that the intermediate frequency transceiver or the low frequency transceiver turns on the isolation mode to increase the isolation of the device. After the detection circuit performs power detection on the detection signal of the high-frequency transceiver, the detection result can be returned to the high-frequency transceiver, so that the high-frequency transceiver can adjust the power.

[0117] The intermediate frequency transceiver may be connected to the control switch by using the transmission channel of the low frequency transceiver in a cascade manner.

[0118] Figure 8 For a connection diagram of the intermediate frequency transceiver detection provided in the embodiment of the present application, please refer to Figure 8 , Figure 8 The circuit structure shown is a case where an intermediate frequency transceiver is detected, wherein when the intermediate frequency transceiver is connected to the control switch, one of the low frequency transceiver or the high frequency transceiver can also be connected to the control switch, and a control signal can be sent to the low frequency transceiver or the high frequency transceiver, so that the low frequency transceiver or the intermediate frequency transceiver turns on the isolation mode to increase the isolation of the device. After the detection circuit performs power detection on the detection signal of the intermediate frequency transceiver, the detection result can be returned to the intermediate frequency transceiver, so that the intermediate frequency transceiver can adjust the power.

[0119] If the control switch is connected to the intermediate frequency transceiver and the high frequency transceiver, the intermediate frequency transceiver can be connected to the control switch by using the transmission channel of the low frequency transceiver in a cascade manner. If the control switch is connected to the intermediate frequency transceiver and the low frequency transceiver, the intermediate frequency transceiver can be connected to the control switch by using the transmission channel of the high frequency transceiver in a cascade manner.

[0120] Fig. 9 For a connection diagram of the low-frequency transceiver detection provided in the embodiment of the present application, please refer to Fig. 9 , Fig. 9 The circuit structure shown is a case where a low-frequency transceiver is detected, wherein when the low-frequency transceiver is connected to the control switch, one of the intermediate-frequency transceiver or the high-frequency transceiver can also be connected to the control switch, and a control signal can be sent to the intermediate-frequency transceiver or the high-frequency transceiver, so that the intermediate-frequency transceiver or the high-frequency transceiver turns on the isolation mode to increase the isolation of the device. After the detection circuit performs power detection on the detection signal of the low-frequency transceiver, the detection result can be returned to the low-frequency transceiver, so that the low-frequency transceiver can adjust the power.

[0121] The intermediate frequency transceiver may be connected to the control switch by using the transmission channel of the high frequency transceiver in a cascade manner.

[0122] It should be noted that, it has been explained above that the isolation level can be set for the isolation mode to meet different isolation requirements. The following is an explanation of the case where two different isolation levels, a high isolation mode and a low isolation mode, are set.

[0123] In one embodiment, the isolation mode includes: a high isolation mode and a low isolation mode; in the low isolation mode, the physical interval between the signal transmission paths corresponding to the two output ends of the transceiver is smaller than the physical interval between the signal transmission paths corresponding to the two output ends in the high isolation mode.

[0124] It should be noted that, please combine the above Figure 4 ,like Figure 4 If there are four or more transmission paths, then if the distance between the two transmission paths used by the output end is the farthest, for example, separated by two other transmission paths, it can be determined that it is in high isolation mode; if the distance between the two transmission paths used by the output end is shortened, for example, separated by one other transmission path, it can be determined that it is in low isolation mode.

[0125] In one embodiment, a target transceiver among at least two transceivers sends a control signal to another transceiver, including: the target transceiver sends a first control signal to turn on a low isolation mode to another transceiver; when a power detection result obtained by the target transceiver does not meet a preset threshold, the target transceiver sends a second control signal to turn on a high isolation mode to another transceiver.

[0126] It should be noted that when the isolation mode is turned on, the low isolation mode can be turned on first. If the power detection result obtained by the target transceiver does not meet the preset threshold when the low isolation mode is turned on, it can be determined that the low isolation mode does not meet the requirements, and the high isolation mode can be turned on.

[0127] The first control signal is used to control another transceiver to start a low isolation mode, and the second control signal is used to control another transceiver to start a high isolation mode.

[0128] For different transceivers, you can choose to enable high isolation mode or low isolation mode according to actual needs, so as to meet the actual use needs of different transceivers.

[0129] In the power detection method provided in the embodiment of the present application, the target transceiver can send a first control signal to another transceiver to start a low isolation mode; when the power detection result obtained by the target transceiver does not meet the preset threshold, the target transceiver sends a second control signal to another transceiver to start a high isolation mode. Among them, the low isolation mode can be used preferentially to increase the isolation degree. When the low isolation mode does not meet the use requirements, the high isolation mode can be turned on to increase the isolation degree, thereby improving the flexibility of the transceiver in improving the isolation degree.

[0130] The following is an explanation of one implementation process of power detection for a terminal device provided in an embodiment of the present application.

[0132] S1010: The target transceiver adjusts its own signal transmission power.

[0133] S1020: Connect the control switch to the target transceiver through a switch signal.

[0134] S1030: The target transceiver sends a control signal to another transceiver, and the other transceiver turns on the isolation mode.

[0135] S1040: The detection circuit performs power detection on the target transceiver and feeds back the detection result to the target transceiver.

[0136] S1050: Determine whether the detection result is equal to the theoretical value of the transmission power. If so, end the adjustment; if not, continue to execute the above step S1010.

[0137] It should be noted that a theoretical value of transmit power can be set for each target transceiver, for example: Figure 3 The theoretical value of the transmission power of the B1 transceiver can be 10dbm, and the theoretical value of the transmission power of the N78 transceiver can be 20dbm.

[0138] If the detection result is greater than the theoretical value of the transmit power, the transmit power of the transceiver can be reduced; if the detection result is less than the theoretical value of the transmit power, the transmit power of the transceiver can be increased until the two are equal.

[0139] It should be understood that, although the steps in the above-mentioned flowcharts are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders. Moreover, at least a part of the steps in the above-mentioned flowcharts may include multiple sub-steps or multiple stages, and these sub-steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these sub-steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the sub-steps or stages of other steps.
