The embodiment of the application discloses an antenna detection method and device, electronic equipment and a storage medium, which can enable the electronic equipment to accurately configure a transmitting-receiving antenna with the highest current antenna performance, thereby being beneficial to improving the communication performance of the electronic equipment.
The following detailed description is made with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic view of an application scenario of an antenna detection method disclosed in the embodiment of the present application, including an electronic device 10. The electronic device 10 may include a plurality of candidate antennas 20, such as an antenna 21, an antenna 22, an antenna 23, an antenna 24, and the like. It should be noted that the positions, the directivities, the spectrum characteristics, and the like of the antennas 20 to be selected on the electronic device 10 may be different, and may be used to implement the same type of wireless communication function, or may be used to implement different types of wireless communication functions (e.g., 5G band communication, 4G band communication, Wi-Fi band communication, and the like). On this basis, fig. 1 may show only some of the candidate antennas 20 in the electronic device 10 as an example, and should not be considered as a limitation on the number and types of antennas in the embodiment of the present application.
The electronic device 10 may include various devices or systems with wireless communication functions, such as a mobile phone, a smart wearable device, an in-vehicle terminal, a tablet Computer, a PC (Personal Computer), a PDA (Personal Digital Assistant), and the like, which are not limited in this embodiment. It should be noted that the electronic device shown in fig. 1 is a mobile phone, which is merely an example and should not be considered as a limitation on the device type of the electronic device in the embodiment of the present application.
In the related art, when the electronic device 10 needs to determine the antenna performance of the antenna 20 to be selected, the determination is usually performed by receiving a downlink signal of an external network, that is, when different antennas 20 to be selected are configured according to the electronic device 10, the strengths of the downlink signals received by the antennas 20 to be selected are compared, so as to determine the antenna to be selected with the highest antenna performance. However, under the condition that the external network connected to the electronic device 10 is unstable, the downlink signal strength received by each antenna to be selected 20 may fluctuate greatly, and it is difficult to accurately reflect the actual antenna performance; moreover, in a case where the electronic device 10 cannot be connected to an external network, the above-described test method cannot be performed, so that it is difficult for the electronic device 10 to reliably determine the antenna to be selected with the highest antenna performance.
In the embodiment of the present application, in order to determine the antenna to be selected with the highest antenna performance from the antennas 20 to be selected as the transceiver antenna of the electronic device 10, the electronic device 10 may perform mutual detection by using the antennas 20 to be selected. For example, the electronic device 10 may detect the signal strength corresponding to each antenna 20 to be selected through the detection antenna corresponding to each antenna 20 to be selected, respectively, when each antenna 20 to be selected is in the signal transmission state. Taking a target candidate antenna as an example, the target candidate antenna may be any one of the multiple candidate antennas 20, and the detection antenna corresponding to the target candidate antenna may include all the other candidate antennas 20 except the target candidate antenna in the multiple candidate antennas 20. On this basis, the electronic device 10 may determine, according to the signal strength corresponding to each antenna 20 to be selected, the antenna 20 to be selected with the highest antenna performance from the multiple antennas 20 to be selected, and configure the antenna 20 to be selected with the highest antenna performance as the transceiver antenna of the electronic device 10.
As can be seen, by implementing the antenna detection method, the electronic device 10 with multiple antennas can utilize the antennas 20 to be selected as the detection antennas, so as to accurately detect the antenna 20 with the highest antenna performance. The antenna detection method can avoid the situation that the detection result is inaccurate or even cannot be detected due to the fact that the antenna performance detection method depends on an uncertain external network. Meanwhile, the advantage of mutual detection among multiple antennas can be utilized, the accuracy of the detection result is improved, the electronic device 10 can accurately configure the receiving and transmitting antenna with the highest current antenna performance, accurate and reliable antenna switching is convenient to realize, and the communication performance of the electronic device 10 is improved.
Referring to fig. 2, fig. 2 is a schematic flowchart of an antenna detection method disclosed in an embodiment of the present application, where the method may be applied to the electronic device, and the electronic device may include a plurality of antennas to be selected. As shown in fig. 2, the antenna detection method may include the steps of:
202. and respectively detecting the signal intensity corresponding to each antenna to be selected through a detection antenna corresponding to each antenna to be selected under the condition that each antenna to be selected is in a signal transmitting state, wherein the detection antenna corresponding to the target antenna to be selected comprises other antennas to be selected except the target antenna to be selected in the plurality of antennas to be selected, and the target antenna to be selected is any one antenna to be selected in the plurality of antennas to be selected.
In the embodiment of the application, the electronic device with multiple antennas may determine the antenna to be selected with the highest antenna performance as the transceiver antenna of the electronic device by detecting each antenna to be selected, so as to improve the communication performance of the electronic device as much as possible. The higher the antenna performance of the transceiving antenna of the electronic equipment is, the higher the ability of the transceiving antenna of the electronic equipment to transmit and/or receive wireless signals can be shown, so that the electronic equipment can adapt to scenes with weak signal strength and poor communication conditions, and the reliability of the electronic equipment in wireless communication is ensured.
For example, the electronic device may determine its antenna performance, such as transmission gain, reception gain, received signal strength, etc., by detecting specified antenna parameters of the antenna to be selected. In this embodiment of the application, the electronic device may sequentially use each antenna to be selected as a target antenna to be selected, and detect the signal strength corresponding to the target antenna to be selected through the corresponding detection antenna when the target antenna to be selected is in a signal transmission state, so that the antenna performance of the target antenna to be selected may be evaluated in the subsequent steps according to the value of the signal strength. The detection antenna corresponding to the target antenna to be selected may include all antennas to be selected except the target antenna to be selected in the multiple antennas to be selected. Different from a detection scheme depending on an external network in the related art, the electronic device in the embodiment of the application can complete the cyclic detection for each antenna to be selected completely and independently, that is, the whole antenna detection process can be conveniently realized through the mutual alternate detection among a plurality of antennas to be selected included in the electronic device.
Referring to fig. 3, fig. 3 is a schematic diagram of a loop detection process of an antenna detection method according to an embodiment of the present application. As shown in fig. 3, the electronic device may include N candidate antennas (N is a positive integer), and may control the target candidate antenna TXi(i ═ 1,2,3 …, N) transmits a detection signal at a certain transmission power (for example, the maximum transmission power supported by the target candidate antenna, or a specified standard test power, etc.), and at the same time, the target candidate antenna TX can be controllediCorresponding detection antenna RX1、RX2……RXN-1To receive the received signal corresponding to the detection signal and determine the corresponding received signal strength. Wherein, the detecting antenna RX1、RX2……RXN-1May include the above-mentioned N candidate antennas (TX)1、TX2……TXN) Middling target candidate antenna TXiAll other antennas to be selected. After the detection is completed for the current target candidate antenna, the electronic device may detect another target candidate antenna according to the same process againAnd detecting the N antennas to be selected until all the N antennas to be selected are detected. On this basis, the electronic device may determine, in the subsequent step, the antenna to be selected with the highest antenna performance from the N antennas to be selected, as the transceiver antenna of the electronic device, according to the received signal strength corresponding to each antenna to be selected.
204. And according to the signal intensity corresponding to each antenna to be selected, determining the antenna to be selected with the highest antenna performance from the plurality of antennas to be selected, and configuring the antenna to be selected with the highest antenna performance as a transceiving antenna of the electronic equipment.
In the embodiment of the application, after determining the signal strength corresponding to each antenna to be selected, the electronic device may perform comparative analysis based on each signal strength value, comprehensively determine the antenna performance of each antenna to be selected, and further determine the antenna to be selected with the highest antenna performance. For example, if the signal strength value corresponding to a certain antenna to be selected is larger, it may indicate that the gain of the detection signal transmitted by the antenna to be selected is relatively larger and the attenuation during transmission is relatively less, so that the antenna to be selected is more suitable for being used as the current transceiving antenna of the electronic device.
In some embodiments, the electronic device may directly perform a transverse comparison on the signal strength corresponding to each antenna to be selected, so as to determine the antenna to be selected with the largest corresponding signal strength, and configure the antenna to be selected as a transceiver antenna of the electronic device.
In other embodiments, the electronic device may also perform preprocessing, such as error correction, normalization, and the like, on the signal strength corresponding to each antenna to be selected according to a unified flow to obtain a first strength parameter corresponding to each antenna to be selected, and then the electronic device may perform comparative analysis according to each first strength parameter, thereby facilitating to improve accuracy and reliability of an antenna detection result, and simultaneously, reducing a calculation difficulty and improving an efficiency of the electronic device in determining the receiving and transmitting antennas.
In still other embodiments, since the detection antenna corresponding to each candidate antenna may include a plurality of antennas, the signal strength detected by the electronic device corresponding to each candidate antenna may also include a plurality of antennas. For the signal strengths corresponding to the target antenna to be selected, the electronic device may first calculate a second strength parameter corresponding to the target antenna to be selected, where the second strength parameter may include a sum, an average, and the like of the signal strengths, and then the electronic device may perform comparative analysis according to the second strength parameter corresponding to each antenna to be selected, so as to determine the antenna to be selected with the highest antenna performance.
Therefore, by implementing the antenna detection method described in the above embodiment, the electronic device with multiple antennas can use each antenna to be selected as a detection antenna for each other, so that the antenna to be selected with the highest antenna performance can be accurately detected. The antenna detection method can avoid the situation that the detection result is inaccurate or even cannot be detected due to the fact that the antenna performance detection method depends on an uncertain external network. Meanwhile, the advantage of mutual detection among multiple antennas can be utilized, the accuracy of the detection result is improved, the electronic equipment can accurately configure the receiving and transmitting antenna with the highest current antenna performance, and the communication performance of the electronic equipment is improved.
Referring to fig. 4, fig. 4 is a schematic flowchart illustrating another antenna detection method disclosed in the embodiment of the present application, where the method may be applied to the electronic device, and the electronic device may include a plurality of antennas to be selected. As shown in fig. 4, the antenna detection method may include the steps of:
402. and under the condition that the target antenna to be selected is in a signal transmitting state, setting a plurality of detection antennas corresponding to the target antenna to be selected as a signal receiving state, wherein the target antenna to be selected is any one antenna to be selected in the plurality of antennas to be selected.
In the embodiment of the application, the electronic device may take each antenna to be selected as a target antenna to be selected in sequence, and detect the antenna performance of the target antenna to be selected. At this time, the electronic device may use all other antennas to be selected except the target antenna to be selected as the detection antennas corresponding to the target antenna to be selected. In order to implement the detection, after the electronic device determines the target candidate antenna, the electronic device may set each corresponding detection antenna to a signal receiving state, so as to receive the detection signal transmitted by the target candidate antenna.
It can be understood that, when the electronic device sets the detection antenna corresponding to the target candidate antenna to be in the signal receiving state, the target candidate antenna may also be set to be in the signal transmitting state correspondingly, so as to transmit the detection signal to the external space. For example, the electronic device may set the target candidate antenna to a signal transmission state in response to the antenna detection instruction, so as to trigger the target candidate antenna to transmit a detection signal according to the maximum transmission power (i.e., the maximum transmission power supported by the target candidate antenna); optionally, the electronic device may also configure the target candidate antenna so that the target candidate antenna transmits the detection signal according to the specified standard test power.
In some embodiments, the electronic device may control the transceiving state of each of the antennas to be selected through a dedicated radio frequency transceiving module. For example, different ports for signal transmission and signal reception may be provided on the rf transceiver module, and the electronic device may configure the antenna to be selected through a Single Pole Double Throw (SPDT) switch or a selection circuit with similar functions. When the antenna to be selected is communicated with the signal transmitting port on the radio frequency transceiving module, the antenna to be selected can be set to be in a signal transmitting state; when the antenna to be selected is conducted with the signal receiving port on the radio frequency transceiving module, the antenna to be selected can be set to be in a signal receiving state.
In other embodiments, the electronic device may also implement the control logic through an application specific integrated circuit such as an FPGA (Field Programmable Gate Array), so that the electronic device may respond to an antenna detection instruction to quickly configure a currently selected target antenna to be selected and a corresponding detection antenna, which is beneficial to improving the efficiency and flexibility of antenna detection performed by the electronic device.
404. And respectively detecting the received signal strength corresponding to each target antenna to be selected in a signal receiving state through the detection antenna corresponding to each target antenna to be selected.
In the embodiment of the application, after the electronic device sets the detection antenna corresponding to the target antenna to be selected to be in the signal receiving state, the detection antenna can be used for receiving the wireless signal which is in accordance with the receiving frequency range of the detection antenna in the external space. For example, for a detection signal transmitted by a target candidate antenna, each detection antenna in a signal receiving state may receive a received signal corresponding to the detection signal, and then may determine the received signal strength corresponding to the target candidate antenna according to the received signal.
In some embodiments, after the electronic device sequentially takes each antenna to be selected as a target antenna to be selected and detects the received signal strength corresponding to each target antenna to be selected through each detection antenna corresponding to each target antenna to be selected, the received signal strengths may be collectively sorted and recorded in the signal strength collection table. Illustratively, the signal strength collection table may be in a format as shown in table 1 below ("\" indicates that no data is recorded here).
Table 1:
Figure BDA0003474292540000091
the antennas a1 to a4 respectively represent the antennas to be selected included in the electronic device (taking 4 antennas to be selected in total as an example), and for the case where each antenna to be selected is used as a target antenna to be selected, other 3 antennas to be selected can be set to be in a signal receiving state, so as to obtain corresponding received signal strength, and the received signal strength is applied to subsequent steps to achieve evaluation of antenna performance of each target antenna to be selected.
406. And respectively comparing the received signal strength corresponding to each antenna to be selected with corresponding calibration data, and determining the antenna to be selected with the minimum signal strength drop according to the comparison result as the antenna to be selected with the highest antenna performance, wherein the calibration data comprises the maximum measured signal strength corresponding to each antenna to be selected.
In the embodiment of the application, for the condition that each antenna to be selected is used as a target antenna to be selected, each detection antenna corresponding to the target antenna to be selected may be correspondingly provided with certain calibration data. The calibration data may be used to indicate the maximum measured signal strength corresponding to each antenna to be selected, that is, for a target antenna to be selected, the calibration data may indicate the maximum measured signal strength that can be detected by each detection antenna corresponding to the target antenna to be selected. For example, when the candidate antenna a1 is used as the target candidate antenna, the received signal strength (i.e., the maximum measured signal strength) of the received signal corresponding to the detection signal transmitted by the antenna a1, which is detected by the corresponding detection antenna a2, A3, a4, is as free of obstruction and interference as possible, i.e., can be used as the calibration data corresponding to the target candidate antenna a 1.
On the basis of this, in the actual detection process, the received signals corresponding to the detection signals transmitted by the a1 detected by the respective detection antennas a2, A3 and a4 may have different degrees of attenuation, so that the actually detected received signal strength should be less than or equal to the above calibration data. Therefore, the electronic device may compare the received signal strength corresponding to each antenna to be selected with the corresponding calibration data, and determine the antenna to be selected with the smallest signal strength drop based on the difference between the received signal strength and the corresponding calibration data. In some embodiments, if the maximum transmission power of each antenna to be selected is equal or similar, the antenna to be selected with the smallest signal strength drop is the antenna to be selected with the highest antenna performance among the antennas to be selected.
408. And if the currently configured transceiving antenna of the electronic equipment is not the antenna to be selected with the highest antenna performance, switching the currently configured transceiving antenna to the antenna to be selected with the highest antenna performance.
In the embodiment of the present application, since the environment in which the electronic device is located may change very rapidly (for example, the user holds the electronic device to move or place), the transceiver antenna currently configured in the electronic device may not be the antenna to be selected with the highest antenna performance. At this time, the electronic device may switch the transceiver antenna, that is, switch the currently configured transceiver antenna to the antenna to be selected with the highest antenna performance determined in the antenna detection process. In some embodiments, the electronic device may implement the above switching through a dedicated radio frequency transceiver module, and set the antenna to be selected with the highest antenna performance as a transceiver antenna, while other antennas to be selected may not be processed, and may shield or disable part of the transceiver function, so as to avoid causing unnecessary interference to the transceiver antenna, and improve the communication performance of the electronic device as much as possible.
It can be seen that, with the antenna detection method described in the foregoing embodiment, the electronic device with multiple antennas can utilize each antenna to be selected as a detection antenna, and further can accurately detect the antenna to be selected with the highest antenna performance, which can not only avoid the situation that the detection result is misaligned or even impossible to detect due to the dependence on an uncertain external network when detecting the antenna performance, but also improve the accuracy of the detection result by utilizing the advantage of mutual detection among the multiple antennas, so that the electronic device can accurately configure the transceiver antenna with the highest current antenna performance, thereby facilitating the improvement of the communication performance of the electronic device. In addition, the antenna performance of the antenna to be selected is judged by utilizing the calibration data measured in advance, so that the slight state change of the antenna can be effectively reflected, and the accuracy and the reliability of the antenna detection result can be further improved.
Referring to fig. 5, fig. 5 is a schematic flowchart illustrating a further antenna detection method disclosed in the embodiment of the present application, where the method can be applied to the electronic device, and the electronic device may include a plurality of antennas to be selected. The plurality of antennas to be selected may include a main set antenna and a diversity antenna, where the main set antenna may include an external main antenna and an internal main antenna, and the diversity antenna may include an external diversity antenna and an internal diversity antenna. As shown in fig. 5, the antenna detection method may include the steps of:
502. and responding to an antenna detection instruction of the electronic equipment, and setting a target antenna to be selected as a signal transmission state to trigger the target antenna to be selected to transmit a detection signal according to the maximum transmission power, wherein the target antenna to be selected is any one of the plurality of antennas to be selected.
504. And under the condition that the target antenna to be selected is in a signal transmitting state, setting a plurality of detection antennas corresponding to the target antenna to be selected as a signal receiving state.
506. And respectively receiving the receiving signals corresponding to the detection signals through the detection antennas corresponding to the target antennas to be selected in the signal receiving state, and determining the strength of the receiving signals corresponding to the target antennas to be selected according to the receiving signals.
Step 502, step 504 and step 506 have been described in the above embodiments of step 402 and step 404, and are not described herein again.
It should be noted that, in some embodiments, the electronic device may control the transceiving state of each antenna to be selected through a dedicated radio frequency transceiving module, so that corresponding settings may be performed for the target antenna to be selected and each detection antenna corresponding to the target antenna to be selected.
For example, when the electronic device sets the target candidate antenna to be in a signal transmission state, the electronic device may, in response to an antenna detection instruction of the electronic device, turn on a connection path between the target candidate antenna and the radio frequency transceiver module through the first switch circuit, so that the radio frequency transceiver module may be configured to control the target candidate antenna to perform signal transceiving. And under the condition that the target antenna to be selected is in a signal transmitting state, the electronic device can further respectively conduct the connection paths between the plurality of detection antennas corresponding to the target antenna to be selected and the radio frequency transceiver module through each second switch circuit, so that the radio frequency transceiver module can be further used for controlling each detection antenna corresponding to the target antenna to be selected to receive signals.
For example, please refer to fig. 6, fig. 6 is a schematic structural diagram of an antenna detection circuit according to an embodiment of the present disclosure. As shown in fig. 6, the antenna detection circuit may include a plurality of antennas 610 to be selected and an rf transceiver module 620. The plurality of candidate antennas 610 may include an external main antenna 611 and an internal main antenna 612, and an external diversity antenna 613 and an internal diversity antenna 614. The rf transceiver module 620 may include an rf transceiver 621, a main rf transceiver 622 and a diversity rf transceiver 623.
For example, to implement control of the main set antenna, the rf transceiver 621 may be connected to the external main antenna 611 and the internal main antenna 612 through a first main set switch circuit 631 and a second main set switch circuit 632, respectively, and the external main antenna 611 and the internal main antenna 612 may also be connected to the main set rf transceiver component 622 through a third main set switch circuit 633, respectively, so as to connect to the rf transceiver 621 through the main set rf transceiver component 622 for signal transceiving.
On this basis, when the external main antenna 611 is set as the target candidate antenna, the external main antenna 611 can be conducted to the main rf transceiver component 622 through the first main set switch circuit 631 and the third main set switch circuit 633, so as to be used for transmitting the detection signal. At this time, the built-in main antenna 612 can be directly conducted to the rf transceiver 621 through the second main set switch circuit 632, so as to receive the receiving signal corresponding to the detection signal.
When the internal main antenna 612 is set as a target candidate antenna, the internal main antenna 612 may be turned on to the main rf transceiver component 622 through the second main set switch circuit 632 and the third main set switch circuit 633, so as to be used for transmitting a detection signal. At this time, the external main antenna 611 may be directly conducted to the rf transceiver 621 through the first main set switch circuit 631, so as to receive the receiving signal corresponding to the detection signal.
Similarly, to implement the control of the diversity antenna, the rf transceiver 621 may be connected to the external diversity antenna 613 and the internal diversity antenna 614 through a first diversity switch circuit 641 and a second diversity switch circuit 642, respectively, and the external diversity antenna 613 and the internal diversity antenna 614 may also be connected to the diversity rf transceiver component 623 through a third diversity switch circuit 643, respectively, so as to connect to the rf transceiver 621 through the diversity rf transceiver component 623 for signal transceiving.
It can be understood that, no matter the external main antenna 611 or the internal main antenna 612 is used as the target candidate antenna, the external diversity antenna 613 and the internal diversity antenna 614 at this time can be used as the detection antenna corresponding to the target candidate antenna, and are directly conducted to the rf transceiver 621 for receiving the receiving signal corresponding to the target candidate antenna. Regardless of whether the external diversity antenna 613 or the internal diversity antenna 614 is used as the target candidate antenna, the external main antenna 611 and the internal main antenna 612 can also be used as the detection antennas corresponding to the target candidate antenna, and are directly conducted to the rf transceiver 621 to receive the corresponding received signal.
508. According to the signal intensity corresponding to the external main antenna and the signal intensity corresponding to the internal main antenna, determining a target main set antenna with the highest antenna performance from the external main antenna and the internal main antenna; and determining a target diversity antenna with the highest antenna performance from the external diversity antenna and the internal diversity antenna according to the signal strength corresponding to the external diversity antenna and the signal strength corresponding to the internal diversity antenna.
510. And configuring the target main set antenna and the target diversity antenna as a transceiving antenna of the electronic equipment.
Step 508 and step 510 are similar to step 204. It should be noted that, in the embodiment of the present application, the electronic device may perform mutual detection by using all 4 antennas to be selected (i.e., the external main antenna, the internal main antenna, the external diversity antenna, and the internal diversity antenna) when detecting the performance of the antenna; when configuring the transceiver antenna of the electronic device, the target main set antenna and the target diversity antenna can be configured from the 2 main set antennas and the 2 diversity antennas respectively. By respectively configuring the main set antenna and the diversity antenna of the electronic equipment, the receiving and transmitting antenna of the electronic equipment can be flexibly set, and the communication performance of the electronic equipment is improved as much as possible.
When the electronic device determines the target main set antenna and the target diversity antenna with the highest antenna performance according to the signal strength corresponding to each antenna to be selected, the electronic device may compare the signal strength corresponding to each antenna to be selected with corresponding calibration data, and determine the antenna to be selected with the smallest signal strength drop according to the comparison result, and the antenna to be selected with the highest antenna performance is used as the antenna to be selected. For example, the electronic device may determine, according to the comparison result, one of the external main antenna and the internal main antenna with the smallest signal strength drop as the target main set antenna; meanwhile, one of the external diversity antenna and the internal diversity antenna with the minimum signal strength drop can be determined as the target diversity antenna.
It can be seen that, with the antenna detection method described in the foregoing embodiment, the electronic device with multiple antennas can utilize each antenna to be selected as a detection antenna, and further can accurately detect the antenna to be selected with the highest antenna performance, which can not only avoid the situation that the detection result is misaligned or even impossible to detect due to the dependence on an uncertain external network when detecting the antenna performance, but also improve the accuracy of the detection result by utilizing the advantage of mutual detection among the multiple antennas, so that the electronic device can accurately configure the transceiver antenna with the highest current antenna performance, thereby facilitating the improvement of the communication performance of the electronic device.
