It is also to be understood that the terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification of the present application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
The first embodiment is as follows:
fig. 1 shows a flowchart of a first antenna tuning method provided in an embodiment of the present application, which is detailed as follows:
step S11, acquiring an environment signal of a mobile terminal, wherein the mobile terminal is preset with a tunable capacitor and a tunable switch, and the tunable capacitor is connected with the tunable switch;
the mobile terminal of this embodiment refers to a built-in antenna, and is a terminal with a network communication function, such as a mobile phone and a tablet computer.
The tunable capacitor of this embodiment is an adjustable capacitor with an adjustable capacitance value, and specifically, an adjustable capacitor with an adjustable capacitance value may be selected, or an adjustable driving voltage is set at the mobile terminal, and the adjustable driving voltage is connected to the capacitor, so as to achieve the purpose of changing the capacitance value by adjusting the voltage of the driving voltage.
The tunable switch of the present embodiment means that the on/off of the switch is adjustable.
In this embodiment, the connection manner of the tunable capacitor and the tunable switch includes series connection and/or parallel connection. The term "and/or" as used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.
Step S12, if the environment signal of the mobile terminal meets the requirement, predicting the scene of the mobile terminal;
the scenario of the present embodiment includes any one of the following: the scenes of the horizontal screen, the vertical screen, the close-fitting placement, etc. can also include other scenes which are not listed, and are not described again here.
Of course, if the environmental signal of the mobile terminal does not meet the requirement, the scene where the mobile terminal is located is not predicted.
Step S13, if the parameters of the tunable capacitor and the parameters of the tunable switch corresponding to the scene where the mobile terminal is located are prestored, importing the parameters of the tunable capacitor and the parameters of the tunable switch, and correspondingly tuning the tunable capacitor and the tunable switch according to the imported parameters;
in this embodiment, if it is determined that the mobile terminal stores the parameter of the tunable capacitor and the parameter of the tunable switch corresponding to the predicted scene, the parameter of the tunable capacitor and the parameter of the tunable switch are imported, and the corresponding tunable capacitor and the tunable switch are adjusted according to the imported parameters, for example, if the parameter corresponding to the tunable switch 1 in the imported parameters is "off", the state of the tunable switch 1 is set to "off", and if the parameter corresponding to the tunable capacitor 1 in the imported parameters is 2 farads (F), the capacitance value of the tunable capacitor 1 is modified to 2F.
Optionally, since the pre-stored parameters of the tunable capacitor and the tunable switch are not optimal for the current predicted scenario, in order to obtain the optimal performance of the antenna, after the tuning the tunable capacitor and the tunable switch according to the imported parameters, the tuning method includes:
and continuing tuning the tunable capacitor and the tunable switch, and recording the performance of the antenna after the antenna is tuned, wherein the performance of the antenna meets the corresponding parameters of the tunable capacitor and the tunable switch.
In this embodiment, after the corresponding tunable capacitor and the tunable switch are adjusted according to the imported parameters, the tunable capacitor and the tunable switch are tuned on the basis, if the antenna performance obtained after the re-tuning meets the requirement, the parameters corresponding to the tunable capacitor and the tunable switch when the antenna performance meets the requirement are recorded, and the recorded parameters are used as the parameters of the tunable capacitor and the parameters of the tunable switch corresponding to the currently predicted scene. The tunable capacitor and the tunable switch are tuned on the previous basis, so that the adjustment speed can be improved, and the performance of the antenna in the current scene can be further improved because the new parameter of the tunable capacitor tunable switch meeting the performance requirement of the antenna is obtained on the previous basis.
Step S14, if the parameter of the tunable capacitor and the parameter of the tunable switch corresponding to the scene where the mobile terminal is located are not prestored, tuning the tunable capacitor and the tunable switch, and recording the parameter of the tunable capacitor and the parameter of the tunable switch corresponding to the requirement that the performance of the antenna after the antenna is tuned.
In this embodiment, if it is determined that the mobile terminal does not store the parameter of the tunable capacitor and the parameter of the tunable switch corresponding to the predicted scene, the recorded parameter of the tunable capacitor and the recorded parameter of the tunable switch that satisfy the performance requirement of the antenna are used as the parameter corresponding to the predicted scene.
In the embodiment of the invention, an environment signal of a mobile terminal is obtained, the mobile terminal is preset with a tunable capacitor and a tunable switch, the tunable capacitor is connected with the tunable switch, if the environment signal of the mobile terminal meets requirements, a scene where the mobile terminal is located is predicted, if a parameter of the tunable capacitor and a parameter of the tunable switch corresponding to the scene where the mobile terminal is located are prestored, the parameter of the tunable capacitor and the parameter of the tunable switch are imported, the tunable capacitor and the tunable switch are tuned correspondingly according to the imported parameters, if the parameter of the tunable capacitor and the parameter of the tunable switch corresponding to the scene where the mobile terminal is located are not prestored, the tunable capacitor and the tunable switch are tuned, and after antenna tuning is recorded, the performance of the antenna meets the requirements of the parameters of the tunable capacitor and the parameters of the tunable switch. Due to the fact that the scenes can be automatically predicted, the tunable capacitor and the tunable switch are tuned according to the predicted scenes, and the parameters of the tunable capacitor and the parameters of the tunable switch which meet the performance requirements of the antenna are obtained, the performance of the antenna can be guaranteed to meet the requirements under different scenes, the operation is more flexible, and the testing workload of the antenna in the early stage of design is reduced.
Example two:
fig. 2 shows a flowchart of a second antenna tuning method provided in the second embodiment of the present application, wherein steps S23 and S24 are the same as steps S13 and S14 of the first embodiment, and are not repeated here: in addition, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not intended to indicate or imply relative importance.
Step S21, obtaining the antenna transmitting power and the antenna receiving signal level of the mobile terminal;
in this embodiment, since the antenna transmission power and the antenna reception signal level represent the antenna performance of the mobile terminal, the environment signal of the mobile terminal selects the antenna transmission power and the antenna reception signal level.
Step S22, if the antenna transmission power of the mobile terminal is greater than or equal to a first threshold, and/or if the antenna received signal level is less than or equal to a second threshold, predicting a scene where the mobile terminal is located.
In this embodiment, if the antenna transmission power of the mobile terminal is greater than or equal to a first threshold, it is determined that the environmental signal of the mobile terminal meets the requirement; or if the level of the signal received by the antenna is less than or equal to a second threshold value, judging that the environment signal of the mobile terminal meets the requirement; or, if the antenna transmitting power of the mobile terminal is greater than or equal to a first threshold and the antenna receiving signal level is less than or equal to a second threshold, determining that the environmental signal of the mobile terminal meets the requirement. And when the environment signal meets the requirement, predicting the scene of the mobile terminal. Preferably, since predicting the scene and performing the subsequent operation consume resources of the mobile terminal, in order to save freedom of the mobile terminal, the scene where the mobile terminal is located is predicted only when the antenna transmission power of the mobile terminal is greater than or equal to the first threshold and the antenna received signal level is less than or equal to the second threshold.
Step S23, if the parameters of the tunable capacitor and the parameters of the tunable switch corresponding to the scene where the mobile terminal is located are prestored, importing the parameters of the tunable capacitor and the parameters of the tunable switch, and correspondingly tuning the tunable capacitor and the tunable switch according to the imported parameters;
of course, in this embodiment, the correspondingly tuning the tunable capacitor and the tunable switch according to the introduced input may further include: and continuing tuning the tunable capacitor and the tunable switch, and recording the performance of the antenna after the antenna is tuned, wherein the performance of the antenna meets the corresponding parameters of the tunable capacitor and the tunable switch.
Step S24, if the parameter of the tunable capacitor and the parameter of the tunable switch corresponding to the scene where the mobile terminal is located are not prestored, tuning the tunable capacitor and the tunable switch, and recording the parameter of the tunable capacitor and the parameter of the tunable switch corresponding to the requirement that the performance of the antenna after the antenna is tuned.
Optionally, the predicting the scene where the mobile terminal is located in step S12 or step S22 specifically includes:
a1, acquiring sensor parameters of at least one of the following sensors arranged on the mobile terminal: a gravity sensor, a geomagnetic sensor, an acceleration sensor and an optical sensor;
and A2, predicting the scene of the mobile terminal according to the acquired sensor parameters.
In the above-mentioned a1 and a2, different sensor parameters are used to distinguish different scenes where the mobile terminal is located, and when the sensors are different or the sensor parameters are different, the corresponding scenes are also different. For example, assuming that the sensors arranged on the mobile terminal include a gravity sensor and a geomagnetic sensor, if the acquired sensor parameter of the gravity sensor is m1 and the geomagnetic sensor is n1, the scene where the mobile terminal is located is predicted to be z 1; if the acquired sensor parameter of the gravity sensor is m2 and the geomagnetic sensor is n2, the scene where the mobile terminal is located is predicted to be z 2. Because the mobile terminal is provided with different sensors, the cost of the mobile terminal cannot be increased by predicting the scene where the mobile terminal is located by acquiring the set parameters of the sensors, and in addition, when the mobile terminal is in different scenes, the corresponding sensor parameters are different inevitably, for example, when the mobile terminal is in a horizontal screen and a vertical screen, the corresponding sensor parameters (such as gravity sensor parameters) are different.
Optionally, in order to improve the accuracy of the predicted scene, the step a2 includes:
a21, acquiring the type of the application currently started by the mobile terminal;
and A22, predicting the scene of the mobile terminal according to the type of the currently started application and the acquired sensor parameters.
In the above-mentioned a21 and a22, the type of the application currently started by the mobile terminal (for example, the application started by the foreground of the mobile terminal) and the acquired sensor parameter are combined to predict the scene where the mobile terminal is located. It should be noted that, if the mobile terminal does not have the application started currently, it indicates that the mobile terminal is currently in a state of not being used, and at this time, the performance of the antenna does not greatly affect the user, and at this time, the operation of scene prediction may not be performed.
Optionally, the performance of the antenna may be embodied by gain, input impedance, standing-wave ratio, and the like, in this embodiment, the performance of the antenna is embodied by antenna transmission power and antenna received signal level, and specifically, whether the performance of the antenna meets the requirement is determined by the following method:
b1, acquiring the minimum antenna transmitting power and the strongest antenna receiving signal level corresponding to the normal communication of the mobile terminal, and judging whether the minimum antenna transmitting power is smaller than the antenna transmitting power corresponding to the mobile terminal before antenna tuning and/or judging whether the strongest antenna receiving signal level is larger than the antenna receiving signal level corresponding to the mobile terminal before antenna tuning;
specifically, if the antenna transmission power of the mobile terminal is greater than or equal to the first threshold, it is determined that the environmental signal of the mobile terminal meets the requirement, and then it is determined in step B1 whether the minimum antenna transmission power is less than the corresponding antenna transmission power before antenna tuning; if the antenna received signal level is less than or equal to the second threshold, determining that the environmental signal of the mobile terminal meets the requirement, then in step B1, determining whether the strongest antenna received signal level is greater than the corresponding antenna received signal level before antenna tuning; if the antenna transmission power of the mobile terminal is greater than or equal to the first threshold and the antenna received signal level is less than or equal to the second threshold, it is determined that the environmental signal of the mobile terminal meets the requirement, then in step B1, it is determined whether the minimum antenna transmission power is less than the antenna transmission power corresponding to the antenna before the antenna tuning, and it is determined whether the strongest antenna received signal level is greater than the antenna received signal level corresponding to the antenna before the antenna tuning.
B2, if the minimum antenna transmitting power is smaller than the corresponding antenna transmitting power before the antenna tuning, and/or if the strongest antenna receiving signal level is larger than the corresponding antenna receiving signal level before the antenna tuning, judging that the performance of the antenna meets the requirement, otherwise, judging that the performance of the antenna does not meet the requirement.
Optionally, in order to be able to accurately adjust the performance of the antenna, the number of the tunable capacitors may be set to be greater than or equal to 1, and the number of the tunable switches may be greater than or equal to 1;
correspondingly, the tuning the tunable capacitance and the tunable switch specifically includes:
and tuning the tunable capacitor and the tunable switch by changing the connection relationship between the tunable capacitor and the tunable switch.
In this embodiment, a tunable switch may be set to correspond to a tunable capacitor according to the wiring positions of the tunable capacitor and the tunable switch, and at this time, when the tunable switch is in an off state, the tunable switch is communicated with the tunable capacitor. A tunable switch can be set to correspond to a plurality of tunable capacitors, and if the tunable switch 1 corresponds to the tunable capacitor a, the tunable capacitor B and the tunable capacitor C, the tunable switch is communicated with the tunable capacitor a when the tunable switch 1 is in a closed state x; when the tunable switch 1 is in a closed state y, the tunable switch is communicated with a tunable capacitor B; when the tunable switch 1 is in the off-state z, the tunable switch is in communication with the tunable capacitor C.
Of course, in this embodiment, one tunable capacitor may be further disposed to correspond to the plurality of tunable switches, which is not described herein again.
