Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
Embodiment one
The antenna detection method of the embodiment of the present invention can be applied to mobile terminal, mobile terminal specifically can be mobile phone,
Computer, electronic reader etc., the present invention is not especially limit this.
Referring to Fig. 2, the circuit connection diagram of the multiple antennas mobile terminal of the embodiment of the present invention is shown.
The mobile terminal include: mutiple antennas mould group and be set to transmitting-receiving access in directional coupler 40.
In concrete application, since there is the factor of various interfering mobile terminal antenna receiving and transmitting signals, examples in varying environment
Such as, by the hand of user encounter can interference signal transmitting-receiving, jolt or closed environmental signal may be limited or be disturbed, antenna
Damage etc., therefore, the embodiment of the present invention are provided with mutiple antennas mould group to mobile terminal.Wherein, mutiple antennas mould group can be set
For N number of antenna modules, N is at least positive integer 3.
In concrete application, directional coupler is set in transmitting-receiving access, can detecte the standing-wave ratio of the antenna modules.Due to
Voltage and current on transmission line is linked together by specific ratio, the characteristic impedance which is just known as
(ZO).If signal source is added in impedance magnitude and is characterized in the load of impedance, all available powers are applied to the load
On.Any mismatch on transmission line can make load impedance change, so as to cause the reflected current and voltage on transmission line, by
This produces standing wave.Constructive interference and destructive interference occur for incidence wave and back wave, lead to occur on transmission line signal voltage most
Big value (Vmax) and signal voltage minimum value (Vmin).Therefore, standing-wave ratio (VSWR) can be obtained by following equation 1 and formula 2
?；
VSWR=Vmax/Vmin (formula 1)
Wherein, Vmax indicates signal voltage maximum value；Vmin signal voltage minimum value.
VSWR=(1+ Γ)/(1- Γ) (formula 2)
Wherein, Γ is proximate to the voltage reflection coefficient of load end, is determined by load impedance (ZL) and source impedance (Zo), and Γ=
(ZL-Zo)/(ZL+Zo)。
Formula 2 can be converted by formula 1 and be obtained:
VSWR=Vmax/Vmin=(VP+VR)/(VP-VR)=(1+ (VP/VR))/(1-(VP/VR))=(1+ Γ)/(1- Γ)
Wherein, VPIndicate incident wave voltage；VRIndicate reflected wave voltage.
VSWR (voltage standing wave ratio, also referred to as vertical standing-wave ratio) passes through power source, transmission line, most for measuring wireless signal
Enter effective transimission power of load eventually.For an idealized system, transmitting energy is 100%, need source impedance, transmission line and
It is accurately matched between the characteristic impedances of other connectors, load impedance.Since interference is not present in ideal transmission process, signal
Alternating voltage keeps identical at both ends.In practice, it is reflected (such as since impedance mismatching will will lead to Partial Power to signal source direction
The same echo).Reflection causes destructive interference, generates voltage wave crest, trough in different time, distance along transmission line.Standing wave
Than that can also refer to the ratio between standing wave antinode voltage and peak voltage amplitude, as standing-wave ratio VSWR=1:1, Γ=0, indicate feeder line and
The impedance of antenna exactly matches, and high-frequency energy is all gone out by aerial radiation, not the reflection loss of energy；Standing-wave ratio is infinite
When big, energy total reflection is indicated, energy is absolutely not radiate.To sum up, standing-wave ratio is smaller, and the reflection loss of antenna is got over
Small, the reception signal of antenna is better, it is thereby possible to select the main collection antenna of the conduct of the smallest antenna of standing-wave ratio.
In concrete application, reflected wave voltage and incident wave voltage are needed due to calculating standing-wave ratio, by directional coupler
Setting is in transmitting-receiving access.Directional coupler can be used for the isolation, separation and mixing of signal, monitoring, source output work such as power
Rate fixed ampllitude, signal source isolation, transmission and reflection sweep check etc., the key technical indexes is directional, standing-wave ratio, coupling
Degree, insertion loss.In the present embodiment, directional coupler can detecte incident power in transmitting-receiving access on transmission line and anti-
Ejected wave power, according to power=voltage * electric current, the current value of transmission line is given value in mobile terminal, therefore, by orienting coupling
The incident power and the available reflected wave voltage of reflected wave powers of clutch detection and incident wave voltage, to obtain standing wave
Than.

The register value of line mould group is incorrect, it is determined that the damage of target antenna mould group.Therefore, mobile end of the present invention for multiple antennas
The method at end, detection antenna damage is simple, avoids constantly switching and attempts the antenna that has damaged, improve the performance of system with
Stability has saved system resource.
Embodiment two
The embodiment of the present invention can be applied to mobile terminal, and mobile terminal further includes multiple receiving paths, in a target day
In the case that line mould group is connected to transmitting-receiving access, remaining target antenna Mo Zu is connect with a receiving path respectively.
Referring to Fig. 4, a kind of flow chart of antenna detection method of the embodiment of the present invention two is shown.Can specifically include with
Lower step:
Step 201: the standing-wave ratio of each target antenna mould group is obtained during switching antenna；Target antenna mould group is normal
Antenna modules.
Step 202: in the case where the standing-wave ratio of a target antenna mould group is greater than given threshold, if it is determined that antenna modules
Register value it is correct, then obtain the first of target antenna mould group based on transmitting-receiving access and receive level, and based on it is each receive it is logical
The target second that road obtains remaining target antenna mould group receives level.
In concrete application, in the case where the standing-wave ratio of a target antenna mould group is greater than given threshold A, if the first register
Value is identical as the second register value, i.e., is in working condition the register value phase with target antenna mould group when working condition in antenna
Together, it is determined that the register value of the target antenna mould group is correct, can determine that the target antenna mould group is not damaged, it is also necessary into one
Step detects the stability that the target antenna mould group receives signal, if will receive electromagnetic wave in current environment or other interference because
The influence of element, leads to the reception signal limitation of the target antenna mould group, influences the normal work of mobile terminal, therefore, it is also desirable to
It obtains first of target antenna mould group in transmitting-receiving access and receives level, and obtain remaining target antenna mould group in each receiving path
Target second receive level, further judge whether the target antenna mould group can make the reception signal limitation of mobile terminal.
Step 203: receiving level, the reception level of target second based on first, it is pre- to determine whether the first reception level meets
If condition.
In concrete application, the first of target antenna mould group receives level in acquisition transmitting-receiving access, and obtains each receive and lead to
The target second of remaining target antenna mould group receives level in road, determines whether the first reception level meets preset condition.
Optionally, above-mentioned steps 203 may include following sub-step:
Step 2031: obtaining the level mean value that each target second receives level.
In concrete application, since the signal that external environment can receive each target antenna mould group brings interference, in order to obtain
The target second of remaining target antenna mould group receives the accurate numerical value of level in each receiving path, can be according to preset interval
Time is repeatedly obtained, and the average value that each target second after repeatedly obtaining receives level is then calculated.
Step 2032: judging whether the difference between the first reception level and level mean value is greater than level threshold；If poor
Value is not more than level threshold, then the first reception level does not meet preset condition；
In concrete application, the difference between the first reception level and level mean value is compared with level threshold B, level
Threshold value B can be preset value, for different types of mobile terminal, when being placed in varying environment, and the mobile terminal antenna
Reception level power it is different, corresponding receptions signal strength or weakness is also just different, and therefore, the present embodiment can be in advance to mobile whole
The reception level range that end antenna meets when working normally is tested, by the smallest reception level in institute's test level range
Value is set as level threshold B.If the first difference for receiving between level and level mean value is not more than B, the first reception level is not inconsistent
Close preset condition.
Or, step 2033: being received in level from each target second, determine that frequency of occurrence is at most that target second receives electricity
It is flat；
In concrete application, since the signal that external environment can receive each target antenna mould group brings interference, in order to obtain
The second of remaining target antenna mould group receives the accurate numerical value of level in each receiving path, can be according to preset interval time
It is repeatedly obtained, the most conduct target second of frequency of occurrence is received into level.
Step 2034: whether the difference for judging that the first reception level and target second receive between level is greater than level threshold
Value；If difference is not more than level threshold, the first reception level does not meet preset condition.
In concrete application, level is received by first and target second receives the difference between level and carries out with level threshold B
Compare, if the first level and target second receive the difference between level and be not more than B, the first reception level does not meet default item
Part.
Step 204: if the first reception level does not meet preset condition, the standing-wave ratio of target antenna mould group is obtained again,
If the standing-wave ratio of target antenna mould group is greater than given threshold, it is determined that the damage of target antenna mould group.
In concrete application, if the first difference received between level and level mean value is not more than B, or, the first level and mesh
Mark second receives the difference between level and is not more than B, at this point it is possible to determine that the target antenna mould group is due to receiving extraneous ring
The influence of interference signal in border makes the signal strength of the reception level (the first reception level) of the target antenna mould group be lower, is
Further determine that whether energy that in the target antenna mould group aerial radiation is gone out can be used for the transmitting of signal, therefore, also
It needs to detect by standing-wave ratio of the directional coupler to the antenna modules, if the standing-wave ratio of detection is still greater than given threshold
A can then determine that the efficiency of antenna reception signal is very low, be not enough to complete the transmitting of signal, will affect mobile terminal just
Often work, therefore, which is abandoned, at this moment, N number of antenna modules are downgraded to N-1 antenna modules, subsequent
In antenna handoff procedure, no longer transmitting-receiving access is connected to the target antenna mould group, directional coupler also would not be to the target
The standing-wave ratio of antenna modules is detected, and is constantly detected so as to avoid to the antenna damaged, saves system resource.
To sum up, in above-mentioned antenna detection method, when some antenna modules is confirmed as damage or in process of self-test
When middle, if N number of antenna modules are downgraded to (N-1) a antenna modules, the antenna detection method still can be used, a day (N-1)
Line mould group is downgraded to (N-2) a antenna modules, and so on, until being downgraded to 3 antenna modules.
For example, it is assumed that a certain mobile terminal includes three antenna modules, three antenna modules under default conditions are ok
It works normally, antenna selects the smallest antenna of standing-wave ratio as main collection antenna when switching.If in antenna handoff procedure, discovery
After the standing-wave ratio of a certain branch antenna is greater than A, three antenna modules are downgraded to two antenna modules, then in the mistake of subsequent switching antenna
It is no longer attempt in journey using above-mentioned antenna as main collection antenna, later, switching method can be used the switching of two antennas in Fig. 1 and calculate
Method does not use the handoff algorithms of above-mentioned mutiple antennas, to save system resource.
