Embodiment
In order to solve the problem not considering the factor affecting antenna performance in prior art, the invention provides a kind of aerial matching method, device and terminal.
The present invention is according to the distance of the terminal temperature collected and/or terminal antenna and human body, adjustment antenna-matching circuit (antenna matching network), as, capacitance in adjustment antenna-matching circuit and/or inductance value, and then realize Antenna Impedance Matching, reduce power loss and standing-wave ratio, reduce impact antenna caused by terminal temperature, human body distance, improve the service behaviour of antenna, enable antenna obtain maximum transmission power and received power.
Below in conjunction with accompanying drawing and embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, do not limit the present invention.
As shown in Figure 1, Fig. 1 is the flow chart of aerial matching method according to an embodiment of the invention.
Step S110, gathers the physical parameter affecting Antenna Impedance Matching.
Physical parameter comprises the distance of terminal temperature and/or terminal antenna and human body.Wherein, the distance of terminal antenna and human body is: the vertical range of antenna and human body.
The temperature of acquisition terminal is carried out, the distance of range sensor acquisition terminal antenna and human body by temperature sensor.
Step S120, according to the physical parameter collected, obtains regulating parameter.
Regulating parameter comprises capacitance and/or inductance value, is applied in antenna-matching circuit by this capacitance and/or inductance value, can realize impedance matching, makes antenna power reach optimum.
Specifically, room is measured or emulation by experiment, obtains adjustment parameter list.This regulating parameter token is loaded with and different temperature values and/or regulating parameter corresponding to distance value.By inquiring about the regulating parameter table pre-set, the regulating parameter corresponding with the temperature of current collection and/or distance can be obtained.
If only acquisition terminal temperature, then pre-set the mapping table (regulating parameter table) of temperature and regulating parameter.By inquiring about this mapping table, the regulating parameter that the temperature that acquisition collects is corresponding.
If the only distance of acquisition terminal antenna and human body, then pre-set the mapping table of distance and regulating parameter.By inquiring about this mapping table, obtain the regulating parameter that the distance of collection is corresponding.Further, regulating parameter corresponding to distance threshold value is set in regulating parameter table.This distance threshold value is for weighing the impact of human body on antenna match.The value that this distance threshold value is empirical value or obtains according to pre-defined algorithm.If the distance collected is less than or equal to this distance threshold value, then by this mapping table of normal queries, obtain the regulating parameter corresponding to distance collected.If the distance collected is greater than this distance threshold value, then by regulating parameter corresponding for distance threshold value, the regulating parameter that the distance as this collection is corresponding.
If both acquisition terminal temperature, the again distance of acquisition terminal antenna and human body, then pre-set the mapping table of temperature, Distance geometry regulating parameter.Further, if the distance collected is less than or equal to default distance threshold value, then both considered the impact of temperature on antenna match, considered again that distance was on the impact of antenna match.If the distance collected is greater than default distance threshold value, then ignore the impact of distance on antenna match, only consider that temperature is on the impact of antenna match.
With the mapping table of set temperature value, distance value and regulating parameter, pre-set temperature sampling interval and distance samples interval; According to temperature sampling interval and distance samples interval, obtain multiple temperature sampling value and multiple distance sample; For the combination of each temperature sampling value and distance sample, room is measured by experiment, obtain optimal capacitance value and/or inductance value, this optimal capacitance value and/or inductance value can make antenna obtain best transmit power and received power, using this optimal capacitance value and/or inductance value as regulating parameter.
This regulating parameter table is such as shown in table 1.Table 1 comprises the corresponding relation of temperature sampling value T, distance sample D and regulating parameter.Regulating parameter comprises capacitance C, inductance value L.Terminal temperature sampled value T chooses the scope of-40 DEG C ~ 50 DEG C, and temperature sampling is spaced apart 10 DEG C, and the distance sample D of terminal antenna and human body chooses the scope of 0cm ~ 50cm, and distance samples is spaced apart 10cm.Distance threshold value is 60cm.So after table 1 middle distance D is greater than 60cm, only consider the impact of temperature.
Table 1
Because the temperature sampling value T in regulating parameter table and distance sample D is not continuous print numerical value, so, there is the situation that the temperature that gathered by transducer and/or distance values not have record in regulating parameter table, such as: in table 1, do not comprise temperature 15 DEG C, regulating parameter that distance 15cm is corresponding.So, obtain the regulating parameter corresponding with the temperature gathered and/or distance, specifically comprise: based on the training of regulating parameter table, obtain transfer algorithm.Further, build training set based on regulating parameter table, as: the mode of room measurement or emulation by experiment, the adjustment parameter that the temperature that acquisition is between two sampled values (temperature sampling value and/or distance sample) and/or distance should be corresponding.Train based on training set, obtain transfer algorithm; The regulating parameter corresponding with the temperature gathered and/or distance is obtained according to transfer algorithm.In other words, by this transfer algorithm, can in the temperature range of adjusted parameter list and in distance range, the temperature at discontinuous place and/or regulating parameter corresponding to distance.
Such as: after collecting temperature t and distance d, in the temperature range that temperature t and distance d is in regulating parameter table and distance range, and temperature t is in two temperature sampling value [T
n, T
n+1] between, n>=1, distance d is in two distance sample [D
