In step s 102, according to the reception result data and at least one described signal receiving device respectively with institute
The distance between charging pile is stated, determines the distance of near field range of the near-field-communication signal of the sender unit transmitting.
Wherein, the distance of near field of the near-field-communication signal of the sender unit transmitting is specially the signal transmitting dress
Set the radiation length of the near-field-communication signal of transmitting.So, the near field of the near-field-communication signal of the sender unit transmitting
Distance range is specially the radiation length range of the near-field-communication signal of the sender unit transmitting.In addition, this is apart from model
Enclosing determining step can be executed by any suitable equipment with data-handling capacity.
As an example it is assumed that the quantity of signal receiving device is three, and these three signal receiving devices and charging pile
Distance respectively 30cm, 35cm, 40cm, when the signal receiving device at a distance from charging pile being 30cm receives signal transmitting dress
It sets the near-field-communication signal of transmitting, for the signal receiving device of 35cm be not received by sender unit at a distance from charging pile
The near-field-communication signal of transmitting, the signal receiving device at a distance from charging pile for 40cm are not received by sender unit hair
When the near-field-communication signal penetrated, it may be determined that the distance of near field range of the near-field-communication signal of sender unit transmitting is
[30,35)；When the signal receiving device at a distance from charging pile being 30cm receives the near-field communication that sender unit emits
Signal, at a distance from charging pile for 35cm signal receiving device receive sender unit transmitting near-field-communication signal,
When being not received by the near-field-communication signal of sender unit transmitting with the signal receiving device at a distance from charging pile for 40cm,
The distance of near field range that can determine the near-field-communication signal of sender unit transmitting be [35,40).
In step s 103, it when determining that the distance of near field range and Target near field distance range mismatch, determines and uses
In the signal characteristic parameter of the adjusting distance of near field range, and determining signal characteristic parameter is sent to the charging pile,
So that the charging pile, which controls the sender unit according to the signal characteristic parameter of the determination, emits near-field-communication signal.
Wherein, the Target near field distance range can be set according to actual needs by those skilled in the art, this hair
Bright embodiment is not limited in any way this.The signal characteristic parameter includes the carrier frequency or carrier wave of the near-field-communication signal
Duty ratio.In a particular embodiment, when determining that the distance of near field range and Target near field distance range mismatch, really

It executes.
For example, when the distance of near field range is specially [30,35), and the Target near field distance range is specific
For [35,40) when, it may be determined that the distance of near field range and the Target near field distance range mismatch.When the distance of near field
Range be specially [35,40), and the Target near field distance range be specially [35,40) when, it may be determined that the distance of near field
Range is matched with the Target near field distance range.Specifically, when the upper and lower bound of the distance of near field range respectively with institute
When stating the upper and lower bound matching of Target near field distance range, it may be determined that the distance of near field range and the Target near field distance
Commensurate in scope.
In a particular embodiment, it is iteratively performed reception result obtaining step, distance range determines step and parameter
Set-up procedure, until determining distance of near field range is matched with the Target near field distance range.Specifically, it changes for the first time
In generation processing, the signal characteristic parameter is determined so as to the near field of the near-field-communication signal of the sender unit transmitting
Apart from farthest carrier-frequency data；In non-iterative processing for the first time, the value for the signal characteristic parameter that previous iteration determines is subtracted
Go the first predeterminated frequency step-length as the value of currently determining signal characteristic parameter.Optionally, in non-iterative processing for the first time, also
The value for the signal characteristic parameter that can determine previous iteration is plus the second predeterminated frequency step-length as currently determining signal characteristic
The value of parameter.Wherein, the first predeterminated frequency step-length is specially the carrier frequency of near-field-communication signal in gradually decrementing procedure
In difference between two adjacent carrier-frequency datas, for example, the first predeterminated frequency step-length can be 1KHz or 0.5KHz,
The second predeterminated frequency step-length be specially near-field-communication signal carrier frequency in gradually increasing process two adjacent loads
Difference between wave frequency rate data, for example, the second predeterminated frequency step-length can be 1KHz or 0.5KHz.
Here, so that the farthest number of carrier frequencies of the distance of near field of the near-field-communication signal of sender unit transmitting
According to can determine to obtain by change curve as shown in Figure 4.As shown in figure 4, abscissa indicates the opposite frequency of near-field-communication signal
Rate, ordinate indicate the relative sensitivity of near-field-communication signal.Specifically, f indicates the carrier frequency of near-field-communication signal, f0For
So that the numerical value of the farthest carrier frequency of the distance of near field of near-field-communication signal, for example, 38KHz, EeTo work as near-field-communication signal
Carrier frequency be f0When near-field-communication signal sensitivity numerical value, Ee minIndicate the sensitivity of near-field-communication signal, phase
To frequency by f/f0It is calculated, relative sensitivity is by Ee min/EeIt is calculated.As seen from the figure, when relative frequency is in 0.7 He
When between 1.0, relative sensitivity increases with the increase of relative frequency, when relative frequency is between 1.0 and 1.3, relatively
Sensitivity reduces with the increase of relative frequency.In addition, present inventor also found in the course of the study, near field is logical
The distance of near field of letter signal increases with the increase of the sensitivity of near-field-communication signal.It is can determine that as a result, when relative frequency exists
When between 0.7 and 1.0, the distance of near field of near-field-communication signal increases with the increase of relative frequency；When relative frequency is 1.0
And when between 1.3, the distance of near field of near-field-communication signal reduces with the increase of relative frequency.Further, it may be determined that: when
When relative frequency is 1.0, the distance of near field of near-field-communication signal is maximum.It is can get as a result, so that sender unit hair
The farthest carrier-frequency data of the distance of near field for the near-field-communication signal penetrated.
Under normal conditions, the setting of Target near field distance range does not exceed the farthest distance of near field.Therefore, in iteration for the first time
In processing, signal characteristic parameter is determined so that the distance of near field of the near-field-communication signal of sender unit transmitting is farthest
Then the value for the signal characteristic parameter that previous iteration determines in non-iterative processing for the first time, is subtracted first by carrier-frequency data
Value of the predeterminated frequency step-length as currently determining signal characteristic parameter, to be steadily decreasing the close of sender unit transmitting
The distance of near field of field signal of communication, so that the distance of near field range and target of the near-field-communication signal of sender unit transmitting
Distance of near field commensurate in scope.It, can also be true by previous iteration by the analysis above with respect to Fig. 4 it is found that in non-iterative processing for the first time
Value of the value of fixed signal characteristic parameter plus the second predeterminated frequency step-length as currently determining signal characteristic parameter, thus not
Reduce the distance of near field of the near-field-communication signal of sender unit transmitting disconnectedly, so that the near field of sender unit transmitting
The distance of near field range of signal of communication is matched with Target near field distance range.Wherein, the first predeterminated frequency step-length and second is preset
Frequency step can be set according to actual needs by those skilled in the art, and the embodiment of the present invention is not limited in any way this.
In addition, the first predeterminated frequency step-length and the second predeterminated frequency step-length can be equal, it can also be unequal, the present invention is real
It applies example and this is not limited in any way.
Fig. 5 is the schematic diagram of the distance of near field of the according to embodiments of the present invention one adjusting charging pile provided.As shown in figure 5,
Signal receiving device 1, signal receiving device 2, signal receiving device 3 and signal receiving device 4 are separately positioned on position 1, position
2, position 3 and position 4, and position 1, position 2, position 3 and position 4 are with the distance between 1 signal lamp of charging pile respectively
50cm, 45cm, 40cm and 35cm.In addition, Target near field distance range is set as between 40cm to 45cm, and pre- by first
If frequency step is set as 1KHz.When the micro-control unit of charging pile is with the carrier frequency control signal transmitting of received 38KHz
When device emits near-field-communication signal, signal receiving device 1, signal receiving device 2, signal receiving device 3 and signal receive dress
It sets 4 and is respectively received near-field-communication signal.Thus, it may be determined that in the case where carrier frequency is 38KHz, the near field of 1 signal lamp is logical
The distance of near field range for believing signal is more than or equal to 50cm, and Target near field distance range is between 40cm to 45cm, therefore,
The distance of near field range and Target near field distance range of near-field-communication signal mismatch, can be by the carrier frequency of near-field-communication signal
It is reduced to 37KHz.When the micro-control unit of charging pile is close with the carrier frequency control sender unit transmitting of received 37KHz
When the signal of communication of field, signal receiving device 2, signal receiving device 3 and signal receiving device 4 are respectively received near-field communication letter
Number, and signal receiving device 1 does not receive near-field-communication signal.Thus, it may be determined that in the case where carrier frequency is 37KHz, 1
The distance of near field range of the near-field-communication signal of signal lamp is between 45cm to 50cm, and Target near field distance range arrives for 40cm
Between 45cm, therefore, the distance of near field range and Target near field distance range of near-field-communication signal are mismatched, can be by near-field communication
The carrier frequency of signal is reduced to 36KHz.When the micro-control unit of charging pile controls signal with the carrier frequency of received 36KHz
When emitter emits near-field-communication signal, signal receiving device 2, signal receiving device 3 and signal receiving device 4 receive respectively
To near-field-communication signal, and signal receiving device 1 does not receive near-field-communication signal.Thus, it may be determined that be in carrier frequency
In the case where 36KHz, the distance of near field range of the near-field-communication signal of 1 signal lamp between 45cm to 50cm, and Target near field away from
From range between 40cm to 45cm, therefore, the distance of near field range of near-field-communication signal and Target near field distance range are not
Match, the carrier frequency of near-field-communication signal can be reduced to 35KHz.When the micro-control unit of charging pile is with received 35KHz's
When carrier frequency controls sender unit transmitting near-field-communication signal, signal receiving device 3 and signal receiving device 4 connect respectively
Near-field-communication signal is received, and signal receiving device 1 and signal receiving device 2 all do not receive near-field-communication signal.As a result, may be used
Determine in the case where carrier frequency is 35KHz, the distance of near field range of the near-field-communication signal of 1 signal lamp be 40cm to 45cm it
Between, and Target near field distance range, between 40cm to 45cm, therefore, the distance of near field range of near-field-communication signal is close with target
Field distance range matching, the carrier frequency that the micro-control unit of charging pile can store 35KHz are used for next time.
In an of the invention optional embodiment, except through determining the near-field-communication signal of sender unit transmitting
It, can also be logical by determining the near field of sender unit transmitting except the distance of near field of the carrier frequency to adjust near-field-communication signal
The carrier duty cycle of signal is believed to adjust the distance of near field of near-field-communication signal.It specifically, can be by institute in iterative processing for the first time
State the carrier duty cycle default value that signal characteristic parameter is determined as the near-field-communication signal of the sender unit transmitting；Non-
For the first time in iterative processing, if the upper limit value of the distance of near field range of the determination is less than or equal to the Target near field apart from model
The value of the lower limit value enclosed, the signal characteristic parameter that previous iteration is determined is determined plus the first default duty ratio step-length as current
Signal characteristic parameter value.Optionally, in non-iterative processing for the first time, if the lower limit of the distance of near field range of the determination
Value is greater than or equal to the upper limit value of the Target near field distance range, and the value for the signal characteristic parameter that previous iteration determines is subtracted
Value of the second default duty ratio step-length as currently determining signal characteristic parameter.Wherein, the described first default duty ratio step-length
Specially the carrier duty cycle of near-field-communication signal is between carrier duty cycle data two adjacent in gradually increasing process
Difference, for example, the first default duty ratio step-length can be 10% or 20%, the second default duty ratio step-length is specially close
Difference of the carrier duty cycle of field signal of communication between carrier duty cycle data two adjacent in gradually decrementing procedure, example
Such as, the described second default duty ratio step-length can be 10% or 20%.
Present inventor also found that the distance of near field of near-field-communication signal is logical also as near field in the course of the study
Believe the increase of the carrier duty cycle of signal and increases, the carrier wave of the distance of near field of near-field-communication signal also as near-field-communication signal
The reduction of duty ratio and reduce.Therefore, in iterative processing for the first time, signal characteristic parameter can be determined as to sender unit hair
The carrier duty cycle default value for the near-field-communication signal penetrated.In non-iterative processing for the first time, if it is determined that distance of near field range
Upper limit value be less than or equal to the lower limit value of Target near field distance range, the value of signal characteristic parameter that previous iteration determines is added
Value of the upper first default duty ratio step-length as currently determining signal characteristic parameter, to constantly increase sender unit
The distance of near field of the near-field-communication signal of transmitting, so that the distance of near field model of the near-field-communication signal of sender unit transmitting
It encloses and is matched with Target near field distance range.In non-iterative processing for the first time, if it is determined that distance of near field range lower limit value it is big
In or equal to Target near field distance range upper limit value, the value for the signal characteristic parameter that previous iteration determines is subtracted second and presets
Value of the duty ratio step-length as currently determining signal characteristic parameter, to be steadily decreasing the near field of sender unit transmitting
The distance of near field of signal of communication, so that the distance of near field range of the near-field-communication signal of sender unit transmitting is close with target
