As long as it can represent that the electronic equipment belongs to the possibility in each region.
Specifically, in the first implementation, it is more accordingly the multiple first wireless signal can be based on
The temporal signatures of individual first signal value, calculate the parameter value.In the second implementation, it can be based on
The frequency domain character of the multiple first signal value, calculates the parameter value.Exemplarily, the time domain is special
Sign can be embodied by the amplitude of the RSSI value of first wireless signal.The frequency domain character can be by described
The spectral characteristic of the RSSI value of first wireless signal and embody.
Thus, the amplitude or spectral characteristic of the RSSI value of multiple first wireless signals be may compare.First nothing

Calculate or the other modes of classification etc. carry out calculating parameter value.
Then, in step S40, based on the second wireless singal, the parameter value is adjusted.
Here, for convenience, the adjustment is properly termed as adjusting for the first time.
Specifically, can the secondary signal value based on same second wireless singal in the first implementation
Change, the parameter value is adjusted for the first time.The secondary signal value represents second wireless communication
Number temporal signatures and the second wireless singal frequency domain character in it is at least one.Exemplarily, institute
Stating temporal signatures can be embodied by the amplitude of the RSSI value of the second wireless singal.The frequency domain character can
Embodied by the spectral characteristic of the RSSI value of the second wireless singal., can in the second implementation
The change of difference between the secondary signal value based at least two second wireless singals, to the parameter
Value is adjusted for the first time.It will be appreciated by those skilled in the art that above-described implementation is merely illustrative,
Above-mentioned different implementations can also be combined as described first to realize by the localization method of the embodiment of the present invention
Secondary adjustment.
Step S40 processing is described in detail next, with reference to Fig. 3.
Fig. 3 is to be shown in localization method according to embodiments of the present invention to adjust the parameter value for the first time
The flow chart of one example of whole processing.
As shown in figure 3, when being adjusted for the first time to the parameter value, first, in step S410, base
In the second wireless singal, judge whether to reach reset time point.
Specifically, in the first implementation as described above, exemplarily, it can determine whether second nothing
Whether the amplitude of the RSSI value of line signal changes.When the RSSI value of the second wireless singal is shaken
When width changes, it is determined that reaching reset time point.On the other hand, as the RSSI of the second wireless singal
When the amplitude of value does not change, it is determined that without arrival reset time point.Alternatively or with this in combination,
It can determine whether the spectral characteristic of the RSSI value of the second wireless singal changes.When second nothing
When the spectral characteristic of the RSSI value of line signal changes, it is determined that reaching reset time point.On the other hand,
When the spectral characteristic of the RSSI value of the second wireless singal does not change, it is determined that heavy without reaching
Put time point.First implementation be particularly suitable for use in environment it is relatively stable, the second of second wireless singal
The slow scene of signal value changes, so as to advantageously improve the response speed of zone location.
In addition, in the second implementation as described above, exemplarily, at least two second are can determine whether
Whether the difference between the RSSI value of wireless signal changes.When at least two second wireless singal
RSSI value between difference when changing, it is determined that reaching reset time point.On the other hand, when described
When difference between the RSSI value of at least two second wireless singals does not change, it is determined that without reaching
Reset time point.In addition, in the case of multiple second wireless singals, multiple second wireless communications are can determine whether
Whether difference number between any two changes, to judge whether to reach reset time point.Second realization
Mode is particularly suitable for use in, and environment is relatively unstable, secondary signal value of second wireless singal is easily by environmental factor
The scene of influence, so that region is more stable and reliable.
Next, when determine reach reset time point when, the processing proceeds to step S420.In step
S420, the parameter value is reset, as the parameter value after first adjustment.
More specifically, in the first implementation, it is default the parameter value can simply to be reset to some
Fixed value, for example, 0.
, can the first signal value based on current time, second letter at current time in the second implementation
Number value and current time exercise data at least one and current time parameter value, to described
Parameter value is reset.The exercise data represents the motion feature of the electronic equipment, and it will later
It is described in detail.First signal value represents the temporal signatures of first wireless signal and first nothing
At least one in the frequency domain character of line signal, the secondary signal value represents the second wireless singal
It is at least one in temporal signatures and the frequency domain character of the second wireless singal.
For example, in the case where representing the parameter value by votes, exemplarily, can be by following
Expression formula (1) come determine reset after parameter value：
V=k × v'+p × v1+q×v2+s×v3 (1)
Wherein, v represents the poll after resetting, and v ' represents the poll at current time, v1Expression is based only upon currently
First wireless signal at moment and the poll calculated, v2Expression is based only upon the second wireless singal at current time
And the poll calculated, v3The poll that expression is based only upon the exercise data at current time and calculated, k, p, q
It is respectively respective weight parameter with s, can be set as suitably desired by those skilled in the art.
For example, can be according to the first wireless signal, second wireless singal and exercise data in the scene applied
The degree of reliability and corresponding weight parameter is set.In addition, v1Computational methods reference picture 2 the step of
S30 is described in detail, v2And v3Computational methods and v1Computational methods it is similar, be not repeated herein.
It is pointed out that as described above, the first wireless signal, second wireless singal and fortune can be based only upon
At least one parameter value to calculate after resetting in dynamic data.That is, can be by by above-mentioned expression
One or more of k, p, q and s in formula (1) are arranged to 0, and calculate the parameter value after resetting.
Thus, the parameter value is reset by calculating as described above, as the parameter value after first adjustment.
It will be appreciated by those skilled in the art that above-described reset mode is merely illustrative.According to the present invention
The localization method of embodiment can suitably reset the parameter value by other various modes.
On the other hand, when judgement does not reach reset time point, the processing proceeds to step S430.
Step S430, the parameter value is directly exported as the parameter value after first adjustment.
Next, return Fig. 2 continuing on.After the parameter value after obtaining first adjustment, the present invention
The localization method of embodiment proceeds to step S50.In step S50, based on the parameter value after first adjustment,
The region residing for the electronic equipment is determined from the multiple region.
Specifically, for example, in the case where the parameter value is poll, determined from the multiple region
The maximum region of poll, as the region residing for the electronic equipment.In the feelings that the parameter value is probability
Under condition, probability highest region is determined from the multiple region, as the area residing for the electronic equipment
Domain；Etc..
Thus, localization method according to embodiments of the present invention realizes electricity by referring to the processing described in Fig. 2
The positioning in region residing for sub- equipment.
Although it is pointed out that in the flowchart of fig. 2 each step S10-S50 necessarily sequentially to show,
But this does not imply that each step must be performed with shown order.Those skilled in the art can be as needed
The processing of each step is performed in any suitable order.For example, step S10 and step S20 place
Reason can be performed in parallel；Etc..
In localization method according to embodiments of the present invention, positioned based on different types of wireless signal,
Thus, it is possible to obtain more accurate and more stable zone location result.
In addition, in localization method according to embodiments of the present invention, join being calculated based on the first wireless signal
During numerical value, size that not only can be simply based on the first signal value of the first wireless signal and obtain
The scope of corresponding parameter value, is also based on the change of the first signal value of the first wireless signal and calculates ginseng
Numerical value, so as to reduce the interference that external environment is brought, improve the reliability of zone location.
In addition, in localization method according to embodiments of the present invention, based on relatively more stable, coverage
Wider array of second wireless singal is adjusted to parameter value, is caused so as to correct because of history value
Accumulated error, and therefore can improve the judgement speed of zone location.
Above in relation in the localization method described in Fig. 2, the parameter value is entered based on second wireless singal
Adjustment is gone.In embodiments of the present invention, to make parameter value more smooth, the parameter value can also be entered
The further adjustment of row.
The further processing of the localization method of the embodiment of the present invention is described next, with reference to Fig. 4.
Fig. 4 is to show the step S50 in localization method according to embodiments of the present invention as shown in Figure 2
Detailed processing flow chart.Specifically, localization method according to embodiments of the present invention can also receive expression
The exercise data of the motion feature of the electronic equipment.Exemplarily, can be equipped with the electronic equipment
PDR (Pedestrian Dead Reckoning, pedestrian's dead reckoning) inertial sensor.The inertia
Sensor can be realized by the various sensors of acceleration transducer, gyroscope, Magnetic Sensor etc..
Exemplarily, the inertial sensor can gather the acceleration magnitude of the electronic equipment, magnitude of angular velocity etc.
Value is used as the exercise data.Alternatively, the data that can be also gathered the inertial sensor pass through one
Fixed processing, and using the data after processing as the exercise data.For example, can be by the acceleration magnitude
Velocity amplitude obtained from integration is as the exercise data；Etc..The processing for receiving exercise data can
Performed with any time before step S50 as shown in Figure 2 processing.
Thus, as shown in figure 4, obtained by step S40 processing the parameter value after first adjustment it
Afterwards, in step S510, based on the exercise data, the parameter value after the first adjustment is carried out secondary
Adjustment.
Carry out the processing of secondary adjustment to the parameter value in step S510 next, with reference to Fig. 5 descriptions
Detailed process.As shown in figure 5, first, in step S5110, institute is determined based on the exercise data
State the motion state residing for electronic equipment.Specifically, based on the exercise data, determine that the electronics is set
It is standby to be in the first motion state advanced in same direction, the second motion state turned in situ, still
The 3rd static motion state in situ.More specifically, velocity amplitude and angle speed are included with the exercise data
In case of angle value, when the velocity amplitude is more constant, represent the electronic equipment in same direction
Advance, such as advance in a forward direction.In addition, when the velocity amplitude is zero or smaller, angle speed
When angle value is more constant, represent that the electronic equipment is in situ or approximate pivot stud.In addition, when described
When velocity amplitude and the magnitude of angular velocity are all zero or are approximately zero, represent that the electronic equipment is static or relative
It is static.Certainly, example is the foregoing is only, the localization method of the embodiment of the present invention can be according to the motion
The species of data is different and judges the motion state residing for the electronic equipment by different way.For example,
In the case where the exercise data includes acceleration magnitude, it is contemplated that user's its acceleration in normal gait
Value, which changes with time, is presented preassigned pattern, therefore, when the preassigned pattern is presented in the acceleration magnitude
Judge that the electronic equipment advances in the same direction；Etc..
When it is determined that the electronic equipment is in the first motion state, processing is carried out to step S5120, and
The parameter value after the first adjustment is filtered with the first filtering mode.Now, due to the electronics
Equipment is in the motion state advanced in certain direction, therefore filtering now is mainly used in reducing environmental disturbances,
Especially because motor behavior and its change in location of electronic equipment and bring signal value upheaval.In this feelings
, can be by setting the smooth signal value of filtering time window (for example, RSSI value) to filter out high frequency under condition
Clutter composition, so that it is guaranteed that the RSSI value in time window on a certain position keeps constant, not too much
Vibration or jump.Therefore, in the case, be considered as carry electronic equipment user gait of march,
The sample frequency of displacement and RSSI value is filtered.Exemplarily, following formula (2) can be passed through
To determine filter window：
Wherein, NTIt is identified filter window, d is the step-length of user, and v is the walking speed of user,
Both of which can be obtained by the sensing of PDR sensors.TperiodIt is RSSI Sampling time periods, its
It is the time cycle that electronic equipment receives the first wireless signal, can be by the localization method of the embodiment of the present invention
It is obtained ahead of time.
In addition, when it is determined that the electronic equipment is in the second motion state, processing is carried out to step
S5130, and keep the parameter value after first adjustment constant.
In addition, when it is determined that the electronic equipment is in three motion states, processing is carried out to step
S5140, and the parameter value after the first adjustment is filtered with the second filtering mode.Second filter
Ripple mode is different from first filtering mode.Now, because electronic equipment is substantially static, therefore now
Filtering be mainly used in reducing the vibration or jump of the RSSI value caused by the internal factor of frequency hopping etc..
In the case, can be reduced by being averaged RSSI sampled values in whole frequency range due to wrong caused by frequency hopping
Erroneous judgement.Exemplarily, filter window can be determined by following formula (3)：
Wherein, NTIt is identified filter window, TNchannelIt is all broadcast for scanning the first wireless signal
The time cycle of passage, T 'periodIt is the sampling period of PDR sensing datas, and m is multiple parameter,
For natural number.m、TNchannelAnd T 'periodIt can be obtained ahead of time by the localization method of the embodiment of the present invention.
Thus, by the processing of the step S5110-S5140 in Fig. 5, for different situations with different filters
