Currently, the electronic device can realize positioning through a base station or Wi-Fi and the like.

The scheme of positioning through a base station or Wi-Fi generally determines a distance between an electronic device and a Wi-Fi hotspot by using signal strength of Wi-Fi signals received by the electronic device, or determines a distance between the electronic device and the base station according to arrival time or arrival time difference of mobile signals sent by different base stations and arriving at the electronic device. Since the location of the Wi-Fi hotspot or base station is known, the location of the electronic device can be determined based on the principles of triangulation.

However, in practice, it is found that due to the influence of factors such as the aging of the hardware performance of the electronic device or the change of the wireless network environment, the strength of signals received by the electronic device at the same position at different times may change, and the time when a mobile signal arrives at the electronic device may also change, so that the problem of frequent jump of a positioning position occurs, which indirectly affects the positioning experience of a user.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It is to be noted that the terms "comprises" and "comprising" and any variations thereof in the embodiments and drawings of the present invention are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

The embodiment of the invention discloses a positioning deviation rectifying method and a server, which can reduce the jump of a positioning position. The following are detailed below.

Example one

Referring to fig. 1, fig. 1 is a schematic flow chart of a positioning and deviation rectifying method according to an embodiment of the present invention. As shown in fig. 1, the positioning error correction method may include the following steps:

101. the server acquires first signal information of a plurality of first wireless signals received by the electronic equipment.

In the embodiment of the present invention, the electronic device may be a mobile terminal such as a mobile phone, a watch, a tablet computer, and the like, which is not limited in the embodiment of the present invention. In addition, the first wireless signal received by the electronic device may be a wireless network signal (e.g., Wi-Fi) transmitted by a wireless network hotspot, or may also be a mobile communication signal (e.g., 4G or 5G signal) transmitted by a base station, which is not limited in the embodiment of the present invention.

The first signal information acquired by the server may include a signal identifier of each first wireless signal, a time when the electronic device receives the first wireless signal, a received signal strength when the electronic device receives the first wireless signal, and the like.

102. The server judges whether a wireless signal matched with an area signal in any area signal set exists in the plurality of first wireless signals or not according to the first signal information; if yes, go to step 103; if not, the flow is ended.

In the embodiment of the present invention, the area signal set includes a plurality of area signals, and the area signals are wireless signals capable of covering an area corresponding to the area signal set. The regional signal set is pre-selected and stored in the database, and the server can match a plurality of first wireless signals with the regional signal set through the signal identifiers in the first signal information. Specifically, the manner of determining, by the server, whether a wireless signal matched with an area signal in any area signal set exists in the plurality of first wireless signals according to the first signal information may be:

judging whether a wireless signal which is the same as an area signal in any area signal set exists in the plurality of first wireless signals according to the signal identifier in the first signal information; if so, it can be determined that there is a wireless signal in the first wireless signals that matches a zone signal in any of the set of zone signals.

Further, the server may also consider the received signal strength of the first wireless signal when matching the plurality of first wireless signals with the set of area signals. That is to say, the manner of determining, by the server, whether there is a wireless signal matching with an area signal in any area signal set in the plurality of first wireless signals according to the first signal information may specifically be:

the server judges whether the wireless signals identical to the area signals in any area signal set exist in the plurality of first wireless signals according to the signal identification in the first signal information;

if so, judging whether the difference value between the received signal strength of the first wireless signal which is the same as the area signal and the received signal strength of the same area signal exceeds a preset difference value threshold value according to the received signal strength in the first signal information;

if not, it can be determined that there is a wireless signal in the first plurality of wireless signals that matches a zone signal in any of the set of zone signals.

The received signal strength of the area signal is the received signal strength of the electronic device when the area signal is received in the area, which is measured in advance.

103. And the server searches the correction positioning position associated with the matched area signal set according to the pre-stored association relation.

In the embodiment of the invention, the corrected positioning position is a positioning position obtained after correction. In the pre-stored association relationship, each corrected location position may be associated with at least one set of area signals, and the area signals included in the associated set of area signals are determined according to wireless signals received by the electronic device at the corrected location position. The corrected positioning position can be reported by the electronic equipment and corrected by a user of the electronic equipment; alternatively, the user of the server may perform the correction based on the preliminary positioning location reported by the electronic device.

104. And the server determines the positioning position of the electronic equipment at the current positioning according to the corrected positioning position.

In the embodiment of the invention, the server can directly determine the corrected positioning position as the positioning position of the electronic equipment for positioning at this time;

or, a second positioning position of the electronic device can be determined according to the plurality of first wireless signals, and whether the distance deviation between the second positioning position and the correction positioning position exceeds a preset distance threshold value is judged; if so, determining the corrected positioning position as the positioning position of the electronic equipment for the current positioning;

or, the second positioning position may be corrected by using the corrected positioning position, and the third positioning position obtained after correction may be determined as the positioning position of the current positioning.

As an optional implementation manner, after determining the location position of the electronic device located this time, the server may send the location position of the electronic device located this time to another control device bound to the electronic device, and the control device may initiate a location service based on the location position of the electronic device located this time, so as to send the location position of the electronic device located this time and service content of the location service to another execution device. The location service may include, among other things, a taxi pick-up service or a delivery service. By implementing the above embodiments, a user (e.g., a child) of the electronic device may share a location position to a user (parent) of the control device, and the user of the control device may initiate a location service through the control device, so that an executor or an execution device executing the location service may receive specific contents of the location service and the location position of the electronic device through the execution device, and thus may perform the corresponding location service.

For example, a parent may initiate a pickup service through a mobile phone (i.e., a control device), and a pickup person responsible for executing the pickup service may view a location where a child is located (i.e., a location position of the current location) through the mobile phone (i.e., an execution device). In a scenario where a child is delivered or a location service such as a delivery service is sought, the location of a person who needs to receive the location service in the same area is often fixed. For example, a child may generally walk to a bus station, a school doorway, and other conspicuous places to wait for pickup. If the positioning position of the electronic equipment used by the person needing to receive the position service frequently jumps, the position service executor or the executing equipment is easily confused, and the position service executor or the executing equipment is not favorably interfaced with the person receiving the position service.

In the embodiment of the present invention, the electronic device performs positioning by using the method described in fig. 1, and can determine the positioning location of the current positioning according to the corrected positioning location, so that the positioning result is relatively accurate and the jump of the positioning location can be reduced, thereby facilitating the docking between the executor of the location service or the execution device and the person receiving the location service.

It can be seen that, in the method described in fig. 1, the server finds out the corrected positioning location through the matching of the first wireless signal, and then determines the positioning location of this positioning according to the corrected positioning location. The corrected positioning position is relatively accurate because it is corrected. In addition, when the final positioning position is determined, the distance between the electronic equipment and the Wi-Fi hotspot or the base station determined according to the first wireless signal is not used for calculation, so that the influence of factors such as the received signal strength and the arrival time of the first wireless signal on the positioning result can be reduced, and the jump of the positioning position can be reduced.

Example two

Referring to fig. 2, fig. 2 is a schematic flow chart of a positioning and deviation rectifying method according to an embodiment of the present invention. As shown in fig. 2, the positioning error correction method may include the following steps:

201. the server acquires second signal information of a plurality of second wireless signals received by the electronic equipment in any area.

202. And the server acquires the corrected positioning position reported by the electronic equipment.

In the embodiment of the invention, the corrected positioning position is a positioning position obtained by correcting the preliminary positioning position determined according to the plurality of second wireless signals by using correction information input by a user of the electronic equipment.

Specifically, the manner in which the electronic device determines the preliminary positioning position according to the plurality of second wireless signals may be that the preliminary positioning position is determined according to the received signal strength of each second wireless signal or the arrival time of each second wireless signal when the electronic device receives the plurality of second wireless signals, and the following contents are not repeated.

As an alternative embodiment, after determining the preliminary positioning position, the electronic device may output a display map on a touch screen of the electronic device, and superimpose and display an icon indicating a position on the map at a position point corresponding to the preliminary positioning position;

receiving a dragging operation aiming at an icon, and determining a position point corresponding to a terminal point of the dragging operation on a map;

and determining the position of the corresponding position point of the end point of the dragging operation on the map as a corrected positioning position.

That is, the correction information input by the user of the electronic device may specifically be a drag operation for an icon on the map for indicating the position; the specific way of correcting the preliminary positioning position determined according to the plurality of second wireless signals by using the correction information input by the user of the electronic device is to determine the position of the position point corresponding to the end point of the dragging operation on the map as the corrected positioning position.

203. And the server screens out the wireless signals meeting the preset conditions from the plurality of second wireless signals according to the second signal information to be used as the area signals of the area so as to obtain an area signal set corresponding to the area.

In the embodiment of the present invention, the preset condition is a criterion for evaluating whether a certain second wireless signal is stable and reliable. Specifically, the preset condition may be at least: when the electronic equipment receives a certain second wireless signal, the receiving intensity of the second wireless signal exceeds a preset intensity threshold; or when the second wireless signal is a Wi-Fi signal, the device type of the hotspot device which transmits the Wi-Fi signal is a non-mobile terminal. That is, if the device type of the hotspot device emitting the Wi-Fi signal is a mobile terminal such as a mobile phone, the Wi-Fi signal may be considered to be unstable, and such unstable wireless signals should be excluded.

204. And the server establishes an incidence relation between the area signal set and the correction positioning position and stores the incidence relation.

In the embodiment of the present invention, as an optional implementation manner, the server may store the region signal set and the corrected location position in the form of a key value pair, and use the corrected location position as a key, where the region signal set is a value in the key value pair, so as to meet a high concurrent data access requirement.

By performing the above steps 201 to 204, the correlation between the corrected positioning position and the filtered and determined area signal set can be established. When the electronic device needs to perform positioning again, the following steps 205 to 209 may be performed by using the above-mentioned association relationship.

205. The server acquires first signal information of a plurality of first wireless signals received by the electronic equipment.

In this embodiment of the present invention, as an optional implementation manner, after receiving the first signal information reported by the electronic device, and before performing the following step 206, the server may further perform the following steps:

the server acquires a unique user identity reported by the electronic equipment; the unique identity of the user can be an identification code input by a user of the electronic equipment, and can also be fingerprint information, iris information or ear canal texture information and the like of the user of the electronic equipment;

the server judges whether the user is a legal user according to the unique identity of the user;

if so, step 206, described below, is performed.

By implementing the above embodiment, the server may perform identity authentication on the user of the electronic device initiating the location service before providing the location service to the electronic device; after the authentication is legal, the electronic equipment is positioned, so that an illegal positioning request initiated by a hacker through invading the electronic equipment can be identified, the leakage probability of the positioning data of the electronic equipment is reduced, and the privacy safety of a legal user of the electronic equipment is guaranteed.

206. The server judges whether a wireless signal matched with an area signal in any area signal set exists in the plurality of first wireless signals or not according to the first signal information; if yes, go to step 207; if not, the flow is ended.

207. The server judges whether the first wireless signal matched with the area signal in the area signal set meets the deviation rectifying condition; if so, go to step 208; if not, the flow is ended.

In the embodiment of the present invention, the deviation rectifying condition at least includes: the number of first wireless signals matched with the area signals in the area signal set exceeds a preset number threshold; or the received signal strength of the first wireless signal matched with the area signal in the area signal set exceeds a preset strength threshold. Optionally, the intensity threshold included in the deviation rectification condition may be the same as the intensity threshold in the preset condition adopted in the process of screening the area signal, so as to determine whether the first wireless signal currently received by the electronic device is stable according to the intensity of the received signal.

If the first wireless signal matched with the area signal meets the deviation rectifying condition, the first wireless signal can be considered to be credible and can be used for positioning calculation. So that the steps 208 to 209 described below are continuously performed.

208. And the server searches the correction positioning position associated with the matched area signal set according to the pre-stored association relation.

209. And the server determines the positioning position of the electronic equipment at the current positioning according to the corrected positioning position.

As an optional implementation manner, after the server performs step 209 to determine the location position of the electronic device at this time of location, the server may further query whether public infrastructure such as a street lamp and a station exists within a range where the location position of the electronic device at this time is smaller than a preset distance threshold, and if so, acquire a unique facility identifier of the public infrastructure located within the area range; and after receiving the location service initiated by the control equipment, sending the unique facility identification of the public infrastructure, the positioning location of the electronic equipment at the current positioning and the service content of the location service to the execution equipment. Wherein, if the public infrastructure is a street lamp, the unique facility identification of the public infrastructure can be the identity number of the street lamp; if the public infrastructure is a station, the unique facility identification of the public infrastructure may be the station's stop plate name.

Implementing the above-described embodiments, after a parent (i.e., a user of the control device) initiates the location service, the location position of the child (i.e., a user of the electronic device), the service content of the location service, and the unique facility identification of the landmark object (i.e., the public infrastructure) around the location position of the child may be transmitted to the execution device, so that the user of the execution device or the execution device itself may be quickly located to a possible location of the child (i.e., a user of the electronic device) through the landmark object.

It can be seen that in the method described in fig. 2, the server may receive the corrected positioning position that is artificially corrected, and screen out a relatively stable and reliable wireless signal as the area signal, so as to establish an association relationship between the corrected positioning position and the area signal set for subsequent positioning. Further, in the method described in fig. 2, the server may further determine whether the received first wireless signal meets the deviation rectification condition, so that when the first wireless signal is verified to be authentic, the server determines the corresponding area signal set and the corresponding corrected positioning position according to the first wireless signal, so as to determine the positioning position of the current positioning based on the corrected positioning position, and thus, the accuracy of the positioning may be improved.

EXAMPLE III

Referring to fig. 3, fig. 3 is a schematic flow chart of a positioning and deviation rectifying method according to an embodiment of the present invention. As shown in fig. 3, the positioning error correction method may include the following steps:

301. the server acquires second signal information of a plurality of second wireless signals received by the electronic equipment in any area.

302. And the server acquires the corrected positioning position reported by the electronic equipment.

303. And the server screens out the wireless signals meeting the preset conditions from the plurality of second wireless signals according to the second signal information to be used as the area signals of the area so as to obtain an area signal set corresponding to the area.

304. And the server establishes an incidence relation between the area signal set and the correction positioning position and stores the incidence relation.

305. The method comprises the steps that a server obtains an equipment identifier of electronic equipment, and identifies whether the equipment type of the electronic equipment is wearable equipment or not according to the equipment identifier; if yes, go to step 306; if not, the flow is ended.

In the embodiment of the invention, the battery capacity of the wearable equipment is smaller, and the wearable equipment is sensitive to energy consumption. Therefore, when the device type of the electronic device is determined to be the wearable device, the following steps 306 to 310 are executed, and the server performs the positioning calculation of the electronic device, so that the power consumption of the wearable device can be reduced compared with the calculation of the positioning position locally on the wearable device.

306. The server acquires first signal information of a plurality of first wireless signals received by the electronic equipment.

307. The server judges whether a wireless signal matched with an area signal in any area signal set exists in the plurality of first wireless signals or not according to the first signal information; if yes, go to step 207; if not, the flow is ended.

308. The server judges whether the first wireless signal matched with the area signal in the area signal set meets the deviation rectifying condition; if so, go to step 309; if not, the flow is ended.

In the embodiment of the present invention, the deviation rectifying condition at least includes: the number of first wireless signals matched with the area signals in the area signal set exceeds a preset number threshold; or the received signal strength of the first wireless signal matched with the area signal in the area signal set exceeds a preset strength threshold.

309. And the server searches the correction positioning position associated with the matched area signal set according to the pre-stored association relation.

310. The server identifies the area type of an area corresponding to an area signal set matched with the plurality of first wireless signals, and judges whether the area corresponding to the matched area signal set is a preset safe area or not according to the area type; if yes, go to step 311; if not, step 312 is performed.

In the embodiment of the present invention, the secure area may be an area that is authenticated in advance, and an area that a user of an electronic device such as a school, a patch class, a home frequently enters and exits may be authenticated as the secure area.

311. And the server determines the positioning position of the electronic equipment at the current positioning according to the corrected positioning position.

In the embodiment of the invention, the electronic device can be a smart watch, a learning tablet, a smart phone or the like worn by a child. If the type of the matched region (i.e., the region corresponding to the matched region signal set) is a safe region, it can be considered that the child is currently in a safer environment, the urgency for monitoring the positioning position of the child is low, and the accuracy requirement for the positioning position is generally low, so that the corrected positioning position can be directly used as the positioning position of the current positioning, and a fixed corrected positioning position is used as the result of the current positioning. By implementing the embodiment, the urgency degree of the positioning requirement can be considered during positioning, so that the calculation amount and the positioning precision of the positioning calculation are balanced, namely, a relatively accurate positioning result which can meet the requirement of a user is provided by using relatively less calculation amount.

312. The server determines a second positioning position of the electronic equipment according to the plurality of first wireless signals received by the electronic equipment, corrects the second positioning position by using the corrected positioning position, and determines a third positioning position obtained after correction as the positioning position of the current positioning.

In the embodiment of the invention, if the matched area is not a safe area, the safety problem of the child is easy to worry, the movement of the child needs to be concerned, the urgency degree of monitoring the positioning position of the child is higher, and the requirement on positioning accuracy is also higher. Therefore, step 312 is executed to correct the second positioning location determined according to the first wireless signal by using the corrected positioning location, so as to obtain a positioning location with higher accuracy. Optionally, the specific implementation of the correction may be to calculate an average value of the second positioning location and the corrected positioning location as a third positioning location obtained after the correction.

It can be seen that implementing the method described in fig. 3, an association between the corrected position location and the filtered regional signal set can be established for subsequent positioning; after the received first wireless signal is judged to meet the deviation rectifying condition, the corresponding area signal set and the corresponding correction positioning position are determined according to the first wireless signal, so that the positioning position of the positioning is determined based on the correction positioning position, and the positioning accuracy is improved. Further, in the method described in fig. 3, after the electronic device is determined to be a wearable device, the method described in fig. 3 is performed to locate the electronic device, so that power consumption of the wearable device can be reduced. Furthermore, in the method described in fig. 3, if it is determined that the matched area is a safe area, the corrected positioning position is directly determined as the positioning position of the current positioning, which can balance the calculation amount and the positioning accuracy of the positioning calculation, so as to provide a relatively accurate positioning result capable of meeting the user requirement with relatively less calculation amount; and if the matched area is judged not to be the safe area, correcting the second positioning position by using the corrected positioning position to obtain a positioning position with higher precision, so that the activity condition of the child in the unsafe area can be accurately mastered, and the safe reminding can be conveniently carried out.

Referring to fig. 4, fig. 4 is a schematic structural diagram of a server according to an embodiment of the present invention. As shown in fig. 4, the server may include:

a first obtaining unit 401, configured to obtain first signal information of a plurality of first wireless signals received by an electronic device;

a first determining unit 402, configured to determine whether a wireless signal matching a regional signal in any regional signal set exists in the plurality of first wireless signals according to the first signal information; the area signal is a wireless signal capable of covering an area corresponding to the area signal set;

as an optional implementation manner, the manner of determining, by the first determining unit 402, whether there is a wireless signal matching with a zone signal in any zone signal set in the plurality of first wireless signals according to the first signal information may specifically be:

a first determining unit 402, configured to determine whether there is a wireless signal that is the same as a regional signal in any regional signal set in the plurality of first wireless signals according to the signal identifier in the first signal information; if yes, the wireless signals matched with the area signals in any area signal set exist in the first wireless signals;

or, the first judging unit 402 is configured to judge whether there is a wireless signal that is the same as an area signal in any area signal set in the plurality of first wireless signals according to the signal identifier in the first signal information; if so, judging whether the difference value between the received signal strength of the first wireless signal which is the same as the area signal and the received signal strength of the same area signal exceeds a preset difference value threshold value according to the received signal strength in the first signal information; if not, it can be determined that there is a wireless signal in the first plurality of wireless signals that matches a zone signal in any of the set of zone signals.

A searching unit 403, configured to search, after the first determining unit 402 determines that there is a wireless signal matching with an area signal in any area signal set in the plurality of first wireless signals, a corrected positioning position associated with the matching area signal set according to a pre-stored association relationship; the correction positioning position is a positioning position obtained after correction;

and a positioning unit 404, configured to determine a positioning position of the electronic device at this time according to the corrected positioning position.

The positioning unit 404 may be specifically configured to directly determine the corrected positioning position as the positioning position of the electronic device at this time; or, a second positioning position of the electronic device can be determined according to the plurality of first wireless signals, and whether the distance deviation between the second positioning position and the correction positioning position exceeds a preset distance threshold value is judged; if so, determining the corrected positioning position as the positioning position of the electronic equipment for the current positioning; or, the second positioning position may be corrected by using the corrected positioning position, and the third positioning position obtained after correction may be determined as the positioning position of the current positioning.

In addition, as an optional implementation manner, in the server shown in fig. 4, after the positioning unit 404 determines the positioning location of the electronic device located this time, the positioning unit may be further configured to send the positioning location of the electronic device located this time to another control device bound to the electronic device, so that the control device may initiate location service based on the positioning location of the electronic device located this time;

and the system can also be used for receiving the positioning location service initiated by the control equipment and sending the positioning location of the electronic equipment at this time and the service content of the location service to another execution equipment.

It can be seen that, with the server shown in fig. 4, the corrected positioning position can be found through matching of the wireless signals, and the positioning position of the current positioning is determined according to the corrected positioning position. The corrected positioning position is relatively accurate because it is corrected. In addition, when the final positioning position is determined, the distance between the electronic equipment and the Wi-Fi hotspot or the base station determined by the first wireless signal is not used for calculation, so that the influence of factors such as the received signal strength and the arrival time of the first wireless signal on the positioning result can be reduced, and the jump of the positioning position can be reduced.

Referring to fig. 5, fig. 5 is a schematic structural diagram of a server according to an embodiment of the present invention. The server shown in fig. 5 is optimized by the server shown in fig. 4. As shown in fig. 5, the server may further include:

Further optionally, the server shown in fig. 5 may further include:

the searching unit 403 is specifically configured to search, after the first determining unit 402 determines that there is a wireless signal matching with the area signal in any area signal set in the plurality of first wireless signals and the second determining unit 408 determines that the first wireless signal matching with the area signal in the area signal set meets the deviation rectification condition, a calibration positioning position associated with the matching area signal set according to a pre-stored association relationship;

wherein, the condition of rectifying at least includes: the number of first wireless signals matched with the area signals in the area signal set exceeds a preset number threshold; or the received signal strength of the first wireless signal matched with the area signal in the area signal set exceeds a preset strength threshold.

In addition, as an alternative implementation, in the service shown in fig. 5:

As another optional implementation manner, in the server shown in fig. 5, after the positioning unit 404 determines the positioning position of the electronic device at this time, the positioning unit may be further configured to query whether public infrastructure such as a street lamp and a station exists within a range that is less than a preset distance threshold from the position of the electronic device at this time, and if the public infrastructure exists, obtain a unique facility identifier of the public infrastructure located within the area range;

and after receiving the location service initiated by the control equipment, sending the unique facility identification of the public infrastructure, the positioning location of the electronic equipment at the current positioning and the service content of the location service to the execution equipment. Wherein, if the public infrastructure is a street lamp, the unique facility identification of the public infrastructure can be the identity number of the street lamp; if the public infrastructure is a station, the unique facility identification of the public infrastructure may be the station's stop plate name.

It can be seen that, when the server shown in fig. 5 is implemented, the corrected positioning position which is artificially corrected may be received, and a relatively stable and reliable wireless signal may be screened out as an area signal, so as to establish an association relationship between the corrected positioning position and an area signal set for subsequent positioning.
