Detailed Description
Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present application are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the application and should not be taken as limiting the application with respect to other embodiments that are not detailed herein.
It is understood that the execution subject of the embodiment of the present application may be an electronic device such as a smart phone, a tablet computer, a smart watch, a conversation watch, a sports watch, or a smart band.
Referring to fig. 1, fig. 1 is a schematic view illustrating a first process of a positioning method provided in an embodiment of the present application, where the positioning method is applicable to an electronic device, and the process may include:
101. a location request is received.
For example, a user may click or press a "locate" button in the electronic device. The electronic device pops up a selection box to prompt the user to select to perform multipoint positioning or GPS positioning and the like. And if the user selects to perform multipoint positioning, the electronic equipment receives a positioning request.
Alternatively, a virtual key may be newly added to the electronic device, and the user may click or press the virtual key. When the user clicks or presses the virtual key, the electronic device receives the positioning request.
Alternatively, the user may draw a preset gesture on the screen of the electronic device, and when the preset gesture is received by the electronic device, the positioning request is received. The preset gesture is preset by a user and is associated with the positioning method provided by the embodiment of the application.
Alternatively, the user may speak a preset voice close to the electronic device, such as "please perform multi-point positioning", and when the electronic device receives the preset voice, the positioning request is received.
102. And searching the access points according to the positioning request to determine at least three searched access points.
For example, upon receiving a location request, the electronic device may search for access points based on the location request to determine at least three searched access points.
The access point may be a router for accessing wireless devices, such as electronic devices, into a wired network. When the electronic device is in the coverage area of the access point's signal, the electronic device may search for the access point. For example, if the electronic device searches for at least one access point, the electronic device may present the searched at least one access point in a list.
It should be noted that, in the embodiment of the present application, if the electronic device only searches for two or less access points, the electronic device may not directly perform the processing. Alternatively, the electronic device may generate a prompt to prompt the user that the multi-point positioning is not possible. The prompt message may be a text message or a voice message.
103. The location information for each access point is determined to obtain at least three location information.
For example, after determining at least three access points, the electronic device may determine the location information of each access point to obtain at least three location information.
For example, the access point location information base may be obtained from a location service provider in advance and stored into the electronic device. The access point position information base comprises identification information of a plurality of access points and corresponding position information thereof. After the electronic device determines at least three access points, the electronic device may obtain identification information of each access point. And then, whether identification information matched with the identification information of each access point exists in the access point position information base or not is detected in sequence. When it is detected that identification information matching the identification information of each access point exists in the access point location information base, the electronic device may obtain location information corresponding to the identification information, and determine the location information as the location information of each access point.
For example, assume that the electronic device determines four access points. Access points a1, a2, A3, and a4, respectively. The electronic device may obtain the identification information of a 1. The electronic device may then detect whether there is target identification information in the access point location information base that matches the identification information of a 1. If the location information exists, the location information corresponding to the target identification information is determined as the location information of the access point a 1. Next, the electronic device may acquire the identification information of a 2. The electronic device may then detect whether there is target identification information in the access point location information base that matches the identification information of a 2. If the location information exists, the location information corresponding to the target identification information is determined as the location information of the access point a 2. Subsequently, the electronic device may acquire the identification information of a 3. The electronic device may then detect whether there is target identification information in the access point location information base that matches the identification information of a 3. If the location information exists, the location information corresponding to the target identification information is determined as the location information of the access point a 3. Finally, the electronic device may obtain the identification information of a 4. The electronic device may then detect whether there is target identification information in the access point location information base that matches the identification information of a 4. If the location information exists, the location information corresponding to the target identification information is determined as the location information of the access point a 4.
Also for example, assume that the electronic device determines four access points. Access points a1, a2, A3, and a4, respectively. The electronic device may use the first thread to obtain the identification information of a 1. The electronic device may then use this first thread to detect whether there is target identification information in the access point location information base that matches the identification information of a 1. If the location information exists, the location information corresponding to the target identification information is determined as the location information of the access point a 1. Meanwhile, the electronic device may acquire the identification information of a2 using the second thread. The electronic device may then employ the second thread to detect whether there is target identification information in the access point location information base that matches the identification information of a 2. If the location information exists, the location information corresponding to the target identification information is determined as the location information of the access point a 2. Meanwhile, the electronic device may acquire the identification information of a3 by the third thread. The electronic device may then employ the third thread to detect whether there is target identification information in the access point location information base that matches the identification information of a 3. If the location information exists, the location information corresponding to the target identification information is determined as the location information of the access point a 3. Meanwhile, the electronic device may acquire the identification information of a4 using the fourth thread. The electronic device may then employ a fourth thread to detect whether there is target identification information in the access point location information base that matches the identification information of a 4. If the location information exists, the location information corresponding to the target identification information is determined as the location information of the access point a 4. And the position information of a plurality of access points is determined simultaneously by adopting multithreading, so that the processing time of the electronic equipment can be greatly saved.
104. And determining the distance between each access point and the electronic equipment to obtain at least three distances.
For example, after determining at least three access points, the electronic device may determine a distance between each access point and the electronic device to obtain at least three distances.
For example, the electronic device can determine a signal strength of each access point. Then, the electronic device may determine the distance between each access point and the electronic device according to the signal strength of each access point and the preset corresponding relationship between the signal strength and the distance, so as to obtain at least three distances.
It should be noted that the process 103 and the process 104 can be executed simultaneously. The process 103 may be executed first, and then the process 104 may be executed; or, the process 104 is executed first, and then the process 103 is executed, which is not limited in this respect.
105. And determining the position of the electronic equipment according to the at least three pieces of position information and the at least three distances.
For example, after the electronic device obtains at least three pieces of location information and at least three distances, the electronic device may determine the location of the electronic device according to the at least three pieces of location information and the at least three distances.
For example, the location of the electronic device may be determined as follows: location information for at least three access points may be obtained. Wherein the location information of the at least three access points may include locations of the at least three access points. Then, the position of each access point can be used as a circle center, and the distance between each access point and the electronic device is used as a radius to draw a circle, so as to determine three circles, wherein the intersection point of the three circles is the position of the electronic device.
In the embodiment of the application, the specific position of the electronic device can be determined by determining the positions of the at least three access points and the distances between the at least three access points and the electronic device, and in a scene with weak GPS signals, the positioning method provided by the embodiment of the application can improve the positioning accuracy compared with the GPS positioning using weak signals.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a second process of a positioning method according to an embodiment of the present application, where the positioning method is applicable to an electronic device, and the process may include:
201. the electronic device receives a location request.
For example, a user may click or press a "locate" button in the electronic device. The electronic device pops up a selection box to prompt the user to select to perform multipoint positioning or GPS positioning and the like. And if the user selects to perform multipoint positioning, the electronic equipment receives a positioning request.
Alternatively, a virtual key may be newly added to the electronic device, and the user may click or press the virtual key. When the user clicks or presses the virtual key, the electronic device receives the positioning request.
Alternatively, the user may draw a preset gesture on the screen of the electronic device, and when the preset gesture is received by the electronic device, the positioning request is received. The preset gesture is preset by a user and is associated with the positioning method provided by the embodiment of the application.
Alternatively, the user may speak a preset voice close to the electronic device, such as "please perform multi-point positioning", and when the electronic device receives the preset voice, the positioning request is received.
202. The electronic device searches for access points according to the positioning request to determine at least three searched access points.
For example, upon receiving a location request, the electronic device may search for access points based on the location request to determine at least three searched access points.
The access point may be a router for accessing wireless devices, such as electronic devices, into a wired network. When the electronic device is in the coverage area of the access point's signal, the electronic device may search for the access point. If the electronic device searches for at least one access point, the electronic device may present the searched at least one access point in a form of a list.
It should be noted that, in the embodiment of the present application, if the electronic device only searches for two or less access points, the electronic device may not directly perform the processing. Alternatively, the electronic device may generate a prompt to prompt the user that the multi-point positioning is not possible. The prompt message may be a text message or a voice message.
203. The electronic device determines identification information for each access point.
For example, when the searched at least three access points are determined, the electronic device may determine the identification information of each access point. Wherein the identification information uniquely identifies each access point. For example, the identification information may be a MAC address, i.e., a physical address, of the access point.
For example, the access point may broadcast the physical address outward. When an access point is searched, the electronic device may acquire a physical address broadcast by the access point, and determine the physical address as the identification information of the access point.
204. The electronic equipment determines the position information of each access point according to the identification information of each access point and a preset position information base to obtain at least three pieces of position information, wherein the preset position information base comprises the identification information of a plurality of access points and the position information corresponding to the identification information.
It should be noted that, in this embodiment, before the process 201, the electronic device may further download a preset location information base from the server, where the location information of each access point in the preset location information base is determined according to the location information corresponding to the plurality of electronic devices when the corresponding access point is searched, and the distances between the plurality of electronic devices and the corresponding access point when the corresponding access point is searched.
In an earlier stage, when the electronic device searches for at least one access point, the electronic device may obtain identification information of each of the at least one access point, a distance between each of the at least one access point and the electronic device, and location information of the electronic device. The electronic device may then transmit location information of the electronic device, identification information of each access point, and a distance of each access point from the electronic device to a server. When at least three electronic devices search for the same access point, each of the at least three electronic devices can acquire information such as a distance between the electronic device and the access point, identification information of the access point, and location information of the electronic device, and send the information to the server. The server may then determine location information for the access point based on the information. Then, the server may establish a preset location information base, associate the location information of the access point with the identification information of the access point, and store the association into the preset location information base. The identification information may be a MAC address, i.e., a physical address, of the access point.
As shown in fig. 3, after obtaining the location information of the electronic device D1, the location information of the electronic device D2, the location information of the electronic device D3, the distance D1 between the location of the electronic device D1 and the location of the access point a, the distance D2 between the location of the electronic device D2 and the location of the access point a, and the distance D3 between the location of the electronic device D3 and the location of the access point a, the server may determine the location of the electronic device D1, the location of the electronic device D2, and the location information of the electronic device D3 according to the location information of the electronic device D1, the location information of the electronic device D2, and the location information of the electronic device D3. Then, a circle is drawn by taking the position of each electronic device as a center of the circle and the distance between the position of each electronic device and the position of the access point as a radius, so that three circles can be determined. As can be seen from the figure, the intersection of the three circles is the position of the access point a. Therefore, the position of the access point a can be determined as long as the intersection of the three circles is determined.
In this embodiment of the application, after receiving information such as location information sent by a plurality of electronic devices, distances between the plurality of electronic devices and a plurality of access points, and identification information of the plurality of access points, the server may determine location information of the plurality of access points according to the information. Then, the server may associate the location information of each access point with the identification information of each access point, such as the MAC address of each access point, and store the associated information in the preset location information base. It can be known that, as time is accumulated, the position information of the access point stored in the preset position information base will be more and more.
It is understood that the greater the number of electronic devices that search for the same access point. The more electronic devices transmit information such as identification information of the same access point, a distance between the access point and the electronic device, and position information of the electronic device to the server. And determining the position information of the access point according to more position information of the electronic equipment and more distances between the access point and the electronic equipment enables the position information of the access point to be determined more accurately. Therefore, after the location information of an access point is determined, if the server receives the identification information of the access point, the distance between the access point and the new electronic device, and the location information of the new electronic device sent by the new electronic device to the server again, the server may determine the location information of the access point again.
In this embodiment of the application, after the electronic device is turned on for the first time, the electronic device may download the preset location information base from the server. Subsequently, the electronic device may delete the preset location information base at intervals of a preset time, and then download the preset location information base from the server, so that the preset location information base stored in the electronic device may be updated in real time. Or, after the server updates the preset location information base, the server may send an update message to the electronic device to prompt the electronic device that the preset location information base is updated. After receiving the update information, the electronic device may automatically delete the preset location information base in the electronic device, and re-download the updated preset location information base from the server.
In some embodiments, after receiving the update information, the electronic device may first determine whether the data size of the updated preset location information base is greater than a preset data size threshold. If the updated data volume of the preset location information base is greater than the preset data volume threshold, the electronic device may not delete the preset location information base in the electronic device. If the data volume of the updated preset position information base is less than or equal to the preset data volume threshold, the electronic device may automatically delete the preset position information base in the electronic device, and download the updated preset position information base from the server again. Wherein the preset data amount threshold may be determined by a user.
In other embodiments, after receiving the updated information, the electronic device may first detect the type of network to which the electronic device is currently connected. If the type of the currently connected network is a data network, such as a 3G network or a 4G network, the electronic device may obtain the traffic package from the operator to obtain the current remaining data volume of the traffic package. If the updated preset location information base has a data size greater than the remaining data size, the electronic device may not download the updated preset location information base. If the currently connected network type is a wireless network, such as WiFi or a hotspot, the electronic device may directly download the updated preset location information base, and update the preset location information base that already exists in the electronic device.
In some embodiments, the electronic device may obtain the updated preset location information base from the server. Then, the electronic device may compare the updated preset location information base with a preset location information base already existing in the electronic device. Then, the electronic device may obtain, from the updated preset location information base, the identification information of the access point and the location information corresponding to the identification information, which do not exist in the preset location information base existing in the electronic device, and store the identification information and the location information into the preset location information base existing in the electronic device, so as to update the preset location information base existing in the electronic device.
It is understood that the electronic device does not need to perform the process of downloading the preset location information base from the server each time before receiving the positioning request. Before receiving the positioning request, if the preset location information base does not exist in the electronic device, the electronic device downloads the preset location information base from the server. If the preset location information base exists in the electronic device, the electronic device may directly perform a process of searching for the access point according to the positioning request after performing the receiving of the positioning request, so as to determine the at least three searched access points.
For example, after determining the identification information of each access point, the electronic device may determine the location information of each access point according to the identification information of each access point and a preset location information base to obtain at least three location information, where the preset location information base includes the identification information of a plurality of access points and the location information corresponding to the identification information.
For example, assume that the electronic device determines the identification information for access point a1, the identification information for access point a2, and the identification information for access point A3. The electronic device may detect whether there is target identification information in the preset location information base that matches the identification information of the access point a 1. If target identification information matching the identification information of the access point a1 exists in the preset location information base, the electronic device may obtain location information associated with the target identification information from the preset location information base, and determine the location information as the location information of the access point a 1. Next, the electronic device may detect whether there is target identification information matching the identification information of the access point a2 in the preset location information base. If target identification information matching the identification information of the access point a2 exists in the preset location information base, the electronic device may obtain location information associated with the target identification information from the preset location information base, and determine the location information as the location information of the access point a 2. Finally, the electronic device may detect whether there is target identification information in the preset location information base that matches the identification information of access point a 3. If target identification information matching the identification information of the access point A3 exists in the preset location information base, the electronic device may obtain location information associated with the target identification information from the preset location information base, and determine the location information as the location information of the access point A3.
In some embodiments, assume that the electronic device determines the identification information for access point a1, the identification information for access point a2, and the identification information for access point A3. The electronic device may employ a first thread to detect whether there is target identification information in the preset location information base that matches the identification information of the access point a 1. If the target identification information matching with the identification information of the access point a1 exists in the preset location information base, the electronic device may acquire, by using a first thread, location information associated with the target identification information from the preset location information base, and determine the location information as the location information of the access point a 1. Meanwhile, the electronic device may detect whether target identification information matching the identification information of the access point a2 exists in the preset location information base using a second thread. If the target identification information matching with the identification information of the access point a2 exists in the preset location information base, the electronic device may use a second thread to obtain location information associated with the target identification information from the preset location information base, and determine the location information as the location information of the access point a 2. Meanwhile, the electronic device may detect whether target identification information matching the identification information of the access point a3 exists in the preset location information base by using the third thread. If the target identification information matching with the identification information of the access point A3 exists in the preset location information base, the electronic device may acquire, by using a third thread, location information associated with the target identification information from the preset location information base, and determine the location information as the location information of the access point A3. It can be known that the time for determining the location information can be saved by simultaneously determining the location information of the access point a1, the access point a2, and the access point A3 by using the first thread, the second thread, and the third thread.
205. The electronic device determines a signal strength of each access point.
206. The electronic equipment determines the distance between each access point and the electronic equipment according to the signal intensity of each access point and the preset corresponding relation between the signal intensity and the distance so as to obtain at least three distances.
For example, the electronic device may predetermine a preset correspondence between signal strength and distance. In order to ensure that the distance is more accurate. The preset corresponding relationship between the signal strength and the distance can be established according to the type of the access point, that is, different types of access points correspond to different preset corresponding relationships between the signal strength and the distance. For example, for an access point of type n1, a preset first correspondence of signal strength to distance may be established and associated with type n 1; for the access point of the type n2, a preset second corresponding relation between the signal strength and the distance can be established, and the preset second corresponding relation is associated with the type n 2; for an access point of type n3, a preset third correspondence of signal strength to distance may be established and associated with type n 3.
In some embodiments, different types of access points may also be combined to establish a preset correspondence relationship between the same signal strength and the same distance. For example, no matter which types of access points exist, the preset correspondence between the signal strength and the distance corresponding to the types of access points is the same.
In this embodiment, after determining the searched at least three access points, the electronic device may determine the signal strength of each access point. Then, the electronic device may determine the distance between each access point and the electronic device according to the signal strength of each access point and the preset corresponding relationship between the signal strength and the distance, so as to obtain at least three distances.
For example, assume that an access point of type n1 corresponds to a predetermined correspondence of signal strength to distance r1, an access point of type n2 corresponds to a predetermined correspondence of signal strength to distance r2, and an access point of type n3 corresponds to a predetermined correspondence of signal strength to distance r 3. After determining the at least three access points, the electronic device can determine a type of each access point, and a signal strength of each access point. For example, the at least three access points determined by the electronic device are an access point of type n1, an access point of type n2, and an access point of type n 3. Then, for an access point of type n1, the electronic device may determine the distance d1 between the access point of type n1 and the electronic device according to the signal strength of the access point of type n1 and the preset correspondence r1 between signal strength and distance. For an access point of type n2, the electronic device may determine the distance d2 between the access point of type n2 and the electronic device according to the signal strength of the access point of type n2 and the preset correspondence r2 between signal strength and distance. For an access point of type n3, the electronic device may determine the distance d3 between the access point of type n3 and the electronic device according to the signal strength of the access point of type n3 and the preset correspondence r3 between signal strength and distance.
It should be noted that the processes 203 and 205 can be executed simultaneously. Or the processes 203 and 204 may be executed first, and then the processes 205 and 206 may be executed; or flows 205 and 206 are performed first and then flows 203 and 204 are performed. And is not particularly limited herein.
207. The electronic equipment determines the position of the electronic equipment according to the at least three pieces of position information and the at least three distances.
For example, after determining the location information of the at least three access points, the electronic device may determine the location of the electronic device according to the location information of the at least three access points and the distances between the at least three access points and the electronic device.
The location information of the at least three access points may include locations, such as location coordinates, of the at least three access points.
As shown in fig. 4, after determining the location information of access point a1, the location information of access point a2, the location information of access point A3, the distance D4 between the location of access point a1 and the location of electronic device D, the distance D5 between the location of access point a2 and the location of electronic device D, and the distance D6 between the location of access point A3 and the location of electronic device D, the electronic device may determine the location of access point a1, the location of access point a2, and the location of access point A3 from the location information of access point a1, the location information of access point a2, and the location information of access point A3. Then, the electronic device may draw a circle with the position of each access point as a center and the distance between the position of each access point and the position of the electronic device as a radius, thereby determining three circles. As can be seen from the figure, the intersection of the three circles is the position of the electronic device D. Therefore, the position of the electronic device D can be determined as long as the intersection of the three circles is determined.
In some embodiments, before the flow 201, the following may be further included:
the electronic equipment detects whether the GPS signal intensity of the electronic equipment is less than or equal to a preset intensity threshold value;
if the GPS signal intensity of the electronic equipment is smaller than or equal to the preset intensity threshold value, the electronic equipment generates a positioning request.
For example, when the electronic device receives a positioning operation triggered by a user, the electronic device may detect whether a GPS signal strength of the electronic device is less than or equal to a preset strength threshold. If the GPS signal strength of the electronic device is less than or equal to the preset strength threshold, the electronic device may generate a positioning request and enter the process 201 of the embodiment of the present application. If the GPS signal intensity of the electronic device is greater than the preset intensity threshold, the electronic device may use the GPS for positioning. Wherein the preset intensity threshold may be determined by the electronic device. The predetermined intensity threshold may be an intensity value that enables the GPS to perform accurate positioning. That is to say, the electronic device can select to execute the positioning method of the embodiment of the present application, i.e. perform multipoint positioning or perform GPS positioning, according to the strength of the GPS signal strength. For example, when the GPS signal strength is strong (greater than a preset strength threshold), the electronic device may use GPS for positioning. When the GPS signal strength is weak (less than or equal to the preset strength threshold), the electronic device may generate a positioning request and proceed to the process 201 in the embodiment of the present application.
In some embodiments, if the GPS signal strength of the electronic device is greater than a preset strength threshold, the electronic device obtains a remaining power value of the electronic device;
the electronic equipment detects whether the residual electric quantity value is smaller than or equal to a preset electric quantity threshold value or not;
and if the residual electric quantity value is smaller than or equal to the preset electric quantity threshold value, the electronic equipment generates a positioning request.
The adoption of GPS for positioning requires a large amount of battery power to be consumed. Therefore, when the GPS signal strength of the electronic device is greater than the preset strength threshold, the electronic device may further obtain a remaining electric quantity value of the electronic device. If the remaining power value is less than or equal to the preset power threshold, that is, the remaining power is less, the electronic device may generate a positioning request to enter the process 201 of the embodiment of the present application. The preset electric quantity threshold value can be determined by the electronic device or a user. For example, the preset charge threshold may be a percentage value, such as 50%, 45%, etc.
Wherein, electronic equipment can be wearable equipment, like intelligent wrist-watch, intelligent bracelet, conversation wrist-watch or motion wrist-watch etc..
In some embodiments, because of limited watch antenna environments such as smart watches, smart bracelets, conversation watches, sports watches and the like, the GPS antenna efficiency generally cannot be increased, and therefore, for the smart watches, the smart bracelets, the conversation watches, the sports watches and the like, whether the GPS signal intensity is greater than a preset intensity threshold value or not, the positioning method of the embodiments of the present application can be directly adopted for positioning; or, except for a scene in which the GPS signal strength is relatively high (greater than a preset strength threshold), the positioning method of the embodiment of the present application may be used for positioning.
Because the precision that the smart mobile phone carries out GPS location is greatly higher than the precision that wearable equipment such as smart watch carries out GPS location. Therefore, in the establishment of the preset location information base, if the electronic device needs to perform GPS positioning to acquire the location information of the electronic device and upload the location information to the server, the server may only receive the location information uploaded by the smartphone to improve the accuracy of the location information.
