The present application provides a region determination method, an apparatus, an electronic device, and a computer-readable storage medium, which are intended to solve the above technical problems in the prior art.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
An embodiment of the present application provides a method for determining an area, and as shown in fig. 1, the method includes:
step S101: in the process of determining the area of the terminal, acquiring area information determined by a position sensor built in the terminal and area information determined by a WiFi signal of the terminal.
The terminal related to the embodiment of the present application includes any terminal having a positioning function and connecting to a wireless network hotspot, for example: the terminal is a mobile phone, a computer, a navigation device and the like.
The method comprises the steps that a position sensor arranged in a terminal comprises a GPS or Beidou positioning function, the step of obtaining area information determined by the position sensor arranged in the terminal comprises the step of determining a coordinate value of the terminal according to the GPS or Beidou positioning function arranged in the terminal, the coordinate value is the geographical position of the terminal, and the area information determined by the position sensor can be determined according to the geographical position of the terminal.
Specifically, the specific range of some places where the user frequently goes can be defined on the coordinate plane as the area information determined by the position sensor according to the history of the terminal user, and if the coordinate value of the terminal position cannot be determined according to the history of the terminal user, the place where the terminal is located can be determined according to the existing electronic map, and the range of the place in the information in the electronic map is determined as the area information determined by the position sensor.
It can be understood that the WiFi name connected to the terminal and the strength of the WiFi signal may be directly determined from the terminal, and the area information determined by the WiFi signal of the terminal specifically refers to a location where a device diverging the WiFi signal is located according to the WiFi name information connected to the terminal, and determines the location as the area information determined by the WiFi signal, where a stronger WiFi signal strength indicates that the location corresponding to the WiFi signal is more accurate. That is, the WIFI cannot directly provide the coordinate value of the terminal, but after the terminal is in communication connection with the WIFI device located at a certain location, the terminal is considered to be located at a certain location, and generally, the closer the terminal is to the fixed device located at a certain location, the stronger the signal is.
Step S102: if the area information determined by the position sensor is different from the area information determined by the WiFi signals, acquiring first target data and second target data of the terminal at a plurality of positions, wherein the first target data comprise the position information determined by the position sensor when the terminal is at each position, and the second target data comprise the WiFi signal strength of the terminal at each position.
It can be understood that, in an actual process, it is possible that the area information determined according to the position sensor and the area information determined according to the WiFi signal of the terminal are not consistent, that is, under the condition that the area information acquired according to the GPS and beidou positioning functions built in the terminal is not consistent with the area information determined according to the WiFi signal, an unexpected result will be caused by directly adopting a certain area information without further judgment, and at this time, it is necessary to determine more accurate area information from the two area information as the area where the terminal is located.
First target data and second target data of the terminal at a plurality of positions can be collected, wherein the first target data comprise position information determined by the terminal according to the position sensor when the terminal is at each position, and the second target data comprise WiFi signal strength of the terminal at each position.
Specifically, a coordinate value of the terminal at each position can be determined by using a GPS or beidou positioning function built in the terminal, and the coordinate value is position information of the terminal at the position; the WiFi name and the strength of the WiFi signal to which the terminal is connected at each location can then be determined directly from the terminal.
Through the position of the mobile terminal, the coordinates of the terminal at different positions and the signal intensity of WIFI are recorded, and multiple groups of target data can be acquired. Namely, when the terminal user moves, the position is judged to be changed, and then the coordinate of the current position and the signal intensity of the WIFI are recorded.
Step S103: the method comprises the steps of obtaining the number of first target data of position information in a first target area and the number of second target data of which WiFi signal strength meets a preset strength threshold, wherein the first target area comprises an area to which a preset position belongs when a terminal is at the preset position.
Step S104: and determining the area of the terminal from the area information determined by the position sensor and the area information determined by the WiFi signals according to the quantity of the first target data and the quantity of the second target data.
In this embodiment of the application, in the obtained plurality of first target data and second target data, the area where the terminal is located may be determined according to the number of the first target data in the first target area of the location information and the number of the second target data whose WiFi signal strength meets the predetermined strength threshold.
The first target area may be an area determined by position information of an initial position of the terminal at a predetermined position, such as an initial position of acquisition, when the terminal acquires the first target data and the second target data at a plurality of positions.
It is understood that when the number of the first target data of the position information of the terminal in the first target area is large, it indicates that it is appropriate to use the area information determined based on the position sensor as the area where the terminal is located; when the number of the second target data whose WiFi signal strength of the terminal satisfies the predetermined strength threshold is larger, it indicates that it is more appropriate to use the area information determined based on the WiFi signal as the area where the terminal is located.
In the method and the device for determining the area of the terminal, the area information determined by a position sensor and the area information determined by a WiFi signal of the terminal which are arranged in the terminal are obtained, when the area information determined by the position sensor and the area information determined by the WiFi signal of the terminal are different, first target data and second target data of the terminal at a plurality of positions are collected, the number of the first target data of the position information in the first target area and the number of the second target data of which the WiFi signal strength meets a preset strength threshold value are obtained, and finally the area where the terminal is located is determined from the area information determined by the position sensor and the area information determined by the WiFi signal according to the number of the first target data and the number of the second target data. The area where the terminal is located is determined more accurately through the embodiment of the application, and inconvenience brought to a user is avoided.
In an embodiment of the present application, the step S104 of determining, according to the quantity of the first target data and the quantity of the second target data, a location area of the terminal from the area information determined by the location sensor and the area information determined by the WiFi signal includes:
step S104 a: if the ratio of the number of first target data of the position information in a first target area to the total number of positions of a plurality of positions is not smaller than a first ratio threshold, and in second target data corresponding to the first target data based on the same position, the ratio of the number of third target data of which the WiFi signal strength is not larger than the first strength threshold to the number of second target data corresponding to the first target data based on the same position exceeds a second ratio threshold, determining the area information determined by the position sensor as the area where the terminal is located.
It can be understood that, in the embodiment of the present application, a specific determination method for determining an area where a terminal is located from area information determined by a location sensor and area information determined by a WiFi signal is provided.
For example, in the first target data at the plurality of positions, if the ratio of the number of the first target data with the position information in the first target area to the total number of the positions of the plurality of positions is not less than the first ratio threshold (e.g. 50%), wherein the first target area refers to an area determined by the built-in sensor according to the position information of the initial position of the terminal when the terminal is at the initial position, and in second target data corresponding to the first target data based on the same position, determining the area information determined by the position sensor as the area where the terminal is located if the ratio of the number of third target data with the WiFi signal strength not greater than a first strength threshold (for example, the strength is 0 or slightly greater than 0) to the number of second target data corresponding to the first target data based on the same position exceeds a second ratio threshold (for example, 40%).
In an embodiment of the present application, the step S104 of determining, according to the quantity of the first target data and the quantity of the second target data, a location area of the terminal from the area information determined by the location sensor and the area information determined by the WiFi signal includes:
step S104 b: if the ratio of the number of first target data of the position information in the first target area to the total number of positions of the plurality of positions is smaller than a first ratio threshold, and in second target data corresponding to the first target data which is based on the same position and is not in the first target area, the ratio of the number of fourth target data of which the WiFi signal strength is larger than the first strength threshold to the number of second target data corresponding to the first target data which is based on the same position and is not in the first target area exceeds a third ratio threshold, determining the area information determined by the WiFi signal as the area where the terminal is located.
It can be understood that, in the embodiment of the present application, a specific determination method for determining an area where a terminal is located from area information determined by a location sensor and area information determined by a WiFi signal is provided.
Specifically, for example, in the first target data at the plurality of positions, if a ratio of the number of the first target data having the position information in the first target area to the total number of the plurality of positions is smaller than a first ratio threshold (for example, 50%), and in the second target data corresponding to the first target data having the same position and not having the position information in the first target area, a ratio of the number of the fourth target data having the WiFi signal strength greater than the first strength threshold (for example, the strength is 0 or slightly greater than 0) to the number of the second target data corresponding to the first target data having the same position and not having the position information in the first target area exceeds a third ratio threshold (for example, 60%), the area information determined by the WiFi signal is used as the area where the terminal is located.
In an embodiment of the present application, the step S104 of determining, according to the quantity of the first target data and the quantity of the second target data, a location area of the terminal from the area information determined by the location sensor and the area information determined by the WiFi signal includes:
step S104 c: if the ratio of the number of the first target data of the position information in the first target area to the total number of the positions of the plurality of positions is smaller than the first ratio threshold, and in the second target data corresponding to the first target data whose position information is not within the first target area based on the same position, the ratio of the number of the fourth target data with the WiFi signal strength larger than the first strength threshold value to the number of the second target data corresponding to the first target data which is not in the first target area based on the same position and the position information is not larger than a third ratio threshold value, and in the first target data with the position information not in the first target area, the ratio of the number of the fifth target data with the position information in the second target area to the number of the first target data with the position information not in the first target area is not less than a fourth ratio threshold, and the area information determined by the position sensor is determined as the area where the terminal is located.
It can be understood that, in the embodiment of the present application, a specific determination method for determining an area where a terminal is located from area information determined by a position sensor and area information determined by a WiFi signal is provided.
Specifically, for example, in the first target data at the plurality of positions, if the ratio of the number of first target data having position information in the first target area to the total number of positions of the plurality of positions is smaller than a first ratio threshold (for example, 50%), and in the second target data corresponding to the first target data not having position information in the first target area based on the same position, the ratio of the number of fourth target data having WiFi signal strength greater than the first strength threshold (for example, having strength of 0 or slightly greater than 0) to the number of second target data corresponding to the first target data not having position information in the first target area based on the same position is not greater than a third ratio threshold (for example, 60%), and in the first target data not having position information in the first target area, the ratio of the number of fifth target data having position information in the second target area to the number of first target data having position information not in the first target area is not smaller than the third ratio threshold (for example, 60%) And (e.g., 60%) determining, by using the area information determined by the position sensor as the area of the terminal, a fourth ratio threshold, where the second target area is an area different from the first target area and is also a predetermined area.
In one embodiment of the present application, the region determining method further includes:
step S203: and acquiring sixth target data corresponding to the first target data in the first target area based on the same position and the position information.
Step S204: in the sixth target data, if the WiFi signal strength of the terminal conforms to the skewed distribution, determining the area information determined by the WiFi signal as the area where the terminal is located.
The principle of steps S201 to S202 is similar to that of steps S101 to S102, and is not described here again.
It can be understood that, if the terminal is located at the initial position, the WIFI signal strength of the first target data in the area determined according to the geographical position of the initial position of the terminal shows obvious skewed distribution, the area where the terminal is located takes the area information determined by the WIFI signal as the reference, otherwise, the probability that the obvious skewed distribution appears when the quality of the WIFI signal is good is high, taking the area information determined by the built-in sensor as the reference.
Wherein, the WiFi signal of terminal accords with the skewed distribution, includes:
and classifying the position points where the sixth target data are located based on the WiFi signal strength, wherein a convex set of a preset area of the position points corresponding to the sixth target data in each category meets a preset intersection condition.
And acquiring any point of the terminal in the first target area, wherein the distance from the point to the geometric center of each category of convex set and the WiFi signal strength corresponding to each category of convex set are expressed as strictly monotonically increasing or strictly monotonically decreasing functions.
For example, the location points where the sixth target data is located are classified into several categories according to the WiFi signal strength (where the number of categories may be determined according to the number of points, each category includes several points, for example, 3-6 points, allowing for duplicate points in the category).
After at most a set number of points are removed from each category (the number of points in a category is not more than 4, the set number is 1, the number of points in a category is 5-6, the set number is 2, and if the number of points in a category is more, the set number can be increased as appropriate), the convex set of the predetermined area of the position point corresponding to the sixth target data in each category may be a convex set including all the remaining points of each category and having the smallest area, and accordingly, the predetermined intersection condition includes that the convex sets of the categories having the smallest area of all the remaining points in each category do not intersect with each other or the area of the intersection portion is 0 (the area of the point and the line is 0).
When the terminal is located at the initial position, at least one point (called an origin for short) exists in the first target area or on the boundary, and the distance from the point to the geometric center of each category of convex set and the WiFi signal strength corresponding to each category of convex set are expressed as strictly monotonically increasing or strictly monotonically decreasing functions. A strictly monotonically increasing or strictly monotonically decreasing function means that the distance from the geometric center of the convex set with the largest WiFi signal strength to the origin is the smallest (or the largest), that the distance from the geometric center of the convex set with the second largest WiFi signal strength to the origin is the second smallest (or the second largest), and so on. The geometric center of the convex set, which may be defined as the point with the minimum sum of distances to all vertices of the convex set or other related definitions, must be located inside or on the boundary of the convex set based on the nature of the convex set. The convex set described above is consistent with the convex set concept commonly used in mathematics. The convex set may have a variety of definitions, for example, the set S is called a convex set if any two points in S are within the set S.
It can be understood that, if the WIFI signal strength of the sixth target data corresponding to the first target data of the location information in the first target area shows an obvious skewed distribution, it indicates that, along with the movement of the terminal, the WIFI signal strength may monotonically increase first, then monotonically decrease, or first monotonically decrease, then monotonically increase, and that the terminal is connected to the same WIFI hotspot, so that it is reasonable to determine the area information by using the WIFI signal in the area where the terminal is located at this time.
In one embodiment of the present application, the region determining method further includes:
step S305: and acquiring the functional interface corresponding to the area of the terminal according to the corresponding relation between the area identifier and the functional interface which is constructed in advance.
Step S306: and calling the functional interface to perform near field communication with the card swiping terminal with the function.
The principle of steps S301 to S304 is similar to that of steps S101 to S104, and is not described here again.
It can be understood that the terminal in this embodiment further has a function of NFC (Near Field Communication), and after acquiring accurate area information, the terminal may provide a corresponding card mode to complete the Near Field Communication with the card swiping terminal, where the card swiping terminal includes a bus card swiping terminal, a mall card swiping terminal, that is, a company card swiping terminal, and the like.
Specifically, the correspondence between the area identifier and the function interface can be pre-established in the terminal, and when accurate area information is determined, near field communication can be performed with the card swiping terminal with the function by calling the function interface with the area information.
For example, the terminal may determine scenes such as subway stations, shopping malls, units, and the like according to the determined area information, turn on the GPS or the WiFi while turning on the NFC by the terminal user, determine the scenes according to the determined area information, and then match various scenes. If finding out a corresponding scene, such as matching a subway station (bus station), the NFC calls a bus card mode function, and at the moment, the terminal can be equivalent to a bus card and can be used for swiping the bus card. The unit is matched to call the entrance guard card mode function, and the terminal can be equivalent to the fingerprint of the terminal user at the moment and is used for card swiping commuting in an entrance guard system.
In the method and the device for determining the area of the terminal, the area information determined by a position sensor and the area information determined by a WiFi signal of the terminal which are arranged in the terminal are obtained, when the area information determined by the position sensor and the area information determined by the WiFi signal of the terminal are different, first target data and second target data of the terminal at a plurality of positions are collected, the number of the first target data of the position information in the first target area and the number of the second target data of which the WiFi signal strength meets a preset strength threshold value are obtained, and finally the area of the terminal is determined from the area information determined by the position sensor and the area information determined by the WiFi signal according to the number of the first target data and the number of the second target data. And the terminal is matched to a corresponding card mode through an accurate area, so that the near field communication is completed, and the use experience of a terminal user is improved.
An embodiment of the present application provides an area determining apparatus, and as shown in fig. 4, the area determining apparatus 40 may include: a first acquisition module 401, an acquisition module 402, a second acquisition module 403, and a determination module 404, wherein,

The terminal related to the embodiment of the present application includes any terminal having a positioning function and connected to a wireless network hotspot, for example: the terminal is a mobile phone, a computer, a navigation device and the like.
The method comprises the steps that a position sensor arranged in a terminal comprises a GPS or Beidou positioning function, the step of obtaining area information determined by the position sensor arranged in the terminal comprises the step of determining a coordinate value of the terminal according to the GPS or Beidou positioning function arranged in the terminal, the coordinate value is the geographical position of the terminal, and the area information determined by the position sensor can be determined according to the geographical position of the terminal.
Specifically, the specific range of some places where the user frequently goes can be defined on the coordinate plane as the area information determined by the position sensor according to the history of the terminal user, and if the coordinate value of the terminal position cannot be determined according to the history of the terminal user, the place where the terminal is located can be determined according to the existing electronic map, and the range of the place in the information in the electronic map is determined as the area information determined by the position sensor.
It can be understood that the WiFi name connected to the terminal and the strength of the WiFi signal may be directly determined from the terminal, and the area information determined by the WiFi signal of the terminal specifically refers to a location where a device diverging the WiFi signal is located according to the WiFi name information connected to the terminal, and determines the location as the area information determined by the WiFi signal, where a stronger WiFi signal strength indicates that the location corresponding to the WiFi signal is more accurate.

It can be understood that, in an actual process, it is possible that the area information determined according to the position sensor and the area information determined according to the WiFi signal of the terminal are not consistent, that is, under the condition that the area information acquired according to the GPS and beidou positioning functions built in the terminal is not consistent with the area information determined according to the WiFi signal, an unexpected result will be caused by directly adopting a certain area information without further judgment, and at this time, it is necessary to determine more accurate area information from the two area information as the area where the terminal is located.
