Description

Multilayer fence construction method, cloud server and first terminal device

The present application claims priority of chinese patent application entitled "a method for constructing a multi-layered fence, a cloud server, and a first terminal device" filed by the national intellectual property office at 23/04 in 2021 under the application number 202110444566.3, the entire contents of which are incorporated herein by reference.

Technical Field

The application relates to the technical field of intelligent location services in the field of artificial intelligence, in particular to a multilayer fence construction method, a cloud server and a first terminal device.

Background

In a conventional ride mode, a passenger needs to resort to a ticket at the gate in order to pass through the gate. With the continuous development of terminal equipment and related technologies, passengers can get in the station after taking vehicles such as high-speed rails and subways by means of taking two-dimensional code gate-swiping machines. Therefore, a user can get in and take a bus by using the portable terminal equipment without purchasing an entity ticket, and the system is convenient and quick.

However, when a user needs to call the two-dimensional bus bar code on the terminal device, frequent operations (for example, entering a relevant application program from a main interface and then opening the two-dimensional bus bar code from an entrance of the relevant application program) are required, and user experience is poor. Therefore, a way of opening the bus two-dimensional code more intelligently and simply is needed to improve user experience.

Disclosure of Invention

The application provides a multilayer fence construction method, a cloud server and a first terminal device, which can construct a multilayer fence, so that the terminal device can realize accurate positioning of the terminal device according to the multilayer fence, and the requirement of a user on more accurate positioning is met. In some embodiments, when the terminal device determines that the current position is closer to the gate according to the multilayer fence constructed based on the position of the gate of the subway and the position of the subway station, the subway riding two-dimensional code can be automatically opened, tedious operations of a user on the terminal device are not needed, human-computer interaction efficiency and user experience can be improved, and the requirement that the user automatically opens the riding two-dimensional code when the terminal device is in a proper state (such as when the terminal device arrives near the gate) is met.

It should be noted that, in the present application, operations related to user data, such as data collection and data transmission to a server, and processing and use of the data, by a terminal device, are performed only when permission of a user is obtained.

In order to achieve the purpose, the technical scheme is as follows:

in a first aspect, the present application provides a multilayer fence construction method, which is applied to a cloud server, where the cloud server is in communication connection with a plurality of first terminal devices, and the method includes: receiving first dot data sent by a plurality of first terminal devices, wherein the first dot data comprise positioning information collected by each first terminal device in the plurality of first terminal devices in a preset area based on a first frequency; constructing N layers of fences with a first position as a center according to the first dot data, wherein N is more than or equal to 2, and the first position is located in a preset area; when the outermost fence of the N layers of fences is a 0 th fence, and the innermost fence is an N-1 th fence, the M-th fence corresponds to a plurality of positioning information, the plurality of positioning information includes positioning information acquired by each first terminal device at a first time corresponding to the first terminal device, the first time is a time when the first terminal device starts from the 0 th fence and time T1 elapses, T1= T M/N, where T is a time required for the first terminal device to start from the 0 th fence and reach the first position, and M is an integer greater than 0 and less than or equal to N-1.

In other implementation manners, only one layer of fence is provided, the fence corresponds to the position of the subway station, the geographic range corresponding to the position is large, and the two-dimensional code can be automatically popped up by the terminal device of the user as long as the user enters the range covered by the subway station, but the user actually needs to use the two-dimensional code when walking near the gate (generally, the user needs to walk for a long time to walk near the gate after entering the subway station), so that the two-dimensional code popping-up time is too early, interference on the use of the terminal device is caused by the user, the user can switch the two-dimensional code interface to a background if not using the two-dimensional code temporarily, and the user needs to operate the terminal device to switch the two-dimensional code interface to a foreground when needing to be used, and the operation is time-consuming.

According to some embodiments provided by the application, after the cloud server constructs the multi-layer fence, the terminal device can compare the collected positioning information with the positioning information corresponding to each layer of fence, so that the fence where the terminal device is currently located (for example, the terminal device is located at the mth layer of fence or a position between the mth layer of fence and the M-1 layer of fence) is determined, and accurate positioning of the terminal device is achieved. Therefore, the terminal equipment can automatically open the two-dimensional code when the user is close to the gate (for example, the user determines that the terminal equipment is located in the innermost fence, and the innermost fence corresponds to the position of the gate) (at the time when the user needs to use the two-dimensional code), so that the effect of bringing convenience to the user to take transportation means (for example, boarding, taking a ship, getting on a subway, getting on a cable car and the like) is achieved, and the user experience is improved. Some embodiments that this application provided for terminal equipment can demonstrate the two-dimensional code automatically at more suitable opportunity, can not demonstrate the two-dimensional code too early, reduces the interference to user's unnecessary, promotes user and terminal equipment interactive efficiency and experience.

In one possible implementation, constructing N-level fences centered about a first location from first dot data includes: screening from the first dot data to obtain a plurality of positioning information corresponding to the M-th layer fence, wherein the plurality of positioning information correspond to a plurality of geographic coordinates; generating an M-tier fence from the plurality of geographic coordinates.

As can be seen, each layer of fence can correspond to a plurality of positioning information and a plurality of geographic coordinates (a plurality of positioning information corresponds to a plurality of geographic coordinates). Therefore, the terminal equipment can judge which fence the terminal equipment is in by acquiring the positioning information and/or the geographic coordinates of the terminal equipment, and accurate positioning of the terminal equipment is realized.

In one possible implementation, the method further comprises: and determining a first position according to positioning information acquired when the plurality of first terminal devices generate the target event.

It can be seen that a first terminal device may be considered to arrive at a first location (e.g., a gate location) when the first terminal device generates a target event. The cloud server can obtain a more accurate gate position by performing big data analysis on the first positions corresponding to the first terminal devices.

In one possible implementation, the target event includes a subway code swiping event, an airport code swiping event, a train station code swiping event, a dock code swiping event, or a cable car code swiping event.

Therefore, when the multi-layer fence construction method is applied to different scenes, the types of the target events can be different. For example, when a multi-level fence centered on an airport needs to be constructed, the target event is an airport code swiping event; when a multi-layer fence taking a subway station as a center needs to be constructed, the target event is a subway code swiping event; when a multi-layer fence taking a railway station as a center needs to be constructed, a target event is a code brushing event of the railway station; when a multi-layer fence taking a wharf as a center needs to be constructed, the target event is a wharf code brushing event; when a multi-layer fence taking a cable car waiting area as a center needs to be constructed, the target event is a cable car code brushing event. By analogy, when a multi-layer fence of other areas needs to be constructed, the target event can also be a corresponding other event.

In a possible implementation manner, the cloud server is further communicatively connected to the second terminal device, and the method further includes: receiving second dotting data sent by second terminal equipment, wherein the second dotting data comprise positioning information collected by the second terminal equipment in a preset area based on a second frequency; screening from the second dotting data to obtain first positioning information corresponding to the M-th fence, wherein the first positioning information comprises positioning information acquired by the second terminal device at a second moment, the second moment is the moment when the second terminal device starts from the 0-th fence and the time T2 elapses, and T2= T2M/N, wherein T2 is the time required by the second terminal device to start from the 0-th fence and reach the first position; and adding the first positioning information into a plurality of positioning information corresponding to the M-th layer of fence.

Therefore, after the multilayer fence is constructed, the cloud server can further enrich a plurality of positioning information corresponding to each layer of fence according to the positioning information of the second terminal device (which can be the same device as the first terminal device or can not be the same device as the first terminal device), so that the multilayer fence is more accurate, and the positioning result obtained by the terminal device by utilizing the multilayer fence is more accurate.

In one possible implementation, the method further includes: and adding the geographic coordinates corresponding to the first positioning information into a plurality of geographic coordinates corresponding to the M-th layer of fence.

Therefore, in the process of updating the fences, a plurality of positioning signals corresponding to each layer of fence can be enriched, and a plurality of geographic coordinates corresponding to each layer of fence can be enriched. In this manner, the geographic extent of the multi-tiered fence can be made more accurate.

In a possible implementation manner, if the first positioning information further corresponds to an X-th fence in the N-th fences, the method further includes: determining a first frequency of using the first positioning information as positioning information corresponding to the X-th layer fence, and determining a second frequency of using the first positioning information as positioning information corresponding to the M-th layer fence; x is an integer which is greater than 0 and less than or equal to N-1 and is not equal to M; if the first times is greater than the second times, determining that the first positioning information is positioning information corresponding to the X-th layer fence; and if the first times is less than or equal to the second times, determining the first positioning information and the positioning information corresponding to the M-th layer of fence.

As can be understood, since the user is not necessarily in a uniform motion state, the time for the second terminal device to acquire the first positioning information for multiple times may not be the same, so that the fences corresponding to the first positioning information may also be different. Therefore, the first time and the second time of the first positioning information are respectively determined, and the fence corresponding to the first positioning information is determined according to the judgment results of the first time and the second time, so that the problem of position conflict caused by the fact that the same positioning information corresponds to multiple layers of fences can be avoided.

In one possible implementation, the preset area includes a subway station, an airport, a railway station, a dock, or a cable car waiting area.

It can be seen that the preset area can be different when constructing the multi-layer fence with different scenes. Namely, the multilayer fence construction method provided by the embodiment of the application has the advantages of wide application range and strong adaptability.

In one possible implementation, the first location includes a location of a gate located within a subway station, an airport, a railway station, a dock, or a cable waiting area.

That is, the first position corresponds to the preset region. For example, if the preset area is a subway station, the first position may be a position where a gate in the subway station is located; if the predetermined area is a train station, the first location may be a location of a gate in the train station.

In one possible implementation, the positioning information includes different types of positioning signals and corresponding strengths of the positioning signals.

Understandably, according to the signal transmission principle, the signal strength is weakened along with the increase of the propagation distance in the spatial propagation process, and the closer the receiving end device is to the signal source, the stronger the received signal strength is; the farther the receiving end device is from the signal source, the weaker the received signal strength. In addition, the relationship between the signal strength and the propagation distance of different types of positioning signals is also different. Thus, the geographical coordinates of the first terminal device may be determined by determining the type of positioning signal and its strength.

In one possible implementation, the positioning information includes one or more of a global positioning system signal, a cell identifier, a bluetooth low energy signal, a wireless network signal, and a near field communication signal.

The positioning accuracy is different in the positioning process by utilizing different types of signals. For example, when the first terminal device performs positioning by using signals of a global positioning system, a cell identifier, a bluetooth low energy signal, and a wireless network signal, respectively, to obtain a geographic coordinate, the accuracy of the obtained geographic coordinate is sequentially reduced. In this way, the terminal device may select one or more of a global positioning system signal, a cell identifier, a bluetooth low energy signal, a wireless network signal, and a near field communication signal to determine the geographic coordinates according to actual conditions (e.g., whether the terminal device is located on the ground or underground, and whether a wireless network or a bluetooth device is installed) in the preset area, which is more accurate.

In a second aspect, the application provides a method for constructing a multi-layer fence, which is applied to a cloud server, wherein the cloud server is in communication connection with a first terminal device, and the method includes: receiving first dot data sent by first terminal equipment, wherein the first dot data comprise positioning information collected by the first terminal equipment in a preset area based on first frequency; constructing N layers of fences taking the first position as the center according to the first dot data, wherein N is more than or equal to 2, and the first position is located in a preset area; when the outermost fence of the N layers of fences is a 0 th fence and the innermost fence is an N-1 th fence, the M-th fence corresponds to a plurality of positioning information, the plurality of positioning information includes positioning information acquired by the first terminal device at a first time, the first time is a time when the first terminal device starts from the 0 th fence and time T1 elapses, T1= T × M/N, where T is a time required for the first terminal device to start from the 0 th fence and reach the first position, and M is an integer greater than 0 and less than or equal to N-1.

As can be seen, the cloud server may also construct a multi-layer fence adapted to one terminal device (e.g., the first terminal device) according to the positioning information collected by the terminal device. So, the multilayer rail that finally obtains more possesses individual adaptability, and this terminal equipment utilizes the location result that multilayer rail obtained also more accurate to make terminal equipment can further accurate self and the distance between the floodgate machine, reach the effect of opening the two-dimensional code in good time, convenience of customers takes the vehicle, promotes user experience.

In one possible implementation, constructing N-level fences centered about a first location from first dot data includes: screening from the first dot data to obtain a plurality of positioning information corresponding to the M-th layer of fence, wherein the plurality of positioning information correspond to a plurality of geographic coordinates; generating an M-tier fence from the plurality of geographic coordinates.

As can be seen, each layer of fence can correspond to multiple positioning information and multiple geographic coordinates (multiple positioning information corresponds to multiple geographic coordinates). Therefore, the terminal equipment can judge which fence the terminal equipment is in by acquiring the positioning information and/or the geographic coordinates of the terminal equipment, and accurate positioning of the terminal equipment is realized.

In one possible implementation, the method further includes: and determining a first position according to positioning information acquired when the first terminal equipment generates the target event.

It will be appreciated that a first terminal device may be deemed to arrive at a first location (e.g., a gate location) when the first terminal device generates a target event. And the user can carry the first terminal equipment to pass through the first position for multiple times, and the target event is generated once after each time of passing. Therefore, the cloud server can perform data analysis on the positioning information acquired by the first terminal device when the first terminal device generates the target event every time and determine the first position, and the obtained result is more accurate.

Therefore, when the multi-layer fence construction method is applied to different scenes, the types of the target events can be different. For example, when a multi-layer fence of an airport needs to be constructed, the target event is an airport code swiping event; when a multi-layer fence of a subway station needs to be constructed, the target event is a subway code swiping event; when a multi-layer fence of a railway station needs to be constructed, the target event is a code brushing event of the railway station; when a multi-layer fence of the wharf needs to be constructed, the target event is a wharf code brushing event; when a multilayer fence of a cable car waiting area needs to be constructed, the target event is a cable car code brushing event. By analogy, when a multi-layer fence of other areas needs to be constructed, the target event can also be a corresponding other event.

In one possible implementation, the method further comprises: receiving second dotting data sent by the first terminal equipment, wherein the second dotting data comprise positioning information acquired by the first terminal equipment in a preset area based on a second frequency; screening from the second dotting data to obtain first positioning information corresponding to the M-th fence, wherein the first positioning information comprises positioning information acquired by the first terminal device at a second moment, the second moment is the moment when the first terminal device starts from the 0-th fence and the time T2 elapses, and T2= T2M/N, wherein T2 is the time required by the first terminal device to start from the 0-th fence and reach the first position; and adding the first positioning information into a plurality of positioning information corresponding to the M-th layer of fence.

The second frequency may be the same as or different from the first frequency. In a word, after the cloud server constructs the multilayer fence according to the positioning information acquired by the first terminal device, the first terminal device can continue to acquire the positioning information, so that a plurality of positioning information corresponding to each layer of fence is enriched, the multilayer fence is more accurate, and the positioning result obtained by the terminal device by utilizing the multilayer fence is more accurate.

As can be understood, since the user is not necessarily in a uniform motion state, times for the second terminal device to acquire the first positioning information multiple times may be different, and thus fences corresponding to the first positioning information may also be different. Therefore, the first times and the second times of the first positioning information are respectively determined, and the fence corresponding to the first positioning information is determined according to the judgment results of the first times and the second times, so that the problem of position conflict caused by the fact that the same positioning information corresponds to multiple layers of fences can be avoided.

Therefore, when constructing the multi-layer fence with different scenes, the preset areas can be different. Namely, the multilayer fence construction method provided by the embodiment of the application is wide in application range and high in adaptability.

That is, the first position corresponds to the preset area. For example, if the preset area is a subway station, the first position may be a position where a gate in the subway station is located; if the predetermined area is a train station, the first location may be a location of a gate in the train station.

It can be understood that, according to the signal transmission principle, the signal strength decreases with the increase of the propagation distance in the spatial propagation process, and the closer the receiving end device is to the signal source, the stronger the received signal strength; the further the receiving end device is from the signal source, the weaker the received signal strength. In addition, the relationship between the signal strength and the propagation distance of different types of positioning signals is also different. Thus, the geographical coordinates of the first terminal device may be determined by determining the type of positioning signal and its strength.

In one possible implementation, the positioning signal includes one or more of a global positioning system signal, a cell identifier, a bluetooth low energy signal, a wireless network signal, and a near field communication signal.

The positioning accuracy is different in the positioning process by utilizing different types of signals. For example, when the first terminal device performs positioning by using signals of a global positioning system, a cell identifier, a bluetooth low energy signal, and a wireless network signal, respectively, to obtain a geographic coordinate, the accuracy of the obtained geographic coordinate is sequentially reduced. In this way, the terminal device can select one or more of global positioning system signals, cell identifiers, bluetooth low energy consumption signals, wireless network signals and near field communication signals to determine the geographic coordinates according to the actual conditions (for example, whether the terminal device is located on the ground or underground, whether a wireless network or a bluetooth device is installed, and the like) in the preset area, and the geographic coordinates are determined more accurately.

In a third aspect, the application provides a multilayer fence constructing method, which is applied to a first terminal device, wherein the first terminal device is in communication connection with a cloud server, and the method includes: collecting first dot data in a preset area based on a first frequency, wherein the first dot data comprise positioning information collected by a first terminal device in the preset area based on the first frequency; sending first dot data to a cloud server so that the cloud server constructs N layers of fences with a first position as a center according to the first dot data, wherein N is more than or equal to 2, and the first position is located in a preset area; when the outermost fence of the N layers of fences is a 0 th fence, and the innermost fence is an N-1 th fence, the M-th fence corresponds to a plurality of positioning information, the plurality of positioning information includes positioning information acquired by each first terminal device at a first time corresponding to the first terminal device, the first time is a time when the first terminal device starts from the 0 th fence and time T1 elapses, T1= T M/N, where T is a time required for the first terminal device to start from the 0 th fence and reach the first position, and M is an integer greater than 0 and less than or equal to N-1.

Therefore, the first terminal device can collect the positioning information and send the positioning information to the cloud server, so that the cloud server constructs an N-layer fence with the first position as the center according to the first dot data. Therefore, after the cloud server constructs the multiple layers of fences, the terminal device can compare the collected positioning information with the positioning information corresponding to each layer of fence, so that the fence where the terminal device is located is determined (for example, the terminal device is located at the M-th layer of fence or a position between the M-th layer of fence and the M-1-th layer of fence), and accurate positioning of the terminal device is achieved. In addition, the terminal equipment can automatically open the two-dimensional code when the user is close to the gate (for example, the user is determined to be located at the innermost fence), so that the effect that the user conveniently takes a vehicle (for example, boarding, taking a ship, getting on a subway, getting on a cable car and the like) is achieved, and the user experience is improved.

Therefore, when the multilayer fence with different scenes is constructed, the preset areas can be different. Namely, the multilayer fence construction method provided by the embodiment of the application has the advantages of wide application range and strong adaptability.

In one possible implementation, the first location comprises a location of a gate located within a subway station, an airport, a train station, a dock, or a cable waiting area.

In a possible implementation manner, the positioning signal includes one or more of a global positioning system signal, a cell identifier, a bluetooth low energy signal, a wireless network signal, and a near field communication signal.

Because the positioning accuracy is different in the process of positioning by using different types of signals. For example, when the first terminal device performs positioning by using signals of a global positioning system, a cell identifier, a bluetooth low energy signal, and a wireless network signal, respectively, to obtain a geographic coordinate, the accuracy of the obtained geographic coordinate is sequentially reduced. In this way, the terminal device can select one or more of global positioning system signals, cell identifiers, bluetooth low energy consumption signals, wireless network signals and near field communication signals to determine the geographic coordinates according to the actual conditions (for example, whether the terminal device is located on the ground or underground, whether a wireless network or a bluetooth device is installed, and the like) in the preset area, and the geographic coordinates are determined more accurately.

In a fourth aspect, the present application provides a method for constructing a multi-layer fence, which is applied to a first terminal device, and includes: collecting first dot data in a preset area based on a first frequency; the first dot data comprises positioning information which is acquired by the first terminal equipment in a preset area based on a first frequency; constructing N layers of fences taking the first position as the center according to the first dot data, wherein N is more than or equal to 2, and the first position is located in a preset area; when the outermost fence of the N layers of fences is a 0 th fence and the innermost fence is an N-1 th fence, the M-th fence corresponds to first positioning information, the first positioning information includes positioning information acquired by the first terminal device at a first time, the first time is a time when the first terminal device starts from the 0 th fence and time T1 elapses, T1= T × M/N, where T is time required for the first terminal device to start from the 0 th fence and reach the first position, and M is an integer greater than 0 and less than or equal to N-1.

Therefore, the first terminal equipment can directly construct the multilayer fence adaptive to the first terminal equipment according to the acquired positioning information after acquiring the positioning information, and the multilayer fence has individual adaptability and can protect the privacy of users. So, this terminal equipment utilizes the location result that multilayer rail obtained also more accurate to make terminal equipment can further accurate self and the distance between the floodgate machine, reach the effect of opening the two-dimensional code in good time, convenience of customers takes the vehicle, promotes user experience.

In one possible implementation, constructing N-level fences centered at a first location from the first dot data includes: screening from the first dot data to obtain a plurality of positioning information corresponding to the M-th layer fence, wherein the plurality of positioning information correspond to a plurality of geographic coordinates; generating an M-tier fence from the plurality of geographic coordinates.

It is to be appreciated that the first terminal device may be considered to arrive at a first location (e.g., gate location) when the first terminal device generates the target event. And the user can carry the first terminal equipment to pass through the first position for multiple times, and the target event is generated once after each time of passing. Therefore, the cloud server can perform data analysis on the positioning information acquired by the first terminal equipment when the first terminal equipment generates the target event every time and determine the first position, and the obtained result is more accurate.

In one possible implementation, the method further comprises: acquiring second dotting data in the preset area based on a second frequency, wherein the second dotting data comprise positioning information acquired by the first terminal equipment in the preset area based on the second frequency; screening from the second dotting data to obtain first positioning information corresponding to the M-th fence, wherein the first positioning information comprises positioning information acquired by the first terminal device at a second moment, the second moment is the moment when the first terminal device starts from the 0-th fence and the time T2 elapses, and T2= T2M/N, wherein T2 is the time required by the first terminal device to start from the 0-th fence and reach the first position; and adding the first positioning information into a plurality of positioning information corresponding to the M-th layer fence.

Therefore, in the process of updating the fences, not only can a plurality of positioning signals corresponding to each layer of fence be enriched, but also a plurality of geographic coordinates corresponding to each layer of fence can be enriched. In this manner, the geographic extent of the multi-tiered fence can be made more accurate.

In a possible implementation manner, if the first positioning information further corresponds to an X-th fence in the N-th fences, the method further includes: determining a first frequency of using the first positioning information as positioning information corresponding to the X-th layer fence, and determining a second frequency of using the first positioning information as positioning information corresponding to the M-th layer fence; x is an integer which is greater than 0 and less than or equal to N-1 and is not equal to M; if the first times are larger than the second times, determining that the first positioning information is positioning information corresponding to the X-th layer fence; and if the first times is less than or equal to the second times, determining the first positioning information and the positioning information corresponding to the M-th layer fence.

As can be understood, since the user is not necessarily in a uniform motion state, times for the second terminal device to acquire the first positioning information multiple times may be different, and thus fences corresponding to the first positioning information may also be different. Therefore, the first time and the second time of the first positioning information are respectively determined, and the fence corresponding to the first positioning information is determined according to the judgment results of the first time and the second time, so that the problem of position conflict caused by the fact that the same positioning information corresponds to multiple layers of fences can be avoided.

That is, the first position corresponds to the preset area. For example, if the preset area is a subway station, the first position may be a position where a gate in the subway station is located; if the predetermined area is a train station, the first position may be a position of a gate in the train station.

In a possible design, when the terminal reaches the security inspection door, the NFC signal can be detected, at the moment, the terminal can estimate the time of reaching the gate from the security inspection door, and then the riding two-dimensional code is popped up in time for a user to ride by swiping a code.

In another possible design, the terminal may automatically pop up the ride two-dimensional code upon detecting that its holder is approaching the gate. However, this method cannot accurately know when the passenger approaches the gate, so that the pop-up timing of the riding two-dimensional code is not accurate. For example, when the actual distance between the subway entrance and the gate (i.e., the actual walking distance of the user) is determined to be L and the preset time is T, only when the moving speed of the user is L/T (m/s), it can be ensured that the user really needs to pass through the gate when the two-dimensional bus bar code is automatically popped up, otherwise, no matter whether the moving speed of the user is greater than L/T (m/s) or the moving speed of the user is less than L/T (m/s), the timing of popping up the two-dimensional bus bar code by the terminal device is inaccurate, and the user experience is affected.

In the mode, the terminal equipment cannot accurately judge when the user passes through the gate, so that the time for popping up the riding two-dimensional code by the terminal equipment is not accurate, and the user is influenced to get on the station.

The embodiment of the application provides a method for constructing a multi-layer fence, which is applied to a cloud server. The cloud server may construct an N-tier fence centered around a first location (e.g., a gate location) from the first dot data sent by the plurality of first terminal devices. The first dot data comprises positioning information which is acquired by each first terminal device in a plurality of first terminal devices in a preset area based on a first frequency; when the outermost fence of the N layers of fences is a 0 th fence and the innermost fence is an N-1 th fence, the mth layer of fence corresponds to multiple pieces of positioning information, the multiple pieces of positioning information include positioning information acquired by each first terminal device at a first time corresponding to the first terminal device, the first time is a time when the first terminal device starts from the 0 th fence and after time T1 elapses, T1= T M/N, where T is a time required for the first terminal device to start from the 0 th fence and reach a first position, and M is an integer greater than 0 and less than or equal to N-1.

Therefore, the terminal equipment can realize accurate positioning of the terminal equipment according to the built multilayer fence, when the terminal equipment is determined to be close to the gate (for example, the terminal equipment is determined to be located in the innermost fence), the two-dimensional code is automatically opened, the effect that a user conveniently takes transportation means (for example, boarding, taking a ship, getting on a subway, getting on a cable car and the like) is achieved, and user experience is improved.

The embodiment of the application provides a method for constructing a multilayer fence, which is applied to the cloud server 100 in fig. 1. Please refer to fig. 4, which is a flowchart of a method for constructing a multi-layered fence according to an embodiment of the present disclosure. The multilayer fence construction method comprises the following steps:

s101, receiving first dot data sent by a plurality of first terminal devices.

The first dot data comprises positioning information collected by each first terminal device in a preset area based on a first frequency. It should be noted that the first terminal device may be any one of the terminal devices 200 in fig. 1.

The preset area may be predetermined by the cloud server. The preset area may be different according to different actual application environments. For example, the preset area may include an area such as a subway station, an airport, a train station, a dock, or a cable waiting area. In consideration of the fact that public places such as subway stations and airports have large floor areas, the range of the preset area can be further reduced. For example, the preset area may be an area surrounded by a gate at a certain entrance of a subway station, a waiting area at a certain gate at an airport, an area surrounded by a security inspection door at a railway station to a ticket gate, or an area that can include a user movement track in other places (such as a dock and a cable car waiting area), which is not limited specifically herein.

It can be understood that, taking the preset area as the area from a certain entrance of the subway station to the gate for surrounding as an example, the position of the certain entrance can be considered as the outermost fence of the preset area. Thus, when the first terminal device detects that the user enters the outermost fence, the user can be considered to enter the subway station. In other words, the predetermined area may be an area surrounded by the outermost fence; therefore, the cloud server can establish the outermost fence and determine the preset area according to the outermost fence.

In an alternative embodiment, the cloud server may establish the outermost fence by extending a predetermined distance around the fence based on the first location (e.g., gate location), thereby determining the predetermined area. For example, as shown in fig. 5, the cloud server may use the gate 201 as a center and extend the same distance to the periphery to obtain the outermost fence 202. The cloud server can determine the first position according to positioning information collected when the plurality of first terminal devices generate the target event. It can be seen that the first terminal device may be considered to arrive at the first location when the first terminal device generates the target event. For example, the first location may be a location of a gate located in a subway station, an airport, a railway station, a dock, or a cable waiting area. The target event may refer to a code swiping event, and the code swiping event may be an event that a user scans a riding two-dimensional code displayed on the first terminal device by using a code scanning window of the gate to turn on the gate, or another event that is performed by using the first terminal device to turn on the gate, which is not particularly limited herein. For example, the target event may include a subway code swipe event, an airport code swipe event, a train station code swipe event, a dock code swipe event, or a cable car code swipe event. Taking the user taking a subway as an example, the user holds the terminal equipment to take the subway, when the user arrives at the gate, the two-dimensional code needs to be presented to the gate, and the gate is opened after scanning the code for the user to pass. At the moment, the terminal equipment can upload the collected positioning information, and the cloud server determines the position of the gate according to the positioning information collected by the plurality of terminal equipment when the code swiping event is detected.

In another alternative embodiment, as shown in fig. 6, the cloud server may also use the gate 201 as a center, and build the outermost fence 202 by extending irregularly around according to the actual terrain of the subway station (train station, airport, dock, cable waiting area, etc.). Or, the cloud server may also directly construct the outermost fence according to the actual terrain of the subway station (such as a train station, an airport, a wharf, a cable car waiting area, and the like).

After the cloud server determines the preset area, the first terminal device may determine whether to enter the preset area by acquiring a Global Positioning System (GPS) signal and/or a CELL identity (CELL ID) (e.g., a CELL ID of a room division base station of a subway station) signal. It is understood that when the first terminal device detects the entry into the outermost fence, the first terminal device can be considered to enter the preset area. Therefore, the first terminal device can determine whether the first terminal device is located in the preset area by judging whether the first terminal device enters the outermost fence.

Next, how to determine whether the first terminal device is located in the preset area will be described by taking the preset area as an example of an area where a subway station is located. In an optional implementation manner, the first terminal device may monitor a GPS signal in real time, determine a real-time location of the first terminal device through the GPS signal, and determine that the first terminal device enters the outermost fence (the preset area) when the real-time location is determined to be within the range of the subway station. Or, the first terminal device may obtain the CELL ID in real time, and determine the real-time location of the first terminal device through the CELL ID, so that when the real-time location of the first terminal device is determined to be within the range of the subway station, the first terminal device is determined to enter the outermost fence (the preset area). Or, the first terminal device may acquire the GPS signal and the CELL ID in real time, and determine that the first terminal device enters the outermost fence (the preset area) when the real-time positions indicated by the GPS signal and the CELL ID are within the range of the subway station. Therefore, the accuracy of the detection result can be improved, and the misjudgment can be reduced.

In another alternative embodiment, the first terminal device may determine whether the outermost fence is located on the ground or underground according to the information of the position of the outermost fence, the terrain of the subway station, the floor area and the like. If the outermost fence is located on the ground, the first terminal device can determine whether to enter the outermost fence according to the GPS signal and the CELL ID; considering that the GPS is not accurately located underground, the first terminal device may determine whether to enter the outermost fence according to the CELL ID when determining that the outermost fence is located underground. So, through considering that outermost rail is located the condition on ground or underground, first terminal equipment can utilize different signals to judge whether get into outermost rail, avoids the inaccurate problem in location that the signal inaccurate leads to, improves the accuracy of judged result, reduces the possibility of erroneous judgement.

When the first terminal equipment detects that the first terminal equipment enters a preset area (outermost fence), the first terminal equipment collects positioning information, and continuously collects the positioning information according to a first frequency from the moment of collecting the positioning information until the first terminal equipment detects a target event. When the first terminal device detects the target event, the first terminal device can acquire the positioning information for the last time.

The first frequency may be understood as a time interval between the first terminal device and the first terminal device collecting the positioning information. For example, the first frequency of the first terminal device may be 2 seconds/time, and the process of the first terminal device acquiring the positioning information may be: the method comprises the steps of collecting positioning information once when the condition that the first terminal device enters a pre-constructed outermost fence is detected, and then collecting the positioning information once again at intervals of 2s until a target event is detected, wherein the first terminal device collects the positioning information for the last time. For another example, the first frequency of the first terminal device may be 5 seconds/time, and the process of the first terminal device acquiring the positioning information includes: when the situation that the mobile terminal enters the pre-constructed outermost fence is detected, the positioning information is collected once, and then the positioning information is collected again at intervals of 5s until the target is detected, and the first terminal equipment collects the positioning information for the last time. It should be noted that the first frequencies of different first terminal devices may be the same or different, and are not limited herein.

The positioning information may be used to indicate the type and strength of the positioning signal. Therefore, the geographic coordinates of the first terminal device when the first terminal device collects the positioning information can be determined according to the positioning information. Optionally, the positioning signal may include one or more of GPS, CELL ID, bluetooth Low Energy (BLE), basic Service Set Identifier (BSSID), near Field Communication (NFC), and the like. In this manner, the first terminal device may determine the geographic coordinates of the first terminal device from one or more of the collected GPS, CELL ID, BLE, BSSID, NFC, etc. signals.

Illustratively, a wireless Access Point (AP) may be disposed within the subway station, and the AP may be configured to generate a wireless network signal. Therefore, the first terminal device can detect the wireless network signal and determine the signal strength of the wireless network signal after entering the subway station. The first terminal device may further determine a BSSID of the AP device according to the detected public wireless network, where the BSSID is a Media Access Control (MAC) address of the AP device. The signal strength of the wireless network signal is weakened along with the increase of the propagation distance in the space propagation process, and the closer the receiving end equipment is to the signal source, the stronger the received signal strength is; the further the receiving end device is from the signal source, the weaker the received signal strength. In this way, the first terminal device may determine a signal source according to the BSSID, estimate a distance between the first terminal device and the signal source (AP device) according to the signal strength of the detected wireless network signal and a known positioning model, and then estimate geographical coordinates of the first terminal device according to the estimated distance between the first terminal device and the AP devices.

Further alternatively, a plurality of positioning tags (for example, beacons) may be provided in advance in the subway station. When the first terminal device enters the signal coverage of the positioning tag, the broadcast signal of the positioning tag can be detected. Therefore, the first terminal device can also calculate the geographic coordinate of the first terminal device according to the broadcast signal and a preset positioning algorithm.

When the first terminal device performs positioning based on the four signal pairs of GPS, CELL ID, BLE, and BSSID, the accuracy of the geographic coordinates obtained based on BLE, BSSID, CELL ID, and GPS signals is sequentially reduced. In this way, the first terminal device may select one or more of NFC, BLE, BSSID, CELL ID, GPS signals according to actual requirements to determine the geographic coordinates of the first terminal device, which is more accurate.

In an alternative embodiment, the types of the positioning information collected by the first terminal device each time may not be consistent. For example, as shown in table 1: the first terminal device enters the outermost fence at 09; the first terminal device collects the positioning information for the second time after 5 seconds of collecting the positioning information for the first time, namely at 09; the first terminal device collects the positioning information for the third time after 5 seconds of collecting the positioning information for the second time, namely at 09; the first terminal device collects the positioning information for the fourth time after 5 seconds of collecting the positioning information for the third time, namely at 09.

TABLE 1

Dotting sequence number	Time of dotting	Type of signal
			1	09:22:50	GPS、CELL ID
2	09:22:55	CELL ID
			3	09:23:00	CELL ID、BLE、BSSID
4	09:23:05	CELL ID、BSSID、NFC
			……	……	……
10	09:23:35	BLE、BSSID

In general, when the first terminal device collects positioning information several times, it may be considered that the user has just entered the subway station and is far away from the gate, and a signal with relatively low positioning accuracy (such as a GPS) may be used to position the first terminal device. As the number of times of acquiring the positioning information by the first terminal device increases, it may be considered that the user is closer to the gate, and the requirement for the positioning accuracy of the first terminal device is higher, so that the positioning may be performed by using signals (e.g., BLE, BSSID) with relatively high positioning accuracy. Therefore, the positioning signals of different types are acquired according to the distance between the first terminal device and the gate, the positioning requirement of the first terminal device can be met, and the problem that the power consumption of the first terminal device is large due to the fact that all types of positioning signals are acquired for a long time can be solved.

It can be understood that each first terminal device may collect the positioning information in the above manner, and upload the positioning information to the cloud server. It should be noted that the first terminal device may upload the acquired positioning information in real time, that is, when the first terminal device acquires the positioning information, the first terminal device immediately uploads the positioning information to the cloud server. The first terminal device may also upload all positioning information collected in one dotting process to the server together after detecting the target event. The dotting process starts when the first terminal device detects that the first terminal device enters the outermost fence, and ends when the first terminal device detects the target event.

S102, constructing N layers of fences with the first position as the center according to the first dot data, wherein N is more than or equal to 2, and the first position is located in a preset area.

When the outermost fence of the N layers of fences is the 0 th fence and the innermost fence is the (N-1) th fence, the M-th fence corresponds to a plurality of positioning information. The plurality of positioning information includes positioning information acquired by each first terminal device at a first time corresponding to the first terminal device. The first time is the time when the first terminal device starts from the 0 th fence and the time T1 elapses, T1= T × M/N, where T is the time required for the first terminal device to start from the 0 th fence and reach the first position, and M is an integer greater than 0 and less than or equal to N-1.

Please refer to fig. 7, which is a flowchart illustrating the step S102. The S102 includes:

and S1021, screening a plurality of positioning information corresponding to the M-th layer of fence from the first dot data, wherein the plurality of positioning information correspond to a plurality of geographic coordinates.

It can be understood that each layer of fence in the N layers of fences corresponds to a plurality of positioning information, and the plurality of positioning information corresponding to different layers of fences are different. In addition, each first terminal device may correspond to a plurality of first time instants, the plurality of first time instants corresponding to the multi-layer fence. In this way, the cloud server may classify a plurality of positioning information included in the first dotting data to form a dotting record of each first terminal device, and then determine a plurality of first moments corresponding to the first terminal device according to each dotting record.

For example, the first dot data may further include an identifier of each first terminal device, and each positioning information corresponds to one identifier. The cloud server may classify a plurality of positioning information included in the first dotting data based on the identifier, so as to obtain a dotting record of each first terminal device. The dotting record may include the positioning information collected by the first terminal device and the time when the positioning information was collected. Therefore, the cloud server can determine a plurality of corresponding first moments according to the dotting record of each first terminal device, and determine a plurality of positioning information corresponding to each layer of fence by combining each first moment.

It should be noted that, in order to ensure the accuracy of the screening result, before the cloud server screens the multiple positioning information corresponding to the mth-layer fence, the cloud server may perform operations such as discretization and smoothing on the positioning information included in the first dot data. For example, the cloud server determines that a dotting process includes positioning information acquired at the time T1 and positioning information acquired at the time T3, but the cloud server should also include positioning information acquired at the time T2 according to normal logic of the first terminal device for acquiring the positioning information; the time T1, the time T2, and the time T3 are three adjacent times. At this time, the cloud server may infer the positioning information at the time T2 according to the positioning information acquired at the time T1 and the positioning information acquired at the time T3, and add the positioning information at the time T2 inferred to the plurality of positioning information included in the dotting process. For another example, the cloud server determines that positioning information acquired at times T1, T2, and T3 is included in one dotting process (where the times T1, T2, and T3 are three adjacent times), but the positioning information at the time T2 is greatly different from the positioning information at the times T1 and T3, the cloud server may determine that the positioning information at the time T2 is abnormal, perform a smoothing operation on the positioning information at the time T2 according to the positioning information at the times T1 and T3, and replace the original positioning information at the time T2 with the positioning information obtained by the smoothing operation.

Illustratively, the dotting record of the terminal device 1 can be shown in table 2, the terminal device 1 detects entering the outermost fence (the 0 th fence) and collects the positioning information 1 at the time of 18. It can be seen that 30 seconds are required for the terminal device 1 to arrive at the first position starting from the fence at level 0. Assuming that N =5, since the positioning information corresponding to the layer 0 fence should be the positioning information acquired when the terminal device 1 enters the layer 0 fence (i.e., 18. The positioning information corresponding to the fence on the layer 1 should be positioning information acquired after 1/5 × 30=6 seconds from the end of the terminal device 1 in the following section of 18; therefore, the cloud server may determine location information 2 as location information corresponding to the layer 1 fence. The positioning information corresponding to the 2 nd fence is the positioning information acquired by the terminal device 1 after 2/5 × 30=12 seconds from the start of 18; therefore, the cloud server may determine the location information 3 as location information corresponding to the layer 2 fence. The positioning information corresponding to the fence at the 3 rd floor should be positioning information acquired by the terminal device 1 after 3/5 × 30=18 seconds from the position of 18; therefore, the cloud server may determine location information 4 as location information corresponding to the layer 3 fence. The positioning information corresponding to the fence on the 4 th floor should be the positioning information acquired by the terminal device 1 after 4/5 × 30=24 seconds from the position of the terminal device 22; therefore, the cloud server may determine the location information 5 as location information corresponding to the layer 4 fence.

For another example, as shown in table 3, the dotting record of the terminal device 2 is that the terminal device 2 detects entering the outermost fence and collects the positioning information a at 08; further, the terminal device 2 detects the target event and collects the positioning information E at 08. It can be seen that it takes 24 seconds for the terminal device 2 to arrive at the first position starting from the tier 0 fence. Assuming that N =4, since the positioning information corresponding to the fence at the layer 0 should be the positioning information acquired when the terminal device 2 enters the fence at the layer 0 (i.e. 08; the positioning information corresponding to the 1 st fence is the positioning information acquired by the terminal device 2 after 1/4 × 24=6 seconds from the 08; the positioning information corresponding to the fence on the 2 nd floor should be positioning information acquired after 2/4 × 24=12 seconds from 08; the positioning information corresponding to the fence at the 3 rd floor should be positioning information acquired by the terminal device 2 after 3/4 × 24=18 seconds from 08. In this way, the cloud server may determine the positioning information a as positioning information corresponding to the fence at layer 0, and use the positioning information D as positioning information corresponding to the fence at layer 3.

And S1022, generating M layers of fences according to the multiple geographic coordinates.

For example, as shown in fig. 8 (a), the plurality of positioning information corresponding to the mth-layer fence respectively correspond to the geographic coordinates A1, B1, C1, D1, E1, and F1, and then the mth-layer fence 503 shown in fig. 8 (B) may be generated according to the geographic coordinates A1, B1, C1, D1, E1, and F1. By analogy, each of the N layers of fences can be generated. In fig. 8, 501 can be understood as the innermost fence and 502 can be understood as the outermost fence.

It will be appreciated that the greater the number of geographic coordinates, the more accurate the M-layer fence will be generated.

In an optional implementation manner, after the cloud server constructs the N-layer fence, the cloud server may send the related data of the N-layer fence to the plurality of first terminal devices. Therefore, each first terminal device can judge the fence where the first terminal device is located according to the collected positioning information and the constructed N layers of fences. For example, the first terminal device may collect the positioning information every 5 seconds after detecting the entry into the outermost fence. The first terminal device may compare the acquired positioning information with a plurality of positioning information corresponding to each layer of fence every time the first terminal device acquires the positioning information, so as to determine the fence in which the first terminal device is located (for example, the first terminal device may be located in the mth layer of fence, or between the mth layer of fence and the M-1 layer of fence). When the first terminal device detects that it is approaching the innermost fence (e.g., just reaching the innermost fence, or about to reach the innermost fence, or already within the innermost), the ride two-dimensional code is popped up.

For another example, after detecting that the mobile terminal enters the outermost fence, the first terminal device may collect the positioning information every 5 seconds, collect the positioning information every time, and determine the geographic coordinate corresponding to the positioning information. In addition, the first terminal device may compare the geographic coordinate with multiple geographic coordinates corresponding to each layer of fence, so as to determine a fence in which the first terminal device is located (for example, the first terminal device may be located in an mth layer of fence, or between the mth layer of fence and an M-1 layer of fence). When the first terminal device detects that it is approaching the innermost fence (e.g., just reaching the innermost fence, or is about to reach the innermost fence, or is already located within the innermost), the ride two-dimensional code is popped up.

Therefore, the multilayer fence can accurately position the terminal equipment by constructing the multilayer fence. Therefore, the terminal equipment can automatically open the two-dimensional code when the user is close to the gate, the effect that the user can conveniently take the vehicle is achieved, and the user experience is improved.

In an optional implementation manner, after the N-layer fence is constructed by the cloud server, the related data of the N-layer fence may also be sent to the second terminal device, and the N-layer fence is updated according to the second dotting data uploaded by the second terminal device. Referring to fig. 9, the method for constructing a multi-layered fence provided by the present application further includes:

and S103, receiving second dotting data sent by the second terminal equipment.

The second dotting data comprise positioning information collected by the second terminal device in the preset area based on the second frequency. It should be noted that the second terminal device may be one of the plurality of first terminal devices, or may be another terminal device different from the first terminal device. The second frequency may be the same as the first frequency or different from the first frequency, and is not limited herein.

In addition, a process of the second terminal device acquiring the positioning information in the preset area based on the second frequency is substantially similar to a process and a principle of the first terminal device acquiring the positioning information in the preset area based on the first frequency, and for details, reference is made to the foregoing contents, which are not repeated herein.

And S104, screening the second dotting data to obtain first positioning information corresponding to the fence of the M layer.

And the first positioning information comprises positioning information acquired by the second terminal equipment at the second moment. The second time is the time after the second terminal device starts from the fence of the 0 th floor and the time t2 elapses. Where T2= T2 × M/N, T2 is the time required for the second terminal device to arrive at the first location from the 0 th fence.

And S105, adding the first positioning information into a plurality of positioning information corresponding to the M-th layer fence.

In an optional implementation manner, the cloud server may further add the geographic coordinate corresponding to the first positioning information to the multiple geographic coordinates corresponding to the mth-layer fence. So, after establishing the multilayer rail, the cloud server can also continue to enrich a plurality of locating information that every layer of rail corresponds according to second terminal equipment's locating information, can make the multilayer rail more accurate to terminal equipment utilizes the positioning result that the multilayer rail obtained also more accurate.

As can be understood, since the user is not necessarily in a uniform motion state, the time for the second terminal device to acquire the first positioning information for multiple times may not be the same, so that the fences corresponding to the first positioning information may also be different.

In an optional implementation manner, if the first positioning information further corresponds to an X-th fence in the N-th fences, the cloud server may further determine a first number of times that the first positioning information is used as positioning information corresponding to the X-th fence, and determine a second number of times that the first positioning information is used as positioning information corresponding to the M-th fence; x is an integer which is greater than 0 and less than or equal to N-1 and is not equal to M; if the first times are larger than the second times, determining that the first positioning information is positioning information corresponding to the X-th layer fence; and if the first times is less than or equal to the second times, determining the first positioning information and the positioning information corresponding to the M-th layer fence. Therefore, the problem of conflict caused by the fact that the same positioning information corresponds to the multilayer fence can be avoided.

Wherein the first time number satisfies the formula:

wherein, count _X Is the first order, y _X And i is the frequency of the first positioning information serving as the positioning information corresponding to the X-th layer fence on the ith day, pi is the preset weight corresponding to the ith day, Y is the preset effective number of days, and i is more than or equal to 1 and less than or equal to Y.

The second number satisfies the formula:

wherein, count _M Is a second order, y _M i is the number of times that the first positioning information is taken as the positioning information corresponding to the M-th layer of fence on the ith day, pi is the preset weight corresponding to the ith day, Y is the preset effective number of days, and i is more than or equal to 1 and is less than or equal to Y.

In the above two equations, pi is smaller as i is larger. That is, the first frequency and the second frequency of the first positioning information can be finally obtained by counting the times of the first positioning information respectively serving as the positioning information corresponding to the X-th layer fence and the times of the first positioning information serving as the positioning information corresponding to the M-th layer fence within the 1 st to Y-th days of the day, and combining the preset weights of each day.

It should be further noted that other terminal devices may also acquire the first positioning information. That is, when the first number and the second number are counted, the condition of the first positioning information acquired by other terminal devices can be counted.

For example, the cloud server receives the first positioning information 4 times in the same day (3.31 days), wherein the cloud server takes the first positioning information as positioning information corresponding to the mth-layer fence 3 times and takes the first positioning information as positioning information corresponding to the xth-layer fence 1 time; the cloud server receives the first positioning information 5 times in the previous day (3.30 days), wherein the cloud server takes the first positioning information as positioning information corresponding to the mth-layer fence 2 times, takes the first positioning information as positioning information corresponding to the xth-layer fence 3 times, and p1=0.9 and p2=0.8.

Thus, the first time =1 × p1+3 × p2=3.3 of the first positioning information; the second time =3 × p1+2 × p2=4.3 of the first positioning information, and then since the first time is less than the second time, the cloud server finally uses the first positioning information as the positioning information corresponding to the mth layer of fence.

Therefore, the first time and the second time of the first positioning information are respectively determined, and the fence corresponding to the first positioning information is determined according to the judgment results of the first time and the second time, so that the problem of position conflict caused by the fact that the same positioning information corresponds to multiple layers of fences can be avoided.

Wherein T1= T × M/N, T is the time required for the first terminal device to arrive at the first position from the 0 th fence. M is an integer greater than 0 and less than or equal to N-1.

As can be seen, the cloud server may also construct a multi-layer fence adapted to one terminal device (e.g., the first terminal device) according to only the positioning information collected by the terminal device. So, the multilayer rail that finally obtains more possesses individual adaptability, and the positioning result that this terminal equipment utilized multilayer rail to obtain is also more accurate to make terminal equipment can further accurate self and the distance between the floodgate machine, reach the effect of opening the two-dimensional code in good time, convenience of customers takes the vehicle, promotes user experience.

It should be noted that the first terminal device may also display the prompt box 1202 on another interface (e.g., a screen lock interface or an interface corresponding to an application).
