Description

Electronic fence data acquisition method and electronic equipment

Technical Field

The application relates to the technical field of electronics, in particular to an electronic fence data acquisition method and electronic equipment.

Background

The electronic device (for example, a mobile phone) can collect wireless scanning data of the wireless access point and send the wireless scanning data to the server, and the server is used for generating an electronic fence of the wireless access point and sending information of the electronic fence to the electronic device.

In order to reduce power consumption, the electronic device is limited in the number of times of acquiring wireless scanning data of the wireless access points every day, so that after the electronic device is connected to one wireless access point and continuously acquires the wireless scanning data of the wireless access point, the electronic device reaches the upper limit of the acquisition number of times, cannot acquire the wireless scanning data of other wireless access points, and the server cannot generate electronic fences of other wireless access points.

Disclosure of Invention

The embodiment of the application provides an electronic fence data acquisition method and electronic equipment, which are used for uniformly acquiring wireless scanning data of wireless access points so that a server can generate electronic fences of the wireless access points.

In order to achieve the above purpose, the embodiment of the present application adopts the following technical scheme:

In a first aspect, an electronic fence data collection method is provided, including: determining an initial value of the residual acquisition times of the wireless scanning data of the target wireless access point according to the updated state of the electronic fence of the target wireless access point; if the residual acquisition times in the period is greater than zero, scanning the target wireless access point to acquire wireless scanning data, and sending the wireless scanning data to a server, wherein the wireless scanning data is used for updating the electronic fence by the server; and updating the residual acquisition times.

According to the electronic fence data acquisition method provided by the embodiment of the application, the electronic equipment maintains one residual acquisition frequency for each wireless access point instead of only maintaining the total frequency for acquiring the wireless scanning data of all the wireless access points. If the residual acquisition times are greater than zero, the electronic equipment scans the target wireless access point to acquire wireless scanning data, and sends the wireless scanning data to a server for updating the electronic fence by the server; and the electronic equipment updates the residual acquisition times after acquiring the wireless scanning data each time. When the remaining times of the wireless scanning data of one wireless access point collected by the electronic equipment is zero, the remaining collection times can be used for collecting the wireless scanning data of other wireless access points, so that the wireless scanning data of each wireless access point can be collected in an equalizing mode, and the server can generate the electronic fence of each wireless access point.

In one possible implementation, determining the initial value of the remaining acquisition times according to the updated state of the electronic fence of the target wireless access point includes: if the electronic fence is updated, determining an initial value of the residual acquisition times according to the time difference between the last updating time and the current time of the electronic fence.

This embodiment discloses that when the electronic fence has been updated, if the initial value of the remaining number of acquisitions is determined from the last update time of the electronic fence.

In one possible embodiment, the larger the time difference, the larger the initial value of the number of remaining acquisitions; the smaller the time difference, the smaller the initial value of the number of remaining acquisitions.

The reason is that: if the last update time of the electronic fence corresponding to the identifier of the target wireless access point is closer to the current time, the electronic fence is more updated, the possibility of updating the electronic fence again is smaller, and the electronic fence is not required to be updated again by the aid of so much wireless scanning data, and the electronic fence is limited by a collection time threshold, so that more collection times can be reserved for updating the electronic fences corresponding to the identifiers of other wireless access points; if the last update time of the electronic fence corresponding to the identification of the target wireless access point is farther from the current time, which indicates that the information of the electronic fence is older, the more likely the electronic fence is updated again, more wireless scan data may be required to update the electronic fence again.

In one possible implementation, determining an initial value of a remaining acquisition number of wireless scan data of the target wireless access point according to an update status of an electronic fence of the target wireless access point includes: if the electronic fence is not updated, determining that the initial value of the residual acquisition times is a value smaller than or equal to an acquisition times threshold, wherein the acquisition times threshold refers to the maximum times of acquiring wireless scanning data of all wireless access points in the period. In particular, the initial value of the number of remaining acquisitions may be directly equal to the threshold number of acquisitions.

That is, when the electronic fence is not updated, more wireless scanning data of the target wireless access point is collected as much as possible so as to send the wireless scanning data to the server to generate the electronic fence as soon as possible.

In one possible embodiment, the method further comprises: if the wireless scan data has been sent to the server for a plurality of consecutive periods, but the electronic fence has not been updated, then in one acquisition, the target wireless access point is scanned a plurality of consecutive times to acquire a plurality of wireless scan data, and the plurality of wireless scan data is sent to the server.

That is, the electronic device only reduces the remaining number of times of acquiring the wireless scan data of the target wireless access point once, and also only increases the total number of times of acquiring the wireless scan data of all wireless access points once in the present period.

The purpose is that: at the cost of power consumption, more wireless scanning data of the target wireless access point are acquired as much as possible in one acquisition, so that the problem that the wireless scanning data of the target wireless access point cannot still be generated for a long time is solved, the generation of the electronic fence of the target wireless access point is quickened, the total times of acquiring the wireless scanning data of all wireless access points in the period is not obviously increased, and more acquisition times are reserved for acquiring the wireless scanning data of other wireless access points.

In one possible implementation, the remaining collection times and the updated status of the electronic fence are indexed by the identity of the target wireless access point, the method further comprising: and if the acquisition triggering condition is met, acquiring the identification of the target wireless access point.

In one possible embodiment, satisfying the acquisition triggering condition includes: the total number of times of collecting the wireless scanning data of all the wireless access points in the period is smaller than a collection time threshold, wherein the collection time threshold refers to the maximum number of times of collecting the wireless scanning data of all the wireless access points in the period.

In order to reduce the power consumption of the electronic device, the total number of times the electronic device collects wireless scanning data of the wireless access point in a single period is limited, i.e. limited by the collection time threshold.

In one possible embodiment, satisfying the acquisition triggering condition further includes: the wireless access point is connected to the target wireless access point for a certain time or the wireless scanning data is acquired from last time in the period for a certain time.

The electronic equipment is connected to the target wireless access point for a certain time, and the purpose is that the electronic equipment can stably collect wireless scanning data of the target wireless access point. The electronic equipment can collect the wireless scanning data of the target wireless access point for a plurality of times in the period so as to update the electronic fence of the target wireless access point more quickly.

In a second aspect, there is provided an electronic device comprising a processor and a memory in which instructions are stored which, when executed by the processor, perform a method as described in the first aspect and any of its embodiments.

In a third aspect, there is provided a computer readable storage medium comprising instructions which, when run on an electronic device, cause the electronic device to perform the method of the first aspect and any implementation thereof.

The communication system shown in fig. 1 operates as follows: the electronic device 101 may scan the BSSID, signal strength, etc. of the wireless access point 102 to obtain wireless scan data (e.g., wi-Fi scan data), and may record an event of disconnection of the wireless communication connection to obtain wireless disconnection data (e.g., wi-Fi scan data), and send the wireless scan data and/or the wireless disconnection data to the server 104 through the base station 103 and/or the wireless access point 102. The server 104 performs model training according to the wireless scanning data and/or the wireless disconnection data collected over a period of time (for example, 14 days) to obtain an electronic fence, and sends the electronic fence to the electronic device 101 through the base station 103 and/or the wireless access point 102.

The electronic fence according to the present application is to create a virtual geographic boundary within a certain area by using the characteristics of a wireless access point (such as Wi-Fi device) within the area (such as basic service set identifier information (BSSID), signal strength, etc.). By way of example, the area may be an elevator hall, a floor, a bus stop, a store, a restaurant, etc.

When an electronic device enters or leaves the electronic fence, the electronic device may trigger certain functions to reduce network jamming. For example, when an electronic device enters the electronic fence, it switches from mobile communication to wireless communication (e.g., wi-Fi communication), or from mobile communication to mobile communication overlay wireless communication (e.g., using full network convergence acceleration (Link Turbo) technology). When the electronic device leaves the electronic fence, switching from wireless communication to mobile communication, or switching from mobile communication to mobile communication in addition to wireless communication, etc. The wireless access point may be a wireless access point that the electronic device scans for or connects to within the area.

For Link Turbo technology, for example, the upper limit of the electronic device 101 to collect wireless scan data every day is 9, and the triggering condition is that the electronic device 101 is connected to the wireless access point 102 for more than 10 minutes. The upper limit of the wireless disconnection data collected by the electronic device 101 every day is 9, and the triggering condition is that after the electronic device 101 is connected to the wireless access point 102, the signal intensity is weakened until the wireless network is disconnected, for example, the mobile phone is connected to the Wi-Fi device in a bright screen state, and as the mobile phone is far away from the Wi-Fi device, the Wi-Fi signal intensity is weakened until the Wi-Fi connection is disconnected, and the electronic device 101 collects the wireless disconnection data.

At present, the training of the electronic fence mainly has the following problems:

On the one hand, the wireless scanning data and the wireless disconnection data of a large number of wireless access points are transmitted to the server and used for generating the electronic fence of each wireless access point, the data volume of some wireless access points is large so that the corresponding electronic fence is sufficiently trained, and the data volume of some wireless access points is small so that the corresponding electronic fence is insufficiently trained, namely the problem that the electronic fence training degrees of different wireless access points are different exists.

In part, the triggering condition of the electronic device for collecting the wireless scanning data of the wireless access points is easy to achieve, but in order to reduce the power consumption, the frequency of the electronic device for collecting the wireless scanning data of the wireless access points every day is limited, so that the electronic device can easily reach the upper limit of the collection frequency after being connected to one wireless access point and continuously collecting the wireless scanning data of the wireless access points, the wireless scanning data of other wireless access points can not be collected any more, and the server can not generate the electronic fence of the other wireless access points.

On the other hand, due to the limitation of the complexity of the electronic fence training algorithm, a large amount of data of the wireless access points are transmitted to the server, but are not all used for electronic fence training, and some data of the wireless access points are over-sampled, for example, when the data amount of the single wireless access point in the last 14 days exceeds 300, the server only adopts the last 300 data to generate the electronic fence, other data are not fully utilized, and therefore, not only additional storage resources of the server are occupied, but also transmission resources are occupied during data uploading.

As shown in fig. 4, according to the electronic fence data acquisition method and the electronic device provided by the embodiment of the application, according to the update state of the electronic fence of the wireless access point, the acquisition of the wireless scanning data of the wireless access point is interfered. In one aspect, data collection of recently updated electronic pens is suppressed, reserving more sampling opportunities for recently non-updated electronic pens. On the other hand, the over-sampling of wireless scanning data of a single wireless access point is avoided, the waste of storage resources of a server is reduced, and the consumption of transmission resources is reduced.

As shown in fig. 5, the electronic fence data collection method provided by the embodiment of the application includes:

s101, if the acquisition triggering condition is met, the electronic equipment acquires the identification of the target wireless access point.

The meeting of the acquisition triggering condition refers to meeting of the triggering condition of the electronic equipment for acquiring the wireless scanning data of the target wireless access point, and the meeting of the acquisition triggering condition at least comprises: in this period, the total number of times the electronic device collects wireless scan data for all wireless access points (e.g., wi-Fi devices) is less than a collection time threshold, which is, for example, 9. The acquisition frequency threshold refers to the maximum frequency of acquiring wireless scanning data of all wireless access points in the period.

The reason is that: in order to reduce the power consumption of the electronic device, the total number of times the electronic device collects wireless scanning data of the wireless access point in a single period is limited, i.e. limited by a collection time threshold, which may be, for example, 9. The period of the present application may be 12 hours, 24 hours (i.e., one day), one week, etc., and is not particularly limited, and the present application is exemplified by one day, but is not limited thereto.

Optionally, meeting the acquisition triggering condition may further include: the electronic device is connected to the target wireless access point for a certain time (e.g., 10 minutes), for a certain time (e.g., 10 minutes) since the last time the electronic device acquired wireless scan data of the target wireless access point in the present period, etc. The electronic equipment is connected to the target wireless access point for a certain time, and the purpose is that the electronic equipment can stably collect wireless scanning data of the target wireless access point. The electronic equipment can collect the wireless scanning data of the target wireless access point for a plurality of times in the period so as to update the electronic fence of the target wireless access point more quickly.

The wireless scan data of each wireless access point includes information such as the identity of the wireless access point (e.g., BSSID), signal strength, etc. The wireless access points broadcast the identifiers of the wireless access points on the broadcast channel, and the electronic equipment can acquire the identifiers of the wireless access points from the broadcast channel when scanning signals of the wireless access points. The electronic device can directly measure the signal strength of the wireless access points when scanning the signals of the wireless access points, and the signal strength is influenced by factors such as the transmitting power, the measuring distance, the obstacle and the like of the wireless access points.

S102, the electronic equipment determines the initial value of the residual acquisition times of the wireless scanning data of the target wireless access point according to the updated state of the electronic fence of the target wireless access point.

Also, in order to reduce the power consumption of the electronic device, the number of times the electronic device collects wireless scanning data of a certain wireless access point in a single period is limited, and the initial value of the remaining collection times is smaller than or equal to the collection times threshold.

The electronic device may construct an electronic fence database in the form of an electronic fingerprint (finger print) (e.g., a lightweight data exchange format (JavaScript object notation, JSON) based on javascript), as shown in table 1, in which information of corresponding electronic fences is stored for different wireless access points, including: the identification of the wireless access point, the update time of the electronic fence and the residual acquisition times of the wireless scanning data of the wireless access point. That is, the remaining number of acquisitions of the wireless scan data of the wireless access point and the updated status of the electronic fence of the wireless access point are indexed by the identity of the target wireless access point.

TABLE 1

In the initial state of the period, the remaining acquisition times of the wireless scanning data of the wireless access point are in an invalid state, for example, the remaining acquisition times are invalid values larger than an acquisition times threshold, or the remaining acquisition times do not exist. The electronic device determines only an initial value of the remaining number of acquisitions once in one cycle, at which time the remaining number of acquisitions becomes a valid value (a value less than or equal to the threshold number of acquisitions).

Therefore, if the remaining collection times in the present period are in an invalid state, which indicates that the electronic device is in the initial state of the present period, the electronic device is required to determine the initial value of the remaining collection times. If the residual acquisition times are in an effective state in the period, and the residual acquisition times are greater than zero and less than or equal to an acquisition times threshold, the electronic equipment scans the target wireless access point to acquire wireless scanning data of the target wireless access point and sends the wireless scanning data to the server. If the remaining collection times in the period are in an effective state and the remaining collection times are equal to zero, the upper limit of the collection times is reached, and the process is ended.

The following describes how the electronic device targets the updated state of the electronic fence of the wireless access point, and determines the initial value of the remaining acquisition times.

The electronic device may query the server as to whether the electronic fence has been updated (or is present), or from a locally stored electronic fence database.

In one possible implementation, if the electronic fence has been updated, the electronic device may determine the initial value of the remaining number of acquisitions based on a time difference between a last update time of the electronic fence and a current time. It should be noted that, for a newly generated electronic fence, the last update time of the electronic fence refers to the generation time of the electronic fence.

The basic principle followed by the above embodiments is: if the time difference is larger, the initial value of the residual acquisition times is larger; the smaller the above-mentioned time difference is, the smaller the initial value of the remaining number of acquisitions is.

The reason why the above embodiment follows the basic principle described above is that: if the last update time of the electronic fence corresponding to the identifier of the target wireless access point is closer to the current time, the electronic fence is more updated, the possibility of updating the electronic fence again is smaller, and the electronic fence is not required to be updated again by the aid of so much wireless scanning data, and the electronic fence is limited by a collection time threshold, so that more collection times can be reserved for updating the electronic fences corresponding to the identifiers of other wireless access points; if the last update time of the electronic fence corresponding to the identification of the target wireless access point is farther from the current time, which indicates that the information of the electronic fence is older, the more likely the electronic fence is updated again, more wireless scan data may be required to update the electronic fence again.

For example, assuming that the threshold number of acquisitions is 9 and the time difference between the last update time and the current time of the electronic fence is Δt _bssid, the initial value n _bssid of the remaining acquisitions can be obtained by the following piecewise function:

In another possible implementation, if the electronic fence is not updated, the electronic device may determine an initial value of the remaining number of acquisitions based on a threshold number of acquisitions. For example, the initial value of the number of remaining acquisitions may take a value less than or equal to the threshold number of acquisitions, in particular the initial value of the number of remaining acquisitions may be directly equal to the threshold number of acquisitions. That is, when the electronic fence is not updated, more wireless scanning data of the target wireless access point is collected as much as possible so as to send the wireless scanning data to the server to generate the electronic fence as soon as possible.

And S103, if the residual acquisition times of the wireless scanning data of the target wireless access point in the period are greater than zero, the electronic equipment scans the target wireless access point to acquire the wireless scanning data of the target wireless access point and sends the wireless scanning data to the server. Otherwise, the flow is ended.

The step enables the server to update the electronic fence corresponding to the identification according to the wireless scanning data of the target wireless access point.

S104, after the electronic equipment collects the wireless scanning data of the target wireless access point each time, the residual collection times of the wireless scanning data of the target wireless access point in the period are updated.

Specifically, the remaining acquisition times of the wireless scanning data of the target wireless access point in the present period are reduced by 1. And after a period of time in the period, the electronic equipment judges whether to re-acquire the wireless scanning data of the target wireless access point according to the residual acquisition times of the wireless scanning data of the target wireless access point.

In addition, if the electronic device has transmitted wireless scan data of the target wireless access point to the server for a plurality of consecutive periods (e.g., consecutive days) within the allowable power consumption range, but the server has not yet generated the electronic fence of the target wireless access point (i.e., the electronic fence of the target wireless access point has not yet been updated), the electronic device may scan the target wireless access point for a plurality of consecutive times (e.g., consecutive twice) to acquire a plurality of wireless scan data in one acquisition, and transmit the plurality of wireless scan data to the server. That is, the electronic device reduces the remaining number of times of acquisition of wireless scan data of the target wireless access point only once, and increases the total number of times of acquisition of wireless scan data of all wireless access points in the present period only once.

According to the electronic fence data acquisition method and the electronic equipment, the electronic equipment maintains one residual acquisition frequency for each wireless access point instead of only maintaining the total frequency of acquiring wireless scanning data of all wireless access points. If the residual acquisition times are greater than zero, the electronic equipment scans the target wireless access point to acquire wireless scanning data, and sends the wireless scanning data to a server for updating the electronic fence by the server; and the electronic equipment updates the residual acquisition times after acquiring the wireless scanning data each time. When the remaining times of the wireless scanning data of one wireless access point collected by the electronic equipment is zero, the remaining collection times can be used for collecting the wireless scanning data of other wireless access points, so that the wireless scanning data of each wireless access point can be collected in an equalizing mode, and the server can generate the electronic fence of each wireless access point.

The above-mentioned electronic fence data collection method is described in detail below with reference to fig. 6.

S201, if the acquisition triggering condition is met, the electronic equipment acquires the identification of the target wireless access point. Otherwise, the process is directly ended.

This step refers to step S201, and is not described here.

If the remaining collection times of the wireless scanning data of the target wireless access point in the present period are in an invalid state, steps S202-S204 are executed. If the remaining acquisition time is in an active state in the present period, and the remaining acquisition time is greater than zero and less than or equal to the acquisition time threshold, steps S203-S204 are performed. If the remaining collection times are in a valid state in the period and the remaining collection times are equal to zero, ending the flow.

S202, the electronic equipment determines the initial value of the residual acquisition times of the wireless scanning data of the target wireless access point according to the update state of the electronic fence of the target wireless access point.

The step refers to step S102, and is not described herein.
