Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a method for determining the number of the population living in an area according to an embodiment of the present invention, where the embodiment is applicable to a case where the number of the population living in an area is counted, and the method may be executed by a device or a server for determining the number of the population living in an area according to an embodiment of the present invention, and the device may be implemented in a hardware and/or software manner. As shown in fig. 1, the method specifically comprises the following steps:
s101, determining the resident equipment number of the target area according to the resident position of the mobile equipment, wherein the resident position of the mobile equipment is determined according to the positioning track data of the mobile equipment and the equipment behavior characteristics related to the positioning track data.
The resident location of the mobile device may refer to a location area where the frequency of the mobile device is high for m consecutive months, and optionally, m may be greater than 6 months in the judgment standard of the population living normally. Since a mobile device is typically held by a user, the resident location of the mobile device is the location where the user of the mobile device lives for m months. Optionally, the resident location of the mobile device may include: the mobile subscriber's residence, the mobile subscriber's units, or the frequent mall streets. Alternatively, the present invention is used to determine the number of surviving people, and thus, the mobile user may have m consecutive months of residence as the resident location of the mobile device. The target area may refer to an area to be subjected to demographics, which may be a country, province, city, county, etc., and may also be divided according to a certain rule, such as the Yangtze river delta area, the Zhujiang delta area, etc. The Positioning track data of the mobile device may be Positioning track data obtained by acquiring Positioning data (i.e., geographical position coordinate data of the mobile device) of the mobile device by a satellite Positioning module (e.g., a Global Positioning System (GPS)) configured on the mobile device and processing the Positioning data within a period of time. The device behavior feature associated with the positioning track data may be a behavior feature of the mobile device corresponding to the mobile device when the mobile device acquires each positioning data in the positioning track data, for example, the feature may include at least one of a time distribution of the mobile device corresponding to the acquisition of each positioning data, information of a point of interest near a current location, search behavior information on the mobile device, or a network type to which the mobile device is connected.
Optionally, in the embodiment of the present invention, to determine the number of devices resident in the target area, the location of each mobile device needs to be determined. Specifically, when the resident position of the mobile device is determined according to the positioning track data of the mobile device and the device behavior feature associated with the positioning track data, whether the device behavior feature associated with the positioning track data meets the preset requirement or not may be analyzed, and then the resident position of the mobile device is determined from the positioning track data. For example, according to the habit that people usually have a rest at home at night, the time distribution corresponding to the positioning track data of m months is analyzed, and the position area where the time distribution of the positioning track data is distributed at night and the occurrence frequency of the positioning track data is the highest is selected as the resident position of the mobile device; or according to the habit that people usually connect with a fixed type network in the home after returning home, analyzing the network type connected with the mobile equipment corresponding to the positioning track data of m months, and selecting a position area with the highest frequency of the same network type in the positioning track data as the resident position of the mobile equipment; the method can also be characterized in that according to the characteristic that the position of the interest point is fixed, nearby interest point information corresponding to the positioning track data of m months is analyzed, and a position area with the highest occurrence frequency of the same interest point information in the positioning track data is selected as a resident position of the mobile equipment; or analyzing the search behavior of the mobile device corresponding to the positioning track data of m months according to the habits of news, weather, maps and the like of the area where the user usually pays more attention to, and taking the position area with the highest occurrence frequency of the search target area corresponding to the search behavior as the resident position of the mobile device.
Optionally, in order to improve the accuracy of determining the resident location of the mobile device, at least two of the above determination methods may be combined to determine the resident location of the mobile device from the positioning track data. Specifically, similar to the above determination method, a determination condition may be set for each device behavior feature, the device behavior feature corresponding to the positioning track data of m months is analyzed, and a location area corresponding to a determination condition that continuously satisfies a certain device behavior feature or a determination condition that continuously satisfies all device behavior features is used as the resident location of the mobile device.
Alternatively, the resident location of each mobile device may be determined according to a pre-trained neural network-based resident location determination model, specifically, the positioning track data of the mobile device for m months and the device behavior characteristics associated with the positioning track data may be input into a trained resident location determination module, and the model outputs the resident location of the mobile device through analysis.
For example, when the number of the resident devices in the target area is determined based on the resident locations of the mobile devices, the number of the mobile devices corresponding to the resident location information in the target area may be searched from the resident location information of all the mobile devices counted by the server after the resident locations of the mobile devices are determined, and the number of the resident devices in the target area may be determined.
And S102, determining the number of the permanent population of the target area according to the number of the resident devices of the target area.
The population of the permanent population refers to the population living at home for more than 6 months all the year round, and also includes the floating population living in cities for more than 6 months.
For example, when the number of the target area permanent population is determined according to the number of the resident devices in the target area, the number of the resident devices continuously resident in the target area for more than 6 months in the target area may be used as the number of the target area permanent population.
Optionally, in order to improve the accuracy of determining the number of the permanent population of the target area, the number of the permanent population of the target area may be determined according to the number of the resident devices of the target area and the population fitting coefficient of the target area. The population fitting coefficient of the target area may be calculated and determined according to a certain operational relationship between the historical resident device number and the actual population number of the target area, and may be used to estimate parameter values of the resident device number and the actual population number of the current target area. Specifically, when the number of the resident devices in the target area and the population fitting coefficient of the target area are determined, the number of the resident devices in the target area may be obtained by multiplying the number of the resident devices in the target area by the population fitting coefficient of the target area, or may be determined by being introduced into other formulas, which is not limited in the present invention.
The embodiment provides a method for determining the number of the permanent population of an area, which determines the number of resident devices in a target area according to positioning data of a mobile device and device behavior characteristics associated with the positioning data, and further determines the number of the permanent population of the target area. The number of the permanent population in any area in the city can be mastered, the area precision is improved, and the accuracy of the number of the permanent population is improved.

As shown in fig. 2, the method includes:
s201, clustering positioning track data of the mobile equipment to obtain at least one track cluster.
Optionally, the clustering of the positioning track data is a process of dividing each set of positioning data in the positioning track data into track clusters having the same characteristics. Specifically, when clustering is performed on each positioning data in the positioning track data, the positioning data belonging to the same time period in the positioning track data may be clustered according to a time characteristic to obtain a track cluster in the time period, for example, the positioning data belonging to the same time period from eight am to ten am in the positioning track data may be clustered into a track cluster, and the positioning data belonging to the same time period from ten am to two pm in the positioning track data may be clustered into another track cluster; or clustering the positioning data in the same area in the positioning track data according to the area characteristics to obtain a track cluster of the area, for example, clustering the positioning data in the positioning track data and the positioning data in a street area belonging to a certain city into a track cluster. Other clustering manners can be selected in the embodiment of the present invention, which is not limited in this respect.
Optionally, the triggering condition for clustering the positioning track data of the mobile device may be that, every time a preset period (for example, one day) is reached, clustering the positioning data of the mobile device in the period is triggered, or the acquired positioning data is stored in the server, and when the storage memory of the server is smaller than a preset threshold, clustering the positioning data of the mobile device is triggered, and the like, which is not limited in the embodiment of the present invention.

Optionally, the device behavior feature of each track cluster may be extracted by the feature extraction module on the mobile device from data used by the mobile device or applications accessed from the mobile device, when the positioning module on the mobile device obtains the positioning data of the mobile device.
Optionally, when the resident location cluster is selected from the at least one track cluster according to the device behavior characteristics of each track cluster, a determination condition may be set according to each device behavior characteristic, and the resident location cluster may be selected from the at least one track cluster according to the determination condition corresponding to the set one or more device behavior characteristics. The resident position cluster determination model based on the neural network can be trained to judge whether each track cluster is a resident position cluster or not according to the equipment behavior characteristics of each track cluster. Specifically, the resident location cluster determination model may be a binary classification model, and each trajectory cluster and its corresponding device behavior characteristics may be input into a trained binary classification model, which may analyze and output a judgment whether the trajectory cluster is a resident location cluster; the resident location cluster determination model may also be a selection model, and all the trajectory clusters and their corresponding device behavior characteristics are input into a trained selection model, and the model selects a resident location cluster from a plurality of trajectory clusters through analysis.
Optionally, the resident location cluster determination model in the embodiment of the present invention may be a machine learning model, and may collect training samples in advance, train the initial neural network model based on the collected training samples, and finally obtain a resident location cluster determination model for selecting a resident location from at least one track cluster. For example, the elements included in each set of training samples may include: a plurality of track clusters corresponding to the mobile device, device behavior characteristics associated with each track cluster, and a resident location cluster of the mobile device. The algorithms employed may include Recurrent Neural Networks (RNNs), Long-Short Term Memory (LSTM) networks, threshold cycle units, simple cycle units, autoencoders, decision trees, random forests, feature mean classifications, classification regression trees, hidden markov, K-nearest neighbor (KNN) algorithms, logistic regression models, bayesian models, gaussian models, and KL divergences (Kullback-Leibler divergence), among others.

Optionally, in the embodiment of the present invention, there are many methods for determining the resident location of the mobile device according to each piece of track data included in the resident location cluster, which are not limited herein. For example, the center of the area may be used as the resident location of the mobile device by fitting the area enclosed by the trajectory data in the resident location cluster; the distribution density of each trace data in the resident position cluster may be analyzed, and the center of the area with the high distribution density of the trace data may be used as the resident position.
S204, determining the resident equipment number of the target area according to the resident position of the mobile equipment.

EXAMPLE III
Fig. 3 is a flowchart of a method for determining the number of the area permanent population according to a third embodiment of the present invention, which provides a preferred embodiment based on the above embodiments. As shown in fig. 3, the method includes:
s301, clustering positioning track data of the mobile equipment to obtain at least one track cluster.
Illustratively, a map software development platform (positioning SDK) and an equipment feature extraction module are deployed in each mobile equipment in advance, the positioning SDK acquires positioning data of the mobile equipment (the positioning SDK may acquire the positioning data in real time, or acquire the positioning data once every preset time interval, or start to acquire when the mobile equipment is detected to be in a motion state), the feature extraction module extracts behavior features of the mobile equipment when the positioning SDK acquires the positioning data, and uploads the positioning data and the behavior features of the mobile equipment associated with the positioning data to a server after a corresponding relationship is established between the positioning data and the behavior features of the mobile equipment. And after the server receives the positioning data sent by each mobile device and the device behavior characteristics corresponding to each positioning data, clustering the positioning data of each mobile device, and clustering at least one track cluster for each mobile device.

S303, determining the resident location of the mobile device according to each trace data included in the resident location cluster.
S304, determining the resident equipment number of the target area according to the resident position of the mobile equipment.
For example, when the number of the resident population in the target area is to be determined, the number of the mobile devices whose resident position coordinate information is within the target area coordinate range is counted as the number of the resident devices in the target area according to the resident position coordinate information of each mobile device determined in S303.
And S305, determining the number of the permanent population of the target area according to the number of the resident devices of the target area and the population fitting coefficient of the target area.
Optionally, the number of the permanent population of the target area is determined according to the number of the resident devices of the target area and the population fitting coefficient of the target area, and may be calculated according to the following formula:
s＝d×ait，
wherein s is the number of the permanent population of the target area, and d is the number of the resident equipment of the target area; a isitFitting coefficients for the population of the t year of the target city i.
For example, if the target city i belongs to the target area, when the number S of the population living in 2018 of the target area is to be determined, the number S of the resident devices in the target area determined in S304 may be multiplied by the population fitting coefficient in 2018 of the target city i.
Optionally, the population fitting coefficient of the target area may be determined by calculating according to a certain operational relationship between the historical resident device number and the actual population number of the target area, and specifically, the determining method of the population fitting coefficient of the target area includes the following steps:
A. and determining the historical resident equipment number of the target city to which the target area belongs.
The target area may be a country, province, city, county, etc., and may be divided according to a certain rule, such as the Yangtze river delta area, the Zhujiang river delta area, etc. Accordingly, the target city to which the target area belongs may be one or more.
Optionally, the historical resident device number of each city may be the resident device number of the previous year of the current year, or may be the average of the resident device numbers of the previous N (N is a positive integer greater than 1) years of the current year. The resident locations of the mobile devices are determined through S303 and then stored in the server, specifically, each city, the number of the resident devices corresponding to each city, and the year in which the resident locations are determined may be correspondingly stored in the server, and when the historical resident device number of the target city to which the target area belongs is determined, the target city may be directly searched from the server, and the historical resident device number of the target city may be obtained.
B. Acquiring the official historical frequent population number of the target city.
The official historical number of the permanent population of the city can be the number of the permanent population of each city published in the Chinese population information network in the past year. Alternatively, the number of the perennial population may be the number of the perennial population in the previous year of the year, or may be the average of the number of the perennial population in the previous N (N is a positive integer greater than 1) years of the year. The historical resident equipment quantity in the step a and the historical permanent population quantity in the step B have a certain corresponding relationship, if the historical resident equipment quantity is the previous year of the current year, the historical permanent population quantity is also the previous year of the current year, and if the historical resident equipment quantity is the previous N years of the current year, the historical permanent population quantity is also the previous N years of the current year.
Optionally, when acquiring the official historical population number of the permanent population of the target city, the server may search the target city and the year of the permanent population number to be acquired by accessing a website (such as a chinese population information network) for which the national official publishes population information, and further acquire the historical permanent population number of the target city; optionally, in order to prevent the problem that the acquisition of the historical population number of the permanent living is failed due to poor network, the server may store the historical population number of the permanent living in each city disclosed in the chinese population information network in the server when the network condition is good, and periodically detect whether the data in the chinese population information network is updated, and if so, update the data stored in the server. At the moment, the official historical frequent population number of the target city can be obtained by directly searching from the inside of the server, so that the searching efficiency is improved.
C. And determining population fitting coefficients of the target area according to the historical resident equipment number, the historical population number of the permanent dwellings and the natural growth rate of the historical permanent population of the target city.
The natural population growth rate is a ratio of a natural population increase (birth number minus death number) to an average population (or middle population) in a certain period (usually one year), and is generally expressed by a thousandth ratio, and a specific calculation formula may be: the natural growth rate of the population is (number of births within a year-number of deaths within a year)/average number of people per year multiplied by 1000 per mill.
Optionally, the population fitting coefficient of the target area is determined according to the historical resident device number, the historical population number of the permanent dwellings and the natural growth rate of the historical permanent population of the target city, and may be calculated according to the following formula:
wherein, aitFitting coefficients for the population of the t year of the target city i; c. Cit-1The number of resident equipment in the t-1 year of the target city i; git-1The official historical population number of the target city i in the t-1 year βiThe natural growth rate of the population is held for the history of the target city i.
For example, if the population fitting coefficient of the target city i in 2018 is to be determined, the population fitting coefficient of the target city i in 2018 may be determined based on the number of resident devices in the previous year (i.e., 2017) of the target city i, the number of official permanent population of the target city i in 2017, and the natural growth rate of the permanent population of the target city i from 2016 to 2017.
