It is obvious that the drawings in the following description are only some examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.
For the sake of simplicity, the drawings only schematically show the parts relevant to the present invention, and they do not represent the actual structure as a product. In addition, in order to make the drawings concise and understandable, components having the same structure or function in some of the drawings are only schematically illustrated or only labeled. In this document, "one" means not only "only one" but also a case of "more than one".
In one embodiment of the present invention, as shown in fig. 1, a method for generating a thermodynamic diagram of an active area includes:
s100, acquiring geomagnetic data from a mobile terminal carried by a user;
specifically, the geomagnetic field is an inherent resource of the earth, and provides a natural coordinate system for the positioning and navigation technology. The earth can be viewed as a magnetic dipole (magnetic dipole) in which one pole is located near a geographic north pole and the other pole is located near a geographic south pole. Since the geomagnetic field is a vector field, in the earth near-earth space, the geomagnetic vector of any place is different from the vectors of other places, and there may be a one-to-one correspondence relationship with the longitude and latitude of the place. The mobile terminal that the user generally used often installs earth induction sensor, and after mobile terminal gathered earth magnetic data, uploaded earth magnetic data to the server through wireless communication mode (for example WIFI communication or bluetooth communication etc.).
S200, inquiring a geomagnetic fingerprint map according to the geomagnetic data to obtain a current resident place of the user;
s300, calculating the residence time of the user at the current residence place according to the acquisition time of the geomagnetic data acquired from the mobile terminal carried by the user;
specifically, when the mobile terminal carried by the user acquires the geomagnetic data, a timestamp is the acquisition time of the geomagnetic data, and the residence time of the user at the current residence place is calculated according to the acquisition time of the geomagnetic data. Suppose that the acquisition time of the mobile terminal of the user A for acquiring the geomagnetic data is 20:00:00 in 10 and 7 months in 2018, and the position coordinate corresponding to the geomagnetic data is A. If the position coordinate corresponding to the geomagnetic data obtained by the mobile terminal of the user A is still A in 2018, 10/7/20: 01:00, and the position coordinate corresponding to the geomagnetic data obtained by the mobile terminal of the user A in 2018, 10/7/20: 01:01 is B, the residence time of the user A at the position where the position coordinate is A can be calculated to be 1 min. Here, it is only an example, the acquisition time may be accurate to millisecond, and in short, the residence time corresponding to the position where each user is located at different position coordinates is obtained by calculation according to the requirement.
S400, carrying out weighting calculation according to the current residence site and the residence time to obtain a weighted hot point value of the current residence site, switching to the next residence site until the weighted hot point values of all residence sites in the target area are obtained through calculation, and generating an activity area thermodynamic diagram according to all the weighted hot point values.
Specifically, the residence time corresponding to the position of the coordinate at the same position of different users is obtained through calculation, and the weighted hot point value of the current residence point is obtained through calculation according to the current residence point and the residence time corresponding to the current residence point. Similarly, the residence time corresponding to the positions of the coordinates of different positions of different users can be obtained, so that the weighted hot point value of each residence point in the target area is obtained through calculation. And after the weighted hot point values corresponding to all the positions in the target area are obtained through calculation, generating an activity area thermodynamic diagram according to the weighted hot point values.
In this embodiment, with the development of the mobile internet technology, the location service has gained wide attention. According to statistics, more than 80% of the information used by people is related to the position, and the demand of people for indoor and outdoor seamless positioning is increasing. Although indoor positioning technologies based on technologies such as Wi-Fi, ZigBee, RFID, Bluetooth and ultra wideband exist, the realization of the indoor positioning technology is difficult to popularize and apply due to the defects that a large number of nodes need to be arranged, the signal coverage cost is high and the like. As the earth magnetism belongs to the attribute of the earth, corresponding earth magnetism data can be obtained at any position as long as a mobile terminal carried by a user is provided with the earth magnetism induction sensor, and therefore, extra equipment and cost cannot be increased. Through effective algorithm, the precision can be controlled within the range of 1m by geomagnetic positioning, so that absolute position positioning can be implemented indoors, and accurate position information of customers can be ensured to be obtained indoors. Any geomagnetic data query to obtain corresponding position coordinates needs to be queried and matched through the server, so that the residence time of each customer at the corresponding position on the plane map can be obtained. By weighting the time distribution of all customers on the plane map, the activity area thermodynamic diagram corresponding to the whole target area range can be obtained. This scheme makes the trade company need not to increase extra hardware equipment, only needs the corresponding APP of mobile terminal installation such as customer's cell-phone, IPAD to gather earth magnetism data in real time and just can carry out accurate location, reduces the maintenance cost in equipment later stage to realize the low-cost purpose that obtains the regional thermodynamic diagram of activity, improve the trade company and use experience.

S230, when geomagnetic fingerprint information matched with the geomagnetic data does not exist, calculating according to preset positioning data to obtain corresponding position coordinates;
s240, determining the spatial position of the position coordinate obtained by calculation as the current resident position of the user;
specifically, as the geomagnetic data is acquired by the geomagnetic induction sensor in real time, there may be a measurement error due to the influence of the external environment, or a corresponding relationship between a position coordinate and geomagnetic fingerprint information is not acquired and bound to a part of the position in a possible target area, so that the geomagnetic fingerprint information matched with the geomagnetic fingerprint map cannot be identified from the geomagnetic fingerprint map. The preset bit data includes, but is not limited to, WiFi data, bluetooth data, motion data. And when geomagnetic fingerprint information matched with the geomagnetic data does not exist, calculating to obtain corresponding position coordinates according to preset positioning data, and determining the spatial position where the calculated position coordinates are located as the current resident place of the user.

According to the invention, geomagnetic data and preset positioning data (WiFi data, Bluetooth data, motion data and the like) are combined, accurate positioning in a local area range is carried out by taking relatively stable signal geomagnetism as a main body, WiFi positioning or inertial navigation positioning or Bluetooth positioning is taken as assistance, and geomagnetic positioning blind spots are reduced, so that indoor high-precision and low-power-consumption real-time positioning is realized, meanwhile, the later-stage maintenance cost of equipment is reduced, the purpose of acquiring a thermodynamic diagram of an activity area at low cost is realized, and the use experience of a merchant is improved.

Specifically, a planar map of a target area is established in advance, the target area has a plurality of spatial positions, and each spatial position corresponds to a respective position coordinate. The device comprises a server, a geomagnetic sensor and a geomagnetic sensor, wherein the geomagnetic sensor is arranged at the current space position, the geomagnetic fingerprint information at the current space position is sensed through the device with the geomagnetic sensor, the device with the geomagnetic sensor transmits the geomagnetic fingerprint information at the current space position to the server, and the server binds the geomagnetic fingerprint information at the current space position with the position coordinate corresponding to the current position, so that the binding of the position coordinate of one space position and the geomagnetic fingerprint information is completed.

Mobile terminals such as mobile phones of customers Cn are provided with business APPs, and geomagnetic data of the positions of the customers Cn are acquired in real time through geomagnetic induction sensors inside the mobile terminals. And judging the current residence place of the customer Cn according to the geomagnetic data of the position of the customer Cn. The position coordinates of the customer Cn in the shopping mall can be obtained through the obtained geomagnetic data and the geomagnetic fingerprint map.

And after the residence time of the user at different positions is calculated, weighting the residence time of all the users at different residence places to obtain the activity area thermodynamic diagram of the whole market. In the scheme, equipment cannot be additionally added, so that the later maintenance cost of the equipment cannot be caused. Once the corresponding relationship graph of the plane map and the geomagnetic map of the mall, that is, the geomagnetic fingerprint map of the mall is established, the updating and synchronization are required to be performed once in 5 years generally. To the user, only need handheld mobile terminal such as a cell-phone that possess earth induction sensor, install corresponding market APP and can realize accurate location, use very friendly, when having realized indoor high accuracy, low-power consumption location in real time, reduce the maintenance cost in equipment later stage to realize the low-cost purpose of obtaining the regional thermodynamic diagram of activity, improve the trade company and use and experience.
