In order to better understand the technical solutions of the present invention, the following detailed descriptions of the technical solutions of the present invention are provided with the accompanying drawings and the specific embodiments, and it should be understood that the specific features in the embodiments and the examples of the present invention are the detailed descriptions of the technical solutions of the present invention, and are not limitations of the technical solutions of the present invention, and the technical features in the embodiments and the examples of the present invention may be combined with each other without conflict.
In a first aspect, an embodiment of the present invention provides an information processing method, please refer to fig. 1, including:
step S101: determining N pieces of access point information in a connection range of the electronic equipment, wherein N is a positive integer;
step S102: matching the N pieces of access point information in a first data set to obtain height data of N access points corresponding to the N pieces of access point information, wherein the first data set comprises a first corresponding relation between each access point and the height data of the access point;
step S103: determining altitude data of the electronic device based on the altitude data of the N access points.
For example, the solution may be applied to electronic devices capable of connecting to an access point, such as: cell-phone, panel computer, notebook computer, intelligent wrist-watch, intelligent bracelet etc. this access point is for example: WIFI access point, base station etc. under general condition, the distribution range of WIFI access point is more extensive, if this access point is the WIFI access point, can obtain the height data of more accurate electronic equipment. Alternatively, the solution may also be applied to a server, and after receiving a request (for example, a positioning request) of the electronic device for obtaining the height data, the server determines the height data of the electronic device based on the steps S101 to S103, and sends the height data to the electronic device.
In step S101, when the electronic device needs to acquire altitude data, it may search for at least one piece of access point information nearby, and then determine N pieces of access point information from the at least one piece of access point information, where an access point is a WIFI access point, for example, a user is located indoors, and when the user wishes to perform positioning, the user finds that there is no GPS signal indoors, so that the user chooses to perform positioning through a network positioning server by means of WIFI (or a base station), and when performing positioning, the electronic device first sends WIFI information to the network positioning server, where the WIFI information includes, for example: the method comprises the steps that the MAC address of the electronic equipment, the signal intensity of each WIFI which can be detected, the MAC address and the information such as each WIFI encryption mode and the connection state can be further included, the network positioning server determines N pieces of WIFI information based on the WIFI information, and the height data of the electronic equipment are calculated through the N pieces of WIFI information. Wherein the at least one access point information can be used as N access point information for subsequent calculation of the electronic device; still alternatively, after obtaining at least one piece of access point information, the N pieces of access point information whose signal strengths satisfy the preset strength condition may be determined by the signal strength of the at least one piece of access point information, for example: the at least one piece of access point information can be sorted from high to low according to the signal strength, and then the access point information sorted at the front preset position (for example: 4, 5, etc.) is obtained as N pieces of access point information; for another example, access point information having a signal strength greater than a preset signal strength may be acquired as the N pieces of access point information, and so on. The access point information includes, for example, identification information of each access point, where the identification information is, for example: MAC (Medium Access Control) address, unique number, etc.
In step S102, a first corresponding relationship between the access point information and the altitude data may be pre-established, and then the first corresponding relationship is added to the first data set, please refer to fig. 2, the first corresponding relationship may be established and added to the first data set in the following manner:
step S201: determining the position information and the high-altitude air pressure data of each access point;
step S202: determining ground air pressure data of an area where each access point is located in a second data set based on the position information of each access point, wherein the second data set comprises a second corresponding relation between the position information of each area and the ground air pressure data;
step S203: determining the relative height of each access point from the ground of the position of the access point based on the high air pressure data of the access point and the ground air pressure data of the area where the access point is located;
step S204: determining the first correspondence for each access point based on the relative altitude of the respective access point and adding the first correspondence to the first set of data.
In step S201, access points located in the air (i.e., access points not located on the ground) may be first selected, and then, air pressure data (e.g., air pressure values) of the locations of the access points are collected by air pressure sensors of the access points, where the air pressure data are the air pressure data of the air; the position information of the access point can be acquired through a positioning device (such as a GPS positioning device, a base station positioning device, a WIFI positioning device and the like) carried by the access point; the position information of each access point can also be acquired and obtained at each access point by manually carrying a positioning device, which is not limited in the embodiments of the present invention.
In step S202, a second data set may be obtained by the following steps: acquiring parameter information of each sampling device in advance, wherein each parameter information comprises position information of the sampling device and ground air pressure data; dividing each sampling device into a plurality of areas through the position information; adding the second correspondence comprising location information and ground pressure data for each region to the second data set.
For example, electronic devices located on the ground can be obtained as sampling devices, then, air pressure data (for example, air pressure values) of the positions of the electronic devices are obtained through the acquisition of air pressure sensors of the electronic devices, the air pressure data are ground air pressure data, and meanwhile, the position information of the electronic devices is obtained through the detection of positioning devices externally connected or internally arranged with the sampling devices; after determining the location information of each sampling device, each sampling device may be divided into a plurality of regions, for example, each sampling device may be divided into a plurality of regions according to a predetermined size of each region, for example: each area can be evenly divided directly through the longitude and latitude, and then the sampling equipment is divided into areas corresponding to the longitude and latitude; still alternatively, the respective sampling devices may be divided into a plurality of regions by a predetermined number of devices per region, for example: each area may be divided by latitude and longitude, then the number of sampling devices included in each area is determined, whether the number is greater than a preset number (for example, 100, 500, and the like) is determined, and if the number is greater than the preset number, the area is further divided, so that an index mechanism for indexing the location area grid from low resolution to high resolution is established, so as to improve the accuracy of the established second correspondence. After the area is divided into a plurality of areas, the ground air pressure data of each area can be determined, a second corresponding relation between the position information of each area and the ground air pressure data is further established, and then the second corresponding relation of each area is added into a second data set, so that the ground air pressure data of the area where the corresponding access point is located can be searched and obtained in the second data set based on the position information of the access point.
In a specific implementation process, since one area often comprises a plurality of electronic devices, the ground air pressure data acquired by the plurality of electronic devices can be averaged to obtain the ground air pressure data of the area; alternatively, the ground pressure data at the middle position is taken from the ground pressure data collected by the plurality of electronic devices as the ground pressure data of the area, and the like.
As an alternative embodiment, when the second data set is established, the ground elevation data of each sampling device may be obtained, where the ground elevation data refers to poster data of the ground level of each sampling device, and may be obtained through GPS signal detection, so that the second corresponding relationship included in the second data set may include the ground elevation data of each region in addition to the position information and ground pressure data of each region.
In step S203, the relative height of each access point from the ground where the access point is located can be calculated by the following formula:
wherein a represents an altitude;
P0represents standard atmospheric pressure;
p represents the collected high altitude air pressure data for the access point or the ground air pressure data for the location.
Δh＝A1-A2---------------------------------------[2]
Wherein Δ h represents the relative height of the access point from the ground location where the access point is located;
A1is determined based on high altitude air pressure data of the access point (such as air pressure values acquired by an air pressure sensor at high altitude);
A2is ground altitude data determined based on ground pressure data (e.g., barometric pressure values collected at the ground by a barometric pressure sensor) of the access point.
In step S204, the height data in the first corresponding relationship may be a plurality of different height data, and further the first corresponding relationship included in the first data set is different, for example: the first corresponding relation including the identification information of each access point and the relative height between the identification information of each access point and the ground where the access point is located is directly established, and then the first data set can include the corresponding relation between the identification information of each access point and the relative height, so that the relative height of each access point can be found through the identification information of each access point in the follow-up process. Determining actual altitude data of corresponding access points based on the relative height of each access point and the ground altitude data of the area where each access point is located; adding the first corresponding relationship containing the identification information of each access point and the actual altitude data into the first data set, for example, if the second corresponding relationship also contains the ground altitude data of each area, the following parameter information of each access point can be firstly found and obtained based on the second corresponding relationship: the ground altitude data of the area and the ground air pressure data of the area are obtained by calculating the relative height of the corresponding access point based on the ground air pressure data of the area and a formula [1], and then adding the ground altitude data of the corresponding access point to the relative height of the corresponding access point to obtain the actual altitude data of the corresponding access point, so that the first data set contains a first corresponding relation between the identification information of each access point and the actual altitude data of the access point, and the actual altitude data of the corresponding access point can be obtained by searching the first data set through the identification information of the access point in the follow-up process.
In a specific implementation process, in the establishing of the first corresponding relationship of each access point, the first corresponding relationship of each access point may be added to the first data set, so that the altitude data of the corresponding access point may be obtained by searching in the first data set through the access point information.
In step S103, the first data set may be searched for the identification information of each of the N access points, and the matched altitude data is obtained as the altitude data of the N access points.
In the specific implementation process, each access point has a code or number, the code or number is identification information of the access point, and the first data set can be queried through the code or number (namely, the identification information) of the access point; the code or number of each access point in the N access points may be matched with the code or number of each access point in the first data set, and the height data matched with the code or number of the corresponding access point may be used as the height data of the corresponding access point.
If the first correspondence in the first data set includes: the corresponding relation between the identification information of the access point and the relative height is searched, the obtained height data of the N access points is the relative height of the N access points, and therefore the determined height data of the electronic equipment is also the relative height of the electronic equipment from the ground where the electronic equipment is located; if the first correspondence in the first data set includes: the corresponding relation between the identification information of the access points and the actual altitude data is found, the obtained height data of the N access points is the actual altitude data of the N access points, and therefore the determined height data of the electronic equipment is also the actual altitude data of the electronic equipment.
In step S103, after determining the altitude data of each access point in the N pieces of access point information, the altitude data of the electronic device may be determined in various ways, which are described below by way of example, and of course, in the specific implementation process, the method is not limited to the following two cases.
First, the determining altitude data of the electronic device based on the altitude data of the N access points includes: and adding the height data of the N access points based on the weight values and averaging to obtain the height data of the electronic equipment.
For example, the weight values of the height data of the N access points may be the same, and in this case, the height data of the electronic device can be obtained by directly averaging the height data of the N access points; still alternatively, the weight values of the height data of the N access points may also be different, for example: the weight of the access point is in positive correlation with the signal intensity thereof, and then the height data of the electronic device can be calculated by the following formula:
wherein H represents height data of the electronic device;
kirepresents the weight value of the ith access point, where k1+k2……+kN＝1；
hiIndicating altitude data for the ith access point.
In general, the stronger the signal strength of the access point, the closer the access point is to the electronic device, in which case the height data is more valuable, and thus the weight of the access point is positively correlated with the signal strength thereof, so that more accurate height data of the electronic device can be obtained.
Secondly, the determining the altitude data of the electronic device based on the altitude data of the N access points includes: and selecting one height data from the height data of the N access points as the height data of the electronic equipment. For example: selecting the altitude data of the access point with the highest signal strength from the N access points as the altitude data of the electronic device, randomly selecting one altitude data from the altitude data of the N access points as the altitude data of the electronic device, and the like.
In the implementation, after obtaining the height data of the electronic device based on step S103, the height data may be provided to the user at various occasions, for example: positioning instructions can be received; and responding to the positioning instruction, and providing positioning data containing the height data to a user of the electronic equipment. That is, when the electronic device performs positioning, the electronic device is provided with some common positioning data (such as street name, current position, etc.), and height data of the electronic device, so that the positioning is more accurate. It is also possible to acquire the height data of the electronic device and provide it to the user of the electronic device or the like after detecting the height acquisition instruction.
