In order to solve the problems in the prior art, embodiments of the present invention provide a positioning method, an apparatus, an electronic device, and a computer-readable storage medium.
The following describes a positioning method provided by an embodiment of the present invention with reference to fig. 1.
It is to be understood that the positioning method provided by the embodiment of the present invention may be applied to a server, and is not limited thereto.
Referring to fig. 1, a positioning method provided by an embodiment of the present invention may include the following steps:
s101: acquiring wireless network information identified by first electronic equipment as first wireless network information;
it is understood that the first electronic device includes, but is not limited to: the intelligent wearable device comprises a smart phone, a learning machine and intelligent wearable devices such as a smart watch and a smart bracelet which are wearable on a user.
In addition, when the first electronic device is located in an area, the first electronic device can recognize wireless network information corresponding to the wireless network transmitting devices in the area. Wherein the wireless network transmitting device includes, but is not limited to, a router.
For example, the first electronic device may recognize a Media Access Control (MAC) corresponding to a router in the school zone, that is, obtain a physical address corresponding to the router. In addition, the wireless network identifier corresponding to the wireless network signal transmitted by the router and the signal strength corresponding to the wireless network identifier can also be identified, but the invention is not limited thereto.
After identifying the wireless network information, the first electronic device may report the wireless network information to the server. Therefore, the server can obtain the wireless network information reported by the first electronic device as the first wireless network information.
S102: searching second wireless network information matched with the first wireless network information in a first preset positioning database, and searching second positioning data having a mapping relation with the second wireless network information; wherein, record has in the first preset positioning database: the mapping relation between the second wireless network information and second positioning data, wherein the second positioning data are accurate positioning data of the first electronic equipment;
it is understood that the server may construct the first preset location database before performing the operation of S102. The method for constructing the first preset location database may be as follows:
acquiring wireless network information identified by the second electronic equipment as second wireless network information; acquiring accurate positioning data corresponding to second electronic equipment input by a user as second positioning data; when the times of inputting the second wireless network information and the second positioning data by the user are larger than a preset threshold value, constructing a mapping relation between the second wireless network information and the second positioning data; and storing the mapping relation into a first preset positioning database.
It is understood that the second electronic device includes, but is not limited to: the intelligent wearable device comprises a smart phone, a learning machine and intelligent wearable devices such as a smart watch and a smart bracelet which are wearable on a user. It is reasonable that the second electronic device is the same electronic device as the first electronic device, or may be a different electronic device.
In addition, when the second electronic device is located in an area, the second electronic device can also recognize wireless network information corresponding to the wireless network transmitting device in the area. And, the wireless network information may be reported to the server. Therefore, the server can obtain the wireless network information reported by the second electronic device as the second wireless network information.
Moreover, after the server obtains the second wireless network information reported by the second electronic device, the server can also obtain accurate positioning data corresponding to the second electronic device, which is input by the user, as second positioning data. Therefore, when the user knows the accurate positioning data of the second electronic device, the data correction can be carried out on the positioning data of the second electronic device, and then the server can obtain the accurate positioning data of the second electronic device.
When the server obtains the second wireless network information and the second positioning data corresponding to the second electronic device, a mapping relationship between the second wireless network information and the second positioning data can be constructed, and the mapping relationship is stored in the first preset positioning database. In order to ensure that the second positioning data recorded in the first preset positioning database is accurate and real positioning data, the server can also construct a mapping relation between the second wireless network information and the second positioning data when detecting that the times of inputting the second wireless network information and the second positioning data by the user is greater than a preset threshold value. Therefore, the first preset positioning database recorded with the mapping relation between the second wireless network information and the accurate positioning data can be constructed in advance, and the first preset positioning database is conveniently and subsequently utilized for accurate and quick positioning.
The value of the preset threshold may be 10, but is not limited thereto.
In addition, in order to accurately perform positioning, after the mapping relationship is stored in the first preset positioning database, whether the update time of the first preset positioning database is reached or not can be detected. When the update time is reached, the mapping relation stored in the first preset location database may be deleted, and an operation of obtaining the wireless network information identified by the second electronic device as the second wireless network information may be triggered. Therefore, the mapping relation stored in the first preset positioning database can be updated, and the second positioning data searched based on the first preset positioning database is the latest and accurate positioning data.
In the embodiment of the present invention, when the first wireless network information includes: the physical address of the wireless network transmitting device, the target sequence ordered according to the identification sequence of the wireless network identifier, and the operation of searching the second wireless network information matched with the first wireless network information in the first preset location database when the signal strength corresponding to the wireless network identifier is reached may specifically be: and searching whether second wireless network information comprising a physical address, target sequencing and signal strength exists in a first preset positioning database.
In this way, it is possible to find out whether there is second wireless network information matching the first wireless network information in the first preset positioning data based on the physical address, the target rank and the signal strength. Therefore, the searched second wireless network information is information matched with the physical address, the target sequence and the signal intensity, namely the environment where the first electronic equipment is located is more similar to the second positioning data corresponding to the second wireless network information. That is, more accurate positioning data can be found. It can be understood that, when the wireless network information identified by the two electronic devices is the same, the two electronic devices are assumed to be located at the same geographic location.
In addition, when the second positioning data cannot be found in the first preset positioning database, the second positioning data of the first electronic device can be determined through the base station information. Specifically, the server may obtain, as the first base station information, base station information identified by the first electronic device. And then, searching second base station information matched with the first base station information in a second preset positioning database, and searching second positioning data having a mapping relation with the second base station information. Wherein, the second preset positioning database records: and the mapping relation between the second base station information and the second positioning data. Then, the second positioning data found in the second preset positioning database may be used as the positioning data of the first electronic device.
It can be understood that, when the base station information identified by the two electronic devices is the same, the two electronic devices are considered to be located at the same geographical location. The base station information may also be referred to as a base station signal. In this way, the server may determine the positioning data of the first electronic device by using the base station information when the positioning data of the first electronic device cannot be determined by the first wireless network information.
In addition, it can be understood that when the second positioning data cannot be found in the second preset positioning database, the global positioning system information received by the first electronic device can be obtained. In this way, when the global positioning system information received by the first electronic device can be acquired, the global positioning system information can be used as the positioning data of the first electronic device. In this way, when the first electronic device cannot be located through the wireless network information and the base station information, the first electronic device can also be located through the global positioning system information.
S103: and taking the searched second positioning data as the positioning data of the first electronic equipment.
In the embodiment of the present invention, when the first electronic device needs to be located, the wireless network information identified by the first electronic device may be obtained as the first wireless network information. Then, the second wireless network information matching with the first wireless network information can be searched in the first preset positioning database, and the second positioning data having a mapping relation with the second wireless network information can be searched. Wherein, the record has in this first preset position database: the mapping relationship between the second wireless network information and the second positioning data is the accurate positioning data of the first electronic device. Therefore, the accurate positioning data corresponding to the first wireless network information can be searched through the first preset positioning data which is constructed in advance. Therefore, the accurate positioning data corresponding to the first electronic equipment can be quickly obtained, and the positioning speed and accuracy are improved.
After the server obtains the wireless network information identified by the first electronic device as the first wireless network information, it may further determine whether the first wireless network information includes a wireless network identifier. If the wireless network identification is contained, whether the wireless network identification is stored in the wireless network identification library or not can be judged. The wireless network identification library records wireless network identifications existing in a preset safety area.
If the wireless network identifier is stored, it indicates that the first electronic device is in the preset security area, and at this time, it may be determined that the security state of the first electronic device is the security area state. In addition, if the wireless network identifier is not stored, it indicates that the first electronic device is not in the preset security area, and at this time, it may be determined that the security state of the first electronic device is the state of not entering the security area.
In this way, it may be determined whether the first electronic device enters a preset security zone and the security status may be transmitted to a supervising user device (e.g., a parent user device) associated with the first electronic device, thereby alerting a user of the first electronic device to be in or out of the preset security zone.
In addition, if the first wireless network information does not include the wireless network identifier, the server may determine whether the location information included in the second positioning data is located in the preset security area after the found second positioning data is used as the positioning data of the first electronic device.
If the first electronic device is located in the preset safe area, it indicates that the position information included in the second positioning data is located in the position area corresponding to the preset safe area, and at this time, it may be determined that the safe state of the first electronic device is the safe area state. In addition, if the first electronic device is not located in the preset safe area, it indicates that the position information included in the second positioning data does not fall within the position area corresponding to the preset safe area, and at this time, it may be determined that the safe state of the first electronic device is not entered into the safe area state. Thus, whether the first electronic device enters the preset safe area can be determined through the positioning data of the first electronic device. Further, whether the security state corresponding to the preset security zone is entered or not may be sent to a monitoring user device (e.g., a teacher user device) associated with the first electronic device, so as to prompt a user of the first electronic device to be in the preset security zone or not.
The following describes a positioning method provided by an embodiment of the present invention with reference to fig. 2. Referring to fig. 2, the positioning method may include the steps of:
s1: acquiring wireless network information identified by the electronic equipment, and determining positioning data of the electronic equipment based on the wireless network information;
