An indoor positioning method provided by the embodiment of the invention is described below by taking a terminal device as an example.

The indoor positioning method provided by the embodiment of the invention can be applied to a scene of indoor positioning of the terminal equipment which is started up for the first time.

Example 1

As shown in fig. 1, an embodiment of the present invention provides an indoor positioning method, which may include the following steps:

101. the terminal equipment acquires the received information of the N wireless local area networks.

After the terminal equipment is started up for the first time, the terminal equipment acquires the received information of N wireless local area networks.

In the embodiment of the invention, the information of the wireless local area network comprises: and receiving signal intensity or receiving signal intensity and identification information, wherein N is an integer greater than or equal to 1.

Optionally, the received signal strength in the embodiment of the present invention may be used to measure the strength of a received signal of a wireless lan.

In the embodiment of the invention, two types of physical quantities can be adopted to represent the received signal strength, namely dBm and asu.

Wherein dBm is a ratio based on 1mW power, and a specific calculation formula is as follows:the dBm value is negative and a larger value indicates a stronger received signal strength.

asu is a unique signal unit defined for a terminal device configuring an android system and may represent a signal transmission rate between the terminal device and a device (e.g., a router or a base station) transmitting the received signal, the asu value is a positive number, and a larger value indicates a stronger received signal strength. There is a certain conversion relation between dBm and asu, dbm= -113+2 asu.

As an alternative implementation manner, obtaining the received information of N wireless local area networks may include two implementation manners:

the implementation mode is as follows: and responding to a first instruction sent by the user, and acquiring the received information of the N wireless local area networks by the terminal equipment.

After the terminal equipment is started up for the first time, the terminal equipment can respond to a first instruction sent by a user to acquire the received information of the N wireless local area networks. The first instruction is used for indicating to acquire information of the wireless local area network.

The implementation mode II is as follows: and responding to a second instruction sent by target equipment associated with the terminal equipment, and acquiring the received information of the N wireless local area networks by the terminal equipment. The second instruction is used for indicating the terminal equipment to acquire the information of the wireless local area network.

After the terminal equipment is started up for the first time, the received information of N wireless local area networks is obtained in response to a second instruction sent by an associated user of target equipment associated with the terminal equipment.

It should be noted that the first instruction and the second instruction may specifically have various forms, for example, a clicking operation of a virtual control or a physical button in the terminal device by a user, or a gesture instruction set by the user, or a voice instruction related to positioning input by the user, which is not limited in the embodiment of the present invention.

The optional implementation manner can respond to the instruction sent by the user or the user of the target device associated with the terminal device to acquire the received information of the N wireless local area networks.

If the first user of the terminal device is a minor, the target device with which the terminal device is associated may be the terminal device of the first user guardian. When the first user guardian wants to know the specific floor position of the first user, the target equipment can send an instruction to the terminal equipment of the first user, so that the terminal equipment can perform indoor positioning through the indoor positioning method in the embodiment of the invention.

The technical scheme can help the user or the guardian of the user to acquire the specific floor position of the user, and the user experience is enhanced.

102. And judging whether the first type of identification exists in the information of the N wireless local area networks.

In the embodiment of the invention, the first type identifier is used for representing that other users mark indoor floor information corresponding to the wireless local area network. That is, when the wireless lan has been marked by other users with corresponding indoor floor information, a first type of identification may be displayed, and the first type of identification may be a text identification or a graphic identification.

For example, when the first type of identifier is a text identifier, it may be denoted as "the network is marked.

When the first type of identifier is a graphic identifier, it may be denoted by "×", which is not limited by the embodiment of the present invention.

When a terminal device of another user (hereinafter, referred to as a "first terminal device") is connected to a certain wireless lan, the first terminal device issues a marking task to the other user, the other user may mark current indoor floor information after receiving the marking task, the first terminal device obtains the indoor floor information marked by the other user, and then sends the marked indoor floor information to a routing device, and the routing device stores the marked indoor floor information and the wireless lan correspondingly. When the user obtains the received information of the N wireless local area networks, the wireless local area networks marked with the indoor floor information corresponding to the wireless local area networks display the first type of identification.

The indoor floor information may include: floor information of the terminal equipment, or building information of the terminal equipment, and floor information of the building.

The floor information may be a name or a sign of a floor, and the building information may be a name or a sign of a building.

For example, when the user b sits in the store a of the third layer of the store a, the wireless local area network in the store a is connected, then the terminal device of the user b issues a marking task to the user b, after receiving the marking task, the user b marks the wireless local area network in the current store a on the terminal device, marks that the current wireless local area network is located at the third layer, or marks that the current wireless local area network is located at the third layer of the store a, then the terminal device sends the marked indoor floor information to the routing device, and the routing device stores the indoor floor information corresponding to the wireless local area network in the store a. When the terminal equipment of the user A is started up for the first time, and when the wireless local area network is searched, if the wireless local area network in the store A can be searched, the wireless local area network displays a graphical identifier, and the user A can know that the wireless local area network in the store A is the wireless local area network marked by other users with indoor floor information corresponding to the wireless local area network.

103. And acquiring target indoor floor information corresponding to the target wireless local area network.

In the embodiment of the invention, if the first type identifier exists in the information of M wireless local area networks in N wireless local area networks acquired by the terminal equipment, the terminal equipment can determine the wireless local area network with the received signal strength greater than the preset strength from the M wireless local area networks as a target wireless local area network, and acquire the target indoor floor information corresponding to the target wireless local area network, wherein the target indoor floor information specifically comprises the floor where the user is currently located. Wherein M is an integer greater than or equal to 1, and M is less than or equal to N.

For example, if the received signal strength of a wireless lan acquired by a terminal device is greater, it may be explained that the distance between an access point (e.g., may be a routing device) of the wireless lan and the terminal device is closer. The preset strength is set by the terminal equipment according to the relation between the received signal strength and the distance, so that the user can be connected with the wireless local area network closest to the terminal equipment, and the preset strength is-91 dBm, N is 10, and M is 5. After the terminal equipment of the user A is started up for the first time, when searching for the wireless local area networks, 10 wireless local area networks are searched, 5 wireless local area networks in the 10 wireless local area networks display a graphical identifier, namely the 5 wireless local area networks are marked by other users with indoor floor information corresponding to the wireless local area networks. At this time, the terminal device may detect the received signal strengths of the 5 wlans, to obtain the received signal strengths of the 5 wlans as-91.1 dBm, -94dBm, -90.1dBm, -92dBm, and-91.6 dBm, respectively, where-90.1 dBm is greater than-91 dBm. Then the wireless local area network with the received signal strength of-90.1 dBm can be determined as the target wireless local area network and the target indoor floor information corresponding to the target wireless local area network can be obtained.

104. And outputting the information of the floor in the target room.

The terminal device outputs the obtained information of the target indoor floor, and the specific output mode can be that the information is displayed on a display screen of the terminal device.

The embodiment of the invention provides an indoor positioning method, wherein a terminal device can determine a target wireless local area network which is marked with corresponding indoor floor information and has a received signal strength larger than a preset strength in a plurality of wireless local area networks, and acquire the indoor floor information corresponding to the target wireless local area network, so that the indoor floor information of the terminal device is obtained. According to the technical scheme, the terminal equipment which is started up for the first time does not need to acquire multiple air pressure values to compare so as to determine indoor floor information, the specific indoor floor can be directly determined through the marked indoor floor information in the wireless local area network, the received signal strength of which is greater than the preset strength and is searched by the current position, and the indoor floor information acquired by the terminal equipment is more accurate.

As an optional implementation manner, the acquiring the target indoor floor information corresponding to the target wireless local area network includes: judging whether a second type identifier exists in the information of the M wireless local area networks; if the second type of identification exists in the information of P wireless local area networks in the M wireless local area networks, determining a target wireless local area network from the P wireless local area networks, wherein P is an integer greater than or equal to 1, and P is less than or equal to M; and acquiring target indoor floor information corresponding to a target wireless local area network, wherein the target wireless local area network is specifically a wireless local area network with the received signal strength of more than preset strength in P wireless local area networks.

Wherein the second type of identification is used to mark that the wireless local area network has no security risk. That is, after the terminal device performs security detection on the wireless lan, if the wireless lan is secure, a second type of identifier may be displayed, where the second type of identifier may be a text identifier or a graphic identifier.

For example, when the second type of identifier is a text identifier, it may be denoted as "the network security".

When the second type of identifier is a graphic identifier, it may be represented as "#", which is not limited by the embodiment of the present invention.

It should be noted that, the wlan establishes connection in a wireless manner, but this transmission manner tends to have a great security problem. Generally, wireless local area networks employ security techniques including authentication, encryption, data integrity protection, and the like. The authentication comprises the following steps: when a user logs in a wireless local area network, the user needs to input a specific password or identity information for verification, such as inputting a mobile phone number to acquire a verification code, inputting an access password of the wireless local area network or checking the identity of the user by a specific mechanism and issuing a digital certificate bound with the identity information; the encryption includes: data encryption standard (Data Encryption Standard, DES), advanced encryption standard (Anvanced Encryption Standard, AES) and commercial block cipher algorithm (SM 4). The data integrity protection is to make the receiver able to determine exactly whether the received message is damaged in the form of insertion, tampering, reordering, etc. during the transmission process, and the perfect data integrity service can find whether the integrity is damaged or not, and can take some measure to recover from the integrity.

For example, if the received signal strength of a wireless lan acquired by a terminal device is greater, it may be explained that the distance between an access point of the wireless lan and the terminal device is closer. The preset strength is set by the terminal equipment according to the relation between the received signal strength and the distance, so that the user can be connected with the wireless local area network closest to the terminal equipment, and the preset strength is-91 dBm, M is 5 and P is 3. The terminal equipment judges whether the second type of identification exists in the information of the 5 wireless local area networks, if the terminal equipment detects that 3 wireless local area networks in the 5 wireless local area networks display "#" graphic identifications, namely the 3 wireless local area networks have no security risk. At this time, the terminal device may detect the received signal strengths of the 3 wlans, and obtain the received signal strengths of the 3 wlans as-94 dBm, -90.1dBm and-91.6 dBm, where-90.1 dBm is greater than-91 dBm, and then the terminal device may determine that the wlan with the received signal strength of-90.1 dBm is the target wlan and obtain the target indoor floor information corresponding to the target wlan.

The optional technical scheme also detects the safety of the wireless local area network, if the wireless local area network has no safety risk, the second type identifier is displayed so that the terminal equipment can acquire the indoor floor information from the wireless local area network with the second type identifier, and the safety and the stability of the terminal equipment are further ensured.

As an alternative implementation manner, after outputting the information of the floor in the target room, the terminal device may further issue a marking task to the user, so that the user marks the wireless local area network where the first type of identifier does not exist.

After the terminal device outputs the information of the target indoor floor, the user can obtain the current floor from the output information, and then the terminal device can issue a marking task to the user, so that the user marks the indoor floor information corresponding to the wireless local area network for the wireless local area network without the first type identifier in the information of the N wireless local area networks. When the name of the wireless local area network with the first type of identification does not exist, the terminal equipment can push route navigation to the store to the user according to the current position and the position of the store, so that the user can find the specific position of the wireless local area network and mark indoor floor information according to the route navigation pushed by the terminal equipment. When the name of the wireless local area network with the first type of identification does not exist, the terminal equipment can detect the received signal intensity of the wireless local area network and prompt a user to move in a small range, so that the terminal equipment can detect the specific direction of the wireless local area network according to the received signal intensity change when the user moves and prompt the user to move to the specific direction, and then detect the change of the received signal intensity in real time to prompt the user to advance until the received signal intensity of the wireless local area network is larger than the preset intensity, so that the user can find the specific position of the wireless local area network and mark indoor floor information according to the advance direction of the real-time push of the terminal equipment.

For example, after the terminal device outputs the target indoor floor information "the current wireless lan is located at the third floor of mall a", a marking task may be issued to the user. If there is no first type identifier in another wireless lan, it can be stated that the one wireless lan is not marked with the corresponding indoor floor information by other users, and then the user can mark the one wireless lan. If the name of the store B exists in the name of the wireless local area network, the wireless local area network can be described as belonging to the store B, and the terminal equipment can push route navigation to the store B to the user according to the current position and the store B, so that the user can find the specific position of the wireless local area network according to the route navigation and mark indoor floor information of the wireless local area network. If the name of the wireless local area network does not exist in the names of the shops, the terminal equipment can prompt the user to move to the surrounding, at the moment, the terminal equipment detects that the received signal strength of the wireless local area network becomes large when the user moves to the left, the terminal equipment can prompt the user to continuously move to the left and then continuously detect the received signal strength of the wireless local area network until the received signal strength of the wireless local area network is larger than the preset strength, the position of the wireless local area network can be indicated to be reached by the user, and at the moment, the terminal equipment can prompt the user to mark indoor floor information of the wireless local area network at the current position.

In this alternative implementation manner, after the user obtains the target indoor floor information, the terminal device may prompt the user to mark the indoor floor information on the wireless lan that is not marked. The method and the device can reduce the number of the wireless local area networks which are not marked, so that when terminal equipment which is started up for the first time of other users is used for indoor positioning, the probability of successful positioning is increased, and the user interaction experience is improved.

When a terminal device of another user (hereinafter, referred to as a "first terminal device") is connected to a certain wireless lan, the first terminal device issues a marking task to the other user, the other user may mark current indoor floor information after receiving the marking task, the first terminal device obtains the indoor floor information marked by the other user, and then sends the marked indoor floor information to a routing device, and the routing device stores the marked indoor floor information in correspondence with the wireless lan. The embodiment of the invention is suitable for the situation that the terminal equipment correspondingly stores the marked indoor floor information and the wireless local area network in the routing equipment of the wireless local area network.
