The location includes a floor and an in-floor location; therefore, the invention realizes double positioning in the horizontal direction and the vertical direction in the high-rise building.

The present invention will be described in further detail with reference to the accompanying drawings.

Drawings

Fig. 1 is a schematic structural diagram of an indoor navigation system of a high-rise building according to an embodiment of the present invention.

Detailed Description

The present invention will be described in further detail with reference to specific examples, but the embodiments of the present invention are not limited thereto.

In order to achieve dual positioning in the horizontal direction and the vertical direction in a high-rise building, an embodiment of the present invention provides a high-rise building indoor navigation system, as shown in fig. 1, including: a plurality of terminal nodes and servers; the terminal nodes are respectively positioned at a plurality of preset positions in a high-rise building room; these preset positions cover at least different floors of the high-rise building; the terminal nodes are all integrated with Bluetooth communication modules.

The server is used for sending a user searching instruction to all terminal nodes when receiving a navigation request sent by a user through a mobile phone; the navigation request and the search user instruction both carry a user identifier of the mobile phone, and the navigation request also carries a destination and authorization information that the bluetooth function of the mobile phone is started.

It will be appreciated that the server may communicate with the user's handset via the internet, a local area network and/or a mobile communications network. Thus, the server can receive the navigation request sent by the user.

Each terminal node is used for starting a Bluetooth function to search the mobile phone when receiving the search user instruction; when the mobile phone is searched and the strength of the signal sent by the mobile phone meets a preset threshold value, reporting the position of the mobile phone to the server; the locations include floors and floor locations.

It will be appreciated that the end node may communicate with the server via the internet, a local area network and/or a mobile communications network. That is, in addition to the bluetooth communication module, a communication module for communicating with the server is correspondingly integrated in the terminal node. Thus, even if the terminal node and the server are located on different floors, communication with the server is not possible without being affected by the communication distance.

And the server is used for generating a navigation line and feeding back the navigation line to the mobile phone of the user based on the position and the destination when receiving the position.

It can be understood that the server can correspondingly generate a navigation line to feed back to the mobile phone of the user by taking the received position as a starting point and the destination as an end point.

In the high-rise building indoor navigation system provided by the invention, a plurality of terminal nodes are distributed in a high-rise building; the terminal node can actively search the mobile phone of the user with the positioning requirement by starting the Bluetooth function; then, the terminal node can report the position of the terminal node to the server, so that the server generates a navigation line according to the position and a destination given by the user and returns the navigation line to the user. The location includes a floor and an in-floor location; therefore, the invention realizes double positioning in the horizontal direction and the vertical direction in the high-rise building.

Optionally, the server, when receiving the location, generates a navigation route based on the location and the destination, and feeds back the navigation route to the mobile phone of the user, including:

upon receipt of said location, determining a shortest route from a set of existing routes from said high-rise building that passes through both said location and said destination;

updating the shortest route by taking the position as a starting point and the destination as an important point to obtain a navigation route;

and feeding back the navigation line to the mobile phone of the user.

In the implementation mode, navigation can be realized by only pre-storing some line data as a line set without creating a graphical map.

Of course, the specific implementation manner of the server to generate the navigation route can also refer to the existing graphical map navigation manner, which is reasonable.

Optionally, the server is further configured to send a user search stopping instruction to all terminal nodes after the navigation line is fed back to the mobile phone of the user;

and each terminal node is also used for closing the Bluetooth function after receiving the search stopping user instruction.

It can be understood that the navigation is finished, the Bluetooth functions of all the terminal nodes are closed, the electric resource can be saved, and the endurance time of the terminal nodes is prolonged.

Optionally, in an implementation manner, the server is further configured to integrate all received locations when there is more than one terminal node sending a location.

It can be understood that when the terminal nodes are distributed densely in the high-rise building, more than one terminal node may possibly search for the mobile phone of the user; correspondingly, the server is subjected to the positions sent by the plurality of terminal nodes; at this time, the server may filter one position having the largest number of repetitions therefrom as a position used when the navigation route is finally generated. And when the distribution of the terminal nodes in the high-rise building is not very dense, the server integrates all the received positions, and the method may include:

and reserving the latest received position and rejecting the previously received position.

It will be appreciated that if the user lifts a navigation request in the vicinity of one end node and moves to the vicinity of the next end node shortly, the server will be subjected to the position from both end nodes; at this time, the server may use the received position of the mouth corner as the position used when the navigation route is finally generated.
