Fig. 1 is a schematic structural diagram of a navigation system in an enclosed space 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 a small-scale accurate positioning in an enclosed space, an embodiment of the present invention provides a navigation system in an enclosed space, as shown in fig. 1, including: a plurality of terminal devices and a server; the terminal devices are respectively positioned at a plurality of preset positions in the closed space; the terminal devices are integrated with Bluetooth communication modules; and the terminal equipment and the server realize communication through a wireless local area network or a communication cable.

The terminal device is used for responding to a navigation request sent by a user through mobile phone Bluetooth and sending a device identification of the terminal device, a Bluetooth name of the mobile phone and destination information carried in the navigation request to the server.

It will be appreciated that the bluetooth functionality of the terminal device is continuously on. Therefore, the navigation request sent by the user through the mobile phone Bluetooth can be received at any time.

The server is used for determining a navigation path based on the received equipment identification and the destination information, and feeding back the navigation path to the terminal equipment, so that the terminal equipment feeds back the navigation path to the mobile phone through a Bluetooth communication module integrated with the terminal equipment.

It will be appreciated that the server receives the device identification, i.e. can determine the approximate location of the user and use this as the user's starting location.

The server is further configured to determine at least two target terminal devices for assisting the navigation based on the navigation path, and notify the target terminal devices to search for the mobile phone corresponding to the bluetooth name.

It is understood that the target terminal device may search for a mobile phone corresponding to the bluetooth name, that is, search for the mobile phone of the user, by performing the bluetooth device discovery function.

The target terminal device is used for feeding back the search condition aiming at the mobile phone to the server in real time so that the server updates the user action track in the navigation path based on the search condition.

It is understood that the server monitors the action track of the user in the navigation path in real time through the target terminal devices.

Optionally, the search case includes at least: whether the condition of the mobile phone is searched and the RSSI value when the mobile phone is searched.

It can be understood that the condition of whether the mobile phone is searched or not can determine whether the mobile phone of the user is located in the range with which the target terminal device can perform bluetooth communication in real time, so that the action track of the user can be determined. And the distance between the target terminal equipment and the mobile phone of the user can be further determined by searching the RSSI value of the mobile phone, so that a more accurate action track of the user can be obtained.

Optionally, the server, based on the received device identifier and the destination information, generates a navigation path, including:

and generating a navigation path based on a preset building indoor map by taking a preset position corresponding to the equipment identifier as a starting point and the position indicated by the destination information as an end point.
