For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

The embodiment of the invention discloses a method and a system for sharing positioning data and a mobile terminal, which can enable a user of one mobile terminal to check specific indoor position information of a user of another mobile terminal at any time.

In order to better describe the method, the system and the mobile terminal for sharing the positioning data disclosed in the embodiments of the present invention, a description is first given of a system for sharing the positioning data applicable to the embodiments of the present invention. Referring to fig. 1, fig. 1 is a schematic structural diagram of a positioning data sharing system according to an embodiment of the present invention. As shown in fig. 1, the system for sharing the positioning data may include: the mobile terminal comprises a first mobile terminal, a second mobile terminal and a server. The first mobile terminal can be a mobile terminal such as a smart phone used by parents, the second mobile terminal can be a mobile terminal such as a smart watch used by children, and the server can establish communication connection with the first mobile terminal and the second mobile terminal through mobile communication networks such as 4G and 5G or wireless communication networks such as Wi-Fi. In addition, a Bluetooth communication connection can be established between the first mobile terminal and the second mobile terminal.

The following are detailed below.

Example one

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for sharing positioning data according to an embodiment of the present invention. The method for sharing the positioning data described in fig. 2 is suitable for mobile terminals such as smartwatches, smartphones, tablet computers, and home education machines, and the embodiment of the present invention is not limited thereto. The operating system of the mobile terminal may include, but is not limited to, an Android operating system, an IOS operating system, a Symbian operating system, a blackberry operating system, a Windows Phone8 operating system, and the like. As shown in fig. 2, the method for sharing positioning data may include the following steps:

101. when receiving a positioning sharing request sent by a first mobile terminal, a second mobile terminal judges whether the second mobile terminal is indoors or not; if yes, executing step 102; if not, the flow is ended.

In the embodiment of the present invention, the location sharing request sent by the first mobile terminal may be forwarded to the second mobile terminal by the server.

As an optional implementation manner, a satellite Positioning signal receiving module may be disposed in the second mobile terminal, where the satellite Positioning signal may be a signal sent by a Global Positioning System (GPS), a beidou satellite navigation System, or the like. The second mobile terminal can identify the satellite positioning signal strength received by a satellite positioning signal receiving module of the second mobile terminal when receiving the positioning sharing request sent by the first mobile terminal; if the received satellite positioning signal strength is lower than a preset satellite signal strength threshold, it can be determined that the second mobile terminal is indoors; if the received satellite positioning signal strength is not below the satellite signal strength threshold, the second mobile terminal may be deemed to be outdoors. Alternatively, the above-mentioned satellite signal strength threshold may be set with reference to an average value of satellite signal strengths received indoors by the mobile terminal. In the above-described embodiment, whether the second mobile terminal is indoors or not is determined based on the strength of the received satellite positioning signal, using the characteristic that the satellite positioning signal is weak in penetration and is difficult to receive indoors.

As another alternative, an ultraviolet sensor may be disposed in the second mobile terminal. Judging whether the ultraviolet intensity received by the ultraviolet of the second mobile terminal is lower than a preset ultraviolet intensity threshold value or not; if yes, the second mobile terminal can be judged to be indoors; if not, it can be determined that the second mobile terminal is outdoors. Alternatively, the above-mentioned ultraviolet intensity threshold may be set with reference to an average value of ultraviolet intensities received by the ultraviolet sensor indoors. In the above embodiment, by using the characteristic that the ultraviolet intensity is different between the indoor and outdoor, whether the second mobile terminal is indoors can be determined by the received ultraviolet intensity.

As a further alternative, the data collected by the ultraviolet sensor and the satellite positioning signal receiving module may be fused to determine whether the second mobile terminal is indoors. The method specifically comprises the following steps: judging whether the ultraviolet intensity received by an ultraviolet sensor of the second mobile terminal is lower than a preset ultraviolet intensity threshold value or not; if so, judging whether the satellite positioning signal strength received by a satellite positioning signal receiving module of the second mobile terminal is lower than a preset satellite signal strength threshold value or not; if the received ultraviolet intensity is judged to be lower than the ultraviolet intensity threshold value and the received satellite positioning signal intensity is judged to be lower than the satellite signal intensity threshold value, the second mobile terminal is judged to be indoors; if the received ultraviolet intensity is judged not to be lower than the ultraviolet intensity threshold value, the second mobile terminal is judged to be located outdoors; and if the received ultraviolet intensity is judged to be lower than the ultraviolet intensity threshold value and the received satellite positioning signal intensity is not lower than the satellite signal intensity threshold value, judging that the second mobile terminal is located outdoors. If the current weather is cloudy or the second mobile terminal is located in a space (such as a bottom floor of a building) which is reserved for pedestrians at the edge of the building, the intensity of the ultraviolet rays received by the ultraviolet ray sensor may be weak, but the second mobile terminal is not located indoors actually. Therefore, when the above-described embodiment is implemented, if it is determined that the ultraviolet intensity is weak, the intensity of the satellite positioning signal is further used to perform a secondary determination, so as to improve the accuracy of determining whether the second mobile terminal is indoors.

102. The second mobile terminal identifies the building information of the target building where the second mobile terminal is located at present, and detects the instant air pressure value by using the air pressure sensors of the second mobile terminal.

In the embodiment of the present invention, as an optional implementation manner, when the second mobile terminal receives the satellite positioning signal of which the signal intensity is not lower than the satellite signal intensity threshold value for the last time, the position determined by the satellite positioning signal may be identified as the satellite signal vanishing point position, and in combination with the information of the surrounding buildings provided by the electronic map, the building where the satellite signal vanishing point position is located may be determined as the target building where the second mobile terminal is currently located.

103. And when the second mobile terminal detects that the change of the instant air pressure value is stable, determining the floor information of the target floor where the second mobile terminal is located according to the instant air pressure value.

In the embodiment of the present invention, the second mobile terminal may collect the air pressure according to a preset frequency. If the instant air pressure value acquired for N consecutive times (N is a positive integer) is not changed, or the difference value is lower than a preset threshold value, the change of the instant air pressure value can be considered to be stable. At this time, the height difference between the floor where the second mobile terminal is currently located and the reference floor corresponding to the reference air pressure value can be determined according to the difference between the instant air pressure value and the preset reference air pressure value, and the target floor where the second mobile terminal is currently located can be determined based on the height difference, the preset inter-floor distance and the floor number of the reference floor.

104. And the second mobile terminal determines the position information of the second mobile terminal in the target floor according to the wireless communication signal received by the second mobile terminal.

In the embodiment of the present invention, the wireless communication signal may be a Wi-Fi signal, a bluetooth signal, an Ultra Wideband (UWB) signal, or the like. The wireless communication signal received by the second mobile terminal may be transmitted by a wireless communication signal transmitter disposed within the target floor, for example, the wireless communication signal transmitter may be a wireless router within a store.

Because the strength of the received wireless communication signal is inversely proportional to the distance, the distance between the second mobile terminal and the wireless communication signal transmitter can be determined according to the strength of the received wireless communication signal, and the position of the wireless communication signal transmitter in the target floor is known, so that the position of the second mobile terminal in the target floor can be determined based on the principle of triangulation positioning.

105. The second mobile terminal sends the building information of the target building, the floor information of the target floor and the position information of the second mobile terminal in the target floor to the first mobile terminal.

In the embodiment of the present invention, the building information of the target building may include at least a name of the target building, the floor information of the target floor may include at least a name of the target floor, a height from the ground of the target floor, and the location information of the second mobile terminal within the target building may include a specific position of the location within the target building or a name of a unit (such as a store or an office) within the target building closest to the location. The second mobile terminal may specifically send the information to the first mobile terminal through the server.

For example, the information transmitted by the second mobile terminal to the first mobile terminal may be "the kth cell (position within the target floor) currently located at mth floor (target floor) of building B2 a (target floor)". Therefore, the user of the first mobile terminal can check the specific position of the user of the second mobile terminal in the room.

In addition, as an optional implementation manner, the second mobile terminal may identify the geographic location of the first mobile terminal carried in the location sharing request, so as to determine the geographic area where the first mobile terminal is located; if the target building where the second mobile terminal is located is identified, the geographical area where the target building is located can be further identified; if the geographical area of the target building is different from the geographical area of the first mobile terminal, the second mobile terminal can send the geographical area of the target building besides sending the building information of the target building, the floor information of the target floor and the position information of the second mobile terminal in the target floor, so that the first mobile terminal can also output the geographical area of the target building. When the geographic regions are different, the possibility of the homonymous buildings is increased, and at the moment, the first mobile terminal outputs the geographic region where the target building is located, so that the interference of the homonymous buildings can be reduced, and the user of the first mobile terminal can more accurately determine the position of the user of the second mobile terminal.

As another alternative, the server may be a server of an emergency rescue system such as an alarm center, an emergency center, etc., the second mobile terminal may be a mobile terminal used by a rescuer, and the first mobile terminal may be a mobile terminal used by a rescuer (such as a fireman, a medical staff, etc.). The second mobile terminal can send a distress signal to the server, and after receiving the distress signal, the server distributes the rescuers executing the rescue task and sends the rescue task to the first mobile terminal used by the rescuers executing the rescue task. After receiving the rescue task, the first mobile terminal may send a location sharing request to the second mobile terminal to trigger the second mobile terminal to execute the method shown in fig. 2, so that the rescuer may view the specific location of the rescuer through the first mobile terminal. By implementing the implementation mode, the help seeker who can not independently complete help seeking in sudden critical diseases or in dangerous situations and the like can be helped to send the specific position of the help seeker, so that the rescue time is saved, and the success rate of rescue is improved.

It can be seen that, with the method described in fig. 2, after receiving the location sharing request sent by the first mobile terminal, the second mobile terminal accurately locates the specific indoor location of the second mobile terminal by building location, floor location, and intra-floor location, and sends the specific indoor location to the first mobile terminal, so that the user of the first mobile terminal can view the specific indoor location of the user of the second mobile terminal by sending the location sharing request at any time.

Example two

Referring to fig. 3, fig. 3 is a schematic flow chart illustrating another positioning data sharing method according to an embodiment of the present invention. As shown in fig. 3, the method for sharing positioning data may include the following steps:

201. when receiving a positioning sharing request sent by a first mobile terminal, a second mobile terminal judges whether the second mobile terminal is indoors or not; if yes, executing step 202 to step 205; if not, step 206 to step 208 are executed.

202. The second mobile terminal identifies the building information of the target building where the second mobile terminal is located at present, and detects the instant air pressure value by using the air pressure sensors of the second mobile terminal.

203. And when the second mobile terminal detects that the change of the instant air pressure value is stable, determining the floor information of the target floor where the second mobile terminal is located according to the instant air pressure value.

204. And the second mobile terminal determines the position information of the second mobile terminal in the target floor according to the wireless communication signal received by the second mobile terminal.

In an embodiment of the present invention, the wireless communication signal received by the second mobile terminal may be transmitted by a wireless communication signal transmitter disposed in the target floor.

205. The second mobile terminal sends the building information of the target building, the floor information of the target floor and the position information of the second mobile terminal in the target floor to the first mobile terminal.

206. And the second mobile terminal determines the real-time position of the second mobile terminal according to the satellite positioning signal and/or the mobile communication signal received by the second mobile terminal.

In the embodiment of the present invention, when the second mobile terminal is located outdoors (i.e., not located indoors), the real-time position of the second mobile terminal may be determined by performing satellite positioning through a satellite positioning signal, performing base station positioning through a mobile communication signal, or combining the results of the satellite positioning and the base station positioning.

207. And the second mobile terminal determines the moving speed of the second mobile terminal according to the change of the real-time position of the second mobile terminal.

In the embodiment of the invention, the moving distance of the second mobile terminal can be determined through the change of the real-time position of the second mobile terminal, and the moving speed of the second mobile terminal can be determined according to the moving distance and the moving time.

208. The second mobile terminal judges whether the moving speed of the second mobile terminal is within a moving speed range corresponding to any preset travel mode; if yes, go to step 209; if not, the flow is ended.

In the embodiment of the present invention, the preset travel modes may include, but are not limited to: walking, running and riding. The movement speed ranges corresponding to different travel modes are different, for example, the movement speed range corresponding to walking can be less than 4 km/h, the movement speed range corresponding to running can be 5 km/h-10 km/h, and the movement speed range corresponding to riding can be 25 km/h-60 km/h.

209. And the second mobile terminal sends the real-time position and the travel mode of the second mobile terminal to the first mobile terminal.

In the embodiment of the invention, when the second mobile terminal is located outdoors, the user of the first mobile terminal can check the real-time position of the user of the second mobile terminal and also can check which travel mode the user of the second mobile terminal adopts for traveling, so that parents can be helped to judge whether the currently selected travel mode of the child is safe or not, and corresponding precautionary measures can be taken in time.

It can be seen that, as shown in fig. 3, when the second mobile terminal is located indoors, the user of the first mobile terminal can view the specific location of the user of the second mobile terminal indoors; when the second mobile terminal is located outdoors, the user of the first mobile terminal can view the travel mode and the real-time position of the user of the second mobile terminal outdoors, so that the first mobile terminal can view the position of the second mobile terminal whether indoors or outdoors.

In the embodiment of the invention, the effective connection range of the Bluetooth communication between the mobile terminals is generally within 10 meters, so the Bluetooth can be applied to the loss prevention detection. When a disconnection of the bluetooth communication connection is detected, the distance between the first mobile terminal and the second mobile terminal may exceed 10 meters. If the first mobile terminal is a parent's smart phone and the second mobile terminal is a child's smart watch, the distance between the child and the parent may exceed the sight range, and the child is easily lost.

302. The second mobile terminal judges whether the second mobile terminal is carried on a human body; if yes, go to step 303; if not, the flow is ended.

Generally, a user will start the bluetooth anti-loss function during moving, and therefore will not be in a stationary state within a preset time period, and if the second mobile terminal is carried on a human body, a motion sensor (such as an accelerometer, a gyroscope, etc.) of the second mobile terminal may detect an action of the human body.

As another optional implementation, the second mobile terminal may specifically be a wearable device such as a smart watch and a smart band. When the second mobile terminal is a wearable device, the specific implementation of determining whether the second mobile terminal is carried on a human body may include the following steps: detecting whether a vital sign sensor of a second mobile terminal detects a vital sign of a human body; if yes, the second mobile terminal is carried on the human body.

Further, if the first mobile terminal is located indoors, the real-time location data of the first mobile terminal may further include a building where the first mobile terminal is currently located, a floor where the first mobile terminal is currently located, and a specific location within the floor where the first mobile terminal is currently located. The manner in which the first mobile terminal determines the building, the floor, and the specific location within the floor where the first mobile terminal is currently located may be the same as that of the second mobile terminal, and details are not repeated below.

304. The second mobile terminal judges whether the second mobile terminal is indoors or not; if so, go to step 305; if not, the flow is ended.

In this embodiment of the present invention, the second mobile terminal may further execute step 304 after receiving the location sharing request sent by the first mobile terminal.
