In the figure, the solid line represents the implementation flow of the mobile terminal and the target bluetooth device, and the dotted line represents the implementation flow of the interaction between the mobile terminal and the target bluetooth device.
According to fig. 1, the method comprises the following steps:
step S1010, performing bluetooth scanning by the target bluetooth device to obtain bluetooth information broadcasted by at least one relay bluetooth device.
The Bluetooth information at least comprises an identification code of the relay Bluetooth device and a Bluetooth signal strength value between the relay Bluetooth device and the target Bluetooth device.
The relay bluetooth device is specifically a bluetooth device that is around the target bluetooth device and the target bluetooth device can scan its broadcast.
Bluetooth devices are typically only in a broadcast state or a scan state and cannot scan while broadcasting. Therefore, the target bluetooth device may stop broadcasting and start bluetooth scanning if it receives a specific command in the broadcasting state. The specific instruction may be, for example, but not limited to, an instruction to reserve use of the target bluetooth device, an instruction to locate the target bluetooth device, and the like. The specific instruction may be transmitted to the target bluetooth device by the mobile terminal according to the location information of the target bluetooth device.
Fig. 2 is a flow chart of another embodiment of a method for locating a target bluetooth device in accordance with the present invention.
Before performing step S1010, the method further includes steps S2010 to S2040 as shown in fig. 2. In the figure, the solid line represents the respective implementation flows of the mobile terminal, the target bluetooth device and the server, and the dotted line represents the implementation flows of the interaction between the mobile terminal and the target bluetooth device and between the mobile terminal and the server.
In step S2010, the target bluetooth device acquires its own location information.
In step S2020, the target bluetooth device transmits its own location information, so that the mobile terminal receives the location information of the target bluetooth device.
In step S2030, the mobile terminal receives the location information of the target bluetooth device.
Step S2040, the mobile terminal displays the location information of the target bluetooth device for the user to locate the target bluetooth device.
The position information of the target bluetooth device itself may be obtained through a positioning module arranged in the target bluetooth device, and the positioning module may be any one or any combination of a GPS positioning module, a beidou positioning module, a galileo positioning module, and a base station positioning module, for example. The position information acquired by the positioning module has certain error, but the user can position the target Bluetooth device in an approximate position range by referring to the position information and then accurately position the target Bluetooth device by the method. The location information of the target bluetooth device displayed by the mobile terminal may be, for example, an identification point displayed on a bluetooth device map.
Further, the target bluetooth device may directly send the position information of the target bluetooth device to the mobile terminal, or the target bluetooth device may send the position information of the target bluetooth device to the server, and the server sends the position information of the target bluetooth device to the mobile terminal.
On the basis, the mobile terminal can send a specific instruction aiming at the position information of the target Bluetooth device to the server, the server can send the specific instruction to the target Bluetooth device, and the server can process the specific instruction and then send the processed specific instruction to the target Bluetooth device.
In step S1020, the target bluetooth device transmits the bluetooth information broadcast by the relay bluetooth device.
Specifically, the target bluetooth device may directly send all or part of the bluetooth information of the relay bluetooth device to the mobile terminal; the target Bluetooth device can also send all or part of the Bluetooth information of the relay Bluetooth device to the server, and then the server sends the received all or part of the Bluetooth information of the relay Bluetooth device to the mobile terminal; the target Bluetooth device can also send all or part of the Bluetooth information of the relay Bluetooth devices to the server, and the server screens out part of the Bluetooth information of the relay Bluetooth devices meeting preset conditions and sends the part of the Bluetooth information of the relay Bluetooth devices meeting the preset conditions to the mobile terminal.
If the server selects the bluetooth information of part of the relay bluetooth devices meeting the preset condition from the received bluetooth information of all or part of the relay bluetooth devices, the bluetooth information may be specifically selected according to the bluetooth signal strength value between the relay bluetooth device and the target bluetooth device.
Step S1030, the mobile terminal acquires the identification code of the target bluetooth device.
The method for the mobile terminal to acquire the identification code of the target bluetooth device may be that the user inputs the identification code into the mobile terminal, and specifically, the identification code may be input through a keyboard application in the mobile terminal.
The mobile terminal may acquire the identification code of the target bluetooth device from the server. Then, the step S1030 may further include steps S1031 to S1036 as shown in fig. 2.
And step S1031, the mobile terminal acquires the position information of the target Bluetooth device selected by the user.
For example, a bluetooth device map displayed by the mobile terminal has a plurality of identification points representing the locations of bluetooth devices, and a user can obtain location information of a target bluetooth device corresponding to a certain identification point by selecting the identification point.
Step S1032, the mobile terminal sends the location information of the target bluetooth device to the server.
In step S1033, the server receives the location information of the target bluetooth device.
In step S1034, the server may determine the identification code of the target bluetooth device according to the location information of the target bluetooth device.
Specifically, the server may store in advance identification codes of the bluetooth devices and position information thereof, and a one-to-one mapping relationship is provided between the identification code of each bluetooth device and the position information thereof.
Further, the server may search a comparison table reflecting the location information of the bluetooth device and the identification code of the bluetooth device, and determine the identification code of the target bluetooth device corresponding to the location information of the target bluetooth device.
In step S1035, the server sends the identification code of the target bluetooth device to the mobile terminal.
In step S1036, the mobile terminal receives the identification code of the target bluetooth device.
Thus, the mobile terminal can acquire the identification code of the target Bluetooth device.
And step S1040, the mobile terminal receives all or part of the Bluetooth information of the relay Bluetooth device.
The bluetooth information of all or part of the relay bluetooth devices received by the mobile terminal may be sent by the target bluetooth device or sent by the server.
Step S1050, the target bluetooth device broadcasts its own identification code through bluetooth.
Specifically, the target bluetooth device may be automatically switched to a broadcast state after scanning for a set time, and the broadcast information includes its own identification code, so as to be conveniently found by a user using the mobile terminal.
In step S1060, the mobile terminal continuously scans the current broadcast data through bluetooth to obtain a bluetooth device list.
The mobile terminal may continuously scan for current broadcast data in response to a user request to turn on the bluetooth function. The current broadcast data is the Bluetooth broadcast data scanned by the mobile terminal at the current moment. The bluetooth device list at least includes an identification code of the bluetooth device broadcasting each current broadcast data, wherein each current broadcast data may include an identification code broadcasting the corresponding bluetooth device.
Further, the bluetooth device list is updated in real time according to the scanning frequency of the mobile terminal, and the updating frequency may be the same as the scanning frequency of the mobile terminal.
Step S1070, the mobile terminal judges whether the Bluetooth device list has the identification code of at least one Bluetooth device matched with the identification code of at least one relay Bluetooth device included in the received Bluetooth information of all or part of relay Bluetooth devices, if so, step S1080 is executed; if not, the process continues to step S1060.
And step S1080, displaying the matched identification code and the real-time signal strength between the matched relay Bluetooth device and the mobile terminal by the mobile terminal so as to guide the user to approach the matched relay Bluetooth device.
When the Bluetooth device list has the identification code of at least one Bluetooth device matched with the identification code of at least one relay Bluetooth device included in the received Bluetooth information of the relay Bluetooth device, the mobile terminal is closer to the matched relay Bluetooth device, and the mobile terminal can scan the broadcast of the matched relay Bluetooth device, so that the user can be guided to approach the matched relay Bluetooth device according to the signal intensity between the mobile terminal and the matched relay Bluetooth device. Specifically, the user is required to carry the mobile terminal to move in the direction in which the signal strength between the mobile terminal and the matched relay bluetooth device is increased, which indicates that the user is close to the matched relay bluetooth device.
Further, the mobile terminal displays the matched identification code and the real-time signal strength between the matched relay Bluetooth device and the mobile terminal according to the size sequence of the Bluetooth signal strength between the matched relay Bluetooth device and the target Bluetooth device.
For example, when there are at least two matched bluetooth relay devices, the identifier of the matched bluetooth relay device having a larger signal strength value with the target bluetooth device and the real-time signal strength between the mobile terminal and the bluetooth relay device are displayed at a position above the display interface of the mobile terminal, and the identifier of the matched bluetooth relay device having a smaller signal strength value with the target bluetooth device and the real-time signal strength between the mobile terminal and the bluetooth relay device are displayed at a position below the display interface of the mobile terminal. Since the larger the signal strength value between the matched relay bluetooth device and the target bluetooth device is, the closer the distance between the matched relay bluetooth device and the target bluetooth device is, the easier the target bluetooth device is located according to the matched relay bluetooth device, therefore, the user can find the target bluetooth device more quickly through the display mode of the embodiment.
Step S1090, the mobile terminal judges whether the Bluetooth device list comprises the identification code of the target Bluetooth device, if so, step S1100 is executed; if not, the process continues to step S1060.
Step S1100, the mobile terminal displays the identification code of the target Bluetooth device and the real-time signal intensity between the target Bluetooth device and the mobile terminal so as to guide the user to locate the target Bluetooth device.
Because the target Bluetooth device can scan the broadcast of the relay Bluetooth device, when the user is located at the position of the relay Bluetooth device, the mobile terminal can scan the broadcast of the target Bluetooth device, and then the user can be guided to approach the target Bluetooth device according to the signal intensity between the mobile terminal and the target Bluetooth device to locate the target Bluetooth device.
If the Bluetooth device list acquired by the mobile terminal comprises the identification code of the target Bluetooth device in the process that the user approaches the matched relay Bluetooth device, the fact that the distance between the mobile terminal and the target Bluetooth device is short is indicated, the mobile terminal can scan the broadcast of the target Bluetooth device, the relay Bluetooth device does not need to be located, and the user can be guided to approach the target Bluetooth device and the target Bluetooth device can be located directly according to the signal intensity between the mobile terminal and the target Bluetooth device.
By the method, when the mobile terminal is not in the broadcasting range of the target Bluetooth equipment, the target Bluetooth equipment can be positioned by the relay Bluetooth equipment, so that the searching range of the positioned target Bluetooth equipment can be expanded, and a user can more easily position the target Bluetooth equipment.
< example >
When the target bluetooth device is a target shared object, the relay bluetooth device may be a shared object or a bluetooth device such as a bluetooth spud.
When the target shared object receives a reservation request sent by a user through a mobile terminal, the target shared object starts Bluetooth scanning to obtain Bluetooth information broadcasted by at least one relay Bluetooth device and sends the Bluetooth information so that the mobile terminal reserving the target shared object receives all or part of the Bluetooth information of the relay Bluetooth device. The Bluetooth information at least comprises an identification code of the relay Bluetooth device and a Bluetooth signal strength value between the relay Bluetooth device and the target shared object.
The reservation request sent by the mobile terminal to the target shared article may be directly sent to the target shared article, may be directly sent to the target shared article after being transferred by the server, or may be a command generated according to the reservation request sent by the server to the target shared article.
The target shared object can be a Bluetooth broadcast function which is started after the set time is scanned, and the identification code of the target shared object is broadcasted.
When the mobile terminal sends out a reservation request, the identification code of the target shared object can be obtained from the server according to the address information of the target shared object, the identification code and the address information of the shared object are stored in the server, a one-to-one mapping relation exists between the identification code and the address information of each shared object, and the identification code of the target shared object can be uniquely determined according to the address information of the target shared object. The position information of the shared article stored in the server can be acquired by positioning modules such as a GPS positioning module, a Beidou positioning module, a Galileo positioning module and a base station positioning module which are arranged in the shared article and sent to the server.
The server can display the position information of each shared article on the shared article map and provide the position information to the mobile terminal for the user to view.
The mobile terminal may issue a reservation request to the target shared item according to the location information of the shared item on the shared item map.
Further, the server can also determine the comprehensive position information of the target shared object according to all or part of the Bluetooth information of the relay Bluetooth device and the position information of the target shared object sent by the target shared object, update the comprehensive position information of the target shared object to a shared object map, and provide the comprehensive position information to the mobile terminal. Specifically, under the condition that the relay bluetooth device is a shared object or a bluetooth spud, the server may pre-store the location information of each relay bluetooth device, and may determine the comprehensive location information of the target bluetooth device according to the location information of the relay bluetooth device, the location information of the target shared object, and the bluetooth signal strength value between each relay bluetooth device and the target bluetooth device. The step of determining the comprehensive position information can also be executed in the mobile terminal, and the preferable scheme is executed in the server, so that the algorithm can be updated and iterated more conveniently and quickly, the application version used by the user is not required, the user does not need to update, and the user experience can be improved.
