Watch 1

Optionally, the terminal always generates connection records, and each connection record corresponds to: record time, bluetooth connection status, and real-time geographic location.

And step 206, carrying out Bluetooth positioning on the target equipment according to the connection record.

When the target equipment needs to be subjected to Bluetooth positioning, the terminal acquires the historical appearance position of the target equipment through the connection record of the historical record, and then performs Bluetooth positioning on the target equipment at the historical appearance position which may exist in the target equipment.

In summary, in the method for positioning a device provided in the embodiment of the present invention, the real-time geographic location and the bluetooth connection state of the target device are recorded to obtain the corresponding connection record, and the target device is bluetooth-positioned according to the connection record; the problem that the user cannot perform Bluetooth positioning when not knowing the approximate position of the Bluetooth anti-lost device is solved; the effect of acquiring the approximate position of the target equipment according to the connection records of the history records is achieved, and therefore the target equipment can be positioned in a Bluetooth mode.

Referring to fig. 3, a flowchart of a method for locating a device according to another embodiment of the present invention is shown. The embodiment is exemplified by applying the method of the positioning device to the terminal 120. The method comprises the following steps:

step 301, acquiring real-time geographic position and Bluetooth connection state of a target device at regular time, wherein the Bluetooth connection state comprises a connection state and a disconnection state;

due to the binding relationship between the terminal and the target device, the terminal and the target device can keep the Bluetooth connection state for a long time. However, when the target device is far away from the terminal, the bluetooth connection between the terminal and the target device is disconnected.

The terminal acquires the real-time geographic position of the terminal and the Bluetooth connection state of the target device at preset time intervals, such as once every 5 seconds or once every 30 seconds.

The predetermined time interval may be set by a user.

The bluetooth connection state includes an in-connection state and a disconnection state.

Step 302, generating a connection record corresponding to the target device according to the geographic position and the Bluetooth connection state;

and the terminal generates a connection record corresponding to the target equipment according to the geographical position and the Bluetooth connection state acquired each time.

Each connection record corresponds to: record time, bluetooth connection status, and real-time geographic location.

Step 303, displaying the historical track of the target device on a map according to the connection record;

when receiving a viewing instruction sent by a user, the terminal may display a history track of the target device on the map according to the connection record. Optionally, the historical track is represented using a number of indicator tags.

The terminal selects the latest n connection records, generates each connection record as an indication label on the map, and uses the number i to represent that the connection record corresponding to the indication label is the ith connection record from the latest to the latest, or the ith connection record from the latest to the latest.

As shown in fig. 4, the terminal selects the last 6 connection records, each of which generates an indication tag 40 located on the map. The number i on the indication label 40 is used for the connection record corresponding to the indication label, which is the latest to the i-th connection record.

The location on the map pointed to by each indicator tag 40 is the geographic location in the connection record.

Each indicator tab 40 may be selected by a user. When one of the indication labels 40 is selected, the terminal may further display the recording time and the geographical position in the text form in the connection record corresponding to the indication label 40 under the map so as to be in connection record corresponding to the indication label 40.

Indicator tag 40 may also use a different color to indicate the bluetooth connection status in the corresponding connection record. For example, when the indication tag 40 adopts the first tag, it indicates that the bluetooth connection state in the corresponding connection record is the connection-in state; when the second tag is used as the instruction tag 40, it indicates that the bluetooth connection state in the corresponding connection record is a disconnected state.

For example, after the 6 th indicator tab in fig. 4 is selected, the "2015 year 6 month 30 day 10:11: 30 ' and ' Hangzhou city western lake area Jiang village xi Ling national wetland park north '.

Step 304, receiving a Bluetooth broadcast message in a current area when receiving a positioning instruction triggered according to a historical track;

the user can check each connection record in the history track, and when the user checks the latest connection record that the Bluetooth connection state is the connection state. The geographical location in the connection record is the geographical location where the target device last appeared.

Then, the user judges whether the current geographic position of the user belongs to the same area as the geographic position of the target device when the user appears for the last time, if the current geographic position of the user belongs to the same area, the Bluetooth positioning function is directly started, and the target device is positioned in a Bluetooth mode; if the terminal does not belong to the same area, the user can move the terminal to the geographical position of the last occurrence and then start the Bluetooth positioning function to perform Bluetooth positioning on the target equipment.

And 305, performing Bluetooth positioning on the target equipment according to the received Bluetooth broadcast message.

The target device sends a Bluetooth broadcast message to the outside periodically, wherein the Bluetooth broadcast message carries a first identifier of the target device. The first identification is an identification adopted by the device when identifying the identity of the device in the Bluetooth broadcast message. Optionally, the first identifier includes: a protocol name and a MAC (Media Access Control) address. Optionally, the protocol name is "QQ association".

Optionally, the terminal performs bluetooth positioning on the target device according to the received bluetooth broadcast message, including the following steps:

firstly, a terminal detects whether a first identifier carried by a received Bluetooth broadcast message is a first identifier of a target device;

secondly, if the first identification is the first identification of the target equipment, establishing Bluetooth connection with equipment for sending the Bluetooth broadcast message, and acquiring a second identification of the equipment through the Bluetooth connection;

since different devices may have the same first identifier, even if the first identifier in the bluetooth broadcast message is the first identifier of the target device, the device sending the bluetooth broadcast message is not represented as the target device.

Therefore, after the terminal establishes the bluetooth connection with the device sending the bluetooth broadcast message, the terminal acquires the second identifier from the device.

Thirdly, detecting whether the second identifier is the second identifier of the target device;

fourthly, if the second identification is the second identification of the target equipment, the current geographic position is determined to be the position of the target equipment.

Fifthly, if the second identifier is not the second identifier of the target device, the second identifier is discarded.

Optionally, after confirming that the first identifier is the first identifier of the target device, the terminal displays the bluetooth broadcast message or the signal strength of the bluetooth connection in real time. The signal strength may direct the user to move the terminal in a direction in which the signal strength becomes higher.

Optionally, after the bluetooth connection is successfully established, the terminal further displays a reminder button. When the reminding button is pressed, the terminal sends a reminding instruction to the target equipment through the Bluetooth connection, and the reminding instruction is used for indicating the target equipment to carry out at least one of vibration reminding, ring reminding and light reminding.

As shown in fig. 5, the terminal may display a numerical value 52 on the signal strength on the user interface 50. When the user terminal is present, the value will change accordingly. The user can move the terminal toward a direction in which the signal strength becomes high, thereby finding the target device.

The terminal may also display a virtual reminder button 54 on the user interface 50, the reminder button 54 being non-clickable when a bluetooth connection is not successfully established; the reminder button 54 becomes clickable upon successful establishment of a bluetooth connection. If the user clicks the prompt button 54, the terminal sends a prompt instruction to the target device through the bluetooth connection, and the target device sends out a buzzer sound after receiving the prompt instruction.

In summary, the method for positioning a device according to this embodiment obtains a corresponding connection record by recording a real-time geographic location and a bluetooth connection state of a target device, and performs bluetooth positioning on the target device according to the connection record; the problem that the user cannot perform Bluetooth positioning when not knowing the approximate position of the Bluetooth anti-lost device is solved; the effect of acquiring the approximate position of the target equipment according to the connection records of the history records is achieved, and therefore the target equipment can be positioned in a Bluetooth mode.

The embodiment also realizes the effect that the user can search the target device according to the signal intensity by displaying the Bluetooth broadcast message or the signal intensity of the Bluetooth connection in real time.

In this embodiment, by providing the reminding button, after the terminal is physically connected to the target device, the target device makes a sound, vibration or light reminding, so that the user can find the target device more easily.

Referring to fig. 6, a flowchart of a method for locating a device according to another embodiment of the invention is shown. The embodiment is exemplified by applying the method of the positioning device to the terminal 120. The method comprises the following steps:

step 601, acquiring real-time geographic position and Bluetooth connection state of target equipment at regular time, wherein the Bluetooth connection state comprises a connection state and a disconnection state;

The predetermined time interval may be set by a user.

Step 602, generating a connection record corresponding to the target device according to the geographic position and the bluetooth connection state;

Step 603, acquiring the latest connection record of which the Bluetooth connection state is the connection state;

when the target device needs to be positioned, the terminal acquires the latest connection record of which the Bluetooth connection state is the connection state from the plurality of connection records of the history records.

For example, the third connection record in table one is the last connection record of "the bluetooth connection state is the connection state".

Step 604, reading the geographical position in the last connection record;

and after the last connection record that the Bluetooth connection state is the connection state is acquired, the terminal reads the geographical position in the last connection record. The geographical location is the last occurrence of the target device recorded by the terminal.

Step 605, detecting whether the distance between the read geographical position and the current geographical position is smaller than a preset distance;

the preset threshold is usually set by the receiving distance of the bluetooth broadcast message, for example, 50 meters.

That is, if the value is smaller than the preset threshold, the terminal can perform short-range bluetooth positioning on the target device, and then the process goes to step 606.

If the current position is not less than the preset threshold value, the terminal may not be able to successfully perform short-range bluetooth positioning even if the target device is at the last-occurring position at the time. At this point, the terminal may enable remote bluetooth positioning, proceeding to step 608.

Step 606, receiving the bluetooth broadcast message in the current area if the distance is less than the receiving distance of the bluetooth broadcast message;

step 607, performing bluetooth positioning on the target device according to the received bluetooth broadcast message.

This step is the same as or similar to step 305, and is not described again in this embodiment.

Step 608, if the distance is greater than the preset distance, a positioning request carrying the read geographic location and the first identifier of the target device is generated.

The first identification is an identification adopted when the equipment identifies the identity of the equipment in the Bluetooth broadcast message;

if the distance is greater than the preset distance, the terminal is likely to be unable to perform bluetooth positioning on the target device smoothly. The terminal needs to start remote bluetooth positioning, and at this time, the terminal generates a positioning request.

The location request carries: a first identification of the target device, and a geographical location read by the terminal from the last connection record.

Optionally, the positioning request further carries: and searching for the distance. The search distance may be set manually by the user, such as 200 meters, 500 meters, or 1 kilometer.

Step 609, sending the positioning request to the server so that the server sends a positioning instruction to at least one other device located in the area where the geographic position is located, wherein the positioning instruction is used for instructing the other device to perform bluetooth positioning on the target device.

The terminal sends the positioning request to the server.

The server obtains the geographic position and the search distance in the positioning request, and determines the target area by taking the geographic position as the center and the search distance as the radius. And if the locating request does not carry the searching distance, the server uses the default searching distance.

Then, the server searches n other devices with the current geographic position in the target area, and sends a positioning instruction to the found n other devices, wherein the positioning instruction carries the first identifier of the target device. And other equipment carries out Bluetooth positioning on the target equipment according to the first identifier of the target equipment and sends respective Bluetooth positioning results to the server. Optionally, each bluetooth positioning result comprises: the geographic location of the target device at the time of discovery, or the target device is not discovered.

The server collects the received Bluetooth positioning results and determines the final positioning result to feed back to the terminal. And the terminal receives and displays the feedback result.

For example, the server receives only a bluetooth positioning result sent by another device, where the bluetooth positioning result carries a geographic location, and the server determines the geographic location as a final positioning result.

For another example, the server receives bluetooth positioning results sent by a plurality of other devices, and each bluetooth positioning result carries a plurality of geographic positions, and then the server determines the central positions of the plurality of geographic positions as final positioning results.

It should be noted that step 608 may also be triggered manually by the user.

The embodiment also enables the remote positioning instruction when the distance between the current geographic position of the terminal and the latest occurrence position of the target device is greater than a preset threshold. The server and other equipment auxiliary terminals complete the Bluetooth positioning of the target equipment, and the remote positioning function of the target equipment can be realized.
