Description
Technical Field
[0001] The present invention relates to the technical field of object anti-lost technology, and in particular to a lost object retrieval system and method. Background Art
[0002] There are two general implementation solutions for anti-lost products on the market. The first is to build a positioning device into the anti-lost device. This method can solve the problem of long-distance item tracking, but it is expensive, so it has not been promoted. The other is to connect to the mobile phone via Bluetooth, and then send instructions to Bluetooth through the mobile phone to make the anti-lost device ring. This method is inexpensive, but is limited by the Bluetooth connection distance (effective distance is about 10 meters) and cannot achieve long-distance item location tracking, and basically cannot meet the needs of long-distance item search.
[0003] However, in daily life, when users find that an item is lost, they are often already a long distance away from the lost item. At this time, the conventional solution of connecting to a mobile phone via Bluetooth to retrieve the lost item is no longer applicable.
[0004] Therefore, how to reduce costs while meeting the needs of searching for items over long distances has become a technical problem that needs to be solved urgently. Summary of the invention
[0005] In view of this, it is necessary to provide a lost object retrieval system and method to solve the current problem of high cost when searching for lost objects over long distances.
[0006] In order to solve the above problems, the present invention provides a lost object recovery system, comprising: A communication module disposed on the target object, used to establish a connection with the target terminal; A target terminal, used to record a target position and determine a retrieval path for the target object based on the target position and a current position; The target position is the position of the communication module when the target terminal is disconnected from the communication module.
[0007] In a possible implementation, the communication module is further configured to bind with account information corresponding to the target terminal after establishing a connection with the target terminal.
[0008] In a possible implementation, the target terminal is further used to determine a target area based on the target position, where the target area is a circular area with the target position as the center and the connection range of the communication module as the radius; The retrieval path of the target object is the shortest path from the current position to the boundary of the target area.
[0009] In a possible implementation, when the communication module is not connected to the target terminal, it sends a Bluetooth connection signal at a first frequency within a preset time period, and after the preset time period, it sends a Bluetooth connection signal at a second frequency, and the first frequency is greater than the second frequency.
[0010] In a possible implementation, the target terminal is further configured to, after reaching a boundary of the target area, search for the communication module based on Bluetooth communication and binding information with the communication module, and re-establish connection with the communication module.
[0011] In a possible implementation, the communication module is further provided with a prompt module and a power recording module; The target terminal is further configured to obtain the remaining power of the communication module from the power recording module after re-establishing the connection with the communication module; The target terminal is also used to control the prompt module to emit a prompt sound when the remaining power of the communication module is greater than a preset threshold; When the remaining power of the communication module is less than or equal to a preset threshold, and when the strength of the Bluetooth connection signal sent by the communication module is greater than the preset strength threshold, the prompt module is controlled to emit a prompt sound.
[0012] The present invention also provides a lost object recovery method, which is applied to a target terminal in the lost object recovery system as described above, comprising: Establishing a connection with a communication module disposed on the target object, and binding with the communication module based on the account information; When disconnecting from the communication module, recording the location of the communication module as the target location; A retrieval path for the target object is determined based on the target position and the current position.
[0013] In a possible implementation manner, determining a path for finding the target object based on the target position and the current position includes: Determine a target area based on the target position, the target area being a circular area with the target position as the center and the connection range of the communication module as the radius; The shortest path from the current position to the boundary of the target area is determined as a path for finding the target object.
[0014] In a possible implementation, the method further includes: After reaching the boundary of the target area, based on the Bluetooth communication and the binding information with the communication module, the communication module is searched and the connection with the communication module is re-established.
[0015] In a possible implementation, the method further includes: After re-establishing the connection with the communication module, obtaining the remaining power of the communication module; When the remaining power of the communication module is greater than a preset threshold, controlling the prompt module to emit a prompt sound; When the remaining power of the communication module is less than or equal to a preset threshold, and when the strength of the Bluetooth connection signal sent by the communication module is greater than the preset strength threshold, the prompt module is controlled to emit a prompt sound.
[0016] The beneficial effects of the present invention are as follows: the lost object recovery system and method provided by the present invention mainly rely on the positioning function of the target terminal to achieve the recovery of the lost object when recovering the lost object. Only the connection function needs to be realized on the anti-lost device (i.e., the communication module) side, and there is no need to additionally set up a positioning module on the anti-lost device side, thereby reducing the cost of long-distance recovery of the lost object. The present invention reduces the cost of long-distance recovery of the lost object while achieving long-distance recovery of the lost object. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0018] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0020] In the description of the present invention, reference to an "embodiment" means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive of other embodiments. It is explicitly and implicitly understood by those skilled in the art that the described embodiments may be combined with other embodiments.
[0021] There are two general implementation solutions for anti-lost products on the market. The first is to build a positioning device into the anti-lost device. This method can solve the problem of long-distance item tracking, but it is expensive, so it has not been promoted. The other is to connect to the mobile phone via Bluetooth, and then send instructions to Bluetooth through the mobile phone to make the anti-lost device ring. This method is inexpensive, but is limited by the Bluetooth connection distance (effective distance is about 10 meters) and cannot achieve long-distance item location tracking, and basically cannot meet the needs of long-distance item search.
[0022] However, in daily life, when users find that an item is lost, they are often already a long distance away from the lost item. At this time, the conventional solution of connecting to a mobile phone via Bluetooth to retrieve the lost item is no longer applicable.
[0023] In order to achieve long-distance recovery of lost objects at a lower cost, the present invention provides a lost object recovery system.
[0024] The specific embodiments are described in detail below: A specific embodiment of the present invention discloses a lost object retrieval system, combined with Figure 1 Come and see, Figure 1 This is a schematic diagram of the structure of an embodiment of a lost object retrieval system provided by the present invention. The lost object retrieval system 100 includes: The communication module 102 provided on the target object 101 is used to establish a connection with the target terminal 103; A target terminal 103, used for recording a target position and determining a retrieval path of the target object 101 based on the target position and the current position; The target location is the location of the communication module 102 when the target terminal 103 is disconnected from the communication module 102 .
[0025] During implementation, the communication module and the target object may be physically connected first, for example, the communication module may be adhered to the target object, or the communication module and the target object may be physically connected using a connecting component such as a lock, which is not specifically limited in the present invention.
[0026] Afterwards, the target terminal (such as a smart device such as a mobile phone or a smart watch) can be connected to the communication module. While the target terminal remains connected to the communication module, it can maintain the location of the communication module, providing a basis for subsequent retrieval when the target object is lost.
[0027] Generally, the target object and the target terminal are carried by the user, so the target terminal and the communication module are always connected. When the target object is lost, the target terminal will be disconnected from the communication module after leaving the connection range. When the target terminal is disconnected from the communication module, the target terminal can record the location of the communication module when the connection is disconnected as the target location, so as to provide path guidance when it is retrieved later.
[0028] When the user finds that the target object is lost, the user can determine the target object's retrieval path through the target location and current location recorded by the target terminal, and then find the target object according to the target object's retrieval path.
[0029] Compared with the prior art, the lost object recovery system provided in this embodiment mainly relies on the positioning function of the target terminal to achieve the recovery of the lost object. Only the connection function needs to be realized on the anti-lost device (i.e., the communication module) side, and there is no need to additionally set up a positioning module on the anti-lost device side, thereby reducing the cost of long-distance recovery of lost objects. The present invention reduces the cost of long-distance recovery of lost objects while achieving long-distance recovery of lost objects.
[0030] Exemplarily, the communication module is further configured to bind with the account information corresponding to the target terminal after establishing a connection with the target terminal.
[0031] Specifically, after the communication module establishes a connection with the target terminal, it can also bind to the account information corresponding to the target terminal. Binding to the account information corresponding to the target terminal instead of the target terminal itself is because there may be a situation where the communication module and the target terminal are lost at the same time. At this time, the user can log in through another terminal using the bound account information to achieve the recovery of the target object, thereby improving the flexibility of recovering the lost object.
[0032] Exemplarily, the target terminal is further used to determine a target area based on the target position, where the target area is a circular area with the target position as the center and the connection range of the communication module as the radius; The retrieval path of the target object is the shortest path from the current position to the boundary of the target area.
[0033] Specifically, since the communication module has a certain connection range, when retrieving the target object, it is not necessary to return to the target position, but only to return to the connection range of the communication model to achieve the target object. Therefore, the target terminal can also determine the circular area with the target position as the center and the connection range of the communication module as the radius as the target area, and then determine the shortest path from the current position to the boundary of the target area as the target object retrieval path, thereby improving the efficiency of lost object retrieval.
[0034] Exemplarily, when the communication module is not connected to the target terminal, it sends a Bluetooth connection signal at a first frequency within a preset time period, and sends a Bluetooth connection signal at a second frequency after the preset time period, and the first frequency is greater than the second frequency.
[0035] Specifically, in order to save the power of the communication module, when the communication module fails to establish a connection with the target terminal, the communication module can send a Bluetooth connection signal at a first frequency within a preset time, and after the preset time, send a Bluetooth connection signal at a second frequency, and the first frequency is greater than the second frequency. That is, if the communication module fails to establish a connection with the target terminal within the preset time, the communication module can reduce the frequency of sending the Bluetooth connection signal to achieve power saving of the module.
[0036] Exemplarily, the target terminal is further configured to, after reaching a boundary of the target area, search for the communication module based on Bluetooth communication and binding information with the communication module, and re-establish connection with the communication module.
[0037] Specifically, after the user reaches the boundary of the target area according to the search path of the target object, the user can use the target terminal to search for the communication module through Bluetooth communication and binding information between the target terminal and the communication module, and re-establish connection with the communication module after the search is completed.
[0038] Exemplarily, the communication module is further provided with a prompt module and a power recording module; The target terminal is further configured to obtain the remaining power of the communication module from the power recording module after re-establishing the connection with the communication module; The target terminal is also used to control the prompt module to emit a prompt sound when the remaining power of the communication module is greater than a preset threshold; When the remaining power of the communication module is less than or equal to a preset threshold, and when the strength of the Bluetooth connection signal sent by the communication module is greater than the preset strength threshold, the prompt module is controlled to emit a prompt sound.
[0039] Specifically, in order to further improve the efficiency of recovering lost objects, a prompt module can also be set in the communication module, and in order to further save the power of the communication module, a power recording module can also be set in the communication module. After the target terminal re-establishes a connection with the communication module, it can first obtain the remaining power of the communication module from the power recording module. When the remaining power of the communication module is greater than the preset threshold, it means that the remaining power of the communication module is sufficient, and the target terminal can directly control the prompt module (such as a buzzer) to emit a prompt sound. When the remaining power of the communication module is less than or equal to the preset threshold, it means that the remaining power of the communication module is insufficient. At this time, the target terminal can judge the distance from the communication module according to the strength of the Bluetooth connection signal sent by the communication module. When the strength of the Bluetooth connection signal sent by the communication module is greater than the preset strength threshold, it means that the distance to the communication module is close enough. At this time, the prompt module is controlled to emit a prompt sound, and when the strength of the Bluetooth connection signal sent by the communication module is less than or equal to the preset strength threshold, the prompt module is not controlled.
[0040] The present invention also discloses a lost object recovery method, which is applied to the target terminal in the lost object recovery system as described above, and is combined with Figure 2 Come and see, Figure 2 The flowchart of an embodiment of the lost object recovery method provided by the present invention includes steps S201 to S203, wherein: In step S201, a connection is established with a communication module disposed on a target object, and binding is performed with the communication module based on account information; In step S202, when disconnecting from the communication module, the location of the communication module is recorded as the target location; In step S203 , a retrieval path for the target object is determined based on the target position and the current position.
[0041] During implementation, the target terminal can first establish a connection with the communication module on the target object and bind it to the communication module through account information. When the communication module and the target terminal are lost at the same time, the user can log in through another terminal using the bound account information to retrieve the target object.
[0042] When disconnected from the communication module, the target terminal may record the location of the communication module at this time as the target location, and then determine a retrieval path for the target object according to the target location and the current location.
[0043] Compared with the prior art, the lost object recovery method provided in this embodiment mainly relies on the positioning function of the target terminal to achieve the recovery of the lost object. Only the connection function needs to be realized on the anti-lost device (i.e., the communication module) side, and there is no need to additionally set up a positioning module on the anti-lost device side, thereby reducing the cost of long-distance recovery of lost objects. The present invention reduces the cost of long-distance recovery of lost objects while achieving long-distance recovery of lost objects.
[0044] Exemplarily, determining a path for finding the target object based on the target position and the current position includes: Determine a target area based on the target position, the target area being a circular area with the target position as the center and the connection range of the communication module as the radius; The shortest path from the current position to the boundary of the target area is determined as a path for finding the target object.
[0045] Specifically, since the communication module has a certain connection range, when retrieving the target object, it is not necessary to return to the target position, but only to return to the connection range of the communication model to achieve the target object. Therefore, the target terminal can also determine the circular area with the target position as the center and the connection range of the communication module as the radius as the target area, and then determine the shortest path from the current position to the boundary of the target area as the target object retrieval path, thereby improving the efficiency of lost object retrieval.
[0046] Exemplarily, the method further includes: After reaching the boundary of the target area, based on the Bluetooth communication and the binding information with the communication module, the communication module is searched and the connection with the communication module is re-established.
[0047] Specifically, after the user reaches the boundary of the target area according to the search path of the target object, the user can use the target terminal to search for the communication module through Bluetooth communication and binding information between the target terminal and the communication module, and re-establish connection with the communication module after the search is completed.
[0048] Exemplarily, the method further includes: After re-establishing the connection with the communication module, obtaining the remaining power of the communication module; When the remaining power of the communication module is greater than a preset threshold, controlling the prompt module to emit a prompt sound; When the remaining power of the communication module is less than or equal to a preset threshold, and when the strength of the Bluetooth connection signal sent by the communication module is greater than the preset strength threshold, the prompt module is controlled to emit a prompt sound.
[0049] Specifically, in order to further improve the efficiency of recovering lost objects, after the target terminal re-establishes a connection with the communication module, it can first obtain the remaining power of the communication module. When the remaining power of the communication module is greater than the preset threshold, it indicates that the remaining power of the communication module is sufficient, and the target terminal can directly control the prompt module (such as a buzzer) to emit a prompt sound. When the remaining power of the communication module is less than or equal to the preset threshold, it indicates that the remaining power of the communication module is insufficient. At this time, the target terminal can judge the distance from the communication module based on the strength of the Bluetooth connection signal sent by the communication module. When the strength of the Bluetooth connection signal sent by the communication module is greater than the preset strength threshold, it indicates that the distance to the communication module is close enough. At this time, the prompt module is controlled to emit a prompt sound. When the strength of the Bluetooth connection signal sent by the communication module is less than or equal to the preset strength threshold, the prompt module is not controlled.
[0050] The following is a specific application scenario to better illustrate the technical solution of the present invention: Combination Figure 3 Come and see, Figure 3 This is a flow chart of an embodiment of a binding process between a target terminal and a communication module provided by the present invention, taking a mobile phone as the target terminal as an example: Use your mobile phone to search for Bluetooth. After searching for the anti-lost device (i.e., the communication module), establish a Bluetooth connection with the anti-lost device and bind it with the anti-lost device through the currently logged-in account information.
[0051] After the anti-loss device is bound to an account, only the account can actively unbind it from the anti-loss device, and other users cannot unbind the device. In addition, users can also use the account information to log in to other devices and match them with the anti-loss device.
[0052] The mobile phone can complete the binding with the anti-loss device in offline state (i.e. not connected to the Internet). After connecting to the Internet, the mobile phone can upload the binding information with the anti-loss device to the server, so that it can subsequently log in the account information through other terminals and match and connect with the anti-loss device.
[0053] The following is an introduction through two specific embodiments of target object retrieval: Combination Figure 4 Come and see, Figure 4 This is a schematic diagram of an embodiment of a target object retrieval path provided by the present invention. The anti-lost device is lost at point A, and the target terminal is disconnected from the anti-lost device at point B. At this time, the target terminal records the position of the anti-lost device at point A when the anti-lost device is disconnected.
[0054] At point C, the user finds that the target object is lost. At this time, the target terminal connects the current position point C with the target position point A. There are no obstacles on the connecting line, so it can directly follow the connecting line between the current position point C and the target position point A to point D and reach the boundary of the target area. Then the target terminal controls the buzzer on the anti-lost device to sound a prompt, and the user finds the target object.
[0055] Combination Figure 5 Come and see, Figure 5 This is a schematic diagram of another embodiment of the target object retrieval path provided by the present invention. The anti-lost device is lost at point A, and the target terminal is disconnected from the anti-lost device at point B. At this time, the target terminal records the position of the anti-lost device at point A when the anti-lost device is disconnected.
[0056] At point C, the user finds that the target object is lost. At this time, the target terminal connects the current position point C with the target position point A. There is an obstacle on the connecting line. At this time, you can first go along a straight line to point E on the side of the obstacle, and then go along the connecting line between point E and point C to point D to reach the boundary of the target area. Then the target terminal controls the buzzer on the anti-lost device to sound a prompt, and the user finds the target object.
[0057] Of course, in the actual retrieval process, there may be a more complex retrieval path. In this case, the retrieval path can be planned with the help of the navigation function of the target terminal, that is, the shortest path from the current position to the boundary of the target area can be achieved through the navigation function of the target terminal. The present invention does not specifically limit the specific path planning process.
[0058] The present invention discloses a lost object recovery system and method. When recovering a lost object, the recovery of the lost object is mainly achieved by relying on the positioning function of a target terminal. Only a connection function needs to be realized on the anti-lost device (i.e., a communication module) side, and there is no need to additionally set a positioning module on the anti-lost device side, thereby reducing the cost of long-distance recovery of the lost object. The present invention reduces the cost of long-distance recovery of the lost object while realizing long-distance recovery of the lost object.
[0059] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
