[0025] As described in the background technology, there is an urgent need for an object anti-lost method that can effectively solve the object anti-lost problem.

[0026] The inventor of the present invention has found through research that accurately determining the location of an item is a key factor in preventing the item from being lost. In the prior art, the location of an item is usually determined by a single positioning technology such as GPS positioning technology, Bluetooth positioning technology or ultra-wideband positioning technology. When a single positioning technology is used to determine the location of an item, it is not possible to simultaneously achieve the effects of improving positioning accuracy, reducing power consumption and reducing costs. For example, ultra-wideband positioning technology has high positioning accuracy, but weak penetration ability. It is generally necessary to increase the positioning distance by increasing power, which consumes a lot of power, or to increase the effective distance by adding base stations, but this method is costly and less practical.

[0027] In order to solve the above technical problems, an embodiment of the present invention provides an anti-lost method for an object. In the scheme of the embodiment of the present invention, if the distance between the object and the mobile terminal at the current moment is less than or equal to the first preset threshold, the position of the object at the next moment is obtained from the first positioning unit, and if the distance between the object and the mobile terminal at the current moment is greater than the first preset threshold, the position of the object at the next moment is obtained from the second positioning unit. Since the first positioning unit uses ultra-wideband positioning technology to determine the position of the object, and the second positioning unit uses Bluetooth technology to determine the position of the object, the scheme of the embodiment of the present invention determines the way to obtain the position of the object according to the distance between the object and the mobile terminal, and can combine ultra-wideband positioning technology with Bluetooth positioning technology. When the distance between the object and the mobile terminal is far, Bluetooth positioning technology can be used to reduce power consumption and save costs. When the distance between the object and the mobile terminal is close, ultra-wideband positioning technology is used to improve positioning accuracy so as to accurately determine the position of the object.

[0028] In order to make the above-mentioned objects, features and beneficial effects of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] Reference Figure 1 , Figure 1 1 is a flowchart of an anti-lost method for an item in an embodiment of the present invention. The method can be executed by a terminal, and the terminal can be any existing terminal with data receiving and processing capabilities. In a specific example, the method can be executed by a controller, and the controller can be set on an item. The item can be any existing item with anti-lost requirements. In a specific example, the item can be a suitcase, but it is not limited to this. Figure 1 The method shown can accurately determine the location of an object, thereby preventing the object from being lost. Figure 1 The anti-loss method shown may include the following steps:

[0030] Step S101: obtaining the current position of the object and the position of the mobile terminal, and calculating the distance between the object and the mobile terminal;

[0031] Step S102: Compare the distance with a first preset threshold value. If the distance is less than or equal to the first preset threshold value, obtain the position of the object at the next moment from the first positioning unit; otherwise, obtain the position of the object at the next moment from the second positioning unit.

[0032] It is understandable that, in a specific implementation, the method can be implemented in the form of a software program, which runs in a processor integrated inside a chip or a chip module; or, the method can be implemented in the form of hardware or a combination of hardware and software.

[0033] In the specific implementation of step S101, the mobile terminal may be a terminal device used by the user, and the mobile terminal may be any existing appropriate terminal, for example, a mobile phone, a tablet computer, an electronic bracelet, etc., but is not limited thereto. Specifically, the mobile terminal and the item are bound, in other words, the mobile terminal and the bound item correspond to the same user.

[0034] Furthermore, the location of the object at the current moment can be obtained from a positioning module of the object. Specifically, the object can include a positioning module, and the positioning module can be used to determine the location of the object.

[0035] Furthermore, the current position of the mobile terminal can also be obtained. Specifically, the position of the mobile terminal can be obtained directly from the mobile terminal, or from a cloud server. The embodiment of the present invention does not limit the method for obtaining the position of the mobile terminal.

[0036] In a specific example, when the distance between the object and the mobile terminal is less than or equal to the third preset threshold, the location of the mobile terminal can be directly obtained from the mobile terminal, and the location of the object can also be sent to the mobile terminal; when the distance between the object and the mobile terminal is greater than the third preset threshold, the location of the mobile terminal can be obtained from the cloud server, and the location of the object can be sent to the cloud server, so that the cloud server forwards the location of the object to the mobile terminal. Among them, the third preset threshold can be pre-set. Adopting such a scheme can accurately determine the location of the mobile terminal, and the user can also obtain the accurate location of the object through the mobile terminal, which is conducive to avoiding the problem of data loss caused by direct data transmission when the distance between the mobile terminal and the object is far.

[0037] Furthermore, the distance between the object and the mobile terminal at the current moment may be calculated and determined according to the location of the object and the location of the mobile terminal at the current moment.

[0038] In the specific implementation of step S102, the location of the object at the next moment may be obtained according to the relationship between the distance between the object and the mobile terminal at the current moment and one or more preset thresholds.

[0039] In a specific embodiment, the positioning module of the object may include a first positioning unit and a second positioning unit, wherein the first positioning unit uses ultra-wideband positioning (UWB) technology to determine the position of the object, and the second positioning unit uses Bluetooth positioning technology to determine the position of the object. More specifically, the second positioning unit may use Bluetooth low energy 5.0 positioning technology to obtain the position of the object, or may use other Bluetooth positioning technologies to obtain the position of the object, and the embodiment of the present invention is not limited to this.

[0040] Furthermore, the distance between the object and the mobile terminal at the current moment can be compared with the first preset threshold. If the distance is less than or equal to the first preset threshold, the position of the object at the next moment can be obtained from the first positioning unit. If the distance is greater than the first preset threshold, the position of the object at the next moment can be obtained from the second positioning unit. The first preset threshold can be pre-set, and the embodiment of the present invention does not limit the size of the first preset threshold.

[0041] In other words, when the distance between the object and the mobile terminal is large, the Bluetooth positioning technology can be used to determine the location of the object. When the distance between the object and the mobile terminal is small, the ultra-wideband positioning technology can be used to determine the location of the object.

[0042] In another specific embodiment, the positioning module of the object may further include a third positioning unit, which may use satellite positioning technology to obtain the location of the object. The embodiment of the present invention does not limit the specific method of satellite positioning technology. For example, the Global Positioning System (GPS) may be used to obtain the location of the object, or the BeiDou Navigation Satellite System (BDS) may be used to obtain the location of the object, but it is not limited to this.

[0043] Furthermore, the distance between the item and the mobile terminal at the current moment can be compared with the first preset threshold and the second preset threshold respectively. If the distance is greater than the second preset threshold, the location of the item at the next moment can be obtained from the third positioning unit; if the distance is less than or equal to the first preset threshold, the location of the item at the next moment can be obtained from the first positioning unit; if the distance is greater than the first preset threshold and less than or equal to the second preset threshold, the location of the item at the next moment can be obtained from the second positioning unit. It should be noted that the second preset threshold is greater than the first preset threshold. It should also be noted that the embodiment of the present invention does not limit the size relationship between the third preset threshold and the first preset threshold and the second preset threshold. With such a solution, the location of the item can be accurately determined when the item is outdoors, which is helpful to prevent the loss of the item.

[0044] Furthermore, the movement of the object to the mobile terminal can be controlled according to the position of the object and the position of the mobile terminal. In a specific example, the speed at which the object moves to the mobile terminal can be controlled according to the distance between the object and the mobile terminal. The greater the distance between the object and the mobile terminal, the greater the speed of movement.

[0045] Furthermore, when the distance between the object and the mobile terminal is greater than a preset safety distance threshold, an alarm reminder may be issued, and the embodiment of the present invention does not limit the specific manner of the alarm reminder. In a specific example, the object also includes an alarm, and a voice alarm may be issued through the alarm so that the user can quickly determine the location of the object. An alarm reminder message may also be sent to the mobile terminal to remind the user to check the location of the object at the current moment. The preset safety distance threshold may be pre-set, and the preset safety distance threshold may be less than or equal to the first preset threshold.

[0046] refer to Figure 2 , Figure 2 1 is a partial flow chart of the second method for preventing items from being lost in the embodiment of the present invention. Figure 2 The second method for preventing items from being lost is shown in Figure 1 The differences in the anti-loss methods shown are described below. Figure 2 The anti-loss method shown may include the following steps:

[0047] Step S201: obtaining an unlocking request;

[0048] Step S202: In response to the unlocking request, a first verification code request is sent to the cloud server, and a verification code is sent to the mobile terminal, so that the mobile terminal sends a second verification code request to the cloud server;

[0049] Step S203: Obtain a first verification code from the cloud server and a second verification code from the mobile terminal, and determine whether the first verification code and the second verification code are consistent. If yes, unlock the door.

[0050] In the specific implementation of step S201, an unlocking request can be obtained from the outside, and the unlocking request can be obtained from the mobile terminal or directly from the user. For example, the unlocking request can be a voice message, and the voice message can be a voice directly obtained from the user, but it is not limited to this.

[0051] In the specific implementation of step S202, after the unlocking request is obtained, a first verification code request can be sent to the cloud server. After receiving the first verification code request, the cloud server can send the first verification code to the object.

[0052] In addition, after obtaining the unlocking request, a verification code can be generated and sent to the mobile terminal. Further, after receiving the verification code, the mobile terminal can send a second verification code request to the cloud server. In other words, the verification code is used to trigger the mobile terminal to send a second verification code request to the cloud server. Further, when the cloud server receives the second verification code request, it can send the second verification code to the mobile terminal. After receiving the second verification code, the mobile terminal can forward the second verification code to the object.

[0053] In the specific implementation of step S203, the first verification code can be obtained from the cloud server, the second verification code can be obtained from the mobile terminal, and it can be determined whether the first verification code and the second verification code are consistent. If so, the lock can be unlocked. If the first verification code and the second verification code are inconsistent, and the number of inconsistencies within the preset time reaches a preset number threshold, an alarm reminder is issued. The preset time is a preset duration information, and the preset time and the preset number threshold can be pre-set. In a specific example, a voice alarm can be performed, wherein the volume of the voice alarm can be determined according to the distance between the object and the mobile terminal at the current moment.

[0054] In a specific example, before issuing an alarm reminder, it can be determined whether the distance between the object and the mobile terminal is less than or equal to a first preset threshold. If so, a voice alarm can be issued only through the alarm. Otherwise, a voice alarm is issued through the alarm and an alarm reminder message is sent to the mobile terminal to remind the user to check the location of the object in time.

[0055] about Figure 2 For more information about the second method for preventing items from being lost, see the above description of Figure 1 The relevant description will not be repeated here.

[0056] Reference Figure 3 , Figure 3 This is a partial flow chart of the third method for preventing the loss of articles in an embodiment of the present invention. The unlocking request is a voice message. Figure 3 The anti-loss method shown may include the following steps:

[0057] Step S301: determining whether the distance is less than the first preset threshold, and if so, performing voiceprint recognition on the voice information to obtain real voiceprint information;

[0058] Step S302: Compare the real voiceprint information with the preset voiceprint information. If the comparison is successful, determine whether the current posture of the object is the preset posture. If yes, unlock the door.

[0059] In the specific implementation of step S301, after obtaining the unlocking request, it can be determined whether the distance between the object and the mobile terminal at the current moment is less than the first preset threshold. If so, voiceprint recognition can be performed on the voice information to obtain real voiceprint information. The specific method of voiceprint recognition can be various existing voiceprint recognition methods, and the embodiment of the present invention is not limited to this.

[0060] In a specific example, if the distance between the object and the mobile terminal at the current moment is greater than the first preset threshold, the execution may continue. Figure 2 In another specific example, if the distance between the object and the mobile terminal at the current moment is greater than the first preset threshold, if an unlocking request is obtained, the unlocking request may be discarded, that is, no response is given to it.

[0061] In the specific implementation of step S302, the preset voiceprint information may be read, and the real voiceprint information may be compared with the preset voiceprint information, wherein the preset voiceprint information may be the voiceprint information of the user obtained in advance.

[0062] Furthermore, if the real voiceprint information is consistent with the preset voiceprint information, it can be further determined whether the posture of the object at the current moment is the preset posture. The preset posture can be pre-set according to the shape of the object. In a specific example, the object is a suitcase, and the suitcase includes multiple surfaces, wherein the preset posture is that a preset surface among the multiple surfaces is in contact with the ground, wherein the preset surface is pre-determined from the multiple surfaces of the suitcase.

[0063] Furthermore, if the current posture is the preset posture, the lock can be unlocked. If the current posture is not the preset posture, the posture of the object can be adjusted to make the object in the preset posture, and then unlocked. With such a solution, the lock can be automatically unlocked when the distance between the object and the mobile terminal is close, which simplifies the unlocking process while ensuring safety, and is conducive to improving the user experience.

[0067] The comparison module 42 is used to compare the distance with a first preset threshold value. If the distance is less than or equal to the first preset threshold value, the position of the object at the next moment is obtained from the first positioning unit; otherwise, the position of the object at the next moment is obtained from the second positioning unit.
