Embodiments of the present application provide a method for reminding and positioning a missing device, a system for reminding and positioning a missing device, an electronic device, a computer-readable storage medium, and a computer program product, respectively, and these embodiments will be described in detail below.

Referring to fig. 1, fig. 1 is a schematic diagram illustrating an implementation environment of a method for reminding and positioning a legacy device according to an exemplary embodiment of the present application.

Referring to fig. 1, an implementation environment may include an in-vehicle terminal 110, a mobile device 120, and a user terminal 130. The in-vehicle terminal 110 includes at least one of a car system, a bluetooth probe, an in-vehicle smart assistant, a GPS (Global Positioning System ) positioning system, and the like. The mobile device 120 refers to a mobile device with bluetooth functionality, including but not limited to a smart phone, a notebook computer, a tablet computer, a smart watch, a smart bracelet, a bluetooth headset, etc. The user terminal 130 may be any terminal device supporting installation of an application program, such as a smart phone, a tablet computer, a notebook computer, or a wearable device. The vehicle-mounted terminal 110 is configured to obtain device list information by communicating with the mobile device 120, and determine whether the mobile device 120 is left in the vehicle according to the device list information; the vehicle-mounted terminal 110 is further configured to communicate with the user terminal 130, push a drop-out reminding message to the user terminal 130 to remind a user when there is a drop-out device, and locate the target device in response to a locating instruction sent by the user terminal 130, so as to generate relative position information of the target device and the vehicle and feed back the relative position information to the user terminal 130, so that the user can find the target device dropped in the vehicle.

The vehicle-mounted terminal 110 obtains device list information, where the device list information includes a first device list collected at a vehicle power-on locking time and a second device list collected at a vehicle power-off locking time, matches the first device list with the second device list, generates a drop reminding message based on the drop reminding message and pushes the drop reminding message to a user if the drop reminding message is obtained, determines a target device according to a target device identifier in the positioning instruction and positions the target device in response to the positioning instruction, and obtains target position information of the target device to generate relative position information of the target device and the vehicle and feeds the relative position information back to the user. Therefore, the technical scheme of the embodiment of the application can remind the user when the mobile device falls in the car, and locate the target device when the user inquires the target device, so that the user is prompted to prompt the specific position of the target device in the car, the searching time of the user for the target device is reduced, convenience is brought to the user, and the service level of the intelligent car is improved.

It should be noted that, the method for reminding and positioning the legacy device provided in the embodiments of the present application is generally specifically executed by the vehicle terminal 110, the mobile device 120, and the user terminal 130.

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for reminding and positioning a legacy device according to an exemplary embodiment of the present application. The method may be applied to the implementation environment shown in fig. 1 and specifically performed by the in-vehicle terminal 110, the mobile device 120, and the user terminal 130 in the implementation environment. It should be understood that the method may be applied to other exemplary implementation environments and be specifically executed by devices in other implementation environments, and the implementation environments to which the method is applied are not limited by the present embodiment.

Referring to fig. 2, in an exemplary embodiment, the method for reminding and positioning the missing device at least includes steps S210 to S230, which are described in detail as follows:

step S210, acquire device list information.

In one embodiment of the application, mobile devices around a vehicle and device information of the mobile devices are acquired at a vehicle power-on locking moment and a vehicle power-off locking moment respectively through a Bluetooth wireless probe, device list information is generated based on the device information of the mobile devices, and the device list information comprises a first device list acquired at the vehicle power-on locking moment and a second device list acquired at the vehicle power-off locking moment. Wherein the device information includes at least one of a device name, a device type, a device identification, a device physical address, and the like. The device physical address is the MAC address (Media Access Control Address ) of the mobile device, which is an address used to identify the location of the network device.

Since the searched device only represents the mobile devices around the vehicle, the searched device cannot be considered to be the mobile device in the vehicle, if bluetooth searching is performed only at the time of power-down locking of the vehicle, the searched device is used as the missing device of the user, the mobile devices in other vehicles are used as the missing devices of the user of the vehicle easily and mistakenly, and the accuracy of judging the missing device is not high. Therefore, the technical scheme of the embodiment respectively obtains the first equipment list collected at the vehicle power-on locking moment and the second equipment list collected at the vehicle power-off locking moment, and further matches the first equipment list and the second equipment list to judge whether the missing equipment exists in the vehicle or not, so that the accuracy of judging the missing equipment is effectively improved.

It should be appreciated that the bluetooth function of the mobile device in the vehicle should be guaranteed to be on prior to acquiring the mobile device around the vehicle.

In one specific embodiment of the application, a device drop reminding function switch is added in an intelligent assistant (vehicle-mounted intelligent assistant) at a vehicle side (vehicle system), and a state is opened by default, so that the state is synchronized to a eidolon (vehicle-mounted eidolon); the function prompt explanation and the skill display diagram are added in the fairy capability, and the mobile device with the Bluetooth function is enabled to be in a visible condition by prompting the owner to open the Bluetooth switch functions of mobile devices such as a mobile phone, a tablet personal computer, a notebook personal computer, a smart watch and the like in real time.

In one embodiment of the present application, step S210 includes the steps of:

step S211, monitoring the vehicle state, if it is monitored that the vehicle state is powered on and locked, performing a bluetooth search, and if the device is searched, generating a first device list based on the device type, the device identifier and the device physical address of each device obtained by the bluetooth search.

In one embodiment of the application, a vehicle state is monitored, the vehicle state comprises a vehicle ignition state and a vehicle door lock state, if the vehicle ignition state is monitored to be powered on and the vehicle door lock state is monitored to be locked, bluetooth searching is conducted through a bluetooth wireless probe, if at least one device is searched, a corresponding relation is configured for the device type, the device identification and the device physical address of each device, a device data set is generated, at least one device data set is obtained, and a first device list is created based on the obtained device data set. If no equipment is searched, the user can be reminded to start the Bluetooth function of the mobile equipment, for example, the user is prompted to start the Bluetooth switches of all the mobile equipment in the vehicle through the voice of the vehicle-mounted genie, and Bluetooth searching is periodically performed once until the equipment is searched. In addition, the number of times of carrying out the Bluetooth search once can be counted, and if the number of times exceeds the preset number of times, the Bluetooth search is not carried out once again.

Step S212, if the vehicle state is monitored to be powered down and locked, a secondary Bluetooth search is performed, and if equipment is searched, a second equipment list is generated based on the equipment type, the equipment identification and the equipment physical address of each equipment obtained by the secondary Bluetooth search.

In one embodiment of the present application, if it is monitored that the ignition state of the vehicle is powered down and the door lock state of the vehicle is locked, a secondary bluetooth search is performed through a bluetooth wireless probe, if at least one device is searched, a corresponding relationship is configured for a device type, a device identifier and a device physical address of each device, and a device data set is generated, so that at least one device data set is obtained, and a second device list is created based on the obtained device data set. If no equipment is searched, the fact that no missing equipment exists in the vehicle is indicated.

Step S220, the first equipment list and the second equipment list are matched, if a missing equipment list is obtained, a missing reminding message is generated based on the missing equipment list and is pushed to a user.

In one embodiment of the application, the device in the first device list and the device in the second device list are matched, and whether the missing device exists in the vehicle is determined according to a matching result. If the equipment which is successfully matched exists, the fact that the equipment which is lost exists in the vehicle is indicated, a list of the lost equipment is generated according to the equipment which is successfully matched, and a lost reminding message is generated based on the list of the lost equipment and is pushed to a user. The method is characterized in that a short message is adopted to push the drop reminding message to the user, a related application program notification mode is adopted to push the drop reminding message to the user, the drop reminding message can be 'you have mobile equipment to drop in a car', and further, the type of equipment can be prompted in the drop reminding message. If all the matching fails, the fact that no missing equipment exists in the vehicle is indicated.

In one embodiment of the present application, step S220 includes the steps of:

step S221, the device physical address of the first device list is matched with the device physical address of the second device list, and a missing device list is generated based on the device type and the device identifier corresponding to the successfully matched device physical address.

In one embodiment of the present application, the MAC addresses (device physical addresses) in the first device list are compared to the MAC addresses in the second device list. If one MAC address in the first equipment list is the same as one MAC address in the second equipment list, the MAC address is determined to be the successfully matched MAC address, and the missing equipment data set can be generated according to the equipment type and the equipment identifier corresponding to the successfully matched MAC address. In addition, the MAC address for which the match was successful may also be added to the legacy device data set. Thereby obtaining at least one legacy device data set, and creating a legacy device list based on the obtained legacy device data set.

It should be understood that each device in the network has a unique network identification, i.e., a MAC address, which is written inside the hardware when produced by the manufacturer of the network device, and is unique as if it were an identification card number on an identification card. Thus, the MAC address of each device is different as long as the MAC address of the device is not changed.

Step S222, the drop device list is sent to the vehicle-mounted eidolon, so that the vehicle-mounted eidolon generates a drop reminding message based on the device types in the drop device list and pushes the drop reminding message to a user.

In an embodiment of the present application, after receiving the list of the missing devices, the vehicle-mounted eidolon may send a preset missing alert message to the user terminal to prompt that the user has a mobile device missing in the vehicle, further, may extract all device types from the list of missing devices, generate the missing alert message according to the device types, and send the missing alert message to the user terminal to prompt the user which specific mobile device or mobile devices are missing in the vehicle. For example, when the extracted device type has a cell phone and a bluetooth headset, the drop alert message may be "you's cell phone and bluetooth headset are dropped in the car". In addition, before the device list is sent to the vehicle-mounted eidolon, the device types in the device list can be identified, if the device types are mobile phones, so that the user is reminded in a mode that the vehicle lamp flashes or the vehicle whistles while the device types push the device-to-fall reminding message, and the situation that the user cannot receive the device-to-fall reminding in time when the user terminal is the mobile phone can be avoided.

In one embodiment of the present application, after obtaining the list of the missing devices, the method for reminding and positioning the missing devices further includes:

step S22201 locates the vehicle to obtain vehicle position information, locates the smart car key of the vehicle to obtain key position information of the smart car key, and calculates a first distance between the vehicle and the smart car key according to the vehicle position information and the key position information.

In one embodiment of the present application, after the vehicle is powered down after locking, if the user is close to the vehicle, the bluetooth wireless probe can also search for the mobile device that the user has taken away, and may misunderstand that the mobile device is also left in the vehicle, so, in order to avoid this situation, the distance between the user and the vehicle may be determined, and when the distance between the user and the vehicle exceeds a certain distance, the missing reminding message is pushed again. In general, a smart car key of a vehicle is carried by a user, and a distance between the smart car key and the vehicle can be used as a distance between the user and the vehicle. Illustratively, the vehicle is positioned in real time or periodically through a GPS to obtain the vehicle position information. Meanwhile, the positioning information of the intelligent vehicle key of the vehicle, namely the key position information, is acquired in real time or periodically through the keyless entry system. It should be appreciated that vehicles are typically designed with a keyless entry system that has the function of locating the position of a key of the smart car. And calculating a first distance between the vehicle and the intelligent vehicle key according to the vehicle position information and the key position information, comparing the first distance with a preset distance threshold value, and determining whether to push the missing reminding message according to a comparison result. It should be noted that, when periodic positioning is used, the interval time should not be too long, and may be 1 second, or other time set by those skilled in the art.

Step S22202, if the first distance is greater than or equal to the preset distance threshold, sending the drop device list to the vehicle-mounted eidolon, so that the vehicle-mounted eidolon generates a drop reminding message based on the device types in the drop device list and pushes the drop reminding message to the user.

In one embodiment of the present application, if the first distance is smaller than the preset distance threshold, which indicates that the user is very close to the vehicle at this time, the monitoring of the implementation distance between the vehicle and the smart car key is continued until the first distance is equal to the preset distance threshold. If the first distance is greater than or equal to a preset distance threshold, the user is considered to leave the vehicle at the moment and has a certain distance from the vehicle, and the drop-off device list is sent to the vehicle-mounted eidolon, so that the vehicle-mounted eidolon generates drop-off reminding information based on the device types in the drop-off device list and pushes the drop-off reminding information to the user, and the user is prompted that the mobile device is dropped in the vehicle. The specific procedure for pushing the drop reminding message is described in the embodiment of step S222, and will not be described in detail here. Illustratively, the preset distance threshold may be 3 meters, or other threshold set by one of skill in the art.

Step S230, in response to a positioning instruction of the user, determining the target equipment according to the target equipment identifier and positioning the target equipment to obtain target position information of the target equipment, so as to generate relative position information of the target equipment and the vehicle and feed back the relative position information to the user.

In one embodiment of the application, after receiving the drop reminding message, the user can query the drop condition of the target device through the user terminal to determine whether the target device is truly dropped in the vehicle and a specific position in the vehicle. After the user clicks the target device in the related application program of the user terminal, the user terminal may directly or indirectly send a positioning instruction to the vehicle-mounted terminal, where the positioning instruction includes a target device identifier of the target device. The vehicle-mounted terminal responds to a positioning instruction of a user, determines target equipment according to the target equipment identification, detects and positions the target equipment through a Bluetooth wireless probe to obtain target position information of the target equipment, so as to generate relative position information of the target equipment and a vehicle and feed back the relative position information to the user, for example, whether the target equipment is in a vehicle or out of the vehicle relative to the vehicle, if the target equipment is out of the vehicle, the target equipment is not left in the vehicle, and if the target equipment is in the vehicle, the specific position in the vehicle such as a front seat, a rear seat or a trunk is further determined.

In one embodiment of the present application, step S230 includes the steps of:

matching the device physical address of the target device from the list of the lost devices according to the target device identifier, and carrying out three Bluetooth searches;

If at least one device to be matched is searched, and the device physical address of the device to be matched is the same as the device physical address of the target device, determining the device to be matched as the target device, and positioning the target device to obtain the target position information.

In this embodiment, when the second device list is collected, if the user is close to the vehicle, the mobile device carried away by the user may be searched by the bluetooth wireless probe, and based on this situation, the mobile device carried away by the user may be determined to be left in the vehicle, so the obtained list of left devices is not necessarily completely accurate. It is therefore necessary to determine again whether the target device is truly left in the vehicle before locating the target device.

Illustratively, the target device identifier is extracted from the positioning instruction, and the MAC address corresponding to the target device identifier, that is, the MAC address of the target device, may be matched from any one of the first device list, the second device list, and the missing device list according to the target device identifier. And meanwhile, carrying out three Bluetooth searches on equipment around the vehicle through a Bluetooth wireless probe, if at least one piece of equipment and equipment information of the equipment are searched, taking the equipment as equipment to be matched, and taking the MAC address of the equipment as the MAC address of the equipment to be matched. And comparing the MAC addresses of all the devices to be matched with the MAC address of the target device, and when the MAC address of any one device to be matched is the same as the MAC address of the target device, determining that the target device is left in the vehicle again, wherein the device to be matched is the target device, and further positioning the target device to obtain the target position information of the target device. If all the MAC addresses of the devices to be matched are different from the MAC address of the target device, or no device is searched, the fact that the target device is not left in the vehicle is indicated, and the word or voice feedback of 'the device is not left in the vehicle' can be carried out through the vehicle-mounted genie to the user. The technical scheme of the embodiment can confirm whether the target equipment is left in the vehicle again, and further improves the accuracy of judging the left equipment.

In one embodiment of the present application, positioning a target device to obtain target location information of the target device includes the following steps:
