Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for determining whether a target returns to a designated location according to a first embodiment of the present invention.
The method for determining whether the target returns to the designated location described in this embodiment may be applied to electronic devices, such as an intelligent access device, an intelligent doorbell, and an intelligent monitoring device, which are installed at the designated location to determine whether the target returns to the designated location. The target may be a person or a pet, and the designated location may be a specific scene such as a home, an office, and the like, which is not limited herein.
It is to be understood that the method for determining whether the target returns to the specified location set forth in the present embodiment is not limited to the following steps.
S101: judging whether a first device at a specified place receives a trigger instruction;
in the present embodiment, the first device is installed at a specified place. When the suspected target object appears in the designated place, the first device receives the trigger instruction, that is, the first device senses that the suspected target object appears in the designated place, and further needs to judge whether the suspected target object is the target, so as to judge whether the target returns to the designated place.
S102: if yes, judging whether the position of the first equipment is matched with the position of second equipment carried by the target or not;
in this embodiment, if the first device at the designated location receives the trigger instruction, it indicates that the object suspected of being the target appears at the designated location, and therefore it is necessary to further determine whether the location of the first device matches the location of the second device carried by the target to determine whether the target returns to the designated location.
S103: if the position of the first equipment is matched with the position of second equipment carried by the target, judging that the target returns to the appointed place;
in this embodiment, if the position of the first device matches the position of the second device carried by the target, it indicates that the distance between the first device and the second device is very close, that is, the distance between the target and the designated location is very close, and at this time, the target may be considered to be at the designated location or in the vicinity of the designated location, and thus it may be determined that the target returns to the designated location.
For example, the method for determining whether the target returns to the specified location described in the embodiment can be applied to a specific application environment for determining whether the host returns to home. Specifically, the target is an owner, the designated location is a home of the owner, the first device is installed at the designated location, and the second device is carried by the owner. When a first device in a home senses that an object suspected of an owner appears near the home, it is determined whether a location of the first device in the home and a location of a second device carried with the owner match, and when the locations of the first device and the second device match, it is determined that the owner returns to the home. Of course, the target at this time is not necessarily the owner of the house, and all users carrying the second device are the targets, such as the roommates of the owner, relatives, and the like, and then the scheme provided by the embodiment monitors whether the target returns to the designated place or not, so as to respond to completing the work such as turning on the corresponding household appliance.
It should be noted that the execution subject of each step in the method for determining whether the target returns to the specified location described in this embodiment may be the first device or the second device, which will be described in detail below, and is not limited herein.
In the method for judging whether the target returns to the specified location, provided by the invention, by judging whether the first device in the specified location receives the trigger instruction, under the condition that the first device in the specified location receives the trigger instruction, whether the position of the first device is matched with the position of the second device carried by the target is further judged. If the position of the first device is matched with the position of the second device carried by the target, the target is close to the specified place, and therefore the target can be judged to return to the specified place. Through the mode, the method and the device can accurately judge whether the target returns to the specified place.
Referring to fig. 2, fig. 2 is a flowchart illustrating a second embodiment of a method for determining whether a target returns to a specific location according to the present invention. It is to be understood that the method for determining whether the target returns to the specified location set forth in the present embodiment is not limited to the following steps.
S201: the first equipment judges whether a specified image is detected or not;
in this embodiment, if the first device determines that the designated image is detected, step S202 is executed; if the first device determines that the designated image is not detected, the process continues to step S201.
The first device is located at the appointed place, and the specific form of judging whether the trigger instruction is received is to judge whether the appointed image is detected. Specifically, the first device may have a camera module, and when the target is a person, the designated image is an image of the person, and the first device determines whether the target returns to the designated location, that is, determines whether the designated image detected by the first device is an image of the target. And the first device is always in a state of detecting the image, and when the appointed image appears in the appointed place, the first device triggers the work of further judging whether the appointed image is the target image.
Further, the first device determines whether the specified image is detected by determining whether a human shape or a human face exists in the image detected by the first device.
Of course, in other embodiments of the present invention, the specific form of the first device receiving the trigger instruction is not limited to the form of detecting the specific image. For example, the first device may be an access control device with a doorbell, and when the doorbell is triggered to ring, the first device receives a trigger instruction, and the like, which is not limited herein.
S202: the first equipment judges that a trigger instruction is received;
in this embodiment, if the first device determines that the designated image is detected, the first device determines that the trigger instruction is received.
S203: the first equipment sends an activation instruction to the second equipment to activate the second equipment;
in this embodiment, if the first device determines that the trigger instruction is received, the first device sends an activation instruction to the second device to activate the second device, so as to trigger the first device and the second device to cooperate to confirm whether the target returns to the specified location. The second device is activated after receiving the activation instruction, and then the second device is triggered to cooperate with the first device to confirm whether the target returns to the designated place, so that the second device is prevented from always waiting for cooperating with the first device to confirm whether the target returns to the designated place, and the workload of the second device can be reduced.
Further, the first device may silently push the activation instruction to the second device through VOIP or FCM. The silent pushing process through the VOIP or the FCM is completed in the background of the second device, and meanwhile, the activated second device is also matched with the first device in the background to confirm whether the target returns to the designated place or not, so that the target carrying the second device is not perceived, and the use experience of a user is favorably improved.
The IOS system realizes silent pushing of the activation instruction based on VOIP (Voice over Internet Protocol). And the Android system realizes silent pushing of the activation instruction based on FCM (Cloud Messaging).
S204: the first equipment judges whether to establish second communication connection with the second equipment;
in this embodiment, if the first device determines that the second communication connection with the second device can not be established, step S205 is executed, and if the first device determines that the second communication connection with the second device cannot be established, the process is ended.
Since the transmission mode of the first device sending the activation instruction to the second device is generally unidirectional, that is, from the first device to the second device, and the work of the first device and the second device in cooperation to confirm whether the target returns to the specified location generally requires that there is bidirectional information interaction between the first device and the second device, before the subsequent steps are performed, it is often required that the first device and the second device establish a second communication connection, where the second communication connection provides a channel for bidirectional interaction between the first device and the second device.
Alternatively, the second communication connection may be a P2P (Peer-to-Peer) communication connection, which is not limited herein.
S205: the first equipment judges whether to receive the identity information from the second equipment;
in this embodiment, to confirm that the second device interacting with the first device is indeed the second device carried by the target, so as to prevent malicious interference from a third party, the first device needs to check the identity of the second device, and if the check is passed, it is indicated that the second device interacting with the first device is indeed the second device carried by the target.
Specifically, the first device needs to determine whether to receive identity information from the second device. If the first device receives the identity information from the second device, step S206 is executed; if the first device determines that the identity information from the second device cannot be received, the process is ended.
S206: comparing the identity information with preset identity information;
in this embodiment, after the first device receives the identity information from the second device, the first device compares the identity information with the preset identity information, if the identity information matches the preset identity information, the identity verification is passed, and then step S207 is executed; and if the identity information is not matched with the preset identity information, the identity verification fails, and the process is ended.
The preset identity information is identity information of second equipment carried by a representation target prestored in the first equipment.
S207: judging whether the first equipment establishes a first communication connection with the second equipment and/or judging whether the first equipment is connected with the second equipment through the same local area network;
in this embodiment, after the identity verification is passed, the distance between the first device and the second device needs to be determined to determine whether the specified image detected by the first device is the target image.
Specifically, if it is determined that the first device and the second device establish the first communication connection or that the first device and the second device are connected to the same local area network, step S208 is executed; if it is determined that the first device does not establish the first communication connection with the second device and it is determined that the first device is not connected to the same local area network as the second device, step S209 is performed.
It should be noted that, in this embodiment, the distance between the first device and the second device may be confirmed by determining whether the first device establishes the first communication connection with the second device; or determining the distance between the first device and the second device by judging whether the first device and the second device are connected to the same local area network. Preferably, in this embodiment, the distance between the first device and the second device is determined by determining whether the first device establishes the first communication connection with the second device and also determining whether the first device is connected to the same lan as the second device, where when it is determined that the first device establishes the first communication connection with the second device or that the first device is connected to the same lan as the second device, it is determined that the designated image is the image of the target, and accuracy and success rate of distance determination between the first device and the second device can be greatly improved.
S208: determining an image with the designated image as a target;
in this embodiment, if the first device determines that it establishes the first communication connection with the second device and/or determines that it is connected to the same local area network as the second device, it indicates that the distance between the first device and the second device is very short, that is, the distance between the target and the specified location is very short, and at this time, the target may be considered to be at the specified location or in the vicinity of the specified location, and thus it may be determined that the specified image detected by the first device is the image of the target, that is, it may be determined that the target returns to the specified location. The flow is then ended.
S209: determining that the designated image is not the target image;
in this embodiment, the first device does not establish the first communication connection with the second device, and does not connect to the same local area network with the second device, which means that the distance between the first device and the second device is long, that is, the distance between the target and the specified location is long, and at this time, it may be determined that the target has not returned to the specified location, that is, it may be determined that the specified image detected by the first device is not an image of the target.
Referring to fig. 3, fig. 3 is a flowchart illustrating a method for determining whether a target returns to a designated location according to a third embodiment of the present invention. It is to be understood that the method for determining whether the target returns to the specified location set forth in the present embodiment is not limited to the following steps.
S301: the second equipment judges whether an activation instruction from the first equipment is received or not;
in this embodiment, after the first device detects the designated image, the first device sends an activation instruction to the second device to further trigger the first device and the second device to cooperate to confirm whether the target returns to the designated location. Specifically, the second device determines whether an activation instruction from the first device is received. If yes, determining that the first device receives the trigger instruction, and executing step S302 correspondingly; if not, determining that the first device does not receive the trigger instruction, and continuing to execute step S301.
S302: activating the second device;
in this embodiment, if the second device receives an activation instruction from the first device, it is determined that the first device receives a trigger instruction. Correspondingly, the second device is activated to cooperate with the first device to confirm whether the target returns to the specified location.
S303: judging whether the flag bit represents that the second equipment returns to the specified place or not;
in this embodiment, the second device is provided with a flag bit for indicating whether the second device returns to the specified location, that is, indicating whether the target carrying the second device returns to the specified location. Specifically, when the flag bit does not represent that the second device returns to the designated location, step S304 is executed, that is, a subsequent job of confirming whether the target returns to the designated location in cooperation with the first device is triggered; when the flag bit indicates that the second device returns to the designated location, it indicates that the target has returned to the designated location, and the designated image detected by the first device is not necessarily the image of the target, so that there is no need to perform subsequent operations, and the process is ended.
For example, the first device may be an access control device installed outside a door for detecting whether a specific image appears within a certain range outside the door. When the target returns home, the designated image appears outdoors and is detected by the first device, which indicates that the first device detects that the designated image is not necessarily the image of the target.
S304: the second equipment judges whether to establish second communication connection with the first equipment;
in this embodiment, if the second device determines that the second communication connection with the first device can not be established, step S305 is executed, and if the second device determines that the second communication connection with the first device can not be established, the process is ended.
S305: the second equipment transmits the identity information to the first equipment, so that the first equipment compares the identity information with preset identity information;
in this embodiment, after the second device establishes the second communication connection with the first device, the second device transmits the identity information to the first device, so that the first device compares the identity information with the preset identity information to perform identity verification, and the specific process of the identity verification is described in detail in the above embodiments and is not described herein again.
Further, to further prevent malicious interference of a third party and improve security, before the second device transmits the identity information to the first device, the identity information is further encrypted, for example, by using AES (Advanced Encryption Standard).
S306: the distance between the first equipment and the second equipment is confirmed by matching with the first equipment;
in this embodiment, the manner in which the second device cooperates with the first device to determine the distance between the first device and the second device may specifically be to determine the distance between the first device and the second device by determining whether the first device establishes the first communication connection with the second device and/or determining whether the first device is connected to the same local area network as the second device, which is not described herein again.
It should be noted that, after the target is determined to return to the specified location, the second device modifies the flag bit to indicate that the second device returns to the specified location, that is, to indicate that the target returns to the specified location. Of course, the target may operate on the second device and modify the flag to characterize the second device as returning to the designated location. When the target leaves the designated location again, the target needs to modify the flag bit to an uncharacterized second device to return to the designated location in person, or to implement the modification by other means, which is not limited herein.
Moreover, the second device may install an APP (Application program) to implement the method for determining whether the target returns to the specified location as set forth in the foregoing embodiments. Of course, the second device itself may be integrated with a function of determining whether the target returns to the specified location, which is not limited herein.
A scheme for confirming the distance between the first device and the second device by determining whether the first device and the second device are connected to the same local area network will be described below.
In this embodiment, the coverage area of the local area network is usually small, and if the first device and the second device are connected to the same local area network, it is indicated that the first device and the second device are in the coverage area of the same local area network, that is, the distance between the first device and the second device is considered to be very close. Specifically, the first device interacts with the second device through the second communication connection, so as to determine whether the first device or the second device is connected to the same local area network. The local area network may be a WiFi network or a bluetooth network, and it is determined whether the first device and the second device are connected to the same local area network, that is, whether the first device and the second device are connected to the local area network radiated by the same network source. The local area network is taken as an example of a WiFi network for explanation, which is only needed for discussion and is not limited herein.
Referring to fig. 4, fig. 4 is a flowchart illustrating a first embodiment of a specific manner of determining whether a first device and a second device are connected to the same lan according to the present invention.
In an embodiment, the process of determining whether the first device and the second device are connected to the same local area network may include the following steps.

S504: and determining that the first device is not connected with the same WiFi network as the second device.
The following describes a scheme for confirming a distance between a first device and a second device by determining whether the first device establishes a first communication connection with the second device.
In this embodiment, when the distance between the first device and the second device is short, the first communication connection is allowed to be established between the first device and the second device, and therefore, the distance between the first device and the second device can be confirmed by determining whether the first communication connection is established between the first device and the second device. It is to be understood that the first communication connection may be a bluetooth communication connection or a WiFi communication connection, and the first communication connection is a bluetooth communication connection for example, which is only required for discussion and not limiting.
Referring to fig. 6, fig. 6 is a flowchart illustrating an embodiment of a specific method for determining whether a first communication connection is established between a first device and a second device according to the present invention.
In an embodiment, the process of determining whether the first device establishes the first communication connection with the second device may include the following steps.
S601: the first device broadcasts bluetooth information and the second device searches for and attempts to connect to the bluetooth information broadcast by the first device.
S602: judging whether the first equipment establishes Bluetooth connection with the second equipment or not;
in this embodiment, if the first device establishes a bluetooth connection with the second device, step S603 is executed; if the first device does not establish a bluetooth connection with the second device, step S604 is executed. The main body performing the determination in step S602 may be the first device or the second device, which is not limited herein.
Further, it may be determined whether the first device establishes a bluetooth connection with the second device within a preset time. If the Bluetooth connection is established between the first device and the second device within the preset time, it can be judged that the first communication connection is established between the first device and the second device; if the first device does not establish the bluetooth connection with the second device within the preset time, the first device stops broadcasting the bluetooth information continuously, and the second device stops searching the bluetooth information broadcasted by the first device, which indicates that the distance between the first device and the second device is longer. The preset time can be set by a user according to needs. By the method, time consumption of the judging process is reduced, and workload of the first equipment and the second equipment can be reduced.
S603: and determining that the first communication connection is established between the first device and the second device. The flow is then ended.
