Fig. 2 is a flow chart of the method for preventing the lost of the present invention applied to the server according to the preferred embodiment. The order of the steps in the flow chart may be changed and some steps may be omitted according to different needs.

S10, when the alarm signal of the master device 24 is acquired, the server 1 acquires the feature information of the second user of the slave device 25.

In at least one embodiment of the present invention, the server 1 receives the feature information of the first user and the feature information of the second user of the main device 24, which are collected by the collecting device 4, and stores the feature information and the feature information in the database of the server 1.

In at least one embodiment of the invention, the first user comprises a guardian, for example: parents, children, etc. The second user comprises a person under guardianship, for example: the elderly, children, etc.

In at least one embodiment of the present invention, the feature information of the first user and/or the feature information of the second user includes, but is not limited to, one or more of the following combinations: fingerprint features, clothing features (e.g., clothing color, style, etc.), height features, accessory features, and the like.

Wherein the collecting of the fingerprint feature is decided by the first user whether or not to proceed due to problems related to privacy protection. The door control device 5 mainly collects the fingerprint characteristics of the first user and the fingerprint characteristics of the second user as matched characteristic information to determine the permission.

In at least one embodiment of the present invention, the server 1 communicates with the access control device 5, when the access control device 5 detects that at least one user similar to the characteristic information of the second user passes through the server, the at least one user and at least one other user corresponding to the at least one user are prompted to enter fingerprints, and the acquisition device 4 acquires at least two fingerprints in real time and sends the at least two fingerprints to the access control device 5 communicating with the server 1. The server 1 acquires at least two fingerprints sent by the access control device 5, matches the acquired at least two fingerprints with fingerprints in a database of the server 1 to determine whether the at least two fingerprints are matched fingerprints, and sends a prohibition command to the access control device 5 to prohibit at least two users corresponding to the at least two fingerprints from leaving a monitoring area corresponding to the server 1 when the at least two fingerprints are not matched fingerprints; and when the at least two fingerprints are matched fingerprints, sending an allowing command to the access control device 5 to allow at least two users corresponding to the at least two fingerprints to leave the monitoring area corresponding to the server 1.

Similarly, when a user wants to pass through the access control device 5, if the server 1 detects that the user does not have the paired feature information collected in advance in the database, the user may use another method (e.g., using an electronic ticket, etc.) to make the server 1 send an allow command to the access control device 5 to allow the user to leave the monitoring area (e.g., the scenic spot) corresponding to the server 1. For example, embodiment one.

The first embodiment is as follows:

when the user enters a scenic spot, the adult A selects whether to enter the fingerprint, if so, the adult A and the child B enter the fingerprint together, the server 1 can pair and bind the two fingerprints, and the paired fingerprints are stored in a database of the server 1. When the adult a and the child B want to leave a monitoring area corresponding to the server 1 through the access control device 5, namely, when the adult a and the child B exit a scene, the acquisition device 4 acquires the fingerprint of the adult a and the fingerprint of the child B, and sends the fingerprint of the adult a and the fingerprint of the child B to the access control device 5, the access control device 5 is in communication with the server 1, the access control device 5 sends the fingerprint of the adult a and the fingerprint of the child B to the server 1, the server 1 acquires the fingerprint of the adult a and the fingerprint of the child B sent by the access control device 5, and matches the acquired fingerprint of the adult a and the acquired fingerprint of the child B with the fingerprint in the database to determine whether the fingerprint of the adult a and the fingerprint of the child B are matched fingerprints. When the fingerprint of the adult a and the fingerprint of the child B are not matched fingerprints, the server 1 sends a prohibition command to the access control device 5 to prohibit the adult a and the child B from leaving the scenic spot; when the fingerprint of the adult a and the fingerprint of the child B are paired fingerprints, the server 1 sends an allowing command to the access control device 5 to allow the adult a and the child B to leave the scenic spot. Therefore, when the person A and the child B go out of the scene, the unlocking and the door opening can be realized only if the adult A and the child B input matched fingerprints at the same time. Prevent other people from taking away children and ensure the safety of children. Preferably, if one of the users corresponding to the paired fingerprints is to leave the scenic spot separately or with another person, at this time, confirmation and authorization of the first user need to be obtained, that is, authorization is issued after the first user performs fingerprint confirmation, and then the first user is allowed to leave.

Similarly, if the user C chooses not to enter a fingerprint when entering the scenic spot, the user C can directly enter the scenic spot with an electronic ticket. When the user C wants to pass through the access control device 5 when going out of the scene, if the server 1 detects that the user C does not have a paired fingerprint collected in advance in the database, the user C can use an electronic ticket to swipe out the access control device 5 without any person for authorization. Preferably, when entering the scenic spot, a user without a child does not need to enter a fingerprint, the fingerprint entering is a user with a child conveniently, the first user selects whether to enter the fingerprint, so that further safety guarantee for the child is realized, the child cannot be taken out of the scenic spot by other people at will, and the user entering the entrance guard device 5 in a fingerprint entering mode cannot use the electronic ticket to enter and exit the scenic spot.

It should be noted that, in other embodiments, the second user may also correspond to at least one other user, where the at least one other user is a guardian or a companion person who is equivalent to the authority of the first user. For example: when the child a is the second user, the parent a and the parent B may simultaneously be guardians of the child a. Like this, when collection device 4 carries out the collection of characteristic, will gather children a's characteristic information parent A's characteristic information reaches parent B's characteristic information, and will children a's characteristic information parent A's characteristic information reaches parent B's characteristic information stores the database, as the characteristic information of pairing.

Further, in order to enhance privacy protection and ensure privacy security of the first user and the second user, after the server 1 determines that the first user and the second user leave the scenic spot according to the record of the access control device 5, the server 1 removes the feature information of the first user and the feature information of the second user from the database. The feature information mainly includes fingerprint features of the first user, fingerprint features of the second user and the like.

For example: after the adult a and the child B pass through the access control device 5, the server 1 can know that the adult a and the child B leave the scenic spot according to the record of the access control device 5, and then the server 1 removes the fingerprint of the adult a and the fingerprint of the child B from the database to ensure the privacy of the user.

S11, the server 1 obtains the position of the master device 24 when alarming.

In at least one embodiment of the present invention, an alarm is issued when the distance between the first user and the second user exceeds a preset threshold (e.g. 5 meters), or the first user and the second user lose contact, or the terminal device 2 falls off. Generally, the distance information and the position information of the master device 24 and the slave device 25 are continuously fed back, and the master device 24 and the server 1 receive the distance information and the position information. Preferably, in order to reduce the memory usage, the next distance information and the location information may be overwritten with the previous distance information and the previous location information. And sending an alarm once the distance information and the position information are not received or the received distance is greater than the preset threshold value. To ensure safety and utility, an alarm will be issued on the master device 24. If the main device 24 has a problem, the server 1 sends an alarm, feeds back the nearest position information to the nearest manual monitoring place, and carries out manual processing and debugging on the device. Other parts of the general equipment have problems and do not affect the alarm device 240, so that when one equipment has problems, the equipment cannot receive data and continues to send out error warning signals. If one of the devices has a problem, the other device still has data to be transmitted to the server 1, but the data cannot be transmitted to the other device, and in this case, after an alarm is given, the specific position of the other device can be obtained through the server 1.

In at least one embodiment of the present invention, the master device 24 and the server 1 receive the distance information and the location information because the distance information and the location information of the master device 24 and the slave device 25 are continuously fed back therebetween. Therefore, after the server 1 receives the alarm signal, the last acquired position information is automatically used as the position of the master device 24 when the alarm is given.

In other embodiments, the manner of the server 1 obtaining the position of the master device 24 at the time of alarm may also be one or a combination of the following manners:

(1) when the master device 24 gives an alarm to the server 1, the master device 24 simultaneously sends the position of the master device 24 when giving the alarm to the server 1, and the server 1 receives the current position, that is, the position of the master device 24 when giving the alarm is obtained.

(2) After acquiring the alarm signal of the master device 24, the server 1 prompts the master device 24 to send the position of the master device 24 when the alarm is given to the server 1, and the server 1 receives the current position, that is, the position of the master device 24 when the alarm is given is acquired.

(3) The server 1, while acquiring the alarm signal of the master device 24, locates the position of the master device 24 by using a GPS (Global Positioning System), LBS (Location Based Service), or other manners, and determines the located position as the position of the master device 24 when the alarm signal is given.

S12, the server 1 determines a target monitoring area according to the current position.

In at least one embodiment of the present invention, the server 1 determines, in a monitoring area corresponding to the server 1, an area within a preset range with the current position as a center as a target monitoring area.

The preset range may be a circular area with the current position as a center and a first preset value as a radius, or a square area with the current position as a center and a second preset value as a diagonal, which is not limited herein.

Preferably, in this embodiment, the monitoring area is within the whole scenic spot.

S13, the server 1 acquires image information in the target monitoring area by the imaging device 3 communicating with the server 1.

In at least one embodiment of the present invention, the server 1 is in communication with the camera 3, and the camera 3 includes at least one camera for capturing images in a monitoring area corresponding to the server 1 to provide video data and image information.

In at least one embodiment of the present invention, after the server 1 receives the alarm signal, that is, when the second user needs to be found, an image capturing manner is adopted, that is, the server 1 controls the camera 3 to start a camera in the target monitoring area for capturing, and controls the camera 3 to send captured image information to the server 1, and the server 1 receives the captured image information, that is, obtains the image information in the target monitoring area.

S14, according to the image information in the target monitoring area and the feature information of the second user, the server 1 searches for the second user and determines the location information of the second user.

In at least one embodiment of the present invention, the searching, by the server 1, the second user according to the image information in the target monitoring area and the feature information of the second user, and determining the location information of the second user includes:

the server 1 determines a target person according to the image information in the target monitoring area and the feature information of the second user, sends the image information of the target person to the main device 24, and the server 1 prompts the first user of the main device 24 to confirm whether the target person is the second user.

When the server 1 receives a signal sent by the first user through the main device 24 to confirm that the target person is the second user, the server 1 tracks the target person through the camera 3, determines the location information of the second user, and sends a notification instruction to the user device of the staff closest to the location information of the second user, so that the staff can find the second user.

When the server 1 receives a signal sent by the first user through the host device 24 to confirm that the target person is not the second user, the server 1 sends image information, of which the similarity between the feature information of the second user and the feature information of the target monitoring area is higher than a preset value, to the host device 24 for the first user to confirm.

When the server 1 receives a signal sent by the first user through the master device 24 to confirm that the second user is not present in the target monitoring area, the server 1 obtains image information shot by the camera 3, and sends the image information shot by the camera 3 to the master device 24 for the first user to confirm.

In at least one embodiment of the present invention, when the second user is found, the server 1 may send a prompt message to the terminal device 2 to prompt the first user to claim the second user to a specified place.

Example two:

when entering the scene, adult a selects whether to input the fingerprints of the adult and child b or not, and matches the information. Due to the personal privacy involved, the guest's choice needs to be respected. But the fingerprint is not recorded, the relationship between children and adults can not be distinguished according to the fingerprint when the children and adults are out of the scenic spot, and one layer of protection is omitted. After the tourist leaves the scenic spot, the scenic spot system automatically clears personal information such as the fingerprint reserved before so as to ensure privacy.

When an adult a sends an alarm signal through the main device 24 to seek help of a scenic spot, the scenic spot receives the alarm signal to obtain positioning information of the main device 24, the camera shooting seeking is started by taking the position of the main device 24 as a center, the camera is connected with the server 1, the server 1 preferably pushes camera shooting information suitable for at least one characteristic and positions a manual monitoring platform according to personal characteristic information such as the height, clothes color and the like of a lost child according to camera shooting obtained by the camera, and sends the camera shooting information and the positioning information to the main device 24 for confirmation. If the object is confirmed to be the target, the object is locked, cameras along the way are controlled to track and shoot the object, meanwhile, nearest workers are informed to search, and after the object is found, adults a are informed to a specified place to conduct claiming. If the camera which is pushed preferentially is not determined as yes by the master device 24, which indicates that the camera is not a child to be found, the server 1 will push preferentially a camera which is determined to be a child, for example, from a height factor. Therefore, images of children are preferentially pushed, and the manual searching range is reduced. If not, all the images in the scenic spot need to be screened.

Each exit is watched by workers, and meanwhile, an access control system is arranged, so that children who do not carry the electronic ticket can go out. The fingerprint of children and the fingerprint of adults can pass through the fingerprint matching device after the fingerprints of children and adults are matched. This also prevents the risk of a child being taken away by a stranger.

In summary, the present invention can obtain the feature information of the second user of the secondary device when the alarm signal of the primary device is obtained; acquiring the position of the master equipment when alarming; determining a target monitoring area according to the current position; acquiring image information in the target monitoring area through a camera device communicated with the server; and searching the second user according to the image information in the target monitoring area and the characteristic information of the second user, and determining the position information of the second user. Therefore, the invention can realize multiple protection of the person under guardianship in the monitoring area, effectively prevent the person under guardianship from missing and improve the safety.

Fig. 3 is a flowchart illustrating a preferred embodiment of the method for preventing loss according to the present invention applied to a terminal device. The order of the steps in the flow chart may be changed and some steps may be omitted according to different needs.

S20, the terminal device 2 monitors distance information between the master device 24 and the slave device 25.

In at least one embodiment of the present invention, the terminal device 2 monitors the distance between the main device 24 and the sub-device 25 in real time, and records the distance information.

In at least one embodiment of the present invention, the distance information and the position information of the master device 24 and the slave device 25 are continuously fed back in real time, and the master device 24 and the server 1 receive the distance information and the position information. Preferably, in order to reduce the memory usage, the next distance information and the location information may be overwritten with the previous distance information and the previous location information.

In at least one embodiment of the present invention, the terminal device 2 includes the master device 24 and the slave device 25. The master device 24 communicates wirelessly with the slave device 25. The master device 24 includes an alarm 240.

In at least one embodiment of the present invention, the manner in which the master device 24 communicates wirelessly with the slave device 25 includes, but is not limited to: wireless communication via bluetooth, wireless communication via a wireless network, etc.

S21, when it is monitored that the distance information is in an abnormal state, the terminal device 2 alarms through the main device 24 to prompt the first user of the main device 24 to prevent the second user of the auxiliary device 25 from being lost.

In at least one embodiment of the present invention, the condition that the terminal device 2 monitors that the distance information is in an abnormal state includes:

(1) when the terminal device 2 monitors that the distance information is greater than or equal to a preset value, the terminal device 2 determines that the distance information is in an abnormal state. The preset value may be set by the first user, may also be set by a related worker, and may also be default factory setting of the terminal device 2, which is not limited herein.

For example: when the terminal device 2 monitors that the distance information is greater than or equal to a preset value of 5 meters, the terminal device 2 determines that the distance information is in an abnormal state.

(2) And when the terminal equipment 2 cannot monitor the distance information, the terminal equipment 2 determines that the distance information is in an abnormal state.

For example: when the main device 24 or the auxiliary device 25 of the terminal device 2 fails, or a signal of an area where the terminal device 2 is located is not good, or the main device 24 is in a power shortage state or the auxiliary device 25 is in a power shortage state, the terminal device 2 cannot monitor the distance information, and at this time, the terminal device 2 determines that the distance information is in an abnormal state.

In at least one embodiment of the present invention, when the terminal device 2 monitors that the distance information is in an abnormal state, the terminal device 2 alarms through the main device 24 to prompt the first user of the main device 24 to prevent the second user of the auxiliary device 25 from being lost.

In at least one embodiment of the present invention, after the primary device 24 prompts the first user of the primary device 24 to prevent the second user of the secondary device 25 from being lost, the first user selects whether to alert the server 1.

In at least one embodiment of the present invention, the terminal device 2 sends an alarm signal to the server 1 in communication with the terminal device 2, so that the server 1 searches for a second user corresponding to the secondary device 25 in its corresponding monitoring area.

Example three:

after entering the scenic spot, the adult a and the child b wear the terminal device 2, wherein the adult a wears the main device 24, and the child b wears the auxiliary device 25. The main device 24 and the auxiliary device 25 are used in a matched manner, are powered by solar energy and are connected through a wireless network. The distance between the main device 24 and the auxiliary device 25 is measured at every moment, related data are reserved, and if the distance is found to exceed a preset range (such as 3 meters), or distance data cannot be obtained, the main device 24 gives an alarm to remind an adult a to avoid a child b from being lost. Specifically, if the instant measurement data cannot be obtained, it indicates that the terminal device 2 is out of power or has a fault, or the signal is not good and is not connected, but the terminal device 2 preferentially ensures sufficient power consumption of the alarm device 240 in the absence of power.

Fig. 4 is a functional block diagram of a server in accordance with a preferred embodiment of the system for preventing loss of contact. The system 11 of the server 1 includes an acquisition module 100, a determination module 101, and a search module 102. The module referred to herein is a series of computer program segments capable of being executed by a processing device and of performing a fixed function, and is stored in a memory device. In the present embodiment, the functions of the modules will be described in detail in the following embodiments.

When the obtaining module 100 obtains the alarm signal of the master device 24, the obtaining module 100 obtains the feature information of the second user of the slave device 25, and stores the feature information in the database of the server 1.

In at least one embodiment of the present invention, the obtaining module 100 receives the feature information of the first user and the feature information of the second user of the main device 24, which are collected by the collecting device 4, and stores the feature information and the feature information in the database of the server 1.

The first embodiment is as follows:

when the user enters a scenic spot, the adult A selects whether to enter the fingerprint, if so, the adult A and the child B enter the fingerprint together, the server 1 can pair and bind the two fingerprints, and the paired fingerprints are stored in a database of the server 1. When the adult a and the child B want to leave a monitoring area corresponding to the server 1 through the access control device 5, that is, when going out of a scene, the acquisition device 4 acquires the fingerprint of the adult a and the fingerprint of the child B and sends the fingerprint of the adult a and the fingerprint of the child B to the access control device 5, the access control device 5 is in communication with the server 1, the access control device 5 sends the fingerprint of the adult a and the fingerprint of the child B to the server 1, the acquisition module 100 acquires the fingerprint of the adult a and the fingerprint of the child B sent by the access control device 5 and matches the acquired fingerprint of the adult a and the acquired fingerprint of the child B with the fingerprint in the database to determine whether the fingerprint of the adult a and the fingerprint of the child B are matched fingerprints. When the fingerprint of the adult a and the fingerprint of the child B are not matched fingerprints, the server 1 sends a prohibition command to the access control device 5 to prohibit the adult a and the child B from leaving the scenic spot; when the fingerprint of the adult a and the fingerprint of the child B are paired fingerprints, the server 1 sends an allowing command to the access control device 5 to allow the adult a and the child B to leave the scenic spot. Therefore, when the person A and the child B go out of the scene, the unlocking and the door opening can be realized only if the adult A and the child B input matched fingerprints at the same time. Prevent other people from taking away children and ensure the safety of children. Preferably, if one of the users corresponding to the paired fingerprints is to leave the scenic spot separately or with another person, at this time, confirmation and authorization of the first user need to be obtained, that is, authorization is issued after the first user performs fingerprint confirmation, and then the first user is allowed to leave.

Similarly, if the user C chooses not to enter a fingerprint when entering the scenic spot, the user C can directly enter the scenic spot with an electronic ticket. When the user C wants to go through the access control device 5 when going out of the scene, if the server 1 detects that the user C does not have the paired fingerprint collected in advance in the database, the user C can use the electronic ticket to swipe the access control device 5 without any person for authorization. Preferably, when entering the scenic spot, a user without a child does not need to enter a fingerprint, the fingerprint entering is a user with a child conveniently, the first user selects whether to enter the fingerprint, so that further safety guarantee for the child is realized, the child cannot be taken out of the scenic spot by other people at will, and the user entering the entrance guard device 5 in a fingerprint entering mode cannot use the electronic ticket to enter and exit the scenic spot.

For example: after the adult a and the child B pass through the access control device 5, the server 1 can know that the adult a and the child B leave a scenic spot according to the record of the access control device 5, and then the server 1 removes the fingerprint of the adult a and the fingerprint of the child B from the database to ensure the privacy of the user.
