Description

Technical Field

[0001] The present disclosure relates to the field of key management, and particularly to a keychain, a keychain management device, a keychain management method, a keychain management system, and a computer-readable storage medium. Background Art

[0002] Nowadays, many rental companies or intermediary companies need to keep the keys of many leased properties and real estates. The most typical example is that many real estate owners will entrust real estate intermediaries to handle the sale or rental of houses. Among them, the keys of the houses are handed over to the real estate intermediaries for management, and the brokers are authorized to carry the keys to show the houses.

[0003] However, personal custody of keys by authorized brokers may lead to various problems and risks. For example, the keys are easily lost and cannot be retrieved after being lost, the keys and the users of the keys cannot be monitored and tracked, and the keys are borrowed by unauthorized personnel, etc. These problems and risks may cause huge economic losses to the owners and have a serious negative impact on the intermediary companies.

[0004] To avoid or mitigate the above problems or risks, centralized management of these keys is required. Many methods and devices for centralized management of keys have been disclosed in the prior art. For example, CN109741504A discloses a key management box, a keychain, a key management device, and a key management method capable of centralized management of keys, EP2597626A1 discloses a key management box, CN106228661A discloses a portable key management box, a key management system, and a usage method, and CN107997414A discloses a modular key cabinet based on RFID technology. However, the devices, systems, and methods for centralized management of keys disclosed in these prior arts still have the above problems and risks.

[0005] Therefore, there is a need to provide improved devices, systems, and methods for centralized management of keys. Summary of the Invention

[0064] According to a first aspect of the present disclosure, as Figures 1 to 6 shown, a keychain 100 is provided. The keychain 100 is configured to removably hold one or more keys 110. The keychain 100 includes: a key holder 120, which is generally U-shaped and has a first leg 121, a second leg 122, and a connecting portion 123 connecting the first leg 121 and the second leg 122; a housing 130, to which the key holder 120 is connected and which is movable relative to the housing 130 between a fixed position (as Figure 1 , Figure 5 and Figure 6 shown) and a disengaged position (as Figure 3 and Figure 4 shown). In the fixed position, the first leg 121 and the second leg 122 of the key holder 120 are both inserted into the housing 130. In the disengaged position, the second leg 122 of the key holder 120 can be disengaged from the housing 130 while the first leg 121 remains within the housing 130. It should be understood that in the disengaged position, the first leg 121 and the second leg 122 of the key holder 120 may also both be disengaged from the housing 130.

[0065] The keychain 100 further includes a key holder locking device 140, which is movable between a locked position and a released position. In the locked position (see Figure 5 and Figure 6 ), the key holder 120 is locked to the housing 130. In the released position (see Figure 3 and Figure 4 ), the key holder 120 can be moved from the housing 130.

[0066] It should be understood that although in Figures 1 to 6 , the key holder locking device 140 is located within the housing 130, the key holder locking device 140 may also be located outside the housing 130, for example, provided on the key holder 120. The present disclosure does not limit the position of the key holder locking device 140 as long as it can lock and release the key holder 120 relative to the housing 130.

[0067] As Figures 2 to 6As shown, the key holder locking device 140 includes an actuator 141 and a locking member 142 that can be driven by the actuator 141 to move between the locking position and the release position. The first leg 121 is provided with a locking member engaging portion 121a that cooperates with the locking member 142. In this embodiment, the locking member engaging portion 121a is a smooth recess, and the portion of the locking member 142 that cooperates with the locking member engaging portion 121a is a smooth convex portion complementary to the shape of the smooth recess. In the locking position (see Figure 5 and Figure 6 ), the smooth convex portion of the locking member 142 cooperates with the locking member engaging portion 121a to prevent the key holder 120 from moving from the fixed position (such as Figure 1 , Figure 5 and Figure 6 shown) to the disengaged position (such as Figure 3 and Figure 4 shown). In the release position (see Figure 3 and Figure 4 ), the smooth convex portion of the locking member 142 is separated from the locking member engaging portion 121a to allow the key holder 120 to move from the (such as Figure 1 , Figure 5 and Figure 6 shown) to the disengaged position (such as Figure 3 and Figure 4 shown).

[0068] In this embodiment, the locking member engaging portion 121a is provided at a position on the first leg 121 that is opposite to the locking member 142 when the key holder 120 is in the fixed position (such as Figure 1 , Figure 5 and Figure 6 shown), so that the key holder 120 can be locked by the key holder locking device 140 only when the first leg 121 and the second leg 122 are respectively inserted into the corresponding holes in the housing 130 and reach their fixed positions. This avoids possible mislocking situations, such as when only the first leg 121 is inserted into the corresponding hole in the housing 130 and the second leg 122 is located outside the housing 130 (since in the Figure 3 and Figure 4 shown disengaged position, the key holder 120 can rotate about the first leg 121 as a pivot axis), even when the depth of insertion of the first leg 121 into the housing 130 is the same as Figure 5 and Figure 6The depth shown in is the same. Since the locking member engaging portion 121a does not face the smooth convex portion of the locking member 142, the key holder 120 cannot be locked in the housing 130. This can prompt the user that the key locking member 120 is not properly locked and that its position and angle need to be further adjusted for proper locking.

[0069] It should be noted that here "smooth" means that the cross-sections of the locking member engaging portion 121a and the smooth convex portion are circular, elliptical, parabolic or other non-edged shapes, rather than rectangular, triangular or other shapes with edges. By providing the smooth recess (locking member engaging portion 121a) and the smooth convex portion, the key holder 120 can be firmly locked to the housing 130, and at the same time, it can prevent the locking member 142 from being stuck in the locking member engaging portion 121a due to an external force pulling the key holder 120.

[0070] Although Figures 2 to 6 it is shown that only the first leg 121 is provided with the locking member engaging portion 121a for locking the key holder 120 in the housing 130, it should be understood that a similar locking member engaging portion can also be provided on the second leg 122.

[0071] As Figures 2 to 6 shown, the actuator 141 is a rotary driver, such as an electric motor. The rotary driver drives the locking member 142 through at least a part of its cam surface 141a to move the locking member 142 between the locking position and the release position. It should be understood that the actuator 141 can also be a linear driver, such as a linear motor, to directly drive the locking member 142 to move between the locking position and the release position.

[0072] As Figure 4 and Figure 6 shown, the key holder locking device 140 further includes a pressing element 143 for pressing the locking member 142 toward the first leg 121 provided with the locking member engaging portion 121a. The pressing element 143 includes a push rod 143a, a baffle 143b provided at one end of the push rod 143a and in contact with the locking member 142, and an elastic element 143c provided around the push rod 143a. As Figure 5 and Figure 6 shown, the actuator 141 drives the pressing element 143 through a part of its cam surface 141a. The pressing element 143 pushes the locking member 142 so that the smooth convex portion of the locking member 142 cooperates with the locking member engaging portion 121a, thereby positioning the locking member 142 at the locking position; when the actuator 141 rotates counterclockwise from the Figure 6 position shown in Figure 4When in the position shown, a part of the cam surface 141a no longer applies a force to the pushing element 143, so the baffle 143b no longer applies a force to the locking element 142, allowing the locking element 142 to separate from the locking element mating portion 121a, thereby permitting the key holder 120 to move to the disengaged position.

[0073] It should be understood that although Figure 4 and Figure 6 show the pushing element 143 and the locking element 142 as two separate elements, the pushing element 143 and the locking element 142 can also be an integral element. In addition, the elastic element 143c can be omitted, as the elastic element 143c is used to increase or decrease the pushing force of the push rod 143a on the locking element 142.

[0074] The key fob 100 further includes a key holder ejection device (not shown) that elastically pushes the key holder 120 along the direction of ejecting the key holder 120 from the housing 130, such that when the key holder locking device 140 is in the release position for releasing the key holder 120, the key holder ejection device can push the key holder 120 out of the housing 130. For example, the key holder ejection device can be a spring that is compressed by the first leg 121 and / or the second leg 122 when the key holder 120 is in a fixed position (as shown in Figure 1 , Figure 5 and Figure 6 ).

[0075] As shown in Figure 2 , the key fob 100 according to the present disclosure further includes a controller 150 that is disposed within the housing 130 and is electrically connected and / or communicatively connected to the key holder locking device 140 to control the movement of the key holder locking device 140 between the locked position and the release position.

[0076] According to the present disclosure, the key fob 100 further includes a key holder position sensor 160 that is configured to at least detect the fixed position and the disengaged position of the key holder 120 and send a signal indicating the detected position of the key holder 120 to the controller 150. For example, the key holder position sensor 160 can determine whether the key holder 120 is in the fixed position or the disengaged position by detecting the position of the first leg 121 and / or the second leg 122.

[0077] According to the present disclosure, the keychain 100 may further include a key retainer locking device position sensor (not shown), which is configured to at least detect the locked position and the released position of the key retainer locking device 140, and send a signal indicating the detected position of the key retainer locking device 140 to the controller 150.

[0078] As a possible embodiment, the keychain 100 further includes a positioning device (not shown) for detecting the position of the keychain 100, and the positioning device sends the detected position information of the keychain to the controller 150. It should be understood that the positioning device may include, but is not limited to, a GPS system, a Beidou system, a GLONASS system (the "GLONASS" system), or a Galileo system (the "Galileo" system), and may also be a device for obtaining position information based on a communication base station, WiFi, etc.

[0079] In addition, in order to enable the keychain 100 to receive external instructions and send its own data information (such as position information) to a remote management system, for example, the keychain 100 may further include a wired communication device and / or a wireless communication device electrically connected to the controller 150, and a power source (such as a battery) for powering the keychain 100.

[0080] As a possible implementation manner, the keychain 100 may further include a housing anti-tampering component (not shown), which is permanently damaged in response to the housing 130 being opened, and / or sends a signal indicating that the housing 130 has been unauthorizedly opened to the controller 150. As a possible implementation manner, the housing anti-tampering component may also be configured to prevent the first housing component 131 and the second housing component 132 of the housing 130 from being assembled together again after the housing anti-tampering component is permanently damaged.

[0081] As a possible implementation, the housing may include a first housing member 131 and a second housing member 132. The housing anti-tampering member includes a first housing anti-tampering member and a second housing anti-tampering member respectively disposed on the first housing member 131 and the second housing member 132. When the first housing member 131 and the second housing member 132 are connected to each other to form a closed housing 130, the first housing anti-tampering member and the second housing anti-tampering member are snap-connected together, so that when the first housing member 131 and the second housing member 132 are separated from each other, at least one of the first housing anti-tampering member and the second housing anti-tampering member is permanently damaged. For example, the first housing anti-tampering member and the second housing anti-tampering member may be hooks that can be snap-connected to each other along the direction in which the first housing member 131 and the second housing member 132 are snapped together, so that when the first housing member 131 and the second housing member 132 are separated in a direction opposite to the snapping direction, at least one of the first housing anti-tampering member and the second housing anti-tampering member will break.

[0082] Similarly, the keychain 100 may further include a key holder anti-tampering member (not shown). The key holder anti-tampering member is permanently damaged in response to the key holder 120 being moved to the disengaged position when the key holder locking device 140 is in the locked position, and / or sends a signal indicating that the key holder has been unauthorizedly opened to the controller 150.

[0083] In addition to being able to determine whether the housing and the key holder have been unauthorizedly opened through the above-mentioned housing anti-tampering member and key holder anti-tampering member, as an alternative or supplement, the controller 150 may be configured to determine that the key holder 120 has been unauthorizedly opened in response to receiving the signal that the key holder 120 is in the disengaged position sent by the key holder position sensor and the signal that the key holder locking device 140 is in the locked position sent by the key holder locking device position sensor, and send a warning signal to the administrator of the keychain 100 or a remote server.

[0084] It should be understood that the structures and working principles of the above various sensors are well known to those skilled in the art, so the structures and working principles of these sensors will not be described in detail here.

[0085] As a possible implementation, the key fob 100 may further include a visual indicator (e.g., one or more indicator lights that can emit different colors of light) and / or an auditory indicator (e.g., a speaker) electrically connected to the controller 150 for communicating notifications related to the status of the key fob 100. The status of the key fob 100 includes, but is not limited to: the key holder 120 and / or the housing 130 of the key fob 100 being unauthorizedly opened, which is indicated, for example, by a constantly lit red indicator light; the battery of the key fob 100 being low, which is indicated, for example, by a flashing green indicator light; the key fob 100 being in an abnormal usage state, for example, the position of the key fob 100 deviating from a predetermined usage position, and such an abnormal usage state can be indicated by a flashing red indicator light, and so on. For the statuses that may cause serious consequences among the above statuses (such as the key holder 120 and / or the housing 130 being unauthorizedly opened, or the position of the key fob 100 deviating from the predetermined usage position, etc.), while indicating by a red indicator light, a sharp noise or voice broadcast can also be used to inform people near the key fob 100.

[0086] In addition to indicating various statuses of the key fob 100 through the visual indicator and / or the auditory indicator as described above, various statuses and information of the key fob 100 can also be transmitted to a remote server, the administrator of the key fob 100, the owner of the key carried by the key fob 100, etc. through a wired or wireless network connection, so as to record and view the status and information of the key fob 100. For example, the administrator of the key fob 100, the owner of the key carried by the key fob 100, etc. can view the status of the key fob 100, the location where it is located, the information of the broker who is borrowing the key fob in real time, and so on.

[0087] In addition, the key fob 100 may further include a memory (not shown). In addition to storing the identity information for uniquely identifying the key fob, the memory may also store other information associated with the key fob. For example, the memory of the key fob 100 may store the usage information of the key fob. The usage information is, for example, used to indicate whether the key fob is for holding the key of a house for rent or the key of a house for sale. Through these usage information, different control rules can be formulated for different key fobs, such as lending rules, return rules, and so on. For another example, the memory of the key fob 100 may also store information related to the permitted usage time of the key fob. Thus, it is possible to prevent the key fob 100 from being used (e.g., lent out) during non-usage time. For yet another example, the memory may also store information related to the key on the key holder. The information related to the key on the key holder is, for example, the ID of the key, such as the ID of a specific room in a specific building in a specific community or the ID of the store where the key is located, and so on.

[0088] According to a second aspect of the present disclosure, as Figures 7 to 15 shown, a keychain management device 200 is provided for managing the above-mentioned keychain 100. The keychain management device 200 includes: a box body 210; a plurality of keychain receiving seats 220, the keychain receiving seats 220 are arranged in the box body 210 and fixed to a fixing rod 211 in the box body 210, and can releasably receive the keychain 100, the keychain receiving seat 220 has a keychain locking device 240, the keychain locking device 240 can move between a locking position (see Figure 10 ) and an open position (see Figure 11 ), wherein, in the locking position, the keychain 100 is locked into the keychain receiving seat 220, and in the open position, the keychain can be removed from the keychain receiving seat 220; and a control device 230, the control device 230 is arranged in the box body 210 and electrically connected to the keychain locking device 240 to control the keychain locking device 240 to move between the locking position (see Figure 10 ) and the open position (see Figure 11 ). The control device 230 is communicatively connected and electrically connected to the interface 170 of the keychain 100 through an interface 231 arranged in the keychain receiving seat 210.

[0089] As Figures 9 to 13 shown, the keychain management device 200 further includes a keychain ejection device 250 having a spring, the keychain ejection device 250 elastically presses the keychain 100 along the direction of ejecting the keychain 100 from the keychain receiving seat 220, so that when the keychain locking device 240 is in the open position of releasing the keychain 100 (see Figure 11 , Figure 13 and Figure 15 ), the keychain ejection device 250 can push the keychain 100 out of the keychain receiving seat 220.

[0090] The keychain management device 200 further includes a separately provided keychain position sensor (not shown), the keychain position sensor is used to at least detect whether the keychain 100 is located in the keychain receiving seat 220, and send a signal indicating whether the keychain 100 is located in the keychain receiving seat 220 to the control device 230. Alternatively or additionally, the control device 230 can also determine whether the keychain 100 is located in the keychain receiving seat 220 by detecting the position of the keychain ejection device 250, and / or, the control device 230 can determine whether the keychain 100 is located in the keychain receiving seat 220 by detecting the contact state between the interface 231 and the interface 170 of the keychain 100.

[0091] By using at least two different methods to determine whether the key fob 100 is located in the key fob receptacle 220, it is possible to more accurately determine whether the key fob 100 is located in the key fob receptacle 220, avoiding obtaining false detection results when one of the detection methods fails or encounters deception by unauthorized personnel. For example, an unauthorized person may push against the key fob ejection device 250 with sundries. If only the position of the key fob ejection device 250 is detected to determine whether the key fob 100 is located in the key fob receptacle 220, false detection results will be obtained, and the unauthorized person can use the key fob 100 without any restrictions. In contrast, if the position of the key fob ejection device 250 and the contact state between the detection interface 231 and the interface 170 of the key fob 100 are used as two detection methods to determine whether the key fob 100 is located in the key fob receptacle 220, it is easy to identify the above behavior of unauthorized personnel and obtain a more accurate judgment result.

[0092] As Figures 8 to 15 shown, the key fob locking device 240 includes a key fob locking device actuator 241 and a key fob locking device locking member formed by a pair of substantially L-shaped locking arms 242. The key fob locking device actuator 241 is a rotary actuator and cooperates with a pair of substantially L-shaped locking arms 242 through at least a part of its cam surface 243. It should be understood that the key fob locking device actuator 240 can also be a linear actuator.

[0093] The pair of substantially L-shaped locking arms 242 can be driven by the cam surface 243 of the key fob locking device actuator 241 to move between the locking position (see Figure 8 , Figure 10 , Figure 12 and Figure 14 ) and the open position (see Figure 11 , Figure 13 and Figure 15 ). Specifically, as Figures 10 to 15 shown, the first end 2421 of the pair of substantially L-shaped locking arms 242 cooperates with the cam surface 243 of the key fob locking device actuator 241 and is synchronously driven by the cam surface 243. The second ends 2422 of the pair of substantially L-shaped locking arms 242 are disposed on both sides of the housing 130 of the key fob 100 parallel to the direction in which the key fob ejects from the key fob receptacle. In the locking position of the key fob locking device locking member (see Figure 8 , Figure 10 , Figure 12 and Figure 14), the second ends 2422 of the pair of substantially L-shaped locking arms 242 enter the grooves (keychain locking device locking member matching portions) 180 on both sides of the housing 130 of the keychain 100 to lock the keychain 100 in the keychain receiving seat 220. In the open position of the keychain locking device locking member (see Figure 11 , Figure 13 and Figure 15 ), the second ends 2422 of the pair of substantially L-shaped locking arms 242 leave the groove 180 to allow the key fob ejection device 250 to release the key fob 100 from the key fob receiving seat 220.

[0094] like Figure 14 and 15 As shown, a pair of substantially L-shaped locking arms 242 of the keychain locking device 240 are further provided with elastic reset members 244. When the substantially L-shaped locking arms 242 are in the open position ( Figure 15 ), the elastic reset member 244 is compressed and moves toward the locking position ( Figure 14 ) pushes the first end 2421 of the substantially L-shaped locking arm 242.

[0095] As a possible implementation, the shape of the cam surface 243 is configured so that in the locking position ( Figure 14 ) and the open position ( Figure 15 ), the first ends 2421 of the pair of substantially L-shaped locking arms 242 do not exert any rotational torque on the cam surface 243. In this way, in both the locked position and the open position, the cam surface 243 is in a static position, so that no additional structure is required to maintain the keychain locking device 240 in the locked position and the open position. This not only simplifies the structure of the keychain locking device 240 but also improves the reliability of its locking and opening.

[0096] Although Figures 12 to 15 A pair of roughly L-shaped locking arms 242 are shown, but it should be understood that only an odd number (e.g., 1, 3, 5, etc.) of roughly L-shaped locking arms 242 may be provided, and more pairs (e.g., 2, 3, 4, etc.) of roughly L-shaped locking arms 242 may be provided.

[0097] The key fob management device 200 may further include a wired communication device and / or a wireless communication device (not shown) electrically connected to the control device 230 for receiving external signals, such as receiving instructions from a remote server, and may be used to send out signals, such as sending information indicating the status of the key fob management device 200, the key fob 100, etc. to the administrator of the key fob management device 200 or the remote server.

[0098] The key fob management device 200 may further include a fingerprint recognition device and / or a face recognition device and / or an image scanning device electrically connected to the control device 230 for collecting the identity information of the user operating the key fob management device 200 for operations such as appropriate authorization and authentication.

[0099] The key fob management device 200 may further include a visual indicator and / or an auditory indicator 260 electrically connected to the control device 230 to provide visual or auditory indications to the user. Additionally, the key fob management device 200 may further include a display screen 270 and a user input device (not shown, such as a keyboard, a mouse, a QR code scanner, an ID card reader, etc.) electrically connected to the control device 230. It should be understood that the display screen 270 may be a touch-sensitive display screen and thus serve as a user input device.

[0100] Similar to the key fob 100, the key fob management device 200 may further include a memory (not shown). In addition to storing the identity information for uniquely identifying the key fob management device 200, the memory may also store other information associated with the key fob management device 200. For example, the memory of the key fob management device 200 may store usage information of the key fob management device 200. The usage information may indicate, for example, whether the key fob management device 200 is for holding the keys of a rental house or the keys of a house for sale. Based on this usage information, different control rules, such as lending rules, return rules, etc., can be formulated for different key fob management devices 200. For another example, the memory of the key fob management device 200 may also store information related to the permitted usage time of the key fob management device 200, whereby it is possible to prevent the key fob from being lent out of the key fob management device 200 during non-usage times of the key fob management device 200. In addition, the memory may also store, for example: the address information of the key fob management device 200, such as the address information of the store where the key fob management device 200 is located; information about the key fob associated with the key fob management device 200; information related to the keys on the key fob associated with the key fob management device 200; information on whether there is a key fob 100 in each key fob receptacle 220 of the key fob management device 200, etc.

[0101] According to the present disclosure, a method for managing a keychain 100 is also provided, and the keychain 100 is stored in the keychain management device 200. As Figure 16 shown, the method includes: at step S100, receiving a user's key borrowing request, where the key borrowing request includes the user's identity information and the key information to be borrowed; at step S110, verifying the user's identity information; at step S120, in response to the verification of the user's identity information passing, determining the identity information of the target keychain management device where the target keychain is located according to the identity information of the target keychain where the key to be borrowed is located, and sending an instruction to eject the target keychain to the target keychain management device; and at step S130, in response to the verification of the user's identity information failing, sending a prompt and storing the user's identity information and the identity information of the target keychain. According to the present disclosure, the user's identity information includes one or more of the following: fingerprint information, facial image information, two-dimensional code information, and / or voice information.

[0102] In the above method according to the present disclosure, by verifying one or more biometric information including fingerprint information, facial image information, two-dimensional code information, and voice information, only authorized personnel can obtain the keychain 100 from the keychain management device 200. Additionally, when an unauthorized person attempts to obtain the keychain 100 from the keychain management device 200, the identity information of the unauthorized person and the information of the keychain they attempt to obtain can be recorded for retrieval when needed later.

[0103] It should be understood that at step S120, the user's identity information and the identity information of the target keychain can also be recorded to facilitate querying the identity information of the person using the target keychain.

[0104] Additionally, at step S120, after sending the keychain ejection instruction, the position information of the keychain is received and recorded to track the position information of the taken keychain. Further, step S120 may further include comparing the position information of the keychain with the target address information of the keychain, and in response to determining that the position information of the keychain deviates from the target address information, sending a warning message. Here, the target address information refers to the address information of the lock (or house) corresponding to the key carried by the target keychain.

[0105] Alternatively or additionally, step S120 may further include comparing the path information defined by multiple position information of the keychain with the target address information of the keychain, and in response to determining that the path information of the keychain deviates from the target address information, sending a warning message.

[0106] It should be understood that, according to the method of the present disclosure, in addition to detecting whether the lent key fob is properly used according to the target address information of the target key fob (such as the house address corresponding to the key carried by the target key fob), it is also possible to determine whether the lent key fob is properly used by monitoring the time when the key is lent. For example, if the travel time from the location of the key fob management device 200 to the target address information of the target key fob is 30 minutes and the normal house viewing time is 1 hour, then when it is monitored that the time when the key is lent has significantly exceeded the above normal travel time and house viewing time, it can be determined that the key fob is improperly used and a warning message is issued.

[0107] According to the present disclosure, the method further includes a key fob management device registration step, and the key fob management device registration step includes: receiving a key fob management device registration request, where the key fob management device registration request includes key fob management device identity information and key fob holder identity information associated with the key fob management device identity information; verifying the key fob management device identity information; and in response to the key fob management device identity information being verified, recording the key fob management device identity information and the key fob holder identity information associated with the key fob management device identity information.

[0108] According to the present disclosure, the method further includes a key fob registration step, and the key fob registration step includes: receiving a key fob registration request, where the key fob registration request includes key fob identity information; and / or detecting the key fob identity information of the key fob inserted into the key fob holder of the key fob management device; verifying the key fob identity information; and in response to the key fob identity information being verified, associating the key fob identity information with the key fob management device identity information and the key fob holder identity information of the key fob holder into which the key fob is inserted.

[0109] According to the present disclosure, the method further includes a key fob return step, and the key fob return step includes: detecting the key fob inserted into the key fob holder of the key fob management device; verifying the identity information of the inserted key fob; in response to the identity information of the key fob being verified, issuing an instruction to lock the key fob and associating the key fob identity information with the identity information of the key fob holder into which the key fob is inserted. In the key fob return step, in response to the key fob identity information not being verified, issuing an instruction to eject the inserted key fob through the key fob management device and / or issuing a warning message.

[0110] Alternatively, according to another embodiment of the present disclosure, the key fob return step may include: locking the key fob in response to the key fob being inserted into the key fob receptacle; verifying the identity information of the inserted key fob; and associating the identity information of the key fob with the identity information of the inserted key fob receptacle in response to successful verification of the identity information of the key fob. Additionally, in the key fob return step, in response to failure to verify the key fob identity information, an instruction to eject the inserted key fob through the key fob management device and / or a warning message is issued. In this embodiment, since the key fob is locked when it is detected to be inserted, this can ensure reliable communication connection and electrical connection between the interface in the key fob receptacle and the interface of the key fob to read the identity information of the key fob, then perform verification, and execute corresponding operations according to the verification result.

[0111] In the key fob return step, verifying the identity information of the inserted key fob includes verifying whether the identity information of the key fob is the identity information of a key fob associated with the key fob management device. In this way, it is possible to prevent inserting the wrong key fob into the key fob management device, which may cause the correct key fob to be unable to be inserted.

[0112] According to the present disclosure, the method further includes a key fob lending step, which includes: receiving a key fob lending request, the key fob lending request including the identity information of the lender and the identity information of the user associated with the target key fob to be lent; verifying the identity information of the user and the identity information of the lender; and associating the identity information of the lender with the target key fob in response to successful verification of the identity information of the user and the identity information of the lender. In this way, when multiple brokers successively borrow the same key fob, the information of the broker who is using the key fob can be accurately recorded, and it can prevent the broker from lending the key fob to an unauthorized broker.

[0113] Additionally, it is possible to limit the key fob lending step to be only performable at specific locations. For example, the key fob lending step may be allowed to be performed only at one or more of the following locations:

[0114] 1) At the key fob management device. Since the key fob management device is usually located inside the store, the key fob lending behavior can be appropriately monitored therefrom.

[0115] 2) At the house corresponding to the key carried by the key fob;

[0116] 3) Along the traffic route between the key fob management device and the house corresponding to the key carried by the key fob.

[0117] By defining the position of the keychain transfer step, the security of keychain lending can be significantly improved.

[0118] According to the present disclosure, the method further includes a key holder opening step, and the key holder opening step includes: receiving an opening request for opening the key holder, where the opening request includes the user's identity information and the identity information of the keychain corresponding to the key holder to be opened; verifying the user's identity information; and in response to the successful verification of the user's identity information, sending an instruction to open the key holder to the keychain corresponding to the identity information of the keychain according to the identity information of the keychain.

[0119] After the house corresponding to the key carried by the keychain is sold or rented, the key carried by the keychain needs to be replaced. In addition, during the process of selling or renting a house, it may also be necessary to add or replace the key carried by the keychain. Therefore, it is necessary to open the key holder of the keychain to operate the key carried by the key holder. According to the present disclosure, opening the key holder requires verifying the user's identity information, and only after the user's identity information is successfully verified, is the opening of the key holder allowed, thereby significantly improving the security of the keychain and preventing the keychain from being opened by unauthorized personnel, which may lead to the inability to monitor the use of the key carried by the keychain.

[0120] According to the present disclosure, there is also provided a keychain management system, and the keychain management system includes: a processor; and a memory storing a program, where the program includes instructions that, when executed by the processor of the electronic device, cause the electronic device to execute the above method. Additionally, the present disclosure also provides a computer-readable storage medium storing a program, where the program includes instructions that, when executed by the processor of the electronic device, cause the electronic device to execute the above method.

[0121] According to the present disclosure, the above keychain identity information, keychain management device identity information, and keychain holder identity information can be any information that can uniquely identify the keychain, keychain management device, and keychain holder, and the identity information can be non-tamperable identity information or identity information that is repeatedly modified and written into the keychain, keychain management device, and keychain holder.

[0122] Those skilled in the art should understand that the above-mentioned controller 150, control device 230, and electronic device can be any computing device configured to perform processing and / or calculations, and can be, but are not limited to, workstations, servers, desktop computers, laptop computers, tablet computers, personal digital assistants, smart phones, in-vehicle computers, or any combination thereof.

The output device can be any type of device capable of presenting information, and can include, but are not limited to, a display, a speaker, a video / audio output terminal, a vibrator, and / or a printer. The computing device may also include a non-transitory storage device or be connected to a non-transitory storage device. The non-transitory storage device can be any storage device that is non-transitory and can implement data storage, and can include, but are not limited to, a disk drive, an optical storage device, a solid-state memory, a floppy disk, a flexible disk, a hard disk, a magnetic tape, or any other magnetic medium, an optical disk, or any other optical medium, a ROM (read-only memory), a RAM (random access memory), a cache memory, and / or any other memory chip or cartridge, and / or any other medium from which a computer can read data, instructions, and / or code. The computing device may also include a communication device. The communication device can be any type of device or system that enables communication with external devices and / or with a network, and can include, but are not limited to, a modem, a network card, an infrared communication device, a wireless communication device, and / or a chipset, such as a Bluetooth™ device, a 1302.11 device, a WiFi device, a WiMax device, a cellular communication device, and / or the like.
