DETAILED DESCRIPTION

[0028] In order to further understand the structure, features and other purposes of the present invention, the preferred embodiments are described in detail with reference to the accompanying drawings as follows. The embodiments described in the drawings are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention.

[0029] In the first embodiment of the present invention, the present invention provides a passive electronic lock key management system, including a control unit 1, a user identification unit 2, an unlocking and locking control unit 3, a key identification unit 4, a key charging unit 5, a data synchronization unit 6, a communication unit 7 and a server 8.

[0030] like Figure 1 As shown, the user identification unit 2 is electrically connected and signal-connected with the control unit 1. The user identification unit 2 identifies user information and determines user authority, and sends a first signal to the control unit 1. The unlocking and locking control unit 3 is electrically connected and signal-connected with the control unit 1 and the smart key 9, respectively. The unlocking and locking control unit 3 controls the corresponding smart key 9 to unlock according to the first signal of the control unit 1. After the user identity is identified by the user identification unit 2, the smart key 9 is controlled to unlock, realizing the user identity identification function, and the user's borrowed keys can be recorded to facilitate key management.

[0031] like Figure 1 As shown, the key recognition unit 4 is electrically and signally connected to the control unit 1 and the smart key 9, respectively. The key recognition unit 4 recognizes whether the smart key 9 is in place, and sends a second signal to the control unit 1. Then, the unlocking and locking control unit 3 controls the corresponding smart key 9 to be locked according to the second signal of the control unit 1, and sends a third signal to the control unit 1. After the key recognition unit 4 recognizes that the smart key 9 is in place, the unlocking and locking control unit 3 automatically locks the smart key 9, which is convenient for the user to return the key.

[0032] like Figure 1 As shown, the key charging unit 5 is electrically and signal-connected with the control unit 1 and the smart key 9, respectively. The key charging unit 5 charges the smart key 9 according to the third signal control of the control unit 1. After the user returns the key and the unlocking and locking control unit 3 automatically locks the smart key 9, the key charging unit 5 can automatically charge the smart key 9.

[0033] like Figure 1 As shown, the data synchronization unit 6 is electrically connected and signal-connected with the control unit 1, and the data synchronization unit 6 is controlled by the control unit 1. The data synchronization unit 6 is electrically connected and signal-connected with the smart key 9 and the communication unit 7, respectively, and the communication unit 7 is wirelessly connected with the server 8. The data synchronization unit 6 starts to read the operation record data and power data of the smart key 9 according to the third signal of the control unit 1, and uploads it to the server 8 by the communication unit 7, so as to realize data synchronization between the smart key 9 and the server 8, and facilitate key management.

[0034] In the second embodiment of the present invention, the user identification unit 2 includes a user identification module 21 , a user authority determination module 22 , an indicator light module 23 , a timing module 24 and an alarm module 25 .

[0035] like Figure 2 As shown, the user identification module 21 is electrically and signally connected to the control unit 1 and the user authority judgment module 22 respectively. The user identification module 21 is used to identify user information and transmit the user information to the user authority judgment module 22 to realize the identity recognition of the user information. Preferably, the user identification module 21 is one or more of keyboard input number and password recognition, fingerprint recognition, and IC / ID card reader recognition. By setting a keyboard and an OLED screen, the user enters the user number and password to realize user authority judgment; by setting a fingerprint module, the user can confirm the identity through fingerprints; by setting an IC / ID card reader, the user can confirm the identity by swiping a work card.

[0036] like Figure 2 As shown, the user authority judgment module 22 is electrically and signal-connected with the communication unit 7. The user authority judgment module 22 uploads the received user information from the communication unit 7 to the server 8 for verification, and the server 8 sends the verification result to the user authority judgment module 22. The user authority judgment module 22 generates an authorized user signal when the verification is successful, and generates a non-authorized user signal when the verification fails.

[0037] like Figure 2 As shown, the indicator light module 23, the timing module 24 and the control unit 1 are electrically connected and signal connected to the user authority judgment module 22 respectively. The indicator light module 23 controls the indicator light of the corresponding smart key 9 to light up according to the authorized user signal of the user authority judgment module 22 to prompt the user to take out the key. At this time, the control unit 1 has controlled the unlocking and locking control unit 3 to unlock the corresponding smart key 9 according to the authorized user signal of the user authority judgment module 22. The timing module 24 starts timing according to the authorized user signal of the user authority judgment module 22, and sends a fourth signal to the control unit 1 after the preset time ends. At this time, the control unit 1 controls the unlocking and locking control unit 3 to lock the corresponding smart key 9 according to the fourth signal of the timing module 24. If the user does not take out the key within the preset time, the unlocking and locking control unit 3 automatically locks the smart key 9.

[0038] like Figure 2 As shown, the alarm module 25 is electrically and signal-connected to the user authority judgment module 22. The alarm module 25 issues an alarm prompt according to the unauthorized user signal of the user authority judgment module 22. The alarm module 25 issues an alarm prompt for the operation of the unauthorized user to prevent unauthorized persons from obtaining the key, thereby ensuring the safe use of the key.

[0039] In this embodiment, the user identity information is obtained through the user identification module 21, and the user authority judgment module 22 generates an authorized user signal when the verification is successful. The control unit 1 controls the unlocking and locking control unit 3 to unlock the corresponding smart key 9 according to the authorized user signal of the user authority judgment module 22. At the same time, the indicator light module 23 controls the indicator light of the corresponding smart key 9 to light up to prompt the user to take out the key. The timing module 24 starts the timing. If the user does not take out the key within the preset time, the unlocking and locking control unit 3 automatically locks the smart key 9. The user authority judgment module 22 generates an unauthorized user signal when the verification fails, and the alarm module 25 alarms the operation of the unauthorized user to prevent unauthorized personnel from obtaining the key, so as to ensure the safe use of the key.

[0040] like Figure 5 As shown, it is a flowchart of a user lending a key. A key management seat that can provide four smart key card holders is used, and the smart key 9 is placed in the smart key card holder and locked by the unlocking and locking control unit 3. The user identification module 21 can provide identification methods such as swiping a card, entering a user name and password, or entering a fingerprint, and the user can choose any of them to enter user information. Then the user authority judgment module 22 judges the user authority based on the user information. When the user is judged to be an illegal user (i.e., an unauthorized user), the alarm module 25 will alarm to end the lending process. When the user is judged to be an authorized user, the unlocking and locking control unit 3 controls the opening of the card holder from which the key can be taken out, and the indicator light module 23 controls the corresponding indicator light to light up, waiting for the user to take out the key. At this time, the timing module 24 starts timing, and sends a fourth signal to the control unit 1 when the preset time is exceeded, and the unlocking and locking control unit 3 controls the card holder from which the key has not been taken out to lock, and the lending process ends. If the user directly takes out the key, he can choose to press any key to exit, and then the unlocking and locking control unit 3 controls the card holder at that place to lock, and the lending process ends.

[0041] like Figure 6 The figure shows a flowchart of a user returning a key. The key is inserted into an empty card holder. At this time, the key identification unit 4 determines whether the smart key 9 is correct and placed in place. When the smart key 9 is correct and placed in place, the unlocking and locking control unit 3 controls the corresponding card holder to lock the smart key 9. Then, the data synchronization unit 6 starts to read the key record and synchronize the key data to the server 8 to end the return process. After the return process is completed, the key charging unit 5 can automatically charge the returned key.

[0042] In the third embodiment of the present invention, the key charging unit 5 includes a charging control module 51 , a power detection module 52 and a power supply module 53 .

[0043] like Figure 3As shown, the charging control module 51 is electrically connected and signal-connected with the control unit 1 and the power detection module 52, respectively, and the power detection module 52 is electrically connected and signal-connected with the smart key 9. The charging control module 51 controls the power detection module 52 to detect the power of the smart key 9 according to the third signal of the control unit 1, and the power detection module 52 detects the remaining power of the smart key 9 and sends it to the charging control module 51. Preferably, the power detection module 52 detects the remaining power of the smart key 9 using a voltage reference device and a power management chip in the prior art.

[0044] like Figure 3 As shown, the charging control module 51 is electrically and signal-connected with the power supply module 53, and the power supply module 53 is electrically and signal-connected with the smart key 9. The charging control module 51 controls the power supply module 53 to charge or stop charging the smart key 9 according to the remaining power of the smart key 9.

[0045] In this embodiment, after the key is returned and the unlocking and locking control unit 3 controls the corresponding smart key 9 to be locked, the unlocking and locking control unit 3 sends a third signal to the control unit 1, and then the control unit 1 controls the charging control module 51 to work. The charging control module 51 controls the power detection module 52 to monitor the remaining power of the smart key 9, and controls the power supply module 53 to charge or stop charging the smart key 9 to ensure that the power of the smart key 9 is sufficient and the service life of the battery in the smart key 9. For example, when the power detection module 52 detects that the remaining power of the smart key 9 is less than 80%, the charging control module 51 controls the power supply module 53 to charge the smart key 9, and when the power detection module 52 detects that the remaining power of the smart key 9 is higher than 90%, the charging control module 51 controls the power supply module 53 to stop charging the smart key 9. The control unit 1 sends the lower limit value for starting charging and the upper limit value for stopping charging to the charging control module 51.

[0046] In the fourth embodiment of the present invention, preferably, the data synchronization unit 6 includes a data line connected to the smart key 9 through the key identification unit 4, so that when the smart key 9 is placed in place in the key identification unit 4, the data synchronization unit 6 is connected to the smart key 9. After the unlocking and locking control unit 3 controls the corresponding smart key 9 to lock, the control unit 1 controls the data synchronization unit 6 to transmit the operation record data and power data of the smart key 9 to the communication unit 7 through the data line, and the communication unit 7 uploads it to the server 8, so as to realize the data synchronization between the smart key 9 and the server 8, obtain the usage information of the smart key 9 in time, and facilitate the management of the key. For example, the user can modify the password and fingerprint on the smart key 9, and after the smart key 9 is returned and put back into the lock, the modified data can be transmitted back to the server.

[0047] In a fifth embodiment of the present invention, Figure 4 As shown, the communication unit 7 is electrically connected and signal-connected with the storage unit 10. The communication unit 7 is used to receive tasks, user data, and update data issued by the server 8 and transmit them to the storage unit 10 for storage. The storage unit 10 is electrically connected and signal-connected with the control unit 1 and the data synchronization unit 6, respectively. When the control unit 1 receives the third signal, the control unit 1 controls the storage unit 10 to synchronize the tasks, user data, and update data issued by the server 8 to the corresponding smart key 9 through the data synchronization unit 6. For example, when a user modifies the password and fingerprint on a smart key 9, after the smart key 9 is returned to a certain place and put back in the lock, the modified data can be transmitted back to the server. After the smart key 9 is used again and returned to another place, the server can also synchronize the modified information to the storage unit 10 at the current location.

[0048] In this embodiment, the tasks, user data, and update data sent by the server 8 can be first transmitted to the storage unit 10 for storage. After the unlocking and locking control unit 3 controls a certain smart key 9 to lock, the control unit 1 controls the data synchronization unit 6 to synchronize the tasks, user data, and update data corresponding to the smart key 9 in the storage unit 10 to the smart key 9, ensuring that the borrowed smart key 9 can synchronize the tasks, user data, and update data sent by the server 8 in a timely manner after being returned. Data synchronization is achieved by receiving the tasks and user data sent by the server; and automatic key upgrades are achieved by receiving software updates sent by the server.

[0049] In the sixth embodiment of the present invention, preferably, the unlocking and locking control unit 3 is an electromagnetic controller for unlocking or locking the smart key 9. The smart key 9 is unlocked or locked by the electromagnetic controller, which ensures the safety of unlocking or locking the smart key 9 and the convenience of use.

[0050] In the seventh embodiment of the present invention, preferably, the key identification unit 4 is provided with a contact for magnetically attracting the smart key 9, so that the smart key 9 is magnetically connected to the contact when the key identification unit 4 is placed in place. The contact magnetic connection realizes automatic alignment for fast charging and data transmission when the key identification unit 4 is placed in place, thereby increasing the reliability of communication.
