Abstract
Description
Technical Field
[0001] This utility model relates to the field of key cabinet technology, specifically to an intelligent key cabinet with layered and hierarchical automatic key borrowing and returning. Background Technology
[0002] Large hydropower stations contain numerous pieces of equipment located in various locations. To protect equipment safety, some equipment rooms can only be opened with keys, without card access control. Furthermore, due to the varying importance of different equipment, key management authority differs. Currently, maintenance personnel frequently need to borrow keys from the control building's ticket office. When borrowing keys, the shift operator not only needs to check the paper work order and staff identification but also verify that the work location on the work order matches the key borrowing location before lending the key to the maintenance staff. During shift handover, the number of keys needs to be counted individually. Due to the large number of keys, manual counting makes it difficult to ensure accurate key handover. During annual maintenance, the shift operator has a heavy workload processing work orders and performing operations, while also conducting equipment inspections, making it difficult to manage key borrowing effectively. Utility Model Content
[0003] The purpose of this invention is to provide a smart key cabinet with hierarchical automatic key borrowing and returning, which solves the technical problems of low efficiency and high error rate in the existing key management system, which mainly relies on manual labor.
[0004] This utility model discloses a smart key cabinet with hierarchical automatic key borrowing and returning, including a controller. The controller is connected to an identity verification module and an access control module. The access control module includes at least two levels of access control. The controller is also connected to key boxes corresponding to the access control levels.
[0005] Working principle: When in use, after the staff are confirmed by the identity verification module and the permission verification module, the controller automatically opens the key box with the corresponding permission to facilitate the use of the key, which solves the technical problem that key management in the existing technology mainly relies on manual labor, resulting in low efficiency and high error rate.
[0006] Furthermore, the identity verification module uses contactless radio frequency identification, QR code recognition, or facial recognition.
[0007] By setting up multiple identity verification modules, it is easy to identify individuals in an appropriate manner depending on the situation.
[0008] Furthermore, the identity verification module also includes electronic signature.
[0009] Furthermore, each key in the key box is equipped with a corresponding contact sensor.
[0010] By equipping each key with a contact sensor, precise management of each key can be achieved, preventing accidental key removal.
[0011] Furthermore, the contact-type sensing device is connected to an indicator light.
[0012] By setting indicator lights, the borrowing status of keys can be clearly seen, making it easier for managers to issue key permissions.
[0013] Furthermore, the contact sensor is connected to an alarm.
[0014] The alarm system can alert staff when the wrong key is taken, thus preventing such errors from occurring.
[0015] Furthermore, each key in the key box is equipped with a corresponding electronic access lock.
[0016] By setting up electronic access control locks, the locker door of the corresponding key box will open and the electronic access control lock of the corresponding key will open after both the identity verification module and the authorization verification module have confirmed the key, so that the key can be retrieved and other keys cannot be taken.
[0017] Furthermore, the controller exchanges information with the EP office software.
[0018] By exchanging information with EP office software, identity and permission information can be set through EP office software, making it more efficient to use.
[0019] Furthermore, the permission confirmation module includes three levels of permissions: a first-level permission key, a second-level permission key, and a third-level permission key.
[0020] By setting up three levels of permissions, the key cabinet can be managed hierarchically, making it easier to retrieve and return keys.
[0021] Furthermore, the key box consists of three parts: a general key box, an important key box, and a core key box.
[0022] By setting up three key boxes, corresponding to the levels of the access control module, it is easy to manage keys of different importance separately.
[0023] Compared with the prior art, the beneficial effects of this utility model are:
[0024] 1. After the identity verification module and the permission verification module confirm the key, the controller automatically opens the key box with the corresponding permission to facilitate the use of the key, which solves the technical problem that key management in the existing technology mainly relies on manual labor, resulting in low efficiency and high error rate;
[0025] 2. By setting up three levels of permissions, the key cabinet can be managed hierarchically, making it easier to retrieve and return keys;
[0026] 3. By setting up three key boxes, corresponding to the levels of the access control module, it is convenient to manage keys of different importance separately;
[0027] 4. By setting up multiple identity verification modules, it is convenient to identify identities in an appropriate manner according to the situation;
[0028] 5. By equipping each key with a contact sensor, precise management of each key can be achieved, preventing accidental key removal;
[0029] 6. The indicator lights clearly show the key borrowing status, making it easier for managers to issue key permissions.
[0030] 7. An alarm system can be activated to alert staff if the wrong key is taken, thus preventing the accidental takeover of keys.
[0031] 8. By setting up electronic access control locks, the locker door of the corresponding key box will open and the electronic access control lock of the corresponding key will open after both the identity verification module and the authorization verification module have confirmed the key, so that the key can be retrieved and other keys can be prevented from being taken.
[0032] 9. By exchanging information with EP office software, identity and permission information can be set through EP office software, making it more efficient to use. Attached Figure Description
