The present disclosure relates to a combination lock system, and more particularly to a combination lock system applied to a cloud authentication and having a function of displaying whether a password is correct.
In modern life, as people's awareness of privacy and personal property rises, a combination lock is a common security tool. In the past, when you used a key to open a home door lock or a locker that is locked, it was easy to pry open and steal contents. Therefore, in order to prevent criminals, the user only needs to set the password of the combination lock according to his or her favorite number, and then the user can lock the combination lock by turning a plurality of character wheels or pressing a plurality of keys. When a password by turning the plurality of character wheels or pressing the plurality of keys matches the password set by own, the combination lock can be unlocked.
However, all the characters of the password are matched to unlock the lock. If the user cannot successfully unlock the combination lock due to forgetting the password set by own, there is no other secure and non-intrusive method (including inserting a physical key or destroying the entire combination lock) to unlock the combination lock.
For this reason, how to design a combination lock system, in particular to solve the technical problem about in prior art there is no other secure and non-intrusive method to unlock the combination lock when the password set by own is forgotten, and the technical problem about no unlocking record when unlock the combination lock. This is an important subject studied by the inventor of this present disclosure.

In order to achieve the foregoing purpose, a combination lock system of the present disclosure includes a mobile communication device, a cloud server, and a combination lock. The mobile communication device stores a first authentication information and outputs a first near field communication (NFC) signal. The cloud server stores a second authentication information and a plurality of password information, and receives the first authentication information. When the cloud server determines that the first authentication information matches the second authentication information, the cloud server outputs one of the plurality of the password information corresponding to the first authentication information to the mobile communication device. The combination lock includes a password setting module that adjustable, and the combination lock obtains an electric energy and the password information from the mobile communication device through the first NFC signal. When the combination lock determines that one of characters of the password setting module matches one of characters of the password information in a corresponding arrangement order, the combination lock outputs a display information to the mobile communication device through a second NFC signal, and the mobile communication device displays the display information. When the combination lock determines that one of the characters of the password setting module does not match one of the characters of the password information in the corresponding arrangement order, the combination lock continues to determine whether one of the characters of the password setting module matches one of the characters of the password information in the corresponding arrangement order. After the combination lock obtains the password information from the mobile communication device through the first NFC signal, regardless of the combination lock determines whether the password setting module matches the password information, the combination lock outputs a combination lock record to the mobile communication device through the second NFC signal.
Further, in the combination lock system, the password setting module includes one of a plurality of letter wheels, a plurality of numeral wheels, and a plurality of buttons, or combinations thereof.
Further, in the combination lock system, the combination lock further comprising a microcontroller, a general-purpose input/output (GPIO) unit and an antenna, the microcontroller coupled to the password setting module through the GPIO unit, and obtained the power and the password information from the mobile communication device though the antenna.
Further, in the combination lock system, if the mobile communication device can wirelessly communicate with the cloud server after receiving the combination lock record, the mobile communication device outputs the combination lock record to the cloud server.
Further, in the combination lock system, if the mobile communication device cannot wirelessly communicate with the cloud server after receiving the combination lock record, the mobile communication device temporarily stores the combination lock record in a storage module within the mobile communication device until the mobile communication device determines that a wireless communication with the cloud server is possible, and then the mobile communication device outputs the combination lock record stored in the storage module to the cloud server.
Further, in the combination lock system, the combination lock record includes a time stamp, the password information, and a unique identifier corresponding to the mobile communication device.
When using the combination lock system of the present disclosure, since the mobile communication device must authenticate with the cloud server according to the first authentication information outputted, and if the first authentication information and the combination lock are matched and can be sold together, so it can ensure that it is difficult for someone to try to imitate other first authentication information or other combination locks to achieve a purpose of unlocking the combination lock. Further, when user forgets the password set by own and cannot unlock the combination lock successfully, the combination lock can be unlocked non-intrusively by the password information obtained after the mobile communication device is authenticated and the password setting module of the combination lock. If one of the characters of the password setting module of the combination lock module matches one of the characters of the password information in the corresponding arrangement order, the combination lock outputs the display information to the mobile communication device, and the mobile communication device displays the display information. In addition, regardless of whether the combination lock is successfully unlocked (regardless of whether the password setting module matches the password information), the combination lock record and outputs the combination lock record to the mobile communication device. In case of malicious trial and error or malicious unlock by someone, it can be tracked by the combination lock record.
For this reason, the combination lock system that solves the technical problem about in prior art there is no other secure and non-intrusive method to unlock the combination lock when the password set by own is forgotten, and regardless of whether the combination lock is successfully unlocked, there has a record to achieve a purpose of convenience and enhance the safety of the combination lock.
