Technical Field

The present invention relates to the field of intelligent Internet of Things locks/keys, and in particular to an intelligent Internet of Things lock/key system and a control method thereof.

Background Art

With the development of society and the improvement of customer-centric product concepts, banks, power, government and other fields have deployed more and more smart self-service terminals in their jurisdictions in order to improve the efficiency and service capabilities of their business handling, reduce labor input, and improve the ability to arrange and guarantee. The increasing use of smart self-service terminals and the increasing number of them year by year have brought a series of problems to the management of lock keys on smart self-service terminals: how to ensure convenience, security, process controllability and traceability. Taking bank equipment as an example, there are often more than ten or even more mechanical locks used on a comprehensive smart self-service terminal. Each mechanical lock needs to be equipped with a separate key, which brings great inconvenience to the equipment administrator in key management and use. At the same time, mechanical locks cannot avoid the problem of mutual opening rate, and anyone with the key can open the corresponding lock. The security control of keys and locks and the record of their use also depend entirely on the administrator's operation and management level.

For example, a "fingerprint-authenticated smart active electronic key and passive smart lock and implementation method thereof" disclosed in Chinese patent literature, with publication number: CN106296897A, discloses an electronic key and a passive smart lock with a built-in power supply, realizing a smart key that provides unlocking and power through a key, but the power supply security is not high, the passive design is unreasonable, and the confidentiality function cannot be achieved when the decrypted information is leaked.

S4. The intelligent interconnected lock determines whether it is an illegal intrusion according to the power-on status; compares the power-on mode with the power supply mode of the encryption mode called from the database in advance. If they are consistent, the correct information is sent to the locking mechanism. The locking mechanism determines whether it is an illegal intrusion according to the decoded information obtained from the power receiving module and the first decryption module at the same time.

After judging that it is an illegal intrusion, the locking module is locked and the smart IoT lock sends an alarm message to the IoT management platform and then is forced to lose power, that is, no more electrical interaction is performed to protect the safety of the smart IoT lock. After judging that it is unlocked correctly, the locking mechanism in the locking module receives power and unlocks.
