Dynamic password access control lock and operation method thereof

Abstract

The invention provides a dynamic password access control lock and an operation method thereof. The dynamic password access control lock comprises a main access control lock body, a power module, a communication circuit module and a control module, wherein the power module, the communication circuit module and the control module are all arranged in the main access control lock body; the communication circuit module and the control module are connected via a communication bus; the communication circuit module and the control module are both connected with the power module; the power module is used for supplying power to the communication circuit module and the control module; and the communication circuit module is used for the transmission and reception of working information or parametersbetween the control module and an operator. The dynamic password access control lock of the invention calculates and updates an unlocking password according to the real-time time and per time unit ofa key, and realizes remote unlocking and authority control management functions through the communication circuit module.

Description

technical field [0001] The invention belongs to the technical field of electronic access control locks, in particular to a dynamic password access control lock and an operation method. Background technique [0002] In daily industrial production and work, the security of industrial plants and departments, the storage of production materials, financial statements and some important personal data are mostly solved by locking. Traditional locks mainly use tumbler locks, whose keys are easy to lose and through years of use and research, people understand its mechanism and structure quite clearly, and there are countless ways to open locks without using keys. Traditional mechanical locks with simple structures, even ordinary people, can easily open most of the seemingly safe mechanical locks after a short period of lockpicking practice. For these reasons, traditional mechanical locks have gradually lost their role in protecting industrial production materials. [0003] Improving...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned functions of these industrial access control locks all have their own deficiencies.

The password set by the "arbitrary password setting" technology is too single. Once set, it must be used for a long time, which is easy to cause human leakage; industrial electronic locks with fingerprint recognition and iris recognition, due to the large number of people who need authorization in the industrial environment, each For new personnel authorization, personnel information must be entered on-site. The operation process is cumbersome, the repetitive process is large, and it takes too much time. It is easy to be deceived by the molded silicone and photos to unlock the lock; and industrial sites generally do not have Internet wifi. Remotely unlocked electronic locks can only be used in an environment like a personal home with wifi, and cannot be used in an industrial production environment
