Dynamic code lock system and unlocking method

Abstract

The invention relates to a dynamic code lock system. The dynamic code lock system comprises a lock, a mobile terminal and a cloud server, wherein the mobile terminal is in communication connection with the cloud server; the mobile terminal is in interactive connection with the lock via a dynamic identification code; the lock comprises a lock body, a main controller and a display device, an input module, an encrypting module and an identification code generation module which are connected with the main controller; the identification code generation module is connected with the encrypting module; a decrypting module is arranged in the cloud server and is matched with the encrypting module. An unlocking method of the dynamic code lock system comprises the following steps of generating a random identification code, encrypting the identification code to obtain a code, enabling the code to generate the identification code through the identification code generation module, enabling the mobile terminal to obtain the identification code and upload to the cloud server, enabling the decrypting module to decrypt the code and send to the mobile terminal, and unlocking the lock according to the identification code. The dynamic code lock system has the advantages that under the condition of no communication between the lock and the cloud server, the lock can be unlocked; the operation cost is reduced.

Description

technical field [0001] The invention relates to a dynamic combination lock system, and also relates to an unlocking method of the dynamic combination lock system. Background technique [0002] With the rapid development of science and technology and the continuous improvement of security requirements, electronic unlocking devices and unlocking methods using dynamic passwords are emerging in an endless stream. For example, the authorized announcement number is CN205680158U (application number is 201620609238.9) Chinese utility model patent "Dynamic Hermetic Lock Based on the Internet of Things", wherein the disclosed dynamic combination lock includes combination lock body module, mobile terminal, background monitoring module and encryption module, password The data transmission connection between the lock body module and the background supervision module, the data transmission connection between the mobile terminal and the background supervision module, the data transmission ...

AI Technical Summary

Problems solved by technology

In this solution, the combination lock body module needs to communicate with the background supervision module during the unlocking process. In this way, the combination lock needs to have a built-in communication module, so the structure of the lock body is complicated, the reliability is not high, and the cost is high.

At the same time, the combination lock needs to be online in real time, and the occasional disconnection will affect the normal unlocking of the combination lock. In addition, the real-time online also needs to pay high communication fees to the communication company, and the operating cost is high.
