Variable two-dimensional code lock

Abstract

A variable two-dimensional code lock is based on a smallest single chip microcomputer system and comprises a variable two-dimensional code display module, a two-dimensional code internal-processing module, a keyboard password inputting submodule, a power supply circuit, a reset oscillating circuit, an unlocking circuit, a two-dimensional code switch, a lock state detecting module, an internal timing module and a server matched with the variable two-dimensional code lock in use. The lock state detecting module belongs to a subprogram in an internal master control program of a single chip microcomputer, whether the variable two-dimensional code lock is in an unlocked or locked mode is judged by detecting a high-level or low-level signal sent by the single chip microcomputer to an I / O port connected with the keyboard password inputting submodule, the two-dimensional code switch sends a switching signal to the single chip microcomputer after being pressed, the single chip microcomputer re-generates a two-dimensional code when the signal produced by the two-dimensional code switch is received each time, the two-dimensional code is scanned by using a user client-side and is sent to the server, the server analyzes the two-dimensional code and then obtains and sends the two-dimensional code to the client-side, and a user reads a password to achieve unlocking.

Description

technical field [0001] The invention relates to a variable two-dimensional code lock, which belongs to the technical field of electronic information and shared locks. Background technique [0002] The bicycle locks used by OFO shared bicycles do not directly enter the Internet of Things, but realize the interaction with the network through the people who use the shared bicycles when they scan. This method can greatly reduce the initial research and development costs and the production costs of bicycle locks. , which is a very valuable business model for companies that have just entered the sharing platform, which can greatly reduce R&D costs and facilitate promotion. However, there is a serious problem in this mode that the password of the OFO lock cannot be changed. For bicycles, since the parking position of the bicycle is not fixed, this greatly alleviates the disadvantages of the OFO lock. Even so, many people who want to take advantage of it are still happy to unlock t...

AI Technical Summary

Problems solved by technology

Judging from the current situation, we are faced with a dilemma. If the password remains unchanged, the provided shared equipment will be occupied free of charge; if the password is not used, but Internet management is used, it means that the initial development cost is too high
