A lock, a two-dimensional code identification, and a password lock power supply module that uses a mobile phone to scan a two-dimensional code corresponding function to obtain a variable password

Abstract

The invention relates to a lock that uses a mobile phone to scan the corresponding function of a two-dimensional code to obtain a variable code, a two-dimensional code mark, and a combination lock power supply module, and belongs to the technical field of electronic information and shared locks. The present invention consists of 4 cipher disks, 4 cipher knobs, two-dimensional code signs, two-dimensional code built-in holes, elastic pressing keys, keyboard conductive rubber, etc.; each two-dimensional code corresponds to an independent function Fn, and this function exists As long as there is the same initial value in the memory of the variable password lock (8) and in the function library of the background management server, the same calculation result will be obtained. Scan and send the QR code with the mobile phone to obtain the input password for unlocking. The variable password function is realized; when the wrong password is entered more than three times in a row, a warning is issued; self-charging can be completed. Scan the QR code of the lock with the mobile phone to realize the function of the logistics network, which greatly reduces the cost of the lock and the development of the lock management program in the early stage, and only needs to develop the background management program.

Description

technical field [0001] The invention relates to a lock that uses a mobile phone to scan the corresponding function of a two-dimensional code to obtain a variable code, a two-dimensional code mark, and a combination lock power supply module, and 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...

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
