Intelligent multi-angle knock-on type algorithm coded lock

Abstract

The invention discloses an intelligent multi-angle knock-on type algorithm coded lock and relates to the field of the coded locks. The intelligent multi-angle knock-on type algorithm coded lock comprises a coded lock part and an intelligent control system for opening and closing the coded lock part in a three-axis six-face knock-on mode. The intelligent control system comprises a power supply part for supplying power to the whole system, a MCU processor used as a control operation core, a data storage module, a motor driving circuit, a prompt part and a sensor module. The MCU processor adopts a MCU control chip. The output end of the motor driving circuit controls a motor for opening and closing the coded lock. The MCU processor outputs a control signal to the motor driving circuit. Opening of the coded lock is achieved in a three-axis six-face knock-on mode, no key is needed completely, the code combination number is greatly increased, the false accept rate (misoperation prevention) is low, the true rejection rate is low, the knock-on characteristics of hands can be more easily recognized through the optimization sensor algorithm, the true accept and false rejection rate ability is further improved, and easy accept and stability are achieved.

Description

technical field [0001] The invention relates to a combination lock, in particular to an intelligent multi-angle knocking algorithm combination lock. Background technique [0002] Combination lock is a kind of lock, which is opened with a series of numbers or symbols. Text combination lock can be divided into: mechanical combination lock, digital combination lock and so on. The codes of combination locks are usually just permutations rather than real combinations. Some combination locks only use a turntable to turn several discs or cams inside the lock; some combination locks turn a set of dials engraved with numbers to directly drive the mechanism inside the lock. [0003] At present, the locks on the market are generally opened with fingerprints, keys, and door cards. If you forget to bring the key or door card, you will not be able to open it. Many combination locks use six-digit long and short code combinations, and the number of combinations is: 26 = 64 One, very easy ...
