Electronic cipherer

Abstract

The invention discloses an electronic cipherer in the field of coded locks. The electronic cipherer comprises a data processing and controlling module, a keyboard input module, a code storage module, a display module and a buzzer alarming module. An output end of the keyboard input module is in connection with an input end of the data processing and controlling module. An output end of the data processing and controlling module is in connection with the display module. The data processing and controlling module is further in connection with the code storage module and the buzzer alarming module. Due to a circuit structure, a function of a lock is achieved, a user does not need to carry a key needed by a mechanical lock, and therefore convenience is achieved, beside, safety and reliability performance of the electronic cipherer is high, and the electronic cipherer is applicable to various gate locks.

Description

technical field [0001] The invention relates to a combination lock, in particular to an electronic combination lock. Background technique [0002] At present, mechanical lock is one of the most commonly used locks in people's daily life, and its mechanism is simple, easy to use, and cheap. However, many shortcomings have been exposed in use: First, the mechanical lock works by the cooperation of different tooth shapes on the metal key and the lock cylinder. According to statistics, there are two key teeth in every 4000 locks. The teeth are the same or similar, so the security is low; the second is that once the key is lost, no matter who finds it, the lock can be opened; the third is that the material of the mechanical lock is soft and easy to damage. The 4th, mechanical lock key is easy to duplicate, is not suitable for public places such as hotels to use. Contents of the invention [0003] The object of the present invention is to provide an electronic coded lock, whic...
