Electronic lock

Abstract

The invention relates to a lockset, in particular to an electronic lock. The electronic lock has a simple structure and good security and needs no continuous power supply. The electronic lock comprises a main controller, a password digit setting circuit, a preset number circuit, a numeric keyboard, a trap setting circuit and an executing mechanism, and is characterized in that the main controller, of which a plurality of output ends are high (or low) level digital integrated circuits or the circuits with same functions after combination when each message is input, is used, and the output end of the main controller is connected in series with multi-position switches to perform password setting and password capacity expansion. The multi-position switches are connected in series with corresponding number keys of a multi-position numeric keyboard.

Description

Technical field: [0001] The invention relates to a lock, in particular to an electronic lock. Background technique: [0002] Locks have always been closely related to people's lives and property safety. The existing locks can be roughly divided into two categories, one is mechanical locks, and the other is electronic locks; due to the continuous development and improvement of science and technology, the structure of locks is also constantly improving, and has gradually evolved from mechanical locks to electronic locks. Locks, mechanical locks are simple in structure and cheap in price, but have the following problems: as long as there is an imitation key, it is easy to open it, and the security performance is not good; the electronic lock is a new type of lock, and its security is good. With the rapid development of electronic technology, there are more and more types of electronic locks, and their performance is becoming more and more perfect. High-end electronic locks wi...

Problems solved by technology

The existing locks can be roughly divided into two categories, one is mechanical locks, and the other is electronic locks; due to the continuous development and improvement of science and technology, the structure of locks is also constantly improving, and has gradually evolved from mechanical locks to electronic locks. Locks, mechanical locks are simple in structure and cheap, but there are the following problems: as long as there is an imitation key, it is easy to open it, and the security performance is not good; the electronic lock is a new type of lock, and its security is good.

High-end electronic locks with relatively comprehensive functions mostly use single-chip microcomputers, programmable logic circuits, and special cryptographic circuit technologies. The circuits are more complicated and the price is more expensive.

Due to many reasons such as technology, price, power supply and use, some small locks such as car steering wheel locks, motorcycle locks, etc., cannot use electronic locks, only mechanical locks can be used, and most home security doors use mechanical locks. life has brought many safety hazards
