Frequency electromagnetic lockset

Abstract

The invention discloses a frequency electromagnetic lockset comprising a key contact and a matched encryption lock end. The key contact includes a stepped segment selection crystal array, selected insertion electrodes, a segmented frequency output head, a segment code signal synthesizer and a lap joint contact. The matched encryption lock end includes a segment code signal frequency-to-voltage converter, an electromagnetic driving source selector and an elastic code switch. The selected insertion electrodes are inserted into different position segments of the stepped segment selection crystalarray; the segment frequency output head is connected to the selected insertion electrodes by a segmented joint; and a signal output terminal of the segmented frequency output head is connected to thesegment code signal synthesizer. The key contact is connected to a power output terminal and a signal input terminal of the matched encryption lock end through a lap joint; a signal input terminal isconnected to the segment code signal frequency-to-voltage converter; the segment code signal frequency-to-voltage converter is connected to the electromagnetic driving source selector; the electromagnetic driving source selector is connected to the elastic code switch by an electromagnetic head. The frequency electromagnetic lockset has advantages of high safety and low energy consumption; and repeatability of a mechanical lock and insecurity of the electronic access control lock are overcome.

Description

technical field [0001] The invention relates to an intelligent electronic lock device, in particular to a frequency electromagnetic lockset. Background technique [0002] The traditional mechanical lock mainly realizes the one-to-one matching between different keys and the lock through the metal tooth pattern of the key. However, due to the mechanical error and the coincidence probability of this kind of tooth pattern, it is easy for the key tooth pattern to overlap. And this kind of mechanical key is not safe and is easy to be imitated. [0003] However, some electronic access control systems and electronic lock systems need to use radio frequency tag card authentication to unlock, and the information of the tag card is easily obtained and copied by the card reader. environment, so there will be great security risks. Contents of the invention [0004] The purpose of the present invention is to provide a frequency electromagnetic lock, which can realize one-to-one matchi...
