Intelligent lock, intelligent key and bidirectional interaction control method thereof

Abstract

The invention discloses an intelligent lock and a corresponding intelligent key. The intelligent key transfers energy by use of a transmitting coil; the intelligent lock does not need a power supply inside, and receives the energy transferred by the intelligent key through a receiving coil to supply power to an unlocking control mechanism in a lock body; without contact of a contact electrode, the potential safety hazard caused by bad environment is avoided; the invention also provides a bidirectional interaction control method between the intelligent lock and the intelligent key, wherein the method can realize bidirectional verification between the intelligent lock and the intelligent key; a user can set the authority according to the practical need, thus the management is more convenient; and moreover, if the key is lost or illegally copied or a specific key needs to be canceled, the lockset is subjected to blacklist operation by use of an authorization device to record the specific key into the blacklist of the lockset, and then the specific key can not be used, thereby realizing higher safety. The invention is applicable to various users, particularly to users in charge of a great quantity of lockset.

Description

technical field [0001] The invention relates to a lock and a key for opening and closing the lock, in particular to an intelligent lock, an intelligent key, and a two-way interactive control method between the intelligent lock and the intelligent key. Background technique [0002] Locks are widely used as a means of anti-theft and privacy protection, and a large number of locks need to be applied in many industries, such as: offices of enterprises and institutions, warehouses, doors, cabinets, boxes for important materials, municipal, Meter boxes, ring network cabinets, wiring boxes, valve boxes, light pole hatches, etc. in industries such as electricity, tap water, and gas; this involves how to manage many locks. The current methods are: one-to-one management (one key corresponds to one lock) and one-to-many management (one key corresponds to many locks, the so-called "open lock"). One-to-one management requires managers to carry multiple keys when managing a large number ...

Problems solved by technology

However, because this method uses contacts for power supply and communication, the contacts are prone to rust, oxidation, and fouling in environments with high humidity, dust, and heavy salt fog, resulting in poor contact. Use in an explosive gas environment may cause accidents due to poor contact and sparks
