electronic key

Abstract

The invention relates to an electronic key which comprises a circuit control unit and an unlocking unit. The circuit control unit is provided with a display unit, a keying unit, a storage unit and a power management unit which are respectively connected with a microprocessor. A coil output unit is in input connection with the microprocessor through a signal receiving unit, the microprocessor is in output connection with the coil output unit through a power amplifying unit, and the coil output unit is provided with a transmitting coil for transmitting signals. The electronic key adopts the transmitting coil to transmit communication data and supply power to a lock body, and a key head is not contacted with the lock body, so that various disadvantages caused by mutual contact are overcome. In addition, by arranging the electronic key, one electronic key can authorize and shield multiple assigned lock bodies, can effectively prevent illegal unlocking behaviors including imposed pulling and rotation to an unlocking shaft and the like through an anti-pulling spring and a relevant structure and has good anti-theft effect.

Description

technical field [0001] The present invention relates to electronic keys. Background technique [0002] Traditional multi-lock management currently adopts the following methods: one-to-one management (one key corresponds to one lock) and one-to-many management (one key corresponds to multiple locks, the so-called "open lock"). One-to-one management requires managers to carry multiple keys when managing a large number of locks. Therefore, we often see managers holding a chain of keys ranging from a dozen to hundreds, which is very difficult to use and manage. Convenience. Later, in order to facilitate management, one-to-many management (pass unlocking) was used. One key is used to manage multiple locks, and the problem is that one key can open many locks. If the key is stolen, lost, or the management fails, all the corresponding locks may be opened without authorization. This situation has caused serious management hidden dangers. With the development of science and techno...

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
