Lock, key and unlocking method

Abstract

The invention relates to a lock which comprises a key detection module, a control module and a radio frequency induction antenna, wherein the key detection module is used for outputting a specific number of level signals when a key is correctly placed into a specific position on the lock; the control module is connected with the key detection module, and is used for controlling the radio frequency induction antenna to enter a working mode when the level signals are received in a certain time and controlling to unlock according to unlocking data of the key, which is uploaded by the radio frequency induction antenna; and the radio frequency induction antenna is connected with the control module and is used for receiving the unlocking data of the key and uploading the unlocking data of the key to the control module when controlled to enter the working mode by the control module. The invention further correspondingly provides an unlocking method of the key. After the lock and the unlocking method are used, the energy consumption of the lock can be reduced.

Description

technical field [0001] The invention relates to a lock, key and unlocking method based on radio frequency identification technology. Background technique [0002] Commonly used locks include mechanical locks and electronic locks. Among them, the mechanical lock is widely used because of its cheap price, but the structure of the mechanical lock is relatively simple, and the safety is not high. In addition, the lock head hole of the mechanical lock is exposed to the outside, rainwater is easy to enter the lock head, and the lock head will cause poor contact due to rust, which will affect its life and use. [0003] The electronic lock uses electronic signals to carry the unlocking data. Since the unlocking data can be set more complicated, it has higher security, and because its structure does not need to be exposed to the outside, it also avoids immersion in rainwater, and has a longer service life and is more convenient to use. [0004] Just disclose a kind of electronic lo...

AI Technical Summary

Problems solved by technology

[0005] However, the above-mentioned electronic lock using RFID technology has the following problems: because it uses radio frequency transmission, it needs the electronic lock to be in a charged state all the time to form a magnetic field for the electronic lock induction, so the energy consumption is relatively large
