Embodiment Construction

[0043] Combine below Figure 1 to Figure 3 The lock provided by the invention is introduced in detail. The matched key in the embodiment of the present invention adopts such as figure 1 The card-type electronic key shown in , this embodiment will be described with the electronic key and the matching electronic lock as an example.

[0044] Such as figure 2 The principle diagram of the lock of the present invention is shown, and the matched electronic key 200 is also shown in the figure. in:

[0045] The electronic key 200 includes a radio frequency induction antenna, a control module and a chip (not shown) that store unlocking data and are sequentially connected. The unlocking data includes an electronic key ID and / or an unlocking code word and the like. The radio frequency induction antenna generates electric current for the electronic key 200 through electromagnetic induction with the electronic lock 100 , and the control module processes the unlocking data in the chip ...

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...
