Embodiment 1

[0042] The invention expresses the unlocking information of the electronic lock in a group of combinations of different forces. The electronic lock only needs to learn a certain combination once, and the combination can have unlocking authority. The present invention obtains the combination of different magnitudes of force by means of the attractive force generated by the magnet and the magnetic permeable material. Since the attractive force between the magnet and the magnetic material is related to the distance between the two and the area of ​​action, this program can make the distance between the magnet and the magnetic material The attraction force of is changed regularly, so that we can regularly obtain multiple combinations of forces of different sizes. The microprocessor of the electronic lock cannot turn the combination of different forces into available unlocking information. The high-precision mechanical sensor can convert the gravitational force between the magnet ...

Embodiment 2

[0057] This embodiment provides a method for unlocking by magnet attraction, the method for unlocking by magnet attraction is as follows: image 3 shown, including:

[0058] The step of learning, that is, before unlocking, the system that utilizes magnet attraction to realize unlocking learns the information contained in the unlocking card; the learning steps are as follows: Figure 4 shown, including:

[0059] S1, read the unlocking card information, convert the attractive force between the magnet and the magnetic permeable material into an electrical signal and transmit the electrical signal;

[0060] S2. After processing the information in the unlocking card, analyze the card serial number of the unlocking card, learn the unlocking card information and save the unlocking card information, and the card serial number obtains the unlocking authority.

[0061] Steps to unlock; the steps are as follows Figure 5 shown, including:

[0062] S1', read the unlocking card informa...

Abstract

The invention provides a system and a method for unlocking by using magnetic pull, the system comprises a unlocking card, a card information reading module, a card information preprocessor module, an analysis processing module, a unlocking module and a man-machine information exchange module; wherein the card information reading module is used for reading the information of the unlocking card; the card information preprocessor module is used for processing the unlocking card information after receiving an electric signal and analyzing a card serial number of the unlocking card, and transmitting the unlocking card serial number; the analysis processing module is used for receiving the unlocking card information transmitted by the card information preprocessor module and then learning the unlocking card information, and then determining that whether the information obtained by the card information preprocessor module couples with the preserved unlocking card information or not. The system and the method for unlocking by using magnetic pull can omit the problem for carrying a lot of keys. If the key is lost, a new key is rearranged, the original key information record in the electronic lock can be deleted, the security is higher, and the cost of the key used by the electronic lock is relatively low.

Description

technical field [0001] The invention relates to an unlocking system and an unlocking method, in particular to a system and a method for realizing unlocking by using magnet attraction. Background technique [0002] Since ancient times, the world of Great Harmony has been the ideal world that human beings have actively pursued. However, it has been unable to achieve it because of the inherent greed of human beings. In the early days, due to the lack of human living materials and the constraints of effective moral forces, there was still a world of Datong such as going out without closing the door. With the gradual increase of material desires and the lack of moral restraint, locks have become an indispensable necessity in life. Locks are an important barrier to our privacy. The traditional mechanical lock, including the lock assembly and the key, unlocks the lock through the cooperation of the key and the keyhole of the lock assembly. Since the tooth pattern of the key is ea...
