A kind of NFC intelligent opening and closing lock control device and system, control method

Abstract

The invention discloses an NFC intelligent opening and closing lock control device, system and control method. The NFC intelligent unlocking and locking control device includes a controller and an NFC reader-writer; the controller includes a power supply for providing power to the controller, a power management circuit, a microprocessor, an internal memory connected to the microprocessor for information storage, The driving control circuit of the external lock, the sensor signal processing circuit of the state sensing signal of the external induction lock, the antenna board 1, the NFC module 1, the NFC signal detection circuit; the NFC reader includes the power supply for the NFC reader 2, the antenna Board two, NFC module two. Unattended locking process of the present invention can be unattended, which reduces the interference of human operation on confidential materials; in the process of opening and closing, abnormal actions and illegal actions are recorded or illegal operations are recorded and stored to realize self-monitoring; the working current is small, and the lock The core drive structure only needs to be powered on when it is in motion, and the state remains without power consumption. The standby power of the whole machine is low and the battery life is long; the invention is efficient and safe.

Description

technical field [0001] The present invention relates to an automatic opening and closing lock system, and more specifically, relates to an NFC intelligent opening and closing lock control device, system, and control method. Background technique [0002] NFC is the abbreviation of Near Field Communication, that is, short-range wireless communication technology. NFC, jointly developed by Philips and Sony, is a contactless identification and interconnection technology that enables short-range wireless communication between mobile devices, consumer electronics, PCs and smart control tools. NFC provides a simple, touch-sensitive solution that allows consumers to exchange information, access content and services simply and intuitively; NFC chips are capable of communicating with each other, and have computing power, and also contain encryption logic in the Felica standard circuit, the later standard of MIFARE also added encryption / decryption module (SAM). [0003] In the process...

AI Technical Summary

Problems solved by technology

[0005] (1) If the traditional key is used to open and close the lock, the process cannot be fully automatic and unattended, and there is a possibility of artificial interference with confidential materials, and the key may be artificially copied, resulting in the inability to completely keep secret during the process;

[0006] (2) Information cannot be carried, or information such as QR codes may be artificially exchanged during the process;

[0007] (3) Unable to self-monitor the intermediate process;

[0008] (4) Cannot be reused
