Abstract

The invention relates to a passive intelligent electronic lock based on NFC (Near-Field Communication) electromagnetic field charging, and is designed by aiming at the technical problem that an existing intelligent lock product using an NFC technology needs battery or external power supply. The passive intelligent electronic lock consists of a casing, an NFC antenna, a circuit board and a switch lock executing mechanism, wherein the NFC antenna is arranged on the casing; the circuit board is arranged in the casing and is connected with the NFC antenna; and the switch lock executing mechanism is connected with the circuit board. The passive intelligent electronic lock is characterized in that the casing is made of non-metallic materials; the NFC antenna is arranged at the surface of the casing; the circuit board is provided with a control unit, an NFC data communication unit and temporary energy storage units; the switch lock executing mechanism comprises an unlocking / locking executingunit, a state detection unit, a locking clamp buckle and a standby unlocking mechanism; and the temporary energy storage units are conventional capacitors and circuits thereof, so that in the communication connection process, the NFC data communication unit performs energy collection and storage on an NFC signal electromagnetic field provided by upper end equipment with an NFC function, and provides energy for the action of the unlocking / locking executing unit.

Description

technical field

[0001] The invention relates to the field of near-field communication and the field of electronic locks, and is a passive intelligent electronic lock based on the use of NFC technology for communication and the use of electromagnetic field energy collection and power collection of NFC signals. Background technique

[0002] Today, with the rapid development of science and technology, smart electronic locks are more and more recognized by the public, and have played a huge role in various fields, while passive electronic locks refer to a kind of smart electronic locks that have no battery or other power supply inside. NFC (Near Field Communication) is a device (such as a smartphone) that uses NFC technology to exchange data when they are close to each other. It is an evolution from the integration of non-contact radio frequency identification (RFID) and interconnection technologies. The new technology integrates the functions of inductive card reader, inductive...
