Problems solved by technology

[0003] In order to overcome the above-mentioned deficiencies, the object of the present invention is to provide the field with a passive intelligent electronic lock that does not require internal batteries and external power supply, is based on NFC communication, and is powered by the electromagnetic field energy collection of NFC signals, so that it can solve the current problems. Some smart lock products using NFC technology need batteries or external power supply, and the batteries in the products need to be charged or replaced. The maintenance cost is high, and there is a lack of power storage through NFC technology, and there are few technical problems in passive structure design.

Embodiment 1

[0020] Such as figure 1 As shown, the specific structure and function of each module in the figure are as follows:

[0021] 1. Upper-end equipment with NFC function: including smartphones, PDAs, etc. and related applications (APP software) installed in them. When the user opens and closes the lock, the APP software will call the NFC and NFC in the upper-end equipment with NFC function according to the user's operation. For lock communication, when communicating with the lock, the NFC antenna area of ​​the upper-end device with NFC function needs to be close to the NFC antenna area of ​​the lock.

[0022] 2. NFC antenna: It is used for the actual circuit signal sending and receiving part of the NFC data communication unit in the lock to communicate with the smart phone, and is also responsible for the electromagnetic field energy coupling collection of the NFC signal of the upper-end device with NFC function. The NFC antenna consists of a coil wound by a metal wire or made of ...

Embodiment 2

[0034] Embodiment 2: In the provided passive intelligent electronic lock device based on the NFC electromagnetic field to take power, the locking buckle that the user unlocks is transformed into a handle or handle.

Embodiment 3

[0035] Embodiment 3: In the provided passive intelligent electronic lock device based on the NFC electromagnetic field to take power, there is no spare unlocking mechanism design in the lock structure. All the other are with embodiment 1 or embodiment 2.

[0036] To sum up, the passive intelligent electronic lock is a battery-free and external power supply interface, which drives the internal structure to execute the switch lock by collecting and storing the energy radiated from the NFC communication port of the upper-end device with NFC function. , an intelligent lock with unlocking / locking actuator, lock status monitoring, and backup unlocking mode. The passive smart electronic lock is aimed at the existing smart locks that use an external power supply line, which cannot be portable, or the battery contains high battery maintenance costs in the lock, and there are safety hazards such as transportation, or the interior contains wireless power supply and other solutions. Lock...

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...
