Problems solved by technology

[0002] With the development of the market economy, more and more power boxes appear in public places. Now the power boxes are basically locked by ordinary locks through keys. Use the corresponding key to unlock the lock for maintenance, the key is troublesome to carry and easy to cause loss and duplication, which is more likely to cause potential danger
In addition, the existing electronic locks need to be powered all the time to respond to the unlock command at any time. If the power supply is disconnected or the battery is damaged, it will not respond, the reliability is low, and it is inconvenient to manage and maintain.

Abstract

The invention provides a passive NFC cloud lock system. The passive NFC cloud lock system comprises a passive NFC cloud lock terminal, a mobile terminal and a cloud platform management system; the passive NFC cloud lock terminal comprises an NFC module, an antenna, a rectification module, a charging switch, an energy storage module, a voltage stabilization module, a storage module and an MCU. The MCU is provided with a power supply unit, an ADC unit and a PWM unit. The mobile terminal is used for generating a magnetic field when approaching the antenna so that the antenna can collect energy, the mobile terminal is further used for carrying out near field communication with the passive NFC cloud lock terminal through the NFC module, and the mobile terminal is further used for carrying out communication with the cloud platform management system. The NFC cloud lock terminal is started by collecting the NFC signal energy close to the mobile terminal, communication between the NFC cloud lock terminal and the cloud platform management system is achieved, and therefore the unlocking function can be achieved under the condition that a key is not needed and power supply does not need to be kept.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a passive NFC cloud lock system. Background technique [0002] With the development of the market economy, more and more power boxes appear in public places. Now the power boxes are basically locked by ordinary locks through keys. Follow the corresponding key to unlock the lock for maintenance, the key is troublesome to carry and is easy to cause loss and duplication, which is more likely to cause potential danger. In addition, the existing electronic locks need to be powered all the time to respond to the unlocking command at any time. If the power supply is disconnected or the battery is damaged, it will not respond, the reliability is low, and it is inconvenient to manage and maintain. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a passive NFC cloud lock system, so that the unlocking function can be reali...
