Abstract

The invention provides a LoRa-based encrypted access control system, which includes a LoRa door lock, a LoRa personal identification card, and a LoRa management terminal; the LoRa door lock includes a processor, a LoRa personal identification card for detecting a user, and a LoRa management terminal A LoRa module for communication, a storage module for storing the secret key of the paired LoRa personal identification card, and a first digital clock chip. The LoRa personal identification card includes a LoRa terminal node with a unique identity, and the LoRa management terminal performs pairing and time calibration on the LoRa personal identification card and the LoRa door lock. The technical scheme of the present invention adopts the non-contact mode to unlock the lock, which greatly increases the convenience; and adopts the encrypted pairing message transmission mode to ensure safety without the possibility of forged messages; and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, in particular to a LoRa-based encrypted access control system. Background technique [0002] With the rapid development of electronic information, the way of opening the door has developed from key opening to using NFC card, fingerprint recognition, face recognition and other technologies to open the door, and these technologies require direct contact. However, it takes a certain amount of time to open the door with keys, swiping cards or biometric technology, which is time-consuming. In addition, for groups such as children, the elderly, and the disabled, it may be inconvenient to open the door, and the security is not high. , are easily cloned. Contents of the invention [0003] Aiming at the above technical problems, the present invention discloses a LoRa-based encrypted access control system, which is easy to use, greatly increases convenience, and can ensure security and av...
