LoRa-based intelligent centralized access control system for college dormitory

Abstract

The invention discloses a LoRa-based intelligent centralized access control system for a college dormitory. The LoRa-based intelligent centralized access control system comprises a wireless access control device, a LoRa gateway, a network server and an online management platform. The wireless access control device is installed on a dormitory door. A fingerprint identifier, a card reader and a mechanical lock are arranged out of the door. A LoRa module, a control module and a power module are arranged in the door. A battery supplies power. When the LoRa-based intelligent centralized access control system works, point-to-point wireless communication of information between the wireless access control device and the LoRa gateway in a dormitory building is realized through the LoRa technology;the LoRa gateway is connected to the network server; and the network server is connected with the online management platform in a dormitory management center. The LoRa-based intelligent centralized access control system of the invention has altogether three identification modes, i.e., key identification, campus card identification and fingerprint identification, records door opening and closing operations and personnel information, realizes centralized management of massive dormitories through the LoRa wireless communication technology, can open a door remotely, effectively protects dormitorysafety and reduces dormitory management cost.

Description

technical field [0001] The invention relates to the field of dormitory access control management, in particular to a LoRa-based centralized access control management system for intelligent university dormitories. Background technique [0002] At present, the more popular unlocking methods of college dormitory access control systems are keys and campus cards, that is, various smart induction cards. However, keys and campus cards are often lost or forgotten by students in the dormitory, so the mainstream unlocking methods are not safe and convenient. . [0003] In recent years, households have become popular to use smart electronic locks with fingerprint recognition. However, college dormitories are not as fixed as household fingerprint lock users and need to be replaced frequently. However, there are many college dormitories, and it is cumbersome to replace the fingerprints of each dormitory fingerprint lock separately. . [0004] Patent CN107918967A discloses a campus dorm...

AI Technical Summary

Problems solved by technology

ZigBee technology has shortcomings such as short transmission distance, need to increase routing in networking, is easily affected by the environment, and the information transmission is not stable enough. It is not suitable for domestic university dormitories with a large number of dormitories and wide distribution of dormitory buildings, as well as access control applications with high security requirements.
