Electronic door lock access control system

Abstract

This invention provides an electronic door lock access control system, comprising a rental management platform, an electronic door lock, an access control unit, a password generation unit, and a communication unit. The rental management platform manages the lease status and rent payment status, and links data with the electronic door lock. When the lease is in effect, the access rights to the electronic door lock can be transferred or authorized to the tenant based on the lease status. When the rental management platform determines that the tenant's rent payment status meets a preset access control condition, the access control unit can restrict some unlocking methods of the electronic door lock, and the password generation unit automatically generates a random password as the specific unlocking method. If the rent arrears status remains unresolved, the password generation unit can automatically increase the number of digits in the random password based on the number of days elapsed, with a preset upper limit for the number of digits. Therefore, this invention links the unlocking permissions of the electronic door lock with the lease and rent payment status, and improves rental management efficiency and door lock access control security through gradual access control adjustments and dynamic password management.
