Description

Door opening method and device, access device and computer readable storage medium

This application claims priority to Chinese Patent Application No. 201710917206.4, entitled "Opening Method and Device, Access Control Device and Computer-Readable Storage Media", filed on September 30, 2017, the entire contents of which are hereby incorporated by reference. The citations are incorporated herein by reference.

Technical field

The present invention relates to the field of security protection technologies, and in particular, to a method and device for opening a door, an access device, and a computer readable storage medium.

Background technique

In recent years, hotel intelligence has become more and more popular, but the existing hotel intelligent unlocking system is generally used for conventional fingerprint unlocking and password unlocking. For example, the hotel device allocates a first unlocking password corresponding to the room information in the check-in confirmation information based on the acquired check-in confirmation information, and changes the state of the room information to a check-in state. The hotel device sends the room information and the first unlocking password to a corresponding mobile device, and sends the check-in state and the first unlocking password to a door lock terminal corresponding to the room information. The door lock terminal receives a second unlocking password from the mobile device, and the door lock terminal matches the first unlocking password and the second unlocking password according to the check-in state, and determines whether to open the door according to the matching result. In addition, the hotel equipment may also cancel the first unlock password of the allocated corresponding room based on the acquired check-in information, and simultaneously transfer the status of the room information from the check-in state, and then turn The outgoing status is sent to the door lock terminal, and further, the door lock terminal determines that the first unlock password is an invalid password.

The above conventional fingerprint unlocking and password unlocking have certain shortcomings. When the hotel uses conventional fingerprint unlocking, the fingerprint information is easily copied and stolen, and the security needs to be further improved.
