Problems solved by technology

Although the information of the existing two-dimensional code is encrypted, the validity period of the encryption is also limited. Once copied within the validity period of the two-dimensional code, it also has the function of taking the elevator, which reduces the safety of the elevator.

Abstract

The invention relates to an elevator calling method and device based on QR codes. The elevator calling method comprises the following steps: acquiring QR code data and first random data which are sentby a terminal; parsing the QR code data, so as to obtain first elevator calling information and second random data; comparing the first elevator calling information with second elevator calling information; when the first elevator calling information and the second elevator calling information are consistent, judging whether the first random data and the second random data are matched or not; andwhen the first random data and the second random data are matched, controlling an elevator car to stop on a specified floor. By the adoption of the elevator calling method, the elevator taking QR code safety can be enhanced, the offline QR code anti-counterfeiting effect can be achieved, and the QR code anti-counterfeiting performance can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to an elevator calling method, device, computer equipment and storage medium based on a two-dimensional code. Background technique [0002] Elevators are already a product that people often come into contact with in their lives. Whether as a visitor user or a resident user, they have the opportunity to take the elevator every day. [0003] The two-dimensional code is more and more widely used in building security and access control systems, especially in elevator systems. However, the cost of copying the QR code is low, and it can be copied by taking a screenshot. Although the information in the existing two-dimensional code is encrypted, the validity period of the encryption is also limited. Once copied within the validity period of the two-dimensional code, it also has the function of taking the elevator, which reduces the safety of taking the elevator. Contents of ...
