Anti-duplication quick response code elevator calling method and device

Abstract

The invention discloses an anti-duplication quick response code elevator calling method and device. The elevator calling method comprises the steps that a visitor sends an elevator taking applicationthrough a mobile terminal, and a cloud server generates and gives an initial verification quick response code to the visitor after the elevator taking application is determined by a proprietor or management personnel and registers visitor information; an elevator calling unit reads the visitor quick response code and transmits visitor elevator taking information to the cloud server through an elevator system, the cloud sever judges whether the quick response code belongs to the initial verification quick response code or not, if the quick response code belongs to the initial verification quickresponse code, a repetitive verification quick response code is generated and automatically refreshed to visitor mobile terminal equipment, and the repetitive verification quick response code is transmitted to the cloud server again through the elevator system and judged; and if the cloud sever judges the quick response code belongs to the repetitive verification quick response code, visitor elevator taking information is sent to the elevator system, floor information is registered, and the elevator is controlled to open a door. According to the anti-duplication quick response code elevator calling method and device, the cloud server generates and verifies the quick response code information twice, the condition that the information is not duplicated and usurped is ensured, and security protection function of elevator calling of the elevator is realized.

Description

technical field [0001] The invention relates to the technical field of elevator intelligent control, in particular to a method and device for calling an elevator with an anti-duplication two-dimensional code. Background technique [0002] With the development of society, the advancement of science and technology, the popularization of the use of two-dimensional codes, the development of intelligent elevators, the two-dimensional code calling elevator technology came into being. The prior art solution is that the hall call system of the elevator has a two-dimensional code identification function, and the elevator hall call is called by identifying the special two-dimensional code. Among them, the special QR code is a QR code generated in advance or generated in real time. As long as the elevator system reads the correct QR code information, it will control the elevator response and make the elevator open the door, but it is impossible to judge whether the QR code comes from a...

Problems solved by technology

Among them, the special QR code is a QR code generated in advance or generated in real time. As long as the elevator system reads the correct QR code information, it will control the elevator response and make the elevator open the door, but it is impossible to judge whether the QR code comes from a real visitor. Unable to identify whether the QR code has been copied or stolen

Thereby reducing the security function of the elevator, or even completely failing the security function of the elevator
