Embodiment 1
[0038] In one embodiment of the present invention, a call system based on a two-dimensional code is provided, see figure 1 , The two-dimensional code-based elevator calling system includes an elevator control module, a mobile terminal and a data management module. Preferably, the mobile terminal communicates with the data management module and the elevator control module in a wireless manner. The mobile terminal is provided with a camera, the mobile terminal sends a registration request to the data management module, the registration request includes user identity information, and the data management module returns an authorization code to the mobile terminal according to the registration request, based on the authorization Code, the mobile terminal can obtain the elevator operation graphical user interface by scanning the two-dimensional code;
[0039] The mobile terminal sends an operation instruction to the elevator control module through the interface, and the elevator con...
Embodiment 2
[0044] Different from Embodiment 1, the two-dimensional code in Embodiment 1 is displayed in a solid state, and the two-dimensional code can be obtained after obtaining the authorization code (even before obtaining the authorization code), while in this embodiment, all The system also includes a two-dimensional code display module 3, which does not display the two-dimensional code to the user under normal conditions, and only when the mobile terminal starts the scanning module for scanning the two-dimensional code, the data management module is triggered to send a verification request to the mobile terminal ; After the mobile terminal inputs the verification information and passes the verification, the data management module sends the two-dimensional code information to the two-dimensional code display module.
[0045] For its working timing, see figure 2 ,details as follows:
[0046] First, the mobile terminal sends a registration request to the data management module, and th...
Embodiment 3
[0048] The present invention provides an elevator, including a car and the two-dimensional code-based calling system described in Embodiment 1 or 2. In this embodiment, the two-dimensional code display module 3 is arranged on the operating panel 1 in the car, see image 3 , Preferably, the floor information on the operation panel 1 is consistent with the floor selection button information on the elevator operation graphical user interface, and when the floor selection button is pressed, the corresponding floor button 2 on the operation panel is lit. The floor information on the operation panel 1 is consistent with the floor selection button information on the elevator operation graphical user interface and can be achieved in the following manner: the two-dimensional code is correspondingly provided with the floor information on the operation panel 1, so that the mobile terminal scans the two-dimensional There is a corresponding button in the user interface obtained by the code...
