Description

Technical Field

[0001] The present invention relates to the technical field of elevator control, and particularly to an elevator call device and a call control method based on voice interaction. Background Art

[0002] Before taking an elevator, people need to perform a call operation on the elevator, and then the elevator dispatching system will dispatch the elevator based on the call instruction input in the passenger call operation, so that the elevator reaches the floor designated by the user.
