Abstract

The invention relates to a novel elevator external call auxiliary device and a method thereof. The elevator external call auxiliary device comprises a video acquisition module and a video processing module, wherein the video acquisition module comprises a camera which is arranged above the doorway of an external hall of an elevator, shoots reference pictures when no people or objects are waiting for the elevator or real-time pictures in other states, and transmits the pictures to the video processing module in real time; the video processing module caches the pictures and performs subtraction on each frame of the pictures and the reference pictures so as to judge whether the people or the objects are waiting for the elevator; and if the people or the objects are waiting for the elevator, a signal transmission module outputs call signals to an elevator external call box and then the elevator external call box outputs the call signals to an elevator main control cabinet, or the call signals are directly output to the elevator main control cabinet, and the elevator main control cabinet controls an elevator tractor. The elevator external call auxiliary device or the method is a supplement to the conventional call mode, and under a condition with a certain special staff or under certain special conditions, a passenger can fulfill the aim of calling the elevator without pressing a call button.

Description

technical field [0001] The invention belongs to the technical field of elevator control, and relates to an auxiliary calling device and method for extending the function of an elevator calling box. Background technique [0002] An elevator is a lifting device that moves vertically and is used to carry people or goods. When the user needs to take the elevator, he must press the up or down button on the call panel outside the elevator hall to realize the call to the elevator. [0003] At present, the call switch outside the elevator hall mostly uses buttons as the device to trigger the call action. The action of pressing the button requires a person to approach the call panel and press the corresponding button. The button surface drives the micro switch inside the button to connect the circuit through the connecting mechanism to achieve Call purpose. This way of calling elevators does not have any problem for ordinary passengers, but for some special personnel or all but bri...
