WIPO Patent Application WO/2020/211832
Kind Code:
A1
Abstract:
A method for detecting a space congestion degree and a method for scheduling an elevator car. The method for detecting a space congestion degree comprises: emitting a first wireless wave signal to a space, the space being divided into at least two detection sections and used for carrying a target object; receiving a second wireless wave signal, the second wireless wave signal being a wireless wave signal generated after the first wireless wave signal is reflected by the target object; determining, on the basis of the first wireless wave signal and the second wireless wave signal, a position where the target object is located in the space; determining, according to the position, a detection section where the target object is located in the space; and determining a congestion degree of the target object in the detection section on the basis of echo reflection intensity of the second wireless wave signal.
