Title: Control system of elevator
Inventor: SUDO TAKESHI
IPC: B66B1/18
Filed: 2022-03-16
Abstract: To provide a control technique that enables landing call utilizing a face-authentication technique to be automatically allocated and enables a burden on a supervisor that may be caused by the automatic allocation to be reduced and convenience for an elevator user to be improved.SOLUTION: In a control system of an elevator, a face-authentication processing part determines whether or not face information obtained by a face-information obtaining part matches any of registered face-information. When the face- authentication processing part determines that "the face information does not match any of the registered face information", a control processing part enables a registering part to select an option concerning user registration. When the registering part selects a first option, the control processing part sets a destination floor registered by the registering part as a default floor, and registers the face information while associating the face information with the default floor. Further, when the face-authentication processing part determines that "the face information matches any of the registered face information" and when the default floor corresponding to the face information is the destination floor, the control processing part performs allocation of landing call to an elevator car, using the default floor.SELECTED DRAWING: Figure 1
