Document Type and Number:
Japanese Patent JP2022131962
Kind Code:
A
Abstract:
To provide a detector that can accurately determine an object approaching an elevator.SOLUTION: A detector 100 comprises at least one sensor 1, a signal processing unit 2, and a speed determination unit 4. The at least one sensor 1 receives reflected waves of a radio wave from a plurality of directions and outputs a plurality of sensor signals according to the plurality of reflected waves. The signal processing unit 2 determines the speeds of travel of object corresponding to the plurality of directions based on the plurality of sensor signals. The speed determination unit 4 determines whether an object 400 approaches a predetermined target position P1 based on the plurality of travel speeds. The plurality of directions include a first direction A1 and a second direction A2 being directions directed to a first door 61 and a second door 62 of a double-door structure of an elevator 6.SELECTED DRAWING: Figure 1
