Title:
BIOLOGICAL INFORMATION DETECTION DEVICE
Document Type and Number:
Japanese Patent JP2023104063
Kind Code:
A
Abstract:
To provide a biological information detection device capable of detecting biological information on a crew member of a movable body with a high degree of precision.SOLUTION: A biological information detection device includes: a sensor for transmitting a transmission wave and receiving a reflection wave generated when the transmission wave is reflected by an object present in a room; a position information generation unit for generating position information indicating the position of the object in the room on the basis of the reflection wave; a velocity information generation unit for generating velocity information indicating the velocity of the object on the basis of the reflection wave; a person detection unit for detecting a person present in the room on the basis of the position information and the velocity information; a sub-velocity information generation unit for generating sub-velocity information indicating the velocity corresponding to a motion of a part of the person's body on the basis of a sub-beat frequency component that does not include a main beat frequency corresponding to a maximum peak in the beat frequency intensity distribution indicating relationships between a beat frequency based on a difference between the frequency of the transmission wave and the frequency of the reflection wave, and the intensity of the reflection wave; and a biological information generation unit for generating biological information on the person on the basis of the sub-velocity information.SELECTED DRAWING: Figure 2
