Title:
DANGEROUS BEHAVIOR DETECTION DEVICE FOR WALKING WORK VEHICLE
Document Type and Number:
Japanese Patent JP2019033673
Kind Code:
A
Abstract:
To enable dangerous behavior such as dashing, jumping and overturning of a walking work vehicle to be more reliably detected.SOLUTION: A dangerous behavior detection device for a walking work vehicle comprises : an acceleration detection sensor detecting at least one of the longitudinal acceleration and the vertical acceleration of the walking work vehicle; a threshold determination unit 23 determining whether or not the acceleration after undergoing filtering processing by filter processing unit 22 exceeds a predetermined threshold; a frequency determination unit 24 determining whether or not the frequency at which the acceleration exceeds the predetermined threshold is a predetermined level or more; and a dangerous behavior detection unit 25 detecting the occurrence of the dangerous behavior in the walking work vehicle when determined that the frequency is the predetermined level or more. A rotational speed of a running wheel having a value being not greatly varied even if the dangerous behavior occurs is not detected, but acceleration having a value being greatly varied when the dangerous behavior occurs is detected, and the presence or absence of the occurrence of the dangerous behavior is determined on the basis of the detected acceleration, and accordingly the occurrence of the dangerous behavior can be detected more reliably.SELECTED DRAWING: Figure 2
