Title:
LOADING WEIGHT DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/060319
Kind Code:
A1
Abstract:
Provided is a loading weight detection device which is applicable to a wide variety of mobile objects and is able to accurately detect a loading weight with a smaller number of input variables.
A loading weight detection device is provided with: a touch panel (33) which accepts inputs of a tare (ma) and an initial setting freight weight (mb0); a shaking detection unit (20) which detects the shaking of a freight vehicle; a computing unit (31) which functions as a natural vibration specification means for specifying, as a pitching natural vibration value, natural vibration in an empty weight direction on the basis of shaking data detected by the shaking detection unit (20); and a storage unit (32) which stores, as initial setting data, the tare (ma) and the initial setting freight weight (mb0) together with the pitching natural vibration value specified by the computing unit (31) in a state where the freight vehicle is loaded with freight with the initial setting freight weight (mb0), and the computing unit (31) computes a total weight (M) on the basis of the specified pitching natural vibration value and the initial setting data.
