Title:
WORK MACHINE AND WORK VOLUME MEASUREMENT METHOD FOR WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2014/080805
Kind Code:
A1
Abstract:
A work machine that, in order to readily and with high precision measure the number of times a sequence of digging and loading mechanism operations such as digging and loading work occurs, comprises: an operation state detection unit (31a) that detects the physical amount output in accordance with the operation of operation levers (41, 42); a time integration unit (31b) that calculates a time-integrated value being a time-integration of the physical amount; a determination unit (31c) that associates the time-integrated amount and a prescribed operation angle of the digging and loading mechanism consequent upon the operation of the operation levers (41, 42) and, if the time-integrated value is at least a prescribed integrated value, determines that the operation levers (41, 42) have been operated; and a counting unit (31d) that, if each operation of the digging and loading mechanism that has been determined by the determination unit (31c) has occurred in a prescribed order, counts the number of times the sequence of digging and loading work has occurred, counting as one time digging and loading mechanism operations that have occurred in the prescribed order.
