Title:
WORK MACHINE AND WORK MANAGEMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/080793
Kind Code:
A1
Abstract:
A work machine having as the purpose therefor the capability to readily and with high precision measure the number of times that a sequence of digging and loading mechanism operations, such as loading work, occurs, and manage work on the basis of the measurement results. The work machine: calculates a time-integrated value that time-integrates a physical amount output in accordance with the operation of an operation lever; associates the time-integrated value and a prescribed operation angle of the digging and loading mechanism that is consequent upon the operation of the operation lever; determines, if the time-integrated value is at least a prescribed integrated value, that the operation lever has been operated; and, if each determined operation of the digging and loading mechanism has occurred in a prescribed order, cumulatively adds, counting the number of loadings as one time. The work machine comprises: a predetermined value setting unit (62) that sets the bucket capacity; a job amount calculation unit (63) that calculates a job amount, said job amount being the number of loadings multiplied by the bucket capacity; and an I/O unit (66) that displays and outputs at least a job rate.
