Title:
RESIDUAL OPERABLE TIME CALCULATION DEVICE FOR WORK MACHINE, RESIDUAL OPERABLE TIME CALCULATION METHOD FOR WORK MACHINE AND WORK MACHINE
Document Type and Number:
Japanese Patent JP2014238625
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a technology for immediately reflecting a change in the setting state of a work machine on the calculation of a residual operable time.SOLUTION: A hydraulic shovel 1 includes various processing parts having: a first arithmetic part 93; a second arithmetic part 95; and a correction part 97, and calculates the residual operable time of the hydraulic shovel 1 in a predetermined period. The first arithmetic part 93 divides the residual quantity of fuel by fixed time fuel consumption to temporarily calculate a residual operable time (F). The second arithmetic part 95 calculates a state corresponding fuel consumption estimation value (B) as a fuel consumption estimation value corresponding to the setting state of the hydraulic shovel 1 by referring to a fuel consumption estimation value table. The correction part 97 multiplies the residual operable time (F) by a ratio (A/B) of a previous fuel consumption estimation value (A) to the state corresponding fuel consumption estimation value (B) to correct the residual operable time (F).
