Title:
OPERATION DATA STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/179918
Kind Code:
A1
Abstract:
This operation data storage device for storing operation data of a hydraulic shovel provided with an articulated front work machine is configured from a storage controller provided with a volatile storage unit and a non-volatile storage unit. The operation data storage device is programmed to store operation data including: operation amount data representing the content of an input operation performed by the operator of the hydraulic shovel using an electric operating lever; and operation amount data representing an amount of operation performed by an operating member constituting an element of the front work machine, said operating member operating in response to said input operation. When in an initial state, the operation data storage device stores the operation data in the volatile storage unit, and then if an attitude parameter detected by an attitude detection sensor provided to the hydraulic shovel exceeds a predetermined attitude threshold value, the operation data storage device generates a save storage signal, and switches to writing the operation data to the non-volatile storage unit, instead of the volatile storage unit, in accordance with the save storage signal.
