Document Type and Number:

WIPO Patent Application WO/2014/203990

Kind Code:

A1

Abstract:

This abnormality information control device is equipped with: an abnormality detection means that detects an abnormality of a device that is installed on a construction machine; an abnormality information output means that outputs the detected device abnormality information when in a normal mode, or nullifies or does not output the abnormality information when in a maintenance mode; and a mode-switching means that determines the content of a maintenance task and automatically switches between the normal mode and the maintenance mode in accordance with the content of the maintenance task or the circumstance. Consequently, since switching between the normal mode and the maintenance mode is automatically performed in accordance with the content of the maintenance task or the circumstance, only true abnormality information that is generated while in the normal mode can be output while the output of meaningless false abnormality information that is generated while in the maintenance mode is prevented.
