Abstract

A display device includes a display controller and displays a content based on display signals output from the display controller. The display controller includes: a gauge value converter that converts measurements of a plurality of devices displayed in a predetermined unit into gauge values with the same scale; and a maximum gauge value determiner that determines a maximum one of the gauge values converted by the gauge value converter, so as for the gauge value determined by the maximum gauge value determiner to be displayed.

Claims

1. A display device for a construction machine comprising a display controller and displaying content based on display signals output from the display controller,

the display controller comprising:

a value converter that converts a plurality of measurements displayed in a predetermined unit into different values with a same scale; and

a value determiner that determines one of the different values converted by the value converter according to a predetermined criterion,

the one of the different values determined by the value determiner being displayed on a display unit.

2. The display device for a construction machine according to claim 1,

wherein the plurality of the measurements comprise different display ranges.

3. The display device for a construction machine according to claim 1,

wherein the plurality of the measurements belong to a same group in which the measurements are related to one another.

4. The display device for a construction machine according to claim 3, wherein the same group is an electrical group.

5. The display device for a construction machine according to claim 1,

wherein the measurements are temperatures and

a cooling water temperature display unit that displays cooling water temperatures of engine cooling water is provided separately from the display unit.

6. The display device for a construction machine according to claim 1,

wherein the plurality of the measurements are displayed in a same unit.

7. The display device for a construction machine according to claim 1,

wherein the value determiner determines a maximum one of the different values as the one of the different values.

8. The display device for a construction machine according to claim 1,

wherein the value determiner determines any selected one of the different values as the one of the different values.
