Abstract

A state information display for a work machine displays plural kinds of state information of the machine including first and second state information, and includes: a state information displaying unit defining first and second display areas respectively displaying the first and second state information; and a display controller controlling the entire display including the unit and including: a malfunction information determining unit receiving the plural kinds of state information and determining whether or not the state information includes malfunction information indicating a malfunction of the machine; a first display switching unit switching the first state information in the first display area with a caution sign for reporting the malfunction, when the unit determines the malfunction information is received; and a second display switching unit switching the second state information in the second display area with the first state information, when the first state information is switched with the caution sign.

Claims

1. A state information display for a work machine, the state information display being provided to the work machine to display plural kinds of state information of the work machine comprising first state information and second state information, the state information display comprising:

a state information displaying unit defining a first display area that displays the first state information and a second display area that displays the second state information; and

a display controller configured to control the state information displaying unit, the display controller comprising;

a malfunction information determining unit configured to receive the plural kinds of state information and determine whether or not the plural kinds of state information comprise malfunction information indicating a malfunction of the work machine;

a first display switching unit configured to, based on the malfunction information determining unit determining that the malfunction information is received, switch the first state information displayed in the first display area with a caution sign for reporting the malfunction information determined to be comprised in the plural kinds of state information by the malfunction information determining unit; and

a second display switching unit configured to, based on the first display switching unit switching the first state information with the caution sign, switch the second state information displayed in the second display area with the first state information.

2. The state information display for the work machine according to claim 1, wherein each of the first state information and the second state information is numerical information.

3. The state information display for the work machine according to claim 1, wherein the first display area is larger than the second display area.

4. The state information display for the work machine according to claim 1, wherein

the plural kinds of state information further comprise third state information,

the state information displaying unit further defines a third display area that displays the third state information, and

the display controller further comprises a third display switching unit configured to, based on the malfunction information determining unit determining that the malfunction information is received, switch the third state information displayed in the third display area with a malfunction level sign, the malfunction level sign indicating a level of the malfunction related to the caution sign displayed in the first display area.

5. The state information display for the work machine according to claim 1, wherein

the caution sign comprises a plurality of caution signs,

the malfunction information comprises plural kinds of malfunction information, and

based on the malfunction information determining unit receiving ones of the plural kinds of malfunction information, the first display switching unit displays ones of the plurality of caution signs in accordance with the received ones of the plural kinds of malfunction information.

6. A caution-sign displaying method for a work machine, the method being configured to allow a state information display provided to the work machine to display a caution sign, the state information display being configured to display plural kinds of state information of the work machine comprising first state information and second state information, the state information display comprising:
