Abstract

To provide an operation vehicle monitoring device that can reduce man hours for maintenance and realize the maintenance efficiency, it includes an input unit (201) in which a signal for instructing registration of a selected monitoring item is input, a display unit (202) that sequentially updates and displays the current detection content of a monitoring item selected from a plurality of monitoring items related to the operation state of the construction machine, a memory (206) that registers the monitoring item for which the signal for instructing the registration is input by the input unit (201), and a controller (203) that causes the display unit (202) to display the current detection content of the registered monitoring item when there is the monitoring item registered in the memory (206).

Claims

1. An operation vehicle monitoring device, including a display unit configured to display a standard screen that displays an operation state of an operation vehicle, and a service menu display screen for performing a maintenance and setting of the operation vehicle, and the service menu display screen being transitioned from the standard screen by a predetermined operation and displayed, where the service menu display screen displays a plurality of menus related to the maintenance and setting of the operation vehicle, a monitoring item selection screen is shifted and displayed in which it is possible to select a plurality of monitoring items corresponding to a selected menu in case where one of the plurality of menus is selected, and the display unit displays a monitoring item selected from the plurality of monitoring items related to the operation state of the operation vehicle, comprising:

an input unit configured to input a signal that instructs a registration of the selected monitoring item;

a storage unit configured to register the monitoring item according to the input signal; and

a display control unit configured to force the display unit to display the monitoring item registered in the storage unit.

2. The operation vehicle monitoring device according to claim 1, wherein the display unit displays a plurality of tabs that can be switched to each other in a screen displaying the plurality of monitoring items, and one of the plurality of tabs corresponds to a screen displaying a list of monitoring items registered in the storage unit.

3. The operation vehicle monitoring device according to claim 1, further comprising

a signal detection unit configured to detect a key-on signal and a key-off signal generated when a key switch of the operation vehicle is turned on and off, respectively, wherein,

in a case where the signal detection unit detects the key-on signal after detecting the key-off signal, the display control unit causes the display unit to display a current detection content of the monitoring items registered in the storage unit.

4. The operation vehicle monitoring device according to claim 3, wherein, in a case where the signal detection unit detects the key-on signal in a predetermined time after detecting the key-off signal, the display control unit forces the display unit to display the current detection content of the monitoring items registered in the storage unit.

5. The operation vehicle monitoring device according to claim 1, wherein the display unit displays the current detection content of the monitoring items and displays, by a graphic or a character, at least part of a plurality of gauges displaying a plurality of state quantity levels of the operation vehicle upon a normal operation of the operation vehicle.

6. The operation vehicle monitoring device according to claim 1, wherein the monitoring item relates to a hydraulic pump and/or an engine mounted on the operation vehicle.
