Abstract

The present invention provides a method for displaying an operation status of a construction machine by sensing operating information of the construction machine by means of a coolant water sensor and the like, sending the operating information to a control computer while the control computer receives the operating information which has been sent from the construction machine, determines whether the construction machine is in operation or not based on the received operating information, and displays the result of judgment on a monitor screen, so that the current operation status of the construction machine can be known easily.

Claims

1. A method for displaying an operation status of a construction machine comprising the steps of:

transmitting operating information obtained from the construction machine to a control device that can communicate with the construction machine;

having said control device receive said operating information;

having said control device determine whether the construction machine is in operation or not based on said operating information; and

displaying a result determined by said control device on a monitor screen of said control device.

2. The method according to claim 1 wherein said operating information includes location information of the construction machine.

3. The method according to claim 2 wherein said location information is displayed on the monitor screen together with the result.

4. The method according to claim 3 wherein a map of an area including a place where the construction machine is located is displayed on the monitor screen, while the result being superimposed on a position which corresponds to the location information on the map.

5. The method according to claim 1 further comprising the steps of:

having the control device determine whether it is necessary to provide the construction machine with maintenance service or not based on the operating information and, when it is determined that maintenance service is required, having both required maintenance works and the result determined on whether the construction machine is in operation or not displayed on the monitor screen of said control device.

6. An apparatus for displaying an operation status of a construction machine provided for a control device which can communicate with the construction machine, comprising;

receiver that receives operating information of the construction machine transmitted from the construction machine;

operation status judging means which determines whether the construction machine is in operation or not based on said operating information; and

operation status display means that displays a result of judgment determined by said operation status judging means on a monitor screen.

7. The apparatus according to claim 6 wherein said operating information includes location information of the construction machine and said operation status display means has location display means which displays the location information together with the result of judgment on the monitor screen.

8. The apparatus according to claim 7 wherein said operation status display means has map display means displaying on the monitor screen a map of an area including a place where the construction machine is located, and displaying on the map the result of judgment superimposed on a position which corresponds to the location information.

9. The apparatus according to claim 6, further comprising:

maintenance service judging means which is provided on the control device and determines whether it is necessary to provide the construction machine with maintenance service or not based on the operating information; and

maintenance work displaying means that displays both required maintenance work and the result of judgment by the operation status judging means on the monitor screen, when it is determined that the maintenance service is required.

10. A construction machine comprising:

a sensor which senses operating information of the construction machine; and

transmitting means capable of sending the operating information sensed by the sensor to a control device which can communicate with said construction machine, the control device determining whether the construction machine is in operation or not based on said operating information.

11. A method for displaying an operation status of a construction machine on a monitor screen of a control computer which can communicate with said construction machine, characterized in that

the construction machine senses operating information thereof and sends the sensed operating information to the control computer;

and

the control computer receives the operating information sent from the construction machine, determines whether the construction machine is in operation or not based on the received operating information, and displays a result of judgment determined by the control computer on a monitor screen.
