Abstract

Operation of self-propelled mining equipment in the field can be accurately recognized at a remote position of the equipment. A management center for controlling a dump truck receives signal from sensors in order to show detection data for the working status of the operation instruments and warning indication data based upon the detection data. The warning indication data and the detection data for the working status of the operation instruments are displayed on the same display. Alternatively, in place of the detection data for working status of the operation instruments, related information from a data base concerning the record of maintenance previously conducted may be displayed, or a graph of the detection data for the working status of an operation instrument of another dump truck which is operating in the same working field may be displayed.

Claims

1. An operation management device for self-propelling mining equipment, the operation management device comprising:

a wireless communication receiver configured to receive an output signal from a sensor for detecting an operation status of a component part of the self-propelling mining equipment;

a signal processor connected to the wireless communication receiver, and which is programmed to produce a management image; and

a display which is connected to the signal processor,

wherein the signal processor is further programmed to execute;

a graph creating section to create, as a graph indicating a temporal transition of the output signal, first instrument operating status detection data from the output signal,

a warning level judging section to judge whether or not a value of the output signal is respectively out of one or more predetermined standard levels,

a warning indication creating section to create one or more warning indications for the respective predetermined standard levels at one or more timings when the value of the output signal is judged to be out of the respective predetermined standard levels, and

an image creating section to create the management image by using the first instrument operating status detection data, the warning indications, and second instrument operating status detection data that is instrument operating status detection data of other self-propelling mining equipment performing a same work as the self-propelling mining equipment in a mining field and is held in a database connected to the operation management device, and to output the management image on the display, and

wherein the image creating section creates the management image to display the first instrument operating status detection data and the second instrument operating status detection data side by side on a same time axis in a predetermined region for displaying instrument operating status detection data and to display the one or more warning indications at positions on the same time axis, which correspond to the one or more timings when the value of the output signal is judged to be out of the respective predetermined standard levels, in a predetermined region for displaying warning indications.

2. The operation management device according to claim 1, wherein, upon receiving an instruction via a predetermined shifting icon indication region in the management image in a state where the management image is displayed, the image creating section creates, in the predetermined region for displaying instrument operating status detection data, a second management image in which related information related to the first instrument operating status detection data is displayed, and outputs the second management image on the display.

3. The operation management device according to claim 2, wherein the related information contains a maintenance history of the self-propelling mining equipment.
