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. Operation management device comprises an self-propelling mining equipment which is working in a mining field, and a management center for performing to control the operation of the self-propelling mining equipment, the self-propelling mining equipment being provided plural number of sensors for detecting the operation of component parts, the detection data being transmitted by means of a communication member to the management center,

characterized in that the device further comprising:

the management center having a signal processing member to perform signal processing for preparing detection data for working status of respective operation instruments based upon data transmitted from the self-propelling mining equipment to be displayed in the form of chronological pattern, and an image display member adapted to indicate graph of detection data for working status of the operation instruments;

one or more warning levels being set to output signals from the sensors, and a warning indication region for showing warning indication data at respective warning levels, and the image display member together with the detection data for working status of the operation instruments or in place of the detection data for working status of the operation instruments; and

the management center being connected an information storage member for storing related information as to operation instrument provided with the sensor, and the related information being read out from the information storage member to display the related data together with the warning indication data on the image display member.

2. Operation management device for mine site of self-propelling mining equipment according to claim 1, wherein the image display member adapted to show plural kinds of the related information, and the image display member is provided a shift icon designated region for displaying one of the related information.

3. Operation management device for mine site of self-propelling mining equipment according to claim 1, the related information contains maintenance history of the component part.

4. Operation management device for mine site of self-propelling mining equipment according to claim 1, wherein the image display member being adapted to instrument operation status detection data for the component part of the self-propelling mining equipment, and the related information being detection data for working status of an operation instrument of other self-propelling mining equipment than the detection data of the self-propelling mining equipment shown on the image display member.
