A management system of the mining machine includes a position information detector which detects position information about the mining machine; an operation information detector detecting operation information about the mining machine; and a first evaluation device evaluating the operation information based on the position information and the operation information. A route in a mine includes nodes disposed at a predetermined distance and links connecting between the adjacent nodes, and includes route information including a specific section in which a difference in a gradient between the adjacent links is a predetermined value or less, a difference in an orientation between the adjacent links is a predetermined value or less, and no intersection exists between the adjacent links. The first evaluation device evaluates the operation information in the specific section of the route.

Management system and management method for mining machine

A mining machine management system includes: a position information detection unit detecting position information related to a position of a mining machine; and a determination unit determining whether a second route corresponding to a position information group obtained from a plurality of pieces of the position information detected when the mining machine is in operation is identical to a first route that is a route taken by the mining machine departing a predetermined first position, passing a second position at which a load is loaded, and moving to a third position at which the load is removed, based on at least route information of the first route and the position information group, the route information including a plurality of nodes present at every predetermined distance of the first route and a link connecting the nodes adjacent to each other.

Mining machine management system and mining machine management method

A mining machine management system includes: a position information detection unit which is mounted in a mining machine loading a load in a mine and transporting the load and detects position information related to a position of the mining machine; and a region specification unit which corrects a representative position of a discharging station at which the load is removed, based on position information of a position at which the load is removed from the mining machine within a predetermined range centered around the representative position, from among the position information detected by the position information detection unit.

A mining machine management system includes: a position information detector which is mounted on a mining machine enabled to travel on a route in a mine and detects position information about the mining machine; an operation information detector which is mounted on the mining machine and detects operation information about the mining machine; and a processor which obtains accumulated data of the operation information in a predetermined section of the route based on the position information and the operation information.

Management system and management method of mining machine

A mining machine management system includes: a route information generation unit generating route information based on position information obtained when a mining machine in operation travels along a route departing from a predetermined first position, passing a second position where a load is loaded, and moving to a third position where the load is removed, the route information including nodes of the route and a link connecting the nodes; and a route analysis unit determining a section having the links within the route information to be a specific section where a slope difference between the links falls within a value, an orientation difference between the links falls within a value, and there is no intersection between the links.

A mining machine management system includes: a position information detection unit detecting position information related to a position of a mining machine; and a determination unit determining a second route corresponding to a plurality of pieces of the position information is identical to a first route based on at least whether a position of each node corresponds with the position information, the node being a piece of information related to a position of the first route that is a route taken by the mining machine departing a predetermined first position, passing a second position at which a load is loaded, and moving to a third position at which the load is removed.

In a management system of the mining machine, a management device collects operation information about the dump truck via a management-side wireless communication device. Routes along which the dump truck travels are identified based on position information, included in the operation information about the dump truck, about at least four locations included in a route along which the dump truck moves to a location where the dump truck unloads a load, to a location where the dump truck loads a load, and to a location where the dump truck unloads the load again.

To predict the service life of a construction machine more accurately, and to make it possible to draw up an appropriate overhaul implementation plan at an early stage. A first service life prediction unitpredicts the service lives of main components such as an engine and the like, based upon their actual wear states. And a second service life prediction unitpredicts the service lives of the same components, based upon their cumulative load amounts. An order setting unitselects the ones of these two predicted service lives which are the shorter, and sets a priority order for overhaul in order of shortness of predicted service life. An overhaul schedule table generation unitcreates a schedule table Dbased upon this priority order. The contents of this schedule table Dare decided upon by a judgment unit, and, if necessary, are corrected by a correction unit. And a plan creation unitcreates an overhaul implementation plan document Dand the like, based upon the corrected schedule table D. The result of the overhaul task and the present states of components are tested, and these test results are reflected by the service life prediction unitsand
