Provided is a data transmission system for a work machine, including: a processing definition receiving unit configured to receive processing definition information indicating contents of processing of data collected from the work machine; a processing unit configured to determine a data format to be processed, based on the received processing definition information, and process the data collected from the work machine based on the determined data format; and a transmission unit configured to transmit the processed data to an external device.

Data transmission system, work machine, and data transmission method for work machine

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.

A transporter vehicle includes: a vehicle; a vessel that is provided in the vehicle; a traveling state detection device that detects a traveling state of the vehicle; an object detection device that detects an object in front of the vehicle; and a collision determination unit that determines a possibility of collision with the object based on a loading state of a load of the vessel, a detection result of the traveling state detection device, and a detection result of the object detection device.

Transporter vehicle and transporter vehicle control method

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 bush () which relatively-rotatably supports a journal shaft () around its central axis by housing the journal shaft () in a formed bearing hole (), the bushincludes an oil supply groove () formed spirally to supply lube oil to an inner surface of the bearing hole () which contacts to the journal shaft () when the journal shaft relatively rotates. A ratio of an area of the oil supply groove () to the inner surface area of the bearing hole () is equal to or less than 30%. A product of a distance in the central axis direction and a distance in the circumferential direction of the journal shaft () between the oil supply groove () in next to each other on the inner surface of the bearing hole () is within 50 to 300 mmrange.

Bearing device

Insulative viscous fluid or gel material having low hardness is used for at least a first electricity insulating layer as an insulating layer of a static electricity chuck. Since a holding surface of the first electricity insulating layer is deformed in accordance with a back surface shape of a wafer, a substantially entire surface of the holding surface comes into intimate contact with the wafer uniformly. An exposing surface of the electricity insulating layer may be coated with a second electricity insulating layer having corrosion resistance. With this structure, adhesion between the back surface of the wafer and the static electricity chuck apparatus is enhanced, which reduces the contact thermal resistance, and it is possible to obtain a static electricity chuck apparatus which is capable of controlling temperature of a surface of the wafer with high precision and has high plasma resistance and durability.
