  • Publication number: 20230394893
    Abstract: A management system includes a working vehicle and a server. The working vehicle includes a working device, a vehicle body capable of traveling by either automatic steering based on a reference line or manual steering, a position detector to detect a position of the vehicle body, a first memory to store, in a case where the vehicle body is automatically steered, correspondence information in which setting information of the working vehicle and position information of the vehicle body are associated with each other, and a first communicator to transmit the correspondence information stored in the first memory to the server. The server includes a second communicator to receive the correspondence information transmitted by the first communicator, and a second memory to store the correspondence information received by the second communicator.

  • Publication number: 20230389461
    Abstract: A management system includes a working vehicle and a server. The working vehicle includes a setting switch to enable or disable a setting mode of performing setting before a start of automatic steering, a first memory to store correspondence information in which setting mode information indicating whether the setting mode is enabled or disabled, time information measured by a timer, and position information of a vehicle body are associated with each other, and a first communicator to transmit the correspondence information stored in the first memory to the server. The server includes a second communicator to receive the correspondence information transmitted by the first communicator, a second memory to store the correspondence information received by the second communicator, and an information manager to manage the correspondence information stored in the second memory, based on the setting mode information.

  • Patent number: 11589508
    Abstract: A field map generating system includes: a crop data obtaining unit that obtains crop data over time; a position information obtaining unit that obtains position information, indicating a harvesting position of the crop, over time; polygon constructing units that construct a polygon on the basis of a work width and speed of a harvester, for each piece of crop data obtained by the crop data obtaining unit; data assigning units that assign crop data or crop information based on the crop data to the constructed polygons; a position information assigning unit that assigns position information to the constructed polygons; and field map generating units that generate a field polygon map, which is an aggregate of the polygons, by aggregating the polygons.

  • Patent number: 5862311
    Abstract: An inter-equipment data link system performs a data link between double equipments of an A data transmission equipment and a B data transmission equipment. In the system, a monitor output of the A data transmission equipment is supplied to the B data transmission equipment. The monitor output of the B data transmission equipment is also supplied to the A data transmission equipment. The monitor output of each of the A, B data transmission equipments includes a data frame according to a High Level Data Link Control procedure. Each of the A, B data transmission equipments includes a monitor data input decomposing unit which receives the data frames of the monitor output supplied by the other, extracts a data frame of an information type therefrom, and obtains a data portion included in an information portion in the extracted data frame as a result of decomposition.

  • Patent number: 4139973
    Abstract: A method for fixing a glass sheet in a sash which is to surround the entire peripheral edge of the glass sheet and has a channel defined by a bottom wall and side walls; and the resulting assembly of the sash and the glass sheet fixed therein. The glass sheet is set in the sash, and then fixed elastically in the channel at positions spaced at intervals along the peripheral edge of the glass sheet. Then, an elastic sealing material is filled along the entire peripheral edge of the glass sheet between each of the surfaces of the peripheral edge of the glass sheet and each of the side walls of the channel opposite thereto, leaving an unfilled space at the bottom of the channel. Subsequent hardening of the sealing material affords a substantially fluid-tight seal along the entire peripheral edge of the glass sheet between each of the surfaces of the peripheral edge of the glass sheet and each of the side walls of the channel opposite thereto, and achieves the fixation of the glass sheet in the sash.
