  • Publication number: 20230165487
    Abstract: The abnormal data processing system is provided with: a storage unit for holding a multiple-subject DB in which data on multiple subjects are accumulated and individual-subject DB in which data on individual subjects are accumulated; an individual-subject DB divergence-degree calculation unit for calculating an individual-subject DB divergence degree which is the degree of divergence of the new data from the individual-subject DB; a multiple-subject DB divergence degree calculation unit for calculating a multiple-subject DB divergence degree which is the degree of divergence of the new data from the multiple-subject DB; and a composite divergence degree calculation unit for determining a composite divergence by compositing the individual-subject DB divergence degree and the multiple-subject DB divergence degree using the number of data instances in the individual-subject DB. The abnormal data processing system determines whether or not the new data is abnormal on the basis of the composite divergence degree.

  • Patent number: 11320279
    Abstract: A travel route management system includes an area setting unit that sets a work site to an outer peripheral area SA and an area CA to be worked on an inner side of the outer peripheral area SA, and a route element selecting unit that sequentially selects a next travel route element to be traveled on next, from among multiple mutually-parallel travel route elements, the travel route elements constituting a travel route that covers the area CA to be worked. The route element selecting unit selects a U-turn travel route for moving from a travel route element serving as a movement origin to a next travel route element serving as a movement destination, the selection being made on the basis of an interval between the movement origin and the movement destination.

  • Patent number: 11300976
    Abstract: A work vehicle automatic traveling system includes a route element selecting unit that, on the basis of state information, sequentially selects a next travel route element on which a work vehicle is to travel next, from a travel route element set and a circling route element set. The route element selecting unit includes a cooperative route element selection rule, which is employed when a plurality of work vehicles carry out work travel cooperatively in an area CA to be worked, and an independent route element selection rule, which is employed when a single independent work vehicle among the work vehicles carries out work travel independently in the area CA to be worked. Also described is selecting the next travel route element based on the independent route element selection rule.
