Abstract
In a vehicle-oriented system (1) for providing information to a vehicle (5) side by using an information providing area (11) provided on a plane where a vehicle (5) moves, a magnetic distribution indicating the information by a plurality of N-pole magnetic markers (10N) is formed in the information providing area (11), and a sign (100) for identifying a position and orientation of the information providing area (11) is provided in the information providing area (11). Therefore, information can be provided by a magnetic method irrespective of a forwarding direction of the vehicle (5).
Claims19
A vehicle-oriented system comprising:
- a plurality of information providing areas provided on a plane where a vehicle moves, for providing information to the vehicle,
- wherein the plurality of information providing areas are two-dimensionally arranged to form grid points on the plane,
- wherein each of the plurality of information providing areas is a two-dimensional area forming a rectangular shape where a plurality of piece-like magnetic markers are two-dimensionally arrayed,
- wherein in each of the plurality of information providing areas, a magnetic distribution indicating the information is formed by a distribution pattern of the plurality of piece-like magnetic markers, and a sign to identify a position and orientation of corresponding information providing area is provided, individually from the plurality of piece-like magnetic markers.
A vehicle-oriented system comprising:
- an information providing area provided on a plane where a vehicle moves, for providing information to the vehicle,
- wherein in the information providing area, a magnetic distribution indicating the information is formed, and a sign to identify a position and orientation of the information providing area is provided,
- wherein the magnetic distribution is formed by at least one piece-like magnetic marker arranged in the information providing area,
- wherein the sign is a magnetic sign based on magnetic polarity of the at least one piece-like magnetic marker to be detected by the vehicle,
- wherein the information providing area is a two-dimensional area forming a rectangular shape where the at least one piece-like magnetic marker is two-dimensionally arrayed, and
- wherein the sign is formed of three magnetic markers arranged at three locations of four locations forming corner portions of the two-dimensional area in the rectangular shape.
An information reading method comprising:
- obtaining a magnetic distribution in at least one of a plurality of information providing areas when a vehicle passes over the at least one of a plurality of information providing areas, the plurality of information providing areas being provided on a plane where the vehicle moves, for providing information to the vehicle, and in each of the plurality of information providing areas, the magnetic distribution indicating the information being formed by a distribution pattern of a plurality of piece-like magnetic markers;
- identifying orientation of the at least one of the plurality of information providing areas by detecting a sign, the sign being provided to identify a position and orientation of corresponding information providing area, individually from the plurality of piece-like magnetic markers;
- and
- identifying and reading the information indicated by the obtained magnetic distribution in accordance with the identified orientation of the corresponding information providing area,
- wherein the plurality of information providing areas are two-dimensionally arranged to form grid points on the plane, and
- wherein each of the plurality of information providing areas is a two-dimensional area forming a rectangular shape where the plurality of piece-like magnetic markers are two-dimensionally arrayed.
