Abstract
A rail environment monitoring device using a traveling vehicle, the rail environment monitoring device includes a sensing unit connected to a traveling vehicle transporting a conveyed object along a travel rail, the sensing unit configured to sense a travel rail positioned on a path of travel of the traveling vehicle and a travel rail peripheral portion, and a map production unit configured to generate a map for the travel rail or the travel rail peripheral portion using data acquired by the sensing unit according to the path of travel of the traveling vehicle.
Claims18
A rail environment monitoring device using a traveling vehicle, the rail environment monitoring device comprising:
- at least one sensor connected to a traveling vehicle transporting a conveyed object along a travel rail, the at least one sensor configured to sense the travel rail positioned on a path of travel of the traveling vehicle and a travel rail peripheral portion;
- and
- a processor configured to generate a map for the travel rail or the travel rail peripheral portion using data acquired by the at least one sensor according to the path of travel of the traveling vehicle;
- and
- a control unit configured to periodically collect, using the at least one sensor, rail environment information, and to control the path of travel of the traveling vehicle or transmit the rail environment information to the processor to resolve an abnormality occurring on the path of travel of the traveling vehicle.
A logistics transportation apparatus comprising:
- a traveling vehicle configured to transport a conveyed object along a travel rail;
- at least one sensor connected to the traveling vehicle, the at least one sensor including a lidar sensor configured to sense a travel rail positioned on a path of travel of the traveling vehicle and a travel rail peripheral portion, and an image sensor connected to the traveling vehicle in a position adjacent to the travel rail, the image sensor configured to image the travel rail and the travel rail peripheral portion;
- a control unit connected to the traveling vehicle, the control unit configured to periodically collect rail environment information using the sensor while the traveling vehicle is traveling, to control the path of travel of the traveling vehicle or transmit the collected rail environment information to a processor to resolve an abnormality occurring on the path of travel of the traveling vehicle;
- and
- the processor connected to the traveling vehicle, the processor configured to generate a map for the travel rail or the travel rail peripheral portion using the rail environment information collected according to the path of travel of the traveling vehicle.
A rail environment monitoring method of a traveling vehicle, the rail environment monitoring method comprising:
- a sensing operation of sensing, by the traveling vehicle, a travel rail state through at least one sensor disposed in the traveling vehicle;
- and
- a map production operation of generating, based on the travel rail state acquired in the sensing operation, a map for the travel rail or a travel rail peripheral portion,
- wherein the sensing operation of sensing the travel rail state includes at least one of:
- sensing, using the at least one sensor, presence or absence of particles on the travel rail including a path of travel of the traveling vehicle;
- imaging a region in which particles are sensed using an image sensor included in the at least one sensor;
- and
- imaging a tag attached to the travel rail using the image sensor included in the at least one sensor.
