Abstract
A power feeder includes a feed line extending along a travel path for movable bodies to power to the movable bodies, a power supply device connected to the feed line to supply power to the feed line, and a control system that controls the power supply device. The control system includes a count obtainer that obtains count information indicating the number of movable bodies in a power feed area in which the feed line is disposed in the travel path, and a controller that performs, based on the count information, variable power control to reduce power from the power supply device to the feed line in response to a decrease in the number of movable bodies in the power feed area and to increase power from the power supply device to the feed line in response to an increase in the number of movable bodies in the power feed area.
Claims6
A power feeder, comprising:
- at least one feed line extending along a travel path for a plurality of movable bodies to feed power to the plurality of movable bodies;
- at least one power supply device connected to the at least one feed line to supply power to the at least one feed line;
- and
- at least one control system configured to control the at least one power supply device, the at least one control system comprising:
- a count obtainer configured to obtain count information indicating a number of movable bodies in at least one power feed area, wherein the at least one power feed area is an area in which the at least one feed line is disposed in the travel path, and
- a controller configured to perform, based on the count information, variable power control to reduce power supplied from the at least one power supply device to the at least one feed line in response to a decrease in the number of movable bodies in the at least one power feed area and to increase power supplied from the at least one power supply device to the at least one feed line in response to an increase in the number of movable bodies in the at least one power feed area.
