Abstract

The mobile body control system includes: an acquisition unit that acquires information on the entry source and information on the destination of the first and second mobile bodies that enter the elevator car; and a determination unit that determines whether or not the first and second mobile bodies pass each other based on the information on the entry source and the information on the destination of the mobile body. When the determination unit determines that the passing of the first and second mobile bodies occurs, at least one of the first and second mobile bodies changes the operation plan.

First claim

What is claimed is:

1 . A mobile body control system comprising:
an acquisition unit that acquires information on an entry source and information on a destination of a first mobile body and a second mobile body entering an elevator car having a plurality of doors; and a determination unit that determines whether the first mobile body and the second mobile body pass each other, based on the information on the entry source and the information on the destination of the mobile bodies, the information on the entry source includes information indicating a floor number of the entry source and identification information of an entry door, and the information on the destination includes information indicating a floor number of the destination and identification information of an exit door, and whether the first mobile body entering from a first door and exiting from a second door and the second mobile body entering and exiting from only one of the first and the second doors pass each other, when the determination unit determines that the first mobile body entering from the first door and exiting from the second door and the second mobile body entering and exiting from only one of the first and the second doors pass each other, the determination unit determines whether a first graph on xy coordinates represented by Equation 1 below and a second graph on xy coordinates represented by Equation 2 below have an intersection point, and when the first graph and the second graph have the intersection point, the determination unit determines that the first mobile body and the second mobile body pass each other,

b is a floor number of a destination of the first mobile body,
c is a floor number of an entry source of the second mobile body,
d is a floor number of a destination of the second mobile body,
m 1 and m 2 are different real numbers,

when the second mobile body enters and exits from the second door, m is m 2 ,
when m is a larger one of m 1 and m 2 , k is a positive real number,
when m is a smaller one of m 1 and m 2 , k is a negative real number,
k satisfies the following Equation 3, and

f is a total number of floors on which the elevator car is able to move,
wherein when the determination unit determines that the first mobile body and the second mobile body pass each other, a control unit of at least one of the first mobile body and the second mobile body changes an operation plan.

2 . The mobile body control system according to claim 1 , wherein when the determination unit determines
