Abstract

The goal is to enable the autonomous mobile unit inside the elevator car to determine when it has arrived at its destination floor and is ready to disembark, without the need to install equipment such as routers or 2D barcodes, thereby preventing problems when the autonomous mobile unit is using the elevator. [Solution] The control device includes a calculation unit that calculates the distance traveled from the departure floor to the destination floor when it receives a movement request from an autonomous mobile vehicle, and a door control unit that opens the doors of the elevator car when it arrives at the departure floor. After opening the doors, the first communication unit sends a boarding readiness notification and the distance traveled to the autonomous mobile vehicle that made the movement request, and after the elevator car arrives at the destination floor and the doors are opened, it sends a disembarking readiness notification to the autonomous mobile vehicle.
