Abstract: Remote control of a moving object such as an overhead crane is provided with both safety and responsiveness/workability. A display is attached to a hoist of an overhead crane, and wall display units are attached to walls of the building. The crane can be operated in a plurality of operation modes. A pre-movement notice mode is a safe operation mode in which a direction of movement is displayed on the display units when movement is indicated using a direction button on a remote controller, and movement starts after a predetermined amount of time has elapsed or some type of movement instruction is given. An immediate movement mode is an operation mode having excellent responsiveness/workability in which movement is started immediately without a prior notice. The remote controller is provided with a mode switching button for switching between operation modes, thereby enabling switching between a plurality of modes.

Abstract: A camera and a laser radar are attached to the hoist of an overhead crane. Image data and three-dimensional point clouds are acquired during operation and accumulated as operation result data. An information processing apparatus displays the crane's movement trajectory on the terminal and predicts maintenance timing based on operation result data, evaluates a degree of danger and detects an occurrence of accident based on a positional relationship between the crane and an operator, performs optimization of a movement path, a transport sequence of multiple suspended loads, a layout in the facility, and the like, and performs post-operation diagnosis for the degree of danger and operation efficiency of the crane. In addition, the crane is used to scan the inside of the facility to detect abnormalities such as fires and suspicious persons after the work hours of the facility. These treatments can improve the usefulness of the crane.
