In a control method, a controller obtains equipment specifying information that specifies an equipment to which a transportable object is to be delivered, and a transport carriage obtains carriage position information indicating the position of the transport carriage. Any one of the transport carriage, a specific communication device, and the controller calculates the distance between the transport carriage and the specific communication device based on delivery position information indicating the position of a specific equipment and the carriage position information, and determines whether the distance is not more than a predetermined distance. When the distance is not more than the predetermined distance, one of the transport carriage and the specific communication device transmits, wirelessly to the surroundings, a trigger signal to start wireless communication between the transport carriage and the specific equipment, and performs wireless communication to deliver the transportable object between the transport carriage and the specific equipment.

Control method, transport system, and communication device

A communication method of a transport system including of transport carriages each transporting a transported object, and communication devices connected one-to-one with loading ports onto which the transported objects are loaded. The communication devices are communicably connected to each other in advance. The communication method includes transmitting, from a specific transport carriage to the communication devices, a first signal having a specific communication as a final transmission destination, and receiving, in the specific communication device, the first signal from the specific transport carriage through a communication channel that passes through another communication device. The first signal is a signal communicated for the specific transport carriage to transfer the transported object to and from a specific loading port connected one-to-one with the specific communication device.

A method of recognizing a specific image includes detecting image features from the specific image and storing in a memory each of detected relevant image features, detecting relevant image features from an input image and selecting from the memory a portion corresponding to each of the detected relevant image features, generating a restoration image using portions selected in the selecting, and determining whether the generated restoration image matches with the input image by a matching process and recognizing that, when it is determined that the restoration image matches with the input image, the input image is the specific image.

An elevation conveyorincludes a turntableand a roller conveyor. The roller conveyoris supported onto the turntable. A turntable controllerturns the turntableso that the roller conveyormatches with a carrying direction of a conveyor rail for receiving or delivering a load and then drives the conveyor rail and the roller conveyorto receive or deliver an FOUP. An elevation conveyoris held in a cableinstalled in an elevation spacethrough a coupling memberof a cableveyor, and can freely elevate and stop at a portinstalled on each floor while being interlocked with motion of the cableveyorcaused by reciprocating circulation of the cableveyorin a vertical direction by an elevation conveyor controller
