Communication method, transport system, and communication device

A communication method of a transport system, the transport system including a plurality of transport carriages, each transporting a transported object, and a plurality of communication devices connected one-to-one with corresponding ones of a plurality of equipment onto which the transported objects are loaded, the plurality of communication devices being communicably connected to each other in advance, the communication method comprising:

• (a) transmitting, from a specific transport carriage among the plurality of transport carriages to the plurality of communication devices, a first signal having a specific communication device among the plurality of communication devices as a final transmission destination;
• and
• (b) receiving, in the specific communication device, the first signal from the specific transport carriage through a communication channel that passes through at least one other communication device among the plurality of communication devices;
• wherein
• the first signal is a signal communicated for the specific transport carriage to transfer the transported object to and from a specific one of the equipment which is connected one-to-one with the specific communication device.
