To provide a communication method for a mover operation system which can dispense with the work of wiring a communication line, the replacement work required by abrasion, etc.
Carry trucks 4A-4C travel on a guide rail 3, receiving the power from power supply lines through a pickup coil. An operation controller 6 which performs communication with the carrier trucks 4A-4C is installed at the position separate from the guide rail. The operation controller 6 superposes a communication signal on the wave of the power flowing to a power supply line 11 through a transmission antenna 22 on the ground side. The signal where the communication signal from this operation controller 6 is superposed is received with the reception antenna 15 of the carry truck. On the other hand, the carry trucks 4A-4C superpose communication signals on the waves of the power flowing to the power supply line 11 through the transmission antenna 23. The signals where the communication signals from the carry trucks 4A-4C are received with an reception antenna 23 on ground side.
