A remote control system to remote control a plurality of moving machines and to cause interaction based on communication among the moving machines without complexity and an increase in electric power consumption. A transmitting device of data containing operation control information and communication control information, and a device which specifies a transmission timing from the data from another transmitter and a transmission schedule, are provided. A controlling device controls operation on the basis of operation control information and transmission to another moving machine on the basis of communication control information at the time of receipt from the transmitter and executes a predetermined process at the time of receipt from another moving machine. The controlling device specifies a self transmission timing from the data from the transmitter and the transmission schedule, and transmits it. A transmission schedule stipulates respective transmission timings such that they do not overlap.
