A wireless communication system allows the movement of a carriage or an automated conveyance vehicle to which a plurality of slave wireless device and a plurality of appliances are provided. A master control unit of a master wireless device uses a master communication unit to transmit a cut-off request signal to a slave wireless device deviating from a communication-target region. If a slave communication unit receives the cut-off request signal, a slave control unit of the slave wireless device cuts off a wireless connection.
