Abstract:
A control system includes: a first transmitter; a second transmitter; and a reception device. The first transmitter includes a transmission unit configured to transmit radio waves to the reception device, the second transmitter includes a transmission unit configured to transmit radio waves to the reception device; and the reception device includes: a reception unit configured to receive radio waves transmitted from the first transmitter and the second transmitter; an identification unit configured to identify whether a transmission source of the radio waves is the first transmitter or is the second transmitter based on the radio waves received by the reception unit; a measurement unit configured to measure the distance between the device and the transmission source of the radio waves identified by the identification unit; and a control unit configured to perform a first control that sets a limitation on the device or a second control that does not set a limitation on the device based on the distance, measured by the measurement unit, between the device and the transmission source of the radio waves.
