CONTROL SYSTEM AND RECEPTION DEVICE
First Claim
1. A control system comprising:
- a first transmitter;
a second transmitter; and
a reception device configured to control the device based on radio waves transmitted from the first transmitter and the second transmitter, whereinthe first transmitter comprises a transmission unit configured to transmit radio waves to the reception device,the second transmitter comprises a transmission unit configured to transmit radio waves to the reception device; and
the reception device comprises;
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.
