Abstract:
1. A device control system, comprising: a device controller which is to be connected to a load device via a signal line and is configured to output to the signal line a first control signal for controlling the load device; a wireless master which is connected to the device controller via the signal line and is configured to perform wired communication with the device controller; and a wireless slave configured to perform wireless communication with the wireless master, wherein: the wireless slave is configured to send to the wireless master a second control signal indicative of an intended state of the load device; the wireless master is configured to, when receiving the second control signal from the wireless slave, send the second control signal to the device controller; the device controller is configured to, when receiving the second control signal from the wireless master, output to the signal line the first control signal corresponding to the second control signal; the device controller is configured to, when receiving a state change notice indicative of a current state of the load device after sending the first control signal corresponding to the second control signal, send the received state change notice to the wireless master; the device controller is configured to output a state check signal to the signal line at a predetermined timing; the device controller is configured to, when receiving a third control signal indicative of an intended state of the load device via the signal line after sending the state check signal, output the first control signal corresponding to the third control signal to the signal line; the device controller is configured to, when receiving the state change notice after sending the first control signal corresponding to the third control signal, send the received state change notice to the wireless master; and the wireless master is configured to, when receiving the state change notice from the device controller, send the received state change notice to the wireless slave.
