Abstract:
1. A device identification apparatus for transmitting an optical device identification signal for identifying a corresponding device among a plurality of similar such optical transmitting devices to a remote controller that stores and transmits optical code signals to control the devices, the device identification apparatus comprising: a receiving section that receives the optical code signal from the remote controller; a signal decryption section that decrypts the optical code signal and sends a trigger signal to a delay generation section if the code signal is an optical device selecting signal, or returns the device identification apparatus to an initial state if the code signal is not an optical device selecting signal; and a transmitting section for transmitting the optical device identification signal, wherein the delay generation section is between the signal decryption section and the transmitting section, when the delay generation section receives the trigger signal, the delay generation section generates a pre-set delay time specific to the corresponding device and generates a delay time according a signal intensity of the optical code signal, such that the transmitting section transmits the device identification signal after expiration of the delay time, and such that optical signal interference from the similar such optical transmitting devices is avoided.
