The present invention is to provide an IR transmission system of an ETCS which is capable of remotely controlling operation of an LED which forms an antenna, is easily designed with lost costs of design and is capable of increasing the operation reliability and use efficiency. The present invention provides an IR transmission system of an ETCS which includes: an antenna for communicating with IR; an antenna driving switching unit for driving the antenna after being turned on; an IR communication unit for transmitting data signal and remote control signal; a conversion unit for receiving the data signal, converting the signal into a converted data signal to be suitable for IR communication and outputting the converted data signal; a buffer power supply voltage control unit which is remotely controlled by the IR communication unit for outputting a control signal; and a buffer for receiving the converted data signal and control signal, outputting an output signal corresponding to the signals to the antenna driving switching unit and controlling operation of the antenna driving switching unit. |
