Abstract
Radio control over a distance beyond the arriving distance of the conventional radio control and transmission of the continuous instruction signal on the real time are possible. The system provides DTMF signal generation means for modulation of a control signal for controlling a controllable section into DTMF signal, VOIP transmission means for receiving DTMF signal to generate VOIP signal for transmission to VOIP line, VOIP line capable of transmitting VOIP signal, VOIP receiving means for receiving VOIP signal for conversion into DTMF code, DTMF demodulation and retransmission means for conversion of regenerated DTMF signal into a radio control transmission signal and a controllable section for receiving the radio control transmission signal and the signal generated by DTMF signal generation means is driven by DTMF demodulation and retransmission means through VOIP line in order to control the receiving means.
