Abstract:
A remote control module for a computer, which creates an order to control a shut down and a start of a computer system by analyzing a DTMF (dual tone multi frequency) signal received through a telephone line, the remote control module comprising:a telephone line interface section for outputting the DTMF signal received through the telephone line by converting the DTMF signal into a predetermined voltage level; an amplifying section for amplifying and filtering the signal transmitted from the telephone line interface section; an A/D converter for converting an analog signal of the amplifying section into a digital signal; a control section for extracting a computer remote control order from the DTMF signal by analyzing the digital signal transmitted from the A/D converter, and for creating a message based on the computer remote control order; a first relay controlled by the control section so as to output a reset signal to a reset terminal of a power circuit of the computer system; a second relay controlled by the control section so as to output an power on/off signal to a power terminal of the power circuit of the computer system; and a serial transmission interface section for receiving the message from the control section and transmitting the message to the computer system by converting the message in match with a serial transmission interface standard.
