Method and system for controlling and switching power source associated with electrical devices

A system for controlling and switching a power source for switching input power supplied to a plurality of loads, comprising:

• a plurality of switching sets for controlling the plurality of loads;
• a telephone line connecting unit connected to the switching sets and to a telephone, by which a state of the switching sets is monitored and controlled through the telephone, and results of the monitoring and controlling are outputted to a user as a voice message,
• wherein the telephone line connecting unit comprises,
• a central processing unit (CPU) interfaced with a switching set controller, for controlling an output operation of a voice message according to an input command applied via a telephone line,
• a switching set controller interfaced with the CPU, for outputting a control signal to turn on/off one of the loads,
• a transmission/receiving unit for transmitting the output control signal of the switching set controller to one of the loads, and supplying the received response signal to one of the switching sets,
• a voice message outputter for outputting at least one voice message from a plurality of pre-stored voice messages under the control of the CPU,
• a voice signal processor for performing signal processing to transmit the voice messages of the voice message outputter via the telephone line upon detecting a tone signal from the user, and
• a dial signal detector for detecting a dial signal received via the telephone line,
• wherein the voice message outputter includes,
• a short phoneme processor for outputting phonemic information regarding a short phoneme portion of the voice messages under the control of the CPU,
• a long phoneme processor for outputting phonemic information regarding a long phoneme portion of the voice messages under the control of the CPU,
• a voice signal controller for outputting voice data corresponding to the phonemic information output from the short and long phoneme processors,
• a voice oscillator for ouputting an address corresponding to a predetermined oscillating frequency to output a voice to said voice signal controller, and
• a voice signal mixer for mixing the voice corresponding to the voice address to a voice signal of an analog form.
