DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a manual and remote control switching system in which users can optionally turn on/off any load among a plurality of loads in each of different places, and more particularly relates to a switching system which switches a power source being supplied to loads by manipulating either a manual switch or a remote control switch, controls the power source supply to loads, which are set up in a plurality of chambers blocked off from each other, in each of chambers, displays an ON/OFF state and operation possibility of each load, and controls, if necessary, optionally the power source supply to loads.
BACKGROUND ART
Generally, there has been used a manual switch or a remote control switch in switching of a power source. A conventional switch has a drawback that users always operate the manual switches at their original places and carry with a remote controller.
DISCLOSURE OF THE INVENTION
Therefore, to solve the above problem in the conventional device, it is an object of the present invention to provide a switching system which switches optionally a power source of loads set up in the other chamber in respective chambers blocked off from each other as well as performs a switching operation by handling one of a manual switch and a remote control switch.
Another object of the present invention is to provide a switching system which can receive and transmit various control signals, in which a control part and a load part are connected with one signal transmission line.
To accomplish the above objects of the present invention, there is provided a switching system for controlling a power source being supplied to loads, the system comprising: generating an infrared ray signal to control the switching means; receiving means for converting the infrared ray signal supplied from the remote controller into an electric signal; manual switches connected between output terminals of the receiving means and a power supplier; and control signal generating means for controlling the switching means according to the electric signal of the receiving means or an input voltage from the manual switches.
In addition, there is provided a switching system which includes at least two or more loads and switches a power source to be supplied to the loads, the system comprising: switching the power source being supplied to the loads; two or more remote controllers for generating an infrared ray signal to control turning-ON/OFF of the switching means; two or more receiving means for converting the infrared ray signal supplied from the remote controllers into an electric signal; manual switches, connected between output terminals of the receiving means and a power supplier, for providing control signals to respectively control the loads; signal combining means for suppling signals to control the same load among the electric signal from the receiving means or voltages supplied from the manual switches, to control signal generating means; and control signal generating means for controlling the switching means according to signals supplied from the signal combining means.
Further, there is provided a switching system for switching a power source to be supplied to a plurality of loads, the system comprising: source being supplied to respective loads; remote controllers for generating an infrared ray signal to control the switching means; first receiving means for converting the infrared ray signal supplied from the remote controllers into an electric signal; manual switches connected between output terminals of the receiving means and a power supplier; signal transmission means for coding and transmitting the electric signal provided from any one of the receiving means and the manual switches to second receiving means; second receiving means for decoding signals supplied from the signal transmission means, and controlling the first switching means.
