On the basis of the power distribution combination switch of a common domestic appliance, the utility model is added with a multi-channel remote control function, etc. The utility model can solve the technical problem of remotely controlling and directly controlling all the domestic appliances, an operational amplifier is adopted to form an active band-pass filter, so the utility model can select frequency of remote control command signals with different frequencies. The utility model is a power distribution device for domestic appliances provided with one to four paths which are all allocated with binding posts and sockets, and an infrared remote controller can remotely control and directly control the switching-on, switching-off, voltage regulating, light regulating and speed regulating in ten meters.
Description
The utility model relates to basic electronic circuit and power distribution two technical fields.
The common unit switch and the single channel remote control switch that supply the household electrical appliance distribution to use have appearred now on the market.The former is made up of switch and socket, can only directly control the open and close of household electrical appliance, and does not have a distant control function, and it is convenient inadequately to use.Though the latter is remote-controlled, just single channel can only be controlled single electrical appliance, and has and must with the directly actuated shortcoming of hand, not have pressure regulation, light modulation, speed-regulating function again with remote controller.
The utility model is at the deficiency of above-mentioned two kinds of panel switches and propose, both advantages together with it, on the basis of common unit switch, set up the multi-channel remote function, make all household electrical appliance can realize remote control and directly control, and can have functions such as pressure regulation, light modulation, speed governing as required.Thereby make the utility model can replace existing various home-use panel switches, become desirable family's modernization apparatus.
For simplicity, below " infra-red remote control is directly controlled the multi-functional unit switch of multichannel " abbreviated as " unit switch ".
The utility model is made up of remote controller (infrared ray instruction reflector) and unit switch (including electronics receiving lines and power distribution circuit) two large divisions.
Fig. 1 is a theory diagram.In remote controller, utilize the pulse of different frequency that the infraluminescence pipe is modulated, make its Infrared that penetrates different frequency instruct control switchgroup.Deliver to the active band-pass filter II of forming by operational amplifier after reception amplifying circuit I in the unit switch is amplified the command signal reception and carry out frequency-selecting, after amplifying, frequency-selecting command signal is demodulated to DC level by carrier wave demodulation circuit III, drive corresponding executive circuit IV (or V) work, reach the purpose of control switch keying and pressure regulation, light modulation, speed governing.
The embodiment line map is seen Fig. 2 and Fig. 3.Fig. 2 is the line map of remote controller, and Fig. 3 is the line map of four-way unit switch.
In the remote controller shown in Figure 2, adopt time-base circuit 555 elements such as grade to form multivibrator, its frequency of oscillation f=1.44/(W+2R) C.When R and C get definite value, change W, just can change its frequency of oscillation.Principle is provided with adjustable resistance W in view of the above
