Description
Technical field
The utility model relates to a kind of radio remote control switch circuit of using in the household electricity field.
Background technology
In daily life, the switch of illuminating lamp is often to use, but existing lighting switch mostly is installed in the position on doorway, need stand up during switch to find switch to operate; Make troubles for old man, children or handicapped people, be disinclined to leave the bed and turn off the light, just cause energy waste.
Summary of the invention
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of radio remote control switch circuit that can remote control switch is provided.
Its technical scheme is: power-supplying circuit, voltage stabilizing circuit and remote-control receiving circuit when comprising power-supplying circuit when closing, unlatching, power-supplying circuit is connected to power supply by the input of rectifying block DZ1 through capacitor C 3 when closing, and capacitor C 3 is parallel with resistance R 3 and forms; Power-supplying circuit is by the input of B level connection of current transformer rectifying block DZ2 during unlatching, and the current transformer B just utmost point passes a power line composition; Shunt capacitance C2 and voltage stabilizing didoe DW form voltage stabilizing circuit again after by the series connection of the output of rectifying block DZ1, DZ2; Behind the signal output part and power circuit negative pole parallel resistance R1 and capacitor C 1 of remote-control receiving circuit by wireless receiving module IC1, the signal output part of IC1 is the base stage of series resistance R2, light-emitting diode D and triode Q successively again, and the collector electrode series relay J of triode Q connects that power circuit is anodal to be formed; The contact J-1 of relay J is connected between the electric power loop.
The utility model is fit to all kinds of crowds to be used, and easy for installation, and cost of manufacture is low, is particluarly suitable for that patient uses under no entourage's situation in the hospital, has avoided energy waste.
Description of drawings
Accompanying drawing is the circuit theory diagrams of a kind of embodiment.
Embodiment
Be further described with regard to its operation principle below in conjunction with accompanying drawing: mainly when closing power-supplying circuit, power-supplying circuit, voltage stabilizing circuit and remote-control receiving circuit are formed when opening, power-supplying circuit is connected to power supply by the input of rectifying block DZ1 through capacitor C 3 when closing, and capacitor C 3 is parallel with resistance R 3 and forms; Power-supplying circuit is by the input of B level connection of current transformer rectifying block DZ2 during unlatching, and the current transformer B just utmost point passes a power line composition; Shunt capacitance C2 and voltage stabilizing didoe DW form voltage stabilizing circuit again after by the series connection of the output of rectifying block DZ1, DZ2; Behind the signal output part and power circuit negative pole parallel resistance R1 and capacitor C 1 of remote-control receiving circuit by wireless receiving module IC1, the signal output part of IC1 is the base stage of series resistance R2, light-emitting diode D and triode Q successively again, and the collector electrode series relay J of triode Q connects that power circuit is anodal to be formed; The contact J-1 of relay J is connected between the electric power loop.
Operation principle:
At ordinary times, wireless receiving module IC1 does not accept wireless signal, light-emitting diode D and triode Q not conducting entirely, the static original state of keeping of relay J.
As remote control open signal the time, wireless receiving module IC1 accepts wireless signal, light-emitting diode D and triode Q conducting, the Be Controlled circuit is connected in the relay J adhesive.
When the signal of the pass of remote control, wireless receiving module IC1 accepts wireless signal, and light-emitting diode D and triode Q are become by conducting and end, and relay J discharges, and disconnects the Be Controlled circuit.
