Original composition of a remote controller is adopted, a power switch can be directly controlled by the original remote controller, and the utility model has the advantages of easy use, power consumption saving, small size, convenient installation, stable performance, etc. The insufficiency of a touching switch can be avoided by adopting a silicon controlled rectifier acting as a switch, a zero trigger circuit can also be added, the shock to electric appliances by surge current can be avoided, and the utility model can be widely used in remote controlling electric appliances.

Description

Compatible type silicon controlled remote control switch

The utility model relates to a kind of thyristor supply switch, and the particularly a kind of compatible type silicon controlled remote control switch that can control with the former remote controller in the remote control electrical appliance belongs to the electronic switch field.

The remote controller that existing household electrical appliance are equipped with all can not remote-controlled start-up, need just can carry out remote control after the manual start, use inconvenient, in order to address this problem, can between household electrical appliance and power supply, install a kind of remote control socket additional, but must increase by one with the opening or closing of the supporting special remote circuit of remote controller of remote control socket, like this, just make every electrical equipment need 2 remote controllers, increased new trouble, simultaneously, what this remote controller used is relay contact formula switch, is easy to generate spark and causes faults such as contact sintering or loose contact.

The purpose of this utility model is in order to overcome above-mentioned weak point of the prior art, and it is reliable to design a kind of working stability, easy to use, the compatible type silicon controlled remote control switch that can directly utilize the remote controller of original electrical equipment to carry out the power supply remote control.

Technical measures of the present utility model are the mains switches that replace controlled electric appliance with bidirectional triode thyristor, the circuits for triggering control that the trigger voltage of the bidirectional triode thyristor control utmost point is made up of an one-way SCR that turn-offs only, the off signal that the control utmost point of this one-way SCR is subjected to export in remote signal and the electrical equipment is simultaneously controlled.Its structure is by decompression rectification power, remote control signal receiver, bidirectional triode thyristor B1 and circuits for triggering, it is characterized in that circuits for triggering are by the one-way SCR B2 that can turn-off, photoelectrical coupler BC1, triode B3, diode D1, D2, electrochemical capacitor C1, C2 and resistance R 2-R5 form, its annexation is: the termination power positive pole of the anode of B2 and the collector electrode of B3 and R5, power cathode ground connection, the Vcc end of another termination remote control signal receiver of R5, the Vdd end ground connection of receiving system, the signal output part of receiving system connects the C1 positive pole, the C1 negative pole connects the anodal and D2 negative pole of D1, the D1 negative pole connects the anodal and B3 base stage of C2, anodal and the C2 minus earth of D2, the B3 emitter meets R3, the 5th pin of another termination of R3 B2 control utmost point and BC1, the 4th pin ground connection of BC1, BC1 the 1st pin and the 2nd pin after resistance R 4 series connection respectively with remote control electrical appliance in off signal output X3 be connected with X4, the B2 negative electrode meets R2, the control utmost point of another termination bidirectional triode thyristor of R2 B1, one end XP2 of the electrode T1 ground connection of B1 and input power supply, another electrode T2 of B1 meets an end X2 of out-put supply, and the other end X1 of out-put supply is connected with the other end XP1 of input power supply.This remote control switch can replace former mains switch and directly be contained on the position of former mains switch.During start, by the arbitrary signal key on the former electric appliance remote controller once and send remote signal, this signal is received by the receiving system of this switch, the signal of output through D1 and D2 voltage multiplying rectifier after B3 amplify, make the B2 conducting and keep conducting, B2 provides trigger current to B1, makes the B1 conducting and starts shooting.During shutdown, press the closing key on the remote controller, the computer processor in the controlled electric appliance sends off signal, through photoelectrical coupler BC1 coupling, makes the B2 grounded-grid and ends, and then make B1 lose trigger current and end, and cuts off the electricity supply and is equivalent to shutdown.

Accompanying drawing 1 is an embodiment of the present utility model;

Accompanying drawing 2 is another embodiment of the present utility model.

Referring to accompanying drawing, wherein all the measure part with above-mentioned is identical for the circuit of Fig. 1 and annexation thereof etc., Fig. 2 only increases the optical coupling reverse-blocking tetrode thyristor driver BC2 of a band zero cross fired than Fig. 1, make it increase the zero cross fired performance, avoid the impact of surge current to electrical equipment, its annexation is: the R2 of circuits for triggering output is disconnected 1st pin of back reconfiguration at BC2 from the control utmost point of B1, and the 4th pin of BC2 connects the control utmost point of B1, the 2nd pin ground connection of BC2, the 6th pin of BC2 is through resistance R 6 ground connection.B1 in the accompanying drawing selects the bidirectional triode thyristor of models such as BTA06 for use, B2 selects the one-way SCR of models such as BT1690 for use, B3 selects negative-positive-negative transistor for use, BC1 selects the photoelectrical coupler of models such as 4N33 for use, BC2 selects the optical coupling reverse-blocking tetrode thyristor driver of models such as MOC3041 for use, and the receiving system of remote signal is selected for use and the corresponding infrared receiving device of the remote-controlled launcher of controlled electric appliance or ultrasonic probe, ultrasonic receiver or radio receiver.Be used to change when having electrical equipment now, the position of former mains switch just in time can be installed, and only the output of the off signal in the remote control electrical appliance need be connected with X4 with X3 respectively to get final product.

The utlity model has the characteristics with former remote controller compatibility, can directly control with former remote controller Power switch, easy to use, power consumptive province, volume be little, be convenient to install and stable and reliable for performance etc. Advantage again because selecting silicon controlled as switch, has been avoided the deficiency of contact switch, also can increase Zero-cross triggering circuit avoids surge current to the impact of electrical equipment, is adapted in the remote control electrical appliance extensive Use.
