The power consumption electric current of the reception amplifier in the existing remote control switch is all bigger, the essential running current (about about 2MA) that guarantees it, otherwise can't normally receive amplification work.A kind of multi-channel remote control switch of incandescent lamp as shown in Figure 1, it is made up of reception amplifier, decode controller and reverse-blocking tetrode thyristor.About the about 2MA of its reception amplifier operating current, if change the bulb among Fig. 1 (incandescent lamp) into electricity-saving lamp or fluorescent lamp, circuit shown in Figure 1 just can't have been worked under the light fixture off state.Its analysis of causes is as follows:
Because electricity-saving lamp, fluorescent lamp its leakage current under off state just become unique source of reception amplifier operating current in the accompanying drawing 1.And about the about 0.1MA of its leakage current, can not satisfy the needs of keeping reception amplifier operate as normal 2MA electric current far away.Obviously this circuit can only be controlled the electrical equipment that turn-offs impedance lower (50K ohm following as incandescent lamp bulb etc.).And to controlling just powerless as the electrical equipment of shutoff impedances such as electricity-saving lamp higher (about about 1000K ohm).
Along with the raising of standard of living and the needs of saves energy, the ratios in light fixture electrical equipment such as fluorescent lamp, electricity-saving lamp are increasing, and existing remote control switch can not be used for the control of this electric appliances.Like this, the popularity rate of remote controller is just very low, has greatly hindered the development of remote control switch industry simultaneously again.
For this reason, remote control switch manufacturer can only adopt now some such as: increasing by a wire becomes and increases storage battery in three-wire system or the machine or shunt capacitance etc. (general name increase income method) increases the power supply supply on electrical appliance way, to satisfy the requirement of reception amplifier to power supply.To scheme to improve remote control switch popularity rate, expansion market.But the product that adopts these technical measures is the cost height often, and difficulty is installed, and causes operating expenses to increase.
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, and a kind of intelligent energy-saving wireless multi-path remote control switch that can be used for fluorescent lamp, the contour shutoff impedance load of electricity-saving lamp is provided.
The key of technology of the present utility model is an atomic weak leakage current when how to effectively utilize the controlled electric appliance shutoff, and the reception amplifier in the remote control switch can normally during controlled electrical appliance is in off state effectively be worked.
Intelligent energy-saving wireless multi-path remote control switch of the present utility model comprises: reception amplifier, decode controller and the reverse-blocking tetrode thyristor circuit of being controlled by decode controller is characterized in that:
Described decode controller adopts single-chip microcomputer, and the power end of described reception amplifier is connected in an output of single-chip microcomputer, is using electric loading blocking interval single-chip microcomputer to the reception amplifier intermittent power supply;
Described reverse-blocking tetrode thyristor circuit is by the bidirectional triode thyristor Q1 of two series connection, Q2, resistance R, diode D2, D3, D5, voltage stabilizing didoe D1, D4, and capacitor C is formed, the resistance R series connection voltage stabilizing didoe D4 ground connection of one termination bidirectional triode thyristor Q1, the positive pole of diode D3 connects the common port of resistance R and voltage stabilizing didoe D4, the positive pole of diode D5 connects bidirectional triode thyristor Q2 one end, diode D3, D5 negative pole (Vdd) is by filter capacitor C ground connection, the reference voltage branch road of being made up of diode D2 and voltage stabilizing didoe D1 is connected between another output of single-chip microcomputer and the ground, bidirectional triode thyristor Q2 triggers the negative pole of termination voltage stabilizing didoe D1, and bidirectional triode thyristor Q1 trigger end connects the 3rd output of single-chip microcomputer.
Below in conjunction with the embodiment accompanying drawing the utility model is further specified.
Fig. 1 is the circuit theory diagrams of existing wireless multi-path remote control switch;
Fig. 2 is this intelligent energy-saving wireless multi-path remote control switching circuit schematic diagram;
The power supply timing figure that Fig. 3 provides for intermittent power supply software.
Multi-channel remote control switch is applicable to the control of electrical appliances such as incandescent lamp as shown in Figure 1, and it is made up of reception amplifier, decode controller and reverse-blocking tetrode thyristor circuit.Reception amplifier receives the control signal that radiating circuit sends, and is amplified into the decode controller decoding, and decode controller produces start pulse signal, makes the reverse-blocking tetrode thyristor action, realizes the opened/closed of electrical appliance.
The right is the reverse-blocking tetrode thyristor circuit among Fig. 2, and it is by bidirectional triode thyristor Q1, Q2, resistance R, and diode D2, D3, D5, voltage stabilizing didoe D1, D4, and capacitor C forms, circuit can provide the full-wave rectifier power supply Vdd by the power supply of electrical appliance leakage current.Wherein Q2 capacitor C when the Q1 conducting is charged to conducting behind the voltage that voltage stabilizing didoe D1 limits, power loss when being used for reducing the remote control switch conducting.Resistance R is the electric current that is used for limiting when turn-offing, and C is the energy storage filter.
This circuit can be obtained the electric current that doubles half-wave rectifying circuit at the load blocking interval, has utilized leakage current fully, improves power supplying efficiency.After bidirectional triode thyristor Q1 conducting, because the conducting of Q2 makes whole remote control switch power loss extremely low.Q2 is composed in series similar diode circuit of voltage regulation replacement by voltage stabilizing didoe or by a plurality of diode forward in traditional product, and its power loss is than more than the big 5-10 of this circuit times.Conducting has reached purpose of energy saving to above-mentioned thyristor Q2 in the later stage.The bidirectional triode thyristor Q2 of described reverse-blocking tetrode thyristor circuit can use triode or fet or IGBT electronic power switch to replace.
Shown decode controller adopts single-chip microcomputer, and the power end of reception amplifier is connected in an output of single-chip microcomputer, is using electric loading blocking interval single-chip microcomputer to the reception amplifier intermittent power supply.Single-chip microcomputer is finished the intermittent power supply of signal decoding, receiver and the control of reverse-blocking tetrode thyristor circuit triggers etc.Present widely used decoder (as 2272 etc.) also is a single-chip microcomputer in fact.The utility model has increased an intermittent power supply management software (owing to not increasing new hardware, so cost is constant) on original decoding, controlling and driving function basis, realized the desired intermittent power supply function of the utility model.
Using the electric loading blocking interval, by single-chip microcomputer to the reception amplifier intermittent power supply.The power supply timing figure that the intermittent power supply management software provides as shown in Figure 3.After the start, single-chip microcomputer checks whether P6.1, P6.0 equal " 1 ", if P6.0 is not equal to " 1 ", and intermittently power supply of level forward; If P6.0 equals " 1 ", carry out signal and receive, handle, trigger the ghyristor circuit action.From Fig. 3, can clearly be seen that: using the electric loading blocking interval, by single-chip microcomputer to the duty ratio of reception amplifier power supply=10MS:(10MS+990MS)=10MS:1000MS=0.01=1%
So, using the electric loading blocking interval, the average operating current I=of remote control switch complete machine (the average operating current of reception amplifier)+(single-chip microcomputer electric current on duty)=(2MA* duty ratio)+0.015MA=2MA*1%+0.015MA=0.035MA.
