Abstract
The utility model relates to a control circuit, particularly relates to and provides the control circuit capable of realizing zero power consumption for a pulse valve in the standby state. The control circuit comprises resistances R1 and R2, optocouplers D1 and D2, and a singlechip N3, wherein the two optocouplers D1 and D2 are respectively connected with the singlechip N3 through the resistances R1 and R2; the two optocouplers D1 and D2 are connected with the pulse valve through diodes D1 and D2; the two diodes are connected with the pulse valve in opposite positive and negative poles; and one end feet of the optocouplers D1 and D2 are connected with the ground. The control circuit capable of realizing zero power consumption for the pulse valve in standby state not only can realize zero power consumption for the pulse valve in standby state, but also has very high anti-interference effect on abnormal disturbance of power grid. The circuit greatly reduces the standby power of a whole set of household electrical appliances, thereby meeting the requirement of energy star of European Union.
Description
Technical field
The utility model relates to a kind of control circuit, specifically, relates to a kind of pulse valve standby zero-power control circuit.
Background technology
In the prior art, the defective that has electrical network zero cross detection circuit consumed power is, pulse valve is a consumed power always, has caused the waste of the energy, particularly in field of household appliances, and the market competitiveness of the household electrical appliances that the power consumption during standby can reduce greatly.
Summary of the invention
The purpose of this utility model is to overcome above defective, and a kind of pulse valve standby zero-power control circuit is provided.
The technical scheme of pulse valve standby zero-power control circuit of the present utility model is such: it comprises resistance R 1, R2, optocoupler D1, D2, single-chip microcomputer N3, wherein, two optocoupler D1, D2 link to each other with single-chip microcomputer N3 by resistance R 1, R2 respectively, two optocoupler D1, D2 are connected with pulse valve by diode D1, D2, and the both positive and negative polarity that two diodes are connected with pulse valve is opposite, holds pin ground connection for one of optocoupler D1, D2.
Optocoupler D1, D2 can be set to relay.
Pulse valve standby zero-power control circuit of the present utility model, zero-power in the time of not only can making the pulse valve standby, the unusual harassing and wrecking to electrical network simultaneously have very high anti-interference effect.This circuit has reduced the standby power of household appliances complete machines greatly, thereby satisfies the requirement of European Union's " Energy Star ".
Description of drawings
Fig. 1 is the circuit diagram of pulse valve standby zero-power control circuit of the present utility model.
Embodiment
Embodiment 1
It comprises resistance R 1, R2 pulse valve standby zero-power control circuit of the present utility model, optocoupler D1, D2, single-chip microcomputer N3, wherein, two optocoupler D1, D2 link to each other with single-chip microcomputer N3 by resistance R 1, R2 respectively, two optocoupler D1, D2 are connected with pulse valve by diode D1, D2, and the both positive and negative polarity that two diodes are connected with pulse valve is opposite, holds pin ground connection for one of optocoupler D1, D2.
When needs when pulse valve sends direct impulse, only need single-chip microcomputer RA0 pin output low level, RA1 pin output high level are got final product; In like manner, when needs when pulse valve sends negative-going pulse, only need single-chip microcomputer RA0 pin output high level, RA1 pin output low level are got final product; If pulse valve is not when needing to keep pulse, the level that RA0 pin and RA1 pin are exported simultaneously gets final product.Simultaneously, this circuit can be controlled the number that the single pulse valve sends pulse very easily.Thereby guarantee that pulse valve is a zero-power under holding state.
Because pulse valve link circuit is pure hardware mode gating pulse valve conducting polarity, therefore, the unusual harassing and wrecking of electrical network are had very high anti-interference, do not exist because the false triggering phenomenon generation that the unusual harassing and wrecking of electrical network cause.
Embodiment 2
The difference of present embodiment and embodiment 1 is that optocoupler D1, the D2 of present embodiment can be set to relay, but the power consumption that relay when work needs will be much larger than optocoupler, and simultaneously, the action frequency life-span of relay will be well below optocoupler.
Claims (2)
