Fig. 2 is the remote-control receiving circuit structural representation of the utility model one embodiment;
Fig. 3 is the anti-interference remote control low power consumption standby socket physical circuit figure of the utility model one embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
See Fig. 1, the utility model provides a kind of anti-interference remote control low power consumption standby socket, this socket 100 comprises housing and is located at the insertion hole groups 10 on described housing and is loaded on the anti-interference remote control micro-power consumption standby control circuit 20 in described housing, and described anti-interference remote control micro-power consumption standby control circuit 20 comprises remote-control receiving circuit 21, current sampling circuit 22, signal amplification circuit 23, delay circuit 24, executive circuit 25 and the power circuit 26 for above-mentioned each circuit supply.Remote-control receiving circuit 21 of the present utility model is preferably infrared remote control reception circuit, and it has infrared remote control receiver part.
Preferably, at least two current-limiting resistances are provided with between described remote-control receiving circuit 21 and signal amplification circuit 23.Composition graphs 2, described remote-control receiving circuit 21 has and detects electronic circuit 211 and triggers circuit 212, described detection electronic circuit 211 for detecting in the scheduled time whether receive at least twice remote signal, if then transfer to triggers circuit 212 to process.Triggers circuit 212 sends control signal after described detection electronic circuit 211 receives at least twice remote signal in the given time, works with control signal amplifying circuit 23 and delay circuit 24.If detect electronic circuit 211 in the given time the remote signal being less than twice to be detected, then shake control receiving circuit 21 can not control signal amplifying circuit 23 and delay circuit 24 work, whereby, the disturbing pulse that socket 100 only receives an infrared signal or disturbed by circuit, spatial electromagnetic interference, infrared light etc., can not be influenced, thus shield the impact of most interference signal, significantly reduce the probability of misoperation.
Embodiment shown in composition graphs 3 again, in this embodiment, described signal amplification circuit 23 and delay circuit 24 are integrated on same chip, the remote control device of remote-control receiving circuit 21 is infrared receiving terminal HWT, it was (such as 1 ~ 2 second scheduled time, can set according to demand) in receive after twice infrared remote-controlled signal, send control signal electric current, signal code is through current-limiting resistance R10, R9 is connected to signal and amplifies and delay circuit input IN, after this signal amplifies and delay circuit work, its output OUT exports the time delay high level of tens of seconds, this high level is through current-limiting resistance R5 driving transistors Q1 conducting, relay J adhesive, the socket of socket and electric main are connected, powering to the electrical appliance inserted thereon makes this electrical appliance enter holding state.
In this latency period, the remote controller that user manipulates this electrical appliance can control it and enter operating state.Now the operating current of electrical appliance makes the current transformer worn thereon export an induced voltage, this voltage is added in transistor Q2 base stage after rectifying and wave-filtering, make Q2 conducting, low level is added in signal amplification hold with delay circuit input DELIY, make its output OUT maintain high level output always, relay J is in attracting state all the time, thus socket makes this electrical appliance electrically connect with city until user turns off this electrical appliance with remote controller always.
Be more preferably, after user turns off electrical appliance, signal amplifies makes the socket of this socket maintain power-up state a period of time with the delay circuit in delay circuit, and at this moment, if user sends remote control command, this electrical appliance can enter operating state again.
Further, the time that electrical appliance on socket 100 is in holding state has exceeded predetermined delay time and has not received and manipulated instruction accordingly, then signal amplification will revert to low level with delay circuit output OUT, transistor Q1 ends, relay J discharges, the socket of socket 100 and electric main disconnect, make to insert electrical appliance thereon and civil power thoroughly disconnects, the remote-control receiving circuit 21 in this socket 100 is only had to have weak current to flow through, thus eliminate the stand-by power consumption of electrical appliance, it also avoid electrical appliance simultaneously and access civil power for a long time and incident on fire, the risk of burning.
In sum, the utility model arranges anti-interference remote control micro-power consumption standby control circuit in socket, this circuit comprises remote-control receiving circuit, current sampling circuit, signal amplification circuit, delay circuit, executive circuit, and be the power circuit of above-mentioned each circuit supply, at least two current-limiting resistances are provided with between described remote-control receiving circuit and signal amplification circuit, described remote-control receiving circuit has for detecting the detection electronic circuit whether receiving at least twice remote signal in the scheduled time, and after receiving at least twice remote signal in the given time for described detection electronic circuit, send the triggers circuit of control signal, whereby, the utility model makes the probability of socket misoperation by external interference signals decline to a great extent, improve the reliability of use.
Certainly; the utility model also can have other various embodiments; when not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the utility model, but these change accordingly and are out of shape the protection range that all should belong to the claim appended by the utility model.
