The invention can provide control conditions for using an electrical appliance in an efficient, energy-saving and safe way. Meanwhile, the device has simple structure and low cost.
Description
Technical field
The present invention relates to induction installation, relate in particular to the device that control is responded in the variation that utilizes the microwaves that the on off state instantaneous variation causes.
Background technology
Its energy operate as normal when a lot of consumers all need standby power supply to have a power failure with assurance, the control mode that adopts is the automatic standby power supply that starts under power-off condition usually, such as: emergency light.If wish energy-conservation more need to increase more control device such as acoustic control, light-operated switch etc., increased its cost widely.And more consumer, but be to need electricity consumption in use, (as some quantity-produced chemical plants) can not cut off the power supply in the use, for this class consumer, if adopt as emergency light do not have the i.e. mode of startup standby power supply automatically of electricity, automatic power causes damage to consumer thereby will cause itself need not electricity consumption the time but; And for example illumination all is by mains-supplied usually now, and is very dark when having a power failure suddenly, and walking is easy to come to harm because of tripping or colliding with; If be equipped with a small-sized reserve battery to lamp, can take neither that too many spacial influence is attractive in appearance just to solve the inconvenience that unexpected power failure is caused again, but reserve battery finite capacity, also to take into account energy-conservation, this just needs to judge to be to have a power failure or close with decision whether should start standby power supply naturally, start simultaneously how could realize behind the standby power supply energy-conservation.Yet there are no relevant report.
Summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming and provide a kind ofly provide controlled condition efficient, energy-conservation and safe handling, and switch status induction system simple in structure, with low cost for the electricity consumption device.
Switch status induction system of the present invention comprises sensor measuring unit, micro-control unit and output unit, and wherein: sensor measuring unit output terminal is connected with the micro-control unit input end, and the micro-control unit output terminal is connected with output unit.
Above-mentioned switch status induction system, wherein: the sensor measuring unit is made of L wiretap signal acquisition circuit and N wiretap signal acquisition circuit, micro-control unit is signal Processing and control circuit, output unit is the steering order output circuit, L wiretap signal acquisition circuit output, N wiretap signal acquisition circuit output are connected with the control circuit input end with signal Processing respectively, and signal Processing is connected with steering order output circuit input end with the control circuit output terminal.
Above-mentioned switch status induction system, wherein: also comprise the telecommunications wave transmitting circuit.
The present invention compared with prior art, as can be known from the above technical solutions, the switch of control electricity consumption device, power lead is connected with sensor measuring unit input end near it, the sensor measuring unit is connected with physical signallings such as the power lead differential frequency electromagnetic wave of switch or sound to this and gathers, and the physical signalling that collects changed, be converted to the electric signal that micro-control unit can be discerned and handle; Micro-control unit is realized collecting the functions such as analysis, processing and storage of differential frequency electromagnetic wave amplitude (differential frequency amplitude) or voice signal variance data; Thereby judge switch is to open or closure state, switch opens represents that the electricity consumption device is in the nature off-position and need not work, switch closure is represented the outage suddenly at work of electricity consumption device, require to handle in conjunction with judged result according to the control that sets in advance, output unit exports the micro-control unit result with control electricity consumption device.As be used for throwing light on, stopping civil power and judging switch is closure state, if the control that is provided with is to start standby power supply to continue power supply, at this moment can turn bulb power down or not prolong the power-on time of standby power supply to reach purpose of energy saving to the part bulb powered by control.The present invention is simple in structure, with low cost, can provide controlled condition efficient, energy-conservation and safe handling for the electricity consumption device.
Below further specify beneficial effect of the present invention by embodiment.
Description of drawings
Fig. 1 is circuit theory diagrams of the present invention;
The schematic block circuit diagram of Fig. 2 embodiment 1;
Fig. 3 is the schematic block circuit diagram of embodiment 2.
Embodiment
Embodiment 1:
Referring to Fig. 1-2, switch status induction system, the sensor measuring unit is made of L wiretap signal acquisition circuit and N wiretap signal acquisition circuit, micro-control unit is signal Processing and control circuit, output unit is the steering order output circuit, L wiretap signal acquisition circuit output, N wiretap signal acquisition circuit output are connected with the control circuit input end with signal Processing respectively, and signal Processing is connected with steering order output circuit input end with the control circuit output terminal.
Its principle of work is as follows:
L wiretap signal acquisition circuit input end is connected with the power lead L that is connected with switch, N wiretap signal acquisition circuit input end is connected with power lead N.The system power supply line is the same with regard to image antenna, can when outage, receive the 50Hz-70Hz electromagnetic wave signal of free-running frequency in the environment, if the length of two wires is more or less the same, differential frequency electromagnetic wave amplitude (differential frequencyamplitude) difference that it receives also be more or less the same (under the closed condition of switch), but if conductor length differs greatly (under the disconnection situation of switch), the differential frequency electromagnetic wave amplitude that two wires receive is just variant.Whether the identical disconnection of judging switch is with closed so just can to judge the signal that L wiretap signal acquisition circuit and N wiretap signal acquisition circuit (with the induction of two receiver modules because switching device can be received either party of two fire/telegram in reply road) receive by signal Processing and control circuit, thereby realizes the control to the electricity consumption device.If switch closure illustrates that it is outage, thereby starts the standby power supply power supply or reduce electricity consumption device power simultaneously, to reach energy-conservation, efficient or safe effect; Switch disconnects explanation electricity consumption device itself does not just need work, with regard to not needing it is controlled yet.
Embodiment 2:
Referring to Fig. 1,3, switch status induction system, the sensor measuring unit is made of L wiretap signal acquisition circuit and N wiretap signal acquisition circuit, micro-control unit is signal Processing and control circuit, output unit is steering order output circuit and telecommunications wave transmitting circuit, L wiretap signal acquisition circuit output, N wiretap signal acquisition circuit output are connected with the control circuit input end with signal Processing respectively, and signal Processing is connected with steering order output circuit input end with the control circuit output terminal.
Its principle of work is as follows:
The telecommunications wave transmitting circuit is connected with the power lead that is connected with switch, replaces the electromagnetic wave signal that exists in the environment to power lead emission electric signal, and all the other principle of work are with embodiment 1.
