Background technology
The product stand-by power consumption is meant that product is connected on the power supply and is in wait state, the power consumption during its major function of off-duty.It is a kind of energy waste basically; The social investigation in Oxford University shows; Family's standby energy consumption level on average takies 8% of power consumption total amount, and the energy that various countries consume because of standby accounts for 3%～13% of energy consumption sum, and the standby energy consumption of China is higher than average level.
The standby energy consumption power of household electrical appliances commonly used is respectively: 3.47 watts in air-conditioning, 2.46 watts of washing machines, 4.09 watts in refrigerator, 2.78 watts of microwave ovens; 6.06 watts of smoke exhaust ventilators, 19.82 watts of electric cookers, 8.07 watts of colour TVs, 28 watts of video tape recorders; 13.37 watts of DVD players, 10.97 watts in VCD machine, 12.35 watts of sound equipment power amplifiers, 1.34 watts of charger for mobile phone; 7.69 watts of displays, 35.07 watts in PC main frame, 5.71 watts of facsimile machines, 9.08 watts of printers.Add up these, be equivalent to idle the time, these household electrical appliances will be spent in one day in power consumption 4.These annual total standby power consumption amounts are equivalent to the energy output in 4 years in Daya Gulf power station up to 35,400,000,000 degree.The scholarly forecast analysis is pointed out, increases computist's electric weight according to the household electrical appliances production and consumption, and supposes standby every day 2 hours; Save electric energy to accumulative total in 2012 and just can reach 1,161 hundred million degree; Consumer's cost saving reaches 66,100,000,000 RMB, and 3,940 ten thousand tons of the dischargings of minimizing carbon reduce 47.3 ten thousand tons of discharged nitrous oxides; Reduce 616.6 hundred million tons of SO2 emissions, reduce solid particulate matter and discharge 2,880,000 tons.
Therefore wiring board in the market can't be discerned the holding state of electric equipment, when electrical appliance is in holding state, just causes energy waste, reduces standby energy consumption to alleviating ambient pressure, energy-conservation and reduce household consumption etc. and all have positive meaning.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of the utility model is to provide a kind of energy-conservation wiring board, monitors its power consumption; And power P=IV, voltage is fixed as civil power 220V, and electric current changes with the electrical appliance state variation; Therefore can be with current monitoring as the foundation whether loaded work piece is arranged, microprocessor is judged through acquired signal and the operating state of electrical equipment is in holding state as if household electrical appliance; Then cut off the wiring board power supply, have characteristics simple in structure, easy to use.
To achieve these goals, the technical scheme of the utility model employing is:
A kind of energy-conservation wiring board; Comprise mains switch; A plurality of supply terminalss and housing, the output of mains switch is connected with the input of AC/DC conversion module, and the output of AC/DC conversion module is connected with the power end of microprocessor; The output of latching relay is connected with the input of energy consumption monitoring circuit; The output of energy consumption monitoring circuit is connected with the input of A/D modular converter, and the output of A/D modular converter is connected with the input of microprocessor, and the output of microprocessor is connected with latching relay.
Described energy consumption monitoring circuit comprises the instrument transformer T that is connected in the live wire, and the end of instrument transformer T is provided with rectifier D, and the end of rectifier D connects the positive pole of polar capacitor C.
Because the utility model is core with the microprocessor, judges the electrical work state through the variation of monitoring current signal, judges whether wiring board works in holding state, thereby cut off the electricity supply to have characteristics simple in structure, easy to use.

Fig. 2 is the utility model energy consumption monitoring circuit theory diagrams.
Embodiment
Be further described below in conjunction with the structural principle and the operation principle of accompanying drawing the utility model.
With reference to Fig. 1; A kind of energy-conservation wiring board comprises mains switch, a plurality of supply terminalss and housing; The output of mains switch is connected with the input of AC/DC conversion module; The output of AC/DC conversion module is connected with the power end of microprocessor, and the output of latching relay is connected with the input of energy consumption monitoring circuit, and the output of energy consumption monitoring circuit is connected with the input of A/D modular converter; The output of A/D modular converter is connected with the input of microprocessor, and the output of microprocessor is connected with latching relay.
With reference to Fig. 2, described energy consumption monitoring circuit comprises the instrument transformer T that is connected in the live wire, and the end of instrument transformer T is provided with rectifier D, and the end of rectifier D connects the positive pole of polar capacitor C.
In the time of work, the mains switch of closed wiring board, the work of AC/DC conversion module; Give microprocessor power supply,, therefore need convert current signal to voltage signal to handle because microprocessor can only the processes voltage signal and can not directly handle current signal; Instrument transformer that number of secondary turns is very little of series connection is accomplished the I/V translation function on the live wire, can know according to power P=IV; Voltage signal V after the conversion and electrical appliance power consumption P are directly proportional, but voltage signal V is an AC signal, can not be directly by microprocessor processes; Therefore need come voltage signal V is carried out rectification with rectifier; Become direct voltage, with polar capacitor it is carried out filtering simultaneously, then the A/D converter of input microprocessor.Whether microprocessor comes specified data in the standby data field according to the A/D transformation result; Thereby confirm the operating state of electrical equipment, when having confirmed electrical work at holding state, microprocessor is given signal of latching relay; Latching relay breaks off, and whole circuit is in off-state.
