With reference now to accompanying drawing, describe embodiment of the present utility model, the similar elements label is represented similar elements in the accompanying drawing.As mentioned above, the utility model provides a kind of measurement display device that is used for electric appliance energy-saving, this device can show energy-conservation indexs such as the power consumption situation of electrical equipment and carbon emission amount in real time, the consumer can be under the situation that guarantees comfort level, judge the more power saving of which kind of mode of operation intuitively, more save, thereby help the consumer to realize the life pattern of environmental protection, energy-saving and emission-reduction.
Elaborate the technical scheme of the utility model embodiment below in conjunction with accompanying drawing.As shown in Figure 1, the measurement display device that is used for electric appliance energy-saving of present embodiment comprises current-voltage sampling circuit 101, the signal processing circuit 102 that is electrically connected with described current-voltage sampling circuit 101 and the display circuit 103 and the parameter setting circuit 104 that are electrically connected with described signal processing circuit 102.Described signal processing circuit 102 comprises analog to digital conversion circuit 1021, central processing unit circuit 1023, real time clock circuit 1022, data storage circuitry 1025 and peripheral interface circuit 1024.Analog-digital conversion circuit as described 1021 is electrically connected with described current-voltage sampling circuit 101 and described central processing unit circuit 1023, described central processing unit circuit 1023 is electrically connected with described display circuit 103, described real time clock circuit 1022, peripheral interface circuit 1024 and data storage circuitry 1025 respectively, and described peripheral interface circuit 1024 is electrically connected with described parameter setting circuit 104.
As preferred embodiment of the present utility model, as shown in the figure, present embodiment also comprises warning circuit 106, control circuit 105 and the communication interface circuit 107 that is electrically connected with described peripheral interface circuit.Can know that these circuit all can be selected for use according to actual needs, can select one or more for use.
Further, described current-voltage sampling circuit 101 can adopt constantan wire and resistor voltage divider circuit the sample momentary current and the voltage of 220V alternating current used in everyday, if electrical appliance has adopted other voltage, just according to different magnitude of voltage adjustment sample resistances.According to the rated power of different electrical appliances, adjust different current sampling constantan wires in addition, with the electric current after guaranteeing to take a sample and magnitude of voltage in the input range of signal processing circuit 102 permissions.

Calculate with whole nation generating mark consumption of coal 342 gram/degree in 2009:
1, reaction equation: C+O2=CO2
2, condition: mark coal constituent content 85% (weight); C molecular weight 12; CO2 molecular weight 44, then the carbon dioxide of every kilowatt-hour generation is: 342 grams * 0.85/12 * 44=1065.9 gram
According to another statistics China gross generation in 2009 is 34,334 hundred million degree, and wherein the thermoelectricity generated energy accounts for 82.6%, water power 16.6%.All the other 0.8% are nuclear power, wind-powered electricity generation, sun power etc.Because water power, nuclear power, wind-powered electricity generation, sun power directly do not discharge CO2 in power generation process, so our institute's electricity consumption can be converted to the equivalent emission amount of carbon dioxide of electricity consumption, the i.e. CO2 of kilowatt-hour discharging=1065.9 gram * 82.6%=880.4334 grams according to 82.6% ratio.Adopt this coefficient to multiply by power consumption and just can obtain the carbon emission amount that this electrical equipment is worked within a certain period of time and produced.Originally the measurement display device that is embodiment has adopted the mode of greenhouse gases (carbon dioxide) discharge capacity of general in the world demonstration climate warming to come the effect of visual representation reduction of discharging first, not only showed energy-saving effect, also shown simultaneously the effect that reduces discharging, for applying for that later on CDM (CleanDevelopment Mechanism, Clean Development Mechanism) lays the foundation.This coefficient can upgrade at any time, for example uses official's data instead.
The following describes the principle of work of the measurement display device of present embodiment.
Current-voltage sampling circuit 101 reads the input end current and voltage signals of alternating current of the 220V of various electrical appliances, and this signal is delivered to D/A converting circuit 1021 in the signal processing circuit 102.In central processing unit circuit 1023, finish the calculating of the carbon emission amount related data of instantaneous power, electric weight, corresponding conversion, the data of the date Hour Minute Second of the correspondence that these data read from real time clock circuit 1022 together with central processing unit circuit 1023, write together in the data storage circuitry 1025 and preserve, energy-conservation preparing with power mode formulated in statistical study after being used for.Simultaneously again with these data at display circuit 103, be generally liquid crystal display, middle employing is rolled or fixing mode shows.Parameter setting circuit 104 be used for the operator set in this locality the current/voltage threshold value, regularly start-up time, set clock, communication format or the like parameter.In addition, central processing unit circuit 1023 is also constantly monitored the current/voltage of input, and compare with the current/voltage threshold value of setting, to start warning circuit 106 and go out sound and light alarm if find to exceed or be lower than threshold value, and also can finish cut-out electrical appliance power supply or predetermined operations by control circuit 105 simultaneously according to the program of original setting.If it is normal to postpone a period of time system recovery, energized is resumed work again.Just strengthen the security of electrical appliance in this way greatly, eliminated the potential safety hazard of overcurrent, overvoltage.As required can also be by communication interface circuit 107 with the type that breaks down, the time of breaking down reports administrative center.
Need to prove, measurement display device of the present utility model can be built in general industry or the civilian power device, as air-conditioning, refrigerator, electromagnetic oven, the industrial electro heating furnace, Power conversion board etc., be used for measuring and be presented at the instantaneous electric current of electric process, voltage, instantaneous power, the power consumption of accumulative total and the carbon emission amount (being CO2 emissions) of conversion, point out the present power device of user whether to be in the running status of working the most efficiently by this method, the carbon emission amount of electric energy that makes the efficient of the real-time perception power device of user and consumed and equivalence, thereby impel the user with they consumption habit and consumption mode become more efficient, environmental protection more, reach the purpose of energy-saving and emission-reduction, also saved spending simultaneously for the user.
For have in the factory many same, and ruuning situation equipment too, their power consumption should be the same.If installed this measuring apparatus additional, just can in time find the situation that those reasons owing to maintenance or fault cause power consumption to increase by the energy consumption data that compares between them, thereby eliminate safe hidden trouble, raise the efficiency.
