And recording the current data of the intelligent electric meter to be detected after the circuit is completely disconnected.
S20, connecting the measuring equipment to the household circuit, and recording the data of the intelligent electric meter after the specified time;
it can be understood that, in the case that other electric devices in the circuit are completely disconnected, the power consumption of the measuring device at this time can be regarded as the power consumption of the whole circuit.
And S30, obtaining the difference between the power consumption data of the measuring equipment and the data of the intelligent electric meter, and judging whether the metering of the intelligent electric meter is accurate or not based on the power consumption data and the data difference.
It can be understood that there are various ways to obtain the power consumption data of the measuring device, and this embodiment lists three relatively suitable ways.
The first method is as follows: the measuring equipment is an electric appliance with known rated power, and power consumption data of the measuring equipment is obtained according to the rated power multiplied by the specified time.
Generally, the rated power or rated voltage and rated current of the household electrical appliance are written on a plug or a specification of the household electrical appliance, and if the rated voltage and the rated current are written, the rated power is equal to the rated voltage multiplied by the rated current.
Meanwhile, in this embodiment, at least one timing device is further required, when the measurement device is connected to the circuit, the timing device starts timing, when the measurement device is disconnected from the circuit, the timing device stops timing, the time difference of the timing device is the designated time selected in this embodiment, and preferably, the designated time is greater than or equal to 1 hour and less than or equal to 3 hours, so that the influence of the increase of the actual power on the determination result is reduced.
And finally, multiplying the rated power by the specified time to obtain power consumption data of the measuring equipment. Preferably, the rated power is in kilowatt, and the specified time is in hours, that is, the finally obtained power consumption data is in kilowatt-hour.
Further, the difference between the actual power and the rated power is deeply considered, namely, the difference between the finally calculated power consumption data and the actual power consumption data is considered, so that one twentieth of the power consumption data value calculated according to the rated power is taken as an error range, and if the difference between the power consumption data calculated according to the rated power and the data difference of the intelligent electric meter is smaller than or equal to the error range, the metering accuracy of the intelligent electric meter is judged.
Square two: the measuring equipment is an intelligent electronic product capable of obtaining the data of the intelligent electric meter through networking, such as a mobile phone, a tablet or a notebook. And the data of the current intelligent electric meter and the data of the intelligent electric meter after the appointed time are both obtained through the intelligent electronic product. And the intelligent electronic product is also provided with a charging energy consumption detection APP, and after charging is completed, the power consumption data of the measuring equipment is obtained according to the data displayed by the charging energy consumption detection APP.
It can be understood that the charging power of a smart phone or tablet is usually 20w to 50w, and when the smart phone or tablet is fully charged, the smart meter usually consumes 0.015 to 0.04 degrees of electricity, so that the method is more suitable for detecting some smart meters with the metering accuracy of 0.01 kilowatt-hour, namely, two bits after the decimal point of the smart meter reading (only one bit after the decimal point of the common smart meter). Of course, a plurality of APP intelligent devices with charging energy consumption detection can be charged simultaneously, and finally data displayed on the APP can be added, so that the common intelligent electric meter can be checked as long as the accumulated power consumption is greater than 0.1 degree.
By the method, the smart meter can be checked more intuitively. Meanwhile, the intelligent equipment also belongs to common electronic products at present, and the method also meets the application requirement of most common users.
The third method comprises the following steps: the measuring equipment is selected from an electric energy meter and an electric appliance, the electric appliance is connected with the electric energy meter and then is connected with the household circuit, and the power consumption data of the measuring equipment is obtained according to the reading on the electric energy meter.
In this way, the electric appliance can be a common power consumption device, and the electric appliance is preferably a household high-power electric appliance in consideration of the reasons of error and convenient comparison; the electric energy meter can be a common electric energy metering device bought in the market or a socket with an electric energy metering function, the electric appliance is connected with the electric energy meter and then connected into a circuit, and the electric energy meter is used for measuring the power consumption data of the electric appliance.
It will be appreciated that this method, compared to the previous method, does not require the intelligence of the appliance and is not affected by the difference between the actual power and the rated power.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
