Accurately, reliably.
During the electric energy meter detection method of the present invention is used for into detection device of electric energy meter, on the basis of above-described embodiment
On, in other embodiment, referring to Fig. 2, step S11 includes：
Step S100, count respectively the first number of samples of rising edge of a pulse in one pulse period of pulse signal,
The second number of samples, the 3rd number of samples of pulses low and the 4th number of samples of pulse high level of pulse falling edge.
Specifically, it can be seen from above-described embodiment, a pulse period includes rising edge, high level, trailing edge and low electricity
Flat, in the present embodiment, one pulse period pulse of statistics is in sampled point number during rising edge, and is used as the first number of samples
Preserve, statistics pulse is in sampled point number during trailing edge, and is preserved as the second number of samples, and statistics pulse is in low electricity
Sampled point number usually, and preserved as the 3rd number of samples, statistics pulse is in sampled point number during high level, and makees
Preserved for the 4th number of samples.
Step S101, the ADC values of all sampled points of pulses low are obtained, and it is cumulative cumulative to obtain the first ADC values
Value；The ADC values of all sampled points of pulse high level are obtained, and are added up to obtain the 2nd ADC value accumulated values.
Specifically, in the present embodiment, can be sampled by ADC (analog-digital converter) pulse signals, and common ADC
There are 8,12 or 16, illustrated by taking the ADC of 12 as an example, herein, this 12 are indicated with binary system, therefore, should

Referring to Fig. 3, step S12 includes：
Step S200, obtain sample rate and scale conversion coefficient.
Specifically, sample rate and scale variation coefficient are obtained, the sample rate is the frequency of sampling, sets the sample rate as f,
Then the time interval between every two neighboring sampled point is 1/f, and when being sampled, there can be error, for example, pulse signal
When entering high level state by rising edge, first sampled point sampled to high level state may be not on by rising
Edge enters in the flex point of high level state, therefore the actual pulse parameter for causing finally to calculate has certain error, in order to the greatest extent may be used
The error can be reduced, it is therefore desirable to high-speed sampling, then the sample rate f should set a larger value, and sampling speed is improved with this
Degree, reduce sampling error.The conversion relation of the scale conversion coefficient between AD digital quantities and survey engineering amount, such as AD numerals
Amount 1000 represents actual 20V voltage, then scale conversion coefficient is exactly 0.02.

Calculate pulse high level electric current.
Wherein, pulse rise time, pulse fall time, pulses low time, pulse high level time, the low electricity of pulse
Ordinary telegram stream and pulse high level electric current composition actual pulse parameter group.
Specifically, first number of samples is set as N1, pulse rise time T1, then pulse rise time T1=(1/
f)*N1；Similarly, the second number of samples is set as N2, pulse fall time T2, then pulse fall time T2=(1/f) * N2；
Set the 3rd number of samples as N3, pulses low time be T3, then pulses low time T3=(1/f) * N3；Set the 4th
Number of samples is N4, the pulse high level time is T4, then pulse high level time T4=(1/f) * N4.It is tired to set the first ADC values
Value added is S1, and scale conversion coefficient is C, pulses low electric current is I1, then pulses low electric current I1=(S1*C)/N3；If
Fixed 2nd ADC value accumulated values are S2, pulse high level electric current is I2, then pulse high level electric current I2=(S2*C)/N4.By upper,
It is low to calculate pulse rise time T1, pulse fall time T2, pulses low time T3, pulse high level time T4, pulse
Current levels I1 and pulse high level electric current I2.
In the present embodiment, after calculating the actual pulse parameter group, each actual pulse parameter is entered respectively
Row judges that if exceeding predetermined pulse parameter area in the presence of any one parameter, the electric energy meter is unqualified, only when all actual arteries and veins
When rushing parameter and each falling within corresponding predetermined pulse parameter area, the electric energy meter is qualified.By judging multiple actual arteries and veins
Parameter is rushed to determine whether electric energy meter is qualified, the judged result degree of accuracy is higher.
During the electric energy meter detection method of the present invention is used for into detection device of electric energy meter, in order to prompt user finally to sentence
Disconnected result.Therefore,, will each actual arteries and veins as shown in figure 4, step S13 in other embodiment then on the basis of above-described embodiment
