Embodiment approach
[0060] It should be noted that in practical applications, the output pulses of the electric energy meter can also be output to the detection instrument, and then the detection instrument completes the counting and analysis. In this implementation manner, the above-mentioned control device for quick detection of electric energy meters further includes a meter interface, which is used for connecting a detection meter. Processors are used to:
[0061] Control the detection process of the detection instrument through the instrument interface;
[0062] While modifying the pulse constant of the electric energy meter, modify the pulse constant of the detection instrument to be the extended value of the pulse constant;

The invention discloses a rapid detection method and device of an electric energy meter. The rapid detection method of the electric energy meter comprises the steps that S1, a pulse constant extension value is determined according to a detecting point and parameters of the electric energy meter; S2, detection is carried out after a pulse constant of the electric energy meter is modified into the pulse constant extension value. After the pulse constant of the electric energy meter is modified, an electric energy number represented by each pulse is reduced, output pulses are accelerated under the condition of small signal current, the detection speed under the condition of small signal current is improved, further the detection efficiency of the entire electric energy meter is improved, and finally the production efficiency of the electric energy meter is improved. When the rapid detection device of the electric energy meter is used for detecting the electric energy meter, the electric energy number represented by each pulse is smaller, and therefore the sensitivity of the electric energy meter is detected while accuracy is detected.
Description
technical field [0001] The invention relates to the detection of electric energy meters. Background technique [0002] As an electric energy metering device, the electric energy meter is widely used in various aspects of the national economy and people's livelihood. At the end of the production process of the electric energy meter, the electric energy meter needs to be tested: if the error of the electric energy meter is within the specified standard range, the electric energy meter is a qualified product; otherwise, the electric energy meter is a substandard product and cannot enter the sales process. [0003] When the electric energy meter is tested, it is necessary to set up multiple detection points for detection respectively, and the current of each detection point is different. If the errors of the electric energy readings measured by the electric energy meter under various current environments are within the specified range, the electric energy meter is a qualified p...
