Function Verification Method of Smart Energy Meter Based on Genetic Algorithm

Abstract

The invention discloses a method for verifying the function of an intelligent electric energy meter based on a genetic algorithm. Firstly, according to actual needs, the event to be verified of the intelligent electric energy meter and the power supply parameters involved in the function verification of the intelligent electric energy meter are set, and the trigger condition table of the event to be verified is obtained. Then get the value range of each power parameter according to the trigger condition table; then use the source parameter vector as the individual chromosome, use the genetic algorithm to obtain each source parameter vector in turn, and the fitness value of the individual is its corresponding source parameter vector The number of events to be verified is triggered; finally, the power supply parameters of the smart energy meter are set according to the parameter vector of the source adjustment, and the verification of the function of the smart energy meter is realized. The present invention can automatically generate the source adjustment parameter vector required for the function verification of the smart electric energy meter, and can use a small number of source adjustment parameter vectors to complete the verification of all events to be verified, which can reduce the workload of testers and improve the function of the smart electric energy meter test efficiency.

Description

technical field [0001] The invention belongs to the technical field of smart electric energy meters, and more specifically relates to a method for verifying the function of an intelligent electric energy meter based on a genetic algorithm. Background technique [0002] As the main tool of electric energy measurement and economic settlement, electric energy meter is directly related to the economic interests of the country and users whether it is accurate or not. At present, all major domestic electric energy meter manufacturers mainly produce smart electric energy meters. During the production process of such electric energy meters, unqualified products will inevitably appear. At the same time, users may also have unqualified electric energy meters during use. It is a very important aspect to accurately evaluate whether the electric energy meter is qualified, so the verification of the smart electric energy meter is a very important link in the field application after it is ...

AI Technical Summary

Problems solved by technology

[0008] One is the time-consuming test plan: the current test plan requires testers to formulate one by one. For an electric energy meter with nearly 100 events, it takes about 10 minutes / item*100=1000 minutes to formulate the plan, which is about 17 hours

[0009] Second, the test time is long: as mentioned above, the test of each event is divided into three steps: parameter adjustment, source adjustment and data reading

[0010] To sum up, it takes about 8.5 working days to complete the routine inspection of an electric energy meter, and it takes about 3 days even if the inspection platform works around the clock
