Method for verifying functions of intelligent electric energy meter based on genetic algorithm

Abstract

The invention discloses a method for verifying functions of an intelligent electric energy meter based on a genetic algorithm. The method comprises the steps: setting to-be-verified events of the intelligent electric energy meter and power parameters involved during the verification of the functions of the intelligent electric energy meter according to the actual needs, obtaining a triggering condition of the to-be-verified events, and then obtaining the value range of each power parameter according to the triggering condition; taking each source adjustment parameter vector as an individual chromosome, and sequentially obtaining each source parameter vector through the genetic algorithm, wherein the fitness value of each individual is a number of to-be-verified events trigged by the corresponding source adjustment parameter vector; finally, setting the power parameters of the intelligent electric energy meter according to the source adjustment parameter vectors to realize the verification of the functions of the intelligent electric energy meter. The method can automatically generate the required source adjustment parameter vectors of the function verification of the intelligent electric meter, can complete the verification of all the to-be-verified events by using a small number of source adjustment parameter vectors, can reduce the workload of a tester and improve the verification efficiency of the functions of the intelligent electric energy meter.

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
