Function Verification Method of Smart Energy Meter Based on Parameter Vector Optimization of Adjusting Source

Abstract

The invention discloses a method for verifying the function of a smart electric energy meter based on the optimization of source adjustment parameter vectors. Firstly, according to actual needs, the event to be verified of the smart electric energy meter and the power supply parameters involved in the function verification of the smart electric energy meter are set, and the trigger of the event to be verified is obtained. A condition table is used to generate a tuning source parameter vector for each event to be verified. From the generated tuning source parameter vectors, a set of tuning source parameter vectors that can trigger all events to be verified is selected to form an optimal tuning source parameter vector set. Finally, according to the optimized The source parameter vector in the source parameter vector set is selected to set the power supply parameters of the smart energy meter, so as to realize the verification of the function of the smart energy meter. By adopting the invention, the vector group of adjustment source parameters capable of verifying all events can be optimized, the workload of testers can be reduced, and the efficiency of function verification of smart electric energy meters can be improved.

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 the optimization of source adjustment parameter vectors. 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 i...

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
