Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The embodiment of the present invention is a method for determining the consistency of the mechanism of the smart meter. Currently, there is no matching method specially developed for the smart meter in the market. The embodiment of the present invention fills the gap in this respect. The existing enhanced test data of smart electric meters is less, and it is difficult to analyze them more accurately by traditional data processing methods. The method of gray theory in the embodiment of the present invention can be used in the case of small samples and poor information, which makes up for the traditional methods in Pitfalls when dealing with hardened test data.

[0026] Such as figure 1 As shown, the flow chart of the method for determining the multi-stress...

Abstract

The invention discloses a multi-stress limit determination method for an intelligent ammeter. The method comprises the following steps: determining the sensitive stress of the intelligent ammeter through FMEA (Failure Mode and Effects Analysis); respectively setting the stepping reinforcement stress tests of both temperature and electric stress; testing the output characteristics of the intelligent ammeter; processing the test result; and determining the mechanism consistency condition. The method provided by the invention is specially for determining the mechanism consistency of the intelligent ammeter and makes up the blank that a matched method specially researched and developed for the intelligent ammeter is unavailable in the present market. The conventional reinforcement test data of the intelligent ammeter is less, and can not be analyzed more accurately by adopting a traditional data processing method. The grey theory method provided by the invention can be used under the small-sample poor-information condition, thereby compensating defects when the reinforcement testing data is processed by the traditional method.

Description

technical field [0001] The invention relates to the smart meter technology, in particular to a method for determining the multi-stress limit of the smart meter. Background technique [0002] Smart meters are intelligent instruments with microprocessor application and network communication technology as the core. They have the capabilities of automatic metering / measurement, data processing, two-way communication, and function expansion. Functions such as multiple electricity price billing, remote power supply interruption, power quality monitoring, water and gas heat meter reading, and user interaction are responsible for the collection, measurement, and transmission of raw energy data. Foundation. Since smart meters are still in the promotion stage in China, many reliability problems have been exposed during use, and research in this area is still very weak. [0003] To study the reliability of smart meters, an effective method is to conduct accelerated tests on them. A p...
