Abstract

The invention discloses an electric energy meter storage failure test method based on a fuzzy test technology. The method comprises the following steps: importing an EEPROM address allocation table ofan intelligent electric energy meter into intelligent electric energy meter storage test software; the intelligent electric energy meter storage test software generating a modulus M according to theEEPROM address allocation table unit initial address and the data type; injecting M into an EEPROM data fuzzy test module of the intelligent electric energy meter; judging whether the EEPROM of the electric energy meter is consistent in access or not. The method has the advantages that the EEPROM of the electric meter is subjected to access testing through the intelligent electric energy meter storage testing software, hidden danger faults of EEPROM access in the intelligent electric energy meter are eliminated, and software faults caused by insufficient fault-tolerant capability of the electric energy meter under typical field working conditions are avoided.

Description

technical field [0001] The invention relates to the technical field of electric energy meter detection, in particular to an electric energy meter storage failure test method based on fuzzy testing technology. Background technique [0002] Since 2010, the State Grid Corporation has comprehensively promoted the construction of the electricity consumption information collection system. As of 2018, a total of nearly 457 million smart energy meters have been completed. The smart energy meter is the basic node of the "ubiquitous connection" of the ubiquitous Internet of Things, and it is also a key device to ensure the stability and reliability of power consumption measurement. [0003] The existing operating data of the smart energy meter shows that the routine testing based on technical standards can ensure the supply quality of the smart energy meter to a certain extent, but it cannot rule out the hidden faults inherent in the smart energy meter, such as: abnormal power data, m...
