Full life circle traceable electric energy meter based on wireless technology

Abstract

The present invention provides a full life circle traceable electric energy meter based on the wireless technology, belonging to the electrical device field. The electric energy meter is provided with a memory device which is internally provided with error values corresponding to the electric energy meter, the memory device receives energy through the wireless power supply mode, the memory device is internally provided with parameter values including the error values, and the parameter values comprise timestamp corresponding to the error values, the stage body numbers of the electric energy meter, the manufacture factory numbers and the check position. The full life circle traceable electric energy meter based on the wireless technology performs reading-writing operation of the parameter values in the memory device of the electric energy meter and performs public and private key signature authentication management of the device participating in the write operation to ensure the authority of the parameter values in the memory device so as to realize the analysis of the error recording of the electric energy meter according to the parameter values an provide a good basis for the reliability consideration of the electric energy meter.

Description

Technical field [0001] The invention belongs to the field of power equipment, and particularly relates to a full life cycle traceable electric energy meter based on wireless technology. Background technique [0002] The initial appraisal record of the electric energy meter is often required during on-site calibration to analyze whether the electric energy meter has problems such as error drift, so as to facilitate the analysis of faults in advance, eliminate the fault meter, and reduce the loss of users and grid companies. However, due to historical management problems, a large part of the power bureaus cannot find the original maintenance records of the electric energy meters. Summary of the invention [0003] In order to solve the shortcomings and deficiencies in the prior art, the present invention provides an electric energy meter capable of reading and writing key parameters through wireless communication. [0004] In order to achieve the above technical objectives, the presen...
