A radio frequency identification positioning method for smart meter warehouse management

Abstract

The invention relates to a radio frequency identification and positioning method for intelligent ammeter storage management. The method comprises: (1), a reader arranged at a boundary of a warehouse collects an energy intensity of a to-be-localized intelligent ammeter in a warehouse monitoring area and an energy intensity of a virtual reference tag arranged at a vertex of an equally-divided grid in the warehouse monitoring area; (2), virtual reference tag samples adjacent to the to-be-localized intelligent ammeter are determined; (3), according to memberships to the energy intensities of the virtual reference tag samples by the to-be-localized intelligent ammeter, a virtual reference tag sample closest to the to-be-localized intelligent ammeter is determined; (4), the energy density of the virtual reference tag sample closest to the to-be-localized intelligent ammeter is determined; and (5), the location of the to-be-localized intelligent ammeter is determined. The method has characteristics of high positioning precision, low complexity, low cost, and low energy consumption.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification applications, in particular to a radio frequency identification positioning method for storage management of smart meters. Background technique [0002] With the reform of the national power industry and the planning and construction of smart grids, in order to ensure the national strategic energy security and the lifeline security of the national economy, the management level of power assets is gradually improving, and the management mode of power metering and storage has also undergone major changes. Intelligent storage management The application of the system in the storage management of electric energy meters has improved the quality of electric energy meter storage management and paved the way for the construction of a first-class electric power intelligent storage logistics center. The smart meter warehouse management system is a system that manages information, resour...

For this reason, a multi-reader fan-shaped overlapping model is proposed, but the requirements for the configuration and quantity of the readers themselves are relatively high, and the cost increases significantly

And because the reader can simultaneously display the value of the arrival phase while receiving the signal strength of the tag, and the superposition noise of the arrival phase is additive and easy to filter out, so an indoor positioning algorithm using POA is proposed, but when the frequency of the transmitted signal is too high, the measured range will be limited
