Abstract

The invention discloses a method for improving the reliability of a radio-frequency identification tag of a low-voltage mutual inductor based on experience modal decomposition, and the method comprises the steps: measuring the performance data of the radio-frequency identification tag of the low-voltage mutual inductor under the factors of different temperature, humidity, mutual inductor coil electric quantities and electromagnetic interference intensities, and building a basic expert database of the radio-frequency identification tag of the mutual inductor; measuring the data of the radio-frequency identification tag of the low-voltage mutual inductor in a normal environment, and building a normal database of the radio-frequency identification tag of the low-voltage mutual inductor in the normal environment; measuring the data of the radio-frequency identification tag of the low-voltage mutual inductor in an on-site environment, and building an on-site database of the RFID(radio-frequency identification) tag of the low-voltage mutual inductor in the on-site environment; and carrying out the analysis of the built basic expert database, normal database and onsite database based on an error analysis method based on the EMD (Empirical Mode Decomposition).

Description

technical field [0001] The present invention relates to an empirical mode decomposition method, and more specifically, relates to a method for improving the reliability of RFID of a low-voltage transformer based on empirical mode decomposition (EMD). Background technique [0002] RFID (Radio Frequency Identification) is radio frequency identification technology, also known as electronic tags and radio frequency identification. optical contact. The RFID system is mainly composed of electronic tags, card readers and antennas. The electronic tags include electromagnetic induction coupling devices and chips that store identity information. At this stage, there are also some RFID-related applications in the power system, such as line inspection, metering box anti-theft electricity, substation inspection, switch cabinet inspection, energy meter prepayment, etc. However, this type of radio frequency tag is often oriented to general-purpose asset management applications, and its f...
