Method for identifying data of electronic label on truck in high speed

Abstract

A method for identifying electronic countermark of high speed freight train includes embedding compiled program into relevant program of reader / writer, coordinating embedded program with hardware for timely collecting relevant information in electronic countermark on freight train and up-transmitting collected information to control center.

Description

technical field

[0001] The invention relates to a method for identifying data of an electronic tag, in particular to a method for identifying data of an electronic tag for a high-speed truck. Background technique

[0002] As we all know, after a truck electronic tag is activated by the microwave signal emitted by the reader, it will continuously and repeatedly return the data frame in the tag. The tag data frame consists of frame header and data (128 bits), which is the relevant data information of the train stored in the electronic tag. When the train is running at a slow speed, the signal returned from the electronic tag at the bottom of the train to the reader is less affected by the multipath effect. The reader can detect the signal returned by the tag in time and accurately, and interpret the data in the tag. Once the train speed exceeds 80 km / h, the multipath effect is greatly affected, and the signal returned from the train electronic tag to the reader hardly has a c...
