Railway vehicle number identification system and information transmission method

Abstract

The invention discloses a railway vehicle number identification system and an information transmission method and aims to solve the technical problem of improving the identification rate of an electronic tag of the railway vehicle number identification system. The system consists of an electronic tag programmer, an electronic tag, an electronic tag reader antenna, an electronic tag reader and an upper computer. The method comprises the following steps that: the electronic tag programmer carries out FMO (Flexible Macroblock Ordering) programming on the electronic tag and encoded data is written into a storage; the electronic tag reader transmits carrier waves to irradiate the electronic tag and the electronic tag reflects the data in the storage; the electronic tag reader receives a reflection signal and the reflection signal is demodulated; and FMO decoding is carried out to obtain tag data. Compared with the prior art, due to the adoption of the FMO decoding, the equivalent transmission rate of the tag information in the process of identifying the tag is improved by 4 times, the frequency of transmitting data frames between the reader and the tag is improved, the effective information transmission rate is improved, and the highest adaptation vehicle speed of the electronic tag reaches over 300km per hour.

Description

technical field [0001] The invention relates to an encoding and decoding system and method of an electronic label, in particular to an encoding and decoding system and method of an electronic label applied to high-speed railway car number identification. Background technique [0002] The railway car number identification system based on radio frequency identification (RFID) not only improves the management level of my country's railway vehicles to the current international advanced level; it also plays a huge role in the automatic tracking, scheduling and management of railway locomotives and freight cars. It eliminates accidents of wrong number and double number of railway wagons; it becomes the data basis for wagon fee settlement in railway transportation management, and significantly improves the punctuality rate of trains. It can be seen that the railway car number recognition system has become an all-weather operating equipment in the production management of railway tra...

AI Technical Summary

Problems solved by technology

In the prior art car number recognition system using "deformed FSK (AAR) coding" technology, the maximum speed of railway electronic tags is 128 km / h. Therefore, the electronic tags of high-speed locomotives with a speed of 128km / h or more cannot be reliably identified, resulting in the identification rate of locomotives and trains not meeting the application requirements.
