High-speed rail train wheel RFID one-stop intelligent maintenance

By the end of 2020, China's railway operating mileage will reach more than 146,000 kilometers, including 38,000 kilometers of high-speed rail, ranking first in the world. China's high-speed rail is a dedicated passenger railway line with a designed operating speed of more than 250 kilometers per hour (including reservations) and an initial operating speed of more than 200 kilometers per hour. From 2010 to 2020, China has built a high-density high-speed railway network in urban agglomerations in the Yangtze River Delta, Pearl River Delta, Bohai Rim and other regions, and completed high-speed rail interconnection between the four major regions of the east, central, west and northeast. It greatly improves the comfort and efficiency of people's travel. The one-stop intelligent RFID solution for high-speed train wheels provides the railway department with safe and reliable intelligent inspection of wheels and rails, improving work efficiency.

For high-speed trains traveling at speeds above 250 kilometers per hour, the wheels are important components to ensure driving safety. As wheels with extremely serious daily wear and tear, their single operating life is basically half a year. Wheels are divided into level one maintenance to level five maintenance. EMUs and high-speed rail locomotives need maintenance after running for 4,000 kilometers or 48 hours. According to the operating speed and mileage of high-speed rail, maintenance is required almost every day.

When the mileage of a high-speed train reaches 30,000 kilometers, the train needs to be taken off the line and put into storage for repairs. Secondary maintenance is required every 10 days. Every time a worn patch is replaced, it needs to be photographed and recorded with a camera, and the patch needs to be recycled for processing. Each operation requires leaving image data. Maintenance personnel usually carry a small record book with them to record in detail the types of replacement parts, maintenance content, maintenance time, and maintenance personnel.

Through cooperation with high-speed rail strategic system integrators, it provides relevant railway departments with a one-stop solution for safe, reliable, stable and intelligent high-speed rail train wheels. The high-speed rail RFID tag uses the latest Qstar-56 USER area 2Kbits chip to ensure the rapid reading and writing of a large amount of offline information; at the same time, due to the huge centripetal force generated during the operation of the locomotive, the special mechanical design structure of the bolt allows the bolt to operate without affecting the strength of the body. Under the conditions to ensure the safe and stable placement of labels.

The staff performs regular maintenance, and a large amount of information for each maintenance is Stored in the Qtag-5601 tag, which communicates with the reader through radio frequency technology and accesses and stores the cloud backend database. The time it takes for a unit to complete wheel maintenance has been reduced from 8-10 minutes to 2 minutes. It greatly reduces the work pressure of inspection personnel and improves the accuracy and efficiency of maintenance work.
