Custom HT antennas + railway ladle ID

IndustrySteel · Rail transport LocationWuan, Hebei / Jiujiang, Jiangxi YearIn operation

Overview

For railway hot metal, we developed HT antennas whose radomes endure molten splash and 250℃ long-term; railway ladle ID runs maintenance-free for the campaign life with zero cross-reading.

Challenges

Rail transport brings dust, weather and vibration; antennas face direct heat radiation so ordinary radomes fail fast; and conventional RFID cross-reads as wagons pass in sequence, scrambling ladle IDs.

Radomes facing heat and splash cap system life
Consecutive wagons trigger heavy RFID cross-reading
Open-track weather and vibration demand extreme reliability

Solution

Fix it at both levels: custom HT antennas keep hardware alive, narrow-beam railway readers with principle-level anti-collisions keep reads correct, and passive design keeps cost of ownership near zero.

Custom HT antennaSplash-resistant radome rated 250℃, lifetime matched to the ladle campaign
Railway readersNarrow-beam trackside antennas read wagon by wagon with radar-triggered windows
Principle-level anti-collisionPhysical coding of EMMA chips rules out adjacent-channel cross-reading
Maintenance-free designPassive and battery-free: install and forget, even in open-track environments

Deployment Scope

HT antenna development incl. radome and structure
Trackside reader stations and trigger radars
Anti-collision calibration and multi-wagon tests
Cold-weather validation and long-term O&M plan

Results

The HT antennas have run maintenance-free from day one with zero cross-read events; reading rates hold in bad weather, fully replacing manual ID and fragile labels.
