Custom HT antennas + railway ladle ID
01
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.
02
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.
01Radomes facing heat and splash cap system life
02Consecutive wagons trigger heavy RFID cross-reading
03Open-track weather and vibration demand extreme reliability
03
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 antenna
Splash-resistant radome rated 250℃, lifetime matched to the ladle campaign
Railway readers
Narrow-beam trackside antennas read wagon by wagon with radar-triggered windows
Principle-level anti-collision
Physical coding of EMMA chips rules out adjacent-channel cross-reading
Maintenance-free design
Passive and battery-free: install and forget, even in open-track environments
04
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
05
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.
