하이브리드 궤도회로 개발의 차상안테나 설치 최적화에 관한 연구

We have studied the development of hybrid track circuits, using RFID (Radio Frequency Identification) similar to various beacons, transponder, etc. But the ultimate goal of this study is to pursue innovative cost reduction by way of minimization and simplification of equipment compared to existing equipment. Now we are under test for RFID tag recognition attached to ties by mounting onboard antenna, the RFID reader. However, because the onboard antenna location and the fixture varied according to characteristics and shapes of rail cars, we should’ve conducted the tag recognition tests by choosing installation location and height arbitrarily. As a result, we discovered that it affected to the facilities of neighboring tracks and it caused the difference of recognition rate. Therefore, in this study we present the installation plan that the recognition efficiency of tags is optimized, after we manufacture height adjustable prototypes and test them between the RFID reader and the tags in accordance with height regulation, considering the characteristics of various rail vehicles.
