Journal Title: Urban Mass Transit - Year 2024, Vol 27, Issue 7
Abstract
Objective Targeting the inapplicability of conventional train positioning technologies to HTS (high-temperature superconducting) maglev trains, as well as the limitations of existing positioning technologies for such trains, a method based on RFID (radio frequency identification) technology for monitoring train position is proposed. Method The RFID positioning technology is introduced, and a theoretical error model for this technology in system application are proposed. The positioning software and hardware systems are designed and constructed. To improve positioning accuracy of the system, the influence of train operating speed, reader response time, and reader-tag distance on positioning errors are analyzed. On this basis, an experimental platform is established in consideration of the specific operating environment of HTS maglev trains, and the feasibility of the proposed RFID positioning method is verified. Result & Conclusion The designed RFID-based positioning method for HTS maglev trains can achieve relatively high precision positioning of maglev trains running on circular test tracks. The proposed RFID system exhibits advantages such as high reliability, low cost, and easy maintenance.
