- Abstract
- A train control system demands not only a high degree of safety operation, but also needs to guarantee quality service. In order to avoid a failure of the train control system, most components of train control devices are designed with redundancy. In this paper, we present a wireless communication system for LTE-R based train control which is based on a redundant method. This system consists of a railway LTE communication system (LTE-R) as the main device and a commercial LTE system as the standby device in a redundant manner. If the LTE-R system fails to communicate, commercial LTE will be replaced immediately. We developed the wireless communication hardware and software for the Korean Train Control System-3 (KTCS-3), the next generation Korean train control system. In order to measure the basic functionality and performance of this system, we evaluated the wireless communication system using a variety of scenarios.
