| Abstract |
This paper proposes a new position detection method for train speed control using the Phase Difference of Arriving. This method aims to apply to Automated Guide-way Transit systems, to be operated without driver. So it is absolutely required to range, calculate and decide a train position precisely. This system consists of Vehicle Radio Set(VRS) and Wayside Radio Set(WRS). The VRS transmits a wireless signal to the WRS and the controller calculate a straight line and curve line with Phase Difference of Arriving(PDOA) and an exact position using track date-base is calculated at next step. |
