PROBLEM TO BE SOLVED: To add the function of detecting the traveling direction of a train to a railroad crossing controller.SOLUTION: A direction detection adapter 100 independently detects a train based on a track transmission signal output by a railroad crossing controller 1, and detects a traveling direction of the train by using a difference (along the traveling direction of the train) between a train detection section covered by the direction detection adapter 100 and a train detection section covered by the railroad crossing controller 1. Specifically, if a train is first detected by the direction detection adapter 100 and then by the railroad crossing controller 1, it is determined that the train is traveling in a direction from a transmission-side installation point toward a receiving-side installation point (a first direction). In contrast, if a train is first detected by the railroad crossing controller 1 and then by the direction detection adapter 100, it is determined that the train is traveling in a direction from the receiving-side installation point toward to the transmission-side installation point (a second direction).SELECTED DRAWING: Figure 1
【課題】踏切制御子に列車の進行方向を検知する機能を追加することを可能にする。【解決手段】方向検知アダプタ100は、踏切制御子1が出力する軌道送信信号に基づいて、独自に列車の検知を行い、方向検知アダプタ100による列車検知区間と、踏切制御子1による列車検知区間との(列車の進行方向に沿った)ずれを利用して、列車の進行方向を検知する。すなわち、まず、方向検知アダプタ100によって列車が検知された後に、踏切制御子1によって列車が検知された場合は、送信側取付点から受信側取付点に向かう方向(第一方向)に列車が進行していると判断し、一方、まず、踏切制御子1によって列車が検知された後に、方向検知アダプタ100によって列車が検知された場合は、受信側取付点から送信側取付点に向かう方向(第二方向)に列車が進行していると判断する。【選択図】図1
