應用雷達波建構穿越平交道之安全警報系統

Application of Doppler Radar on the Construction of Railroad Crossing Security Alarm System

摘要


本文利用以雷達波感測振動之裝置,偵測有限區域內之振動訊號,其原理使用雷達都卜勒感測方法,將分析擷取到之振動訊息(即頻率與振幅大小),分辨該振動訊號為人或列車之訊號,得到此微振動的辨別關係後,將訊號送出給管制中心或列車駕駛,達到列車減速或停止,以防止災害發生。本技術之關鍵在於夜間或視線不良,列車通行軌道管制區時可提供安全監控,且使用自行開發之軟硬體,除操作上更方便亦可提供客戶客製化的規格要求。透過小型模擬軌道管制區之安全警報裝置的振動訊號分析,說明此雷達感測裝置應用於穿越軌道之安全系統是可行且值得推廣。

The radar as a vibration sensing device in this paper for the vibration detection of a limited area, within which the vibration signal is detected using doppler radar sensors, is able to analyze the captured vibration signals (ie, frequency and amplitude), to distinguish the signals of human or train, and then send such distingwished micro-vibration signal to the control center or moving train to slow down or stop the train in order to prevent disasters. The measuring method is described along with results of the practical implementation study. The feasibility of further radar application is also discussed.
