軌道異物偵測

簡介 Introductions

傳統車載端軌道偵測系統仰賴雲端運算，告警延遲常大於 5 秒，導致列車因資訊不即時而錯失煞車時機；傳統路側系統易受雜草、雨霧等因素干擾而產生誤告警，且對 20 cm 等小型異物之遠距辨識能力不足。高誤報率常導致列車行控中心難以做出即時且正確的決策。

Traditional onboard detection systems rely on cloud computing, causing alert latencies of more than 5 seconds and leading to missed braking windows. Meanwhile, conventional trackside systems are prone to false alarms from weeds or weather interference and lack the long-range resolution to identify small 20 cm obstacles. These high false-alarm rates make it difficult for Operations Control Centers (OCC) to make timely and accurate decisions.

    • Global railway sectors, including heavy rail, metro, and light rail systems.
  • 應用實例 Application Examples
    • 為有效將軌道內異物入侵狀況回報行控中心，以確保軌道車輛行車安全，本異物入侵系統已成功於桃園捷運完成場域驗證，結合車載與路側雙層防護網，透過 5G 雙模通訊將告警延遲由 5 秒大幅縮短至約 0.3 秒，為營運方爭取黃金應變時機。
    • 以超視距精準辨識技術突破人類視距與環境限制，實現全天候自動化偵測，以降低因異物入侵造成之非預期停駛損失。本產品可運用於鐵道興建及營運業者，並適用於高速鐵路、普速鐵路、捷運、輕軌等系統，有效偵測軌道狀況並提升列車行駛安全。
      • Field-validated on the Taoyuan Metro network, the system demonstrated robust performance across varied operating conditions. Its obstacle detection rate, false-alarm rate and notification latency met the field trial's 99.75% three-sigma (3σ) acceptance criteria. Integrated onboard and trackside sensing with 5G and V2X reduced detection-to-driver alert latency from over 5 s to 0.5 s, enabling earlier braking and faster OCC response. The solution supports high-speed rail, mainline rail, metro and light rail applications, helping reduce collision risks and service disruptions.
