機場捷運閉路電視系統介紹 Introduction to Closed Circuit Television (CCTV) in TIAA MRT System
閉路電視系統月台至列車無線電傳輸架構圖。

機場捷運閉路電視系統(CCTV)的功能係提供行控中心中央控制室(CCR)與車站控制室(SOR)的人員,監視沿線各車站及機廠,當行控中心中央控制室CCTV設備或線路發生問題,無法監看車站狀況時,車站CCTV仍可獨立運作選擇攝影機監看車站各區域影像。
在每一車站之車站控制室設置一組CCTV控制台及6個10.4吋LCD監視器、1個19吋LCD監視器,車站控制室控制員可利用安裝在工作站主機內的視頻矩陣切換器遠端圖控軟體,編程設定每個螢幕顯示的影像功能,將視頻訊號傳輸到車站控制室指定的監視器上顯示。
在青埔及蘆竹兩個機廠各設置一套獨立閉路電視矩陣切換器主機。在青埔機廠及蘆竹機廠分別設置23組及19組攝影機,其中各有4部及5部屬戶外全功能型攝影機,負責機廠廠區四周安全監視工作。
另外,車站月台的影像,以無線電傳送器傳送至列車駕駛室。當列車靠站時,設置在月台端的無線電傳送器將影像訊號傳輸至電聯車,由裝設在電聯車上的無線電接收器接收,並將訊號顯示於駕駛操作台上的10.4吋監視器上,便於駕駛員監視並確認乘客進出車廂及列車進出車站的安全。

The function of CCTV in the TIAA MRT System is to provide Operational Control Center CCR and SOR staffs the access to surveillance of each station and depot along the system lines. When the CCTV equipment or circuit in Operational Control Center CCR malfunctions, the CCTV in each station can still operate independently and monitor station areas via surveillance cameras.
In the SOR of each station, one set of CCTV, six 10.4-inch LCD monitors and one 19-inch LCD monitor are installed. The SOR controllers can program video display functions via the video matrix switch and remote graphic control software to transmit video signals to display on the designated monitor.
Both Chingpu and Luzhu Depots are equipped with one set of independent CCTV matrix switcher workstation. For Chingpu Depot, 23 sets of cameras, including four outdoor full-featured cameras, are installed for safety surveillance covering the entire depot and its surroundings. On the other hand, for Luzhu Depot, 19 sets of cameras, including five outdoor full-featured cameras, are installed.
In addition, station platform images are transmitted to the driver's cab via wireless transmitters. When the train pulls over at the platform, the platform transmitter transmits images to the EMU which is received by the wireless receiver installed on the EMU. Then, the image signals are then displayed on the 10.4-inch monitors on the driver's operation panel for the driver to ensure passenger safety during the stop.
