機場捷運中央監控系統簡介 Introduction to the Supervisory Control and Data Acquisition System (SCADA)of the TIAA MRT System
中央控制室電力-環控系統全景。

機場捷運線中央監控系統(SCADA)目的在於提供全線各車站水電環控系統(含建築物管理系統)及核心機電各系統設備之遠端監視及控制功能,並提供電聯車進入隧道區後啟動隧道通風控制之需求。中央監控系統接收各界面系統訊號,亦可依營運公司管理權責劃分需求將權限下放車站旅客詢問處(PAO)時,將部分設備訊號予以抑制。位於青埔機廠主維修廠2樓之檢閱訓練室,設置有備援之中央監控系統,以供營運單位於行控中心(OCC)須撤離時備援使用。
SCADA具有防護機制,能免受無授權之存取或控制動作。唯有具授權的系統管理員可以增加、修改或移除使用者姓名、重設密碼、建立職務設定檔或修改職務設定檔的相關權限。當系統管理員啟動更換資料庫組態時,其使用者姓名將與時間標籤皆被記錄下來。SCADA工作站提供營運操作人員有關本捷運系統所有監控設備的詳細資訊與設備故障/告警狀態。SCADA系統另將多功能終端機MFT納入監視/控制各系統設備所產生之故障或告警等訊息,每隔一分鐘提供給維修管理系統(MMS,青埔機廠之維修管理中心),MMS系統可依據蒐集之故障/告警訊息核對資料庫資訊後自動產生維修工單。
中央監控系統具有多元整合功能,透過單一平台多功能終端機運作,可協助機場捷運之核心管理中樞OCC掌握更全面的現場情報資訊,提供營運公司緊急決策,進而採取合適的應變處理方式及增加應變與救援效率。

The goal of the TIAA MRT Supervisory Control And Data Acquisition System (SCADA) is to provide remote monitoring and controlling functions of the E&M systems (including the building management system) and core E&M system equipment of the entire TIAA MRT line and to initiate tunnel ventilation when the EMU enters the tunnel. SCADA can receive signals from each interface system and can pass down authority to passenger agent offices (PAO) according to division of responsibilities of the operation company to inhibit partial equipment signals. In addition, the Playback and Training Room (PTR) on the second floor in Chingpu Depot is equipped with a backup SCADA for use of the operating unit during evacuation of the Operation Control Center (OCC).
SCADA has a mechanism to be protected from unauthorized access or operational control. Only a privileged system administrator can add, modify or remove a user name, reset password, establish job profile or modify job profile permissions. When the system administrator boots the replacement configuration database, the user name with a time stamp will be recorded. SCADA workstations provide operators with detailed information regarding all monitor equipment and failure / alarm status. In addition, the Multi-Function Terminal (MFT) of the SCADA system will be incorporated into failure or alarm messages generated by monitoring / control equipment and will be sent to the maintenance management system (MMS, Chingpu Maintenance Management Center) at one minute intervals. MMS system can automatically generate maintenance orders after verifying the failure / alert messages with database information.
The SCADA system has diverse integration abilities by operating via single platform MFT to assist the OCC of TIAA MRT to grasp more comprehensive intelligence information. The information can act as reference to the operation company in emergency decision-making and then take appropriate contingency actions to increase resilience and rescue efficiency.
