The Operational Control Center (OCC) to the transportation system is like the brain to the human body which carries commanding, controlling and other important roles. The TIAA MRT OCC is located in Chingpu Depot and comprised two major systems, the signaling control system and Supervisory Control and Data Acquisition System (SCADA). The two systems are responsible for integrating the remote control and monitoring of all subsystems, making it the most important monitoring and management center for the entire TIAA MRT System.
The OCC system includes: monitoring equipment such as signals, platform door, power supply, communication, flight information display, station and depot building management system, etc. In addition, personnel configuration in the OCC includes duty manager, operational information assistant, route controller, equipment monitors and so on.
SCADA has remote monitoring and data capture function that can monitor and manage related equipment of the above-mentioned systems. The feedback and warning messages from on-scene equipment can also be transmitted back to the control personnel in the OCC, acting as reference for terminal command. Then, the control command issued by the duty manager will be conveyed to the relevant station equipment.
From the design evolution of domestic MRT SCADA system integration and linkage demands are on the rising trend in the range of safety management. In addition to the original monitoring function, the SCADA has combined with remote control, making it even more important. For instance, the SCADA of Kaohsiung MRT focuses on monitoring, so the SCADA is placed under the communication system. It is managed by the OCC and collects the signals from stations and depots in order for the personnel of the OCC to grasp the status of the TIAA MRT System and control various subsystems in the communication system. The TIAA MRT System realized the remote control function which included the E&M, station access, tunnel lighting, tunnel ventilation, smoke system, fire alarm system and many other system signals in the SCADA. The OCC holds the remote control power.
Through integration of system signals by SCADA, the OCC can either grasp real-time status or remote control the system. The functions are realized in response to the occurrence of a sudden or abnormal incident to quickly link between different systems according to the SOP and effectively achieve the purpose of safety management.
