Taipei Rapid Transit Corporation (TRTC) was established in 1994 as Taiwan's first company specifically responsible for the operation of a rapid transit system. In 2004, Taipei Metro achieved an impressive average of 1.508 million car-kilometers between every delay of five minutes, making Taipei Metro number one in reliability among all Nova International Railway Benchmarking Group (Nova)/CoMET members according to data from London Imperial College's Railway Technology Strategy Centre (RTSC). Taipei Metro also has held this title for four years in a row.

To enhance safety and service quality, Taipei MRT planned to upgrade surveillance system on their Danshui-Xindian mass transit line in 2010. The project required a suite of industrial networking and computing products that fully complied with IEC 60571 to guarantee the reliable operations.

• IEC 60571 compliant networking and computing devices with vibration and shock resistant design
• The powerful and reliable industrial computers for seamless integration with communication backbone and video surveillance system
• High system performance for video recording and playback
• Fanless design for reliable system operation

Taipei MRT required powerful and reliable industrial computers that is able to seamless integrate with communication backbone and video surveillance system. Moxa's IEC 60571 compliant networking and computing devices were selected to create on-board Network Video Recording (NVR) systems.

Moxa's TN-5516 Ethernet switches were deployed throughout whole metro to build up an IP-based communication backbone. The system operator used its port-trunking function to enable wider bandwidth. With TN-5516, up to eight ports can be assigned to one trunk group to optimize network connections and create redundant paths for critical POS (passenger-oriented system). The MC-4615-C23 computers were deployed in the driver's cab and perform real-time monitoring and playback of the images transmitted from the cameras. These images can also be recorded by the MC-4615-C23 computers. From the display located in the driver's cab, the driver can monitor and play back the images from the selected cameras. In addition, V2416 computers in each passenger car are responsible for monitoring and recording the images from the cameras, allowing the driver to simultaneously view the entire train.

Vibration and shock is a constant concern for rolling stock applications. All of Moxa's selected products are equipped with M12 connectors and offers fanless design reducing the number of potentially unreliable moving parts allowing reliable metro onboard applications.

 

• Wide selection of IEC 60571 compliant industrial networking and computing products
• Moxa has successful reference sites for railway onboard communications around the world
• High performance and reliable system to operate onboard surveillance application
• Fanless hardware design to ensure reliable operation on metro
