Have a safe and pleasant journey starting with PoE system
背景
鐵路是一令人種愉悅的交通方式，讓旅客方便、舒適地從一個地方到另一個地方旅行。然而，乘客在火車站或月台上的安全是首要考量，這使得安全監控成為鐵路管理人員的重要任務。適當的攝像頭部署可以確保乘客的安全，防止未經授權進入受限區域，以及監控是否有乘客遺落物品。
多年來，鐵路公司已在大多數火車站部署了閉路電視系統以監視事件。然而，從2018年到2020年6月，每年仍有超過20起事故發生。鐵路是公眾方便的交通方式，但每起事故都應該仔細分析，並採取措施防止未來發生類似事件。

挑戰
- Installation: The system shall fit into a 19 inch 12U rackmount cabinet. Working under extreme temperatures, the system should operate at -20 to 70°C without a fan.
- PoE level should be higher than IEEE 802.3at, and the total power budget should be more than 480 watts.
- Bandwidth: The network devices needed to have high bandwidth and non-blocking to deliver video data, 10G uplink support is preferable.
- Management: The system must support at least Lite Layer 3 functions and even be certified with EN 50121-4.
The Network Solution: EX75900 Series
EtherWAN's EX75900 PoE Lite Layer 3 managed switch was a perfect fit for the project. The EX75900 is a hardened full gigabit managed Ethernet switch in rack-mount form factor featuring 24 ports of 10/100/1000BASE-T(X) each in compliance with IEEE 802.3bt plus 4 ports of 1G/10G SFP+ for connecting to the core network. The high density port count of EX75900 can minimize the number of switches needed for installation in order to connect with the maximum number of cameras.
The EX75900 provides a total power budget of up to 720 watts, supporting linked surveillance cameras, pan-tilt-zoom (PTZ) cameras, speed domes, and even laser cameras. The intelligent PoE functions, including Scheduling, Watchdog and Force mode, allow for comprehensive smart management of powered devices.
Conclusion
With a monitoring system backed by EX75900 deployment, unexpected events can be monitored and managed rapidly by administrators, including: platform status, left items, railway intrusion, restricted areas, and emergencies. The system not only monitors, but also completely records all events.
EtherWAN is helping to create safe and intelligent transportation areas by offering PoE systems with outstanding reliability and robustness.
