Bus Network
Challenges
The current conventional train communication networks (TCN) are facing several challenges to improve the service including the limitation of bandwidth and integration. The devices in railway systems often operate in a narrow and harsh environment with unique requirements. For example, severe air pollution, vibration, shock and EMC are commonly seen.
Low voltage
When bus starts engine from battery, it will draw a lot of current hence to make the voltage low and cause on-board devices not able to operate.
IP camera
It is one of the most important devices and is able to record video 24/7/365. PoE cameras normally need 48VDC power supply with switches that fully comply with the PoE standard to be fed power by Ethernet cable.
NVR
It is a storage device collecting video files and integrated with powerful surveillance software, manager will get notice when any abnormal event happens through it.
