Subway Monitoring

Wireless Subway Monitoring

Subway MonitoringOverview
For high-performance and reliable transportation network construction, optimization of subway infrastructure and train communication equipment are required. In order to provide safety feeling to passengers, advanced monitoring systems integrate intelligent embedded wireless networking solutions inside carriages and aboard the trains. With current technological developments, higher data rate communication is needed to be transferred within limited time frames, hereafter the WLAN systems with high-performance, reliable and fast connection fulfill main requirements of communication-based train control systems. 
Korenix wireless and wired networking solutions have been integrated inside the train and in each subway station to provide real-time monitoring and control of the carriages. Users are able to collect all the captured video images in the carriages via the 5 rugged M12 ports of the JetNet 2006-M12 switches and using the last port, uplink all the information to the NVR system. Due to their rugged design and the M12 connectors, the switches can easily resist vibration and shock in moving vehicles, and provide reliable data transmission becoming the best solutions for data collection.
Using the built-in Ethernet interface, the JetWave 3220 Wireless Access points later collect the video images from the NVR and through 802.11n Wireless N band connect and communicate the controlled video data to another JetWave 3220 installed in each subway station.
With software changeable antenna design, system integrators can easily choose the omni antenna through the N type socket for extending transmission up to 5km by overlaying multiple radio signals. Subway station administrators can greatly benefit from the 802.11n technology of the Wireless devices, to transfer up to 100M high-bandwidth video and other data from the train within 30 seconds during a short stop of at the train station.

To protect data and privacy, various advanced security features, such as WEP, WPA and WPA2 areused for encoding all wireless transmissions with powerful encryption. The MAC Address filter further provides secure access to the wireless network. For further ensuring high quality of the communication, the JetWave series support spanning tree protocol to avoid loop storm, WMM (QoS) to prioritize classes for different applications, IGMP snooping for multicast stream filtering and NTP for network time synchronization.
In addition to all these advanced functionalities, the wireless APs feature IP65 design and wideoperating temperature to reliably perform under extreme environments.
With all the advanced features, Korenix JetWave 3220 and JetNet 2006-M12 become ideal reliable and cost-effective solutions for ensuring real-time and high-performance wireless surveillance of modern subway systems.
