Wireless Mesh Network
for Subway Station & Tunnel Applications
Safety • Security • Efficiency
How it Works
Controlling and monitoring subway platform and tunnel lighting fixtures, and battery backup systems through clearNET comprises 3 interrelated components:
1. NODES
Nodes control light levels and monitor driver status and battery health. Each node includes a wireless chipset to transmit and receive network data between nodes and gateways, firmware and protocol optimized for communication in transit/tunnel applications; and a special antenna designed for signal propagation in non-cooperative environments.
2. GATEWAY
The nodes communicate with the gateway via a mesh network. The gateway includes a chipset, processor, and memory to store the accumulated data sent by the nodes. The gateway can be configured to connect to the clearNET cloud platform through a WIFI or hardwired connection.
3. END USER DEVICES
End user devices (desktops, laptops, tablets, mobile phones) interrogate the gateway either directly or through the cloud and compile the data in a web-based graphical user interface (GUI) for analysis. End users can monitor lighting equipment status, or send instructions to the gateway to modify the output level of the lighting fixtures based on real-time requirements.
clearNET IS PROGRAMMABLE TO MONITOR AND CONTROL TO MEET THE LIGHTING REQUIREMENTS OF EACH SUBWAY STATION LOCATION
ClearNET is a communication channel to monitor and control transit system assets & environments, allowing the controller to:
Provide a modular and expandable power and data communication infrastructure for non-lighting mechatronic system sensors and actuators – temperature, smoke, hazardous materials.
Control the level of illumination specific to each activity within the subway station – passenger safety and energy efficiency.
Monitor health of lighting systems for effective and efficient maintenance and asset management.
International Transportation Systems Utilize IOT
Major transportation systems utilize IOT to monitor and control the performance of their logistical, safety, energy and maintenance functions with effectiveness and efficiency never-before imagined. clearNET facilitates IOT benefits within subway station environments. Focused on facility infrastructure maintenance and asset management, clearNET dramatically reduces associated operational costs.
Established Experience: Incorporating Iot Into Subway Station Design:
IOT is widely accepted as a means of achieving the primary mission of all mass transit systems – to transport people safely and comfortably without bankrupting the economy or destroying the ecosystem. Although select architectural firms, engineering firms, contractors and manufacturers have established reputations in most transportation applications, communication through a tunnel environment continues to be the weak link.
The SNCF French
National Railway
The SNCF French National Railway transports over two billion passengers annually. The SNCF is reducing maintenance costs, down-time, safety hazards and improving the reliability of it tracks, trains and signals through its recent adoption of IOT. Tens of thousands of sensors are collecting and transmitting data that is empowering the maintenance system with proactive strategies that improve reliability, safety and security.
The London
Underground
The London Underground, one of the world’s oldest public transportation systems, uses a central control center to monitor and aggregate sensor data collected via network-enable sensors from across the tube system. The ability to monitor equipment performance and automate maintenance functions improves customer satisfaction and decreases costs.
NYCT:
The New York City MTA
The New York City MTA is utilizing clearNET to increase the reliability and reduce the maintenance costs of its subway tunnel emergency lighting systems. The tunnel lighting fixtures will be outfitted with nodes that will monitor the health of the lighting elements, power drivers and emergency power back-up system.
