Scalability And Universality Of The Onboard Condition Monitoring System
Dec 19, 2017

    Both Rolling stock and track related information shall be monitored and transmitted from the same sensor node. The data communications system shall be scalable to allow addition of sensor nodes in future. Data concentrator shall be modular and should be scalable to accept connection of additional sensors. For the protocol to be used for communications of the Data concentrator, kindly refer to clause 5.5.4. Apart from the hardware connectivity, software handshaking with sensors must also be ensured.

Additional input device in wireless fashion to the data concentrator to add more sensors. The system shall be applicable to both passenger and freight trains/operationsSystem shall be capable of being scaled-up in future, with simple addition of sensors by connecting them to data concentrator, to monitor the following parameters. The list of parameters is not exhaustive and is not limited to only the ones mentioned in Annexure – 

1. Additional parameters to be monitored in Passenger Coach:

 a) Water level monitoring in water tanks on board the coach. Monitoring of internal temperature of carriage shall be available.

 b) Air-spring pressure (where ever pneumatic suspension springs are fitted).

 c) Wheel slip and slide control system.

 d) Air brake system piston travel and Brake cylinder pressure.

e) Brake pipe and feed pipe pressure.

 f) Distributor Valve performance of the Air Brake system.

 g) Automatic door closer system.

 h) Additional wheel damage differentiation such as flange wear, out of round, etc.

 i) In case of Diesel Engine driven Diesel Multiple Units (DMUs), the health of Gearbox, traction motors and compressor(s).

 2. Additional parameters to be monitored in Freight Car (Wagon):

 a) Brake system’s brake piston travel.

 b) Brake cylinder pressure.

 c) Brake pipe and feed pipe pressure.

 d) Brake system Distributor Valve health – functional or non-functional.

 e) State of wagon – whether Empty or Loaded.

 f) Additional wheel damage differentiation such as flange wear, out of round, etc.

 g) Broken spring in the suspension system.

 h) Crack on bogie frame.
