Task 1.10 – Pilots4

• Three phases for 2013-2014

• Phase one October 2013 install 8 end to check for interconnectivity and general operation.

• Leave endcaps to successfully survive Swedish winter

• April 2014 Installed 16 end caps for extended trial to gather data on track and bearing conditions.

• Plan to run for 3 months

• Q4 2014 Extended trial with multiple wagons.

Task 1.10 – Smart Endcap Pre pilots at LKAB5

• October 2013 install 8 end caps for a week.

• Leave endcaps to survive Swedish winter

• April 2014 Installed 16 end caps

• Supported 2 modes of operation – network and stand alone

• Plan to run for 3 months

Wireless system is pink end cap at around 20 seconds

Original Concept7

• Add Condition Monitoring such that we can measure the real operating conditions a bearing is experiencing and wirelessly transmit the results back to the driver and/or train maintenance operations team

• Mount the wireless nodes to each wheel

• The wireless mesh network forms automatically over the journey of the train

Experience!8

• Wireless performance not as good in field as in lab

• Lack of access to trains limits test options

• Time to form mesh is unacceptable (20 WirelessHart nodes = 3 hours!)

• Long thin network (560 nodes) easily become clogged

• Mesh reforms dynamically which is a problem on train

Next Steps9

• Extend 1 year pilot starting Q4 2014 using Malmberget to Lulea line.

• Current system uses WirelessHart;• Link to Arrowhead framework is via OPC-UA and PC software• Possibly move Arrowhead frame work down to node levels

• Current system uses primary batteries.• Move to power harvesting with improved power management (8.5.1)

• Improve methods of coping with wireless links (8.4.1)• Optimise wireless link quality via modelling and validation (8.4.2)
