11. ARIZONA PROVING GROUND – NI WSN Project 11 Applying WSN Technology at APG Proving Ground Weather Station Enhancement Project

12. ARIZONA PROVING GROUND – NI WSN Project 12 Proving Ground Weather Station On-Site Weather Station The station records weather conditions for the site to correlate with vehicle testing. Data is archived to network and web.

13. ARIZONA PROVING GROUND – NI WSN Project 13 Proving Ground Weather Station Request for road temps. Current weather station can only read road temperatures for one nearby road surface. Distant/remote surface temperatures are unavailable.

14. ARIZONA PROVING GROUND – NI WSN Project 14 Test Track Temperatures Temperatures are needed for multiple road surfaces: 1)Vehicle Dynamics Area (VDA) 2)Glen Eagles Ride Road 3)High Speed Oval Track 4)2.1 Mile Straight-away

15. ARIZONA PROVING GROUND – NI WSN Project 15 Arizona Proving Ground (APG) Test Tracks Infrastructure Challenge The proving ground has road surfaces spread out over several miles. AC power and cabled network infrastructure are only available in certain locations.

16. ARIZONA PROVING GROUND – NI WSN Project 16 Wireless Sensor Network – Project Concept Use NI Wireless Sensor Network (WSN) hardware to read road temperatures from locations that do not have power or network. Incorporate WSN data into existing Weather Station data collection. Enhance PG Weather Station System to acquire multiple remote track surface temperatures.

17. ARIZONA PROVING GROUND – NI WSN Project 17 Proposed WSN Configuration

18. ARIZONA PROVING GROUND – NI WSN Project 18 WSN Coverage Plan The APG application is targeted to use one 9791 gateway, three (3) 3212 T/C wireless nodes, and one WSN Router node. APG is the proof of concept site. Michigan and Dearborn test sites to follow.

19. ARIZONA PROVING GROUND – NI WSN Project 19 NI WSN network traffic is composed 3 different layers: 802.15.4 >> Zigbee >> NI-WSN. Since NI added a custom WSN layer on top of the Zigbee layer there is more control over the packets going from nodes to gateways and vice versa. The Zigbee network data is never sent directly to the Ethernet network and vice versa. Checks exist that examine data that goes to and from Gateway. Data checks include CRC and bit length confirmation. If packets seem garbled in any way - the packets are discarded. NI WSN Network Security KEY POINT: There is no direct connection between the Zigbee network and the Ethernet on the gateway.
