1 IOT & RAILWAY ROLLING STOCK ENABLING MONITORING OF OLDER FLEETS SNCF ROLLING STOCK ENGINEERING DEPT. DIFFUSION LIMITÉE MARCH 20TH, 2017

2 VISION : NEW MAINTENANCE ORGANISATION SMART TRAIN 1 Better knowledge of operating condition CLOUD 2 Improvement of data quality CORPORATE IT 3 Lifecycle management optimisation WORK ORDERS ANALYTIcs 4 Data-driven process 2 MARCH 20TH, 2017 ASSET MANAGEMENT SYSTEM

3 GETTING DATA FROM LEGACY FLEETS Sensors Fully integrated to the Capteurs intégrés au train control (or matériel roulant maintenance) system Sensors not interfering with train systems, except power supply Sensors not interfering with train systems Connectivity Wired to an on-board train network Wireless to an on-board communication gateway Direct network connectivity with LPWA Cost of the 1 st data stream Very high except new train or heavy overhaul Moderate: power feed and gateway integration Lowest cost for single sensor use case 3 MARCH 20TH, 2017

4 CONNECTING OLDER FLEETS : 4 MAIN CATEGORIES 1 Tank level monitoring 2 Remote log retrieval Fuel, sand, water, oil Connect maintenance plugs of control units Operations management Enable anticipation Cost reduction Reliability Availability 3 Operating hours count Telematics on significant devices Cost reduction Better maintenance planning 4 Health monitoring of critical systems Monitoring critical thresholds: temperature, vibration level, peak current Reliability Cost reduction (avoid heavy repair) DIFFUSION LIMITÉE MARCH 20TH, 2017

5 USE CASE : WATER LEVEL MONITORING ISSUES Toilets availability & Delayed trains Replenishment management 5 MARCH 20TH, 2017

6 IMPLEMENTATION : 4 TRAINSETS 9 MONTHS Pressure sensor on the bottom of the tank Transmission: off-the-shelf LPWA modules 6 MARCH 20TH, 2017

7 DATA TRANSMISSION LESSONS LEARNED IN-MOTION TRANSMISSION SIGFOX : Tests have shown that there is no in-motion (> 30km/h) data transmission Better with LORA, capability up to 100 km/h, depending on network STATIC TRANSMISSION 6273 of 6440 messages correctly received (97,40% success) position R1 R2 R3 R5 R6 R7 R8 Signal (dbm) - 118,4-117,4-118,4-116,7-117,3-115,5-116,5 Bad ( below -136 dbm) <1% Good (-135 to -123 dbm) 32% Excellent ( -122 dbm): 67% DAVID BIEHLER INGÉNIERIE DU MATÉRIEL POLE DE BISCHHEIM (BSE) 7 MARCH 20TH, 2017

8 TANK LEVEL MONITORING RESULTS (1) WATER LEVEL PER CARBODY trainset #720 R1 R2 R3 R5 R6 R7 R8 Mean level 84% 80% 79% 81% 84% 76% 70% Minimum level 47% 15% 13% 34% 35% 25% 0%* Conclusions (1) Overall mean level of water tank is 80 %. This could allow to suppress unnecessary replenishments. Low level still exists, can be and were flagged thanks to monitoring, before assigning the TGV on a commercial journey.

9 TANK LEVEL MONITORING RESULTS (2) WATER LEVEL OVER TIME Water consumption vary significantly depending on toilet s location. This was expected. Water replenishment vary significantly depending on toilet s location. This was less expected! Conclusions (2) Replenishments being charged, but not full-filled! contract management DAVID BIEHLER INGÉNIERIE DU MATÉRIEL POLE DE BISCHHEIM (BSE) 9 MARCH 20TH, 2017

10 CLIENT S BENEFITS BETTER EFFICIENCY THROUGH BETTER KNOWLEDGE FIELD DATA MAY IMPROVE TRAIN DESIGN Mean water consumption / hour for each toilet position Systematic water loss after replenishment (5% - 11%) (tank design) SUCCESSFUL EXPERIMENT! - Monitoring currently being implemented on 30 TGVs (Paris-Lyon) - Extension to all TGVs with clear water toilets in preparation 10 MARCH 20TH, 2017

11 IS EVERYTHING THAT EASY? LIMITS OF CONSUMER ELECTRONICS On-board railway systems meet specific needs Passenger s safety (fire & smoke regulations) Reliability and maintenance cost through compliance with standards for EMI, vibration, maintainability Strategy : going for a railway-ready communication node & gateway 11 MARCH 20TH, 2017

12 AS A CONCLUSION: IT S A BEGINNING! Real opportunities with IOT Pushing forward with more data Moving the organisation 12 MARCH 20TH, 2017
