RAILIABLE: RAILWAY CONDITION MONITORING SYSTEM Students: Aisha Alkuwari, Muneera Abdulla, Nouf Al-Khalifa, Maha Al-Naimi | Mentor: Dr. Shehab Ahmed | Assistant: Randa Al-Qudah, Mohammed Adel II. Literature Survey I. Introduction • Use of In-service cars, Ultrasonic waves to detect track defects after they occur • Design Automated Condition Monitoring equipment for railway tracks • Parameters: Temperature and Stress Problem: Abnormal changes of parameters: Temperature and Stress The Design: • Detects abnormal changes before significant failure can develop • Abnormal changes in temperatures and stress causes railway tracks to crack and/or buckle • Types of stresses experienced by the track: Bending Stress, Thermal Stress, and Residual Stress Benchmarking: Sen. Track™ Track Monitoring System MRX Rail Surface Crack Measurement System (RSCM) Rail. Stress Monitor™ Railiable Detection detects crack and defects detects abnormal track geometry changes sensing stress and temperature Measures stress, temperature Way of detection automatically manually automatically Data transmission wireless - wireless Data storage capacity 30 days of data capable of covering several kilometers in a day 6 Months of 10 Minute Intervals continuous monitoring system Image • Helps to increase reliability and safety of railway tracks Benefits III. System Modeling 1. 2. broadcasts customized warnings over a local radio channel or by wireless modem complete detection package for monitoring the most prevalent hazardous railway conditions 1. 2. 3. small and light produce an accurate report for long stretches of track Information is displayed and recorded in a supplied rugged tablet for immediate use or as part of a maintenance record 1. self-Contained (No External Wiring) 2. simple installation 3. up To 10 -Year Battery Life 4. monitors Rail Temperature and Stress 1. 2. 3. able to detect changes of parameters before the defects occur continuously monitors the parameters withstands high temperature V. Simulations DAQ NI 9237 Arduino board 1 -Sheeld board Temperature sensor Strain gauge NI 9945 Metal specimen Strain gauge setup Temperature sensor setup Lab. VIEW code for strain measurements VI. Experimental Results IV. Functional Modeling Strain Gauge waveform output VII. Conclusion Strain output VIII. Future Improvements Temperature data logging • It is important to monitor the conditions of the railway tracks to avoid track defects • Building the railway track monitoring system in Doha is critical because of the hot weather • Use the system in real applications • View the stress values in the i.
