Introduction● Bangkok Mass Transit System Public Limited

● electric mass transit railway system● 47 Trains

● Objective:● Installation of Vibration Energy Harvester based Wireless Sensor

Networks in 5 Trains

● Estimated Outcome● Reduction in Maintenance time and cost ● Increase Safety

Business Need● Increasing demand of safety in railways

● Reduction in maintenance cost and time of railways parts

● Shift from “Maintenance on Mileage” to “Maintenance on Need”

● Reduction of cost on spare parts (axles and wheels) by 10,000 USD per train per year.

Approach● Sensors

● Vibration and Temperature

● Requires an approx. average power of 3mW that can be produced from 40-50 mg of Vibration

● Communication

● Wireless communications to link the Sensor Nodes with a Data Concentrator and 3G connection to the central server

● Power

● Powered by vibration energy harvester.

● Data Display

● Patterns of vibration and temperature

● Alarm and Notification

Product Description

NO: Normal NW: Normal Worn IR: Inner Race Fault

Assumptions and Constraints

● Maintenance and operation time frame of trains should be adjusted for the

required sensor network installation and testing.

● Approximately, 1 Month monitoring period is required to monitor sensor

readings to calibrate and fine tune the threshold values.

● External factors such as excess noise level can impact the sensor performance and calibration procedure should handle them.
