Project Name: Railway oriented IoT device that is capable to combine sensor gateway functionality with powerful on-board processing and data communication.

Team Size : 5

Tools: C, Simulink, Matab, Python, WebSockets.

Project Description : XPc based system, which collects all sensor data via CAN & published to Master controller using Web sockets. HIL system is developed which could emulate this behavior and to have multiple Sensor controller box, with multiple functionality are connect to master controller. Python library like FLASK Is used as a web server back end & C lib for QNX client-side code is developed to send RESTApi request Stream Sensor data via Websocket from server after successful authentication .Matlab/ Simulink is used for behavior modeling of sensor/ Electro-mechanical components. RTW is used to integrated code to host QNX based system.

Project Name: Elevator controller PCB Testing HIL

Role: Modeling & development

Team Size: 3

Tools: LabView, TestStand, NI PXI-RT

Project description: Objective is to create a HIL Test system with NI PXI hardware to specific check functionality of Elevator controller PCB. IO Interface models were create in LabView and Teststand was used to write functional test cases. PWM and DIO cards were used to inject fault to controller IO lines.

Roles & Responsibilities: Module development to drive IO's. GUI creation for sending parallel bus information. Battery management system modeling.

Project Name: Track Real-time GPS correction system

Role: Platform testing & Application software development

Team Size : 4

Tools C, Simulink, GTK, Matlab, Python, Open MP, Open CV

Project description: This tool is used to identify extended damaged in bogies and Track over time. Sensor data like SPM, ACCEL, GYRO are captured and mapped to GPS portion over real time. The tool maintains a data based on real time and understated the track and bearing condition by performing various analysis like FFT, Waterfall, spectral and this analysis is done over long time to understand long term impacts. This test results are used in warranty related.

Roles & Responsibilities: Generation of synthetic fault data for testing the platform Software in HIL setup. Develop GUI creation for the Selection and conversion tool & helps filtering the data. Develop algorithm to Map all the sensor data points in OSV maps. Design filter for Comfort calculation from acceleration data. optimize GPS data with OSM maps. Model integration and Testing

• Implemented schematics, diagrams for HIL Set up
• Generation of synthetic data for testing the platform Software HIL setup.
• GUI creation for HIL Setup.

Project Name: HIL Test bench for Body Control Module & Instrument Cluster
Role: Application design, Hardware testing, Installation & commissioning

Team Size: 3

Tools: Simulink, HIL, Targetlink, RTW, Labview, C

Project description: The system is composed of a target PC, running under Linux RedHat real-time OS, two fault insertion units, a programmable power supply, an interconnection box (Mapping box) and a load boxes.
