Linux based Power monitoring system Sep 2014 – Feb 2015
Team Member
This 'Embedded Development Project' was designed for detecting fault (DFR) and measuring Power Quality (PQ) of the High Power electrical distribution system. The system has a CPU card and eight other daughter cards which are interfaced together to form a single system. The major components of the system include:
• FPGA, DSP interfaced to the CPU. The CPU programs the devices during power on. • The device stored the electrical data collected in Compact flash. • The device supports real time streaming of data over Ethernet. • The device provides on-demand transmission of stored data over Ethernet. • Remote upgrade of CPU and peripheral firmware through web server. • Configuration and control of the system through web server. The project included hardware design and ‘Board bring up’ (with Linux kernel customization, cre-ation of a stable RFS) to complete device driver and application development.

Team : 8 members Role : Team member
Responsibility:
Driver and kernel layer:
• Design and development of FRAM, Battery and Temperature sensor drivers over I2C. • Developed I2C driver to interface EEPROM and RTC.
Application:
• Designed the dispatch process optimized for real time performance. • Designed and developed the System Monitor process which monitors all other processes and refreshes
the watchdog. • Design and development of firmware upgrade and password protection. • Design and development of file access library and data retrieval process. • Developed prototype to communicate devices through different network by using different gateway. • Developed an application which has provided an interface to front end application to download CDI file
from device. • Design and development of drivers for external peripherals accessing using I2C. • Developed the System Monitor process which monitors all other processes and monitor the
temperature of device and shutdown the device when it exceeds the specified limit. • Developed an application which indicate the available battery in percentage and glow the LEDs of UPS
card.
• Regular interaction with customer for improvement of design specification. • Unit, Integration & System testing.
Standard Man Machine Interface July 2012 – Nov 2012
Team Member
MMI communicates with CPU to obtain the status and other information. The Overview screen on the LCD re-flects the status of the device. Using the left or right arrow key, the user can view detailed information of the device.
Responsibility:
• Design and developed an application for Man Machine Interface (MMI) process to display latest
thousand logs on MMI. • Introduced reset functionality for the device through Man Machine Interface. • Designed MMI screens by using easyGUI tool, to display unicode character. • Unit, Integration & System testing.
