The following are the projects undertaken:
Control system for Multi-axis Sewing Machine with HMI interface
The HMI design and development for Control system for Multi-axis Sewing Machine with HMI interface
includes the design and development of 6-axis stepper motor control system with 60 Inputs/Outputs sequential
controller. It has a HMI with touch screen, for display and selection of sewing patterns.
Control System (SCADA) for Fuel Filling Station
The SCADA is about filling fuel in tankers automatically and precisely.
It included system communication facility enabling and monitoring the fuel
filling station through a computer.
Attendance recording and Access control System using optical / magnetic / barcode
Recording presence of a person – viz. swipe cards (optical, magnetic, barcode), biometric sensors (fingerprint),
RF cards etc. The micro-controller based product included standard recording features and additional features like
Brake Testing System
It is an automobile end of line test equipment and used for Brake Testing and to calculate brake efficiency.
Fire Alarm Monitoring System with graphical layout on PC
GUI software designed to communicate with client’s Fire Alarm Monitoring System. The software allows users to draw map
of the premises where the system is installed. Upon detection of Fire, the software provides audio-visual indication
of this condition and also displays shortest-path from Fire station to the affected area. It includes several other
features like maintaining a log of events.
Automatic Identification System (AIS)
It is marine communication equipment. It uses GPS and sensors for identifying own position and inform it
to other ships over radio communication link. The radio link uses Time Division Multiple Access (TDMA) principle.
The product was designed to meet standards of IEC, ISO, and NMEA.
Molten Metal Temperature Measurement Instrument
It is a hand-held battery-operated instrument with auto-shut-off feature. The digital electronics was re-designed
to replace old design which had obsolete components. Consequently firmware was also completely re-engineered and new
features were added to it.
Ecomate – Hand held interface for drives
It is a hand-held HMI designed to interface with an A.C. Servo drive (Indramat). It was
designed and Developedd to work in shop floor environment. It was been provided a display and keyboard
for user interface, through which user can monitor and change various parameters of the drive.
Firmware for Electronic Gauge
Firmware of their existing gauge was completely re-engineered and a new
RS485 communication protocol was implemented for communication
Industrial grade HMI with digital and analog I/O interface and graphics LCD interface
The project displayed various parameters of the process on the Graphics LCD in different fonts. Calculations on the
input data were done and the processed data was shown on the LCD. The graphical display unit was configurable and as
MCGAM700 (Multi Channel Area Gamma Monitor)
Multi Channel Area Gamma is a 4 channel Area Gamma monitor designed for measuring the ambient gamma radiation
levels in various areas in a radio chemical plant. It displays radiation level and generates audio / visual alarms
when radiation levels exceeds set limit in any of the detector channels.
HFM (Hand and foot monitoring system)
HFM unit is a single board computer controlled unit with touch screen interface. It is Developedd for
measuring the counts of alpha, beta and gamma rays in human body, indicating count rate i.e. normal
