Design, development & manufacturing of 8051
mcu based D.G. Set Control System for 62.5 KVA Gensets (of Greaves
Ltd. make), installed at ANTARTICA (via the Indian Army), with
the Communications Software on PC, to link up with the system.
This Control System is used to measure all the Alternator Parameters
(3 phase Voltages, Currents, Frequency, Power, Power Factor, etc.),
& Engine Parameters (RPM, Temperatures, Pressures, Flow Rate,
etc.). The above data is transmitted serially to a PC, to be plotted
graphically on screen. Since these units have been installed at
Antarctica, the units were subjected to a rigorous testing procedure
at R&D, Dighi, Pune (a Defense Research Institute), by way
of monitoring the performance in test chambers for temperature
cycles of -30°C to +55°C, & for humidity. |

Design, development & manufacturing of 8051 mcu based,
Computerized Test Bench Data Acquisition System (DAS), for various
types of Gensets (AC/DC, Star/Delta, Low/High Frequency, range
of 0.5 KVA to 125 KVA , etc.), installed at R&D, Dighi, Pune
(a Defense Research Institute), against a Tender Order. The DAS
(Data Logger + inbuilt Digital I/O control), with its own Keyboard/Display
for Online mode of operation is housed in a large Instrument panel,
having sub-racks. Measurements of AC Voltages, Currents, etc.
are done, using the True RMS mode. Commands for various Test Cycles
can be initiated from a Master Computer, in the Remote mode of
operation, to control & select corresponding Sensors situated
in a remote Electrical panel & record all the necessary parameters
to be logged. Commands can also be directly entered on the DAS
terminal. Software is menu driven & user friendly. The results
of the Test Cycles may be downloaded into the Master Computer
for a Graphical Display/Printout for further Analysis/Test Reports.
A remote Slave Computer is also linked to the DAS, where the senior
authorities may observe online any Test Cycle in progress. |

Design, development & manufacturing of Motorola 68HC11
based, Power Line Monitoring & Control (PLMC) System, at the
Osho International Commune, in Pune. There are eight PLMCs installed
at their eight sub-stations, which monitor the power parameters
& serially transmits (on the DIN MSBUS, Fieldbus, isolated
RS485 type) to a server. The client applications consist of Energy
Saving Algorithms, Load Shedding, Graphical Representations, all
developed on the Lab view (of National Instruments) platform. |

Design, development & manufacturing of Philips 89C51RD2
mcu based ASRS Controllers, for Control & Monitoring of Stacking
Retrievers in Material Handling applications within the purview
of Warehouse Automation. These are multi-processor systems to
communicate with an MMI & a PC simultaneously. Communication
distances are large, & the protocol used is RS485 isolated.
The Controllers have to run in a very electrically noisy environment;
hence a lot of safety interlocks have been built-in for the hardware
& for the software. Front-end software, on PC, is a VB application
for Inventory Control, with facility to interface with SAP/ERP
etc. |

Design, development & manufacturing of PIC 16F628 mcu
based Infra-Red Curtain Protection Systems. The Transmitter
& Receiver circuits work on Modulation & De-modulation
techniques using 38Khz Carrier Frequency. |

Design, development & manufacturing of Embedded Design
System Tools, like Flash Mcu Programmer & Development Board.
The development board is useful for 8051 & PIC practice sessions.
The front-end software, on the PC, has been designed using VB,
with the mcu device database in Access. |
