Overall Strengths

The aim of the product is to control a Diode Laser System used for Skin operations.  The system is bifurcated into 4 modules as Digital I/O, Analog I/O, Communication software, Trigger pulse generation software. The I/O Controller is intended to read/ write the Control Instruments. I/O System consists of ADDA ports. The Device Driver drives the ADDA I/O Ports, so that Windows CE does not throw any exception for accessing the Hardware from a User-Mode Application. DIO & ADDA data is retrieved from IO ports. Temperature sensor, Energy sensors, High voltage power supply and other digital signals can be analyzed on system operation. The communication software is developed to communicate between the ARM & AVR processor. The Trigger pulse generation is handled in AVR processor. The signals generated are Single, 1, 2, 3, 6,10Hz of 4ms, 7ms, 10ms, 450us.

The actual goal is to develop PCI Kernel mode drivers for PLX PCI 9030 and to make PCI based DIO, ADDA Control interface board through ADSP 2185. The hardware is PCI Compatible & uses PLX PCI 9030. The Target is ADSP 2185 for this DSP-PCI board. PCI 9030 acts as a bridge between Pentium & ADSP 2185 processor. A driver is designed to support PLX PCI 9030 type and any number of same boards in the target. The drivers support all boards functions via the PCI bus including interrupts, Memory Mapped and programmed I/O. A DPRAM CY7C09349 from Cypress is used for memory handling. Both Processors can access this DPRAM at the same time.
Peripheral Component Interface (PCI) PCI is an intelligent, High - performance interface that enables system developers to integrate a variety of functions. It’s a 32 - Bit controller operates at 33MHz clock PCI v.2.2-compliant device with burst transfers up to 132Mbytes/sec, the PCI 9030 delivers high performance to new PCI-based adapters and those migrating from legacy designs. The device's 60MHz local bus, 3V/5V operation, and programmable general-purpose I/Os (GPIOs) and chip selects bring unprecedented flexibility to a wide variety of memory and I/O devices. The combination of these features make adapters used in high-bandwidth applications. It is designed to interface with memory-mapped devices.

The aim of the up gradation is to cope up with the real time & to make more reliable system.  The system is bifurcated into 3 modules as GUI, I/O Control Software, and Communication software. The I/O Controller is intended to read/ write the Control Instruments. This is connected to the Control system board through an ADSP Subsystem. The Control Software is maintained in ADSP 2185 processor & on windows. These two processors communicate through RS232. A safety system is designed in such a way that both processors communicate continuously to prove their existence. The entire user level process is controlled & maintained in windows. Depending on the User inputs the data has been processed & sent to ADSP for controlling the Control instruments.

This project aims at providing an IT solution for R & D Inventory system.. This is developed using Client/server Technology. This has various modules like Inventory, Sales,& HRD Information System. The main aim of the project is to automate the R &D  totally in aspects like tracking of Goods In/Out, Inventory, Sales . The Inventory module maintains the stock of different fields related to the maintenance of the R & D.  It maintains the details about each category, product, and suppliers of each product and prepares the orders based on the reorder level of a product. It looks about the daily transactions of all the sales. Reports will be generated for every aspect of the requirements.

This project aims at providing a simulated environment for a person to learn driving a heavy vehicle (e.g. A truck). The CGI is being developed using C, Win32 API, Open GL where as the IS is being developed using C++ (VC++ 6.0). A driver has got controls like steering, gear handle, brake, accelerator, clutch etc. to control the movement of the vehicle and an I/O system transforms the parameters like steering handle, speed etc to the CGI software.  The CGI Software uses the OpenGL calls to render the 3D world on a display unit placed in front of the driver.  This makes the driver feel as if he is driving in the real world. The CGI and the IS modules interact with each other using sockets.
An Instructor Station monitors the events and generates the performance reports in addition to controlling the driving stations. It can send some dynamic objects and scene files at the stating of the session to any driving station.  A sound module caters to the needs of generating vehicle sound depending on the speed, gear and also the horn sound whenever the driver operates the horn.

The objective of the Simulator is to provide training to the employees of NPCIL on Nuclear Power Plant Control Operations. The Instructor Station has a user interface for the Plant Instructor to execute certain commands, which are intended for Plant Operation. The Instructor Station acts as a Host for Six I/O Controllers, MMI System, and Digital Recording System.
The commands from ISA will be sent to Run Time Monitor (MTR), which monitors all the communication activities between Host and other systems, Simulation model activities and synchronizing them in Real Time mode of operation with ISE Clock, through Shared Memory.
The commands are: Debug Simulator, Run, Freeze, Display Description of parameters, Display Variables, Add Variable for Display, Set Frequency for Model, Insert Model, Model On/Off, Taking Snap Shots, Connect to other systems, Make Panel available/not available, Set Malfunctions, Set the Simulator Frequency, Loading earlier snap shots in to system, Generating Safe State Values, Loading Safe states, like that to name a few.  Each command executed and error messages are continually displayed in a Message Window and will be logged into a log-file for performance evaluation of the Trainee.

The I/O Controllers act as Server and the Host/Instructor Station request for Control Panel input parameters and I/O Controller processes the Request, reads the Panel Instruments, and sends the same to the Host. Host will send data to update Control Panel Output Instruments to I/O Controller. I/O Controller updates the Panel Instruments. The data read by host will be written into R/W memory segment, Simulation Models will use the same, and the Models in turn will write output parameters into the segment. The Comm. Module reads this segment and sends the Output Parameters to the I/O System.
Each I/O Controller creates Server Socket and waits for connection request from Host. Host creates an individual socket to connect to each I/O Controller. When Instructor Station gives a command, Connect to Panel, these sockets will be connected to each I/O Controller respectively. Then MTR will control the transmission and reception to/from the I/O Controllers and accessing of the R/W Memory Segments by the Comm. Modules.

The I/O Controller is intended to read/ write the Control Panel Instruments. This is connected to the Panel through an I/O Subsystem interfaced on ISA Bus. I/O System consists of Digital input/output and Analog Input / Output cards sit on an I/O Bus. The I/O Bus Interface card connects ISA BUS through an ISA BUS Interface card sits in ISA Bus. The Device Driver enables the process to access the I/O Ports, so that Windows NT does not throw any exception for accessing the Hardware from a USER-MODE Application.
I/O Software provided with user interface, enables the user to configure the I/O, scans the I/O and has facilities to diagnose the I/O System. The configuration of the I/O System will be saved on to disk for further use.  When the I/O System is powered on, it loads the configuration from disk, performs diagnostic tests, and Compares the present configuration with the old configuration. If no errors are found, it directly switches to the On-line mode where it keeps listening to Host. If errors are found then displays them in a List Box and forces the User to go Off-line, where he has to respond the errors to diagnose them. In Off-line user can perform various commands like Scan I/O configuration, diagnostic tests, Read/Write various I/O's.
