COMPANY PROFILE

BHARAT ELECTRONICS LIMITEDINTRODUCTION

Bharat Electronics Limited (BEL) was established in 1954 as a Public Sector Enterprise under the administrative control of Ministry of Defense as the fountainhead to manufacture and supply electronics components and equipment. BEL, with a noteworthy history of pioneering achievements, has met the requirement of state-of-art professional electronic equipment for Defense, broadcasting, civil Defense and telecommunications as well as the component requirement of entertainment and medical X-ray industry. Over the years, BEL has grown to a multi-product, multi-unit, and technology driven company with track record of a profit earning PSU. The company has a unique position in India of having dealt with all the generations of electronic component and equipment. Having started with a HF receiver in collaboration with T-CSF of France, the company's equipment designs have had a long voyage through the hybrid, solid state discrete component to the state of art integrated circuit technology.

BEL was among the first Indian companies to manufacture computer parts and peripherals under arrangement with International Computers India Limited (ICIL) in 1970s.

Market / Customer details of CMS

Indian Navy Order received for CMS 17 , ATM switches and NMS Order received for CMS reference system LOI received for CMS - SNF including ATM switches , NIUS and NHMS

Scope of CMS

Development of nodes for CMS 17 and CMS SNF Supply of ATM Switches, NMS. NHMS, NIUS and simulators for BEL equipments fitted on board INS - RANVIR by BEL, Bangalore System software development jointly BEL GAD and CRL Delhi Complete integration responsibility with AISDN for CMS 17 and ships sensors and weapons for CMS SNF with BEL GAD.

Functions of CMS

Acquires data from ships sensors Integrates different type of platforms Process, store, integrate , correlate and display the tactical data in real time Gather data from other aircrafts operating in the fleet through data link to collate, process, integrate and to present a comprehensive tactical picture of the area of operation Identification, classification threat assessment of targets and automatically advise the command on the engagements Advise the command on course of action when invoked activated by events occurring in the equipment with which the CMS is integrated Decision support system for command Provides target designation to the interface fire control system for sub surface , surface and air targets Monitors the execution of weapon firing , communication and status after firing Off line map preparation facility for loading of charts

Computer Complex (CC)

Central Computer Processing of track and other data Central database Dual Redundant configuration (fault tolerant) Provides digital interface to external sensors and weapons on ship through NIUS Validates incoming data Central Database of weapons connected Dual redundant configuration (fault tolerant) Provides a high resolution graphics and radar video presentation Consists of two high resolution display screens for Graphical and TOTE Presentation Provides Man Machine Interface for operator input through keyboard, tracker ball and Touch Input Device (TID)

External System Interface (ESI)

Dual Multifunction Console (DMFC

Multi Function Horizontal Console (MFHC)

Provides a high resolution graphics and radar video presentation on a large horizontal screen Provides multiple operators (three) with common display picture for taking joint strategic decisions and chalking out action plans Additional 15 display is provided for each of the operators to display the primary and secondary display picture Independent MMI for all three operators

ATM Switch

Provides backbone for data communication Most nodes of CMS on StM I Interface(155 Mbps) EI Interface (4 Mbps) only on RDDU and SCP in CMS 17 Based on technology on CDOT through BEL Bg Dual Redundant Configuration

Network Interface Unit (NIU)

Facilitate the data exchange among various equipments on board ship in required format Converts data received from the connected sources system to STM I stream for sending it over the ATM Switch and vice versa Provides a central place for health monitoring and diagnosis of the CMS segments. Generates and updates tactical scenarios based on operator inputs Used as a training , testing and maintenance tool

System Control Panel (SCP)

Simulator

Radar Data Distribution Unit (RDDU)

Provides raw radar data to the DMFCs and MFHCs Provides the control of various radar parameters such as pulse width , PRF , antenna RPM etc. to DMFC Operator

Video Extractor and Tracker (VEXT)

Receive radar data of the RAWL 02 MK2 Performs, plots extraction and auto initiation of air targets Tracking of targets

Test plan for MMIC

MMIC is a part of DMFC used in Combat Management System. MMIC which stands for man machine interface card is an important tool for establishing effective communication between different parts of the system on - board ship and also various controls. To develop a test software for the testing of the MMIC card of the CMS 17 using assembly language programming of 87C51 microcontroller and C programming.

Basic Aim of The Project

Approach to test the MMIC

Using Assembly Language Programming Test program for effective chip select for suitable LED indication To establish communication between ADC and PPI for obtaining bearing and gain To test the serial port communication

Using C Programming

To send the data to serial port COMPORT for effective LED indication and check for loop back the data using serial port. Also create features for further additions in future.
