COMPANY PROFILE
BHARAT ELECTRONICS LIMITED
INTRODUCTION
 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.
 Location of BEL Units in INDIA

 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 ship’s sensors and weapons for CMS – SNF with BEL – GAD.
 Functions of CMS
 Acquires data from ship’s 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 page 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

External System Interface (ESI)
 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)
Dual Multifunction Console (DMFC
 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)
 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
System Control Panel (SCP)
 Provides a central place for health monitoring and diagnosis of the CMS segments.
Simulator
 Generates and updates tactical scenarios based on operator inputs
 Used as a training , testing and maintenance tool
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.
Basic Aim of The Project
 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.
 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.
