Application of Network Management

• We are managing a Network of Indian Railways (
  Microwave Repeater Station ) which is a main
  source of Communication media for Indian
  Railways.
• What We have a Number of Divisions in the
  Regional Railways e.g.. Western Railways, and
  these Divisions are having divisional HQ.

• These divisional Head Quarters are looking after
  the administration of Railways Traffic in the
  division. All divisions are almost having Railway
  Track of almost 200 to 250 kms. Consisting 5 to 7
  Repeaters of Microwave Network in the division.
• The mainpurpose of These repeater is to boost the
  signal and continue the communication link for
  smooth working in the division.

• Every Repeater Station is isolated by almost 55
  to 60 kms. Distance ,this depends upon the
  terrain of the region.
• There are many equipment housed at these stations
  in order to make communication workable, like
  Transmitters (2 nos.) , Receivers( 02), 24 V
  Power Supply , stand by supply (secondary) using
  Battery Bank, Stand by Battery Bank, D/ Generator
  set, Battery Charger, Float, SPV Supply , Air
  conditioner Set etc.

• These Transmitters and Receivers are having many
  important Analog and Digital signals. These
  Signals are presently monitored Manually , i.e..
  24 hrs . Man Power is provided at all these
  locations. But efficiency and duty attendance is
  poor. In order to get better efficiency we have
  devised a system called NMS for MW .
• Almost 100 Analog and 56 Digital Important
  Signals are required to be monitored and some to
  the extent of 16 Digital Out Signals for
  controlling devices like
• Switching of Transmitter,
• Switching of Receivers,
• Switching of Battery Bank from Load to Charger
  and Charger to Load in secured way .
• Switching On/ off Diesel Generator Set
• Switching On/ Off SPV supply .
• Monitoring of Room Temp Switching Air
  conditioner.
• And On top of this all Remotely sitting at the
  Divisional Railways HQ.

• One can do it using system developed by us.
• We have Developed following components
• Data Loggers stationed at all the stations for
  Data acquisition of the signals of local
  station.Compatible to requirement of nos. of
  Analog and Digital Signals.
• These Data Loggers are connected to each other in
  daisy chaining /Multi drop Network topology and
  finally to FEP Front End Processor and then To
  FAS Front Analyzer System through Memory Buffer.
  Application software and Truth / Lookup tables
  are residing in FIFO memory Buffer.

• Connectivity of Network
• All the Data Loggers are connected to Radio link
  of Microwave through Modem which is addressable.
• FEP is connected to Memory Buffer and keep
  acquiring data from Buffer.
• Memory Buffer is in continuos poling mode and
  keep acquiring data from all the data loggers .
• FAS is connected to FEP and can remotely access
  and control the activity of the system.
