DMR System & Integration

DMR System & Integration with existing PMRTS Network

Overview

IndianOil leverages high-calibre people and state-of-the-art technologies to tap all forms of energy most responsibly and delivering them to the consumers most affordably. one of the largest customer interface in India, IndianOil reaches precious petroleum fuels to every nook and corner of the country through its network of over 56,000 plus customer touch-points, surmounting the challenges of tough terrain, climate and accessibility.

The purpose of the system is to provide Digital VHF Communication in the Plant area. It is a big plant and there are large number of Analog Radios and customer would like to keep on using them till they have useful life

Features of the Installed System

  • Motorola’s MotoTrbo Radios used along with third party hardware. Main products were as follows:
  • Interface of existing analog system with Digital VHF DMR System thereby helping refinery use the existing analog radios till their useful life and reducing expenditure.

Communication Between PMRTS (Analog) & DMR Setups

The purpose of the system is to provide Digital VHF Communication in the Plant area. It is a big plant and there are large number of Analog Radios and customer would like to keep on using them till they have useful life. Communication is established between existing Analog Radios and proposed Digital Radios.

INT-1 is interface system provided by us that establishes communication between Analog & Digital Radios. We have provided sixteen such interface systems (one for each existing channel.)

RS-1 is Repeater Setup. Five Repeaters are installed in Plant.

Communication flow is as follows:

  • Between Analog Radios (AP-1 to AP2): It goes on as previously through existing PMRTS setup.
  • Between Digital Radios (DP-1 to DP2): Digital Radios use available free channel through Digital Repeater system in Plant. Channels are allocated using Motorola’s Capacity Plus system.
  • From Analog to Digital Radio (AP-3 to DP3): Call lands on Analog Base in Interface Setup, converted to Digital and transmitted by Digital Base Station to Recipient Digital Radio through Digital Repeater
  • From Digital to Analog Radio (DP-3 to AP3): Call lands on Digital Base in Interface Setup through Digital Repeater, converted to Analog and transmitted by Analog Base Station to Recipient Analog Radio through PMRTS setup.
