Underground Radio Communication System
What is the Industrial Underground Radio Communication System? The Industrial Underground Radio Communication System (IURCS) is a communication protocol that specifies establishing communication between two points or across one point in large industrial plants. It provides a standard method for avoiding radio interference and equipment failure and efficiently managing plant-wide communications.
The Underground Radio Communication standard is divided into five parts to ensure interoperability; thus, they are often referred to as “Inverter-Based Resources” (IBR).
The five parts are:
Part 1: Radio interface and protocol stack.
Part 2: Command and control center.
Part 3: Space segmentation.
Part 4: VHF Transmission System.
Part 5: UHF Transmission System for large-scale applications.
IURCS is a standard for underground wireless communications created by the IEC. It has been established to avoid interference problems with all other wireless devices in plants (industrial and non-industrial) and other forms of wired communications such as power lines, control systems, etc.
Why Is The Underground Radio System Important?
Radio spectrum is a scarce resource. It is, therefore, necessary to use it efficiently and avoid interference problems with other means of communication.
This standard specifies a method for avoiding radio interference and equipment failure and efficiently managing plant-wide communications.
The radio signals are relatively immune to physical disturbances such as temperature, humidity, or air pressure variations, or ionizing radiation in the atmosphere used by industrial communications systems.
How Does The Underground Radio System Work?
- The system contains a group of base stations (BSTs) and remote terminals (RTs).
- An RT is a small unit with an Omni-directional antenna operating on the VHF or UHF band.
- The BST controls the RTs and provides transmission media access control between RTs and communications channels to support broadcast services, multicast services, access to PSTN, etc.
- The RT provides a receiver and the BST a transmitter for wireless communications
- The system allows the use of two distinct protocols on the radio band: IEC 60909 and IEC 61743, referred to as inverter-based resources (IBR).
- IBR1 protocol is used for real-time voice services.
- The cables connecting the BST with RT are shielded twisted pairs and are typically used as a transmission medium, but they can also be used as a receiver/transmitter cable.
- IBR2 protocol is used for data and non-real-time telemetry services at higher bit rates than real-time telemetry.
- IBR2-based systems also support bi-directional connections to the PSTN.
- The ICS is based on Inverter-Based Resources (IBR). It has been established to avoid interference problems with all other wireless devices in plants (industrial and non-industrial) and other forms of wired communications such as power lines, control systems, etc.
The best Underground Radio System out there
The SMARTCOM 100 LEAKY FEEDER SYSTEM available in Becker Communications is a modern-day version of the time-tested Underground Radio system. The SMARTCOM 100 LEAKY FEEDER SYSTEM is designed for installation in either new or existing underground installations.
The SMARTCOM 100 LEAKY FEEDER SYSTEM connects the RT and the BST with shielded twisted pair cables without the need for grounding. This makes it suitable for many existing applications that directly involve the cable runs between the RT and BST.
