Mid Coast Water – High Speed Data

Mid Coast Water High Speed DataMid Coast Water is responsible for Sewerage assets covering the areas of Taree, Forster, Tuncurry, Stroud, Hawks Nest, Tea Gardens, Nabiac and Buledelah on the NSW Mid North Coast. Mid Coast Water has around 300 Radtel telemetry units ranging from 5000 Series units that have been operating for nearly twenty years through to the latest 8000 Series units and Omron PLC’s.

Objective

The objective of the Mid Coast Water High Speed Data project was to increase the speed of the network from a 1200 baud network to a more efficient, high speed packet-switched data network. This project is seen as necessary to allow for increased data collection requirements at current RTU’s (up significantly since the communication backbone was first commissioned in the 1980′s) and future expansion of the network.

Equipment Used

Mid Coast Water High Speed Data

  • Rack Mounted TAIT TB7100 Repeaters with IMARK 5020RM Power Supplies and Battery back-up.
  • 8000 Series CPU Upgrades
  • TAIT TM8000 Radio’s with High Speed Data option

Methodology

  1. The repeater network was first upgraded to allow for higher speed radios. After careful consideration it was decided that maintaining an analog network would be the best solution as it would allow a gradual upgrade of sites without having to replace hundreds of RTU’s at once. Tait TB7100 equipment was chosen for the communications backbone which supports the older T500 Radio’s along with T2000′s and the latest TB8000 Radios.
  2. Upgrading of FEP (Front End Processor) or Master RTU equipment at the Server locations meant adding high speed TAIT 8000 Radio’s that would be capable of communicating at 19.2k baud.
  3. Gradual upgrading of the field RTU locations means that selected RTU’s are capable of communicating at 19.2k thus reducing the channel loading across the network.
  4. Further speed advantages are implemented by utilizing Radtel RDCMP protocol compression which uses compression technology to reduce the size of bulk transmission such as File Transfer and bulk Change of State Transfer.

Result

Now that this first stage of network upgrading has been completed successfully and the selected test sites are operating comfortably at high speed, Mid Coast Water has decided to continue the rollout of this network across the rest of the network for maximum network efficiency and future expansion.
