DWSD PC-713: Design/Build Instrumentation and Control System Replacement - Detroit, Michigan
A significant portion of the PC-713 project was to provide DWSD’s System Control Center operators access to live data readings from their entire transmission and collection systems. In addition to 37 pumping facilities, over 200 remote sites were added along major water and sewer pipelines. Making this data available at the SCC required tying into DWSD’s existing radio network, and in some cases expanding the backbone.
A separate
headend was
created in
order to make
the data
available on
the Ovation
system and this required the development of custom software that combined the Ovation architecture with the Utilinet data drivers for efficient use of the radios. Custom communication drivers also had to be created at the pumping stations and remote sites in order to recreate DWSD’s Modified DF1 message format.
All of the radios had to be programmed using DWSD’s standard naming conventions as a guide. Actual GPS coordinates were used for the radio locations and configuration settings were adjusted to provide the optimal links into the mesh network. During the testing of the sites,
adjustments were made to the physical installation (antenna heights, cable types…) to increase the connection strengths of the radios.
