It's the middle of summer season is in full swing. A corporate campus in the suburbs of Portland, OR with a central control scheme lost a telephone connection. This phone line is just one of dozens and dozens within this campus' telecommunication network. So, what's the big deal about this one? The article takes us through what does a room remodel have to do with irrigation systems southern NH.
Well, this particular phone line was used by the manager to connect via phone modem to the systems on-site control device, which managed all of the property's schedules. We're talking about a system that covered over 30 acres of landscape, a soccer field, a softball/baseball field, a putting green and almost 200 control valves; The entire system was offline because of this now compromised phone line. Losing communication with a site happens on occasion and could be due to a couple of different reasons.
Annual rainfall ranges between zero in the north and 100 mm in the southern parts, with mean summer and winter temperatures of 40 and 12 degrees celcius, respectively. River Nile is the main source of water crossing the state from south to north with a total length of 600 km. Underground water in the Nubian Basin which covers 70% of the Northern state's area with water depth ranging from 100-300 feet. Plant vegetation is very poor except in a narrow strip along both sides of the river Nile.
Now at this site, the CCU (the device with the phone modem) is located in an interior room at the campus. This room was the security room for several years, but that changed recently. Unbeknownst to the irrigation manager, this room was being remodeled. Which, of course, meant that the telephone line was unplugged? Problem identified.
In garden irrigation scheme the rain bird type of sprinkles is still very popular nowadays even of the most common garden you have. Well, that is for another type of sprinkling scheme. On the other hand, if you want to have a scheme that waters individual plants on the garden well you don't want to miss the other type of irrigation scheme, which is the trickle irrigation maneuver.
Surface versus sprinkler: The cost is one of the major items comprising the total cost of production in the Northern State. High prices of diesel used for irrigation, low efficiency of units and other problems associated with pumping water from the Nile and underground water are the main reasons. Pumping water is the main cost item leading to the known high cost of agricultural production in the Northern State.
Suffice it to say, but that is not an attractive option because that would take a whole day's worth of work at least. It would also mean trying to coordinate how much water each irrigation controller ran at any one time since they all shared two water sources. Too much water running at one time results in low water pressure, lousy coverage from the sprinklers and bad-looking grass.
Because of the systems hardware, previously programmed software and long-term management, this water pressure issue was readily dealt with on a nightly basis. Of course, that was before the phone line was shut down. Well, the first option chosen was to move the CCU to the large utility room in which the main telephone switching units are located. This meant there would be ready access to an unused telephone jack that could be easily activated and be available for the CCU modem.
