Public Aquatic Habitat support SystemSpeakers:1st Gabor Kondas2nd Schuyler Wu3rd Howard Li4th Kevin Seng

Aquarium CarePublic aquariums is a major exercise in logistics.Water conditions must perfectly maintained so not to adversely affect the specimens (i.e. the fishes).Upkeep requires around the clock attention from a large aquarium staff operating in shifts.A large staff would mean higher expenditures for the aquarium budget.Human error is more likely to occur.GoalsTo reduce the frequency of human errors in the fish keeping of public aquariums.To maintain consistent quality tank environments at all times.To reduce the need for a large aquarium staff to maintain the facility 24/7. The Role of PAHSSThe Public Aquatic Habitat Support System is a software system that automates much of the effort currently performed by the staff. It is able to rapidly respond to abnormal tank conditions and take appropriate actions to correct them.

FeaturesReal time monitoring of aquarium tank conditions.Instant condition correction when current conditions exceed or fall below optimal tolerances.Automatically calculates tank conditions based on the species present in the tank.Instant notifications in the event of faulty equipmentScalability to manage a few large tanks or many smaller ones and vice versa.

The user is given the ability to override the computer determined optimal settings if need be.Temperature RegulatorType of species in each tankHabitat informationTemperature readings of each tankNotificationsDesired temperature of each tankStart heaterStart chillerHeat waterCool waterStop heaterStop chillerTemperature readings in each tankTemperature Regulator RequirementsRequirements Related to Design Element 2.2: Temperature RegulatorRequirement No.Requirement Description3.2.1Monitoring3.2.1-1PAHSS TR shall take real time readings from temperature sensor equipment.3.2.2Settings3.2.2-1PAHSS TR shall calculate optimal water temperature, tolerances, and rate of temperature change based on the species present in the tank and the habitat conditions of each species.3.2.2-2PAHSS TR shall allow the user to adjust the desired water temperature based on input received from the MI.3.2.2-3PAHSS TR shall allow the user to adjust the rate of water temperature change based on input received from the MI.3.2.2-4PAHSS TR shall allow the user to initiate an immediate heating based on input received from the MI.3.2.2-5PAHSS TR shall allow the user to initiate an immediate cooling based on input received from the MI.3.2.2-6PAHSS TR shall allow the user to shutdown the heat pump based on input received from the MI.3.2.2-7PAHSS TR shall allow the user to start up the heat pump based on input received from the MI.3.2.2-8PAHSS TR shall allow the user to start the heater based on input received from the MI.3.2.2-9PAHSS TR shall allow the user to start the chiller based on input received from the MI.3.2.3Control3.2.3-1PAHSS TR shall command the chiller to cool the water if the temperature readings are above the optimal settings or user desired settings.3.2.3-2PAHSS TR shall command the heater to heat the water if the temperature readings are below the optimal settings or user desired settings.3.2.3-3PAHSS TR shall command to the heater to shutdown based on input received from the MI.3.2.3-4PAHSS TR shall command to the chiller to shutdown based on input received from the MI.3.2.4To Display3.2.4-1PAHSS TR shall send water temperature sensor data to the MI for display.3.2.4-2PAHSS TR shall send water temperature settings to the MI for display.3.2.4-3PAHSS TR shall send a confirm action notice to the MI for display when the user initiates an immediate heating.3.2.4-4PAHSS TR shall send a confirm action notice to the MI for display when the user initiates an immediate cooling.3.2.4-5PAHSS TR shall send a confirm action notice to the MI for display when user desired temperatures exceed the upper tolerances of the optimal calculated settings.3.2.4-6PAHSS TR shall send a confirm action notice to the MI for display when user desired temperatures fall below the lower tolerances of the optimal calculated settings.3.2.4-7PAHSS TR shall send a confirm action notice to the MI for display when user desired temperature changes exceed the temperature changes of the optimal calculated settings.The Chemistry RegulatorThe chemistry regulators function is to maintain a balance of salinity, pH, and certain water solutes within each of the tanks and the tank reservoirs.

tolerancesThe temperature regulator identifies the abnormal conditions.The module will then send a command to the heater to warm up the water.The temperature regulator will then write the action to the action log.Condition History2.5 Filtration Regulator2.1 Management Interface2.6 Equipment MonitorAction History2.2 Temperature Regulator2.3 Chemistry RegulatorSpecies DatabaseTank StockSpecies
