Aquaponics is a food-production system that farms fish and plants together in a symbiotic cycle. Fish produce waste that serves as a natural fertilizer for the plants and in turn, the bacteria that reside in the roots of the plants clean the water for the fish. All of this takes place within the nitrogen cycle that lies in the foundation of every aquaponic system. Once an aquaponic system is designed and build for a particular size, the system runs continuously and most of the system parameters (such as grow bed flood level, flood and drains times) are fixed and cannot be easily changed or controlled by the user. myRIO Aquaponics provides that control. myRIO Aquaponics allows the user to tap into the aquaponic cycle and turn a fixed-parameter mechanical system into a flexible, electronically- controlled dynamic system that can be tuned and customized for a particular aquaponics application. With myRIO Aquaponics the user can take full control of the aquaponic system parameters and tune the system to maximize fish and plant harvest at a fraction of a cost of an industrial control system. In addition, myRIO Aquaponics provides continuous monitoring of the health of the system and allows the user to spot the potential problems (e.g. acidic pH levels in the fish tank) early on and take the necessary action. Moreover, with myRIO Aquaponics, an aquaponic system doesn't have to run continuously. The user can adjust the timing of the aquaponic cycle for optimal harvest, as well as balanced power consumption. In addition, if necessary the system can be remotely controlled and monitored through the Internet. The current design, allows the user to monitor the following parameters of an aquaponic system:
• Fish tank temperature (TMP1)
• Fish tank water pH level (PH1)
• Fish tank water level (UTR2)
• Pump flow rate (FLW1)
• Grow bed water level (UTR1)
In addition, the user can set and control the following system parameters:
• Fl - Grow bed flood level set point (inch)
• Ft -Target flood level time (s)
• Pt - Pump OFF time (s)
• Ml - Fish tank minimum water level (inch)
• T1 - Fish tank Temperature Threshold (Fahrenheit)
Once the system parameters above have been set by the user, the LabVIEW code running on the myRIO real-time target automatically controls the operation of the heater and the pump in the aquaponic system to meet the user-defined constraints.
