Design and realization of pond eccentric hydrodynamic equipment control system

Abstract:

Water flowing is the basic condition for the water purification of pond. High efficient water hydrodynamic forming and control are of great value. The eccentric hydrodynamic equipment provides a good balance between the oxygenation and hydrodynamic forming. Based on the requirement of pond fine ecological factor regulation, the control system hardware system including sensor, data processing, storage, output and wireless communication components is constructed. Control algorithm based on oxygenation and hydrodynamic parameters is developed, which also contains the low-voltage sub-system self-detection and high-voltage sub-system checking function. By real time supervision of the dissolved oxygen and combined with the covering range in different power conditions, the control system achieves adaptive power output control and reaches a comprehensive effect from the view of oxygenation, hydrodynamic and energy cost. Based on the pond ecological factors and the requirement of meeting the pond oxygen demand, the practical experimental comparison results between the eccentric hydrodynamic equipment with the designed control system and other oxygenation equipments show the power flow in the new equipment decreases more slowly, and the hydrodynamic effect of the same area is dramatically increased. It can save about 24% of energy cost. The above results lay a solid foundation for the wide application of eccentric water power equipment.
