Automation of closed water supply system for aquatic organisms

The article describes the automated closed water supply system based on industrial controllers OWEN, which allows creating the necessary fish habitat, increasing the population growth rate, rational use of production areas, conducting experiments on fish breeding, improving their characteristics. The need to develop the different modes of the system operation, in particular, temperature modes, oxygen concentration levels, feeding periods, etc., was taken into account when creating a software package written in the programming language FBD. The developed system includes lower, middle and upper levels. Control over the operation of the closed water supply system is carried out by monitoring. Fish feeding process is automated. Water purification is carried out in the non-stop regime, which decreases the amount of water used, lowers the costs and meets the principles of rational use of natural resources protecting the environment. It is possible to create the necessary dynamic modes of the system for the correct development of embryos and the effective development of various fish species and the possibility of using laser radiation of the required power. The system is controlled by a personal computer using the MasterSCADA package.
