DEVELOPMENT OF A SYSTEM FOR MONITORING THE PARAMETERS OF THE ENVIRONMENT DURING SHRIMP BREEDING

Abstract

Today, information and measurement systems are used in almost all industries where it is necessary not only to measure the parameters of the object of control, but also to absorb the process in the object, in order to respond in a timely manner to changes in controlled parameters. Monitoring changes in the parameters of the object of control is an urgent task of modern measuring technology. When developing an information and measurement system that performs the collection, processing and transmission of information, one of the main tasks is to maintain the metrological reliability of such a system and its economic feasibility. The information and measurement system must be competitive in comparison with existing analogues. One of the promising ways to increase metrological reliability is the use of modern high-precision primary measuring transducers, as it is the analog part of the measuring channel that makes the largest contribution to the total measurement error. The article proposes to develop a system of control of environmental parameters in shrimp breeding on the basis of modern element base, which allows not only to measure with high accuracy the microclimate parameters in the shrimp tank, but also to influence the object of control through actuators. These devices switch on the water heating and aeration system if necessary. Determining the need to influence the environment is determined by the operation "comparison of the current value of the control parameter with the set value". This operation is possible thanks to the software product that is loaded into the microcontroller. The article presents a block diagram of the developed information and measurement system, electrical schematic diagram and analysis of errors in measurement channels. It is noted that the measurement error on each of the channels does not exceed 1.5%.
