DESIGN SOFTWARE FOR THE AUTOMATION SYSTEMS COMBINED WATER TREATMENT USING UML NOTATION

A Kuznetsov, V. Shtepa, R. Kot, A. Morgol

 

The purpose of research – hold design automation software system combined water treatment plants.

Materials and methods of research. Basic technological equipment, which is scheduled for software design, intended for the treatment of industrial drains of production facilities. The technology allows using physical fields (ultrasound, magnetic field, light emission) control the supramolecular structure of aqueous solutions, yielding installing predefined parameters of water quality and/or composition of the extracted components.

The principle of operation is based on STW stepwise processing flow of the working medium in liquid and gaseous phase in three closed recirculation bypass circuits as a whole make up the system "user" - "water source".

The analysis of production testing, we establish that the planned information system has the following actors-people (according to the UML notation): engineer, the operator on duty.

 In addition they have the relevant actors external systems: measurement and analytical complex, a control unit, an intelligent power efficient management techniques, technical tools.

To simplify the structure of the conceptual model, we assume that the local automation system includes a global control unit and hardware (physical, biological, physical and chemical) merged into a single external system.

For efficiency and conservation performance "intelligent power" aggregates "computing unit" and "database".

"Engineer" conceptually defines the work of "intellectual bloc" and thus enjoys the results of his work. The relationship between the "engineer-technologist" and "operator on duty" is being implemented with the help of a bi-directional association. Multiplicity between classes defined according to technological analysis of considerations to ensure the automation of production processes.

The developed system with neural network control module, the hardware is implemented on the basis AtMega microprocessor, runs a production test on the company "Systems Engineering", where the STW provides wastewater treatment paint production to standards reuse production process: during the month of operating the energy efficiency of the process has improved by 16%, which confirms the adequacy of the designed control system structure and faithful selection of function blocks (connections between them).

Conclusion

Given the comprehensiveness and fuzziness of the input information in the software synthesis automation systems combined plants water treatment initially spend rationally design (modeling) the conceptual framework of the information system in the universal language UML, which will increase the reliability and structural stability created by the software.
