ABSTRACT

  INTRODUCTION
   The main areas of engineering professionals in the field of electric drive and automation is designing, construction and operation control systems, power converter devices, measuring systems and more. Implementation of management systems of modern electric drives based on the useing of microprocessors and computers, which present a professional qualification to engineer a number of additional requirements to master which are the new information technologies engineering work. Successful graduates of technical universities competition in the labor market is possible only at sufficiently high level of theoretical and practical engineering training. As the requirements for employers to quality training continuously strengthened, it substantially increases the role of laboratory practical work in the educational process.
  Working with microcontroller systems control actual hardware is available in limited volume of laboratory works and the degree of design, due to the high cost of equipment and the small number of educational booths. Nowadays, the use microkontrol modules in practical laboratory and course design has become more affordable because there inexpensive sets of specialized companies that allow students to use them as separate devices, and systems in stock.
  The development of modern computer technology allows to implement complex control algorithms in real-time. Digital control systems have several advantages compared with analog, resulting in simplicity and flexibility of control algorithms. Therefore, knowledge of experts in this direction is extremely important, and to form their necessary practical skills are essential in the learning process using modern specialized laboratory equipment.
  LITERATURE REVIEW
  Modern education in Ukraine aimed at realization of high capacity computer and telecommunication technologies that allows new forms of educational process, greatly improve training and, above all, self&ndashefficacy of students, the share of the total volume of training is constantly increasing.

  An important part of the educational process of all specialties are electromechanical laboratory practice. Development of laboratory facilities must go through the creation of new modern laboratory facilities and physical models. Latest computer technologies allow ample opportunity for various experiments on mathematical models and real.
  One effective means of studying processes of functioning of electromechanical systems and automation systems, intensification and improvement of research are engineering work is research based on computer modeling that ensures efficient calculation of steady and transient modes in regular and abnormal operating modes. Methodological and methodical basis for mathematical modeling of devices based on power electronics and microprocessor technology is a systematic approach, simulation and analytical modeling. Modeling difficulties caused by their heterogeneous physical nature, topology and mathematical complexity of the models, the necessity of multilevel modeling. The disadvantage of this approach is the study of virtual models that do not give a clear understanding of the structure of real system and not allow to get practical experience working with hardware.
  Development of the complex was performed with the following requirements:
  1. data from two channels simultaneously, synchronization and logging to file input and output signals;
  2. provide the required output voltage harmonic structure and the possibility of change;
  3. opportunity to observe the harmonic structure of power in real time;
  4. simple circuit implementation and the ability to use speed control algorithms on microprocessor element basis.

  The complex contains in itself the following elements:
  1. personal computer – implementing automation functions for diagnostics, software interface, data collection, processing results and changing weights three harmonic voltage so as to maintain a harmonious composition of electrical power to the load;
  2. pulse–width converter implemented on a microcontroller, power transistors and power transistors and drivers designed for supply voltage;
  3. unregulated dc voltage integral transformer &ndash Power sells power driver transistors.
  As the basic equipment used to implement complex demonstration booth CC&ndashLink Demo&ndashcase company Mitsubishi. The stand is designed for remote control of discrete objects and continuous and has several advantages:
  1. multyprotsesornyy work;
  2. The large number of communication interfaces;
  3. open architecture construction.

  Based on the experience of these and other works necessary to develop software and hardware for the study of thermal processes as the most convenient for implementation. The stand must meet the following requirements:
  1. Physical model.
  2. Availability of equipment and PLC.
  3. Communication equipment and PLC with PC.
  4. Manage PC.
  5. Availability of software.
  6. Establishment of a heating and cooling
  DEVELOPMENT OF SCHEME

  In developing the functional scheme, it is necessary to determine the basic elements that make up its membership. Please specify the number of such elements, their purpose and functional capacity. These include:
  1. Temperature sensor
  2. KVP or PLC
  3. Trasformator
  4. Regulators
  5. Cullers
  Using these requirements and those that unique to each system component separately, was selected elements of automation, which in the future will be installed on the stand.
