SIMULATION OF AUTOMATED MONITORING SYSTEMS
KEY

Currently,
the industrial enterprises are becoming increasingly urgent task of improving
the process of production management. It is particularly important solution to
this problem for those businesses or areas where the state parameters of
production decisive influence on the quality of products, and in some cases -
to life and health of the consumer (in the food industry, in homes or in the
manufacture of pharmaceutical products). Given a constant struggle for cost
reduction, production efficiency and competitiveness of their products, it is
necessary to ensure the correctness of managerial decisions and the adequacy of
the current state of the process. This can’t be achieved without the use of
timely and reliable information about the object at each level of production.
In addition to informed choice of hardware - sensors, communication lines,
transmitters - play a great role and software data. [1]

Simulation
model - is a universal tool for studying complex systems, which is a
logical-algorithmic description of the behavior of the system components and
their interaction rules that display a sequence of events that occur in the
simulated system.[2]

1 - The general scheme of the hardware of the automated monitoring systems
The
model is a complex set of software and hardware. The hardware part includes in
its membership the measuring equipment, real-time controller and temperature
sensors.
To
create such system is used modeling. However, regardless of the type developed
model, its purpose is to replace the complex original object and how can a more
accurate reflection of its basic properties.
The
proposed method of using simulation in solving technical problems of automation
of complex objects allows for the development of control systems, regardless of
the degree of readiness of physical objects. That is, when we do not have the
ability to use real devices, then we can replace them with affordable low-cost
electronics. A system is proposed for this use SCI resistor as a temperature
sensor.
The
essence of this method lies in the fact that the sensor is used as a type of
resistors SCI. That is, based on resistors sensors react to light, temperature
or pressure. Most of these are included as part of a voltage divider, which
varies depending on the resistance of resistors under the influence of changing
external factors. Resistance decreases and increases due to temperature.
Proposed
simulation model of automated accounting and control system can be used for
educational laboratories of creation of such
complex networks. The
real temperature sensors are costly for training purposes. In order to study and analyze the creation of such an automated system
in the conditions of educational laboratories as a sensor can be used thermal
resistors.
The
article revealed aspects of the design and implementation of simulation models,
in particular of such models, which replace the original object at its input
and output signals: signal control elements of technological equipment and
sensor signals, reflecting changes in process parameters.
