Head of development: Head of Lab. IIS, Ph.D., Bryakin I.V.

Purpose of development.

Ensuring high quality of products in various industries by recording in real time values of temperature and humidity in the active zone of process chambers and premises, as well as to maintain and control in the required range of changes in the parameters of technological processes.

A brief description of the development.

The automated complex is focused on simultaneous maintenance of several technological facilities in a multi-program mode of remote operation. It can be used as a basic module in systems of automated control and control of technological processes in chemical production shops, medical field, biopharmacological and woodworking plants, poultry farms, etc.

The composition of the complex is humidity sensors (DV), temperature sensors (DT), normalizing transducers (NP), switching device, adapters (A), ADC, DAC, discrete information input-output device (UVDI), alarm modes (AS), expander "General bus", control computer (UK), software.

Principle of operation: the functioning of the specialized complex is organized in the time-sharing mode, in which successively at each of the control objects a consistent survey of the state of the measuring sensors is carried out, and the subsequent analysis of the results of this survey with the adoption of appropriate decisions on the formation of the necessary control influences on the executive elements of the regulators of the working environment parameters.

Distinctive features of the complex:

developed system of pairing with a large number of external devices (measuring sensors);

• developed system of control and display of information;

• functioning in real time;

a large set of operations of logical transformation, search and systematization of measuring information;

• availability of a subsystem of hardware control of the emergency state of the object;

the structure of the complex is organized on the principle of consistent interface with the object of control;

• a synchronous mode of input and output of current measurement information to the control computer is carried out;

allows significant removal of the control object and measuring sensors from the control computer;

the possibility of functioning, both autonomously and with the direct participation of the operator (as an element of the system);

• oriented to operation in difficult conditions.

The software is implemented for IBM PC.

Functions to be performed:

collection and display of information on the current values of the parameters of the working environment;

control of electromechanical devices and actuators of the autoregulation system;

forecasting the state of the object of control by its characteristics and measured parameters;

• solving information problems and tasks of interaction with the operator;

automatic replacement and adaptation of operating algorithms to the changed conditions of the process of measuring the parameters of the working environment.
