Automated Control System for the Process Thermal Conditions

The system's purpose is to control the functional condition of the cooled equipment, as well as to control and analyse the thermal conditions of the manufacturing process.

The system's functions are:

to measure the temperature in the range from -50 to +200 С;
to accumulate and process the received values;
to record the events and accumulate the statistics;
to record the prehistory of emergency conditions development and to retain it for further processing and analysing;
to generate control signals according to the processing effect;
to indicate and generate the processed signals in the form suitable for the customer.

Hardware:

temperature sensors produced by RPC "Donix" with the measurement accuracy of 0,1 degree;
programmable controllers with 8 access ports produced by RPC "Donix";
personal computer (industrial version is possible);
uninterruptible power supply.

The controllers used in the system are of damp- and dustproof construction. The operating temperature range of the controller lies within -20 and +85 С. The length of communication lines between the controller and the PC makes at the most 1000 m.

The system can process up to 255 controllers with the total of up to 2040 access ports. The time required to poll one controller makes at the most 0.1 second.

Software: software environment, written in "С++" language, functioning in the operational system MS DOS.

The system is implemented:

Blast-furnace #3 of Alchevsk Metallurgical Works "System for monitoring the blower nozzles failure"

Blast-furnace #1 of Makeevka Integrated Metallurgical Works "System for monitoring the thermal conditions of blast-furnace hearth and blast-furnace bottom coolers"
