Building Automation in Positron-Emission Tomography Center

	Industry Building Automation SCADA/HMI Company Chelyabinsk PET Center Citation “One of the major benefits of using AggreGate SCADA/HMI was its cross-platform architecture that allowed us to install the system under Linux. The OS license savings, combined with the low price of the SCADA itself, allowed to decrease the overall cost of the project.” Hardware Schneider Electric TWIDO Series Controllers

Organizations

The Positron-Emission Tomography (PET) Center in Chelyabinsk is the first regional PET facility in Russia. The center was opened in 2010.

Informtekhnika JSC is specializing in automation, electric installation works, fire safety and security systems. During the last five years the company has successfully completed many system integration projects in power distribution, CCTV, access control, voice alarm systems, and other areas.

Challenges

The PET Center building is served by an Individual Heating Plant. Primary functions of the plant are:

• Distribution of water for heating, ventilation and water supply
• Boiling of water during external heat carrier shortages
• Blowing ventilation using damped or drained air
• Accurate control of temperature and humidity in the PET room
• Pressurization for the fire-prevention subsystem

The primary challenge of the whole project was automation of the heating plant operations and organization of remote monitoring and control.

Solution

All field-level procedures are performed by seven Schneider Electric TWIDO controllers, each of them serving a separate circuit. The AggreGate SCADA/HMI server acts as a supervising and monitoring agent.

AggreGate SCADA is installed on a Linux server and using PostgreSQL database for trend data storage. The server is connected to controllers via 100 Mbps Ethernet. All controllers are polled and configured using Modbus/IP protocol.

Benefits

• Linux compatibility
• Database-agnostic architecture, DBMS license savings
• Low per-controller license price
