DCS

DCS (Distributed Control System) is an industrial automation system that uses a microprocessor as its core and adopts the design principle of 'distributed control and centralized management.' It connects multiple control units (such as controllers and I/O modules) distributed across the production site to a central operator station via a communication network, enabling real-time monitoring and control of the continuous production process.

Core idea: Control functions are distributed, while operation and management functions are centralized, balancing autonomy and comprehensive coordination.

Technical Foundation: The 4C technologies integrating Computer, Communication, CRT display, and Control.

Hardware components:

Field control station: Executes real-time control algorithms, including I/O cards (for acquiring signals such as temperature and pressure) and a processor unit (PCU).

Operator station: A human-machine interface used for monitoring and manual intervention.

Engineer's Station: System configuration, maintenance, and control strategy development.

Historical site: Stores process data and supports trend analysis.

Software part:

Control algorithms (such as PID, cascade control), configuration software (for system configuration), and database management tools.

KPT has extensive experience in the power, petrochemical, water treatment, and compressor control industries. Main applications include:

Data acquisition: Converting analog signals from the field into digital signals via I/O modules.

Process control: The PCU processes data according to a preset algorithm and outputs control commands (such as adjusting valve opening).

Monitoring and Alarm: Real-time display of process parameters, triggering alarms when limits are exceeded.

Centralized Management: Supports multi-level access control for production scheduling and optimization.

KPT provides efficient and stable automation solutions for the process industry by combining decentralized control with centralized management. In the future, with the development of intelligent and cloud-edge collaborative technologies, it will further evolve towards green, low-carbon, and cybersecurity directions.
