System Structure:
The distributed control system is designed with standardization, modularity, and serialization, consisting of a centralized management section, decentralized control and detection section, and communication section. The centralized management section includes management computers, engineer stations, and operator stations. The management computer is used for information management and optimized control of the system, engineer stations for configuration and maintenance, and operator stations for monitoring and operation. The decentralized control and detection section includes control stations, monitoring stations, or field control stations, which are used to control and detect the connection of the communication section to various distributed parts, completing the transmission of data, instructions, and other information.
System Features:
Each work station independently completes designated tasks such as data collection, processing, calculation, monitoring, operation, and control, which are reasonably allocated. The control functions are comprehensive, with rich control algorithms, integrating both continuous and batch control, ensuring high system controllability.
2. User-friendly, intuitive display, and excellent monitorability.
3. The Human-Machine Interaction System is practical and straightforward. It features rich interface displays such as process flow diagrams, parameter tables, historical trend charts, real-time trend charts, information alarms, fault analysis, and operation guidance.
4. The DCS control system can be programmed on a laptop within a dedicated software environment. Minor parameter adjustments and program changes sent to the DLC will not disrupt ongoing operation, and PLC internal variable parameters can also be updated online. This facilitates program maintenance and inspection.
5. Modular system architecture, with open, standardized, and modular hardware and software design, flexible configuration, good adaptability, and scalability.
6. Real-time collection, analysis, recording, monitoring, and operational control of process parameters, online modification of system structures and configuration loops, and on-site maintenance of local faults, with high system availability.
7. Utilizes system architecture fault-tolerant design, ensuring system integrity during any unit failure, and maintaining local station operations in case of global communication or management station failure.
8. Equipped with accident alarm, dual measures, and online fault handling, the system boasts high reliability and safety.
