Automated Feeding Control System
The focus of DCS has always been on control, and it uses "decentralization" as the key word. However, modern development focuses more on the comprehensive management of system-wide information. In the future, "integration" will become its key word, and it will develop in the direction of realizing the comprehensive automation of the control system, operation system, planning system and management system. Optimal control rises to production scheduling, operation management, and even strategic decision-making at the highest level, forming a flexible and highly automated management and control integration system.

Distributed control system is referred to as DCS, which can also be literally translated as "distributed control system" or "distributed computer control system". It adopts the basic design idea of decentralized control, centralized operation and management, and adopts a multi-layer hierarchical, cooperative and autonomous structure. Its main feature is its centralized management and decentralized control. At present, DCS has been widely used in electric power, metallurgy, petrochemical and other industries. DCS usually adopts a hierarchical structure, as shown in Figure 3.1, each level consists of several subsystems, each subsystem achieves several specific limited goals, forming a pyramid structure. Reliability is the life of DCS development. There are three main measures to ensure the high reliability of DCS: one is to widely use high-reliability hardware equipment and production processes; the other is to widely use redundancy technology; the third is to widely implement software design. System fault-tolerant technology, fault self-diagnosis and automatic processing technology. The MTBF of most distributed control systems today can reach tens of thousands or even hundreds of thousands of hours.
