Background
The distributed control system is a new generation of instrument control system based on microprocessor and adopting the design principle of decentralized control function, centralized display operation, and giving consideration to both sub-autonomy and comprehensive coordination. A distributed control system is called DCS for short, and adopts a structural form of multi-layer grading, cooperation and autonomy by adopting a basic design idea of control dispersion, operation and management centralization. Its main features are its centralized management and decentralized control. At present, DCS is widely applied to various industries such as electric power, metallurgy, petrifaction and the like, and is the core of production control.
In different DCS, the control devices of the process control stage differ from one another, such as process control units, field control stations, process interface units, etc., but they are of substantially the same form and can be referred to collectively as field control units FCUs. The process management stage, which consists of an engineer station, an operator station, a management computer, etc., performs centralized monitoring and management of the process control stage, and is generally referred to as an operator station.
In conclusion, the DCS plays an important role in ensuring the safety, stability, growth, fullness and excellence of enterprise production. However, in view of the fact that centralized monitoring and management of the process control level can only be completed in the operation station, when a CPU fault, a process channel fault and a power supply fault occur in the DCS system, the centralized monitoring and management can only be found when an operation maintainer inspects the data in the upper computer on site, and the operation maintainer is inconvenient to monitor the faults of the modules in the distributed control system efficiently.
