[0002] Distributed control system (DCS system) is a new generation of instrument control system based on microprocessor, adopting the design principle of decentralized control function, centralized display operation, and taking into account the design principles of division and autonomy and comprehensive coordination. Distributed control system is referred to as DCS, which can also be directly translated as "distributed control system" or "distributed computer control system"; it adopts the basic design concept of decentralized control, centralized operation and management, and adopts a multi-level hierarchical, cooperative and autonomous structure; its main features are its centralized management and decentralized control; DCS has been widely used in various industries such as electricity, metallurgy, petrochemicals, etc.
[0003] Based on the above, the inventors have found the following problems: In a DCS system of a power plant, multiple control cabinets are usually required to cooperate step by step. When workers use the control cabinets for debugging or maintenance, they need to open the cabinet doors. After the debugging is completed, the cabinet doors need to be closed in time to protect the electrical components inside the control cabinet. However, in the actual operation process, after the debugging is completed, the workers may forget to close the cabinet doors, and the electrical components cannot be protected at this time.
[0004] Therefore, we have made improvements to this and proposed a misoperation alarm device based on the DCS system for power plants. Utility Model Content
