In view of the current situation, the paper elaborates on the development history of distributed electrical control systems, and analyzes their advantages and disadvantages from multiple perspectives. A complete architecture is proposed to meet user requirements, which includes modular architecture, optimized communication protocols, and rational data transmission strategies. Subsequently, each module’s purpose and operation principles are explored, covering distributed control, data transmission, data acquisition, and other related modules. Finally, experimental verification is conducted, and the results demonstrate the feasibility and scalability of the proposed design. This research is of great significance in improving the performance and reliability of electrical control systems and provides valuable references for engineering practices in related fields.
