Abstract: With the implementation of the 14th Five-Year Plan and the Made in China 2025 policy, China's continuous industrialization has put forward new requirements for the energy industry. As an important pillar of the energy industry, the intelligent construction of coal enterprises has become the key content and direction of the industry transformation and upgrading. Combining artificial intelligence, internet of things, big data, cloud computing and other intelligent technologies with traditional coal preparation process, realizing independent analysis, decision-making, learning, dynamic prediction and collaborative control of coal preparation plant has become the main goal of intelligent construction of coal preparation plant. In the process of intelligent construction, dahaize coal preparation plant has carried on intelligent transformation to its pressure filtration system. Through the research of intelligent filter press platform and integration of single filter press automation system, the self-judgment of the end state and the intelligent operation of the filter press are realized.
