Abstract: Abstract: This paper mainly introduces intelligent production management such as data form， calculation method and fault judgment for 6 units，i.e. coal blending & cokemaking，cooling and exhauster，ammonia stripping，desulfurization，ammonium sulphate production and crude benzol removal. Application method of the platform is also given. This intelligent production management platform based on balance calculation could realize real-time data collection to complete the calculation of material balance，heat balance and water balance，analyze the troubles in operation so as to achieve optimized production，energy conservation and emission reduction.

Key words: Key words: Material balance, Heat balance, Water balance, Intelligent coking plant production, Production management platform
