In order to realize the whole process of manufacturing process industry to achieve the overall optimal in manufacturing process, the study selects the RDX manufacturing process of typical high explosives as a representative, establishing digital workshop by reference to production process characteristics. Then, from the workshop process flow, operation control, safety control, data management and application analysis of several aspects, constructing technology of digital workshop is researched. Accordingly, the commonness and special technology relating to the intelligent manufacturing of high energy explosive is extracted based on the existing technology and production engineering. Furthermore, the implementation methods of the key techniques applied in the digital workshop are expounded. The results show that constructing of digital workshop can realize the information perception of the whole process of workshop production and the digital workshop rapidly responds to the internal and external changes in the process. While ensuring the yield and quality of RDX products, the safety level in the manufacturing process is also improved.
