Production Management System for Small and Medium Sized Manufacturing Enterprises

With industrial internet increasingly used in manufacturing industry, the traditional manufacturing industry can no longer meet the needs of the development of manufacturing and producing, which brought both an opportunity and a huge challenge for small and medium-sized manufacturing enterprises. After investigations and consultations with many small and medium-sized enterprise, developed a set of production management systems for small and medium-sized enterprises. The system includes three layers: physical layer, network layer and system layer. At the physical layer, field data is collected through photoelectric sensors and a model is established to found high-precision sensor node method. At the network layer, ZigBee wireless transmission network protocol is used to develop a wireless transmission module with strong anti-interference ability and data confidentiality. At the system layer, a production management system is developed according to characteristics of mobile terminals and PC in order to achieve equipment failure repair, alarm message push and other functions in the mobile terminal and to realize visual board and other functions. The system and technologies proposed is important for information-based manufacturing industries.
