Research Of Auto-sorting System Based On RTX And Multi-core Technology

Automatic sorting system is one of the basic facilities necessary for advanced distribution center, whose efficiency has great impact on the efficiency of delivery of the whole logistics system. Traditionally, auto-sorting system is managed by control software running on Windows based industrial computer (IPC). However, with the rapid increase of the amount and types of the goods to be sorted, traditional Windows based IPC system cannot meet the sorting requirements for accuracy and rapidness. Under the circumstances and combined with modern advanced computer technology of real-time operating system(RTOS) and multi-core processing, this thesis conduct a comprehensive analysis and research on auto-sorting system. A control model is proposed, which is based on Real-time Extension (RTX) operating system and multi-core processing technology, and the sorting efficiency has a big improvement with this model. Generally, the contributions in this thesis are as follows:First, this thesis conduct a detailed analysis of the various modules in auto-sorting system, and trace the theory and applications in the industry from the aspects of sorting tactics and sorting equipments. For the current problem of auto-sorting system cannot meet the requirement of sorting rapidness, a basic model for auto-sorting system is proposed, which is based on RTOS and multi-core technology, and from the overall, laid a solid foundation for the architecture design of auto-sorting system.Then, this thesis analysis the features of RTX and proposes a real-time auto-sorting model based on the advantages of RTX, such as the hard real-time characteristic, good compatibility etc...; Furthermore, this thesis studies multi-core technology based on RTX, research on techniques to speed up parallel computing on multi-core processor and combined with multi-core hardware structure and multi-core scheduling, proposes one control architecture to develop auto-sorting control software, which is based on parallel computing and multi-thread technology.After that, computer simulation is held based on the model for auto-sorting system. The results show that in condition of fast sorting for mass goods, compared with traditional model, RTX based auto-sorting system can greatly improve the performance of system responding time and ensure the stability and reliability, Also multi-core processing technology can make RTX based program strictly parallel execute and fully explore the advantages of multi-thread technology. The system architecture proposed for real-time auto-sorting system can better handle the issues of resources allocation between threads, improve system performance and have great practical values.
