[Abstract]:In discrete manufacturing workshops, due to the lack of location information of production factors, workshop production and management often face difficulties in in-process management, material distribution lag, production factors difficult to find and so on. With the further development of manufacturing technology, real-time positioning technology has been gradually applied in discrete manufacturing workshops, resulting in a manufacturing model based on location services. In this paper, the application of real-time positioning technology in discrete manufacturing workshops is studied, which provides location-based services for production and management personnel, and improves the visualization and information management level of discrete manufacturing workshops. The research contents and main results are as follows: (1) the real-time positioning technology based on RFID and UWB is studied. Starting with the demand of discrete manufacturing workshop for real-time positioning, combined with the demand of production factor location, the composite positioning scheme based on RFID and UWB is constructed. Secondly, the collected real-time data of UWB and RFID are processed, respectively. It provides reliable data support for upper layer applications. (2) the holographic map of discrete manufacturing workshop is studied. Firstly, the basic characteristics and organization framework of the map are described in detail. Secondly, the data model is studied on the basis of the analysis of the manufacturing field data, and the organization form and analysis operation of the model are expounded. The construction process and location service of the map are described in detail. (3) the material distribution path planning of discrete manufacturing workshop is studied. Based on the holographic map and the constraints of material distribution problem, the path planning process of material distribution is designed, the global planning model and local planning strategy of material distribution path are elaborated in detail, and the path planning algorithm is studied. The material distribution process is optimized. (4) A real-time positioning application prototype system is developed. The system framework and function module are designed, the hardware platform construction process is described in detail, the prototype system development is completed, and the feasibility and effectiveness of the system are verified.
