Digitalized manufacture workshop material real-time distributing system based on Ultra Wideband (UWB)

Abstract

The invention discloses a digitalized manufacture workshop material real-time distributing system based on an Ultra Wideband (UWB), comprising a digitalized manufacture workshop visualized precise laying module and a digitalized manufacture workshop material real-time distributing and monitoring module, wherein the digitalized manufacture workshop visualized precise laying module maps a relevant manufacture resource of a digitalized manufacture workshop to a computer in a uniform coordinate system and realizes the digitalization and the visualization of physical manufacture workshop layout; the digitalized manufacture workshop material real-time distributing and monitoring module comprises a material distributing trolley path planning and navigating submodule and a material distributing trolley real-time positioning and tracing submodule; the material distributing trolley path planning and navigating submodule plans a material distributing path of a digitalized manufacture workshop and carries out path navigation on the workshop material distributing process on the basis; and the material distributing trolley real-time positioning and tracing submodule realizes the real-time positioning and tracing on a material distributing trolley by applying a UWB wireless positioning technology. The digitalized manufacture workshop material real-time distributing system can effectively reduce the semifinished product stock, improve the instantaneity and the accuracy of material distribution and the production quality of a workshop and provide reference for realizing on-time production of the digitalized manufacture workshop.

Description

technical field [0001] The invention belongs to the technical field of advanced manufacturing and automation, and relates to a method and system for real-time distribution of materials in digital manufacturing workshops based on ultra-wideband wireless technology (UltraWideband, UWB). Background technique [0002] In the production process of the digital manufacturing workshop, material distribution is a very important link. With the personalized development of market demand, the production mode of enterprises has changed from single-variety mass production to multi-species small-volume production, especially as the concept of just-in-time (JIT) has been gradually adopted by manufacturing enterprises. Popularized and applied, the material distribution mode of "near-zero inventory production" and "on-demand delivery" has become one of the key means for manufacturing enterprises to reduce inventory costs and improve production efficiency. This makes the material distribution ...

AI Technical Summary

Problems solved by technology

[0004] 1) Most of the material distribution in the workshop is based on the experience of the distribution personnel, lack of planning and guidance for the material distribution tasks and distribution routes in the workshop, and there is no scientific basis for the material distribution in the workshop

[0005] 2) Lack of effective methods and means for real-time positioning and tracking of digital manufacturing workshops, real-time positioning and tracking of material distribution vehicles cannot be realized, resulting in the inability to complete the visual monitoring of the material distribution process

Due to the above advantages of UWB technology, the ultra-wideband real-time positioning system developed by the University of Cambridge has been used in the Sellafield nuclear power plant in the UK to provide positioning services for employees; Harry K.H.Chow has applied UWB technology to warehouse operation management to monitor the warehouse operation process Tang En Technology has applied UWB technology to indoor personnel positioning, warehouse positioning management system, and production automation auxiliary system; but how to use UWB technology to realize real-time positioning of delivery cars in digital manufacturing workshops, so as to realize real-time delivery of workshop materials has not yet been studied. and application, but the above research results provide a good reference for the implementation and application of the present invention
