Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] Such as Figure 1-6 shown.

[0034] A UWB-based discrete manufacturing workshop material delivery car control system, which includes a workshop layout module, a host computer module, a material delivery car and a real-time positioning module, such as figure 1 shown. The workshop layout module consists of 8 basic functional areas, such as figure 2As shown, they are material area, lathe area, milling machine area, planer area, grinder area, fitter area, quality inspection room and finished product area. The coordinates of feature points in each basic functional area are calibrated by a unified coordinate system. An RFID reader is placed in the area to detect whether there is material delivery in the area and the type of material to be delivered; the upper computer module includes a communication module, a speed control module, a motion control ...

Abstract

A UWB-based discrete manufacturing plant material delivery cart control system comprises a plant layout module, an upper computer module, a material delivery cart, and a real-time positioning module. The plant layout module is simplified and extracted according to the basic requirement of a discrete manufacturing plant, and is used to map the whole discrete manufacturing plant. The upper computer module is used to realize motion control, real-time positioning and trajectory tracking of the material delivery cart, and display the whole process of material delivery in real time. The material delivery cart completes the whole process of material delivery. The real-time positioning module realizes real-time positioning and tracking of the material delivery cart. By adopting the system of the invention, the flexibility of discrete manufacturing plant material delivery can be enhanced effectively. The position and motion trajectory of the material delivery cart can be displayed in real time, and the process of material delivery is visualized. Each basic function area identifies the types of materials and tracks the materials through an RFID reader. The system has high popularization value for discrete manufacturing plants.

Description

technical field [0001] The invention relates to a logistics technology, especially a material distribution technology in a single-piece or small-batch discrete manufacturing workshop, in particular a control system for a UWB-based material distribution trolley in a discrete manufacturing workshop. Background technique [0002] In a discrete manufacturing shop, the production process is usually decomposed into many processing tasks. Each task requires only a small amount of processing resources. Within the enterprise, equipment with similar functions is generally built into some production organizations (departments, sections or groups) according to space and administrative management. Within a production organization, workpieces require different types of processing from one work center to another. In discrete manufacturing, the processing route and the use of equipment are very flexible, and the location of production equipment needs to be reasonably arranged according to...
