Embodiment Construction

[0028] Referring to the accompanying drawings, the present invention will be described in detail below.

[0029] Such as figure 1 As shown, the fully automatic storage system of an embodiment of the present invention mainly includes:

[0030] Three-dimensional shelf (100), aisle 1 (101), aisle 2 (102), aisle 3 (103), stacker mobile wireless node 1 (104), stacker mobile wireless node 2 (105), stacker mobile It consists of wireless node 3 (106), beacon node A (107), beacon node B (108), beacon node C (109), and beacon node D (110).

[0031] As can be seen from the figure, each roadway (101, 102, 103) has a stacker, which can perform deposit / take operations on the three-dimensional shelves (100) on the left and right sides, and the stacker moves horizontally in the roadway. For most storage systems, the length of the roadway is far greater than the height of the three-dimensional shelf (100), so the optimization of the speed regulation in the horizontal direction of the stacker...

Abstract

The invention discloses a method for improving the wireless positioning precision of a stacker. A four-side projection and positioning method is improved on the basis of a conventional four-side positioning algorithm by means of the linear motion characteristic of the stacker, so that the positioning precision is improved, and the complexity of the positioning algorithm is reduced. The method can be widely applicable to the fields such as a logistics storage center, a modern distribution center and the like, thereby being good in economic benefit and application prospect.

Description

technical field [0001] The invention relates to a method for improving the wireless positioning accuracy of a stacker, in particular to a four-side projection positioning method improved on the basis of the traditional four-side positioning algorithm by utilizing the linear motion characteristics of the stacker, so as to improve the positioning accuracy and reduce the positioning algorithm. The complexity of the method can be widely used in logistics storage centers, modern distribution centers and other fields, and belongs to the technical field of storage equipment. Background technique [0002] Fully automatic storage system refers to a system that stores materials in shelves in a unitized form without manual direct processing, and can automatically store / take materials. Fully automatic warehousing technology is the core of modern logistics technology. The stacker is the core handling equipment of the automatic storage system. It shuttles back and forth in the roadway to...
