The crane system is generally used in large crane warehouses to determine the location of the
materials to be lifted by distance measurement, which is convenient for the management of
warehouse materials.
In the following descripiton,the UWB gateway(UG-230) is configured in anchor mode and the
UWB Tag(UT-207-HO) is configured in tag mode.The gateway is installed on the line crane through
mounting ears and configured to work mode through the RS485 port.
1.1 X、Y axis ranging
The system structure is shown in Figure 1. The black vertical line is the big traffic track, the blue
horizontal line is the big traffic, the white box is the small traffic, and the red arrow is the direction
coordinate system. When driving, the big crane moves along the Y-axis direction on the big crane
track, while the small crane moves along the X-axis direction on the big crane. Take carriage 1 as an
example. Tag1 is installed on small carriage 1, Anchor is installed on big carriage 1, and Tag4 (fixed
equipment) is installed at the end of the big carriage track. During driving operation, X1 is obtained
through mutual distance measurement between Anchor1 and Tag4, and Y1 is obtained through
mutual distance measurement between Tag1 and Anchor·, then the coordinates of small driving
vehicle 1 (X1, Y1). By analogy, the coordinates of car 2 (X2, Y2), and the coordinates of car 3 (X3,
Y3). In general, Anchor transmits the coordinates to PLC (provided by the integrator) through the
485 bus, and the PLC transmits the data to the management platform.
