1.2 X、Y、Z axis ranging
The system structure is shown in Figure 2. The black vertical line is the large traffic track, the
blue horizontal line is the large traffic, the white box is the small traffic, the red arrow is the direction
coordinate system, and the purple pattern is the hook. When driving, the big crane moves along the
Y-axis direction on the big crane track, and the small crane moves along the X-axis direction on the
big crane. At the same time, the hook moves along the Z-axis defensive line (that is, moves up and
down). Take carriage 1 as an example, install Tag1 on small carriage 1, Anchor1 on the big carriage,
install Tag4 (fixed equipment) at the end of the big carriage track, and install Tag5 on the hook 1.
During driving operation, X1 is obtained through mutual distance measurement between Anchor1
and Tag4, Y1 is obtained through mutual distance measurement between Tag1 and Anchor·, and Z1 is
obtained through mutual distance measurement between Tag5 and Tag, then the coordinates of hook
1 (X1, Y1, Z1). By analogy, the coordinates of hook 2 (X2, Y2, Z2), and the coordinates of hook 3
(X3, Y3, Z3). 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.
