1.3 Z axis ranging
The system structure is shown in Figure 3. The white box is a small driving car and the purple
pattern is a hook. When driving, the hook moves along the Z-axis direction (ie: moves up and down).
Take drive 1 as an example, install Tag1 on trolley 1 and Tag4 on hook 1. During driving operation,
Z1 is obtained by mutual distance measurement between Tag1 and Tag4, then the coordinate of hook
1 (Z1). By analogy, the coordinates of hook 2 (Z2), the coordinates of hook 3 (Z3). In general, Tag1
(Tag on the trolley) transmits the coordinates to the PLC (provided by the integrator) through the 485
bus, and the PLC then transmits the data to the management platform.
