There provides an auxiliary structure for floating and sinking the whole offshore wind turbine with suction bucket foundation(s), which includes an upper bracket floated on water and a lower bracket sunk synchronously with a support structure. The upper bracket includes upper floating boxes; upper cross-connectors each of which is fixedly connected to the upper hoop and a corresponding upper floating box; and an upper hoop configured to sleeve on an outer side of the support structure. The upper bracket and the support structure are relatively moved in an up and down direction, and are connected in a manner of limiting position. The lower bracket includes lower floating boxes, a bottom of each of which is adjustable in height; lower cross-connectors each of which is fixedly connected to the lower hoop and a corresponding lower floating box; and a lower hoop that holds the support structure tightly.

The embodiments of the present disclosure provide a system for calculating a regional crowd movement and a method thereof. The system is applied to a target monitoring environment, a plurality of key travel nodes are planned in the target monitoring environment, and the system includes radio frequency labels deployed on pedestrians, calculation apparatuses deployed at the key travel nodes and a plurality of directional antennas. The directional antenna is configured to, when driven by the calculation apparatus, send a read-write signal to the radio frequency label in a coverage region; the directional antenna is further configured to forward a radio frequency signal simultaneously reflected by the radio frequency label at the time of obtaining the read-write signal to the calculation apparatus; the calculation apparatus is configured to, based on a tempo-spatial distribution circumstance of the radio frequency signals in the region.
