AI Technical Summary

Technical Problem

Existing technologies fail to fully utilize the dynamic information presented by go-karts on the track, resulting in passive control of the link management. In particular, the signal environment exhibits highly nonlinear characteristics during high-speed driving, affecting communication stability.

Method used

By acquiring the dynamic status information of the go-karts and combining it with the geometric constraints of the track, trend indicators are calculated and mapped to the UWB base station link coverage structure to predict link quality, adjust channel allocation, communication power and path priority, and achieve dynamic link control.

Benefits of technology

Before the go-kart enters a sharp bend or a highly obstructed area, channel and power adjustments are made to avoid communication instability and achieve continuous, low-jitter communication link management.

Abstract

The invention discloses a dynamic link control system and method based on positioning and motion trend analysis, and belongs to the technical field of link control, and the method specifically comprises the steps: obtaining the dynamic state information of a kart, and obtaining the dynamic state information of the kart based on the preset geometric constraint information of a racing track and the current state change rate of the kart; direction offset calculation, curvature change judgment and boundary proximity judgment are carried out on the dynamic state information, a trend indication quantity is generated, the trend indication quantity is mapped to a link coverage structure of a UWB base station, the interference level, the blocking probability and the time delay change trend of a corresponding link are calculated according to the area where the kart drives in, and the dynamic state information of the kart is obtained. Forming a link quality estimation result, and regulating and controlling channel allocation, communication power and a priority communication path between the kart and the UWB base station according to the link quality estimation result; according to the invention, the method achieves the sequential management of link resources in a multi-base-station coverage environment, and enables a kart to maintain a continuous and low-jitter communication link in a high-speed driving process.
