Abstract

This invention discloses a collaborative planning method and system for patrol vehicle platooning based on blockchain reputation consensus, relating to the field of collaborative control technology. The method includes: obtaining the actual trajectory accuracy and consensus response latency of each patrol vehicle through a smart contract, calculating a comprehensive trust metric, and storing it in a distributed ledger; using the height of the newly generated block as a synchronization pulse signal, each patrol vehicle independently executes a particle swarm optimization algorithm locally to obtain its individual optimal solution based on the previous round's global optimal solution; the smart contract automatically eliminates inferior solutions with reputation below a threshold, and uses the trust metric as weight for on-chain consensus to generate a new global optimal solution and a new block; each vehicle synchronously extracts the global optimal solution, and uses a cubic Bézier curve to smooth the waypoint sequence, ultimately transforming it into a control flow signal used to control the underlying execution of the vehicles. This achieves complete immunity to malicious node data, ultimately achieving secure collaborative patrol with zero blind spots.
