Research on Quality Improvement and Safety Measures of Highway Pavement Construction by Unmanned Aircraft Swarm Operation Based on Optimal Control Theory

Aiming at the traditional pavement construction, there are problems such as poor construction conditions, limited quality inspection methods, backward control mode and incomplete management means.In this environment, the project in this paper (Gansu Road and Bridge Anlin Pavement Second Standard Project) uses multi-objective particle swarm optimization algorithm to establish a multiobjective machine group optimization configuration model based on quality constraints under the schedule -cost, and the first time to quote asphalt pavement to carry out the intelligent construction of unmanned machine group in Gansu Province.Analyze the intelligent unmanned machine group composed of auto-pilot paving technology and roller auto-pilot technology.Design the optimal configuration model of highway construction machine group, and use multi-objective particle swarm algorithm to design the cooperative operation of unmanned machine group.Combined with the optimal configuration of highway construction fleet problem itself, the standard particle swarm algorithm and fleet configuration model are also modified and improved.Simulate the highway pavement construction process, emphasizing the preparation of construction personnel, machinery, and management platform.The parameters of particle swarm algorithm are designed to solve the optimal construction machine fleet optimization configuration under quality constraints of durationcost.The machine utilization and duration of scheme 2 are 15.23% and 10.96%, respectively.With the priority of duration, scheme 2 is selected as the machine fleet configuration scheme.Option 4 has the lowest machinery cost of 9.41%.With the priority to ensure the maximum profit, option 4 can be chosen as the machine swarm configuration scheme.
