Weigh-in-motion or weighing-in-motion (WIM) devices are designed to capture and record the axle weights and gross vehicle weights as vehicles drive over a measurement site. Unlike static scales, WIM systems are capable of measuring vehicles traveling at a reduced or normal traffic speed and do not require the vehicle to come to a stop. This makes the weighing process more efficient, and, in the case of commercial vehicles, allows for trucks under the weight limit to bypass static scales or inspection.
AGV double-vehicle linkage adaptive motion control method and system
The application discloses an AGV double-vehicle linkage adaptive motion control method and system, and belongs to the technical field of industrial automatic logistics equipment. The method integrates the double vehicles into a unified rigid whole by constructing an eight-steering-wheel virtual rigid body motion model; communication delay compensation is realized by using a dynamic clipping and interpolation algorithm based on a time queue; and a sliding mode control algorithm fusing a quadratic term of a distance error and an error change rate is used to quickly converge a cooperative error. The application effectively solves the technical problems of poor trajectory consistency and large synchronization error caused by model fragmentation, communication delay and external disturbance in the cooperative motion of heavy-load AGVs, and significantly improves the cooperative motion precision and anti-interference ability of heavy-load logistics equipment.
