AGV is the application of modern factory intelligence and automation. With the development of wireless power transmission (WPT), its transmission efficiency and stability are getting higher and higher. However, from static charging to dynamic power supply, the cost of technology implementation has increased significantly. This paper proposed a method to supply power to logistics AGV by intermittent segment, established the binary coverage model according to the power coverage distance, and designed an Adaptive Weight Value Multi-objective Genetic Algorithm (AWVMOGA) for this model to Optimizing the path design of sectional power supply. The influence of three weight value adaptive methods on the optimization results is analyzed, the effectiveness of the proposed method is analyzed and verified through case simulation.

Ultrasonic mist chemical vapor deposition (mist-CVD) process has been used to deposit bismuth-based cubic pyrochlore thin films for the first time. The crystal structure, morphology, and dielectric properties of Bi1.5MgNb1.5O7 (BMN) films grown in N2, air, and O2carrier gas are characterized. Sufficient O2is beneficial for the pure phase and highly crystallized cubic pyrochlore BMN thin films with a (2 2 2)-preferred orientation. Superior dielectric properties (dielectric constant 176, loss tangent 0.005, and tunability 29%@ ?1 MV cm?1) at 1 MHz are obtained. The results suggest that the mist-CVD method have potential in depositing high quality bismuth-based cubic pyrochlore thin films.
