《自动化技术与应用》 2022 年第 41 卷第 6 期 通信与信息处理 Communication and Iprocessing is realized; the whale algorithm is divided into three processes: foraging, shrinking encirclement and predation, the mathematical model of each process is determined, and then mutation, crossover and other operations are added to improve the performance of the algorithm. Com- bined with the characteristics of the algorithm, the system mode is set from three aspects of client, logic and server to complete data acquisition, format transformation, data sorting and visual extraction. The simulation results show that the aspect ratio perfor- mance of the system is good, and the continuity and security of the data are guaranteed.
