基于萤火虫算法的磁信标自主定位方法

传统定位和跟踪应用(如雷达和GPS等)受天气、地域的限制,无法适应室内、地下、水下等应用场合,对此研究了一种低频磁信标定位方法,可穿透土壤、岩石、海水、建筑物和许多其他类型的介质,不受恶劣的天气条件或昼夜变化的直接影响,在许多室内和室外环境中应用十分方便。针对传统磁信标定位存在的问题,分析了分离式磁信标定位的原理,给出了萤火虫算法在磁信标定位中的数学模型,提出了一种基于萤火虫算法的磁信标自主定位方法,该方法适应性更强,更易于工程实现,最后通过仿真和实验验证了该方法的可行性。

Magnetic Beacon Autonomous Positioning Method Based on Firefly Algorithm

As traditional positioning and tracking systems, such as radar and GPS, are limited by weather and geography, and cannot adapt to indoor, underground, underwater and other applications, a low-frequency magnetic beacon positioning method is studied. With quasi-static magnetic field, which can penetrate soil, rock, seawater, buildings and many other types of media, this method can be easily used in many indoor and outdoor applications without direct affection by harsh weather conditions or day and night changes. Aiming at the problems of traditional magnetic beacon positioning, the principle of magnetic beacon positioning is analyzed. The mathematical model of firefly algorithm in magnetic beacon positioning is given. A method of magnetic beacon autonomous positioning based on firefly algorithm is proposed. The method is more adaptable and easier to implement. Finally, the feasibility of the method is verified by simulation and experiment.
