Description

technical field [0001] The invention relates to the field of magnetic navigation sensors, in particular to an AGV magnetic navigation data optimization processing system. Background technique [0002] The magnetic navigation sensor for AGV (automated guided vehicle, automatic guided vehicle) is an important navigation tool for AGV. It is fixed at the bottom of the AGV to sense the position of the magnetic track. The accuracy of position perception directly affects the operation control accuracy and stability of the AGV. Magnetic navigation sensors usually sense magnetic signals through evenly arranged multiple magnetic induction units, but the gap between the magnetic induction units not only reduces the positioning accuracy, but also generates discontinuous positioning signals. [0003] With the structural upgrade of the industrial environment, the requirements for the navigation and positioning accuracy of AGV are getting higher and higher, and the accuracy of traditional ...

[0003] With the structural upgrade of the industrial environment, the requirements for the navigation and positioning accuracy of AGV are getting higher and higher, and the accuracy of traditional magnetic navigation sensors can no longer meet the requirements

In addition, in the factory application environment, due to the application and external factors, the laid magnetic track is usually damaged, resulting in the runaway of the AGV trolley.
