Abstract

The invention relates to the technical field of mobile robot navigation positioning, and aims at providing a GPS / INS navigation system with magnetic nail positioning assistance. When a robot carries out GPS navigation, the magnetic nail positioning technology is utilized for adjusting the direction to make the navigation more precise. According to the technical scheme, the GPS / INS navigation system with magnetic nail positioning assistance comprises a GPS data receiving and processing module, and is characterized by further comprising an inertial navigation system, an inertial navigation system processing module, several magnetic nails laid on the ground, a magnetic sensor module, a servo motor, a coder module and a central processing unit controlling the servo motor; the central processing unit comprises a Kalman filtering module and a servo motor control module; the inertial navigation system and the inertial navigation system processing module are electrically connected with the Kalman filtering module of the central processing unit in sequence, and the GPS data receiving and processing module is electrically connected with the Kalman filtering module of the central processing unit.

Description

technical field [0001] The invention relates to the technical field of mobile robot navigation and positioning, in particular to a GPS / INS navigation system assisted by magnetic nail positioning. Background technique [0002] The automatic navigation technology of mobile robots has applications in many aspects, such as the mechanization and precise operation of agricultural machinery, detection and search in extreme environments, and unmanned driving of various vehicles. The positioning accuracy of today's GPS navigation system in civilian use can reach within 10 meters, but there is still a certain error, and it is easily affected by the environment. In bad weather, the navigation accuracy is insufficient, and the real-time performance is not high, so it is difficult to achieve effective control. Therefore, the research on the automatic navigation and positioning technology of mobile robots has important practical significance and strong practicability. Contents of the in...
