Abstract

The invention relates to an inertial integrated navigation system based on magnetic nail deviation correction and position encoder assistance. The inertial integrated navigation system comprises a main controller, wherein the main controller is connected with a magnetic nail sensor, a position encoder, an inertial sensor and a communication interface, the position encoder is used for calculating an AGV vehicle running distance and transmitting the AGV vehicle running distance to the main controller; the inertial sensor is used for measuring AGV angle variation data, and transmitting the AGV angle variation data to the main controller to serve as a main basis for AGV attitude control; and the communication interface is used for transmitting data processed by the main controller to a higher-level control system. The inertial integrated navigation system based on the position encoder and magnetic nail deviation correction reduces maintenance cost, improves navigation precision, and is wider in application occasion.
