Electromagnetic sensing tracking based navigation system

The invention relates to an electromagnetic sensing tracking based navigation system which is mounted on an automatic navigation vehicle and comprises a sensor unit, a microprocessor, a servo steering engine, a steering engine and an external support. The servo steering engine is arranged on the automatic navigation vehicle and is connected with the sensor unit through the external support. The microprocessor is respectively connected with the servo steering engine and the sensor unit, and the steering engine is connected with the server steering engine. The sensor unit senses the current environment information of the automatic navigation cart and transmits the same to the microprocessor. The microprocessor transmits controls signals to the servo steering engine according to the acquired environment information. The servo steering engine controls the external support to steer so that the sensor unit can be always at the reference position. The steering engine controls steering of front wheels according to angle of the servo steering engine and navigation is completed. Compared with the prior art, the electromagnetic sensing tracking based navigation system has the advantages that running efficiency of an AGV (automatic guided vehicle) on the complicated path can be improved, and the like.
