Problems solved by technology
In the traditional electromagnetic tracking method, the sensor is fixed on the body of the AGV car, and its navigation can only strictly follow the fixed reference path, which lacks flexibility; in the case of complex paths, that is, multi-curve tracking, the running path of the car is the reference path. The path is long and the walking speed is slow

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.
Description
technical field [0001] The invention relates to a navigation system of an automatic guided vehicle, in particular to a navigation system based on electromagnetic induction tracking. Background technique [0002] Automated Guided Vehicles (AGV), also known as unmanned vans, first appeared in the 1950s. It is an automated, unmanned and intelligent handling equipment that belongs to a mobile robot system. The set path driving is an important equipment of the modern industrial automation logistics system. Not only that, in military and dangerous places, based on the automatic driving of AGV, it can inherit other detection and disassembly equipment, which can be used for battlefield demining, position detection and dangerous environment operations. [0003] The AGV mainly consists of a guide module, a walking module, a guide sensor, a microprocessor, a communication device, a transfer device and a battery. Among them, the guidance sensor is the key module of sensing the path an...
