Embodiment Construction

[0028] The automatic guided vehicle (AGV, Automatic Guided Vehicle) based on the ultrasonic range finder has a better environment and a relatively flat road. It can be approximated that the AGV based on the ultrasonic range finder operates in a two-dimensional horizontal plane. The AGV based on the ultrasonic range finder uses the heading angle obtained by the gyroscope, the displacement obtained by the displacement encoder, and the distance value obtained by the receiving device of the ultrasonic range finder. The running path of the AGV of the distance meter, and then control the operation of the driving device through the drive controller, and then drive the operation of the AGV based on the ultrasonic rangefinder.

[0029] combined with Figure 1~3 , an automatic guided vehicle based on an ultrasonic rangefinder, including a drive chassis (not shown), an automatic guided vehicle body (not shown) and a driving device (not shown); it also includes a gyroscope set on the auto...

Abstract

The invention relates to an automatic guide vehicle, an automatic guide system and a navigation method based on an ultrasonic range finder. The automatic guide vehicle comprises a drive chassis, an automatic guide vehicle body, a drive device, a gyroscope, a displacement encoder, a drive controller, an ultrasonic range finder receiving device and a controller, wherein the automatic guide vehicle body and the drive device are arranged on the drive chassis, the gyroscope, the displacement encoder, the drive controller, the ultrasonic range finder receiving device and the controller are arranged on the automatic guide vehicle body, and the gyroscope is used for acquiring a driving course angle of the automatic guide vehicle based on the ultrasonic range finder; the displacement encoder acquires the driving displacement of the automatic guide vehicle based on the ultrasonic range finder; the drive controller controls the drive device; the ultrasonic range finder receiving device which is arranged on the automatic guide vehicle body receives an ultrasonic signal and calculates a transmission distance value of the ultrasonic signal; and the controller is respectively electrically connected with the gyroscope, the encoder, the drive controller and the ultrasonic range finder receiving device and calculates a running route of the automatic guide vehicle based on the ultrasonic range finder according to the acquired course angle, the displacement and the distance value and controls the drive device to run through the drive controller.

Description

technical field [0001] The invention relates to automatic guided vehicle technology, in particular to an automatic guided vehicle, system and navigation method based on an ultrasonic rangefinder. Background technique [0002] AGV (Automatic Guided Vehicle) refers to an automatic guided vehicle, which is an unmanned automated handling vehicle powered by a battery and equipped with a navigation system. The salient feature of AGV is unmanned driving. Using the automatic navigation system, the AGV can automatically drive along the predetermined route without manual piloting, automatically transport the goods from the starting point to the destination, and can meet the requirements of the storage location. , the production process and other changes can be changed flexibly, and it has the advantages of good flexibility, high degree of automation and high level of intelligence, so AGV has been researched in many industries such as mechanical processing, material assembly, home appl...
