There are various types of AGV transfer vehicles, but which one is more suitable for factory floor use? We will introduce the classification of AGV transfer vehicles and their characteristics, performance, use.
1, Electromagnetic Induction-guided AGV
Electromagnetic induction guidance is generally on the ground, along the pre-set driving path buried wire, when the high-frequency current flow through the wire, the wire around the electromagnetic field, AGV on the left and right symmetrical installation of two electromagnetic sensors, they receive the electromagnetic signal strength differences can reflect the AGV deviation from the path of the degree of the automatic control system to control the vehicle steering, continuous dynamic The continuous dynamic closed-loop control can ensure the stable automatic tracking of the set path by the AGV. This electromagnetic induction-guided navigation method is currently used in most commercial AGVS, especially for medium and large-sized AGVs.
2、Visual Guidance AGV
Vision-guided AGV is a rapidly developing and mature AGV, this kind of AGV is equipped with CCD cameras and sensors, set in the vehicle computer AGV want to drive the path around the environment image database; AGV driving process, the camera dynamically obtains the vehicle around the environment image information and comparison with the image database, so as to determine the current position and make decisions on the next step.
3、Laser-guided AGV
This type of AGV is equipped with a rotatable laser scanner, and laser positioning markers with highly reflective plates are installed on the walls or pillars along the running path, and the AGV relies on the laser scanner to emit laser beams and then accepts the laser beams reflected back from the surrounding positioning markers, and the on-board computer calculates the current position of the vehicle and the direction of movement and corrects the orientation by comparing with the built-in digital map. The vehicle computer calculates the current position of the vehicle and the direction of movement and corrects the orientation by comparing it with the built-in digital map, thus realizing automatic handling.
At present, the application of this type of AGV is becoming more and more common. For example, if the laser scanner is replaced by an infrared emitter or ultrasonic emitter, the laser-guided AGV can become an infrared-guided AGV and an ultrasonic-guided AGV.
The above is the working principle of AGV, hope it can help you when choosing!
