What is the core technology of AGV? Here are two key technologies of AGV.They are: 1. Positioning and navigation; 2. AGV scheduling.
Positioning and navigation
As for AGV cars, the first thing to know is that “where am I” is also a positioning question, then “where am I going” is a scheduling question, and then “how to get there” is a navigation question.Positioning and navigation often complement each other. For indoor positioning and navigation, the traditional positioning methods are magnetic strip, tape and so on. The advantages and limitations of these methods are obvious. The advantages are controllable movement path and high security.
The more sensitive positioning methods include laser reflector, magnetic nail, two-dimensional code and other features. These plans will use artificial preset features to locate the lighthouse in the ocean. When AGV sees the lighthouse, it will know where it is.More typical, and then two-dimensional code to locate.
Another way of thinking is similar to GPS positioning, as for the inertial navigation, it is better to use GPS positioning
And natural navigation, more is used to assist positioning, and the previous several navigation methods blend.The other one that does not need to be constructed is differential GPS, which uses a standard GPS bearing reference station to correct the AGV bearing. The positioning accuracy and delay may be the problems that need to be solved.
