Embodiment Construction
[0009] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0010] In the embodiment of the present invention, the traffic control system includes: a traffic controller, a laser AGV, at least one magnetic navigation AGV, the laser AGV and the magnetic navigation AGV communicate wirelessly with the traffic controller,
[0011] The laser AGV travels between the two destinations according to the set two-way driving path, and the magnetic navigation AGV circulates between the two destinations according to the set one-way circulation path. The two destinations usually refer to the pick-up point and the unloading point;
[0012] The magnetic navigation AGV and th...

The invention is applicable to the technical field of guiding transport vehicles, and provides a traffic control system for an AGV under hybrid navigation. The system comprises a traffic controller, alaser AGV and at least one magnetic navigation AGV. The laser AGV and the magnetic navigation AGV are in wireless communication with the traffic controller, the laser AGV travels to and from two destinations according to a set two-way travel path, and the magnetic navigation AGV circulates between the two destinations according to a set one-way circulation path, the intersection and possible intersection of the laser AGV travel path and the magnetic navigation AGV travel path is locked area defined by the center, the traffic controller guides the magnetic navigation AGV and the laser AGV through the locked area successively orderly through the locking and unlocking of the locked area; when the locked area is locked, the magnetic navigation AGV and the laser AGV passing through the lockedarea are controlled to be stopped immediately; when the locked area is unlocked, the stopped magnetic navigation AGV and the stopped laser AGV corresponding to the locked area are controlled to be started according to a set sequence, and the magnetic navigation AGV and the laser AGV continue to drive according to the respectively set paths.
Description
technical field [0001] The invention belongs to the technical field of guided transport vehicles and provides an AGV traffic control system and method under mixed navigation. Background technique [0002] Automated Guided Vehicle (AGV for short) is a kind of mobile robot. It refers to a transport vehicle equipped with automatic guidance devices such as electromagnetic or optical, capable of driving along a prescribed guiding path, and having safety protection and various transfer functions. , which is an important equipment in modern manufacturing and logistics systems, mainly used to store and transport various materials, providing an important guarantee for the system's flexibility, integration and efficient operation. [0003] With the development of science and technology, a single AGV navigation method can no longer meet the needs of large-scale projects, such as not only the AGV with the aid of magnetic navigation that needs to transport the material truck shelf, but a...
