A GPS visual navigation system for smart cars

Abstract

The invention discloses a GPS visual navigation system for an intelligent car, comprising an AGV vehicle-mounted subsystem, a GPS visual navigation server, a two-dimensional code mark arranged on each driving section of the AGV car, and a colored paper tape arranged on each driving section of the AGV car Guide bar; the AGV vehicle-mounted subsystem includes a GPS positioning module, a two-dimensional code scanner, an image acquisition module, a distance measuring sensor, an ARM processor, a vehicle communication module, an AGV general controller and an AGV driving device. The invention uses the GPS visual navigation server to formulate the transportation route for the AGV trolley to the transportation destination, and guides the driving of the vehicle based on the two-dimensional code identification and the colored paper tape guide strip of each driving section during the transportation process, and has the advantages of simple path setting , Easy to maintain and change the line and not subject to the advantages of external electromagnetic interference.

Description

technical field [0001] The invention relates to an AGV trolley, in particular to a GPS visual navigation system for an intelligent trolley. Background technique [0002] Automated Guided Vehicle (AGV for short), also known as AGV trolley, is equipped with automatic guidance devices such as electromagnetic or optical, can drive along the prescribed guiding path, and has safety protection and various transfer functions. The transport vehicle, the ACV trolley does not require a driver in industrial applications, and uses a rechargeable battery as its power source. The AGV trolley is characterized by wheeled movement. Compared with walking, crawling or other non-wheeled mobile robots, it has the advantages of fast action, high work efficiency, simple structure, strong controllability, and good safety. Compared with other equipment, the AGV's activity area does not need to lay track, support frame and other fixed devices, and is not limited by the site, road and space; therefore...

Problems solved by technology

[0003] In practical applications, most AGV cars use the electromagnetic path-following system to set up their travel routes, and the AGV cars move and move according to the information brought by the electromagnetic path-following system. However, the laying of the electromagnetic track is complicated, the cost is high, and It is not easy to maintain and rewire, and is easily affected by external electromagnetic field interference
