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

Embodiment Construction

[0015] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0016] Such as figure 1 As shown, a GPS visual navigation system for a smart car, including an AGV on-board subsystem, a GPS visual navigation server, a two-dimensional code identification set on each driving section of the AGV car, and a colored paper tape guide set on each driving section of the AGV car strip;

[0017] The GPS visual navigation server is used to save the GPS positioning information and road section numbers of all AGV car driving sections in the transportation area, and formulate the shortest route to the transportation destination according to the GPS positioning information and transportation destination information uploaded by the AGV vehicle subsystem in real time. The transportation route is issued to the AGV on-boar...

Abstract

The invention discloses a GPS visual navigation system of a smart car. The GPS visual navigation system comprises an AGV (automated guided vehicle) vehicle-mounted subsystem, a GPS visual navigation server, two-dimensional code identifiers arranged on all the driving sections of an AGV trolley, and colored paper tape guiding strips arranged on all the driving sections of the AGV trolley. The AGV vehicle-mounted subsystem includes a GPS positioning module, a two-dimensional code scanner, an image acquisition module, a ranging sensor, an ARM processor, a vehicle-mounted communication module, anAGV universal controller, and an AGV driving device. The invention develops a transportation route of the AGV trolley to a transportation destination through the GPS visual navigation server, and guides vehicle driving based on the two-dimensional code identifiers and the colored paper tape guiding strips arranged on all the driving sections during transportation, is simple in path setting, can easily maintain and change the path, and is free from 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...
