RFID based AGV trolley capable of accurate positioning and working method of AGV trolley

Abstract

The invention discloses an RFID based AGV trolley capable of accurate positioning. The AGV trolley comprises a vehicle body, front wheels, back wheels, a mechanical arm device, a freight carrying case, a vehicle-mounted control case, a power switch and a push device, the front wheels and the back wheels are fixed in the bottom of the vehicle body, the freight carrying case is arranged on the vehicle body, the push device is mounted in the bottom of the freight carrying case, the vehicle-mounted control case is arranged in the right side of the vehicle body, and the mechanical arm device is mounted in the left side of the vehicle body. A master controller, a driving module, an RFID positioning module, a visual obstacle avoidance module and a preferential path selecting module are arranged in the vehicle-mounted control case, inductor visual cameras are arranged in left and right sides of the vehicle body respectively, and the output ends of the inductor visual cameras are connected withthe input end of the visual obstacle avoidance module. Thus, the AGV trolley capable of accurate positioning, transporting in an optimal path and automatic material movement, the machine visual module is provided for obstacle avoidance, an RFID technology is used to realize positioning and travelling of the vehicle, and the preferential path selecting module realizes transport in the optimal path.

Description

technical field [0001] The invention relates to the technical field of AGV trolleys, in particular to an RFID-based AGV trolley capable of realizing precise positioning and a working method thereof. Background technique [0002] AGV trolley refers to an unmanned transport vehicle equipped with automatic guidance devices such as electromagnetic or optical, capable of driving along a prescribed guiding path, with safety protection and various transfer functions, and using batteries as the power source. Generally, the traveling route and behavior can be controlled by a computer, or the traveling route can be established by using electromagnetic tracks and ribbons pasted on the floor. At present, the application of AGV trolley in the manufacturing industry is mainly to complete the material handling task efficiently, accurately and flexibly. [0003] However, electromagnetic rails and ribbons are stuck on the floor, which are easy to be polluted and worn, and may be disturbed b...
