Abstract

The present invention relates to an automatic guide method of intelligent industrial transportation vehicle and electric vehicle adopting said automatic guide method. The visual guide method of automatic guide vehicle controlled by computer is characterized by that the camera mounted on the automatic guide vehicle can be used for shooting the running path mark line on the pavement, station address code identifier and running state control identifier, and the computer connected with the camera can utilize image intellectualized identification to obtain the position deviation and direction deviation parameters of the vehicle body and running path mark line and station address and running state control information to give out correspondent control signal to wheel drive mechanism controller to implement automatic guide control of the automatic guide vehicle.

Description

technical field [0001] The invention relates to an automatic guidance method of an intelligent industrial transport vehicle used in a logistics system and an intelligent electric vehicle adopting the automatic guidance method. Background technique [0002] At present, the guidance technologies used in automatic guided electric vehicles (AGV for short) used in logistics systems mainly include embedded electromagnetic induction, laser reflection, ultrasonic reflection, optical reflection and track inference. However, the above-mentioned various AGV guidance technologies have great differences compared with the guidance methods based on visual image recognition in terms of path setting methods and costs, environmental space conditions and dimensions, guidance control accuracy and flexibility, and information collection capacity and content. difference. Among them, the guidance path setting of the embedded electromagnetic induction guidance method is complicated, the cost is hi...
